It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
Referring to fig. 1 to 3, the tiled display device of the present embodiment includes a plurality of display devices 10 and a transparent optical layer 20, all the display devices 10 are tiled together two by two, and a light emitting surface of each display device 10 is covered with a layer of the optical layer 20. The display device 10 includes a display region in the middle and a non-display region in the periphery of the display region, the periphery of the non-display region is a black matrix region (BM region), the edge of the periphery of the optical layer 20 is a gradation region S, the gradation region S completely covers the black matrix region, and the thickness of the gradation region S is gradually thicker from the end of the optical layer 20 toward the center. Specifically, the bottom surface of the optical layer 20 is parallel to the upper surface of the display device 10, and the thickness of the outermost periphery of the gradation region S of the optical layer 20 is the thinnest.
The configuration of the transition region S around the optical layer 20 may be various, and preferably, the edge of the transition region S is an arc-shaped chamfered surface S1, that is, the edge of the optical layer 20 has an arc-shaped chamfer, or the edge of the transition region S is an inclined chamfered surface S1, that is, the edge of the optical layer 20 is an inclined chamfer. Finally, the thickness of the edge of the optical layer 20 is thinner and thinner from the middle to the edge, so that the effect of light refraction and convergence is achieved, and finally, the display picture which is emitted into human eyes from the optical layer 20 is a narrowed black edge, so that a better visual effect is achieved.
In addition, as shown in fig. 3, the gradation region S also has an inclined surface S2 closer to the non-display region than the chamfered surface S1, and the inclined surface S2 has a smaller gradient than the chamfered surface S1, so that it has a further converging effect on the region.
The display device 10 includes a backlight module 11 for providing a backlight source and a display panel 12 disposed above the backlight module 11 for displaying a picture, wherein a buffer material 30 is disposed between an edge of a light-emitting surface of the display panel 12 and the optical layer 20. The cushioning material 30 may be attached to the display panel 12 and the optical layer 20 in the areas near the edges by means of adhesive.
After the display device is spliced, a circle of annular touch modules 40 can be arranged on the periphery of the spliced display surface, and the touch modules 40 are attached to the periphery of the spliced display device, so that the touch operation of the display device can be realized.
As shown in fig. 3, the backlight module 11 of the present embodiment is a direct-type backlight source, and includes a light guide plate 111, an optical film set 112, a back plate 113, a reflective sheet 114, a rubber frame 115, a front shell 116, and an iron frame 117, where the optical film set 112 is disposed above the light guide plate 111, the reflective sheet 114 is disposed on the lower surface of the light guide plate 111, the rubber frame 115 accommodates the ends of the reflective sheet 114 and the optical film set 112 therein, the back plate 113 is attached to the back of the reflective sheet 114 and surrounds the rubber frame 115, the end of the front shell 116 is clamped on the top surface of the rubber frame 115, and the inner surface of the front shell compresses the periphery of the optical film set 112 above the light guide plate 111.
The invention also provides a splicing method of the spliced display device, which comprises the steps of firstly respectively assembling the display devices 10, splicing the adjacent display devices 10 together, and respectively covering a layer of optical layer 20 on the light-emitting surface of each display device 10, so that the gradient area S of the optical layer 20 completely covers the black matrix area. Because the thickness of the edge of the optical layer 20 is thinner and thinner from the middle to the edge, the effect of light refraction and convergence is achieved, and finally, the display picture which is emitted into human eyes from the optical layer 20 is a narrowed black edge, so that a better visual effect is achieved.
Example 2
As shown in fig. 4, unlike embodiment 1, the buffer material 30 of the present embodiment is made of a light shielding material, the buffer material 30 on each display device 10 is enclosed into a closed ring shape, and the buffer material 30 is disposed right above the black matrix region. Moreover, there is a gap between the end surface of the display device 10 and the buffer material 30 on the upper surface thereof, that is, the end portion of the optical layer 20 extends out of the buffer material 30, and the adjacent two optical layers 20 are spaced apart by a certain distance. The auxiliary light sources 50 are preferably arranged at intervals along the periphery of the display device 10, and light emitted by the auxiliary light sources 50 is refracted by the gradual change area and then emitted out, so that the original black matrix area below can still emit light, is no longer a black edge, and cannot be emitted into the display area through the buffer material 30 to affect the display effect. The light-emitting surface of the spliced display device has no black edge which can not emit light, so that the overall display effect is greatly improved. As shown in fig. 4, the auxiliary light source 50 may be fixed on top of the bezel 117 of two display devices 10, and extend out to the top of the display panel 12 through the gap between two adjacent display panels 12.
According to the invention, the corresponding transparent optical layer is designed on the light-emitting surface of the spliced display device, and the special gradual change area at the edge of the transparent optical layer is utilized to carry out special treatment on the emergent light at the spliced position, so that the whole display device generates a visual effect of narrowing the black matrix area at the spliced position.
The foregoing is directed to embodiments of the present application and it is noted that numerous modifications and adaptations may be made by those skilled in the art without departing from the principles of the present application and are intended to be within the scope of the present application.
