Abstract

The disclosure relates to an electronic device. The electronic device includes: a shell, a display panel, the display panel or the shell including a light-transmitting area, an ambient light sensor, an infrared transmitter and a light guiding piece. The light guiding piece includes a light incident end and a light emitting end, the light incident end being configured to face the light-transmitting area, and the light emitting end being configured to face the ambient light sensor and the infrared transmitter.

First claim

What is claimed is:

1. An electronic device, comprising:
a shell;
a display panel, wherein the display panel or the shell comprises a light-transmitting area;
an ambient light sensor;
an infrared transmitter; and
a light guiding piece comprising a light incident end and a light emitting end, wherein the light incident end is configured facing the light-transmitting area, and the light emitting end is configured facing the ambient light sensor and the infrared transmitter,

wherein the light guiding piece comprises:
a light-shielding body comprising a first mounting hole and a second mounting hole;
a first light guiding column arranged in the first mounting hole, wherein a first end of the first light guiding column is configured facing the ambient light sensor, and a second end of the first light guiding column is configured facing the transparent area; and
a second light guiding column arranged in the second mounting hole, wherein a first end of the second light guiding column is configured facing the infrared transmitter, and a second end of the second light guiding column is configured facing the transparent area.

2. The electronic device of claim 1 , wherein the ambient light sensor and the infrared transmitter share a light guiding channel of the light guiding piece.

3. The electronic device of claim 1 , wherein the ambient light sensor and the infrared transmitter respectively correspond to different light guiding channels of the light guiding piece.

4. The electronic device of claim 1 , wherein the light guiding piece further comprises a light guiding seat body connected with the shell, wherein the light guiding seat body is respectively connected with the first light guiding column, the second light guiding column and the light-shielding body, and the ambient light sensor and the infrared transmitter are located on a side, facing away from the first light guiding column and the second light guiding column, of the light guiding seat body.

5. The electronic device of claim 4 , wherein the light guiding seat body comprises a mounting groove recessed from a side facing away from the light-shielding body, and the ambient light sensor and the infrared transmitter are located in the mounting groove.

6. The electronic device of claim 1 , wherein the light-shielding body comprises a non-light-transmitting polycarbonate light-shielding body.

7. The electronic device of claim 1 wherein the first light guiding column and the second light guiding column respectively comprise a light-transmitting acrylic light guiding column.

8. The electronic device of claim 1 ,
wherein the light guiding piece comprises a shared part, a first light guiding sub-part and a second light guiding sub-part,
wherein the first light guiding sub-part and the second light guiding sub-part are connected to a first end of the shared part and extend in different directions, and a second end of the shared part is configured facing the light-transmitting area,
wherein an ambient light path and an infrared light path on the shared part are physically isolated, and
wherein the first light guiding sub-part is configured facing the ambient light sensor, and the second light guiding sub-part is configured facing the infrared transmitter.

9. The electronic device of claim 8 , wherein the shared part comprises a light-shielding boundary layer comprising a first edge and two opposing second edges, wherein the first edge is located between the first light guiding sub-part and the second light guiding sub-part, and the second edge extends in a height direction of the shared part until to be at least flush with a surface of the shared part.

10. The electronic device of claim 8 , wherein a sectional area of the first light guiding sub-part decreases progressively from an end close to the shared part to an end away from the shared part.

11. The electronic device of claim 8 , wherein the second light guiding sub-part comprises an arc-shaped surface located on a side away from the first light guiding sub-part of the second light guiding sub-part, and an emission direction of the infrared transmitter points to the arc-shaped surface from an end away from the shared part of the second light guiding sub-part.

12. The electronic device of claim 8 , wherein the shared part comprises a polycarbonate light-transmitting shared part.

13. The electronic device of claim 8 , wherein the first light guiding sub-part comprises a visible light guiding sub-part, and the second light guiding sub-part comprises an infrared light guiding sub-part.

14. The electronic device of claim 1 , wherein the light guiding piece comprises an integrated light guiding column capable of transmitting infrared light and visible light, wherein the integrated light guiding column comprises:
a first lens part arranged on the light emitting end, wherein the first lens part faces the ambient light sensor, and
a second lens part arranged on the light emitting end, wherein the second lens part faces the infrared transmitter.

15. The electronic device of claim 14 , wherein in a height direction of the integrated light guiding column, a height difference between the first lens part and the second lens part is greater than zero.

16. The electronic device of claim 14 , wherein an end facing the ambient light sensor 3 is at the same height as the infrared transmitter 4 of the integrated light guiding column.
