Abstract

Embodiments of the present disclosure provide a device for controlling luminance, a method of controlling luminance and a display device. The method of controlling luminance may comprise: obtaining a theoretical white balanced luminance value for each color of sub-pixel included in N pixels; obtaining a luminance controlling value for other colors of sub-pixels except for a ith color of sub-pixel included in each of the N pixels; and adjusting luminance of the other colors of sub-pixels except for the ith color of sub-pixel included in each pixel according to the luminance controlling value. The method of controlling luminance can be used in luminance controlling devices.
