AI Technical Summary
Technical Problem
The under-screen optical sensor is interfered with the light reflected on the screen, resulting in inaccurate ambient light signal, affecting the display compensation effect.
Method used
By obtaining the current display content of the screen display area corresponding to the under-screen sensor, determining the display compensation value, and using the display compensation value and the actually received optical signal, the impact of reflected light on the ambient light signal is reduced, including device noise compensation and crosstalk noise compensation.
Benefits of technology
Improves the accuracy of the under-screen sensor to obtain ambient light signals and ensures the accuracy of display compensation effects.

Abstract
The present disclosure relates to a method for compensating light signals, comprising: obtaining the current display content of a screen display area corresponding to an under-screen sensor; determining a display compensation value based on the current display content; wherein the display compensation value indicates the impact of the screen display area displaying the current display content on the ambient light received by the under-screen sensor; and determining the ambient light signal received by the under-screen sensor based on the light signal actually received by the under-screen sensor and the display compensation value. In embodiments of the present disclosure, since the ambient light is determined based on the light signal actually received by the under-screen sensor and the display compensation value, the impact of reflected light from the screen display area on the ambient light signal can be reduced, making the ambient light signal received by the under-screen sensor more accurate.
