Embodiment Construction

[0038] The present invention provides a method and system for automatically adjusting backlight brightness. In order to make the purpose, technical solution and effect of the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0039] Such as figure 1 As shown, a method for automatically adjusting backlight brightness, the steps include:

[0040] S100. The mobile terminal acquires the current ambient light intensity value once every timeout period, and adjusts the backlight brightness of the mobile terminal according to the ambient intensity value;

[0041] That is, the mobile terminal periodically detects the ambient light intensity of the surrounding environment of the mobile terminal through the light sensor accord...

Abstract

The invention discloses an automatic backlight brightness adjustment method and system. The automatic backlight brightness adjustment method comprises the following steps: a mobile terminal acquires a current environment light intensity value of every other timeout and adjusts the backlight brightness of the mobile terminal according to the current environment light intensity value; the absolute value of the difference value between the current environment light intensity value and the environment light intensity value obtained before the timeout is computed, and if the absolute value is greater than a preset threshold value, the timeout for acquiring the current environment light intensity value next time is set according to a corresponding function relationship between the absolute value and the timeout. According to the invention, the problem that the backlight brightness is adjusted repeatedly because the light intensity of the surrounding environment of the mobile terminal continuously changes is solved, so that the electrical energy saving effect is truly realized, and great convenience is brought to a user.

Description

technical field [0001] The invention relates to the field of communication applications, in particular to a method and system for automatically adjusting the brightness of a backlight. Background technique [0002] At present, mobile terminals have widely used light sensors to detect the ambient light intensity around the mobile terminal, so as to automatically adjust the backlight brightness of the mobile terminal according to the ambient light intensity, so as to achieve the purpose of saving power and making the screen display content clearly visible. [0003] However, this method has drawbacks: when the light intensity in the environment changes at a relatively fast frequency (such as sitting by the window of a speeding train, etc.), the backlight brightness of the mobile terminal will be adjusted repeatedly, making the user feel that the screen brightness is always changing. Changes, not only did not save power but also caused inconvenience to users. [0004] Therefore...
