Display device and vehicle detection system including thereof

Abstract

This invention provides a display device and a carrier detection system including the display device. The display device includes a backlight module, a display panel, a frame, and a light source. The backlight module includes a circuit board and a plurality of light-emitting units disposed on the circuit board; the display panel has a light-incident surface facing the backlight module; the frame is disposed on at least one side of the backlight module and at least partially supports the display panel, wherein the frame has adjacent sidewalls and a light-guiding portion, the light-guiding portion including a light-incident end and a light-emitting end; the light source is disposed adjacent to the light-incident end for emitting light, the light being introduced by the light-incident end and exported by the light-emitting end.

Claims

1. A display device, comprising: A backlight module includes a circuit board and a plurality of light-emitting units disposed on the circuit board; A display panel having a light-incident surface facing the backlight module; a frame disposed on at least one side of the backlight module and at least partially supporting the display panel, wherein the frame has an adjacent sidewall and a light guide portion, the sidewall having a notch, the light guide portion being disposed in the notch, and the light guide portion including a light-incident end and a light-outcident end; a light source disposed adjacent to the light-incident end for emitting light, wherein the light is introduced by the light-incident end and exported by the light-outcident end.

2. The display device as claimed in claim 1, wherein the sidewall and the light guide portion are made of different materials.

3. The display device as described in claim 2 further comprises a light-blocking material disposed on one side of the light guide portion facing the interior of the backlight module.

4. The display device as claimed in claim 1, wherein the sidewall includes a protrusion adjacent to the notch, the light guide portion includes a body and a side portion located on one side of the body, the side portion having a through hole, and the protrusion passing through the through hole to fix the sidewall and the light guide portion.

5. The display device as claimed in claim 1, wherein the sidewall is bonded to the light guide portion.

6. The display device as claimed in claim 1 further comprises a light-blocking material disposed on one side of the light-guiding portion away from the interior of the backlight module.

7. The display device as claimed in claim 1, wherein the light-incident end of the light-guiding portion extends through the plane of the display panel in a direction pointing towards the light-outcident end.

8. The display device as claimed in claim 1, wherein the thickness of the light guide portion is greater than the thickness of the sidewall in one direction parallel to the plane of the display panel and perpendicular to the extension direction of the frame.

9. The display device as claimed in claim 1, wherein the height of the light guide portion is less than the height of the sidewall in the extending direction from the light-incident end to the light-exit end of the light guide portion.

10. The display device as claimed in claim 1, wherein the light-emitting end of the light guide portion has a light path adjustment structure.

11. The display device as claimed in claim 10, wherein the optical path adjustment structure includes an inclined surface that is inclined relative to the plane on which the display panel is located.

12. The display device as claimed in claim 10, wherein the optical path adjustment structure includes an arc surface that protrudes outward relative to the light guide portion.

13. The display device as claimed in claim 1, further comprising a light source circuit board, the backlight module further comprising a base housing disposed on the side of the backlight module away from the display panel and adjacent to the frame, the light source circuit board being configured to at least partially overlap with the base housing and be close to the light-incident end of the light-guiding portion, and the light source being disposed on the light source circuit board.

14. The display device as claimed in claim 1, wherein the backlight module further comprises a bottom housing, the bottom housing comprising a back plate and a side plate adjacent to each other, the side plate being adjacent to the frame and having a slot near the back plate, the circuit board being disposed on the back plate and including a protruding end extending through the slot, and the light source being disposed on the protruding end; wherein, in a direction through the plane of the display panel, the height of the slot is less than the height of the side plate.

15. The display device as claimed in claim 1, wherein the backlight module further comprises a bottom housing, the bottom housing comprising a back plate and a side plate adjacent to each other, the side plate being adjacent to the frame and having an opening near the back plate, the circuit board being disposed on the back plate and including a protruding end extending through the opening, and the light source being disposed on the protruding end; wherein, in a direction passing through the plane of the display panel, the height of the opening is equal to the height of the side plate; and the back plate having a reinforcing portion protruding from the back plate and near the opening.

16. A vehicle detection system comprising a display device as described in any one of claims 1 to 15 and a camera, the vehicle detection system being disposed in a vehicle, and the camera being disposed on the side of the display panel facing the backlight module.
