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 develop a flexible multipoint microLED array for optogenetics applications

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.

KIMM developed a stretchable distortion-free microLED display

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'.

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.

TCL CSoT shows new flexible, wearable microLED display prototypes

TCL's CSoT showed its latest display prototypes at the company's DTC 2021 event. CSoT unveiled two new microLED display prototypes, that it never displayed before.

The first display is a small 1.37" 320x360 (353 PPI) wearable LTPS microLED display, that achieves a brightness of >2,000 nits. The display also uses TDDI touch technology (in which a single chip shares the display driver and the touch sensor).

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.
