Osram and Kyocera have worked together to develop a latest micro LED display driving solution for AR devices

Kyocera and Osram announced a new cooperation on a new Micro LED display driving technology. Kyocera has been focusing on the development wearable applications based on Micro LED display technology. In the year 2019, it lauchned a 1.8-inch Micro LED display for wearable device. 

It is reported that both companies have developed a hybrid current and PWM driving technology for Micro LED displays.

The new driving solution can avoid using lower pixel currents through Micro LED chips based on the descriptions by Kyocera and Osram.  In this way, the scheme can reduce lighting deviation and color shift even at lower grayscale levels.

The new driving technology was shown with Kyocera’s 3.9-inch full color Micro LED display based on an LTPS backplane. The technology also used a reflector cavity process to increase the brightness of display.

This latest technology could be used for Micro LED display for AR applications with its features of high brightness and advanced color performance.
