Mini LED competes with OLED this year, the dynamic overview of the Taiwan panel double tiger layout

Mini LED has undoubtedly become a new product that is actively cut in by the LED and the panel industry. The reason is that the traditional backlight LED has been developed for many years. It has reached bottlenecks in technology, and the profit is relatively low, and the lightweight, flexural and flexible display of the OLED display, which constantly eroded the backlight display market, made the manufacturers who were not laid out on the OLED display were actively engaged in the competitive power and cost. The new product of contention - the development of Mini LED.

After nearly 2 years of development, Mini LED will formally compete with OLED in the field of display this year. Compared with the characteristics of the two, the straight down backlight with Mini LED has the characteristics of regional dimming (Local Dimming), which can compare the high contrast effect of OLED self luminescence and the display of high surface with the Mini LED straight backlight. To increase its selling point, the device will be able to compete with the OLED display, and on the basis of the TV products, the cost of using the Mini LED straight down backlight will be lower than OLED 20~30%, which will help the manufacturer's profit performance.

Because of the above reasons, there are two major panel factories in Taiwan area with adequate backlight module plant resources and group creation. In recent years, the Mini LED backlighting solution has been fully developed.

The Mini LED backlight mainly focuses on the competitive display market

From the technical point of view, the Mini LED application on the backlight can increase the number of dimming partitions to improve the color and contrast of the LCD panel, and it is expected that a large number of LED will be used. Calculation of a 5.5 inch mobile phone panel LED use, straight down backlight OD > 2mm scheme, a single machine LED consumption of about 2000~5000, if the use of thin scheme, LED dosage estimate will be doubled. In order to increase the effect of high contrast, the LED use of a 14 inch notebook panel is more than 6000~7000.

However, with the increasing use of LED, manufacturers still need to overcome the attendant heat dissipation. In addition, in order to make more partition dimming, increasing the amount of LED numbers, the amount of IC will rise synchronously. As the performance improves, the cost also increases significantly, which means that the price of the display product with Mini LED can be used. It has to fall above $1000 to afford the high cost structure of Mini LED.

Therefore, on the strategy of using Mini LED, the friend is locked in the promotion of the application market with high specification and less sensitive to price, such as competition and professional application with high color accuracy, which is now expected to be shipped in the second half of 2018.

Group creation group push Mini LED backlight rush car display market

In contrast, group creation in the use of Mini LED technology, car use first. Group creation Optoelectronics in 2018 CES exhibition launched the use of 10.1 "AM MiniLED technology back light display technology, from the traditional side into the backlight into a high contrast straight backlight, to increase the clarity of traffic display, improve the safety of driving.

On the technical point of view, AM MiniLED can achieve accurate current control, the bright picture can be pulled up to 1000 nits levels, which is the advantage of the OLED display; the dark state is close to the completely closed zero brightness, so the contrast can be as high as 1000000: 1, the user can get clearer and clearer. The bright message, especially in the sun, is still highly visible to increase the stability of the vehicle. In addition, group creation is more AM MiniLED with soft substrate (Flexible Substrate), which is the best solution for the backlight required for the heterogeneous / surface LCD.

In vehicle application, AM MiniLED can not only achieve the contrast of the same grade of OLED, but also compete with OLED in the picture sharpness, and no OLED can not meet the reliability, life and branding of high temperature and so on in the vehicle application, and has many competitive advantages. The development trend of three big cars with self driving, electric vehicle and car networking will be developed, and the AM Mini LED backlight of soft substrate will be further developed to match the special-shaped or curved surface LCD to meet the design and appearance requirements of the car customers, and move towards the product which is more consistent with the design of the future concept car.
