Apple MacBook Air to Add Touch Screen Features? What's the New Addition of Finge 1

When it comes to sxws, most people may be confused. This little-known conference in China has a considerable influence in the United States. The full name of sxws is south by Southwest. As the world's largest and only "technology + music + film" event, sxws has witnessed the popularity of twitter, meerkat and other software.This year's sxws has been held as scheduled in Austin, Texas, USA. many technology companies have poured in one after another, hoping to become a lucky person like Twitter, and the airbar manufacturers who have appeared at the CES exhibition have also crowded into the venue of sxws.On this year's sxws, Swedish company Neonode once again took its "new product" airbar to the exhibition. The uniqueness of this product is that it can enable ordinary notebooks to have touch-screen function.

It is reported that airbar uses a patented technology that can emit an invisible light field. The light field can sense the actions from fingers, gloves and even brushes, and then convey a touch screen like experience to users. Neonode introduced that the use method of the airbar is very simple. Users do not need to install any software or add additional configuration. They just need to place the airbar at the bottom of the screen and connect it with the notebook through the USB interface.Airbar's design team said that the touch screen input accuracy deviation of this new device is between ± 2mm. When it is used to imitate common touch screen input actions, its completion can almost reach 100%. In addition, Neonode seems to have solved the problem of users' use in outdoor or other disturbing shadow environments. The company points out that they have adopted a set of optical equipment and software combination suite to enable users to have a seamless experience in the above situations.However, when airbar first appeared, it only supported new and existing chromebooks, laptops running Windows 8.1 or windows 10, and MAC devices were excluded. Now Neonode has finally brought a new model of airbar. The new model can not only turn the MacBook Air screen into a touch screen, but also support multi finger touch. At present, the company seems to be ready to mass produce airbar.

  • How to Clean a Laptop Keyboard

    In this guide, you will learn to know how to clean a laptop keyboard without removing the keys. We like to keep munching on some snacks while using our laptop and the scrapes just fall on the keyboard. They stick into the keys making it hard to type and result in uncalled for delays in work if we keep fighting with the dirty and messy keys to keep working.

    The dirt accumulated in the keys over the time also gets sticky and hinders typing, so it is necessary to have a spotlessly clean laptop keyboard. Well, this is not something too difficult if you know what to do and which tools to use. Tools Required: Here is a list of stuff that you need to clean your laptop keyboard.

    1. USB keyboard vacuum cleaner 2. Compressed air 3.

    Alcohol 4. Micro-fiber cleaning cloth Get all these tools, and then you are good to go and clean your laptop keyboard. Here is how you need to use these tools to clean the keyboard to start enjoying the experience of clean and smooth keys.

    Step 1: Shut down the laptop and get ready The first step is to shut off the laptop and remove any cables and accessories from it. This is to make sure that any moisture does not harm your laptop's functioning when you turn it on again. 1.

    Place a towel or cleaning cloth at underneath the laptop so that all the dirt and debris falls on it and you do not have to clean the surface later on too. 2. Lift one side of the laptop to tilt is so that all the dirt and mess come out of it.

    Shake it a bit to take out any loosely stuck stuff in the keys. 3. Lightly brush a cloth over the keyboard to remove any bigger dust particles that stay even after shaking it.

    You can use a USB keyboard vacuum cleaner to clean laptop keyboard as it sucks the dirt and tiny chunks of stuff stuck in the keys and sides of the keyboard. These vacuum cleaners sometimes come with LED light bulbs too which help you locate any hidden dust particles too. All you need to do is to plug the vacuum cleaner in the USB port and let it do its magic while you slowly move it around on the surface of your laptop keyboard.

    Buying a USB keyboard vacuum cleaner is necessary because you need to clean the keyboard frequently. Usually, we recommend clean it once a month. The price of the USB keyboard vacuum cleaner is around $10.

    You can buy it from eBay or Amazon. If you do not have a USB keyboard vacuum cleaner, you can use Compressed Air to clean the keyboard. 1.

    Get a compressed air can from the supermarket and insert a small straw in it. The diameter of the straw has to be small so that the air comes out with greater pressure. 2.

    Release the air from a compressed air can result in short swift bursts to let the sticky stuff come out of the keys. It is better to direct the outlet of straw at the sides of keys to have a better and thorough cleaning. 3.

    This works even better if you tilt your laptop to a side and then treat the keys with compressed air from the can as it gets better access to tiny particles this way. Since you have removed all the visible impurities, it is time to clean off the ultra-small particles too. For this, a soft microfiber cloth is perfect since it lets the particles get adsorbed on its surface leaving the keyboard free of any pollutants.

    Just sprinkle a small amount of water on the microfiber cloth and its adhesive capacity will improve even more. Remember to sprinkle just a little bit of water as excessive water will seep in through the sides of the keys and cause harm to your laptop. A clean laptop keyboard not only has to be free of all the dust particles but also bacteria and other microorganisms.

    Soak some cotton in a solution of diluted alcohol and then drench it completely. After that gently rub the cotton over the surface of the keyboard and ta-da the keyboard is as good as new! Make sure that you follow these steps thoroughly, and you will be amazed by the clean and spotless surface of the keyboard that you will eventually get!

Apple Will Develop Display Screen and Develop the next Generation Microled on a Large Scale
Apple Will Develop Display Screen and Develop the next Generation Microled on a Large Scale
IPhone x is Apple's first mobile phone with OLED screen, and the screen of this mobile phone is provided by Apple's competitor Samsung, but this situation may change in the future.San Francisco - March 19, according to a reporter's report, Apple will independently design and produce its device display for the first time, and use the secret facilities near the California headquarters to produce a small number of screens for testing purposes.Apple hopes on the microled screen, which is different from OLED. The luminous compounds it uses are expected to make future devices thinner, clearer and more energy-saving. Apple is currently investing in the development of the next generation of microled displays.However, the production of microled screen is much more difficult than OLED. People familiar with the matter said that Apple almost gave up the project about a year ago, but the engineers made progress later, and the project was further developed. However, consumers may have to wait a few more years to see the research and development results.People familiar with the matter said that the scale of Apple's California factory can not meet the requirements of mass production, but the company hopes to prevent partners from obtaining this technology in the short term, and keep everything confidential in the development stage.The screen suppliers of iPhone come from manufacturers such as Samsung, Japan display and LG display. Apple's independent research and development of display components may turn these partners into competitors. However, mastering microled technology will also make apple stand out in the increasingly mature smartphone market.These insiders, who asked to remain anonymous because of the discussion of internal planning, said Apple was investing heavily in the development of the next generation of microled displays. The light-emitting compounds used by microleds are different from the current OLED displays, which is expected to make future devices thinner, clearer and more energy-saving.People familiar with the matter said that the production difficulty of this screen is much higher than the OLED display currently used. The company almost gave up the project about a year ago, but engineers made progress later. The technology has entered the later stage, but consumers may need to wait a few more years to see the results.This ambitious undertaking is the latest example of Apple's internalization of key component design. For several years, Apple has been independently developing chips to power mobile devices. In the long run, the R & D of display may hurt a series of current suppliers, such as display manufacturers Samsung, Japan display, sharp and LG display, and human-computer interface solution provider Synaptics. It could also hurt universal display Corp., a leading OLED technology developer.Mastering microled technology will help Apple stand out in the increasingly mature smartphone market and surpass rivals such as Samsung, which claims to have an excellent display screen. Ray soneira, who runs display mate technologies, a screen testing company, said that internal screen design was a "golden opportunity" for apple. "Everyone can buy an OLED or LCD screen," he said. "But apple can have microleds."None of this is easy. Mass production of new screens requires new production equipment. By the time this technology is ready, there may be other alternative technologies. Apple may encounter insurmountable obstacles and abandon or postpone the project. In addition, the investment in this project is also very high.Eventually, Apple may outsource the production of the new screen to minimize the risk of production chaos to its profits. A person familiar with the matter said that the scale of the California plant could not meet the mass production requirements, but the company would hope to prevent partners from obtaining the patented technology for as long as possible. "We invested a lot of money in the factory," the person said. "The scale of the factory is large enough to complete the engineering design. In the development stage, we should keep everything confidential."
What Is an OLED Display? This Article Teaches You to Understand the Difference Between LED Backlight
What Is an OLED Display? This Article Teaches You to Understand the Difference Between LED Backlight
LED backlight refers to the use of LED (light emitting diode) as the backlight of LCD, while LED backlight display is only the backlight source of LCD, which is transferred from traditional CCFL cold light tube (similar to fluorescent lamp) to LED (light emitting diode). The imaging principle of liquid crystal can be simply understood as that when the external voltage is applied to deflect the liquid crystal molecules, it will block the transmittance of the light emitted by the backlight like a gate, and then project the light into the color filters of different colors to form an image.The transition of backlight module from CCFL to LED can bring many benefits, which can make the brightness of the display screen more uniform, the product power consumption is lower, and the shape can be lighter and fashionable. However, w-led (white LED) backlight is widely used in the market. In fact, this backlight only replaces the luminous components, and the improvement of display effect is very weak or even not improved. Rgb-led (three color LED), which has significantly improved the display effect of LCD products, has significantly improved the display effect, but at the same time, the production cost is high, so it is applied to high-priced LCD TVs. At present, the LED display mentioned by businessmen refers to the display products with white LED backlight. The difference between it and ordinary LCD is the change of backlight.LED display screen integrates microelectronics technology, computer technology and information processing. It has become the most advantageous public display media with its advantages of bright color, wide dynamic range, high brightness, long service life, stable and reliable operation. At present, LED display screen has been widely used in large squares, commercial advertisements, stadiums, information dissemination, news release, securities trading, etc, It can meet the needs of different environments.LED display is a display mode by controlling semiconductor light-emitting diodes. Its general appearance is composed of many usually red light-emitting diodes, which display characters by turning on and off the lights. A display screen used to display text, graphics, images, animation, market, video, video signals and other information.OLED display is considered as the emerging application technology of the next generation of flat panel display because of its excellent characteristics such as self illumination, no backlight, high contrast, thin thickness, wide viewing angle, fast response speed, flexible panel, wide temperature range, simple structure and process.OLED is the abbreviation of organic light emitting diode, which is translated as organic light emitting diode or organic light emitting display. In fact, this luminescence principle was discovered as early as 1936, but it was not until Kodak launched OLED double-layer device in 1987 that OLED attracted people's attention as a commercializable and excellent flat panel display technology. At present, more than 100 research units and enterprises around the world have invested in the R & D and production of OLEDs, including display giants in the current market, such as Samsung, LG, Philips, Sony and so on. On the whole, the industrialization of OLED has begun, in which monochrome, multicolor and color devices have reached the level of mass production, and large-size full-color devices are still in the research and development stage, but the production capacity is still low.Many netizens are easy to associate OLED with the LED backlight hyped by current manufacturers. In fact, OLED and LED backlight are completely different display technologies. OLED emits light by driving the organic film itself through current. The light can be monochrome such as red, green, blue and white, and can also achieve full-color effect. Therefore, OLED is a new luminous principle different from CRT, led and liquid crystal technology.The LED display screen is composed of LED dot matrix and ledpc panel. The text, picture, animation and video can be displayed by turning on and off the red, blue, white and green LED lights. The content can be changed at any time. All components are display devices with modular structure. The traditional LED display screen is usually composed of display module, control system and power supply system. The display module is composed of a dot matrix composed of LED lamps, which is responsible for luminous display; By controlling the lighting of the corresponding area, the control system can make the screen display text, pictures, videos and other contents. Monochrome and two-color screens are mainly used to play text. The full-color LED display can not only play text, pictures, animation, but also play video and other formats.At present, it is widely used in every corner of the world because of its wide audience area, simple operation, long service life, energy conservation and environmental protection. In general, LED display, LED backlight and OLED are three completely different imaging technologies.

I think it's under personalize on Vista and 7.3. Where can I get a display screen with 30 Hz or less refresh rate? [closed]The information you are referring to is outdated. Flickering, banding, and other artifacts caused by refresh rate issues is primarily seen on CRT monitors -- LCDs are largely unaffected.If you want to reproduce this issue intentionally for the purposes of an experiment, you will probably need to find an old CRT monitor. The effects created by a monitor of this type cannot be reproduced accurately on an LCD4. My iMacs Display Screen Fell downYou have two distinct problems with your iMac that you are unfortunately conflating with the most obvious damage - the broken display. The display is most likely broken and will need to be replaced. I can be tested, but not in a typical home or office environment. The cable connectors on the logic board may be damaged as a fall like that will literally rip them off the board. A visual inspection should be enough to verify if they are good or notThe fan spin is likely because you replaced your hard disk with a non-Apple one that does not have a temp sensor. A missing sensor will cause the fans to spin at full speedThe slow performance is likely due to the erroneous temp readings (from the missing sensor) and the Mac thermal throttling in response. To fix the fan and speed issue, you simply need an inline temp sensor to send the correct data to the SMC. However, the screen is quite expensive and you should get a quote on a replacement prior to doing this - it may be much more cost effective purchase a replacement iMac of the same vintage and sell that one for "parts."Also, if you are going to replace a HDD and go through all the trouble on an iMac, you should spring for an SSD. The performance gains are well worth it5. My 1st generation iPod display screen is partially blank.

Design and Implementation of LED Multifunctional Remote Control Display Screen
Design and Implementation of LED Multifunctional Remote Control Display Screen
The LED multi-function display system adopts the method of dynamic scanning, takes STC89C58RD single chip microcomputer as the main control chip, and uses the self-made infrared remote controller to wirelessly download information to the host for display. The display screen is 16 & times composed of 1024 bright red photodiodes; The row scanning circuit is driven by 74hc154 decoder chip, the column scanning circuit is driven by 8 74HC595, and the infrared remote control transmitter adopts integrated infrared transceiver. The system realizes digital. letter. The dynamic and static display of Chinese characters and other information can update the display information through serial communication with PC. the system can also remotely move the information up, down, left and right and update the display content through the remote control keyboard.With the development of computer and related microelectronics. With the rapid development of optoelectronic technology, LED display has high reliability. Long service life. Strong adaptability to the environment. With the characteristics of high cost performance, it has rapidly grown into the mainstream product of flat panel display.At present, most LED dot matrix display systems have their own font library, and the realization of display and dynamic effect (mainly the rolling of display content) depends on hardware scanning drive. Although this method is more convenient, the display content is not easy to update in time, and when the LED display is installed outdoors, it can not be effectively controlled. The indoor display screen is controlled through the data line, which is very inconvenient.The design is carried out around the multi-functional LED display screen. The display mode moves up, down, left and right. The display content is controlled and updated in real time by PC. The system uses infrared emission. The remote control receiver completes the whole infrared remote control transmission by receiving and identifying the infrared light and judging the control operation. The receiving process can easily update the display content and change the display mode, making the design more practical and convenient for operation control.1. Overall design schemeMost LED displays adopt dynamic scanning display mode. The principle of scanning display is based on the visual persistence of human eyes. Each display row (column) is displayed in turn. As long as the refresh rate is not less than 24 f / s, human eyes will feel a complete and continuous image.Infrared remote control uses infrared as the carrier to transmit control information. The infrared emitter adopts infrared light-emitting diode, so the remote control transmitter is easy to miniaturize and cheap. Using digital signal coding and secondary modulation can not only realize the control of multi-channel information, increase the remote control function, improve the anti-interference of signal transmission and reduce misoperation, but also have low power consumption, no signal crosstalk, fast response speed, high transmission efficiency, stable and reliable operation, etc. The single chip microcomputer adopts STC89C58RD , the amount of data stored is larger than STC89C52, and the crystal oscillator uses 22.1148 MHz to improve the refresh frequency and make the display more stable. After the output line signal of port P0 is decoded by 74hc154, the line strobe signal is generated and sent to the line of the display screen for display in turn. The P2 port of the single chip microcomputer is connected with the 8-bit shift register 74HC595. The overall structure of the system is shown in Figure 1.2 hardware circuit design2.1 16&TImes; 64 LED dot matrix screenThe system display screen is made of 16 rows and 64 columns of bright white 5 mm LED red photodiodes. The anodes of 64 LEDs in each row are connected into row lines and led out, and 16 interfaces in 16 rows are used as the interface end of common row lines, which is convenient to connect with the row drive module to realize row positioning and scanning; The cathodes of 16 LEDs in each column are connected and led out, and each 8 column lines form an interface, which is convenient to connect with the column drive module to realize the storage and scanning of register data, so as to build the display screen system. Some dot matrix screen circuits are shown in Figure 2.2.2 main control and scanning driving circuitThe main control circuit takes STC89C58RD chip as the core and external reset circuit. Clock circuit and serial port download line interface circuit (RS 232 communication interface) are used for the communication between LED display system and computer. The communication mode is 10 bit asynchronous communication. Online download is convenient for program update and system maintenance.The scanning driving circuit is composed of row and column drivers. There are 16 rows of LED display screen. A piece of 74hc154 is used to decode and select the 16 rows of LED, which is amplified by TIP127 and converted to high level, so as to select the traffic line.The column scanning drive adopts the scheme of parallel data serial transmission. The data latch is 74hc595.64 and the column is driven by 8 74HC595 chips. The 8 74HC595 are connected end to end. The shift output of the previous 74HC595 is connected to the input of the next 74HC595. The serial data input end of the first 74HC595 is connected to the data output end of the single chip microcomputer. The first 2 74HC595 are connected as shown in Figure 3.2.3 infrared transceiver remote control circuitThe principle of infrared transmitting and receiving is: the input signal at the transmitting end is amplified and sent to the infrared transmitting tube for transmission. At the receiving end, after the receiving tube receives the infrared signal, it is amplified by the amplifier and restored to the control signal. Press a key, the single chip microcomputer recognizes the key, and the single chip microcomputer sends a pulse of a certain frequency to the port connected with the infrared transmitting tube. The pulse is modulated with a carrier pulse of about 38 kHz, and then the modulated pulse is buffered and amplified to excite the infrared led to convert electric energy into light energy, so that the infrared LED emits infrared of a certain frequency. When the receiving control system receives the infrared light, the frequency of the infrared light is obtained by the timing / counter in the single chip microcomputer, and then the frequency is sent to the CPU. The CPU decodes the signal and identifies the control signal, so as to implement the control function of the control circuit and complete the whole remote control function.The system adopts the integrated infrared receiver HS0038, as shown in Figure 4. Pin 1 GND is connected to the power ground, pin 2 VCC is connected to 5V, and pin 3 out is the data output terminal (TTL level, inverse output), which can be directly connected with the single chip microcomputer.Se303 is an infrared emitting diode. When p2.0 = 1, triode 9013 is turned on, and se303 is powered on to emit infrared. In fact, it emits a pulse train with a frequency of 38 kHz. The circuit connection is shown in Figure 4.
What Does the Laptop Screen Flash Mean
What Does the Laptop Screen Flash Mean
Hello, will using LCD for a long time affect the notebook screen? When using the LCD screen, pay special attention to its working time. When it works continuously at full load for more than 96 hours, it will age rapidly and even burn out in serious cases, resulting in huge economic losses to users. This is because the pixel points of the LCD screen are composed of liquid crystals. Working for a long time, it is easy to overheat some pixel dots. Once the limit is exceeded, it will cause permanent damage. This forms what is often called a "bad spot" (some media call it a "black spot"). Therefore, if the user has to work for a long time, the screen must be intermittently rested, and the same content cannot be displayed for a long time. When the screen is waiting to work, it is necessary to reduce the brightness. Using screen saver is a good habit. It can not only delay the aging of LCD screen and prolong its service life, but also avoid hardware damage.   If there is something wrong with my screen, can I take it apart? For the LCD screen, because its structure is very delicate, no matter what problem occurs to the user's screen, do not disassemble the LCD screen by yourself. If you suspect that your LCD screen is not working properly, you should ask the manufacturer to send professional eyes to help solve the problem. The transformer in the LCD background lighting assembly may still carry 1000V high voltage (although it is micro current) after shutdown for a certain time. If non professionals do not handle it well, it may cause new faults of the assembly, and in serious cases, it may also cause the screen to permanently fail to work - this is an unwise move to lose money for small things.   Hello, how can I prevent the laptop screen from aging? The lighting lamp in the LCD screen is the only natural consumption part. After a long time of use, it will age, resulting in the darkening of the screen and the decrease of brightness. If the screen darkens due to aging, you only need to replace the lighting lamp to bring the screen back to life and return to youth. Of course, the most important thing is to pay attention to maintenance at ordinary times. Prevention lies in the future. Based on the author's years of experience in screen maintenance, users can pay attention to some problems: for example, the brightness cannot be adjusted too high, and long-term high load work will accelerate the aging of the screen   Excuse me, do different flashing modes of LCD screen have different meanings? Due to the influence of the analog signal output interface, for example, the clock and phase of the pixel are not synchronized with the analog signal output, which will lead to flicker. This phenomenon is usually called pixel jitter. It is an occasional flicker phenomenon, which is inevitable in the process of analog / digital conversion. In order to solve this kind of problem, there are two methods. It can be "automatically adjusted". There is a "automatic setting" function on the LCD screen, which is used to adjust the LCD screen to the best state after analyzing the input signal. It can also be "manually adjusted", which can be adjusted by two functions: phase and clockHello, the weather is very bad recently. It's wet all around. Does it have any impact on the laptop screen? Dampness is the taboo of LCD screen. When using LCD screen, it must be placed in a ventilated and dry environment to avoid the invasion of water vapor. This is because the internal design of LCD screen is very precise. Once there is short circuit caused by oxidation and corrosion due to humidity, it will bring huge economic losses to users. If you accidentally wet the screen, don't panic and turn off the power first. If there is only moisture on the screen surface, wipe it gently with a soft cloth, and then turn on the power to work. If the moisture has entered the LCD screen, you must put the LCD in a well ventilated or warm place to let its moisture evaporate. If the situation is very serious, users should ask professionals to help solve it. Remember, first of all, turn off the power supply and do not let the LCD power on when the moisture is not removed, otherwise it will easily lead to the corrosion of the LCD electrode, and the best technicians will have no way to recover.

This would correspond to a black screen with a small white spot. By moving this white spot around the black screen and measuring the voltage at the backlight LEDs, some amount of spacial detail could be recovered (depending on the physical dimensions of the screen and the depth of the liquid crystal layer). The size and thickness of the spot will cause light rays to be rejected by angle based on the spot position.The minimum transmission area will be limited by the total amount of light transmitted by the black pixels, so your resolution will effectively be limited by the screen's contrast ratio as the white spot must be large enough to transmit more light than the black pixels over most of the screen.This would only be suitable for taking still images due to the time required to capture one frame, but the necessary mask frames could be hidden between frames during the display of a normal video on the screen.Can camerasdisplay screens with window/mirror-like optical behaviour exist?Transmitting each individual photon is infeasible, given the amount of computation that would be required, but technology for capturing some information about incoming light direction already exists and is used in the Lytro "light field" camera.The corresponding light field display does not exist, as far as I am aware.

Apple May Release a New Screen Fingerprint Technology Patent in 2020
Apple May Release a New Screen Fingerprint Technology Patent in 2020
(source: Keke house)Whether it is the functional computer era more than ten years ago, the current smartphone era, or the 5g era that is about to enter, the security of devices has always been a hot topic. The iPhone x launched by Apple two years ago won the hearts of many fruit fans with its unique ID design. It is from this generation of iPhone that the home key used for many years disappeared. At the same time, fingerprint identification is also a stranger to Apple's mobile phone, and "face ID" has replaced it and become the symbol of the new iPhone.Compared with apple, some Android phones have found the best of both worlds in recent years. Among them, Xiaomi digital series and Huawei mate series are not only equipped with 3D face recognition technology equivalent to the security of face ID, but also place the continued fingerprint recognition function at the bottom of the screen. BOE's breakthrough in LCD screen fingerprint technology makes screen fingerprint identification no longer the "patent" of OLED.Although the face ID unlocking method has higher security, through the survey of some users, more than 65% of users think that fingerprint unlocking is more attractive to them, because fingerprint unlocking is more convenient than face unlocking. However, more than 90% of users want the mobile phone to support both face and fingerprint unlocking methods. The reason is like what toy Dragon said, "I can't use it, but you can't do without it".But the new iPhone released by apple in the past two years has always adhered to face ID, just like a boyfriend who has entered the sage mode, without mentioning fingerprint identification. Recently, it was reported that apple is studying a full screen fingerprint recognition scheme. If this technology is mature, fingerprint recognition will return to the iPhone.
Corning Brings Gorilla NBT Glass to Touch Screen Laptop
Corning Brings Gorilla NBT Glass to Touch Screen Laptop
key word:Corning, touch screen, notebookThe new protective glass helps to prevent damage to the touch screen; Corning gorilla glass enters new marketsCorning gorilla glass NBT, the latest protective glass launched by Corning today, aims to protect the touch screen laptop display from scratches and other damages caused by daily use.Gorilla NBT glass is a unique screen protection solution launched by Corning for touch screen laptops. Touch has become the main way of interaction between users and devices, and with the increase of touch interaction, the potential risk of glass scratch is also increasing. When these equipment are in intensive use every day, scratches will lead to the breakage of protective glass. Corning gorilla NBT glass has stronger scratch resistance. In case of scratch, the scratch visibility is smaller and the residual strength is higher, which can prevent the damage of notebook computer display when using sodium calcium glass with poor performance.Consumers pursue thinner, smoother and lighter personal computers with touch function. The market research conducted by market research institutions on the next wave of touch technology shows that in the next few years, in terms of protecting the glass market, laptops with touch function may reach the market share of smart phones. Corning gorilla NBT glass brings the world's leading protective glass solution with low cost, scratch and damage resistance expected by consumers to this new mobile device market."As the preferred protective glass for global equipment manufacturers, Corning gorilla glass has now entered the emerging touch screen notebook computer market with its special performance," said James R. Steiner, senior vice president and general manager of Corning special materials department. "As the demand for touch screen laptops continues to grow, we believe Corning gorilla NBT glass can challenge the current performance of soda lime glass, and its scratch resistance is 8-10 times that of soda lime glass. In fact, customers can now get the best protection glass solution at only 1% to 2% of the retail price of a laptop, which comes from gorilla Solution. In short, we believe that if you don't use gorilla glass on your device, it's not good enough. "Similar to handheld devices or tablet devices, consumers' physical contact with touch screen laptops includes tapping, tapping, grasping and cleaning. These interactions with laptop devices every day may cause scratches on the protective glass and affect the user experience. Corning consumer survey shows that the complaint rate of scratched laptop screens is more than four times higher than that of other mobile devices. Changing the screen can be very expensive, sometimes as much as half the price of the entire laptop, and users have to wait a few days."As a leader in touch computers, Dell is always looking for the best materials to ensure that our laptop screens can resist collision and scratch," said Sam Burd, vice president of Dell PC products group. "We used Corning gorilla NBT glass in the new client device to be launched this fall, which further strengthened the reliability and durability of our products to maintain the leading position in the industry."Corning gorilla NBT glass is now available and is expected to be applied to several notebook products of several world leading computer brands later this year.For more information about Corning gorilla NBT glass, please visit.
