In some embodiments, when the distance is not more than safety value, control the display content of screen with it is described away from
From reduction and thicken.User is in order to see the display content of screen clearly, it has to increase the distance between screen.
In some embodiments, screen brightness regulation method further includes：
The distance between statistical screens and face are more than the time of safety value；
When the time being more than preset value, screen is made to extinguish.
The time that the distance between screen and face are more than safety value is more than setting value, and explanation can not be bright by increasing screen
It spends to stimulate user, screen is made it away from, for example, certain users can receive very high screen intensity；If user
Holding keeps the distance to watch screen for a long time, then can be by more serious damage.In this regard, it is provided with relevant safeguard measure,
Extinguish screen, user is forced to adjust the distance away from screen.
Compared to the prior art, screen brightness regulation method provided by the present application, can be between screen and face away from
When from more than safety value, control screen brightness variation, make screen intensity with it is described apart from positive correlation, to ensure viewing effect；
When the distance between screen and face are less than safety value, control screen brightness variation keeps screen intensity and the distance negatively correlated,
