Abstract
The embodiment of the invention discloses a method for adjusting brightness of a display screen and terminal equipment. The method comprises the steps that the terminal equipment monitors the light intensity of a current environment; the terminal equipment adjusts the brightness of the display screen of the terminal equipment according to the light intensity, and the brightness is in positive correlation with the light intensity. The brightness of the display screen can be changed along with the environment brightness, the change is achieved in a positive correlation mode of the brightness and the light intensity, and the change can be applied to the situation that when the light intensity of the environment is brightened, the display screen becomes brighter so that a user can clearly see the content displayed on the display screen under strong light, and the change can also be applied to the situation that when the light intensity of the environment is darkened, the display screen becomes darker, so that on the one hand, the display screen is soft in brightness and harmless to eyes; on the other hand, more electricity can be saved. Therefore, the brightness of the display screen can be controlled flexibly to make the brightness suitable for the application environment and the application requirement of the user.
