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 vehicle having a driving support system, the driving support system comprising:
a control portion;
a detection portion;
a first imaging portion; and
a display device comprising a flexible display panel,
wherein the detection portion is configured to detect a condition of the vehicle and output information to the control portion,
wherein the first imaging portion is configured to take a first picture of a first area surrounding the vehicle,
wherein the control portion is configured to change a form of the flexible display panel between a first form and a second form reversibly, according to the information,
wherein in the first form, the flexible display panel is spread from a portion of an interior of the vehicle, and
wherein in the second form, the flexible display panel is stored in the portion of the interior of the vehicle.

2. The vehicle according to claim 1 , wherein, in the second form, the flexible display panel is folded and stored in the portion of the interior of the vehicle.

3. The vehicle according to claim 1 , wherein, in the second form, the flexible display panel is wound and stored in the portion of the interior of the vehicle.

4. The vehicle according to claim 1 , wherein in the first form, a lower edge of the flexible display panel is located at a level equal to or lower than a level of an eye point of a driver.

5. The vehicle according to claim 1 , wherein the control portion is capable of switching to the first form when the condition of a transmission of the vehicle is a reverse position.

6. The vehicle according to claim 1 , further comprising:
a second imaging portion configured to take a second picture of a second area surrounding the vehicle,
wherein the flexible display panel is capable of displaying the first picture or the second picture.

7. A vehicle according to claim 1 , wherein the flexible display panel is attached to an upper portion of the interior of the vehicle.

8. The vehicle according to claim 1 ,
wherein a sun visor is attached to a ceiling of the interior of the vehicle, and
wherein the display device is attached to the sun visor.

9. A vehicle having a driving support system, the driving support system comprising:
a control portion;
a detection portion;
a first imaging portion; and
a display device comprising a flexible display panel,
wherein the detection portion is configured to detect a condition of a transmission of the vehicle and output information to the control portion,
wherein the first imaging portion is configured to take a first picture of a first area surrounding the vehicle,
wherein the control portion is configured to change a form of the flexible display panel between a first form and a second form reversibly, according to the information,
wherein, in the first form, the flexible display panel is configured to be spread and display the first picture, and
wherein, in the second form, the flexible display panel is stored in a portion of an interior of the vehicle and display on the display portion of the flexible display panel is stopped.

10. The vehicle according to claim 9 , wherein, in the second form, the flexible display panel is folded and stored in the portion of the interior of the vehicle.

11. The vehicle according to claim 9 , wherein, in the second form, the flexible display panel is wound and stored in the portion of the interior of the vehicle.

12. The vehicle according to claim 9 , wherein in the first form, a lower edge of the flexible display panel is located at a level equal to or lower than a level of an eye point of a driver.

13. The vehicle according to claim 9 , wherein the control portion is capable of switching to the first form when the condition of the transmission of the vehicle is a reverse position.

14. The vehicle according to claim 9 , further comprising:
a second imaging portion configured to take a second picture of a second area surrounding the vehicle,
wherein the display portion is capable of displaying the first picture or the second picture.

15. A vehicle according to claim 9 , wherein the flexible display panel is attached to an upper portion of the interior of the vehicle.

16. The vehicle according to claim 9 ,
wherein a sun visor is attached to a ceiling of the interior of the vehicle, and
wherein the display device is attached to the sun visor.
