As shown in FIG. 2, an embodiment of the present application provides a proximity detection method, which is applied to a terminal device, and the method may include the following steps 201 to 202.

Step 201: The terminal device obtains state information of the terminal device when it is determined according to the ultrasonic sensor of the terminal device that a first object within a first preset distance covers the terminal device.

The status information is used to determine whether the first screen of the terminal device is blocked by the first object.

Step 203: The terminal device judges whether the status information meets the target condition.

The target condition includes at least one of the following: the gravitational acceleration information is within a first range, and the angular velocity information is within a second range.

In the case where the terminal device determines that a first object obstructs the terminal device within the first preset distance, if the gravitational acceleration information is within the first range, it can be determined that the first object obstructs the first screen. The first range may be preset or acquired in real time, which is not limited in the embodiment of the present application. In the embodiment of the present application, if the gravitational acceleration information is within the first range, the state information meets the target condition.

In the case where the terminal device determines that a first object obstructs the terminal device within the first preset distance, if the angular velocity information is within the second range, it can be determined that the first object obstructs the first screen. The second range may be preset or acquired in real time, which is not limited in the embodiment of the present application. In the embodiment of the present application, if the angular velocity information is within the second range, the state information meets the target condition.

Exemplarily, the terminal device can calculate the posture and gesture action of the terminal device according to the state information of the terminal device (such as the three-axis gravity acceleration data of the mobile phone collected by the acceleration sensor and the three-axis angular velocity data collected by the gyroscope). Here, a gesture is defined And three gestures:

a) Pick up the terminal device and approach the ear gesture (referred to as the answer gesture for short);

b) Vertical placement posture (that is, the posture when the terminal device is placed near the ear);

c) The screen is up and down;

d) Unknown posture.

Combine the ultrasonic sensor to determine whether there is an object obstructing the terminal device within the first preset distance (yes if obstructed by an object, no obstructed by an object), and gesture posture information (status information) reported by the inertial sensor (gravity and gyroscope) , To determine whether there is an object blocking the first screen (Yes for blocking the first screen, No for not blocking the first screen), as shown in the following table.

According to the above table, it can be known that when the ultrasonic sensor determines that an object is blocking the terminal device, only when the terminal device is in the answering gesture or vertical posture, the first screen can be determined to be blocked.

When the state change information meets the target condition, the following step 204 is executed; when the state change information does not meet the target condition, the following step 205 is executed.

When the screen is turned on, the screen does not turn on when a call comes in or the terminal device lights up the screen due to a user's false trigger, thereby reducing power consumption. When the terminal device determines according to the infrared sensor that there is a second object blocking the first screen within the second preset distance, prohibit the first screen from lighting up the preset area in the off-screen state, and the preset area is used to display prompt information , When there is an object obstructing the first screen (indicating that the user does not need to view the prompt information), the display of prompt information in the off-screen state is prohibited (including the situation that the preset area in the current off-screen state is lit and the prompt information is displayed Cancel the display of the prompt information and extinguish the preset area), which can save power. Moreover, the approach of detecting the proximity of the screen with the infrared sensor in the off-screen state can improve the accuracy of the occlusion detection without damaging the life of the screen.
