Display device and transportation vehicle display system

Abstract

This invention provides a display device and a vehicle display system including the same. The display device includes a display panel, a backlight module, a first fogging layer, and an optical sensor. The backlight module is disposed on one side of the display panel and includes: a light source module configured to emit light having a first wavelength range; and a diffusion layer disposed between the light source module and the display panel and having an opening. The first fogging layer is disposed between the display panel and the backlight module. The optical sensor is disposed on the side of the first fogging layer away from the display panel and corresponding to the opening, and is configured to receive light having a second wavelength range through the opening and the first fogging layer. The fogging of the first fogging layer for the first wavelength range is greater than the fogging for the second wavelength range.

Claims

1. A display device, comprising: A display panel includes a plurality of display units; a backlight module is disposed on one side of the display panel and includes: a light source module configured to emit light having a first wavelength range; and a diffusion layer disposed between the light source module and the display panel and having an opening; a first fogging layer disposed between the display panel and the backlight module; and an optical sensor disposed on the side of the first fogging layer away from the display panel and corresponding to the opening, and the optical sensor is configured to receive light having a second wavelength range through the opening and the first fogging layer; wherein the fog level of the first fogging layer for the first wavelength range is greater than the fog level for the second wavelength range.

2. The display device as claimed in claim 1, wherein the first wavelength range includes visible light and the second wavelength range includes infrared light.

3. The display device as claimed in claim 1, wherein the haze of the first atomizing layer is greater than or equal to 30% for the first wavelength range.

4. The display device as claimed in claim 1, wherein the haze of the first atomizing layer for the second wavelength range is less than or equal to 50%.

5. The display device as claimed in claim 1, wherein the distance between the diffusion layer and the first atomizing layer in the stacking direction of the backlight module and the display panel is greater than or equal to 5 mm.

6. The display device as claimed in claim 1 further includes a spacer disposed between the diffusion layer and the first atomizing layer and having light transmittance.

7. The display device as claimed in claim 6, wherein the thickness of the spacer in the stacking direction of the backlight module and the display panel is greater than or equal to 5 mm.

8. The display device as claimed in claim 1, further comprising a spacer post, wherein the opening penetrates the diffusion layer, the spacer post being at least partially disposed in the opening of the diffusion layer and having light transmittance.

9. The display device as claimed in claim 8, wherein the spacer post has a side side disposed facing the diffusion layer to form the inner surface of the opening and at least partially forming a rough surface.

10. The display device as claimed in claim 8, wherein the spacer has a bottom surface disposed toward the optical sensor and at least partially forms a rough surface.

11. The display device as claimed in claim 8, wherein the spacer further includes a light-blocking portion disposed on one side of the spacer facing the optical sensor and having a predetermined pattern.

12. The display device as claimed in claim 8, wherein the spacer includes a body and a flange, the body being disposed in the opening of the diffusion layer, and the flange being disposed on the side of the body facing the optical sensor and at least partially fixed to the diffusion layer.

13. The display device as claimed in claim 8 further includes a second atomizing layer disposed on the side of the spacer post facing the optical sensor, and a gap is formed between the second atomizing layer and the diffusion layer.

14. The display device as claimed in claim 1, wherein the light source module includes a substrate and a plurality of light-emitting units disposed on one side of the substrate facing the diffusion layer, the substrate having a through hole corresponding to the opening of the diffusion layer, and the optical sensor being at least partially disposed on the side of the substrate away from the diffusion layer and configured to capture an image through the through hole.

15. A vehicle display system comprising a display device as described in any one of claims 1 to 14 and disposed on a control console of a vehicle, the optical sensor including a camera configured to capture images of the interior of the vehicle.
