The present disclosure provides a method for detecting light leakage of a screen, a method for detecting ambient light, and an apparatus for detecting ambient light. The method for detecting light leakage of a screen includes: acquiring display parameters of a screen, the display parameters including: a brightness value of the screen and grayscale values of respective pixel points within a preset display region of the screen; inputting the display parameters into a pre-trained neural network model, to process the display parameters using the neural network model, to obtain light leakage values corresponding to the respective pixel points; and obtaining a light leakage value of the screen based on the light leakage values corresponding to the respective pixel points. Based on the above technical solutions, the light leakage value of the screen can be accurately and reliably determined.
