Problems solved by technology

Moreover, this solution only enlarges the edge pixels and enlarges the display surface, but the size of the edge pixels is inconsistent with the central pixel, which affects the observation effect. In the future, it is necessary to adjust the pixel density or brightness of the central area and the edge area to achieve the consistency of the display as much as possible.

Embodiment 1

[0041] Such as Figure 5 Shown is a schematic structural diagram of a specific embodiment of a display device of the present invention. see figure 1 , a display device in this specific embodiment, including a display 21 with a non-luminous frame 22 on its edge, a first optical light guide layer 24 is arranged on the surface of the display 21, and a first optical light guide layer 24 is provided with a light penetrating through its upper and lower surfaces. The first through hole array, the light entrance of the through holes in the first through hole array corresponds to one or more pixels in the display 21, the light exit of the first through hole array is larger than the light entrance, and the first through hole array is defined by the center of the display. The area is set slanting towards the side borders.

[0042] Among them, such as Figure 5As shown, 26 is the display area of ​​the display 21. Since the light exit of the through hole is larger than the light entranc...

Embodiment 2

[0053] The present embodiment forms a most preferred embodiment based on embodiment 1, specifically as follows:

[0054] Such as Figure 15 As shown, 21 is a display, 22 is a non-luminous frame 22 of the display 21, 26 is a display area of ​​the display 21, 24 is a first optical light guide layer, and 27 is a diffusing screen. The length of the display area of ​​the display 21 is L1, the frame width is b0, and a first optical light guide layer is arranged above the display 21, Figure 15 The through hole in the shown first optical light guide layer 24 is a rectangular through hole, (taking the first optical light guide layer of a rectangular through hole as an example, others are similar to this), the length of the first optical light guide layer 24 is L2, L2=L1+2*b0, the thickness of the first optical light guide layer 24 is t0. The inclination angle of the first through hole array of the first optical light guide layer 24 gradually increases along the length direction of t...

Embodiment 3

[0057] On the basis of Embodiment 1 or 2, this specific embodiment also provides a second optical light guide layer on the first optical light guide layer to shield the four frames in the two-dimensional direction of the display device. Specific as Figure 17 Shown:

[0058] In this specific embodiment, a display device includes a display 21 with a non-luminous frame 22 on its edge, a first optical light guide layer 24 is arranged on the surface of the display 21, and a first optical light guide layer 24 is provided through the upper and lower surfaces of the first optical light guide layer A through hole array, the light entrance of the through holes in the first through hole array corresponds to one or more pixels in the display 21, the light exit of the first through hole array is larger than the light entrance, and the first through hole array is centered by the display 21 The area is arranged obliquely to the two side frames, and the second optical light guide layer 25 i...

Abstract

The present invention relates to the field of display screens, and more specifically, to a display device. It includes a display with a non-luminous frame on its edge, a first optical light guide layer is arranged on the surface of the display, and a first through hole array passing through its upper and lower surfaces is arranged in the first optical light guide layer, and the through holes in the first through hole array The light entrance of the display corresponds to one or more pixels in the display, the light exit of the first through-hole array is larger than the light entrance, and the first through-hole array is arranged obliquely from the central area of ​​the display to the two side frames. In the present invention, the first optical light guide layer is added on the surface of the display, and each through hole in the first optical light guide layer is arranged obliquely, and the light outlet of the through hole is larger than the light inlet, and the pixels are uniformly arranged while the display surface is raised. Zoom in so that the image information of the display can cover the frame of the display, thereby blocking the frame of the display.

Description

technical field [0001] The present invention relates to the field of display screens, and more specifically, to a display device. Background technique [0002] At present, the demand for various ultra-large display screens is increasing day by day, and their applications are becoming more and more extensive. At this stage, the realization of ultra-large display screens is mainly through splicing and displaying unit screens. Most of the display unit screens used for splicing have display frames. Taking liquid crystal displays as an example, liquid crystal displays need to be packaged with liquid crystal panels and drive wiring in the manufacturing process. As a result, the super-sized splicing display device composed of unit screen splicing display will have an obvious sense of fragmentation on the overall display screen, which seriously affects the overall display effect of the large screen. [0003] In order to realize the borderless display of the ultra-large display scr...
