Abstract

Provided is a display room mirror system, including a display module that outputs images captured by a first camera and a second camera, so that the driver can secure his or her field of vision for the side rear as well as the rear of a vehicle using only one room mirror disposed in an inner part of the vehicle without confirming the side mirror, thereby effectively reducing moving lines in the driver'"'"'s field of vision.

Claims

1. A display room mirror system, comprising:

a camera module configured to capture external images of a vehicle;

a display module configured to output images inputted from the camera module; and

a room mirror in which the display module is received.

2. The display room mirror system of claim 1, wherein the camera module comprises a first camera and a second camera configured to capture left and right rear view images of the vehicle.

3. The display room mirror system of claim 2, wherein the first camera and the second camera are mounted to left and right side mirrors of the vehicle, respectively.

4. The display room mirror system of claim 3, wherein the camera module further comprises a camera control unit adjusting capturing directions of the first camera and the second camera.

5. The display room mirror system of claim 4, wherein the camera control unit changes the capturing directions of the first camera and the second camera depending on a variation in steering angle of a handle for the vehicle.

6. The display room mirror system of claim 2, wherein the display module is disposed on a rear surface of the room mirror, and individually outputs images inputted from the first camera and the second camera.

7. The display room mirror system of claim 2, wherein the display module is disposed at ends of left and right sides of the room mirror, respectively, and individually outputs images obtained from the first camera and the second camera.

8. The display room mirror system of claim 2, wherein the display module is disposed on the rear surface of the room mirror and dividedly outputs the images obtained from the first camera and the second camera.

9. The display room mirror system of claim 8, further comprising:

an image conversion button that selectively outputs only one image among the images obtained from the first camera and the second camera or dividedly outputs the images at the same time.

10. The display room mirror system of claim 2, further comprising:

a power button unit that turns on or off a power source of the display module.

11. The display room mirror system of claim 10, wherein the power button unit is disposed at one side of the room mirror.

12. The display room mirror system of claim 10, wherein the power button unit is composed of a first button and a second button that individually turn on or off the power source of the display module.

13. The display room mirror system of claim 1, wherein the room mirror comprises a half mirror.

14. The display room mirror system of claim 2, wherein the room mirror comprises an electrochromic mirror.

15. The display room mirror system of claim 14, wherein the electrochromic mirror comprises:

a first substrate and a second substrate facing each other;

an electrode and a reflective layer formed on facing surfaces of the first substrate and the second substrate; and

an electrochromic material layer disposed between the electrode and the reflective layer.

16. The display room mirror system of claim 15, wherein at least one of the first substrate and the second substrate is a transparent substrate.

17. The display room mirror system of claim 16, wherein the electrode is a transparent electrode.

18. The display room mirror system of claim 17, wherein the electrochromic material layer contains an electrochromic material and an electrolyte.

19. The display room mirror system of claim 17, wherein the electrochromic material layer is formed by mixing a liquid electrochromic material and a liquid electrolyte.

20. The display room mirror system of claim 18, wherein the electrochromic material layer comprises a solid electrochromic material and an electrolyte layer.
