Embodiment 1

[0054] Such as Figure 4a and Figure 4b As shown, it is the first embodiment of the borderless display device of the present invention, the display screen 1 has an image display area 13 and a non-luminous frame 11 positioned outside the image display area 13, the image display area 13 and the frame of the display screen 1 11 is covered with an optical component 3 whose planar geometric dimension is greater than or equal to that of the display screen 1 , that is, the optical component 3 can completely cover the display screen 1 . The optical component 3 includes an optical plate 30 and a light guide assembly 31 , the optical plate 30 is a transparent plate made of a material with good light transmission. The light guide assembly 31 is composed of several light guide sheets 310 stacked together. The light guide sheet 310 can be made of the same material as the optical flat plate 30. The light guide sheets 310 are arranged in an expanded shape, that is, the light guide assembly...

Embodiment 2

[0057] Such as Figure 5 As shown, it is a schematic structural diagram of the second embodiment of the present invention. This embodiment is further improved on the basis of the first embodiment. Specifically, the top surface of the light guide component 31 is provided with a scattering layer 316, which It is because the width of the light guide sheet 31 that constitutes the light guide assembly 31 gradually increases from the bottom surface to the top surface of the gradient structure, the light incident from the bottom surface of the light guide assembly 31 into the light guide sheet 310 passes through the two sides 313, After the total reflection of 314, the scattering angle when it emerges from the top surface of the light guide assembly 31 will decrease, which will reduce the viewing angle of the enlarged image obtained from the top surface of the light guide assembly 31, and set the top surface of the light guide assembly 31 The scattering layer 316 can increase the sca...

Embodiment 3

[0059] Such as Figure 6 As shown, it is the third embodiment of the borderless display device of the present invention. The difference from the previous two embodiments is that in this embodiment, the cross-sectional shape of the light guide sheet 310 constituting the light guide assembly 31 is the same. trapezoidal, the cross-sectional shape of the formed light guide assembly 31 is roughly trapezoidal, the top surface and the bottom surface of the light guide assembly 31 are no longer strict planes, bonding points 313 are set between the light guide sheets 310, and between the light guide sheets 310 Form air break 4. The advantage of this structure is that it only needs to process the light guide sheet 310 with a cross section, which can reduce the cost of processing and production, and reduce the manufacturing cost, especially when the light guide sheet 310 is made by molding process, it can greatly Reduce the cost of mold development and production. The other structures ...

Abstract

The invention relates to a borderless display device and a large screen displayer, wherein the borderless display device comprises a display screen and an optical element covering the display screen; the optical element comprises an optical flat and a light guide component arranged at periphery of the optical flat; the light guide component comprises a plurality of superposed light guide films which are arranged in a direction of being far away from the optical flat from a side of the optical flat; the light guide films are superposed in expanding form, and air gaps are formed among the light guide films; the light emitted from an edge display region of the display screen enters into the bottom surface of the light guide component and is output from a top surface of the light guide component after being guided by the light guide films of the light guide component, so as to form a light-emitting surface which is bigger than the bottom surface of the light guide component and is used for covering the border; and the large screen displayer is spliced by a plurality of borderless display devices. The borderless display device provided by the invention has the advantages of simple structure, excellent display effect and the like.

Description

technical field [0001] The invention relates to the field of photoelectric display, more specifically, to a frameless display device and a large-screen display. Background technique [0002] Nowadays, the demand for various super-large screen displays is increasing day by day, and splicing display is a main way to realize super-large screen display. However, due to the existence of the display screen "frame" of each single-screen display as a splicing unit when splicing display is used, the large splicing display formed has a split seam that causes a sense of division to the overall screen, which seriously affects the realized splicing display The overall effect of the picture, this problem is more serious in the "flat panel splicing" scheme that uses liquid crystal or plasma display as the splicing unit. [0003] Figure 1a and Figure 1b It is a schematic diagram of the display screen 1 of the existing (flat panel) splicing display device. Due to the limitations of displ...
