Abstract

The invention provides a backlight brightness adjustment method, a backlight brightness adjustment device, and a mobile terminal, wherein the method comprises the following steps of: detecting whetherthe backlight adjustment mode is a manual adjustment mode when receiving a light screen operation indication started to the mobile terminal in a state of off screen; if the backlight adjustment modeof the mobile terminal is the manual adjustment mode, acquiring a current first ambient brightness value and a second ambient brightness value stored when the screen is off; and if the absolute valueof the difference between the first ambient brightness value and the second ambient brightness value is greater than a preset threshold, adjusting the backlight brightness of the current screen to a first backlight brightness value corresponding to the first ambient brightness value. The application is capable of solving the problem that the screen is hard to see or the screen is dazzling due to the problem of backlight brightness when manually adjusting the backlight in the prior art.

Description

technical field [0001] The present application belongs to the technical field of mobile terminal control, and in particular relates to a backlight brightness adjustment method, a backlight brightness adjustment device, a mobile terminal and a computer-readable storage medium. Background technique [0002] At present, most mobile terminals (such as smart phones) on the market support automatic backlight brightness adjustment, so that the screen backlight brightness of the mobile terminal can be automatically adjusted according to the brightness of the current environment. However, due to differences in user habits, many users still choose to manually adjust the brightness of the backlight. [0003] In the prior art, if the backlight adjustment mode is manual adjustment, when the user turns on the screen, the backlight brightness defaults to the backlight brightness when the screen was turned off last time. According to this logic, the following technical problems will occur: ...
