Embodiment Construction

[0028] The following descriptions of the various embodiments refer to the accompanying drawings to illustrate specific embodiments that the present application can be used to implement. The directional terms mentioned in this application, such as [top], [bottom], [front], [back], [left], [right], [inside], [outside], [side], etc., are for reference only The orientation of the attached schema. Therefore, the directional terms used are used to illustrate and understand the application, but not to limit the application. In the figures, structurally similar elements are denoted by the same reference numerals.

[0029] The present application aims at the technical problem that the splicing seam cannot be eliminated in the splicing screen of the prior art, especially the splicing seam will be enlarged under a large viewing angle. This embodiment can solve this defect.

Abstract

The invention provides a spliced screen. The spliced screen comprises at least two display panels, cover boards and optical thin films, wherein a non-display area on the peripheral edge of each display panel comprises a frame, and a gap is formed at the spliced position of each two adjacent display panels; the cover boards are arranged on the surfaces of the display panels, the surfaces of the sides, far away from the display panels, of the cover boards are planes, and the surfaces of the sides, close to the display panels, of the cover boards comprise bent areas and plane areas; the bent areas correspond to the frame areas of the display panels, and the plane areas correspond to display areas of the display panels; the optical thin films are arranged on the surfaces of the cover boards, and comprise upper surfaces far away from one sides of the cover boards and lower surfaces close to one sides of the cover boards; and the lower surfaces of the optical thin films comprise microstructural areas corresponding to the frame areas, and the upper surfaces of the optical thin films comprise scattering areas corresponding to the frame areas.

Description

technical field [0001] The present application relates to the field of display panel manufacturing, in particular to a splicing screen. Background technique [0002] Liquid crystal display is the mainstream display device today, and it is widely used in the splicing field of larger screens. However, due to the structural principle of the liquid crystal display, there will be a black frame around each display, which mainly includes the frame glue for sealing the liquid crystal, the circuit for inputting data signals or scanning signals, and the thickness of the structural frame. [0003] During the splicing process of large screens, the phenomenon of black borders between different LCD screens, that is, the so-called splicing seams, will have a greater impact on viewing. Generally, visual seam elimination is achieved by adding an optical glass cover plate with optical characteristics at the seam. However, using this method of optical vision to eliminate stitching, there wil...
