Abstract

The present invention discloses a display system, comprising at least one jointed screen which is composed of a plurality of liquid crystal display panels jointed with each other, in which, each liquid crystal display panel is provided with a first polarizer only at a light entering side thereof, so that a visible angle at which contents displayed by the liquid crystal display panel can be seen from a light exiting side thereof is an obtuse angle; two adjacent jointed liquid crystal display panels are jointed with each other at their adjacent sides, and a joint angle formed at the light exiting side is greater than a right angle, such that the light exiting side of each display panel is located in a region covered by an angle range of the visible angle of at least one display panels other than said display panel.

First claim

What is claimed is:

1. A display system, comprising at least one jointed screen which is composed of a plurality of liquid crystal display panels jointed with each other, in which:
each liquid crystal display panel is provided with a first polarizer only at a light entering side thereof, so that a visible angle at which contents displayed by the liquid crystal display panel can be seen from a light exiting side of the liquid crystal display panel is an obtuse angle;
two adjacent jointed liquid crystal display panels are jointed with each other at their adjacent sides, and a joint angle formed at the light exiting side is greater than a right angle, such that the light exiting side of each liquid crystal display panel is located in a region covered by an angle range of the visible angle of at least one liquid crystal display panels other than said liquid crystal display panel.

2. The display system according to claim 1 , wherein the angle range of the visible angle at which contents displayed by the liquid crystal display panel can be seen from the light exiting side of the liquid crystal display panel increases as the size of the liquid crystal display panel is increased.

3. The display system according to claim 1 , wherein the visible angle at which contents displayed by the liquid crystal display panel can be seen from the light exiting side of the liquid crystal display panel is in an angle range of 120 degrees to 180 degrees.

4. The display system according to claim 3 , wherein the visible angle at which contents displayed by the liquid crystal display panel can be seen from the light exiting side of the liquid crystal display panel is in an angle range of 150 degrees to 180 degrees.

5. The display system according to claim 1 , wherein in the at least one jointed screen, the plurality of liquid crystal display panels jointed with each other are arranged in such manner that the joint angles between them at the light exiting side are alternatively arranged as obtuse angles and reflex angles, so as to form the jointed screen in the shape of a polygonal line.

6. The display system according to claim 5 , wherein the at least one jointed screen comprises two jointed screens, and the light exiting sides of respective liquid crystal display panels in the two jointed screens all face a space between the two jointed screens.

7. The display system according to claim 6 , wherein the two jointed screens are arranged in mirror symmetry, or the two jointed screens are arranged in such manner that a spacing between them is uniform.

8. The display system according to claim 7 , wherein the angle range of the visible angle at which contents displayed by the liquid crystal display panel can be seen from the light exiting side of the liquid crystal display panel increases as the size of the liquid crystal display panel is increased.

9. The display system according to claim 7 , wherein the visible angle at which contents displayed by the liquid crystal display panel can be seen from the light exiting side of the liquid crystal display panel is in an angle range of 120 degrees to 180 degrees.

10. The display system according to claim 9 , wherein the visible angle at which contents displayed by the liquid crystal display panel can be seen from the light exiting side of the liquid crystal display panel is in an angle range of 150 degrees to 180 degrees.

11. The display system according to claim 1 , wherein the joint angles of the plurality of liquid crystal display panels jointed with each other all are obtuse angles, so that the jointed screen forms a ring structure, and the light exiting sides of the respective liquid crystal display panels face a region defined by the ring structure.

12. The display system according to claim 11 , wherein the liquid crystal display panel is made of a flexible screen or a hard screen.

13. The display system according to claim 11 , wherein the angle range of the visible angle at which contents displayed by the liquid crystal display panel can be seen from the light exiting side of the liquid crystal display panel increases as the size of the liquid crystal display panel is increased.

14. The display system according to claim 11 , wherein the visible angle at which contents displayed by the liquid crystal display panel can be seen from the light exiting side of the liquid crystal display panel is in an angle range of 120 degrees to 180 degrees.

15. The display system according to claim 14 , wherein the visible angle at which contents displayed by the liquid crystal display panel can be seen from the light exiting side of the liquid crystal display panel is in an angle range of 150 degrees to 180 degrees.
