Abstract

A new mini-LED local dimming backlight with reflective dots is proposed for high uniformity, high contrast, and low power consumption in small LCDs. The proposed backlight, comprising a small number of mini-LEDs, was verified as having high luminance uniformity due to the optimized backlight thickness and light distribution of mini-LEDs.
