Wearables

Vuzix have officially launched its microLED display engines. These tiny (<0.4 cc and only 6.2 mm wide) devices offer over 2 million nits and feature 1 um pixels. Vuzix did not detail the resolution, but it less than HD (so likely to something like VGA or so).

Vuzix says that samples of the new engines are now available upon request. These are monochrome devices, and one would have to use three (red, green, and blue) for a full color display. Vuzix is developing full-color and higher-resolution (HD) engines. Vuzix says that its next-generation smart glasses will adopt these devices which are now on offer to customers.

AUO Optronics is showing its latest microLED ALED display prototypes at SID DisplayWeek 2021. Most of these aren't new display (AUO already demonstrated these last month) but it's the first time we got these on video:

You can see the 1.39" 472x472 (338 PPI) full-circle microLED display, developed together with PlayNitride. You can also see AUO's 12.1-inch 169PPI microLED display it first demonstrated in SID 2020, and the 9.4-inch 228 PIP flexible microLED prototype it also developed together with PlayNitride.

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.
