Abstract: Embodiments of the present application provide a method and apparatus for locating a sensor under a display screen and an electronic device, which can effectively improve performance of the sensor, thereby improving performance of the electronic device. The method includes: acquiring an assembly tolerance region in the display screen, where the assembly tolerance region corresponds to an assembly tolerance of the sensor; lighting up pixels at different positions within the assembly tolerance region sequentially; acquiring multiple pieces of sensing data of the sensor when the pixels at different positions are lit up sequentially, the multiple pieces of sensing data being data obtained after the sensor sequentially receives light signals emitted by the pixels at different positions; and determining a position of the sensor according to the multiple pieces of sensing data.

Abstract: A method for measuring an intensity of ambient light at an electronic device, and a electronic device and a chip are provided. The electronic device includes a screen, and the screen is configured to be deemed at a dimming frequency. The method includes the following. Mixed light including the ambient light and screen leakage light is collected. A DC mean value of the mixed light is obtained. A DC mean value of the screen leakage light is obtained. A DC mean value of the ambient light is determined by subtracting the DC mean value of the screen leakage light from the DC mean value of the mixed light. The DC mean value of the ambient light is indicative of the intensity of the ambient light.
