MicroLED developer VueReal says that it achieved a breakthrough in its MicroSolid Printing Platform, enabling it to go below 7um LED pitch (on the wafer) for full color microLED deposition. The company reports that its newest (and smallest) microLEDs show minimal impact on EQE, and this enables high-efficiency display production.

VueReal says that its new technology could soon compete on price with OLED displays while offering higher performance, and could be viable for many display segments - from wearables through smartphones to automotive and more. According to its current tests, its microLED displays will offer a brightness of 3,000 nits (and higher), while consuming around half the power compared to the latest AMOLED displays. In addition, its printing process is highly scalable and should not have a problem handling the demands of even the smartphone industry with hundreds of millions of displays per year.

LG Business Solutions launched its MAGNIT MicroLED TVs in India, and the company shared a nice launch-event video showing the first installation in India for the event:

LG's latest microLED TVs are the LSAD series, for which the main size is a 136-inch 4K display. The TVs offer 2000-nits and 120Hz, and are powered by LG's latest Alpha 9 AI-enhanced processor and the company's own webOS smart TV platform.

Texas-based A/V retailer GridHiFi posted an unboxing video in which they open and install a 110" Samsung MicroLED TV in their showroom:

As you can see, this TV comes pre-assembled (even though it is made from different tiles) and easily installed.

California-based integrator Just One Touch/Video & Audio Center announced that it has installed the first-ever residential installation of Samsung's latest 219-inch microLED The Wall TV. The price of this project was about $800,000. The installation took three days to complete.

The 219-inch display is made from the IW-008A modules, which offer a 0.84 mm pixel pitch, 120Hz refresh rate, a peak brightness of 2,000 nits and a maximum brightness of 250 nits.

Hong Kong based microLED microdisplay developer Raysolve Technology announced its first demonstration of a microLED microdisplay - a full-color 0.39" display.

The display is based on blue LEDs and a photolithographic QD color conversion layer. Raysolve is using a unique process, which is semiconductor process compatible, to create a novel optical design and material structure that achieves higher contrast, improved colors and a more efficient display.

India-based startup Focally unveils prototype AR glasses that feature several innovative technologies, including a full-color microLED based display engine.

Focally says that its Universe AR glasses will enable full-color and monochrome display modes, which leads us to believe that this display engine is built from 3 separate monochrome microLED displays, perhaps a similar design to Vuzix's display engine. Using waveguide optics, the company says that the display provides a 30-degree FOV. The company says that the display engine is the world's smallest and brightest, but does not provide any technical details.

In 2021, Austria-based C SEED released a high-end microLED TV, the $400,000 165" 4K C SEED M1, which has a unique foldable design, which makes use of seven large MicroLED panels.

C SEED now announced a new outdoor foldable MicroLED TV, called the HLR series. The displays (both based on seven panesl) offer a brightness of 4,000 nits and a resolution of 4K. There are two models, a 144" one which costs $298,000 and a 201" one that costs $590,000.

LED display market Leyard Optoelectronics announced that it developed the world's first mass-produced microLED display that uses quantum dots color conversion technology. Leyard collaborated with Saphlux (of which it owns around 12%).

Leyard adopted Saphlux's NPQD R1 micro LED technology, and have completed the development and testing of the display technology, and now it can mass produce NPQD-powered displays.

Researchers from Xerox PARC have developed a new micro-transfer printing technique that can be used to mass-transfer microLED devices. This technology offers high performance, simple and robust structure, and high process scalability and flexibility.

The new technology uses thermally induced adhesion modulation of shape memory polymer (SMP) materials. The idea is to use a print head that uses an individually-addressable micro-fabricated resistive heater array, which locally delivers heat for transfer of single microLED devices.
