Embodiment 1
Refering to Fig. 1~3, the spliced display device of the present embodiment includes multiple display devices 10 and transparent optical layer
20, all display devices 10 are adjacent to two-by-two to be stitched together, also, covered with one on the exiting surface of each display device 10
Layer optical layer 20.Display device 10 includes the viewing area at middle part and the non-display area of viewing area periphery, non-display area
Periphery be black matrix region (BM areas), the edge of the surrounding of optical layer 20 is transition region S, and black matrix is completely covered in transition region S
Region, and transition region S thickness is more and more thicker from the end of optical layer 20 towards center.Specifically, the bottom surface of optical layer 20 is parallel
In the upper surface of display device 10, the thickness of the transition region S outermosts of optical layer 20 is most thin.
The transition region S of the surrounding of optical layer 20 construction can have it is a variety of, preferably transition region S edge be arc fillet surface
S1, the i.e. edge of optical layer 20 have cambered surface chamfering, or, transition region S edge is the fillet surface S1 on inclined-plane, i.e. optical layer 20
Edge be chamfer.Finally, the thickness at the edge of optical layer 20 is from middle towards edge more and more thinner, play light refraction and
The effect of convergence, finally from optical layer 20 be injected into human eye display picture be in constriction black surround, play preferable visual effect.
In addition, as shown in figure 3, transition region S also has inclined plane S2 relative to fillet surface S1 closer to non-display area,
Inclined plane S2 has the smaller gradient compared to fillet surface S1, it is had further convergence effect to the region.
Display device 10 includes the backlight module 11 for providing backlight and is used to show above backlight module 11
The display panel 12 of picture, fender 30 is provided between the edge and optical layer 20 of the exiting surface of display panel 12.The fender
30 can be respectively adhered in display panel 12 and optical layer 20 by way of stickup close to the region at edge.
After the completion of display device splicing, the touch-control module of a ring shape can also be provided with the tiled display face of formation periphery
40, the touch-control module 40 is fitted in the periphery of spliced display device, it is possible to achieve the touch control operation of display device.
As shown in figure 3, the backlight module 11 of the present embodiment is direct-light-type backlight, including light guide plate 111, optical diaphragm group
112nd, backboard 113, reflector plate 114, glue frame 115, fore shell 116 and chase 117, optical diaphragm group 112 is on light guide plate 111
Side, reflector plate 114 are located at the lower surface of light guide plate 111, and the end of reflector plate 114, optical diaphragm group 112 is contained in by glue frame 115
Wherein, backboard 113 is fitted in the back side of reflector plate 114, and glue frame 115 is surrounded in it, and the end of fore shell 116 is fastened in glue frame
The surrounding of optical diaphragm group 112 is pressed on the top of light guide plate 111 by 115 top surface, its inner surface by compact heap T.
The present invention's additionally provides a kind of joining method of spliced display device, assembles display device respectively first
10, and adjacent display device 10 is stitched together, and respectively on the exiting surface of each display device 10 covered with one layer
Optical layer 20, make the transition region S of optical layer 20 that black matrix region be completely covered.Because the thickness at the edge of optical layer 20 is certainly middle
Towards edge more and more thinner, light refraction and the effect converged are played, the display picture that human eye is finally injected into from optical layer 20 is in
The black surround of constriction, play preferable visual effect.
Embodiment 2
As shown in figure 4, as different from Example 1, the fender 30 of the present embodiment is made up of light screening material, each display
Fender 30 on device 10 surrounds the annular of closing, and fender 30 is directly over black matrix region.Also, display device 10
End face and its upper surface fender 30 between there is interval, i.e. the end section of optical layer 20 stretches out in fender 30, phase
Adjacent two layers of optical layer 20 is spaced apart.Black matrix region, fender 30, the transition region of two adjacent display devices 10
Hair secondary light source 50 is provided with the region surrounded between S, secondary light source 50 is preferably arranged along the circumferentially-spaced of display device 10,
The light that secondary light source 50 is sent projects after transition region reflects, and makes the black matrix region of lower section script can still emit beam, no
It is black surround again, influences display effect without injecting viewing area through fender 30.The exiting surface of spliced display device
Again without the black surround that can not be lighted, overall display effect greatly improved.As shown in figure 4, the secondary light source 50 can be fixed on two
