Xiaomi announces its first smart glasses with a 0.13-inch MicroLED microdisplay

Xiaomi announced its first smart glasses, called unimaginatively the Xiaomi Smart Glasses. These light-weight (51 grams) glasses will offer a monochrome (green) display and speakers, microphones and a 5MP camera, and will connect to your smartphone for notifications, navigation and will have applications such as real-time translation. It will support Xiaomi's XiaoAI Virtual Assistant.

Xiaomi says the microLED display is 0.13-inch in size, with a peak brightness of 2-million nits.The pixel pitch is 4 um. While not official, this is highly likely to be JBD's 0.13" VGA microLED display panel, revealed last year.

Vuereal demonstrates a transparent microLED display, to start pilot production soon

Canada-based microLED technology developer VueReal demonstrated a new transparent microLED display. The display is between 3 and 4 inches in size, with high brightness (over 3,000 nits) and very high transparency (85%).

The display in the video is produced on glass, but VueReal can also produce displays on flexible substrates. The company did not disclose the display's resolution (or whether this is a segmented display).

Royole shows a stretchable transparent microLED display prototype

China-based display maker Royole introduced a stretchable and transparent microLED display prototype at SID Displayweek 2021. The company says that this display, the first of its kind, is compatible with existing industrial manufacturing processes.

The prototype panel is a 2.7-inch 96x60 display (120 PPI) . It can stretch by up to 130% and bend up to 40 degrees. It is quite transparent, too - with a transmittance of 70%.

Vuzix launches its microLED display engines using JBD microdisplays

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.

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.

AU Optronics shows its microLED display prototypes at SID Displayweek 2021

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.

3D-Micromac launches a new microLED LIFT mass transfer tool

3D-Micromac announced a new microLED mass transfer tool, called microCETI. The company says its new technology can be used to transfer over 130 million microLEDs per hour.

MicroCETI is based on a laser-induced forward transfer (LIFT) process that can support almost any microLED material and shape. The tool also includes optional modules - a laser lift-off (LLO) module, and a single LED die repair module.
