Abstract

See full text

A terminal device with an ambient light detection function and an ambient light detection method are provided. The terminal device includes at least two photosensitive units arranged at a short distance, and the at least two photosensitive units are located in a slit area formed by a middle frame and a side wall of a display screen. Transparent black ink and opaque ink are respectively deployed in vertical projection areas of photosensitive areas of the at least two photosensitive units on cover glass, resulting in asymmetry in external ambient light energy sensed by the at least two photosensitive units. A processor performs differential calculation based on light energy sensed by the two photosensitive units by using a particular method, removes the impact of the light leakage generated by the display screen, and obtains brightness of peripheral real ambient light, to adjust brightness of the display screen.
