Abstract

The present invention discloses a display device and a manufacturing method therefor. The display device includes: a display screen, and a transparent cover plate provided above the display screen. The transparent cover plate includes an upper surface and two opposite side surfaces. The upper surface is connected with the two side surfaces to form a chamfer edge via chamfers respectively. The width of the transparent cover plate is not greater than that of the display screen.

First claim

What is claimed is:

1 . A display device, comprising: a display screen, and a transparent cover plate provided above the display screen, wherein p 1 the transparent cover plate comprises an upper surface and two opposite side surfaces, and the upper surface is connected with the two side surfaces respectively to form a chamfer edge via chamfers; and
the width of the transparent cover plate is not greater than that of the display screen.

2 . The display device according to claim 1 , wherein the display screen comprises a liquid crystal panel;
the transparent cover plate is provided above the liquid crystal panel; and the liquid crystal panel comprises a display area, the width of the display area being greater than or equal to that of the upper surface of the transparent cover plate.

3 . The display device according to claim 2 , wherein the width of the display area is equal to that of the transparent cover plate.

4 . The display device according to claim 2 , wherein the display screen further comprises a touch panel provided above the liquid crystal panel; and
the width of the liquid crystal panel is equal to that of the touch panel.

5 . The display device according to claim 1 , further comprising: a middle frame, wherein
the middle frame comprises a main plate and a side plate which are formed integrally, the main plate and the side plate being perpendicular to each other to form an accommodating space; and the transparent cover plate is entirely or partially placed in the accommodating space.

6 . The display device according to claim 5 , wherein the height of the transparent cover plate is greater than that of the side plate.

7 . The display device according to claim 5 , wherein the chamfer edge comprises a circular arc segment and a straight line segment; and
the straight line segment of the transparent cover plate abuts against the side plate, and the circular arc segment is higher than the side plate.

8 . The display device according to claim 5 , wherein the side plate comprises a beveled edge, a tangent line of at least one point on the chamfer edge of the transparent cover plate passing through the beveled edge of the side plate.

9 . The display device according to claim 5 , further comprising: a backlight module, wherein
a shading plate is provided between the liquid crystal panel and the backlight module, the shading plate covering a periphery of the backlight module; and the width of the shading plate is greater than or equal to a gap between the display area and the side plate, and the shading plate shades the gap.

10 . The display device according to claim 9 , wherein a flange for carrying the display screen is provided on the inner side of the side plate; and
the shading plate is provided between the flange and the display screen, and abuts against the side plate.

11 . The display device according to claim 1 , wherein the transparent cover plate is made of glass or plastic.

12 . The display device according to claim 1 , wherein the chamfer edge is any one or a combination of: a folded line edge, an oblique edge, and a circular arc.

13 . A display device, comprising: a liquid crystal panel, and a transparent cover plate provided above the liquid crystal panel, wherein
the transparent cover plate comprises an upper surface and two opposite side surfaces, and the upper surface is connected with the two side surfaces respectively to form a chamfer edge via chamfers; and perpendicular light emitted from the liquid crystal panel partially reaches the chamfer edge of the transparent cover plate.

14 . The display device according to claim 13 , wherein the transparent cover plate further comprises a lower surface, the lower surface comprises two side edges connected with the side surfaces, and the perpendicular light emitted from the liquid crystal panel partially reaches the two side edges of the lower surface.

15 . The display device according to claim 13 , further comprising a touch panel provided above the liquid crystal panel, wherein
the width of the liquid crystal panel is equal to that of the touch panel.

16 . The display device according to claim 13 , further comprising: a backlight module, wherein
a shading plate is provided between the liquid crystal panel and the backlight module, the shading plate covering a periphery of the backlight module.

17 . A manufacturing method for a display device, comprising:
providing a display screen and a transparent cover plate, the transparent cover plate comprising an upper surface and two opposite side surfaces; providing the transparent cover plate above the display screen, and setting the width of the transparent cover plate to be not greater than that of the display screen; and connecting the upper surface of the transparent cover plate with the two side surfaces respectively to form a chamfer edge via chamfers, to make perpendicular light emitted from the display screen partially reach the chamfer edge of the transparent cover plate.

18 . The method according to claim 17 , wherein the display screen comprises a liquid crystal panel;
the transparent cover plate is provided above the liquid crystal panel; and the liquid crystal panel comprises a display area, the width of the display area being greater than or equal to that of the upper surface of the transparent cover plate.

19 . The method according to claim 18 , wherein the width of the display area is equal to that of the transparent cover plate.

20 . The method according to claim 18 , wherein the display screen further comprises a touch panel provided above the liquid crystal panel; and
the width of the liquid crystal panel is equal to that of the touch panel.
