The 2015 Accumulation Technology Display International Symposium was grandly launched at Shangri-La Hotel, Shenzhen. This time, an equation: dt= LED display value for the next 5 years, runs through the main axis of the seminar to explore the general trend for the overall LED display industry. Exponential growth, how to adapt to the trend and grasp the trend early is also the accumulation of technology hopes to share and discuss with all industry friends through the platform of the seminar.
Yang Lichang, chairman of Accumulation Technology, mentioned in the opening speech that the importance of the trend to the company lies in the fact that the trend is the first step to grasp the business opportunities. He suggested that after the rise of the commercial mode of online video downloading, the record industry could not make money by selling CDs, instead it was the singer's singing activities, which led to the development of the LED rental industry. Therefore, in the face of such a trend of urbanization, the opportunity for the LED display industry will be brought to an in-depth discussion. Finally, at the end, Chairman Yang mentioned that the large-area display in the room will quickly become the mainstream. The LED small-pitch display has a comparative advantage over the DLP and rear-projection schemes, but there are still some problems that require a breakthrough in the upstream and downstream of the industry chain. The LED small pitch display is introduced into the room to show the speed of this market.
George E. Ray, R&D Director of LMG, a US leasing company, shared the dynamics of the US leasing market. George first mentioned that LMG was an audio-visual system integrator founded in Orlando, USA in 1984. In 2008, it began to introduce LED display products and increased usage every year. In the business group, it can be divided into exhibitions, tour concerts and overall system integration. The choice of LED display will be different. The common point is that all products can be used for more than 10 years, and the use of shaped screens. It is a large group in the LMG business group. Different from other suppliers, LMG has its own R&D and FAE team, which can provide support 24 hours a day to meet customer needs. LMG's success stories range from Madonna's 2010 Super Bowl midfield show, One Direction's US tour, and Disney's company system integration. In the past few years, the use of LED displays still has some incomprehensible problems, including the moiré generated during photography, rental screens, because of the need for transportation and installation, the need for a more robust design and the requirements of customers. Curvature, integral RF/EMI solutions, anti-UV for outdoor use must also be considered, and color display must be consistent. Finally, for the demand of products in the US leasing market, George mentioned that there are certain markets for low-priced and high-priced products. The demand for high-priced products will be toward high resolution such as 4K display effect or 3D direction, but overall it is reliable due to long-term use. Degree is a constant requirement, especially for the rental market. The design of the box structure and the creativity of the shaped screen are all valued and influence the creativity of the stage design.
When it comes to the manufacture of LED displays, the cost of LED lights accounts for more than 50%, and its importance is known. If you are concerned about the evolution of LED packaging for small-pitch display, you must not mention Everlight. This time, Everlight Electronics Jin Haitao collaborated to cut into small-pitch LED lamp packages from the perspective of past, present and future. According to LEDinside and IMS data, Everlight Electronics is currently the sixth largest packaging plant in the world, and its monthly production capacity will increase from 4,400 KK to 5,500 KK in 2014. Jin Associated mentioned that Everlight Electronics entered the display market in 2000 and introduced the 1616 package. As the industry wave moves toward small dots, the package of Everlight Electronics is also synchronized and ahead of the industry. From 2010 1010 package to 2015 0505 package, 2016 is expected to launch 0404 package, which shows the mastery of the industry. Just to make the product small and not enough to show the efforts of billion light, in the package appearance material from the first generation of transparent plane stamping to the current black matte surface, adhere to the pure gold line process, in order to achieve the highest level of reliability. For the quality of the insistence, the product must pass the anti-UV test and waterproof test before leaving the factory, to achieve the so-called aerospace-grade anti-UV specifications and brightness degradation ratio below 5%. In addition to the small-pitch LED package products, Infrared products are the world's number one, with a market share of 23%. Therefore, in the future, Jin Xieli mentioned infrared photoelectric touch technology, which is the thinking that everyone can jump off the LED display, and think about how LED display can increase interaction with the audience, in the Internet of Things and the Internet. The times create opportunities to win.
When the director of Nova Heguo talked about the smart display, he broke the question in the first time and discussed how to make the LED display more intelligent from the perspective of experience. It takes a lot of effort to illuminate a display. Before the Nova MCTRL660, you need to operate more than 150 pages, 200 buttons, and 4,000 options, but in fact, you don’t need such a complicated system during the actual performance. Therefore, the MCTRL660 uses four steps to make the display operation no longer remote in a straightforward and simple way. The birth of such a product represents Nova's position in the user experience to think about product development. From 2011, two more sending cards are needed to light up the 1920*1200 display period, and now the video processor has been integrated, and even With the SmartLCT function, even the operation of the shaped screen is quite simple, as well as hot backup, arbitrary card replacement, etc., incorporating the concept of intelligence into the user experience. Under the structure of the Internet, the remote management of the display screen is more flexible. NovaCloud can be operated by mobile phone, computer or tablet on Android or ISO interface. It can be easily operated and monitored by the monitoring system to provide quick data usage and data analysis. In the final summary, Director He summarized the intelligent display as a smart experience: "With the intelligence of people to make the display smart, let the display become a happy experience, the display will be more convenient to control and apply, more comprehensive monitoring And protection, deeper insight and analysis."
The first wave of the second half was kicked off by Mr. Li Yaping, the general manager of Juxin Optoelectronics, and the industry was boosted by the “MBI5124 reloading strong upgradeâ€. Compared with the general-purpose IC, the MBI5124 has DPWM technology, which can effectively improve the utilization rate to 95%, and the performance in refresh and grayscale is also better. In particular, the current industry is popular in the outdoor use of surface mount SMD lamps, with MBI5124 as the driving core, it will be able to solve the problem of insufficient brightness of outdoor surface stickers. Accumulation also proposed a strong upgrade program, which is expected to prompt the rapid introduction of MBI5124 into the outdoor surface mount market, triggering a revolutionary development in the outdoor display market.
The birth of the Hawkeye solution platform is another highlight of the seminar. The CEO of the accumulation technology, Mr. Chen Qikai, led the guests to enter the Hawkeye solution platform. General Manager Chen Qikai mentioned: "In the previous period, we reloaded and upgraded. In essence, we tried to change the industry's expectation for the basic models and redefine the basic chips." When accumulating design chips, the most common point is that we can What kind of innovation is brought to the customer and what kind of pain point the customer can solve. After entering the field of multi-scanning of small dots, it is more well known that the realization of many functions is not only the chip itself, so the peripheral IC is born, and the driver chip and peripheral chips form a hardware platform, which is Hawkeye. With the support of the controller, Hawkeye represents the solution, and Accumulation will launch related solutions such as EMI solutions, highly integrated solutions and energy-saving solutions with Hawkeye. Accumulating the Hawkeye platform For direct customers, we offer integrated solutions that allow customers to focus on other designs such as cabinets and cooling to speed time-to-market; for end customers, they can quickly identify the use of the Hawkeye The core features of the display screen are no longer meant to "how to choose the good screen that suits you." I hope that I will always be online with my customers and think more about my customers. This is a enthusiasm for the display industry.
Why can Hawkeye be synonymous with a solution platform? Zhang Zhibin, Director of Accumulation Technology Display Products, gave a definition: "The solution platform refers to the selection of active components such as LED display driver IC/transistor switch/logic control for specific circuit design. The circuit design is implemented as a complete hardware platform (board layout/information transmission interface/power system), and then the system design is extended according to the requirements of the finished product; therefore, the meaning of selecting the Hawkeye solution platform is not only to select components but to select displays. The features and performance of the screen finished product. The function of the Hawkeye platform can be embodied in the following five parts:
1. Reduce LED reverse bias and reduce LED bad point probability l Hawkeye solution platform controls LED conduction state, maintain LED forward operation as much as possible, reduce LED reverse bias and reverse pressure breakdown, improve display lamp point Reliability!
2. LED dead point isolation function l will be limited by the SMT process virtual welding, external force impact lamp point drop, LED crossover caused by the cross and caterpillars, limited to a single pixel point, isolate a single dead point to the surrounding pixels The effect of the display is greatly improved, and the user experience after the display is installed is greatly increased, and the elasticity of the maintenance service is increased.
3. The display performance is still excellent under high refresh. The LED drive current is less than 10mA, which is more sensitive to the output brightness. When the refresh rate is higher than 2000 Hz, the fastest drive current response is nanosecond, while the eagle eye solution is at 40 nanoseconds. The output current response is still stable, allowing the picture to be displayed evenly.
4. High integrated circuit l uses MBI5353 48-channel driver IC, the number of driver ICs is reduced to 1/3, and the output pins are arranged in R/G/B in order, which is advantageous for high pixel density design, with QFN56 (8mm x 8mm) / TQFP64 (9mm x 9mm) package size has the advantage of significantly saving cloth area compared to SOP24.
5. Solve 7 big challenges l ghost shadow, white balance color shift, one line dark line, low gray uneven, gradual dark line, bad point isolation (open cross and short caterpillar), high contrast interference.
Whether the eagle eye platform can be fully presented, controller support is a key. Accumulates with the important controller manufacturers at home and abroad to jointly develop related functions. In the near future, the brightness adjustment template function will also be introduced. The control software supporting the Hawkeye solution platform can save the display effect of different percentages of brightness class. IC configuration, providing brightness adjustment for lossless grayscale. In his conclusion, Director Zhang emphasized: "Eagle Eye Platform hopes to help customers save product development time, quickly launch to gain market opportunities, and emphasize the significance of the Hawkeye platform as synonymous with finished product features and performance."
After all the speeches, Huang Bingkai, Director of the Accumulation Technology Marketing Department, led all the lecturers to the “Forecast Megatrend Summit Forumâ€, focusing on three major trends: zero emissions, urbanization with the Internet, and mutual stimulation through mutual questions. Kind of possibility. Regarding the issue of energy-saving screens brought by zero emissions, LMG George mentioned that the application of energy-saving screens does not have much significance for the rental market. Conversely, EMI and other solutions are relatively important, so the accumulation of Chen Qikai's general feedback is currently focused on EMI solutions. They all want to give customers better products. Urbanization may lead to the use of indoor small dot display screens, such as indoor advertising screens, monitoring rooms, etc., the chairman of the accumulation accentuates that there are still many problems in the design of small dot spacing, such as LED dead pixels leading to poor display performance. All need to solve the problem in the industrial chain, the middle and lower reaches; Yiguang Electronics Jin Haitao also echoes the common chip short circuit problem, not only the factors of the packaging factory, but also the closer cooperation between the upstream crystal electronics and other manufacturers to break through. . In the trend of the Internet, Yuan Shengchun, chairman of Nova Technology, mentioned the demand growth of clusters in the past two years, but Nova is more concerned with the three-way interaction of people, mobile phones, and displays. At present, they have some successful cases, and how to borrow them. This business model drives more growth and is a creative idea that requires more yuan. LMG George also added the Internet to make the display a lively interface, and the performers and the audience can enhance their interaction through the Internet. Through the discussion of the upper, middle and lower reaches of the industry chain, the series of big trends and all lecturers' lectures, the audience will be rewarded.
Li Yaping, general manager of Juxin Optoelectronics, reviewed the wonderful contents of all lecturers' speeches at the conclusion, and hoped that the platform with the accumulation seminar could bring more help to the LED display industry, and agreed with everyone in 2016.
Yang Lichang, chairman of Accumulation Technology, mentioned in the opening speech that the importance of the trend to the company lies in the fact that the trend is the first step to grasp the business opportunities. He suggested that after the rise of the commercial mode of online video downloading, the record industry could not make money by selling CDs, instead it was the singer's singing activities, which led to the development of the LED rental industry.
