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.
