What Laptop Would Be Best?

Personally prefer Toshiba brand. My Husband and I have owned a few laptops(2 Toshiba's and 4 HPs/Compaq) and Toshiba by far has outlasted all the others and runs a lot cooler to the touch after being on for a few hours. My luck with HP has not been that great, they tend to over heat after a while and it will eventually cause the entire thing to just shut down on you randomly. Not to mention 3 out of the 4 HP's all had power supply's that flat out died on us after 1-2 years. My first Toshiba I bought back in 2006, the only reason why I upgraded this year was because my old one had integrated graphics card which does not support most games. I wanted one I could play games on, Im not a heavy gamer but yea Integrated graphics sucked-even with just looking at and editing photos off my digital camera. I have a Toshiba Satellite L645, its only 14in and does not have the number pad, but does have raised keys and mouse pad lock. Also has SD Slot, Built in webcam and mic. Cost around 700 from best buy with the extended warranty. Bought it back in Feb, they do have others tho around the same price range with the build in number pad and 17in screen. My old one is a 17in screen it was really nice, I do miss using the big screen. I also really like having the SD card slot because I do take a lot of photos. Most Toshibas come with that right on the front. One last note, my sister had an Acer and that thing was a pos it didnt last but like a year before it started over heating on her.

From the big screen to the small screen

Cartoons in the Golden Age, such as Red Hot Riding Hood, contained topical and often suggestive humor, though they were seen primarily as "children's entertainment" by movie exhibitors. This point of view prevailed when the new medium of television began showing cartoons in the late 1950s. One of the first images to be broadcast over television was that of Felix the Cat. In 1938, cartoonist Chad Grothkopf's eight-minute experimental Willie the Worm, cited as the first animated film created for TV, was shown on NBC. As TV became a phenomenon and began to draw audiences away from movie theaters, many children's TV shows included airings of theatrical cartoons in their schedules, and this introduced a new generation of children to the cartoons of the 1920s and 1930s. Cartoon producer Paul Terry sold the rights to the Terrytoons cartoon library to television and retired from the business in the early 1950s. This guaranteed a long life for the characters of Mighty Mouse and Heckle and Jeckle, whose cartoons were syndicated and rerun in children's television programming blocks for the next 30 to 40 years. There were a number of early experiments in limited animation television cartoons. These cartoons usually were about five minutes in length and were episodic in nature, allowing stations to flexibly program them.

One of the first cartoons produced expressly for television was Crusader Rabbit, a creation of Alexander Anderson and Jay Ward. Soundac, a small studio in Florida, was responsible for another early adventure serial, Colonel Bleep. Often, existing programs would be a launching ground for new cartoon characters. In 1956, the Howdy Doody show aired the first Gumby clay animated cartoon from creator Art Clokey. Sam Singer earned a certain degree of infamy for his efforts at television animation, which included an animated adaptation of The Adventures of Paddy the Pelican (which may or may not have made it to air) and the original series Bucky and Pepito, both of which have been cited as among the worst of their kind.

On the other hand, a long-running series of animated shorts named Tom Terrific was produced by Terrytoons for the Captain Kangaroo show, and this series was praised by film historian Leonard Maltin as "one of the finest cartoons ever produced for television." Beginning in 1954, Walt Disney capitalized on the medium of television with his own weekly TV series, Disneyland. This ABC show popularized his new Disneyland theme park and began a decades-long series of TV broadcasts of Disney cartoons, which later expanded into the show Walt Disney's Wonderful World of Color. While Disney recognized that the economics of the medium could not support his production standards and refused to go into TV animation, he still ordered the creation of one character exclusive to TV, Ludwig Von Drake. The character's segments would link compilations of the company's archived theatrical shorts as complete episodes. Walt continued to host the show for the rest of his life, and he became as recognizable to the TV audience as his studio's cartoon characters.

Hanna-BarberaThe first major animation studio to produce cartoons exclusively for television was Hanna-Barbera Productions. When MGM closed its cartoon studio in 1957, Hanna-Barbera began producing cartoons directly for television, finding an audience in the evening "family hour" time. The first animated series from Hanna-Barbera were NBC's The Ruff & Reddy Show and the first-run syndication entry The Huckleberry Hound Show, each of which followed a format of three shorts, each the approximate length of a one-reel short film. However, the studio hit its stride in 1960s with ABC's The Flintstones, the first half-hour animated sitcom. Like many of its immediate successors it was originally aired during prime time when the whole family would be watching television.

The Flintstones was the first of several prime-time animated series from Hanna-Barbera, which included The Jetsons, Top Cat, and Jonny Quest. But after the end of The Flintstones in 1966, Hanna-Barbera largely turned its efforts to the growing market for Saturday morning cartoons, outside of isolated series for first run syndication in the 1970s such as Wait Till Your Father Gets Home. Hanna-Barbera was notorious for using common tropes in its series. Its original series of the late 1950s through mid-1960s all featured anthropomorphic animals, usually an adult (who would in turn impersonate a well-known celebrity) and child, interacting with the humans of their environment. After the immense success of Scooby-Doo, Where Are You!, which premiered on CBS in 1969, the next decade of Hanna-Barbera's animated output would follow that show's formula: a group of teenagers solving mysteries or fighting crime, usually with the help of a wacky animal or a ghost. The many incarnations of Scooby-Doo ran uninterrupted on CBS and then ABC for 17 seasons.

During the late 1970s and early 1980s, Hanna-Barbera turned to adaptations of prime time sitcoms. It was not until The Smurfs in 1981 that H-B once again had anything successful outside the Scooby template; it, in turn, led to derivative series (The Snorks and Paw Paws). The late 1980s and early 1990s saw Hanna-Barbera join the numerous studios producing younger and junior versions of cartoon characters for the Saturday morning cartoon market, such as The Flintstone Kids and A Pup Named Scooby-Doo. Limited animationOne of the problems with producing animation for television was the extremely labor-intensive animation process. While theatrical short subjects were previously produced in six-month cycles or longer, network television needed a season of 10-20 half hour episodes each year. This led to a number of shortcut techniques to speed up the production process, and the techniques of limited animation were applied to produce a great number of quickly-produced, low-budget TV cartoons.

Hanna-Barbera also used limited animation for artistic reasons: with smaller, low-resolution screens, the company's namesakes reasoned that a limited style that focused on dialogue and close-up shots with bold outlines worked better than the fully detailed animation used in film shorts, which were designed for large theater screens. The UPA studio was one of the first victims of the TV-animation market. In 1952, because of his left-wing social activism, John Hubley was dismissed from the studio under pressure from Columbia Pictures (who was itself under pressure from the HUAC). The creative atmosphere post-Hubley was not the same and UPA's theatrical shorts ended in 1959. In order to stay afloat financially, UPA turned to television to sustain itself. The TV versions of Mister Magoo and Dick Tracy were not successful and did nothing to reverse the studio's financial decline. In spite of the 1962 animated feature Gay Purr-ee (distributed by Warner Bros.), which featured the voices of Judy Garland and Robert Goulet and a Harold Arlen/Yip Harburg song score, and the beloved animated special Mr. Magoo's Christmas Carol, UPA was shut down in 1964. The Jay Ward studio, producer of The Rocky and Bullwinkle Show, used limited animation in its series, but compensated with its satire of Cold War politics and popular culture and its off-beat humor. Like the earlier Crusader Rabbit, the Rocky and Bullwinkle adventures were multi-part serials.

The Ward studio also produced George of the Jungle, Super Chicken, and Tom Slick. It later produced a series of popular television commercials for Quaker Oats cereals Cap'n Crunch, Quisp and Quake. Another company that used the same animation studios as Jay Ward did was Total Television, most famous for The Underdog Show. Total Television and Jay Ward animated productions were often mixed and aired together in syndication, leading to the two companies' shows to sometimes be confused with each other. Filmation, headed by Lou Scheimer and Norm Prescott, was another television animation studio that arose in the 1960s. Filmation was most famous for its acquisition of licenses to produce animated series based on other media; it was one of the few companies to keep all of its animation within the United States and did not use the aesthetics of limited animation preferred by Hanna-Barbera and UPA; instead, Filmation productions relied on heavy usage of stock footage, rotoscoping, limited voice casts (Scheimer himself provided many voices) and a balance of licensed animated series with lower-budget, live-action ones (such as The Ghost Busters and Uncle Croc's Block) to stay financially solvent.

After a string of success lasting well into the 1980s, Filmation dissolved in 1989. One of the most infamous users of limited animation was Cambria Studios, which invented and patented a process known as Syncro-Vox, implementing it beginning in 1960. While the process resulted in an extremely economical, quick and inexpensive product (thus making it ideal for television), it had a fatal flaw that prevented it from being taken seriously: the process involved inserting the moving lips of the voice actor over a still frame of a character's mouth. The result was that Cambria's cartoons (Clutch Cargo, Space Angel and Captain Fathom) contained hardly any animation at all, and were effectively pictures (albeit well-drawn ones that were of greater detail than other producers') with words. Cambria switched to a more mainstream limited animation process with The New Three Stooges in 1965, but went out of business shortly afterward.

Is the Big Screen Smart Refrigerator Worth Buying
Is the Big Screen Smart Refrigerator Worth Buying
With the development of artificial intelligence, Internet of things and smart home, it seems that all home appliances are attached with "intelligent attributes" for a moment. Small to "intelligent electric toothbrush" and intelligent toilet cover; As big as smart TV, only air conditioning, smart washing machine and so on. Household appliances, including refrigerators, are tending to be high-end with the help of intelligent technology.Nowadays, many refrigerator manufacturers directly integrate a huge display screen on the refrigerator door. It seems intelligent, but it is not. Some functions seem "mentally retarded" for our daily use. Is your refrigerator "mentally retarded"?Smart refrigerator with huge display screen. Here are some functions that are not necessarily easy to use. First of all, let's talk about this huge touch screen. The impression that "it's smart with a large screen" has been branded in people's hearts for many years. To tell you the truth, a large high-definition touch screen embedded on the refrigerator door will indeed highlight the sense of science and technology of the whole refrigerator, but I think it is not practical. It will be hot for three days after buying it, and it will almost never touch it again after playing enough. In addition, it will increase the power consumption of the refrigerator. If the software system of the built-in computer is not updated frequently, it may cause jamming for a long time, The user experience will be very poor. Moreover, the cost of the screen will also increase the overall selling price of the refrigerator.The screen embedded in the refrigerator door will also increase the thickness of the refrigerator door, otherwise the volume in the refrigerator will have to be compressed. With the current manufacturer's technology, the two will be contrary, which will also bring some design obstruction to the refrigerator manufacturer. These so-called "intelligent" functions are installed on your refrigerator. Are they intelligent or mentally retarded? For future events, please look downPracticability scoring of huge touch screen: TBDNext, let's talk about the functions integrated in the screenWhen it comes to video players, almost a LCD screen can realize this function. To be based on the huge display screen with computer chips on the refrigerator is nothing more than adding a little code. But do you really need this function? Do you watch TV dramas and movies while cooking? If so, does your family still buy TV? Move a stool and sit in front of the refrigerator every day. I feel embarrassed to think about this picture... Myself: XXScore for practicability of refrigerator video playback function: 30For the function of intelligent menu, some people may need to follow it to make some unfamiliar but wanted dishes. But now smart phones are so convenient, why do you have to use this function on the refrigerator? It will be really convenient? Generally, the stove in our home is facing the wall. Is it difficult to cook? Do you have to frequently look back at the guidance of the refrigerator??? Hahaha, it's a test for the neck, unless your home is an open kitchen... You have to find a good place for the refrigerator to see this screen at any time.

AI voice assistantThe function of built-in voice assistant in household appliances is now common, but it is still a new thing in the field of refrigerator. The birth of AI voice assistant is to liberate both hands and let the machine control the computer chip through the voice commands sent by people to complete some functions that usually need manual adjustment. Then put this function on the refrigerator and I'll think, can I chat with my refrigerator? Or can you control the temperature of each layer of the refrigerator? If I knew how cold something should be, why would I use it. So what can the voice assistant of the refrigerator do? In fact, it will be more convenient to use it well. For example, tell the refrigerator that I put a piece of salmon on the first floor of the refrigeration area. When the refrigerator receives this information, it will automatically adjust according to the optimal refrigeration temperature of salmon, and other similar operations. Only in this way can it really play the role of "assistant" of artificial intelligence. There are also many functions that can be accomplished by voice assistant, such as asking about today's weather... EMM... In addition, while adding voice assistant, some relevant voice detection components and speakers are also indispensable, which is also an expense packaged in the total price of the refrigerator. Don't kidnap my money!Refrigerator AI voice assistant function practicability score: 50When it comes to intelligent technology, combined with the refrigerator, the most practical is intelligent temperature control technology. The performance of temperature control in many refrigerators is not ideal, but the smart refrigerator applies fine control air duct technology. This is a project that can provide differential air through multiple air supply outlets according to different temperature requirements in various areas of the refrigerator, so as to achieve accurate temperature control. This improves the working efficiency of the refrigerator, and the temperature rise and fall range is small in the process of use, and the fresh-keeping effect will be more ideal. This function is still very worthy of the majority of users to pay for it. If I buy a smart refrigerator, I must use this function. It smells good!Score for practicability of intelligent temperature control function of refrigerator: 95The function of personal identification bright screen sounds very high-end. In fact, it has been used on mobile phones for a long time. In our daily phone calls, when the mobile phone is close to the ear to answer, the screen will be black. This is to prevent the face from touching the screen by mistake. The personal identification bright screen of the refrigerator just reverses this function. When someone approaches the refrigerator, the large screen will automatically light up. When the distance sensor detects that someone is far away from the refrigerator, it will automatically adjust the screen standby, which will save some of the power consumed by the screen.To be honest, the function of body fat detection should not appear on the refrigerator screen. The scale can be configured as standard. Imagine that there are delicious fruits, desserts and cold drinks in the refrigerator. As soon as you go to the door of the refrigerator, the large screen automatically displays your body fat rate. At this time, will you open the refrigerator door to get these delicious food? It's terrible to thinkThese two functions have their own advantages and disadvantages, but adding these two functions must be equipped with distance sensors, cameras and other components. With rich functions, the price is also piled up.Refrigerator personal identification screen body fat detection function practicability score: 40In fact, it is not difficult to realize the Bluetooth phone function. Many smart speakers sold on the market can realize this function through Bluetooth connected mobile phones. To be honest, the Bluetooth phone function in the refrigerator also belongs to chicken ribs. Cook in the kitchen. When you call, will you answer the phone directly with the refrigerator? Won't the noise of frying spoon affect the quality of answering? Functions are available but not easy to use, which is typical. Spicy chicken!Score for practicability of refrigerator Bluetooth phone function: 10See these words, you may not understand, refrigerator internal monitoring? Monitor if anyone stole my iced coke? In fact, I just know this function. Sometimes I have similar questions. After understanding, I know what this monitoring means. In fact, it is not so deep. It is to display the items stored in the refrigerator on the display screen on the refrigerator door through the camera inside the refrigerator. In this way, you don't have to open the refrigerator door to know what is in the refrigerator, where all kinds of food are placed and how many are there, which is convenient to take and add quickly. This feature may save some power consumption (but not much) for the refrigerator. I think it's better to have this.Score for practicability of internal monitoring function of refrigerator: 60The function of refrigerator door with ice cube comes from foreign refrigerator products. Foreign refrigerator manufacturers have specially designed this function for foreign families according to the habit that foreigners like to drink iced water and cold wine. It is indeed a very humane design for foreigners to use everyday, but most people in China love to drink hot water. In ancient times, they also need to heat their Baijiu, and there is little family that can often use this function. In a very special case, you sprained your foot when playing basketball. You need ice. But you can only sprain once in a few years. If you sprained your foot often, you wouldn't use this function. You would have gone to the hospital... (far away)This function has been moved to the domestic refrigerator market by major refrigerator factories, which can be described as a mockery. Under the banner of "customization for high-end people", manufacturers add these seemingly intelligent and actually "mentally retarded" functions for what, not just to increase sales and make more money. I don't think it's necessary. As a practical and cost-effective refrigerator that people like, the market acceptance will be improved, and the brand reputation will not be too low.
Apple still Uses Cheaper LCD Screens and Decides to Produce Them by Itself, Endangering the Interests of Many Screen Suppliers
Apple still Uses Cheaper LCD Screens and Decides to Produce Them by Itself, Endangering the Interests of Many Screen Suppliers
It is reported that Apple plans to use cheaper LCD screens on most iPhone models next year, while delaying the full conversion to high-tech organic light emitting diode (OLED) screens, which also reflects consumers' price sensitivity.According to the Wall Street Journal, apple is expected to launch an LCD model and two OLED models this fall, and the LCD model is expected to account for most of its iPhone sales. It is expected that Apple will continue to use LCD next year, which is completely inconsistent with the previous report of a complete transition to OLED.Apple announced in March that it was testing its internal microled screen.Apple's decision to insist on using cheaper LCD screens has brought more uncertainty to its screen suppliers; In addition, Apple's decision to produce its own screen endangers the interests of many suppliers.Since apple is not expected to use these products in its OLED screen, the shares of Apple's three LCD suppliers, including sharp, LG display and Japan display, have fallen sharply in the past year. Subsequently, when it was revealed in March that Apple was already testing its microled screen, the shares of many display suppliers, including Samsung, sharp and LG display, fell again. This also damages the interests of general display and Synaptics. After reports showed that Apple would use more LCD screens than expected, the share price of general display company, which provides OLED display materials, began to fall.The Wall Street Journal pointed out that Apple's decision to postpone the implementation of OLED screens does not necessarily bring opportunities for LCD suppliers. For example, LG display has planned to invest in OLED screens.Apple has been facing the problem of supply shortage in the past. If suppliers have to change their production plans, Apple may face supply shortage again. It is reported that Japan display raised $320 million in April to meet the expected demand for its advanced LCD.According to recent reports, Apple has communicated its transformation plan to its suppliers, including plans to reduce parts procurement from suppliers by nearly 20% this year. At the same time, the uncertainty of the continuous expansion of Apple's supply chain will also make the new iPhone more expensive than ever.

Principle of Touch Screen Capacitance Screen_ What Are the Application Areas of Touch Screen
Principle of Touch Screen Capacitance Screen_ What Are the Application Areas of Touch Screen
Principle of touch screen capacitance screenTouch screen is the most friendly computer user interface at present. It is more and more widely used in consumer electronic products. The touch detection device and touch screen controller are good. The mechanical structure of the detection device is damaged in the process of touch screen device, resulting in the decline of touch accuracy and shortening of service life of the touch screen; In addition, the cost of commonly used capacitive and resistive touch screens is relatively high. Inductive touch screen can avoid damage to the touch detection device during touch and prolong the service life of touch screen products.The working principle of inductive touch screen, as well as the hardware circuit and part of the program design of the controller, all of the controller circuits have passed the verification. The non-direct contact touch of inductive touch screen avoids the damage to the touch detection device, prolongs the service life of the whole touch control system, and the repetition accuracy and touch sensitivity of touching the same point meet the expected design requirements.The capacitive induction touch screen is not affected by dirt, dust or oil stains, but it will be affected by the surrounding environment to varying degrees because it adopts the electric field coupling principle. At the same time, the capacitive induction touch screen has serious drift phenomenon.What are the application areas of touch screenTouch screen has become a hot spot in the market. In the market, shopping malls, hotels and other places, it is still dominated by smart phones. The growth momentum of the smartphone market slowed down and entered a period of gentle development. The application of touch screen outside mobile phones, such as automotive electronics, retail, medical treatment, public facilities, leisure and entertainment, will promote the rapid growth of touch screen market.In addition to applications in large fields, touch screens can be innovated in subdivided fields. In the field of "pen writing tablet", innovate the touch screen.The products have been extended to tablet with pen writing function, e-book, all-in-one machine, electronic whiteboard, etc. And the pen and hand can be used at the same time. When one hand is touching, the pen can also write at the same time.The traditional materials of capacitive touch screen are ITO, metal grid, nano silver wire, carbon nanotube, conductive polymer, graphene, etc. Metal mesh and nano silver wire have more supporters. Both materials are metals (silver or copper) and their conductivity is better than ITO.
Screen Fingerprint Identification Will Be Applied to LCD Screen, Not Just OLED
Screen Fingerprint Identification Will Be Applied to LCD Screen, Not Just OLED
Fingerprint identification on mobile phones has become an indispensable part of our daily life.Especially during the epidemic, face recognition is mostly paralyzed due to wearing masks, and fingerprint recognition has become the current optimal solution.Of course, if you use a mobile phone without fingerprint identification such as iPhone x, you have to find a way by yourself...9to5mac also gave a tutorial on using face ID with mask Screen fingerprint identification has become the mainstream, and the technology is also very mature. However, Tony saw a news while surfing the Internet today, saying that Tianma, a domestic LCD and LCM design company, released the world's first LCD Screen multi-point fingerprint identification scheme (Ted finger print, referred to as TFP).The strength of this scheme is that the off-screen fingerprint identification mobile phones we use now are basically OLED screens, while the LCD screen basically has no on-screen fingerprint identification...One plus 6T off screen fingerprint identification diagram As we all know, the screen fingerprint unlocking needs the illumination of the light source for fingerprint identification, but the LCD screen is relatively thick and has poor light transmittance; Second, the LCD screen cannot emit light actively, and the backlight will interfere with the identification of optical fingerprints.These two problems make LCD basically bid farewell to screen fingerprint recognition.Therefore, mobile phones with LCD screen basically adopt side fingerprint identification, and some will be combined with the power key on the side of the mobile phone.But OLED screens don't have this problem. Because the OLED screen is thinner and more transparent, it is natural to use fingerprints on and off the screen.Then why do manufacturers not directly on the OLED screen, but want to operate madly on the LCD screen? The reason is also simple: because LCD screens are cheap...Although Lu Weibing, vice president of Xiaomi, said publicly some time ago that Hongmi team successfully realized fingerprint recognition under LCD screen on a redmi note8 Pro prototype, so far, no manufacturer has officially announced this technology, and Tianma is the first.So Tony was surprised when he saw the news. This fingerprint identification scheme can be said to break through the two obstacles of current screen fingerprint identification technology - LCD screen and identification area.If the multi-point fingerprint identification in the LCD screen can achieve mass production, it means that the LCD screen can also use fingerprint identification!Another point is the identification area of off screen fingerprint identification.So far, the identification area of screen fingerprint is basically fixed, almost at the lower position of the screen. People will subconsciously put their fingers at the approximate position when unlocking the mobile phone.But no one can guarantee that every time the finger is pressed on the fingerprint identification area, because the identification area is so large, it is inevitable that there will be deviations...The scheme announced by Tianma this time shows that it can make the whole LCD screen recognize fingerprints!Tony mended his brain, that is, I could identify my fingerprint and unlock my mobile phone by placing my finger anywhere on the screen.If this multi-point fingerprint identification technology can be mass produced, the efficiency of unlocking the screen will be much higher than now. You don't have to find the identification area and poke it on the screen.It can be said that Tianma's operation directly makes the LCD screen ride on the head of OLED in fingerprint identification. Once LCD screens didn't even deserve fingerprint identification. Now they not only have fingerprint identification, but also can identify 5 at a time...As for why the multi-point fingerprint solution in the TFP screen can realize these functions, high integration has played a great role.In short, it is to integrate touch, display and fingerprint identification, replace the previous design of fingerprint identification module and reduce the thickness of the screen, so that the screen fingerprint identification is feasible on the LCD.At the same time, in order to realize fingerprint identification on the whole screen, Tianma covers the whole screen with optical path and sensors.As for how multi-point fingerprint identification can play new tricks, it still depends on the subsequent operations of manufacturers.As for the fate of LCD screen after mass production of this scheme, we still don't know, but before that, LCD screen has never been the first choice for mobile phone manufacturers.After all, the OLED screen is thinner, can emit light by itself, and the color is more bright. The experience is much better than that of LCD, but there are still problems of stroboscopic and screen burning, and the price is relatively expensive.When it comes to the LCD screen, the advantages and disadvantages are reversed...The price of iPhone 11 with LCD screen is lower For most users, OLED screen is their first choice, but there are still a group of people who stick to the LCD screen.In addition to having a larger viewing angle, another reason is that they can't accept the strobe of OLED screen. They think it's really hurting their eyes...Therefore, once the TFP scheme realizes mass production, the defect that the LCD screen has no off screen fingerprint will be supplemented. If the price can be controlled well, the current situation of the screen in the mobile phone market may change a lot.However, before that, the mobile phone market was still dominated by OLED screens, not to mention the suoper AMOLED screens such as Samsung. The evolution of LCD screens has a long way to go...

Every day, new products, new experiences, professional membrane switch proofing factory, 12 hour expedited shipmentFrom the hot sale of Samsung Galaxy edge flagship series to the advent of various curved screen bracelets and TVs, it is no doubt that curved screen technology has been widely valued and sought after by consumers and the industry in recent years. In the future, with the continuous development and improvement of fixed curvature curved screen technology, the flexible touch screen that can realize arbitrary bending will become an important development direction. On the 25th, at the 13th International touch screen and display technology development forum, Huang Hanfeng, deputy general manager of touch R & D from Shenzhen oufeiguang technology, made a detailed introduction to the flexible touch screen from the perspective of the industrial chain around the four key elements of flexible display, flexible touch, flexible cover plate and flexible bonding.Flexible displayFor LCD display, the LCD is usually responsible for controlling the display gray, and the three primary color filters control the display color, which requires them to correspond one by one in order to display normally. If the LCD panel is used as a curved screen, the inner circumference and outer circumference will be unequal, and the original one-to-one corresponding liquid crystal and filter will have position deviation, resulting in color distortion. In addition, it will also cause a series of problems such as light leakage, dark screen ghosting and snowflakes. Therefore, for the curved screen, the OLED display technology represented by AMOLED has almost become the best choice.Huang Hanfeng said that at present, Samsung is the undisputed AMOLED overlord in terms of patents, production capacity, yield and technology accumulation. The sixth generation AMOLED panel that began mass production at the end of 2014 can now produce 50000 pieces per month, and the yield can reach 60%. The second is LG, but LG has been focusing on large screen curved TV. At present, with the increasingly obvious trend of small screen AMOLED, LG is also accelerating the layout of small and medium-sized flexible screens. Although its output is not as good as Samsung, its yield can also reach more than 60%. The latest release of Xiaomi note 2 is the flexible AMOLED screen of LG. In addition, Japan's JDI and sharp (already acquired by Hon Hai), Taiwan's Youda, domestic BOE, Rouyu and other screen manufacturers are also accelerating the layout of their own AMOLED technology. It is the general trend for AMOLED to replace LCD.Flexible touchIn terms of touch control, ITO (indium tin oxide) transparent conductive film has become the most important touch layer material for display screens such as non curved LCD and OLED due to its good light transmittance, low thickness, excellent hardness and conductivity, mature manufacturing technology and many other reasons. However, as ITO itself is a brittle material, it is not suitable for making flexible touch layer with large curvature or even free bending, and the cost and cost are high. At present, it accounts for about 30% - 40% of the cost of the upstream material part of the whole touch screen industry, and uses "indium", a rare metal with limited reserves. Therefore, with the advent of the era of curved surface and flexibility, it is likely to be replaced.Huang Hanfeng said that at present, the main substitutes for ITO materials are graphene, carbon nanotubes, nano silver and metal mesh. Graphene and carbon nanotubes are very good substitutes for ITO from the characteristics of the material itself. However, graphene is still in the R & D stage and is still far from mass production. The industrial mass production technology of carbon nanotubes is not perfect, and the conductivity of the thin film products made of carbon nanotubes is not as good as that of ITO. Therefore, from the perspective of technology and marketization, metal grid and nano silver technology will be the protagonists of development in recent years. Metal grid technology has been applied in some PC display markets.The metal mesh technology mentioned here is a conductive metal mesh formed by pressing metal conductive materials such as silver and copper or oxides on thin film substrates such as pet. Its main advantages are low raw material cost and good folding ability. However, due to the problem of Murray interference ripple caused by yield, output and high-speed pixels, it is more suitable for desktop all-in-one computers, laptops, televisions and other products with low resolution and relatively long-distance use.Nano silver technology means that nano silver ink material is coated on pet or glass substrate, and then laser lithography is used to depict the conductive network of nano silver wire. Its main advantages are high yield, small linewidth, good conductivity and folding resistance, while its disadvantage is high cost. Moreover, compared with metal mesh, nano silver material has smaller radius of curvature and small resistance change rate during bending. In addition, due to the linewidth, it is more suitable for high-resolution close-up scenes such as mobile phones, smart watches and bracelets."By comprehensive comparison, I think nano silver has more advantages than metal grid," Huang Hanfeng said.Flexible cover plateIn order to bend at will, in addition to solving the flexible display and flexible touch, the last and most critical part is the flexible cover plate and fitting. However, due to its hard and fragile characteristics, glass cover plate is not the best choice in the field of flexibility.Huang Hanfeng said that compared with glass, pet and PI (polyimide) materials with high surface hardness and high light transmittance are better choices, but at present, pet and PI also have many problems to be solved. On the one hand, they are not resistant to high temperature and have poor light transmittance: pet and PI will have problems of partial melting and property change at low ambient temperature, and they do not have good light transmittance compared with glass.Secondly, it is difficult to achieve a balance between hardness and folding. Huang Hanfeng said that if you want to meet certain hardness requirements, you need to apply the hardened layer, but after coating the hardened layer, after repeated folding, the hardened layer will crack and reduce the hardness. Therefore, how to achieve a balance between the two is the biggest bottleneck at present.Compared with the flexible cover plate that needs further development, the 3D glass cover plate necessary for curved screen mobile phones has a very good development prospect.Some data show that 2018 may become the outbreak year of 3D glass cover plate. It is expected that the mobile phone penetration rate of 3D glass cover plate will exceed 50% around 2020. With the maturity of 3D glass cover plate processing technology and the decline of unit price, the penetration rate will further improve. It is expected that the market scale will reach more than 19 billion yuan in the future.Huang Hanfeng said that the common manufacturing processes of 1R (single radian bending) and 2R cover plates have been basically mature. They basically achieve a bending effect through hot bending technology. The difference is mainly in the coating of hardened layer. However, the yield is a problem to be solved, which is basically only 30%, and there is no room for improvement in the short term. If 4R is to be done in the future, the yield will be lower. Therefore, the yield is one of the urgent problems to be solved in the manufacture of cover plate.Flexible fitAfter the cover plate is selected, it is fitted, that is, the cover plate is integrated with the touch and display layer below to form a complete module. At present, there are two common methods: roller type and vacuum bonding: the roller has high efficiency and needs to roll the pasted object. The efficiency of vacuum type is relatively low, but it does not need to roll the pasted object, so it is not easy to cause damage to the pasted object.Huang Hanfeng said that if the curvature is large, you can only choose vacuum bonding. However, for the possible 4R bonding in the future, due to its special four side bending characteristics, it is difficult to avoid wrinkles and bubbles in places with large radians even if vacuum is adopted. At present, the industry has adopted customized extrusion airbags or plastic parts to alleviate this problem, but it has not been completely solved. Therefore, the industry still has room for progress in multi surface and high curvature fitting technology.Huang Hanfeng frankly said: "from the perspective of the supply chain, it will take several years for the flexible screen to really realize mass production. At the same time, it also needs the upstream and downstream supply chain to jointly overcome the relevant technical problems."For future development, Huang Hanfeng believes that the integration of various modules will be the general trend. He said: "in the incell technology of LCD, ITO touch film and liquid crystal layer are integrated together, which is a good integration. Now the fingerprint module is independent, and it can also be integrated with touch in the future. I think there will be a process of mutual integration and progress between functional modules in the future."
