Abstract
An electronic device including a screen module and a distance sensing module. The screen module includes a light emitting unit and a control circuit conductively connected with the light emitting unit, where when energy received by a photoelectric effect unit of the control circuit is greater than an excitation threshold of the photoelectric effect unit the control circuit is turned on and the light emitting unit emits light. The distance sensing module is arranged below a display area of the screen module and includes an infrared receiver and a plurality of infrared emitters, where emitted energy of any one of the plurality of infrared emitters is less than the excitation threshold and a sum of emitted energies of the plurality of infrared emitters is greater than an operating threshold of the distance sensing module.
