Fig. 3 is a flowchart of a method for controlling screen-off of a mobile terminal in an embodiment. As shown in fig. 3, a method for controlling screen-off of a mobile terminal includes:
In one embodiment, the proximity sensor is a sensor that detects without touching a detection object. When the mobile terminal is in a call, the proximity sensor monitors the emitted infrared rays to judge whether the mobile terminal is close to the face or not.
The designated times can be set according to needs, such as 5 times, 10 times and the like. The infrared energy value received by the proximity sensor for the specified times is the infrared energy value of the specified times of continuous sampling after the proximity sensor receives the infrared energy value according to a certain sampling frequency.
In one embodiment, the specified number of times may be greater than or equal to 2 times.
In one embodiment, the specified number of times may also be greater than or equal to 5 times.
An infrared transmitting end of a proximity sensor of the mobile terminal transmits an infrared light pulse signal, and a receiving end of the proximity sensor receives infrared light. When the barrier is close to the mobile terminal, infrared light is refracted, and after the infrared light is received by the receiving end of the proximity sensor, the infrared energy value is obtained through conversion by the analog-to-digital converter. When no object is shielded, the receiving end of the proximity sensor receives infrared light to obtain the minimum infrared energy value, when the object is close to, the detected infrared energy value is continuously increased, and when the object is close to the mobile terminal completely, the infrared energy value reaches the maximum value. When the object is away from the device slowly, the detected infrared energy value is reduced slowly, and when the object is not shielded completely, the detected infrared energy value is minimum.
According to the different internal settings of an Integrated Circuit (IC), the registers have differences of 8 bits, 10 bits, 12 bits, etc., and the ranges of the infrared energy values are different, which correspond to 256, 1024, 4096, etc. For example, in a 10-bit device, when there is no object block, the infrared energy value is 50, theoretically 0, no object block is emitted, but some infrared rays are diffracted from the inside to the receiving end, so that there is a certain low noise value. When an obstacle (such as a face) approaches slowly, the refracted infrared ray is stronger and stronger, and the received infrared ray is more and more, the infrared energy value is larger and larger, for example, the infrared energy value is 100-.
In one embodiment, the infrared energy values of the successive designated times can be sorted, then the maximum infrared energy value and the minimum infrared energy value are obtained according to the sorting result, and the difference value between the maximum infrared energy value and the minimum infrared energy value is obtained by subtracting the minimum infrared energy value from the maximum infrared energy value.
For example, the infrared energy values for 10 consecutive times are 20, 124, 50, 15, 510, 430, 120, 189, 451, 323, 51. Sorting the infrared energy values of 10 times in succession from large to small results in the sorting results 510, 451, 430, 323, 189, 124, 120, 51, 50, 15. The maximum ir energy value is 510, the minimum ir energy value is 15, and the difference between the maximum ir energy value 510 and the minimum ir energy value 15 is 495.
And 306, switching the screen-off control mode into an anti-interference mode when detecting that the difference value between the maximum infrared energy value and the minimum infrared energy value is greater than a first energy threshold value, wherein the anti-interference mode is to configure the screen-off threshold value as a preset infrared energy value for controlling screen-off.
In one embodiment, the first energy threshold may be set as desired. For example, if the first energy threshold is 50 and the difference 495 is greater than 50, the screen-off control mode is switched to enter the anti-interference mode, that is, the screen-off threshold is configured to be a preset infrared energy value for controlling screen-off. The preset infrared energy value for controlling the screen to be extinguished is a larger infrared energy value. The preset infrared energy value for controlling screen-off is large, so that even if the data jitter is severe, the screen-off and screen-flashing can not be carried out. The preset infrared energy value for controlling the screen-off may be 1000, etc. The screen off means that the screen of the mobile terminal is off and corresponding operation cannot be carried out. When the infrared energy value is detected to be larger than the preset infrared energy value for controlling screen extinguishing, the mobile terminal can be switched from the bright screen to the screen extinguishing. The bright screen means that the screen of the mobile terminal is lighted, information can be viewed or operated, and the like.
According to the control method for extinguishing the screen of the mobile terminal, the difference value between the maximum infrared energy value and the minimum infrared energy value is obtained by obtaining the infrared energy values of the continuous appointed times, and when the difference value between the maximum infrared energy value and the minimum infrared energy value is detected to be larger than the first energy threshold value, the screen extinguishing threshold value is configured to be the preset infrared energy value for controlling the screen extinguishing, so that the screen extinguishing control mode enters the anti-interference mode, when the data jitter occurs to the detected infrared energy value in the ultra-strong light environment, the conditions of screen extinguishing and continuous screen lightening change can not occur, and the screen flickering is avoided.
In an embodiment, the method for controlling the screen of the mobile terminal to be turned off further includes: and acquiring the maximum infrared energy value in the infrared energy values received by the proximity sensor within the appointed time, and taking the maximum infrared energy value as the preset infrared energy value for controlling screen extinguishing. The designated time may be set as desired, such as half an hour or the like.
In an embodiment, the method for controlling the screen of the mobile terminal to be turned off further includes: detecting that the difference value between the maximum infrared energy value and the minimum infrared energy value is not greater than a first energy threshold value, and judging whether the difference value between the infrared energy values of two adjacent times in the infrared energy values of the continuous specified times is greater than a second energy threshold value or not; and if the difference between the two adjacent infrared energy values in the infrared energy values of the continuous designated times is larger than a second energy threshold value, switching the screen-off control mode to enter an anti-interference mode.
In one embodiment, it is further determined whether the difference between the two adjacent infrared energy values is greater than the second energy threshold value. The second energy threshold may be less than the first energy threshold.
In an embodiment, the method for controlling the screen of the mobile terminal to be turned off further includes: judging whether the difference between the infrared energy values of two adjacent times does not exist in the infrared energy values of the continuous appointed times is larger than a second energy threshold value, and judging whether the infrared energy values of the continuous appointed times are all larger than a first screen-off threshold value; and if the infrared energy values of the continuous appointed times are all larger than a first screen-off threshold value, switching a screen-off control mode into an anti-interference mode.
In one embodiment, the first de-latching threshold is less than a predetermined infrared energy value used to control de-latching. For example, the first screenout threshold may be 300, 350, etc.
In an embodiment, the method for controlling the screen of the mobile terminal to be turned off further includes: and detecting the frequency of the interference light, and controlling the receiving frequency of the proximity sensor in the mobile terminal to be smaller than the frequency of the interference light.
In one embodiment, the frequency of the interference source is collected by a sampling device to obtain the frequency of the interference light. The receiving frequency of the proximity sensor is controlled to be smaller than the frequency of the interference light, and the receiving frequency of the proximity sensor can be controlled by controlling the receiving interval time of the proximity sensor. The longer the reception interval time, the smaller the reception frequency. The receiving interval time refers to the time interval between two adjacent times of receiving infrared rays by the proximity sensor.
In one embodiment, the receiving frequency of the proximity sensor is controlled to be lower than the frequency of the interference light, and the control can be performed by a switch, that is, the frequency of the receiving signal of the proximity sensor is controlled by the switch, when the switch is in an open state, the proximity sensor receives the signal, and when the switch is in a closed state, the proximity sensor cannot receive the signal.
Because interference sources such as strong light and the like generate frequency of interference light, the detected infrared energy value jumps, so that the mobile terminal has a screen flickering phenomenon.
In one embodiment, the detecting the frequency of the disturbing light and controlling the frequency of the proximity sensor in the mobile terminal to be less than the frequency of the disturbing light comprises: detecting the frequency of an interference source, acquiring the frequency of the minimum interference light in the frequency of the interference source, and controlling the receiving frequency of a proximity sensor in the mobile terminal to be smaller than the frequency of the minimum interference light.
In one embodiment, because the frequency of the interference light generated by the interference source is not stable, when a plurality of frequencies of the interference source are detected, the frequency of the minimum interference light of the interference source frequency is selected, and the receiving frequency of the proximity sensor of the mobile terminal is controlled to be smaller than the frequency of the minimum interference light. By controlling the receiving frequency of the proximity sensor to be smaller than the frequency of the minimum interference light, the influence of the frequency of the interference light on the detection result can be further reduced, and the occurrence probability of screen flashing is reduced.
