Newly-Designed Pixel Circuit and Reflector Cavity with LTPS TFT for MicroLED Display

摘要

A 3.9” microLED display prototype with LTPS backplanes has been developed by using a newly-designed current and PWM hybrid driving technology to lower the color shift, resulting in achieving a higher frame rate. A novel approach for a reflector cavity process for improving outcoupling efficiency was also proposed.
