Japan Display announced that it is developing micro-LED display technologies, and the company will unveil its first prototype at FINTECH Japan 2019 in early December. JDI will show a 1.6" 300x300 (256 PPI) display that is based on the company's own LTPS backplane with microLED chips developed by Glo.
The new display provides a wide viewing angle of 178 degress and offers very high brightness (3,000 nits).
In June 2019 Micro-LED developer Glo announced a partnership with Japan-based display maker Kyocera and demonstrated a 1.8" 3,000 nits Micro-LED display. This partnership seems to be similar - Kyocera provided the LTPS backplane while Glo provide the microLED chips.
