Detailed description of the invention
In order to make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing the present invention made intoOne step ground describes in detail, it is clear that described embodiment is only some embodiments of the present invention rather than whole enforcementExample.Based on the embodiment in the present invention, those of ordinary skill in the art are obtained under not making creative work premiseAll other embodiments, broadly fall into the scope of protection of the invention.
As it is shown in figure 1, be a kind of method of information processing in the embodiment of the present invention, the method includes:
Step 101: terminal by range sensor the distance determined between current screen and shelter more than go out screen away fromFrom rear, it is judged that whether the capacitance of screen is less than predetermined capacitance；
Step 102: terminal determine the capacitance of screen less than predetermined capacitance, and after described screen is in bright screen, controlScreen processed goes out screen.
Wherein, range sensor is passed through in the distance determined between current screen and shelter not less than going out in described terminalBefore, described terminal is it needs to be determined that present terminal is in talking state to screen distance.
