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

1 .- 20 . (canceled)

21 . A display device comprising:
a display panel having flexibility; and a driving portion being capable of changing the display panel between a first form and a second form reversibly, wherein the display panel can be installed inside a moving object, wherein the first form is a form in which the display panel is suspended, and wherein the second form is a form in which the display panel is stored upward.

22 . The display device according to claim 21 ,
wherein the display panel is stored so as to be folded in the second form.

23 . The display device according to claim 21 ,
wherein the display panel is stored so as to be wound in the second form.

24 . A vehicle comprising:
the display device according to claim 21 , wherein the display device is attached to an upper portion of a car body interior.

25 . The vehicle according to claim 24 , comprising:
a sun visor attached to a ceiling of a car body, wherein the display device is attached to a position to be covered when the sun visor is flipped up and when the display panel is in the second form.

26 . The vehicle according to claim 24 , comprising:
a sun visor attached to a ceiling of a car body, wherein the display device is attached to the sun visor.

27 . A display device comprising:
a display panel having flexibility; and a driving portion being capable of changing the display panel between a first form and a second form reversibly, wherein the display panel can be installed in an upper portion of a car body in front of a driver's seat, wherein the first form is a form in which the display panel is suspended and a display surface of the display panel is located in a visible range of a driver, and wherein the second form is a form in which the display panel is stored upward.

28 . The display device according to claim 27 ,
wherein the display panel is stored so as to be folded in the second form.

29 . The display device according to claim 27 ,
wherein the display panel is stored so as to be wound in the second form.

30 . A vehicle comprising:
the display device according to claim 27 , wherein the display device is attached to an upper portion of a car body interior.

31 . The vehicle according to claim 30 , comprising:
a sun visor attached to a ceiling of a car body, wherein the display device is attached to a position to be covered when the sun visor is flipped up and when the display panel is in the second form.

32 . The vehicle according to claim 30 , comprising:
a sun visor attached to a ceiling of a car body, wherein the display device is attached to the sun visor.

33 . A driving support system comprising:
a control portion; a detection portion; a first imaging portion; and a display device comprising a display panel having flexibility and a driving portion, wherein the detection portion is capable of detecting a condition of a transmission in a car body and outputting a detection information to the control portion, wherein the first imaging portion is capable of taking a picture of an area behind the car body, wherein the display device can be installed in an upper portion of the car body in front of a driver's seat, wherein the driving portion is capable of changing the display panel between a first form and a second form reversibly, wherein the first form is a form in which the display panel is suspended and a display surface of the display panel is located in a visible range of a driver, wherein the second form is a form in which the display panel is stored upward, wherein the control portion is capable of switching to a first state or a second state in accordance with the detection information, wherein the first state is a state in which the display panel is in the first form and a first picture taken by the first imaging portion is displayed on the display surface of the display panel, and wherein, in the second state, display on the display surface of the display panel is stopped and the display panel is in the second form.

34 . The driving support system according to claim 33 ,
wherein the display panel is stored so as to be folded in the second form.

35 . The driving support system according to claim 33 ,
wherein the display panel is stored so as to be wound in the second form.

36 . The driving support system according to claim 33 ,
wherein the control portion is capable of switching to the first state when the condition of the transmission is a reverse position, and wherein the first form is a form in which a lower edge of the display panel is located at a level equal to or lower than a level of an eye point of the driver.

37 . The driving support system according to claim 33 ,
wherein the control portion is capable of detecting positional information about an object from the first picture, wherein the control portion is capable of determining a direction in which the car body should be moved from the positional information, and wherein the control portion is capable of displaying an image indicating a direction in which a steering wheel should be operated together with the first picture on the display surface in the first state.

38 . The driving support system according to claim 33 ,
wherein the control portion is capable of switching to a third state when the condition of the transmission is a forward position, wherein the third state is a state in which the display panel is in a third form and the first picture is displayed on the display surface, and wherein the third form is a form in which a lower edge of the display panel is located at a level higher than a level of an eye point of the driver.

39 . The driving support system according to claim 33 , comprising:
a second imaging portion, wherein the second imaging portion is capable of taking a picture of an area in front of or at a side of the car body, and wherein the control portion is capable of displaying a second picture taken by the second imaging portion on the display surface of the display panel in the first state.

40 . The driving support system according to claim 33 ,
wherein the control portion is capable of displaying a horizontally flipped picture of the first picture on the display surface of the display panel in the first state.

41 . A vehicle comprising the driving support system according to claim 33 ,
wherein the display device is attached to an upper portion of the car body interior.

42 . The vehicle according to claim 41 , comprising:
