According to a new report, China's LED producer Sanan Optoelectronics developed 10x20 micron LED devices (micro-LEDs) and is offering sample chips and testing data for microLED display makers. San'an aims to start producing these micro-LED chips on 6" wafers in Q4 2019.

Most microLED displays use chips produced on 4" wafers, and the move to 6" will enable lower production costs.
