Taiwan-based display maker Innolux demonstrated a 12.3" microLED tiled seamless display module prototype, based on an LTPS backplane. The display achieves a brightness of 700 nits and a resolution of 480x180 (40 PPI)
The display is driven by an active matrix backplane, and uses inkjet-printed quantum dots based color conversion system (which we do not have any more info for, as of now). The LEDs themselves are 20x40 um in size.
We believe this is Innolux's first public microLED prototype (the company was focused on direct-view miniLED displays until now).
