Abstract

Abstract : We report our progress on a monitor‐sized, dimensionally and thermally stable mini‐LED backlight enabled by a patterned glass diffuser (PGD). Our backlight uses 5, 000+ fewer mini‐LEDs per monitor — 4/9 times that in a reference mini‐LED backlight relying on a thicker diffuser plate, while it is thinner and achieves similar uniformity and luminance compared to the reference mini‐LED backlight.
