Innolux unveils a 12.3" tiled microLED display module prototype

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.

AUO will show a rollable 14.6" microLED display, that offers a 2K resolution (202 PPI) with a 40 mm rolling radius. The company will also show a 17.3" 2000-nits 1280x720 transparent (60% transparency) microLED prototype. In 2021 the company demonstrated a smaller transparent display, which was even brighter at 3,000 nits.

Seoul Viosys unveils a new microLED microPixel technology called WICOP

LED developer Seoul Viosys announced a new technology called WICOP mp, that combines the company's no-wire, no-package WICOP tech with a PCB-based micro-IC, to create so-called micro Pixels.

Seoul Viosys Wicop microLED technology details

The company says that its WICOP technology makes it possible to populate brand-new semiconductor chips into a general manufacturing process directly without modification. Seoul Viosys says that using WICOP mc microPixels enables higher efficiency (as there's no efficiency degradation) and high density displays (up to 2000 PPI)

Tianma demonstrated new microLED technologies at SID Displayweek 2021

Tianma demonstrated several new microLED display prototypes at SID Displayweek 2021. First up is a 7.56" 720x480 (114 PPI) flexible MicroLED display, developed in collaboration with PlayNitride. The display is driven by an LTPS backplane and achieves a brightness of over 600 nits. The bending radius is 50 mm.

The second display is a tiled display that combines two 5.04" 480x320 (114 PPI) LTPS microLED displays. This one was develop again in collaboration with PlayNitride. The border (bezel) of the panel is less than 0.03 mm - although looking carefully at the display you can see a black line separating the two panels.
