Method and system for adjusting screen brightness of mobile terminal and mobile terminal

Abstract

The invention provides a method and a system for adjusting the screen brightness of a mobile terminal and a mobile terminal. The method comprises the steps of detecting whether the mobile terminal stays at a manual brightness adjustment mode or not; if yes, comparing the current ambient light intensity and the limit light intensity corresponding to the current screen brightness, wherein each screen brightness in the manual brightness adjustment mode corresponds to a limit light intensity; and controlling the mobile terminal to switch from the manual brightness adjustment mode to an automatic brightness adjustment mode if the current ambient light intensity is greater than the limit light intensity corresponding to the current screen brightness. According to the method for adjusting the screen brightness of the mobile terminal, a circumstance that the well set screen brightness cannot meet user requirements when the ambient light intensity is changed to be very high under the manual brightness adjustment mode can be avoided, thereby avoiding dissatisfaction and complains of users caused by inability of seeing a screen clearly, and improving the user experience of the mobile terminal.

Description

technical field [0001] The present invention relates to the technical field of electronic equipment, in particular to a screen brightness adjustment method and system of a mobile terminal and a mobile terminal. Background technique [0002] At present, the screen brightness of mobile terminals such as smart phones usually has two modes: automatic adjustment and manual adjustment. The automatic adjustment is to automatically adjust the screen brightness to a more suitable visual brightness according to the ambient light intensity. Artificially adjust the screen brightness to a fixed brightness.
