Problems solved by technology

[0006] The purpose of the present invention is to provide a screen backlight control method, system and mobile terminal, aiming at solving the problem of using a fixed time length as the basis for judging that the backlight is turned off in the prior art, without taking into account the different application programs. The operation time and interface stay time are different, so the judgment method of fixed duration is difficult to meet different needs, which will cause inconvenience to users

Embodiment Construction

[0020] In order to make the purpose, technical solutions and beneficial effects of the present invention more clear, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] In the embodiment of the present invention, the distance between the user's face and the mobile terminal screen is detected by adding a distance sensor. When the distance is within the preset distance interval, the user is considered to be in the state of browsing the screen, and the screen backlight is kept at this time; Outside the preset distance range, the user is considered to be in a non-browsing screen state, and the screen backlight is turned off at this time to save power. The embodiment of the present invention solves the problem of using a fixed duration as the basis ...

Abstract

The invention provides a method, a system and a mobile terminal for controlling screen backlight, and is applicable for the technical field of controlling screen backlight. The method comprises the following steps of: measuring the distance between a user face and a screen of the mobile terminal; judging whether the measured distance between the user face and the screen of the mobile terminal is in a preset distance region; when the distance is in the preset distance region, keeping the screen backlight open; and when the distance is out of the preset distance region, shutting off the screen backlight. By the invention, the screen backlight can be controlled intelligently so as to meet user requirements maximally; a browse effect can be ensured; and a user experience can be improved.

Description

technical field [0001] The invention belongs to the technical field of backlight control, and in particular relates to a screen backlight control method, system and mobile terminal. Background technique [0002] In the prior art, the screen backlight of the mobile terminal is set for a fixed time, and when the non-operation time reaches a preset time, the screen backlight is turned off. [0003] The defective of above-mentioned existing scheme is as follows: [0004] The backlight control of the existing schemes all use a fixed duration as the judgment basis, which does not take into account that when using different applications, the user's operation time and interface stay time are different, and the fixed duration judgment method is difficult to meet different needs. cause inconvenience to users. [0005] For example, the backlight off time set by a general mobile terminal is: 15-30 seconds when there is no operation. However, in some browsing applications, such as e-b...
