How to Effectively Prevent Aging of LED Display Screen and What Are the Prevention Methods

By BARRY FOX For over 30 years, Barry Fox has trawled through the world's weird and wonderful patent applications, uncovering the most exciting, bizarre or even terrifying new ideas. His column, Invention, is exclusively online. Scroll down for a roundup of previous Invention articles.We could soon see a new kind of display screen from computer maker Apple - one that simultaneously takes pictures while showing images.The clever idea is to insert thousands of microscopic image sensors in-between the liquid crystal display cells in the screen. Each sensor captures its own small image, but software stitches these together to create a single, larger picture.A large LCD screen filled with image sensors would be ideal for videoconferencing, Apple suggests, as participants would always appear to look straight into the "camera". The technique could also add a camera function to a cellphone or PDA without wasting space, and light from the screen should help illuminate a subject. The more sensors there are, the wider and clearer the image. Sketches accompanying the company's patent show as many sensors as liquid crystal cells in a screen. If some of the sensors have different focal lengths, switching between them would make the screen behave like a zoom lens.Read the full patent, here.This could be bad news for under-age drinkers and anyone else trying to lie about their age.Camera maker Kodak is adapting the technology used to automatically correct flash-induced "red-eye" in digital images to determine a person's age. A patent filed by researchers from the company's labs in Rochester, New York, suggests the technique could provide a quick and easy way to check someone's date of birth.Red-eye is the effect seen when a person's open pupils allow a camera's flash light to be reflected off their retinas. Red eye correction software analyses a picture, looking for a pair of red dots in the centre of a face, and automatically dulls them to remove the effect. Kodak's patent mentions previous research suggesting a correlation between age and the way pupils react to light. As a person gets older, their pupils have greater difficulty widening to cope with dim light, it says.The company suggests that an age-verification system could take mug shots of a person from a set distance in controlled lighting, using a flash. Software would then measure the size of their red-eye dots to determine how wide their pupils are and make an estimate of their age. Although the patent doesn't say how accurate the system could be it suggests that accuracy could be boosted by automatically looking for wrinkles and grey hair in an image as well. Well, just don't point that thing at me...Read the full patent, here.Researchers from the US National Institutes of Health are working on a safer early-warning system for breast cancer. The new system would use broadcast frequency radiation instead of X-rays to detect tumours, allowing women to undergo frequent checks without exposure to hazardous ionising radiation.An array of up to a hundred mini-antennae would be built into a soft, breast-shaped sensing device. Each antenna would emit a very short burst of microwave energy, rapidly scanning across several frequencies, at just one-hundredth of the power output of an ordinary cellphone. Malignant tissue is far less conductive that normal flesh, and so should reflect much more signal back to detectors built into the same device. Software would remove random reflections from the skin surface and the patent claims that tumours as small as 1 millimetre across would show up using the scanner.Although the power is low and safe, the signal should be able to penetrate 10 cm of tissue, to reveal deeply hidden menaces. The scan should also take just one-tenth of second.Read the full patent, here.

NEW DELHI: Not contend with just reclaiming the number one spot - in terms of sales - in the Indian luxury car segment, Mercedes Benz has roared ahead by periodically adding models to its product portfolio for the country. And one particular model that has helped the Germans consolidate here has been the highly successful E Class. Little wonder then that the company this year opted to better its best and introduce the all-new 2017 Long Wheelbase Version (LWB) E Class.LWB is indeed a striking highlight of the 2017 E Class. The car has been - put absolutely simply - pulled between the wheels and now measures 3,079mm. This is a stretch of 140mm over the outgoing model - quite commendable indeed. And also quite noticeable with the sedan's side profile lending it a Maybach-ish aura. ExteriorsThe regal side profile courtesy the elongated wheelbase aside, the 2017 E Class looks every bit as royal from every other angle as well. The front grille is simplistically sophisticated - a design element which Mercedes has perfected. The grille is flanked by all-LED head lights which now feature an all-new LED DRL system. The enormous bonnet has underplayed fine lines on both ends which completes an extremely pleasing front profile. From the side, the chrome insets are quite generously visible but unlike a few cars in lower and much lower segments, it is far from being garish. The side windows are not enormous but adequate enough to ensure the cabin is adequately airy. The sudden but smooth flow back of the roofline too ensures that even the tallest of passengers won't find anything to complain in the backseat.The rear of the car once again is aesthetic with LED tail lights, twin chrome exhausts, a dash of stright-line chrome over the numberplate completing the look. Nothing is an overkill here and therein lies the charm. InteriorsThe E Class blends certain elements of the S and the C Class on the outside. Inside, there is opulence enough to take the car closer to its elder sibling rather than the younger. Yes, the new E-Class has taken the game to an all-new playing field - one which so far had cars belonging to a one-up segment. The rear of the car is really the place to be with one-push memory-function reclining seats, touch-button side and rear shades, front passenger seat position control (only for the rear-passenger on the left), one-touch sunroof and contoured leather seats fit for royalty. And of course, the elongated wheelbase makes for more rear space than one would know what to do with. Such is the level of comfort and convenience that some other features like rear AC vents, air-quality control, rear-seat center arm-rest, rear power and USB outlets seem almost too plebeian.The E-Class is usually chauffeur-driven but Mercedes has ensured the front passenger has a generous dose of luxury at his/her disposal too. Here, the first thing that commands attention is Mercedes' COMMAND infotainment system - a 12.1 inch AV interface that is truly the center of entertainment and information display. It is positioned well to keep it shaded from the Indian sun even though the vivid and bright display may have held its own under direct rays. From navigation to climate control, engine information and car performance - the infotainment system is a breeze to use and gorgeous to see. It, however, could have really been a winner had it been a touch-screen - considering the touch-screen displays are quite common in Indian cars now. Nonetheless, once accustomed to not poking at it, the display can the real ceterpiece of a masterpiece.Speaking of masterpieces, the E-Class is equipped with 13-speaker 590W Burmester system that is worthy of the ambiance that the car seeks to provide its passengers. And, if even that falls just short of expectations, there is the 64-shade ambient lighting system that is perhaps the only overkill Mercedes did in the entire package. On long night drives though, none may be found complaining as the shades change gradually using the toggle button and display screen. DriveWhile there is indeed much that Mercedes has worked on to bring about a fresh look and feel in and around the new E Class, it is the drive that truly defines any car. The new E Class may not be just any car but the drive goes an extra mile - or two - to underline its characteristics.Offered in 2.0-litre inline four-cylinder petrol, this review however focused on the extremely powerful 3-litre diesel V6 which has 255 bhp and 620 Nm of torque. Numbers may at best be indicative but the drive itself is where all of the power is truly at. Once again offered in five drive modes - Individual, Eco, Comfort, Sport and Sport , the E Class moves almost exactly as one would want it to in the selected mode. The 9G-TRONIC auto gearbox is - for the lack of a better adjective - velvety smooth while paddle shifters are present as well. The diesel motor continues to be as refined as ever and the car makes mincemeat of roads without losing its elegance. It however is important to mention that the Comfort mode could have done with a bit more punch in keeping true to the overall driving dynamics of the car. There is that marginally extra bit of pause when pushing the car forward in this mode even though the air suspensions in the car for this review made a mockery of every bump in the way.The steering remains light and nimble while not losing out on the strong feedback to keep the driver composed at triple-digit speeds which, Mercedes claims, comes up in 6.6 seconds in the diesel version.VerdictRs 69.47 lakh (ex showroom) for the E 350d, the new model is far from being inexpensive - even by Mercedes standards. The price tag though is not for nothing as here is a car that now has comfort and technological additions almost matching the pricier S Class. The passengers can hardly ask for more as they sprawl in sheer luxury. The one behind the wheel too has a lot going with a car that rides really confident despite its now elongated proportions. The competition has remained stiff with BMW 5-series and Audi A6 being very capable cars too. With the new E Class though, Mercedes has surely taken the attack to the rivals' camp and promises to come out unscathed.

The US Transportation Department has issued a rule that will require rear-view technology in many new vehicles - an effort to reduce deaths and serious injuries caused by backup accidents.The final rule issued by the National Highway Traffic Safety Administration on Monday will require new vehicles under 10,000 pounds (4,535kg) and built on-or-after May 1, 2018 to meet the new rear-visibility standards. The rule includes buses and trucks. Motorcycles and trailers are exempt.The rear-view cameras must give drivers a field of vision measuring at least 10 by 20 feet (3 by 6m) directly behind the vehicle. The system must also meet other requirements including dashboard image size, lighting conditions and display time.Reversing accidents involving light vehicles cause an average of 210 deaths and 15,000 injuries a year, and victims often include children and the elderly, the government said. Children under five years old account for 31 per cent of the deaths each year, while adults 70 years of age and older represent about 26 per cent.NHTSA said the new rule, required in the Cameron Gulbransen Kids Transportation Safety Act, will save between 13 to 15 lives per year and prevent as many as 1,125 injuries per year. The measure, signed into law in 2008, was named for a two-year-old Long Island boy whose pediatrician father backed over him in their driveway in 2002.The government estimates that a rear-view system will cost between $US132 and $US142 ($A143 and $A154) per vehicle. It will cost about $US43 to $US45 for vehicles that already have a dashboard display screen, but need upgrades to comply with the rule.Compliance will be phased in by manufacturers starting in May 2016, before it becomes mandatory two years later."Today's decision will save lives and save money for consumers," Advocates for Highway and Auto Safety President Jackie Gillan said in a statement."Every make and model will be required to meet this new safety standard and every family will benefit.

What should we pay attention to in the selection of LED display in hotel banquet hall? Generally, in the indoor environment, the screen area will exceed 3 m2. Therefore, in this case, there are three options: ordinary rear projection, DLP (digital liquid crystal rear projection) and LED display.The advantages of ordinary rear projection display screen are small pixels and high definition. The disadvantages are low brightness, small viewing angle and short lens lamp life (only a few thousand hours). DLP has the advantages of small pixel points and high definition. The disadvantage is that it has seam. At present, the minimum seam can reach 1mm. Rear projection and plasma display screens are suitable for close viewing. For Maipu Guangcai indoor LED display, the advantages are high brightness and no seam, while the disadvantages are coarse pixel particles and low definition. At present, the economic model of commercialized indoor full-color LED screen is p5p6, and other models include p3p4p7.62p8. LED display screen is suitable for indoor places with long viewing distance.When selecting LED display in banquet hall, the following aspects can be considered:1. Die. Like the outdoor full-color LED screen, it is generally recommended that the LED of the indoor full-color display screen adopt the LED encapsulated by Maipu brilliance, and the tube cores of Japan Riya and Cree of the United States are recommended for high-end products.2. Packaging form. The advantages of surface mount packaging are large viewing angle, good luminous consistency and easy automatic welding processing. It is the mainstream product of full-color screen.3. Density. Due to the large heating capacity of indoor full-color LED chip and high density of control circuit, the point density of commercial full-color screen can not be very high. Hotel Maipu Guangcai LED display manufacturer4. Drive mode. The driving mode of indoor Maipu Guangcai full-color LED screen is constant current driving and adopts dynamic scanning mode (mainly 1 / 4, 1 / 81 / 16 and other scanning modes).5. Refresh rate. Improve the refresh rate, and there is no flicker and tailing when shooting with the camera.Other considerations include the scale and brand, price, purpose, installation location and environment of LED display manufacturers. The above are some suggestions on the selection of LED display in hotel banquet hall.fqj

In recent years, small spacing LED display screen has developed rapidly, which has the trend of sweeping the whole LED display industry. After the indoor small spacing, outdoor small spacing has gradually become a market hot spot for many LED display manufacturers. Previously, the industry predicted that the market scale of outdoor small spacing LED display screen may reach 100 billion in the future. This assertion is like thunder on the ground, which makes people excited and nervous.From the new product release trends of major industry exhibitions and LED display manufacturers in the industry, the point spacing record of outdoor applications has been refreshed again and again, and all enterprises have tried their best to seize a place in the blue ocean market of outdoor small spacing. It is understood that at present, the small outdoor spacing of jrcld Jingrui Chuangxian has exceeded p2.6, and there have been corresponding application cases. At the same time, many leading screen enterprises in the industry also began to develop in the direction of small outdoor spacing. The person in charge of an industry enterprise once said that the outdoor small spacing will reopen the outdoor and semi outdoor digital Notice market that the LCD splicing screen has failed to start effectively, and will create an emerging market of nearly 20 billion yuan in the domestic outdoor / semi outdoor small advertising screen market. This shows how attractive the outdoor small spacing LED display market is!The development of small outdoor spacing to p2.5 and even P1.2 is an inevitable trend in the future. With the advent of the new retail era, the outdoor commercial display market is constantly exploding. For example, advertising machines, bus stop boards, advertising windows and other display platforms in close contact with people. If we want to achieve good interaction between the content information of LED display screen and the audience, whether P8, P6, P4 and P3 can not be satisfied, the intervention of J small spacing is inevitable.Driven by the market demand of outdoor commercial display, outdoor small spacing LED display has a considerable market development space. At the same time, with the superposition and use of screen interaction technologies such as infrared induction, face recognition, touch, 3D and VR / AR, the outdoor small spacing LED display becomes more vivid. With the support of these interaction technologies, Jingrui Chuang shows that the development prospect of outdoor small spacing LED display is very promising.Of course, there are still some technical difficulties in outdoor small spacing. For example, it is difficult to solve the problems of glue filling and plastic parts kit, and the cost of using metal kit is too high... In the second half of 2017, screen enterprises represented by a company made significant progress in cob packaging technology, Cob packaging has also become the best solution to various questionable problems in the outdoor small spacing industry. It is believed that in 2018, with the further stability and promotion of cob packaging technology, it can well help jrcld Jingrui create an outdoor small spacing market.fqj

Since the end of the year, we have obviously felt the recovery of market demand. As the LED display industry enters the traditional peak season, coupled with the continuous release of demand for high-definition video display equipment in the terminal market, especially after new display products such as mini / micro began to enable the market, the production capacity began to become the focus of upstream and downstream enterprises in the industrial chain.As we all know, China's LED display industry has been in a dominant position in the global field, and after leading for several years, China's LED display industry is further opening up its leading distance. Statistics show that with the development of high definition display market such as small spacing and Mini/Micro LED, it is estimated that the total capacity of Chinese mainland's panel will reach 55% in 2020. In addition, since this year, almost all international giants such as Europe, America and South Korea have stopped work and reduced production due to the great impact of the epidemic. Thanks to the advantages of domestic epidemic prevention and control, Chinese LED screen enterprises have seized the opportunity to expand production capacity, reduce costs and expand their leading advantages. In particular, the production capacity of mini / micro LED has become an urgent task for many led enterprises.Leyard Earlier, lyade publicly stated that the micro LED display mass production base was officially put into operation. It established a joint venture with Taiwan Jingyuan optoelectronics to set up Lijing microelectronics, the world's first micro LED display mass production base, which was also officially put into operation on October 29.ZhoumingOn November 3, Zhouming technology released information related to investor research, revealing that the industry began to pick up from Q3 and that the market continued to pick up. At the same time, on the production capacity layout of mini led, Zhouming technology disclosed that it is successively investing a large amount of funds for the upgrading of Huizhou Daya Bay industrial base as planned, and adding several Mini LED display intelligent production lines. In addition to the existing Mini LED production line, nearly 50% of the funds raised in the company's fixed growth plan will be invested in equipment in the field of mini ledTable sectionRecently, taibiao also publicly said that there are currently 9 factories in China and India, with a total of 200 SMT lines. In the mini led part, mass production is expected to start in January next year. Taibiao also invested large capital expenditure and R & D personnel.Hongli ZhihuiRecently, Hongli Zhihui announced a number of mini led investment projects. According to rough calculation, the total investment in the expansion projects announced by Hongli Zhihui this year will reach 3.65 billion yuan, and the planned annual output value will exceed 5.8 billion yuan. "As industry experts said, in the face of mini / micro led, the future display technology, China, as the most active region in the global display industry, is essential for new investment, various integration and mass production climbing of new production lines to maintain its global leading position. It is believed that with the further release of the HD display market, the investment of relevant enterprises in the mainland and Taiwan will continue to increase.Facing the upcoming Mini / micro led new display era, although China's LED display industry has leading advantages, we must also recognize our own shortcomings. Firstly, the current distribution of China's LED display industry is mainly concentrated in the southeast coastal areas. From the perspective of regional distribution, it is not conducive to the overall balanced development of the industry. Secondly, from the perspective of the overall brand pattern of the global industry, although China is in a leading position in terms of production capacity and market share, the brand influence of Chinese LED screen enterprises in the global market is still weak. Finally, there are still some weaknesses in China's LED display industry, such as relatively single technical structure and insufficient competitiveness of the whole industrial chain. In the future, we must learn from each other's strengths to make up for our weaknesses and give full play to the Industrial Synergy to continue to maintain our leading edge.Original title: [abison headlines] Mini / micro capacity demand broke out, and China's LED industry continued to leadThe source of the article: WeChat official account: LED display channel] welcome to add attention!
