Abstract

A display device or a driving support system which enables a driver to obtain information easily is provided. A display device or a driving support system which is unlikely to impose a burden on a driver is provided. A display device or a driving support system which is suitable for space saving is provided. A display device or a driving support system which is capable of large-area display is provided. A display device or a driving support system which does not impair the aesthetic appearance of the car interior is provided. The display device includes a display panel which has flexibility and can be transformed between a first form and a second form, and a driving means having a function of reversibly changing the display panel between the first form and the second form. The first form is a form in which a display surface of the display panel is suspended, and the second form is a form in which the display panel is stored upward.

First claim

The invention claimed is:

1. A driving support system comprising:
a display device comprising:
a display panel having flexibility; and
a winding mechanism; and

an imaging device configured to take a picture of surroundings of a vehicle,
wherein the display panel is configured to be changed between a first form in which the display panel is suspended and displays the picture taken by the imaging device and a second form in which the display panel is stored inside the vehicle by the winding mechanism,
wherein in the first form, a display surface of the display panel is flat, and
wherein in the second form, the display panel is folded so that a first region of the display surface is bent inward and a second region of the display surface is bent outward.

2. The driving support system according to claim 1 , wherein in the first form, the display panel is in a visible range of a driver.

3. The driving support system according to claim 1 , wherein in the first form, a lower edge of the display panel is at a level equal to or lower than a level of an eye point of a driver.

4. The driving support system according to claim 1 , wherein in the second form, the display panel is stored inside a ceiling of the vehicle.

5. The driving support system according to claim 1 , wherein the surroundings of the vehicle include an area behind the vehicle.

6. The driving support system according to claim 1 , wherein the surroundings of the vehicle include an area at a side of the vehicle.

7. A driving support system comprising:
a display device comprising:
a display panel having flexibility;
a fixing portion configured to fix an upper end of the display panel;
a winding mechanism; and
a cord attached to the winding mechanism; and

an imaging device configured to take a picture of surroundings of a vehicle,
wherein the display panel is configured to be changed between a first form in which the display panel is suspended and displays the picture taken by the imaging device and a second form in which the display panel is stored inside the vehicle by winding the cord by the winding mechanism,
wherein in the first form, a display surface of the display panel is flat, and
wherein in the second form, the display panel is folded so that a first region of the display surface is bent inward and a second region of the display surface is bent outward.

8. The driving support system according to claim 7 , wherein the winding mechanism includes a circuit for supplying a signal or a voltage to the display panel.

9. The driving support system according to claim 7 , wherein in the first form, the display panel is in a visible range of a driver.

10. The driving support system according to claim 7 , wherein in the first form, a lower edge of the display panel is at a level equal to or lower than a level of an eye point of a driver.

11. The driving support system according to claim 7 , wherein in the second form, the display panel is stored inside a ceiling of the vehicle.

12. The driving support system according to claim 7 , wherein the surroundings of the vehicle include an area behind the vehicle.

13. The driving support system according to claim 7 , wherein the surroundings of the vehicle include an area at a side of the vehicle.
