Method for periodically and automatically controlling screen brightness of smart phone

Abstract

The invention discloses a method for periodically and automatically controlling a screen brightness of a smart phone, and is used for forcibly configuring a backlight control manner into an automatic adjustment manner in a certain time period. The method comprises the following steps of: configuring the backlight control manner into two manners including a manual adjustment manner and the automatic adjustment manner; configuring a time period in which the automatic adjustment manner is required to be used; monitoring system time of the smart phone; and configuring the backlight control manner according to the current system time. According to the method for periodically and automatically controlling the screen brightness of the smart phone, the backlight control manner is forcibly configured into the automatic adjustment manner in the time period when a night ambient brightness is lower, so that the eyes of a user can be avoided from being flashed by the over-backlight brightness at night, the function of eye protection is achieved, and the user experiment is improved as well; and besides, when the ambient brightness is higher, an automatic adjustment mode can be shut off and changed into the manual adjustment manner, the burden to the working endurance of the mobile phone due to the continuous working of a light sensing module is avoided, the load of a battery is lowered, the use time of the battery is prolonged, meanwhile, the light sensing module is effectively protected, and the service life of the light sensing module is prolonged.

Description

technical field [0001] The invention relates to a method for controlling the backlight of a smart phone, in particular to a method for automatically controlling the brightness of the screen of the smart phone at regular intervals. Background technique [0002] There are two main ways to control the screen brightness (i.e. backlight control) of smartphones: one is manual adjustment, usually through the display option in the Settings (Setting) or the power control bar (Power Control Bar); the other is Automatic adjustment, through the light sensor module (Light Sensor) on the mobile phone to detect the current ambient light intensity, and then control the backlight module to adjust the brightness of the backlight. [0003] Under normal circumstances, the backlight control mode of a smart phone defaults to a manual adjustment mode. When people use mobile phones at night, they often flash their eyes because the brightness of the screen is too bright, causing discomfort to the e...

Problems solved by technology

However, if the backlight automatic adjustment mode is turned on all the time, since the light sensor module is always working, this will cause a lot of burden on the battery life of the mobile phone, and will greatly affect the battery life; at the same time, it will continue to work without interruption It will also shorten the service life of the light sensor module
