Kyocera and OSRAM have jointly designed a new hybrid current and PWM driving technology for microLED displays. The two companies says that this new driving scheme can be used to avoid using lower pixel currents through microLED chips, which reduces the deviation of the luminance and the color shift at lower grayscale levels.

Kyocera has presented a 3.9" full-color microLED display on an LTPS backplane that showed excellent performances that proves the validity of the new driving technology.

Kyocera also says that in this research they apply a reflector cavity process which increases the display brightness.

In June 2019 Micro-LED developer Glo announced a partnership with Japan-based display maker Kyocera to demonstrate a 1.8" Micro-LED display.
