AUO and Innolux split Mini LED backlight display market
[Abstract] Mini LED is undoubtedly becoming an emerging product that LED and panel industry actively enter. The reason is that the traditional backlight LED has been developed for many years, has reached a bottleneck in technology, the profit is relatively low, coupled with the high functionality of OLED display thin, flexible, and constantly eroding the backlight display market, making Manufacturers not on the OLED display are actively investing in both functional and cost competitiveness.
The latest news, Mini LED is undoubtedly an LED and panel industry active cutting-edge products. The reason is that the traditional backlight LED has been developed for many years, has reached a bottleneck in technology, the profit is relatively low, coupled with the high functionality of OLED display thin, flexible, and constantly eroding the backlight display market, making Manufacturers that are not on the OLED display are actively investing in the development of Mini LED, a new product that is highly competitive in terms of functionality and cost.
After nearly two years of development, the Mini LED will formally compete with OLEDs in the display field this year. Compared with the characteristics of the two, the direct-type backlight with Mini LED has the characteristic of local dimming, which is comparable to OLED. The high contrast of luminescence, coupled with the Mini LED direct type backlight, makes it possible to create a high-surface display to increase its selling point, and it can compete with OLED displays, and the cost of adopting a Mini LED direct-type backlight is based on TV products, will be lower than OLED 20 to 30%, and help manufacturers profit performance.
For these reasons, AUO and Innolux, the two major panel manufacturers in the Taiwan region with sufficient backlight module plant resources, have been developing Mini LED backlight solutions in recent years and expect to create differentiated display products with their own panels, to get maximum profit.
AUO Group Mini LED Backlight Main E-sports display Market
From a technical point of view, the Mini LED is applied to the backlight and can increase the number of dimming partitions to enhance the color and contrast of the LCD panel. It is expected that a large number of LEDs will be used. Calculate the LED usage of a 5.5-inch mobile phone panel and the direct-type backlight OD ≧ 2mm solution. The single-unit LED consumption is about 2000-5000. If the thin-type solution is adopted, the estimated LED usage will be doubled. If the desktop display is used as a calculation, a 14-inch notebook computer panel is used, in order to increase the high contrast effect, the LED usage is as high as 6000-7000.
However, with the increase in the use of LEDs, manufacturers still need to overcome the ensuing heat dissipation problems. In addition, in order to increase the number of LED chips, the usage of ICs will increase in tandem with the increase in LED display performance. At the same time, the cost has also increased significantly. This means that the price band of display products that can use the Mini LED must fall above US$1,000 to afford the high-cost structure of the Mini LED.
Therefore, AUO’s strategy of adopting Mini LED is locked in the promotion of application markets with high specification requirements and low price sensitivity, such as e-sports and professional application products that require high color accuracy, and are currently expected to In the second half of 2018, shipments will be made.
Innolux Group pushes Mini LED backlight to attack vehicle display market
In contrast, Innolux adopts the Mini LED technology to use the vehicle first. Innolux announced a 10.1-inch AM MiniLED technology for automotive backlight display technology at CES 2018. It converts traditional side-entry backlights into high-contrast, direct-lit backlights to increase the clarity of driving displays and improve driving safety.
From a technical point of view, the AM MiniLED can achieve precise current regulation. The bright state of the picture can be increased to more than 1000 nits. This is an advantage over the OLED display; the dark state is closer to the fully closed zero. Brightness, so the contrast can be as high as 1,000,000. 1 level, the user can get a clearer, brighter message, especially in the sun still have high visibility to increase driving stability. In addition, Innolux uses the AM MiniLED with Flexible Substrate as the best solution for backlights for profiled/curved LCDs.
AM MiniLED can achieve the same contrast ratio of OLED in automotive applications, and it can resist sharpness in the sharpness of the screen with OLED, and it will not be able to meet the reliability, longevity and branding of OLED in automotive applications. The product has many competitive advantages. Innolux is optimistic about the development trend of self-driving cars, electric vehicles and car networking, and will further develop AM Mini LED backlights for flexible substrates, with special-shaped or curved LCDs to meet the needs of automotive customers in terms of design and appearance. To provide products that are more in line with the future concept of car design.
