The principle of the current distance sensor is to emit infrared rays through infrared diodes, and after being reflected by close-range objects, the infrared detector can measure the distance by receiving the intensity of infrared rays. Generally, the effective distance is within 10cm. When the distance sensor detects that an object is close to the state, the touch screen of the electronic device is turned off, and when the distance sensor detects that the object is not close to the state, the touch screen of the electronic device is turned on.

However, the distance sensor is generally large in size and high in cost, and needs to open holes in the electronic device to emit and receive infrared rays. In the case of affecting the overall appearance of the electronic device, it is not convenient for the thin and light design of the electronic device.
