Abstract

Embodiments of the present invention relate to an onboard display system for solving the problem of display image with poor clarity in the prior art, achieving a better grasp to situation outside the vehicle and driving safety of the driver. The onboard display system includes a camera module and a display. The camera module is installed at a predetermined position outside the vehicle for taking traffic images during driving and sending them to the display. The display is arranged inside the vehicle and adhered to the front windshield of the vehicle or hang before the front windshield of the vehicle for displaying the traffic images it received.

Claims

1. An onboard display system comprising a camera module and a display, wherein

the camera module is installed at a predetermined position outside a vehicle for taking traffic images during driving and sending the traffic images to the display;

and

the display is arranged inside the vehicle and adhered to or hung from a front windshield of the vehicle, which is opaque, for displaying the traffic images received from the camera module during driving, so that a driver looking toward the front windshield will only see the traffic images on the display and not through the windshield;

wherein the display is of the same size as that of the front windshield of the vehicle.

2. The onboard display system according to claim 1, wherein the camera module comprises a plurality of cameras, which are installed outside of the front windshield of the vehicle, and/or installed outside of a rear windshield of the vehicle.

3. The onboard display system according to claim 2, wherein the cameras comprise infrared cameras.

4. The onboard display system according to claim 1, wherein the display is an organic light emitting display or a LCD.

5. The onboard display system according to claim 4, wherein the-display is the organic light emitting display provided with a touch structure, or the display is the LCD provided with a touch structure.

6. The onboard display system according to claim 1, further comprising a projection system which is arranged on a central console of the vehicle or on an inside of a roof of the vehicle, wherein

the camera module further serves to send the traffic images to the projection system;

and

the projection system serves to project the received traffic images onto an entirety of the front windshield of the vehicle.

7. The onboard display system according to claim 6, wherein the projection system comprises a plurality of mini projectors.

8. The onboard display system according to claim 6, further comprising an image processing module which serves to receive the traffic images sent from the camera module, to process the received traffic images and to send the processed traffic images to the display or the projection system.

9. The onboard display system according to claim 8, wherein the image processing module serves to perform distortion correction, brightness adjustment and contrast adjustment to the received traffic images.
