Title:
AMBIENT LIGHT SENSOR AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/082942
Kind Code:
A1
Abstract:
The present application provides an ambient light sensor and an electronic device. The detection precision of an ambient light sensor under a display screen can be improved. The ambient light sensor comprises: a light filtering unit array comprising a plurality of light filtering units that comprise red light filtering units, green light filtering units, and blue light filtering units; and a pixel unit array located below the light filtering unit array. The pixel unit array comprises a plurality of pixel units that are used for receiving a light signal generated after ambient light passes through a display screen and the plurality of light filtering units. The number of the blue light filtering units is greater than that of the red light filtering units, and the gravity center of a pattern formed by the red light filtering units, the gravity center of a pattern formed by the green light filtering units, and the gravity center of a pattern formed by the blue light filtering units in the plurality of light filtering units coincide.
