Accumulation Technology General Manager Chen Qikai from the "change" began to talk about the past decade led display industry after a substantial market and environmental changes. The first stage, 2008 to 2013 for the outdoor led display of the glorious period, from the 2008 Beijing Olympic Games and the 2010 Shanghai World Expo, see the Chinese led display market has a global indicator of performance. SONY introduced the first LED TV in 2012, LED outdoor display will be introduced to the indoor application, led led display into the second stage. From 2013 to 2017 is the period of vigorous development of indoor LED display, we can see led display towards the direction of micro-pitch development, accumulation of science and technology in response to market demand, the development of the corresponding driver IC and seven problem-solving solutions, such as by the market Welcome to the Hawkeye series. When the P2.5 standard screen appears, the small pitch has begun to enter the Red Sea competition, so the small gap display new challenges will focus on the implementation of P1.0 points below the point spacing requirements. It can be seen that the first market focus is micro-LED technology, has been expected in the future can be achieved in smart devices, wearable products or the expansion of reality, virtual reality applications, and we are about to achieve the goal is to micro -LED technology is applied on a small pitch display. The second focus is on the display and the Internet of things to do with the interaction between the people and the display of the increasingly frequent, you can capture the flow of people through the behavior patterns and data analysis to create new industrial value, these two key points will be opened Innovative business models and challenges.
In recent years, the application of virtual and expansion of the reality of the gradual popularization, BlueWater Technologies is the United States led display audio and video integration leader, is committed to the virtual / expansion of the reality and led display to be integrated to provide a complete immersive audio and video Space concept. Product development, deputy general manager Doug Wack to share with us two led display in the virtual / expansion of practical applications on the reality. The first is to cast virtual reality, in a space within the wall connected to each other to form a virtual reality led display carrier, the viewer can see the same space in the same dimension of the virtual screen presentation; the second is a three-dimensional surround Virtual reality, in the ceiling, the floor and the walls set up led display, the recorded environment will be reproduced in the led display built by the virtual environment space. The distance between the viewer and the display is only one step away, so the brightness of the led display will be very low, especially in the low gray time, the refresh rate and gray scale will have harsh requirements, it is very popular with accumulation technology Proposed Hawkeye program.
In view of the led display a substantial increase in specifications, customer quality and product reliability requirements more stringent. OSRAM Opto Semiconductors (China) Co., Ltd. Visible LED market manager Liang Zechun said, led display application four challenges include reliability, aesthetics, energy and price. LED display failure, including the appearance of deformation, color, brightness attenuation, color shift, dead light dead spots and other issues. OSRAM for outdoor and indoor LED display made a different test methods and standards, thereby enhancing the reliability of LED lamp beads. At present, OSRAM corresponds to the small pitch display LED packaging products, introduced in 2014 1010 package, and indoor small spacing using 0808 LED package has been listed in 2016, this year also introduced high brightness contrast outdoor application 2828 package. The last show in the New York Times Square Marriott (Marriot) hotel, the world's largest 4K led display is the use of accumulation of technology Eagle Eye IC program of global success stories.
In addition to the LED quality to do effective monitoring, so that the display of the visual effects even better, the controller can also be used with more yuan solution. Brompton Technology Ltd. from London, UK, is a controller vendor specializing in the development of the rental market and providing complete engineering solutions. Brompton Technology Ltd.'s led display controller project manager Elijah Ebo mentioned three distinctive controller functions. The first is OSCA (On Screen Color Adjustment), can be produced at different points in time led by the production of color display uneven, adjusted to a consistent color. The second is the color effect change (Chroma Tune), can replace or adjust the color of any image on the screen, and will not affect the color of other areas of performance. The last feature is Dark Magic, which allows the gray resolution of the screen to reach 26 bits through the controller. The function of the above controller has been synchronized with the accumulation of the Hawkeye IC program to do with.
And the next generation of display technology is expected to lead the trend of micro-LED, the accumulation of micro-LED products business unit director Huang Bingkai said that the application of the display will be more diversified development, including the surface screen, smart wear device, micro- LED display, virtual or expanded real-life experience, interactive display applications. The micro-LED display technology from the epitaxy, luminous efficiency to transfer technology, will be a new challenge. Director Huang also specifically mentioned that in the micro-LED manufacturing process, reducing the packaging steps, so the LED viewing angle will be more broad, brightness contrast is also improved, showing a better display, but the epitaxial process in the epitaxy chip wavelength Error control <± 2nm, to reduce the loss of picking grain and improve production efficiency; while the chip size is too small will also affect the efficiency of these are the chip technology to continue to improve the place.
In addition, the huge amount of transfer technology, including SONY using laser cauterization, APPLE mining LuxVue electrostatic adsorption, Hon Hai to eLux fluid phase change. In the process of transfer caused by the loss of light or dead lights, detection and repair program to use the circuit to prevent product failure. If the cost of the huge amount of transfer to overcome the problem, the cost of the lamp can be reduced by 82%, the overall cost can be reduced by 32%, the fastest expected next year micro-LED can be used in the indoor ultra-small pitch display market.
micro-LED topic continued fever, the corresponding driver IC MBI5359 is a major highlight of the whole seminar. Accumulation technology led display product director Luo compassion analysis, for ultra-high pixel density P1.0 the following display, Hawkeye 300 MBI5359 is a new generation of high integration drive program is micro-LED's first solution. MBI5359 has four major features: small package size, the new three high (high integration, high gray, high refresh), modular layout and early perception LED failure.
When the distance between the LED display is getting smaller and smaller, the high integration IC brings the size of the package to reduce the number of parts and components to help reduce the space and cost of PCB board, and modular layout can accelerate the time to market products; Picture quality improvement, high integration driver IC is currently on the market the first driver IC can be more than eight lines in the performance of the original 16bit gray scale technology, so the screen contrast greatly improved and in the low gray performance more delicate; high refresh rate But also to make the dark screen shows better stability does not flicker, compared to other programs on the market, low ash refresh rate is higher. Luo Director also specifically mentioned MBI5359 with early warning LED failure function, the display manufacturers in the burn machine is completed, you can do for each pixel detection, will be the failure of the pixels for maintenance, thereby enhancing the quality of the product. In addition, MBI5359 also extended Eagle Eye 200 intelligent power-saving features, energy-saving effect of more than 25%, so this high-integrated driver IC is not only to provide a new solution manufacturers display, but also to meet the increasingly stringent use of end customers demand.
In the general control system, Xi'an Nova vice president of electronic technology, said He Guojing, display technology, the ultimate goal is to let the viewer has the experience of immersive, a good display device in addition to the hardware appearance of the aesthetic, the most important Is the application of internal software and coordination functions. Including spatial resolution, gray scale resolution, color gamut range, brightness dynamic range, time resolution five indicators. Among them, the gray scale resolution, there are two reasons for the existence of pseudo-contours of the gradient screen, respectively, for the video source gray scale and display gray scale, Nova through support for high gray-scale input, the gray-scale resolution Increased to 18bit, in order to overcome the lack of gray-scale problems caused by the screen.
Finally, by the letter of the total manager of the photoelectric Li Yaping review lecturers wonderful speech content, summed up in the future led display demand will be added to the value of the product-oriented, whether it is equipped with Internet of things to produce new applications, or micro- LED technology to create a new pattern, will bring new industries to the weather. Accumulation technology to subvert the ultra-small spacing display technology, and the industry in the middle and lower reaches of the common market trends and challenges, and work together to create the next generation of industrial ecology.
