Abstract

The invention discloses a backlight brightness adjustment method for a display screen and a mobile terminal. The method comprises the following steps: obtaining shaking frequency of the mobile terminal, matching a preset frequency section to which the shaking frequency belongs, wherein each preset frequency section corresponds to a backlight brightness adjustment strategy, and adjusting the backlight brightness of the display screen in the mobile terminal according to the backlight brightness adjustment strategy corresponding to the preset frequency section to which the shaking frequency belongs. By adopting the backlight brightness adjustment method disclosed by the invention, the flicker problem of the backlight brightness of the display screen in the mobile terminal is avoided, the service life of the display screen is prolonged, the visual acuity of a user is protected and the user experience is greatly improved.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a method for adjusting the brightness of a backlight of a display screen and a mobile terminal. Background technique [0002] Existing mobile terminals can automatically adjust the brightness of the backlight of the display screen by acquiring the ambient light brightness value. The mobile terminal can perceive the ambient light brightness value through the light sensor, and automatically adjust the backlight brightness of the display screen according to the ambient light brightness value. When the ambient light brightness value decreases, the backlight brightness of the display screen is adjusted to a lower backlight brightness. If When the ambient light brightness value increases, the backlight brightness of the display screen is adjusted to a higher backlight brightness, thereby achieving the purpose of reducing product energy consumption and protecting users' eyesigh...
