Embodiment Construction

[0038] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0039] An embodiment of the present invention provides a splicing screen, such as Figure 2-1 as shown, Figure 2-1 It is a schematic structural diagram of a splicing screen provided by an embodiment of the present invention, and the splicing screen may include:

[0040] The light-shielding film 10 and a plurality of screens 22 arranged in an array are used to prevent the light emitted from the side of the screen 22 .

[0041] At adjacent edges of every two adjacent screens 22 , a curved surface 221 is provided on a side close to the light-emitting surface A. As shown in FIG. In practical applications, no arc surface 221 is provided at the non-adjacent edges of every two adjacent screens 22 , that is, no arc surface 221 is provided a...

Abstract

The invention discloses a splicing screen and a back projection unit, and belongs to the technical field of display. The splicing screen comprises a shading film and a plurality of screens arranged in an array, wherein the shading film is used for preventing light rays from being emitted on the side faces of the screens; and at the positions of adjacent edges of every two adjacent screens, a cambered surface is arranged on the side close to an emitted surface. The cambered surface is arranged on the side close to the emergent surface at the positions of adjacent edges of every two adjacent screens, so that the light rays are emitted at the positions of spicing gaps, the discontinuity, appearing in a display image, of the splicing screen is avoided, and then the display effect of the splicing screen is better. The invention is used for the splicing screen with the back projection unit.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a splicing screen and a rear projection unit. Background technique [0002] Projection splicing display, also known as splicing screen, is to splice multi-screen images together to realize ultra-large screen and ultra-high-resolution image display. [0003] Please refer to figure 1 , figure 1 It is a structural schematic diagram of a splicing screen provided in the prior art. The splicing screen is composed of multiple rear projection units 11 closely spliced ​​together, and there is a splicing gap 12 between two adjacent rear projection units 11 . Wherein, each rear projection unit 11 may include a projector 111, a screen 112 and a fixed bracket 113, the screen 112 may be a Fresnel optical screen, and the Fresnel optical screen may include: a Fresnel lens layer 112b and a lenticular lens Layer 112a. In each rear projection unit 11, the light emitted by the projector 111 exi...
