As shown in figure 9, display screen condition control method may comprise steps of：

S510, signal projector repeatedly launch the first detectable signal with the first power, and signal receiver is according to each first Detectable signal obtains corresponding first signal strength values.

Wherein, terminal can be when needing the state to display screen to be controlled, and control signal transmitter is with the first power Repeatedly the first detectable signal of transmitting.For example, when terminal is in voice call state, the state of display screen is controlled.This When, when user face is close to display screen, it can be extinguished with control display screen, maloperation is caused to display screen to avoid user.When When user face is away from display screen, control display screen is lighted, to recover the normal display of display screen.

Wherein, the first power can be less power.Terminal can be controlled by the electric current of control signal transmitter The power of the signal projector.For example, terminal can be using the electric current of control signal transmitter as 10mA, the signal transmitting at this time The power of device is the first power.

First detectable signal is the signal projector with the detectable signal of first power emission.First detection Signal can be infrared ray.When signal projector launches the first detectable signal, outwards launched with the direction towards terminal display screen Detectable signal.

Wherein, after signal projector launches the first detectable signal, signal receiver detects the signal strength received at this time Value.The signal strength values received at this time are the first signal strength values.

First detectable signal is signal projector with the first power emission, i.e., with smaller power transmitting, the first detection In terminal inner diffraction occurs for signal, and diffracted signal is entered directly into signal receiver.First signal strength values are The intensity for the diffracted signal that signal receiver receives at this time.

In practical application, infrared transmitter and infrared remote receiver by perforate size due to being influenced, easily to terminal Detection accuracy impacts.And the first detectable signal be signal projector with the first power emission, i.e., sent out with smaller power Penetrate, may cause the first detectable signal that diffraction all occurs in terminal inner, the first detectable signal can not be from display screen at this time Interior sensor photosensitive field emission to the external world.

Wherein it is possible in the production process of terminal, terminal is debugged so that with the spy of first power emission Survey signal and diffraction all occurs in terminal inner, namely under first power, the signal of signal projector transmitting cannot be sent out It is mapped to the external world.

S520, the first averaged magnitude value is obtained according to multiple first signal strength values.

Wherein, multiple first signal strength values that terminal-pair obtains are calculated, to obtain multiple first signal strength values Average value so that obtain data it is more accurate.

S530, the signal projector with the second power repeatedly transmitting the second detectable signal, the signal receiver according to Each second detectable signal obtains corresponding secondary signal intensity level.

Wherein, after terminal gets the first averaged magnitude value, signal projector described in terminal control is with the second power Repeatedly the second detectable signal of transmitting.Second power is relatively high power, and second power is more than first power.Example Such as, terminal can be using the electric current of control signal transmitter as 50mA, and the power of the signal projector is the second power at this time.

Second detectable signal is the signal projector with the detectable signal of second power emission.Second detection Signal can be infrared ray.When signal projector launches the second detectable signal, outwards launched with the direction towards terminal display screen Detectable signal.

It should be noted that the operating current of signal projector can be pulse current.Terminal can first give the signal Transmitter inputs a less pulse current, to launch the first detectable signal；Then, one is inputted to the signal projector Larger pulse current, to launch the second detectable signal.So as to which the signal projector launches first detectable signal and institute The time interval stated between the second detectable signal is very short, such as can be 5ms (millisecond).

Wherein, after signal projector launches the second detectable signal, signal receiver detects the signal strength received at this time Value.The signal strength values received at this time are secondary signal intensity level.

Second detectable signal is signal projector with the second power emission, i.e., with relatively high power transmitting, the second detection In terminal inner diffraction occurs for a part for signal, and the diffracted signal of generation is entered directly into signal receiver.It is in addition, described The another part of second detectable signal by the sensor photosensitive field emission in display screen to the external world, through exterior object (example Such as, user face) reflection after form reflected signal, reflected signal is entered in signal receiver.Therefore, the secondary signal is strong The sum of the intensity for the diffracted signal that angle value receives at this time for signal receiver and the intensity of extraneous reflected signal.

S540, secondary signal average intensity value is obtained according to multiple secondary signal intensity levels.

Wherein, multiple secondary signal intensity levels that terminal-pair obtains are calculated, to obtain multiple secondary signal intensity levels Average value so that obtain data it is more accurate.

S550, the 3rd signal strength is calculated according to the first averaged magnitude value and secondary signal average intensity value Value.

Wherein, after terminal gets the first averaged magnitude value and secondary signal average intensity value, according to described First averaged magnitude value and secondary signal average intensity value calculate the 3rd signal strength values.3rd signal strength values are After signal projector is transmitted to the external world, the intensity through reflected signal caused by exterior object (for example, user face) reflection.

S560, according to the state of the 3rd signal strength values control display screen.

Wherein, after terminal calculates the 3rd signal strength values, you can according to the 3rd signal strength values control display screen State.For example, when terminal is in voice call state, the state of display screen is controlled.At this time, when user face pastes It during nearly display screen, can be extinguished with control display screen, maloperation is caused to display screen to avoid user.When user face is away from display During screen, control display screen is lighted, to recover the normal display of display screen.

In certain embodiments, as shown in Figure 10, step S510, signal projector with the first power, repeatedly visit by transmitting first Survey before signal, it is further comprising the steps of：

S570, obtains current environment light intensity value；

Step S510, signal projector repeatedly launches the first detectable signal with the first power, comprises the following steps：

S511, corresponding first performance number is obtained according to the current environment light intensity value, and signal projector is with described the Repeatedly the first detectable signal of transmitting, signal receiver obtain corresponding first to one performance number according to each first detectable signal Signal strength values.

Wherein, terminal can obtain current environment light intensity value before with the first power repeatedly the first detectable signal of transmitting, And matched prestoring environmental light intensity angle value in the terminal with the first power match table, to obtain corresponding first Performance number.It should be noted that multiple environmental light intensity angle value are preset in the environmental light intensity angle value and the first power match table, And corresponding one first performance number of each environmental light intensity angle value, so that signal projector is with the repeatedly transmitting the of the first power One detectable signal avoids the influence of ambient light closer to true environment.

In certain embodiments, as shown in Figure 10, step S510, signal receiver according to each first detectable signal It is further comprising the steps of after obtaining corresponding first signal strength values：

S580, calculates the difference of continuous multiple first signal strength values and default first signal strength values respectively；

If each difference is respectively less than predetermined threshold value, the first signal is obtained according to multiple first signal strength values Average intensity value.

After signal receiver gets continuous multiple first signal strength values, terminal is by each first signal strength values and in advance If the first signal strength values are compared, to judge that the difference of each first signal strength values and default first signal strength values is It is no to be less than predetermined threshold value.It should be noted that it is mentioned here it is continuous it is multiple can be configured as needed, such as：Continuous three A first signal strength values, are not limited herein.

Wherein, preset signal strength value can be the corresponding preferable letter of each first performance number pre-set in the terminal Number intensity level.Predetermined threshold value can be the first signal strength values and the acceptable error scope of the difference of ideal signal intensity level.

When judging that each difference is respectively less than predetermined threshold value, terminal will be obtained according to multiple first signal strength values Take the first averaged magnitude value.When judging that at least one difference is not less than predetermined threshold value, then continue to obtain continuous more A first signal strength values.

In certain embodiments, as shown in Figure 10, step S550, believed according to the first averaged magnitude value and second Number average intensity value calculates the 3rd signal strength values, comprises the following steps：

S551, calculates the difference of the secondary signal average intensity value and the first averaged magnitude value；

S552, is determined as the 3rd signal strength values by the difference.

Wherein, after terminal gets the first averaged magnitude value and secondary signal average intensity value, described second is calculated The difference of averaged magnitude value and the first averaged magnitude value.Since the first averaged magnitude value is that signal projector exists When launching detectable signal under smaller power, signal strength values that signal receiver is got, and secondary signal average intensity value is When signal projector launches detectable signal under relatively high power, signal strength values that signal receiver is got, therefore described Binary signal average intensity value is greater than the first averaged magnitude value, namely the difference is necessarily more than zero.

Then, the difference being calculated is determined as the 3rd signal strength values by terminal.

In certain embodiments, as shown in Figure 10, step S560, according to the 3rd signal strength values control display screen It is further comprising the steps of before state：

S590, obtains signal strength threshold；

Step S560, according to the state of the 3rd signal strength values control display screen, comprise the following steps：

S561, the state of the display screen is controlled according to the 3rd signal strength values and the signal strength threshold.

Wherein, after the 3rd signal strength values are calculated in terminal, signal strength threshold can be obtained.The signal strength threshold Value can be the signal strength values prestored in the terminal.The signal strength threshold is used to judge terminal and exterior thing In proximity state or away from state between body, so as to be controlled to the state of terminal display screen.

Then, terminal is according to the 3rd signal strength values and the state of the signal strength threshold control display screen.

In certain embodiments, as shown in figure 11, it is step S561, strong according to the 3rd signal strength values and the signal The state that threshold value controls the display screen is spent, is comprised the following steps：

S5611, when display screen is in bright screen state, judges whether the 3rd signal strength values are more than first threshold；

S5612, if the 3rd signal strength values are more than the first threshold, controls the display screen to extinguish.

Wherein, the signal strength threshold that terminal is got includes first threshold.The first threshold can be high threshold.Institute State high threshold to be used for when display screen is in bright screen state, triggering control display screen is extinguished.

When the display screen of terminal is in bright screen state, after terminal gets the first threshold, will be calculated the 3rd Signal strength values are compared with the first threshold, to judge whether the 3rd signal strength values are more than first threshold Value.When judging that the 3rd signal strength values are more than the first threshold, illustrate terminal with exterior object (for example, user Face) between be in proximity state, at this time control display screen extinguish.When judging that the 3rd signal strength values are less than or equal to During the first threshold, illustrate to be not in proximity state between terminal and exterior object (for example, user face), terminal is tieed up at this time Hold display screen and be in bright screen state.

For example, first threshold be 243.9, the 3rd signal strength values that terminal is got be 400, then at this time it is described 3rd letter Number intensity level is more than the first threshold, then terminal control display screen extinguishes.

In certain embodiments, as shown in figure 12, it is step S561, strong according to the 3rd signal strength values and the signal The state that threshold value controls the display screen is spent, is comprised the following steps：

S5613, when display screen, which is in, puts out screen state, judges whether the 3rd signal strength values are less than second threshold；

S5614, if the 3rd signal strength values are less than the second threshold, controls the display screen to light.

Wherein, the signal strength threshold that terminal is got includes second threshold.The second threshold can be Low threshold.Institute State Low threshold to be used for when display screen is in and puts out screen state, triggering control display screen is lighted.For in same external environment Same portion's terminal, the Low threshold is less than above-mentioned high threshold.
