Step 602, corresponding multiple current source groups are merged according to target current value and is opened, obtain middle reference electric current.
After obtaining target current value, multiple current sources are opened, by the combination of multiple current sources, obtain close target
The middle reference electric current of current value.
Step 603, it detects middle reference electric current and whether the difference of target current value is greater than preset difference value.
After obtaining middle reference electric current, its difference with target current value is detected.
Step 604, if more than then obtaining new current source group and merge and open, to reduce middle reference electric current and target electricity
The difference of flow valuve.
Increase, reduce or replace current source if difference is too big, so that difference reduces.If difference is very small,
It and can not also be smaller after adjusting, it is determined that the current source group is combined into immediate combination, and the electric current provided is closest to step
The electric current of rapid 501 the first obtained signals.
Step 5032, corresponding first photoelectric current is obtained according to second signal.

Infrared remote receiver obtains corresponding second photoelectric current according to third signal, and then in circuit, the first signal is turned
Change corresponding reference current into, the polarity of reference current and the second photoelectric current subtracts on the contrary, obtaining the second photoelectric current with reference to electricity
Then the second M signal is changed into digital signal by analog-digital converter ADC by the second M signal after stream, obtain
Two digital signal.
Step 506, approach signal is calculated according to the first digital signal and the second digital signal, and according to approach signal
Signal strength control display screen state.
Approach signal is calculated according to the first digital signal and the second digital signal, i.e. the first digital signal subtracts second
Digital signal obtains approach signal, is then converted to corresponding close distance according to approach signal, then according to close to distance
Control the state of display screen.For example, controlling when terminal is in voice call state the state of display screen.At this point, working as
When user face is close to display screen, it can control display screen extinguishing, maloperation caused to display screen to avoid user.When user's face
When portion is far from display screen, control display screen is lighted, to restore the normal display of display screen.
As shown in figure 12, Figure 12 is that the 4th kind of process of display screen condition control method provided by the embodiments of the present application is illustrated
Figure.Wherein, it may comprise steps of according to the state that the signal strength of approach signal controls display screen:

Threshold value.
Step 613, if the signal strength of approach signal is greater than signal strength threshold, display screen extinguishing is controlled.
Step 614, when display screen, which is in, puts out screen state, judge whether the signal strength of approach signal is less than signal strength
Threshold value.
Step 615, it if the signal strength of approach signal is less than signal strength threshold, controls display screen and lights.
One pre-determined distance, such as 5cm, corresponding one signal strength threshold of pre- distance setting are set.When display screen is in
When bright screen state, judge whether the signal strength of approach signal is greater than signal strength threshold, if more than illustrating to be less than close to distance
Pre-determined distance, terminal very little at a distance from face prevent maloperation at this point, control display screen extinguishes.
When display screen, which is in, puts out screen state, judge whether the signal strength of approach signal is less than signal strength threshold.If
It is less than, illustrates to be greater than pre-determined distance close to distance, terminal has become larger at a distance from face, then controlled display screen and light, convenient
User's operation display screen.
As shown in figure 13, Figure 13 is that the 5th kind of process of display screen condition control method provided by the embodiments of the present application is illustrated
Figure.Wherein, according to the signal strength of approach signal control display screen state can with the following steps are included:

Step 622, when display screen is in bright screen state, judge whether the signal strength of approach signal is greater than the first signal
Intensity threshold；
Step 623, if more than the first signal strength threshold, then display screen extinguishing is controlled；
Step 624, if less than the first signal strength threshold, judge the signal strength of approach signal whether less than the second letter
Number intensity threshold；
Step 625, if being less than second signal intensity threshold, display screen is kept to be in bright screen state；
Step 626, it if more than second signal intensity threshold, and less than the first signal strength threshold, then continuously acquires at least
Approach signal twice then controls display screen extinguishing when the signal strength for continuously acquiring approach signal at least twice becomes larger.
Setting signal intensity threshold, the signal strength threshold include the first signal strength threshold, and less than the first signal
The second signal intensity threshold of intensity threshold.It is default that first signal strength threshold and second signal intensity threshold respectively correspond first
Distance and the second pre-determined distance.
When display screen is in bright screen state, judge whether the signal strength of approach signal is greater than the first signal strength threshold
Value；If more than the first signal strength threshold, illustrate close to distance then to control display screen extinguishing less than the first pre-determined distance.If small
In the first signal strength threshold, illustrate whether approach the signal strength that approach signal is then judged apart from the first pre-determined distance is greater than
