To deal with the AMOLED panel supply crunch, Taiwan factory to develop Mini LED

Recently, according to foreign media reports, in view of the AMOLED intelligent mobile phone panel supply tight, and facing fierce competition, China manufacturers in LED backlight field, LED enterprises in Taiwan began to Chinese TV, intelligent mobile phone backlight applications and fine pitch screen with miniLED pixel. It is understood that the miniLED chip production size is about 100 microns, and does not require a huge amount of transfer, which is also the technical bottleneck faced by microLED.

In order to deal with the AMOLED panel tight supply situation, Android intelligent mobile phone manufacturers, especially China intelligent mobile phone manufacturers began using miniLED backlight to enhance the competitiveness of the equipment in the face of AMOLED. According to sources, compared to AMOLED, the MiniLED backlight design light local dimming can be achieved HDR (high dynamic range) and better color index, at the same time also has the same miniLED panel and the AMOLED panel thickness.

In addition, the LCD panel manufacturers AUO and Innolux (AUO) (Innolux) has also partnered with Android intelligent mobile phone manufacturers, the joint development of miniLED backlight solution. While RGB or white miniLED chip can be used for the backlight, the former can reach 100% of the NTSC color gamut, which can achieve 80-90% NTSC color gamut.

It is reported that a smart mobile phone panel backlight 5 inch 20-25 LED chip or about 9000 miniLED. EPISTAR has TV, intelligent mobile phone backlight applications and production of fine miniLEDs display pixel pitch ready. At the same time, rongchuang lextar electronics and energy technology respectively with AUO and Innolux cooperation, with the development of miniLED backlight tv.
