BOE Jingxin Technology Delivers Its P0.9 COG Mini LED

BOE Jingxin Technology announced on its official WeChat page that its first major chip-on-glass (COG) P0.9 MLED product was delivered.

The self-developed P0.9 COG AM Mini LED is fabricated by mounting tailored chips to a glass substrate.

COG features more accurate process, deeper black levels, and ultra-high contrast along with excellent flatness and heat dissipation properties.

The COG-based Mini LED adopts an AM technology compatible to mass production and reproduces images through point-to-point direct drive. When displaying images with 1,000 nits of brightness, the Mini LED product can keep the instantaneous brightness at 1,000 nits.

Therefore, the product can genuinely present flicker-free still images and avoid the presence of 'water ripples'. Water ripples on screen is a common problem of PM LED products caused by excessively high instantaneous brightness, which may lead to headaches, dizziness and visual fatigue.

Additionally, the COG AM approach can facilitate perfect fitting of full-grayscale gamma curves, hence the smooth image transitions of the display particularly in a low-grayscale scenario.
