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.

First claim

a distance sensing module that is arranged below a display area of the screen module and includes an infrared receiver and a plurality of infrared emitters, wherein emitted energy of any one of the plurality of infrared emitters is less than the excitation threshold of the photoelectric effect unit and a sum of emitted energies of the plurality of infrared emitters is greater than an operating threshold of the distance sensing module.

2. The electronic device of claim 1 , wherein the distance sensing module further comprises a sensing body, and both the infrared receiver and the plurality of infrared emitters are integrated on the sensing body.

3. The electronic device of claim 1 , wherein the display area of the screen module comprises an edge area and the distance sensing module is arranged below the edge area.

4. The electronic device of claim 1 , wherein the infrared receiver and the plurality of infrared emitters are arranged in an array, and the infrared receiver is arranged adjacent to any one of the plurality of infrared emitters.

5. The electronic device of claim 1 , wherein the distance sensing module comprises one infrared receiver and the plurality of infrared emitters are arranged along a circumferential direction of the infrared receiver.

6. The electronic device of claim 5 , wherein the plurality of infrared emitters are distributed centrosymmetrically around the infrared receiver.

7. The electronic device of claim 1 , wherein the distance sensing module comprises a plurality of infrared receivers and each of the plurality of infrared receivers is associated with at least one infrared emitter.

8. The electronic device of claim 1 , wherein emitted energies of all of the plurality of infrared emitters are equal.

9. The electronic device of claim 1 , wherein emitted energies of at least two infrared emitters of the plurality of infrared emitters are different.

10. The electronic device of claim 1 , further comprising a device body, wherein the device body comprises at least one screen assembly surface and the display area of the screen module covers the screen assembly surface.

11. The electronic device of claim 1 , wherein the infrared receiver is arranged adjacent to at least two of the plurality of infrared emitters.

12. The electronic device of claim 7 , wherein a number of infrared emitters associated with one of the plurality of infrared receivers is different from that of infrared emitters associated with others of plurality of infrared receivers.

13. The electronic device of claim 7 , wherein the plurality of infrared receivers are arranged at different regions below the display area of the screen module.

14. The electronic device of claim 1 , further comprising a device body, wherein the device body comprises at least one screen assembly surface and the display area of the screen module covers a part of area of the screen assembly surface.
