Our Micro LED Display achieved PPI the best in class based on LTPS display technologies, such as circuit design on a glass substrate, micro‐fabrication technology, and multi‐layer process. A full color display is realized with rich color reproduction by controlling each independent LED chip of RGB in accordance with chip characteristics.

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.
