202. The distance value is detected by a distance sensor.
The electronic equipment transmits a detection signal towards the display screen by controlling the distance sensor, the detection signal passes through the display screen and is transmitted to the outside, a reflection signal is formed after the detection signal is reflected by an external object, the reflection signal passes through the display screen and enters the distance sensor, and the electronic equipment can determine a distance value according to the time difference from the transmission of the detection signal by the distance sensor to the reception of the reflection signal. Or the distance value may be determined from the degree of attenuation of the signal.
In some embodiments, the display area of the display screen includes a status bar area, the status bar area is used for displaying a small bar area of information such as power information and alarm information of the electronic device, the probability that a regular user touches the status bar area is small, and the display pixels of the status bar area can be lower than those of other areas on the display screen, so that a signal can better pass through the status bar area. The orthographic projection of the distance sensor on the display screen can be located in the status bar area, namely the distance sensor is arranged below the status bar area, and the step of detecting the distance value through the distance sensor can comprise the following steps:
(1) controlling the distance sensor to emit a detection signal towards the direction of the status bar area, wherein the detection signal passes through the status bar area and is transmitted to the outside, and the detection signal is reflected by an external object to form a reflection signal, and the reflection signal passes through the status bar area and enters the distance sensor;

And when the distance value is larger than the critical value, judging that the distance state between the display screen and the external object is a far state.
In some embodiments, the step of determining the distance state between the display screen and the external object according to the distance value may include:
(1) comparing the distance value with a preset threshold value, and determining the size relationship between the distance value and the preset threshold value;
(2) when the distance value is smaller than the preset threshold value, determining that the distance state between the display screen and the external object is a close state;
(3) and when the distance value is larger than the preset threshold value, determining that the distance state between the display screen and the external object is a far state.

When the distance value is larger than the preset threshold value, the fact that the distance between the display screen and the external object is far is indicated, and the distance state between the display screen and the external object is determined to be a far state.
204. And controlling the state of the display screen according to the distance state.
The state of the display screen comprises a use state after the display screen is lightened and a standby state when the display screen is turned off. When the electronic equipment is in a standby state, when the distance state between the display screen and an external object is in a close state, the display screen is in a shielded state, the triggering operation of the preset key can not be responded, the electronic equipment continues to be in the standby state, the power consumption of the electronic equipment can be saved, and in addition, the misoperation caused by the fact that the display screen is lightened by mistake can be avoided. When the electronic equipment is in a standby state and the distance state between the display screen and an external object is a far state, the display screen is not in a shielded state, and the display screen can be lightened to enter a desktop or unlock an interface in response to the triggering operation of a preset key.
In some embodiments, the controlling the state of the display screen according to the distance state may include:
(1) when the distance state is the approaching state, controlling the display screen to be in a screen-off state;
(2) and when the distance state is the far state, controlling the display screen to light.
