Abstract

We report on the design and performance of a direct‐lit LCD backlight prototype which is only 5 mm thick and capable of full array 2D local dimming. Equipped with a 15.6” LC display panel, the prototype reaches peak brightness of 2000 nits. The measured contrast numbers meet VESA DisplayHDR 600 specification.
