During the 2020 Chongqing Micro-LED Industry Innovation Forum, Konka introduced the world's first MicroLED Watch, the APHAEA Watch. This groundbreaking product uses a 2-inch microLED display with a pixel pitch of 0.12 mm - which means the resolution is around 400x400. The MicroLED chips are 30 um in size.
It is not clear how close Konka is to commercialize this product - but in any case this is a great achievement and this is the world's first microLED wearable display shown in a real product. The display is produced on an LTPS backplane, it achieves a brightness of 1,500 nits and a color gamut of 147% DCI-P3. Konka says that battery life of this watch is up to 35 days.
