Abstract: An information handling system may comprise a liquid crystal display having a plurality of pixels, an electrochromic material layer having a plurality of electrodes disposed between an interior surface of a chassis and a transistor-array layer, and a high reflection layer reflecting light emitted from an LED disposed between the electrochromic material layer and the transistor-array layer away from the interior surface of the chassis. A processor may execute code instructions of an electrochromic material regional backlight unit dimming control system to identify a low-intensity pixel region including a subset of the plurality of pixels associated within high dynamic ratio image data with a low intensity value, identify an electrode of the electrochromic material layer associated with the low-intensity pixel region; and pass a current through the electrode such that a portion of the electrochromic material becomes opaque to the light reflected from the high reflection layer.
