Method and device of adjusting of screen luminance of terminal and terminal

Abstract

The invention discloses a method and a device of adjusting of screen luminance of a terminal and a terminal. The method comprises that the current spatial position state of the terminal is acquired, and the spatial position state comprises the initial coordinate value of the terminal. When the spatial position of the terminal changes, the coordinate offset value of the terminal relative to the initial coordinate value after changing is acquired. When the coordinate offset value meets an adjusting condition, the screen luminance of the terminal is adjusted. By using the method and the device of adjusting of the screen luminance of the terminal and the terminal, not only electricity is further saved in a using process of the terminal, but also the phenomenon that the user hangs up by mistake caused by mis-turning on a background light of the screen can be prevent from occurring.

Description

technical field [0001] The present invention relates to the technical field of touch screens, in particular to a terminal screen brightness adjustment method, device and terminal. Background technique [0002] At present, with the widespread application of touch screen technology, there are more and more touch screen devices using touch screens, among which, touch screen mobile phones are most widely used. But along with the screen size of the touch-screen mobile phone is getting bigger and bigger, the user just can't avoid the problem that consumes more power when using the touch-screen mobile phone. For example, sometimes the user puts the mobile phone on the table or in the bag directly after using the mobile phone, and does not actively turn off the screen brightness. In this case, the mobile phone will turn off the screen brightness after a certain delay time. Time is also a power-consuming process. And because the screen brightness is not turned off, some unintention...

AI Technical Summary

Problems solved by technology

Among them, the distance parameter of the distance sensor in the touch screen mobile phone is set at the factory, and the detected distance is a fixed value and cannot be modified.

[0004] However, when the user uses a touch-screen mobile phone to make a call, it is more casual to place the mobile phone next to the ear. Inadvertently, the mobile phone will be a little far away from the ear. The screen background light causes unnecessary waste of power

In addition, in order to avoid electromagnetic wave radiation or other reasons, the user may artificially keep the mobile phone away from the brain for a certain distance before making a call. This distance may exceed the fixed distance detected by the distance sensor, which may also cause the screen backlight to light up.

At this time, not only the power of the touch screen mobile phone is still wasted, but also the user may touch the hook button of the touch screen mobile phone and hang up by mistake

[0005] In short, when the background technology adjusts the screen brightness of a touch-screen mobile phone, the use of a distance sensor will inevitably cause the phenomenon that the screen background light is turned on by mistake, so the effect of the background technology on saving the power of the touch-screen mobile phone is not enough. Obviously, further, it will also cause the user to hang up by mistake
