Abstract
In example implementations, a display is provided. The display includes a plurality of light emitting diodes (LEDs), a thin film transistor (TFT) substrate, a liquid crystal layer, a color filter (CF) substrate, and a controller. The TFT substrate is formed over the LEDs to control emission of light from the plurality of LEDs. The liquid crystal layer is formed over the TFT substrate. The CF substrate is formed over the liquid crystal layer to control a color of the light emitted from the plurality of LEDs. The controller is communicatively coupled to the plurality of LEDs to group subsets of LEDs of the plurality of LEDs into a plurality of local dimming zones, wherein the subsets of LEDs in each one of the plurality of local dimming zones changes over time.
