Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
Shown in Fig. 1-8, a kind of seamless splicing display device, comprise two or more than two display screen 2, every two adjacent display screens 2 all splice fixing, two display screen 2 stitching portions form piece, the top of piece is provided with optic panel 1, optic panel 1 has upper surface and lower surface, the both sides of optic panel 1 are dip plane, dip plane is symmetrical, the upper surface of optic panel 1 is parallel with lower surface, and the lower surface of optic panel 1 overlaps with the display surface of display screen 2, and optic panel 1 and display screen 2 are coaxially arranged; The upper surface of optic panel 1 is the plane of symmetry or the plane with V-type groove; V-type groove is single group or many groups or Fresnel surface; The lower surface of optic panel 1 is the face of amplifying face with Central Symmetry arc; All located by mechanical pilot hole or mechanical locating slot between optic panel 1 and optic panel 1, between optic panel 1 and display screen 2, and be connected and fixed by optical glue or optical adhesive tape; Display screen 2 is LCD tiled display equipment or PDP tiled display equipment or DLP rear-projection tiled display equipment or LED rear-projection tiled display equipment or projector's tiled display equipment; The material of optic panel 1 is transmissive optical glass or plastic cement; The lower surface of optic panel 1 and the display surface intersection of display screen 2 are frosting.
The first embodiment of the present utility model: optic panel 1 as shown in Figure 1, optic panel 1 is symmetrical structure, there is upper and lower surface, and monosymmetric dip plane, wherein upper surface is the plane of symmetry with V-type groove, lower surface is the face of amplifying face with Central Symmetry arc, overlap with effective display surface of display screen 2, upper and lower surface is parallel, optic panel 1 is positioned at the top of the piece of display screen 2, the screen being parallel to display screen 2 is also vertical with the piece between display screen 2, and the axis of symmetry of optic panel 1 is positioned at the centre of the piece of display screen 2.
The second embodiment of the present utility model: optic panel 1 as shown in Figure 2, two pieces of optic panel 1 full symmetrics, and by optical adhesive tape or glue bonding, one piece of synthesizing optical panel 1 is formed after bonding, synthesizing optical panel 1 finally has upper and lower surface, and monosymmetric dip plane, wherein upper surface is the plane of symmetry with V-type groove, lower surface is the face of amplifying face with Central Symmetry arc, overlap with effective display surface of display screen 2, upper and lower surface is parallel, described optic panel 1 is positioned at the top of the piece of display screen 2, the screen being parallel to display screen 2 is also vertical with the piece between display screen 2, the axis of symmetry of optic panel 1 is positioned at the centre of the piece of display screen 2.
The principle reversible according to light path, when human eye watches display screen 2 from different perspectives, light enters optic panel 1 through the surface refraction of upper surface V-type groove, the light entering optic panel 1 again reflects through the arc amplification face of lower surface or is totally reflected, and finally drop in effective indication range of display screen 2, thus effectively avoid light and fall into splicing gap place between the frame of display screen 2 or display screen 2.That is, human eye can't see the splicing gap between the frame of display screen 2 or display screen 2, there is not missing image, discontinuous situation.
