We're happy to interview Yenrich, as part of our series of interviews with MicroLED Industry Association members. Yenrich, spun-off from Epistar and now part of the Ennostar group, develops mini-LED and micro-LED packaging. The company is focused on direct-view displays, both miniLED based and microLED based.

Hello! Can you introduce your company and technology?

Yenrich, a member of Ennostar, focuses on the development of Mini/Micro LED technology and products for fine pitch displays and provides customers with integrated solutions of front-end chips and back-end system applications.

Q: Can you say why you joined the microLED association and what it is you hope to achieve?
1.    Learn the latest Mini/Micro LED technology and information from the MIA and get more correct product roadmap in this field
2.    Understand the needs of Micro LED for AR/VR and automotive applications and technology

Taiwan-based MicroLED developer PlayNitride (a MicroLED Industry Association member) has demonstrated its latest microLED displays at Display Week 2023.

First up we have the company's tiled large-area microLED displays, called PixeLED Matrix. The company showed a 166" vertical installation, that is made from 324 modules. The total resolution is 1440x4860 (30 PPI, or a pixel pitch of 0.833 mm). This was a very nice looking demonstration.

China-based microLED display developer Sitan Technology demonstrated its latest microLED displays at Display Week 2023.

The company has developed four microLED microdisplays: 0.13" 1024x748 monochrome, 0.18"  800x600 monochrome, 0.18” 600x400 full-color and a 0.45" monochrome FHD panel. The company's 0.13" display offers a display density of 10,000 PPI (monochrome). The company also showed small transparent microLEDs.

During Display Week 2023, Seoul Semiconductor demonstrated new prototype display modules that use its WICOP microPixel technology. WICOP Pixel is a full-color one-chip vertically-stacked microLED technology that does not require wire bonding, packaging, or lens, and enables easier microLED display production.

Seoul Semi updates that its latest WICOP Pixels reach a brightness of 10,000 nits (up from 4,000 in its previous generation technology).

During Display Week 2023, Tianma demonstrated its latest microLED display prototypes - all of which are transparent displays, stating that the main application for such displays is in the automotive sector.

The first display is a 8.75" panel, offering a resolution of 880x480 (114 PPI), a brightness of 800 nits and high transparency of over 70%. The display is an active-matrix microLED produced on an LTPS backplane.

AUO has demonstrated its latest microLED displays at Display Week 2023. Most of these displays have been shown before, but this was an impressive lineup for the Taiwanese display maker, and we'll detail the displays below.

So first up we have the 13.5" 1920x1080 (163 PPI) transparent microLEDs, which AUO says is the highest-resolution transparent microLED display ever demonstrated. The display offers a transparency of 55% and a high brightness of 5,000 nits. The microLEDs used in this display are 30 micron in size.

Today we published a new edition of our Transparent MicroLED and OLED Market Report, with all the latest information and updates from this interesting upcoming industry and market.

Reading this report, you'll learn all about:

• Transparent OLED and MicroLED properties and advantages
• The transparent OLED and MicroLED industry
• What kind of transparent OLEDs are currently on the market
• The transparent OLED lighting market

The report package also provides:

• Transparent OLED display product listing
• A guide into buying transparent OLEDs
• The main challenges towards transparent displays
• Free updates for a year

This transparent displays market report provides a great introduction to transparent OLED and MicroLED technologies and covers everything you need to know about the market and industry now and in the future. This is a great guide for anyone who's thinking about adopting transparent displays in their products or that wants to understand this industry and market throughout.

AU Optronics released some very interesting information as the company gets ready to showcase its latest microLED displays and technologies at Touch Taiwan 2023.

So first of all, AUO announced that it has finalized the development of its wearable microLED display, and the company is now launching the 1.39" round smartwatch display commercially. AUO demonstrated the wearable microLED display back in 2021 - a 1.39-inch 472x472 full-circle panel, that was developed together with PlayNitride. It's not clear when AUO actually plans to start selling this display to its customers, and what will be its production capacity.

AUO, together with ITRI, developed a new 17.3" transparent microLED display, and deployed a few of these displays in a ferry operated by the Taiwan Kaohsiung Shipping Company. The Snoopy-featured Yawan Smart Ferry, will set sail for the first time on December 24, connecting Zhanerku, Cijin, and Gushan. The gesture-controlled AI smart window screen navigation system combines AR and eye tracking to show tourists information based on what they are looking at. 

The LTPS microLED displays offer a 1820x720 resolution and a 120Hz refresh rate. The transmittance is 55% and the peak brightness is 3,000 nits

We're happy to interview Lextar, as part of our new series of interviews with MicroLED Industry Association members. Lextar, a global LED developer, was established in 2008 in Taiwan as a subsidiary of AU Optronics, and is now part of Ennostar following a merger with Epistar. Lextar is producing microLED chips, and has launched its first commercial microLED products In 2018.

Q: Hello! Can you introduce your company and technology?
