The MicroLED-Info newsletter (August 10, 2022)

The MicroLED Industry Association (MIA) successfully concluded its kickoff meeting on August 2^nd. The work plan for the coming quarter was announced, and the association members were updated on work processes, collaboration activities and plans for the future.

The MIA is happy to announce that there are already over 15 members in the microLED association. In addition to its pre-launch founding members, the MIA welcomes the new members that joined since the official announcement on July 13. These companies include 3D Micromac, ASM Pacific Technology group, ClassOne Technology, Radiant Vision Systems and the Ennostar group (Epistar, Lextar, Yenrich and Unikorn).

China-based MicroLED microdisplay developer Jade Bird Display announced that it is developing a native full-color microLED microdisplay. JBD is working to integrate InGaN and AlInGaP on the same chip, fabricated using conventional thin-film processes.

JBD says it developed a proprietary (and patented) technology in which the epitaxy layers were designed to be less susceptibility to edge effects, which helps to increase the display's efficiency. JBD's technology also enables effective mesa sidewall passivation. JBD refers to its technology as monolithic hybrid integration and says it can reach a PPI of up to 10,000 with a pixel pitch of 2.5 um.

AvicenaTech, a developed of microLED-based chip-to-chip interconnects announced its Series A funding. The company raised $25 million from Samsung Catalyst Fund, Micron Ventures, and others.

The company's LightBundle I/O technology is based on arrays of GaN micro-emitters that leverage the microLED display ecosystem and can be integrated onto any high-performance CMOS IC. Avicena says it leverages recent advances in the display industry to enable high volume, low-cost production of highly optimized microLED arrays.

3D printer producer Anycubic announced a new consumer-grade pocket-sized 3D Printer, that is based on a small UVA microLED display, produced by JBD.

The display is JBD's standard 0.13" VGA display, but one that emits UVA emission. JBD also developed a custom projector for this new application. The extremely small, yet bright, display module, enabled Anycubic to design an extremely small printer (which is about the size of a 550 cl beverage can). The printer will be able to print details as small as 10 µm due to the high pixel density (>6000PPI) of the microLED display. The energy consumption during operation is only 6W.

According to a report from Korea, both Samsung Display and LG Display started to develop microLED microdisplay technologies.

Both companies have recently started to develop OLED microdisplays. According to the report, Samsung targets AR devices with its microLED microdisplay technology, while it targets VR devices with its OLED microdisplays. Samsung's microLED displays will achieve a resolution of 6,000 to 7,000 PPI (higher than its OLED devices).
