摘要:
Systems, methods, and devices are provided for providing intra-frame luminance scaling to avoid drawing excessive power while still providing exceptional brightness. An instantaneous average pixel luminance of an electronic display may be determined. The instantaneous average pixel luminance may correspond to an amount of light currently being emitted by the electronic display due to a previous image frame and a current image frame. Based at least in part on the instantaneous average pixel luminance, the luminance of a subset of pixels of image data of the current image frame may be adjusted, thereby allowing the electronic display to operate at a relatively high brightness level without exceeding a power limit.
