Embodiments provide a kind of screen luminance adjustment method, the screen that Fig. 3 is according to embodiments of the present invention is bright
The flow chart of degree control method, as shown in figure 3, the method comprises the following steps：
Step S302, the distance between measurement barrier and screen；
Step S304, the time not changed in the distance between this barrier and this screen is more than the situation of preset value
Under, screen intensity is automatically adjusted to the functional relationship between screen distance and screen intensity according to the barrier pre-setting.
By above-mentioned steps, measure the distance between barrier and screen；Do not send out in the distance between barrier and screen
In the case that the time of changing is more than preset value, according to the barrier pre-setting between screen distance and screen intensity
Functional relationship automatically adjusts screen intensity, solves in correlation technique in correlation technique and carries out in the screen intensity to mobile terminal
The problem of the regulation that cannot be become more meticulous with a distance from mobile terminal for user during regulation is it is achieved that be directed to user from movement
The regulation that the distance of terminal is become more meticulous, effectively solves the demand of each user, improves Consumer's Experience.
It should be noted that according to the barrier pre-setting to the functional relationship between screen distance and screen intensity certainly
The dynamic mode adjusting screen intensity can have many kinds, can set barrier, generally, barrier refers to user's
Face, certainly, user can also be exclusively by handss as barrier, after allowing the distance of handss and mobile terminal keep a period of time
Triggering automatically adjusts the brightness of screen, and for example, thing of placing obstacles is to the distance between mobile terminal display screen curtain D and display screen
Brightness C between functional relationship, such as D=kC+b, when adjusting screen intensity, can according to pre-set this is public
Formula adjusts screen intensity, and the value that k is can be configured based on experience value.
Fig. 4 is the schematic diagram of screen intensity setting according to embodiments of the present invention, as shown in figure 4, user can move
In terminal, screen intensity is set to automatically adjust, can also be set for automatic setting screen intensity one time period, that is, only have
Just realize screen intensity in the time period of setting to automatically adjust.In order to ensure the distance before distance of mobile terminal screen occurs
Change, and after stable distance after changing a period of time, just start to adjust the brightness of screen, thus avoid
