LG Electronics has unveiled a new type of residential Magnit MicroLED TV, with a smaller pixel pitch than it showed before.

LG's new TV offers 4K resolution in 136", with a pixel pitch of 0.7 mm. LG's previous generation Magnit TVs offered a pixel pitch of 0.9 mm.

AU Optronics have been showing new microLED display prototypes, and the following video from Insight Media shows the company's booth and new displays at SID Displayweek 2022.

You can see AUO's stretchable 141 PPI display (a very interesting demo, developed together with PlayNitride), the rollable 14.6" 2K (202 PPI) LTPS microLED display, AUO's 1.4" circular 454x454 (326 PPI) microLED another stretchable microLED, this one 6.45" in size with a 900x450 resolution (163 PPI), and finally AUO's 17.3" 2000-nits 1280x720 transparent (60% transparency) microLED prototype.

Smart glasses developer Vuzix announced it has signed a series of agreement with Atomistic, that will give Vuzix an exclusive license of Atomistic's microLED microdisplay technology, that will have Atomistic design a custom backplane for Vuzix - and dependent upon achievement of various technical stages, the ability of Vuzix to acquire the company.

Atomistic has developed a novel approach to develop microLED microdisplays based on its material platform, which enables red, green and blue microLEDs based on the a single epitaxial structure. The team will develop microLED backplanes on 300 mm wafers.

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.

PlayNitride had an impressive Displayweek booth, with several exciting microLED displays on show - including transparent displays, tiled displays, automotive displays, PM-uLEDs and more.

Last week we posted a story detailing these displays, and now we found this good video by Insight Media that gives a great tour to the booth and the displays on show. Enjoy!

In 2021, Quantum Dots developer Nanosys acquired 3D Nanowire microLED display developer Glo. At Displayweek 2022, Nanosys showed Glo's latest new microLED microdisplay prototype. You can see a demonstration in the video below.

The display is 0.7-inch in size, with a resolution of 480x270, or 787 PPI. That is very low for a microdisplay. The microLED chip size is 7x7 um, and the brightness is 50,000 nits. The performance is underwhelming - however such a solution could find applications, depending on the price - and Nanosys suggests using it in an automotive HUD solution.
