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!
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.
PlayNitride demonstrates its latest microLED display prototypes and technologies at SID Displayweek 2022.
At the entrance to PlayNitride's booth, you can see a long 132-inch tiled microLED display, made from 192 modules (each 5" in size). The 7680x1080 59PPI display is completely seamless and offers 3,000 nits and a 116% NTSC color gamut.
AU Optronics announced that it will showcase new MicroLED display prototypes next week at Touch Taiwan 2022.
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.
Researchers from Japan's Toyohashi University of Technology and the Okinawa Institute of Science and Technology Graduate University have developed a flexible, multipoint microLED array film that can be flexibly attached to cover the brain and can illuminate specific brain regions.
The manipulation of neural activity by light (enabled by optogenetics), requires a thin, flexible and lightweight lighting source that is not toxic to living tissue. The new microLED film is highly suitable for this task, and the researchers hope that such devices will create a new area of neuroscience research aimed at comprehensively understanding the brain information that underpins how neural activity, behaviors, and disorders are linked.
Researchers from the Korea Institute of Machinery and Materials (KIMM) have developed a stretchable microLED display, that can be stretched in both directions. The researchers say that the display can stretched by up to 25% without distortion to the image.
The researchers report that they have managed to successfully fabricate a 3" microLED display. This was achieved by using metamaterials with unique mechanical properties that do not exist in nature - mainly that if they are stretched in one direction, they also stretch in the perpendicular dimension, and so the display is not distorted. They term the display a 'metadisplay'.
Taiwan-based panel semiconductor provider PanelSemi Corporation launched the world's first flexible active-matrix Mini-LED display at CES.
The display, called Primary, is a 55-inch HD resolution (1.2 mm pitch) miniLED direct-emission that is highly flexible, light (1 Kg for the whole display) and thin (1 mm thickness). It can be flexed to a concave, convex, s-curve, cylinder, and rollable shapes and four displays can easily be joined to create a 110-inch display. PanelSemi says that Primary is highly efficiency, and 4 hours of use can be driven by a single 10 K-mAh power bank.
Tianma Microelectronics held its first "2021 Micro-LED Ecosystem Alliance Conference" in Xiamen, China, during which several producers and researchers gathered to discuss microLED technologies and challenges.
During the conferences, Tianma showed several new microLED prototype display, including some new ones. The first display is a 9.38" 960x480 (222 um pixel pitch) transparent LTPS panel. Tianma's second-gen transparent panel features higher transparency (>70%), larger size and a refined TFT process compared to the company's first-gen transparent microLEDs shown in 2019.
