TCL announced smart glasses with a color microLED display

TCL announced a new AR smartglasses product, which it calls the Thunderbird Smart Glasses Pioneer Edition. TCL did not reveal much, but it says the color display is based on microLED technology, with a pixel pitch of 4 um. TCL did not release any estimated shipping dates or a price for this new product, which is likely still at an early stage.

The video above is not clear, but it seems as if this solution uses three monochrome microdisplays, combined to show a single full-color image (the video shows one panel, but it later shows three monochrome images combined into one full-color display). This kind of solution was suggested by Vuzix, based on JBD's 0.13" VGA monochrome microdisplays. Which incidentally offer a pixel pitch of 4um, which leads us to speculate that TCL is also basing its Thunderbird glasses on JBD's displays.

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.

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.

AUO developed a 1.39-inch 338 PPI full-circle MicroLED display

AUO Optronics will demonstrate several new MicroLED display prototypes at Touch Taiwan 2021. AUO now brands its microLED displays as ALED displays.

The first display, which you see above,is a 1.39-inch 472x472 (338 PPI) full-circle microLED display. AUO says that this is the highest-density MicroLED display ever developed. AUO did not disclose more about this display (which was developed together with PlayNitride) but the company says that it offers ultra-wide viewing angles and high brightness.

Konka announces the APHAEA MicroLED Watch

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.

Epistar's chairman - MicroLEDs to be adopted first by smartwatches, but it will take 3-4 years

Digitimes reports that Epistar's chairman, Lee Biing-jye says that he estimates that the first volume application for microLED displays is going to be in the smartwatch industry - but that will still take 3-4 years to actually materialize. Volume adoption in the TV market will take at least 4-5 years.

Epistar is developing microLED epitaxy and chip technology (in collaboration with AUO) and still has challenges to overcome, mainly in the mass transfer area. The company expects to achieve reliable production capabilities within 2-3 years. Epistar needs also to improve the yield rates for microLED epitaxy and reduce costs for mass transfer processes.

RiT Display shows a microLED wearable display prototype

In December 2019 Taiwan-based PMOLED display maker RiTDisplay announced that it plans to launch its first MicroLED displays in 2020. Last week during SID Displayweek 2020 the company demonstrated its first prototype, as can be seen in the video below.

The company did not reveal any technical specifications or discuss any commercialization plans.
