A display device comprises: a display screen, a pixel layer, a backlight, and at least one ambient light sensor (ALS) which detects ambient light around the display device. An Optimal Power and Color Adjustment Module (OPCAM) (a) receives detected ambient light information, (b) identifies characteristics of the ambient light, including brightness and color temperature, (c) selects a pre-calculated combination of power level and color details that collectively enables pre-determined acceptable display quality of images displayed on the display screen within the particular viewing space, and (d) respectively forwards the pre-calculated power level and color details to concurrently trigger the backlight drive current controller and the pixel layer controller to provide a specific amount of drive current to the backlight and specific color characteristics, including an amount of color intensity of the pixel layer, which collectively yields the pre-determined display image quality, while optimizing power usage by the display device. |
