Samsung starts producing 89-inch LTPS microLED TVs

Towards the end of 2020, Samsung announced it's first "consumer" MicroLED TVs that adopt small microLED chips (this followed its professional/commercial TVs that used larger chips and are already in production for several years). These smaller TVs were scrapped later in 2021, and then Samsung further delayed its plans in April 2022 and did so again in June 2022, due to technical issues.

JBD is developing native full-color microLED microdisplays

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.
