Abstract

This disclosure relates to a display device, a display method and a method of manufacturing the display device. The display device includes: a first display screen and a second display screen, wherein a plane where the first display screen is in and a plane where the second display screen is in form an angle in a range of 0-180 degrees; and an optical control structure disposed on a light emission side of the first display screen, for controlling a range of an angle of view of the first display screen.

First claim

What is claimed is:

1 . A display device, comprising:
a first display screen and a second display screen, wherein a plane where the first display screen is in and a plane where the second display screen is in form an angle in a range of 0-180 degrees; and an optical control structure disposed on a light emission side of the first display screen, for controlling a range of an angle of view of the first display screen.

2 . The display device according to claim 1 , wherein the display device comprises a foldable display screen having a first display area and a second display area, which are formed by the first display screen and the second display screen respectively.

3 . The display device according to claim 2 , wherein the first display screen and the second display screen are connected via a shaft and rotatable about the shaft.

4 . The display device according to claim 2 , wherein the foldable display screen is an flexible display screen, which has a flexure zone, with the first display area and the second display area on opposites sides and disposed integrally with the first display area and the second display area.

5 . The display device according to claim 2 , wherein the light emission side of the first display screen is in the same direction as that of the second display screen in a case where the angle formed by the plane where the first display area is in and the plane where the second display area is in is 180 degree.

6 . The display device according to claim 1 , wherein the first display screen and the second display screen are juxtaposed one above the other, and wherein the second display screen is a transparent display screen.

7 . The display device according to claim 6 , wherein the optical control structure is located between the first display screen and the second display screen, and the light emission side of the first display screen is in the same direction as a light emission side of the second display screen.

8 . The display device according to claim 7 , wherein the first display screen comprises a plurality of first pixels separated by pixel-defined layer, the second display screen comprises a plurality of second pixels separated by a transparent zone, a position of the plurality of first pixels corresponds to that of the transparent zone, and a position of the plurality of second pixels corresponds to that of the pixel-defined layer.

9 . The display device according to claim 8 , wherein the optical control structure comprises:
a plurality of columns separated by a light transmitting material layer, wherein a material of each column comprises a light absorption material, a position of the plurality of columns corresponds to that of the pixel-defined layer, and a position of the light transmitting material layer corresponds to that of the plurality of first pixels.

10 . The display device according to claim 9 , further comprising: a touch panel disposed on the light emission side of the second display screen.

11 . The display device according to claim 6 , wherein the optical control structure is formed integrally with the first display screen or the second display screen.

12 . The display device according to claim 1 , further comprising: a touch panel configured to operate with at least one of the first display screen or the second display screen.

13 . The display device according to claim 1 , further comprising:
a first control circuit configured to control on or off of the first display screen; and a second control circuit configured to control on or off of the second display screen.

14 . A display method of a display device, the display device comprising a first display screen and a second display screen, and an optical control structure disposed on a light emission side of the first display screen, for controlling a range of an angle of view of the first display screen, the display method comprising:
in a first display mode, turning on the first display screen and turning off the second display screen; and in a second display mode, turning on the second display screen and turning off the first display screen.

15 . The display method according to claim 14 , further comprising: in a third display mode, turning on the first display screen and the second display screen.

16 . The display method according to claim 14 , wherein the display device comprises a foldable display screen having a first display area and a second display area, in which the first display screen and the second display screen are located respectively, and the display method further comprises:
folding the foldable display screen, such that a plane where the first display screen is in and a plane where the second display screen is in form a specified angle.

17 . An on-board display device comprising: the display device according to claim 1 .

18 . The on-board display device according to claim 17 , wherein the display device is disposed on a central console position or a co-pilot position.

19 . The on-board display device according to claim 17 , wherein the display device comprises a foldable display screen, of which the first display screen and the second display screen are located in different areas, the light emission side of the first display screen faces inside a vehicle, and a light emission side of the second display screen faces outside the vehicle.
