Tianma shows several MicroLEDs prototypes at Displayweek 2024, including automotive displays, transparent displays, and wearable ones.

The first display was an automotive, a transparent 8.07-inch octagon-shaped display aimed towards digital side mirror applications (to be placed inside the vehicle). The display offers a transparency of 55%, a resolution of 608x1204 (167 PPI) and a brightness of 1,500 nits.

Innolux showed several new microLED display prototypes at Displayweek 2024, as it focuses on microLEDs as its next-generation display solution.

First, the company showcased a large 106" tiled microLED TV display, build from 96 12.3" modules. The display uses 20x40 um blue microLED chips (with QD color conversion) and an LTPS backplane.

Visionox showed a large 88-inch tiled microLED display, with a pixel pitch of 0.5 mm, based on 25 micron LEDs and an LTPS backplane. The display feature low (<5%) reflectance and a brightness of up to 1,200 nits.

Vistar also showed a 14.5" panel, a single module that is used to build the 88-inch TV. Visionox says that it developed a dedicated microLED driver IC, that enables 10-bit color depth and "True Color" presentation. Vistar says that it reaches production yields of 99.995% in its mass transfer process, and a repair process that enables perfect displays.

MicroLED-Info offers custom-tailored seminars for companies interested in deepening their team's understanding of various MicroLED-related topics, training new personnel, assessing the relevance of a certain field for their company or simply honing their employees' MicroLED skills.

These seminars are built specifically according to the customer's needs and requests and take place online. Employees from around the world can join the meeting to learn, ask questions and discuss issues which are relevant to their interests. Such seminars have already had great success among past customers. Here's what a recent company, a world-leading materials and components manufacturer, had to say about the service:

"We recently had the pleasure of engaging with MicroLED-info for a professional training session on MicroLED technology. Their private seminar was not only detailed and knowledgeable but also incredibly insightful, providing us with a comprehensive overview of the technology and its marketplace. The depth of information extended to the supply chain, enabling our team to swiftly grasp the critical aspects necessary for strategic decision-making.

At Displayweek 2024, TCL CSoT demonstrated its impressive 163-inch 4K (0.9375 mm pitch) tiled MicroLED display on show, that offered very high brightness (10,000 nits).

TCL says that the display has a 'nanosecond' response time, and its lifetime rating is over 100,000 hours. This is TCL's X11H Max commercial MicroLED TV, priced at $110,000.

AUO had an impressive booth at Displayweek, showing some of its latest microLED prototypes. It is clear that the company is highly focused on microLED technology as its next-gen display strategy.

First up, with a 31" large area single-panel microLED, which AUO says is the world's largest. The display is produced on a single glass LTPS backplane, and offers 120Hz and a brightness of 500 nits. AUO calls this a Large Size A.R.T. MicroLED display.

Researchers from HP propose a new composable monitor design - that is based on microLED display modules (tiles) that can connect together to construct complete monitors. The researchers explain that microLED is a key technology as it enables a bezel-less design.

The main idea is to create Lego-like building blocks, both flat and curved, that can connect in both horizontal and vertical configurations. 

Vuzix announced that it has signed a multi-phase development contract with Garmin for next generation nano-imprinted waveguide-based display system. These systems will also use microLED microdisplay engines.

Vuzix will develop and deliver in succession, waveguide based optical systems with full custom microLED projection engines, and then ultimately production units.
