Mini LED and OLED competition, Taiwan Shuanghu panel layout dynamic view

Mini LED will undoubtedly become the new product LED and panel industry actively cut. The reason is that the traditional backlight LED has been developed for many years, technology has reached a bottleneck, profits are relatively high, plus the OLED display a thin, flexible, high functionality, backlight display market constantly eroded, making no layout in the OLED display manufacturers, are actively involved in the function and costs are very competitive The development of competitive new products - Mini LED.

Mini LED after nearly 2 years of development, this year will be officially with the OLED in the display area of competition, from the characteristics of both compared with Mini LED direct type backlight with local dimming (Local Dimming) characteristics, comparable to high contrast effect of self luminous OLED, plus Mini LED direct type backlight it can produce high surface display Is to increase the selling point, will be able to compete with the OLED display, and in TV products as a benchmark, using Mini LED direct type backlight will cost less than OLED 20~30%, will help the manufacturers profit performance.

Because of the above reasons, the backlight module has sufficient resources in Taiwan factory two factory Innolux and AUO panel, solutions in recent years to the development of Mini LED backlight, display panel to create their own expectations of collocation differentiated products, to obtain the greatest profit.

From the technical point of view, Mini LED used in backlight dimming, can increase the number of partitions, in order to improve the LCD panel color and contrast, is expected to use a lot of LED. Calculation of a 5.5 inch LED panel of mobile phone usage, direct type backlight OD 2mm scheme, a single machine LED was about 2000~5000, if the thin scheme, the amount of LED is expected to pull twice as high. If the table display notebook computer to do the calculation, a 14 inch panel, in order to increase the contrast effect, the amount of LED is as high as 6000~7000.

However, with the increase of LED amount, manufacturers still need to overcome the problem of heat dissipation, resulting in addition, in order to more partition dimming, increased LED the number of pieces of content, the amount of IC will be increased, the display performance at the same time, the cost will be greatly increased, means that Mini can be used LED display product price take it Must fall in more than $1000, the high cost structure can afford Mini LED.

Therefore, when using Mini LED AUO strategy, lock in specifications, less price sensitive market application promotion, like gaming, and professional applications requiring high accuracy of color, is expected in the second half of 2018.

In contrast, Innolux in the use of Mini LED technology, the vehicle ahead. Innolux in 2018 CES released by the 10.1 inch AM MiniLED technology for vehicle backlight display technology, from the traditional side backlight into high contrast direct type backlight driving, in order to increase the clarity of display, improve the traffic safety.

On the technical point of view, AM MiniLED can do the current control precision, bright state images can be up to 1000 above nits level, which is compared with the OLED display screen is advantage; dark state zero brightness to completely shut down, so the contrast can be as high as 1000000: the level of 1, users can obtain more clear The message is still bright, especially with high visibility in the sun, in order to increase driving stability. In addition, Innolux to AM more flexible substrate MiniLED collocation (Flexible Substrate), as the best solution to special / surface needed for LCD backlight.

AM MiniLED in vehicle applications, which can achieve the same level of OLED contrast and sharpness in the picture with OLED and OLED will meet as equals, unable to meet reliability, service life and brand problems such as high temperature in automotive applications, with many competitive advantages. Optimistic about the car, Innolux electric cars and car networking three carts with the development trend of AM Mini, LED backlight will also further develop the soft substrate, shaped or curved LCD collocation, to meet the needs of customers in the vehicle design and appearance requirements, to provide more in line with the future direction of the product design of the concept car forward.
