In order to make the object, technical solution and advantages of the present invention clearer, specific embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only parts related to the present invention are shown in the drawings but not all content. Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe various operations (or steps) as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure.

Embodiment one

Fig. 1 has provided the flow chart of the control method of the mobile terminal screen state provided by Embodiment 1 of the present invention, the method of this embodiment can be carried out by the control device of mobile terminal screen state, and this device can be through hardware and/or software In this way, the device can be set inside the mobile terminal as a part of the mobile terminal.

As shown in Figure 1, the method for controlling the screen state of a mobile terminal provided in this embodiment specifically includes the following steps:

Step 101, determine that the foreign object interference event of the current terminal is triggered.

The terminals described in this embodiment include but are not limited to mobile phones, notebooks, tablet computers and other devices provided with proximity sensors.

During the process of talking on the terminal or preventing false touches, it is inevitable that foreign objects will get on the screen of the terminal. If there is a protective film on the screen corresponding to the proximity sensor of the terminal or the screen corresponding to the proximity sensor of the terminal Oil, sweat, cosmetics, etc., will affect the terminal's control of the screen status. The screen state includes a screen off state and a screen on state.

When it is detected that there is a foreign object on the screen of the proximity sensor of the current terminal, it can be determined that the foreign object interference event of the current terminal is triggered.

Step 102, adjust the proximity threshold and the distance threshold of the proximity sensor of the current terminal according to a set adjustment rule.

The most common proximity sensors configured in mobile terminals include infrared proximity sensors. The infrared proximity sensor emits infrared rays outward, and then judges the distance between the object and the sensor by measuring the intensity of the infrared rays reflected back by the object. The stronger the intensity of the received infrared light, the smaller the distance between it and the object. The infrared proximity sensor will convert the measured infrared intensity into a measurement value that is directly proportional to it. This measurement value can be called the proximity value. The larger the proximity value obtained by the infrared proximity sensor, the closer the distance between it and the object. small. Generally, the proximity value may be an output value of an analog-to-digital converter (Analog-to-Digital Converter, ADC) in the infrared proximity sensor, referred to as an ADC value or an AD value.

Before the terminal uses the proximity sensor to control the screen state, the proximity threshold and the distance threshold will be preset. When the proximity value of the proximity sensor is greater than the proximity threshold, it will be judged as a proximity state and the touch screen will be turned off; When the threshold is reached, it is judged to be far away, and the touch screen is lit.

When the current terminal is disturbed by foreign objects, the proximity value of the proximity sensor will change. For example, the distance threshold is 400, and the proximity threshold is 450. After the terminal is disturbed by oil pollution, the proximity value of the proximity sensor will increase the oil pollution value by 100. Then, if the standard proximity value without oil pollution interference is 320, because it is less than the distance threshold The screen will be turned on, but the actual proximity value becomes 420 after being disturbed by oil pollution. Since 420 is not less than the distance threshold, the screen will not be turned on, which will lead to the problem that the screen is not turned on when the screen should be turned on. This will seriously affect the user experience; if the standard proximity value without oil pollution interference is 380, the screen will not be turned off because it is not greater than the proximity threshold of 450, but the actual proximity value becomes 480 after being disturbed by oil pollution, because 480 is greater than the proximity threshold 450 will turn off the screen, which will cause the screen to be turned off when it should not be turned off, seriously affecting the user experience.

After determining that the current terminal is interfered by foreign objects, adjust the proximity threshold and the distance threshold of the proximity sensor of the current terminal according to the set adjustment rules, so that the adjusted proximity threshold and distance threshold are suitable for the screen state of the mobile terminal with foreign object interference control.

Step 103. Control the screen state of the current terminal according to the adjusted proximity threshold and the adjusted distance threshold.

The acquired proximity value of the proximity sensor is compared with the adjusted proximity threshold and the adjusted distance threshold, and when the proximity value is greater than the proximity threshold, the screen is turned on; when the proximity value is smaller than the distance threshold, the screen is turned off.

In the method provided in this embodiment, after determining that the current terminal is interfered by foreign matter such as oil, adjust the proximity threshold and the distance threshold of the proximity sensor according to the set adjustment rules, and control the terminal according to the adjusted proximity threshold and the adjusted distance threshold. The current screen state of the terminal avoids the problem that the mobile terminal still adopts the original approach threshold and far away threshold after being interfered by foreign objects, which leads to the problem that the mobile terminal cannot accurately control the screen state, optimizes the existing screen state control method, and improves The accuracy of the screen state control.

On the basis of the above technical solution, it further includes: if it is detected that the foreign object interference event of the current terminal is not triggered, maintaining the original proximity threshold and the original distance threshold.

Embodiment two

FIG. 2 shows a flowchart of a method for controlling a screen state of a mobile terminal provided by Embodiment 2 of the present invention. This embodiment is optimized on the basis of the first embodiment above. In this embodiment, the optimization of "determining that the foreign object interference event of the current terminal is triggered" is: determining that the acquisition event of the maximum value of the proximity sensor of the current terminal is triggered; Time and the second time from the maximum value of the proximity sensor to the set value in the away state; if the difference between the second time and the first time is greater than the standard error value, it is determined that the foreign object interference event of the current terminal is triggered.

Correspondingly, as shown in Figure 2, the method provided in this embodiment includes the following steps:

Step 201. Determine that the event of acquiring the maximum value of the proximity sensor of the current terminal is triggered.

When the terminal is close to the user's skin, the value of the proximity sensor is the largest. If the value of the proximity sensor reaches the maximum value during the call, it may be interfered by foreign objects such as oil, otherwise, it will not be interfered by foreign objects such as oil.

Step 202. Obtain the first time from the set value to the maximum value of the proximity sensor in the close state and the second time from the maximum value of the proximity sensor to the set value in the far away state.

Wherein, the set value is a preset value close to the maximum value of the proximity sensor, for example, the maximum value of the proximity sensor is 1023, then the set value can be any value between 800-900, for example, the value is 900 . As long as the terminal has a change in distance, the proximity sensor can easily reach the set value.

The close state is the state in which the proximity value of the proximity sensor is in the process of changing from the set value to the maximum value, and the far state is the state in which the proximity value of the proximity sensor is in the process of changing from the maximum value to the set value. state. Exemplarily, the terminal is in the proximity state during the process of gradually changing the proximity value of the proximity sensor from 900 to 1023, and the terminal is in the far state of the process of gradually changing the proximity value of the proximity sensor from 1023 to 900.

Step 203 , judging whether the difference between the second time and the first time is greater than the standard error value, if yes, execute step 204 , otherwise execute step 207 .

Step 204, determine that the foreign object interference event of the current terminal is triggered.

Generally, if there is no foreign object interference in the terminal, the difference between the first time and the second time should be within the standard error range, and if the difference between the second time and the first time is greater than the standard error value, it means The terminal has been interfered by a foreign object. Furthermore, according to the relationship between the second time and the first time, the degree to which the terminal is interfered can be determined.

Step 205, adjust the proximity threshold and the distance threshold of the proximity sensor of the current terminal according to the set adjustment rule.

Specifically, the proximity threshold and the distance threshold of the proximity sensor of the current terminal may be adjusted according to the relationship between the second time and the first time.

Step 206: Control the screen state of the current terminal according to the adjusted proximity threshold and the adjusted distance threshold.

Step 207. Keep the original proximity threshold and the original distance threshold of the current terminal.

The method provided in this embodiment first determines that the proximity sensor of the current terminal has reached the maximum value, and then according to the first time from the set value to the maximum value of the proximity sensor in the close state and from the maximum value of the proximity sensor to the set value in the far away state to determine that the current terminal is interfered by a foreign object, and finally adjust the proximity threshold and the distance threshold of the proximity sensor of the current terminal according to the set adjustment rules, and control the terminal according to the adjusted proximity threshold and the adjusted distance threshold The current screen state of the terminal avoids the problem that the mobile terminal still adopts the original proximity threshold and distance threshold after being interfered by foreign objects, resulting in the mobile terminal being unable to accurately control the screen state, and optimizes the existing screen state control method. Improved the accuracy of screen state controls.

Embodiment three

FIG. 3 shows a flowchart of a method for controlling a screen state of a mobile terminal provided by Embodiment 3 of the present invention. This embodiment is optimized on the basis of the second embodiment above. In this embodiment, the optimization of "adjusting the proximity threshold and the distance threshold of the proximity sensor according to the set adjustment rule" is: according to the ratio or difference between the second time and the first time, determine the proximity A first adjustment value for the threshold and a second adjustment value for the distance threshold; increasing the proximity threshold by the first adjustment value, and increasing the distance threshold by the second adjustment value.

Correspondingly, as shown in Figure 3, the method provided in this embodiment includes the following steps:

Step 301. Determine that the event of acquiring the maximum value of the proximity sensor of the current terminal is triggered.

Step 302. Obtain the first time from the set value to the maximum value of the proximity sensor in the close state and the second time from the maximum value of the proximity sensor to the set value in the far away state.

Step 303 , judging whether the difference between the second time and the first time is greater than a standard error value, if yes, execute step 304 , otherwise execute step 308 .

Step 304, determine that the foreign object interference event of the current terminal is triggered.

Step 305: Determine a first adjustment value close to the threshold and a second adjustment value far away from the threshold according to the ratio or difference between the second time and the first time.

Wherein, the first adjustment value and the second adjustment value may be the same value or different values. The value range of the first adjustment value and the second adjustment value may be 100-200.

When the difference or ratio between the second time and the first time is relatively large, it means that the terminal is greatly disturbed by foreign objects, and the first adjustment value and the second adjustment value can be set to a larger value, such as 150, If the difference or ratio between the second time and the first time is relatively small, it means that the degree of foreign object interference to the terminal is relatively small, and the first adjustment value and the second adjustment value may be set to smaller values, such as 100. In this step, the first adjustment value close to the threshold and the second adjustment value away from the threshold are determined through the ratio or difference between the second time and the first time, and the adjustment values close to the threshold and away from the threshold can be determined quickly and accurately.

Step 306: Increase the proximity threshold by a first adjustment value, and increase the distance threshold by a second adjustment value.

Step 307. Control the screen state of the current terminal according to the adjusted proximity threshold and the adjusted distance threshold.

Step 308: Maintain the original proximity threshold and the original distance threshold of the current terminal.

In the method provided in this embodiment, after determining that the current terminal is interfered by a foreign object, according to the first time from the set value to the maximum value of the proximity sensor in the approaching state and the first time from the maximum value of the proximity sensor to the set value in the far away state A ratio or difference between two times, determining a first adjustment value for the proximity threshold and a second adjustment value for the distance threshold, increasing the proximity threshold by the first adjustment value, and increasing the distance threshold by a second adjustment value, according to the adjusted proximity threshold and the adjusted distance threshold to control the screen state of the current terminal, avoiding the mobile terminal still using the original proximity threshold and distance threshold after being interfered by foreign objects, resulting in the mobile terminal being unable to accurately control The problem of screen state optimizes the existing screen state control method and improves the accuracy of screen state control.
