According to reports early in 2020, Samsung Electronics partnered with Epistar and PlayNitride that will enable Samsung to release its first true microLED TVs by the end of 2020. A new report from Korea suggests that Samsung is struggling with technology issues and it is not likely it will meet its goal of a product release in 2020.
The reports suggest that production yields are very low - apparently Epistar is not able to provide Samsung with the millions of microLEDs required to produce its TVs. Another major issues is Samsung's transfer process which is still not accurate enough - with the result being that display assembly yields are painfully low.
Samsung is already producing microLED TVs - but these emissive displays actually use mini-LEDs (or quasi microLEDs) chips. Moving to smaller microLED chips will enable Samsung to produce smaller displays of higher resolutions. Samsung's current LED supplier for its "microLED TVs" is Sanan Optoelectronics - which is also developing microLED technology and aims to become Samsung's second supplier for such chips.
