Kyocera and Osram are reportedly working on a new hybrid current and PWM microLED display driving technology. The new strategy can be used to avoid using lower pixel currents through microLED chips, thus reducing luminance deviation and colour shift even at lower grayscale levels.
The new driving technology was demonstrated with Kyocera’s 3.9-inch full colour µLED display based on an LTPS backplane. The technology also applied a reflector cavity process to increase the display brightness.
It is said the technology could be used for AR applications with its features of high brightness and advanced colour performance.
Kyocera have been involved in wearable applications based on Micro LED display technology; last year they presented a 1.8-inch µLED display for wearable devices.
