This document describes systems and directed at rejecting display leakage light in under-display sensors. In aspects, an ambient light sensor of an electronic device rejects leakage light originating from pixels in a display using a look-up table and an ambient light calculating formula.

The look-up table includes pre-calculated values of a leakage light ratio, for given operating conditions, that can be used to reject leakage light originating from displays by computing the ambient light calculating formula.

Disclosed is a method and an apparatus for backlight control and a display device. The apparatus comprises: a block brightness module for calculating an initial brightness value of each backlight block in a backlight source according to initial image data; a filtering module for performing spatial filtering and temporal filtering on the initial brightness value of each backlight block to obtain an adjusted brightness value of each backlight block; a control module for generating a brightness control signal according to the adjusted brightness value of each backlight block to adjust brightness of the backlight source. An intermediate brightness value of each backlight block is no less than the initial brightness value of that backlight block. Based on backlight adjustment for reducing power consumption, display effect reduction on a portion of image due to uneven brightness of the portion of the image during the spatial filtering is avoided.
