Production cost.
The present embodiment also provides a kind of method of adjustment of screen intensity, as shown in figure 9, the method includes：
Second detected value of S101, the first detected value for obtaining the first receiver and the second receiver.
For example, in one embodiment, the detected value is light intensity value.Terminal can obtain the first of first receiver 22
Second light intensity value of light intensity value and the second receiver 24.It should be understood that the structure of first receiver and the second receiver can
With identical with the structure in above-described embodiment, or existing structure.
S102, calculate first detected value and the average value of second detected value.
For example, terminal calculates the average value of first light intensity value and second light intensity value.
S103, the average value and predetermined threshold value are compared, obtain comparative result.
For example, with predetermined threshold value be compared average value by terminal, terminal is also remote to judge that obstacle is close to.This is pre-
If threshold value can include presetting close to threshold value and presetting away from threshold value, this is preset close to threshold value and is preset away from threshold value more than this.Its
Middle step S103 can include：
S1031, judge the average value whether more than default close to threshold value.
For example, whether terminal judges have screen of the obstacle near terminal.Because when there is obstacle to be close to, transmitter is sent out
The light penetrated is blocked thing and is reflected back in cover plate, thus the light intensity value that receives of receiver more than default close to threshold value.Namely the
The average value of the light intensity value that one receiver or the second receiver are received is default close to threshold value more than this.If terminal judges that this is put down
More than default close to threshold value, then terminal performs S1032 to average.If terminal judges that the average value is default close less than or equal to this
Threshold value, then terminal can perform step S1033.
S1032, if it is determined that the average value is default close to threshold value more than this, it is determined that screen of the obstacle near terminal.
S1033, if it is determined that the average value is default close to threshold value less than or equal to this, then judge whether the average value is less than
Preset away from threshold value.
For example, when terminal judges no obstacle near terminal, terminal continues to determine whether obstacle away from screen.By
In obstacle away from when, the light of transmitter transmitting does not have a stop of obstacle, thus receiver can only receive it is little
Light, namely light intensity value is less than and presets away from threshold value.If terminal judges the average value less than default away from threshold value, terminal execution
S1034, if terminal judges that the average value is default away from threshold value more than or equal to this, terminal can be with return to step S1033.
S1034, if it is determined that the average value is default away from threshold value less than this, it is determined that screen of the obstacle away from terminal.
S104, the screen intensity of terminal is controlled according to the comparative result.
For example, comparative result of the terminal according to step S103, the brightness to screen is controlled, and the control is such as to extinguish
Or lighting operation.Specifically, step S104 can include：
S1041, when terminal is determined with obstacle near the screen of terminal, terminal extinguish screen.
For example, when terminal is determined with obstacle near terminal, terminal extinguishes screen, that is, the now brightness value of screen
It is minimum.
S1042, when terminal judge obstacle away from terminal screen when, then light screen.
For example, when terminal is determined with obstacle away from screen, end point bright screen curtain, namely terminal is by the brightness value of screen
Default display brightness is adjusted to by minimum.
Due to the existing detection method for detecting whether obstacle near screen, mainly entered by the data of single receiver
Row judges, therefore easily the situation of erroneous judgement occurs.
Although the above method is by taking optical signal as an example, the present invention can not be constituted and limited.The method of the present embodiment is same
Sample is applied to other kinds of signal.
