Problems solved by technology

[0005] The existing seamless splicing technology mainly adopts hard-edge splicing and overlapping splicing. The black seam of splicing the large screen will not only split the image of the flat large screen, but also the black seam will be easily misunderstood as part of the image, and even give high-end Surveillance made a misjudgment

Embodiment 1

[0028] A method for removing black seams for multi-screen splicing, comprising the following steps:

[0029] Step 1: Use thermoplastic technology to mold the acrylic plate into a trapezoid structure, specifically: firstly arrange the low-refractive index material and high-refractive index material in the mold, and then heat and hot-press to form the trapezoid body. Then carry out edge cleaning and surface treatment on the composite ground glass formed by composite; the surface and surrounding of the composite ground glass formed by hot pressing should be ground and polished to above 400 mesh, and then surface treatment agent and composite glass surrounding treatment agent should be sprayed. The number of plates is 9, arranged in a 3×3 matrix.

[0030] Step 2, tile and bond the two acrylic sheets together;

[0031] Step 3: Lay the glass on the front of the two acrylic sheets that are tiled and bonded together in Step 2;

[0032] In step 4, the glass-coated acrylic sheet that ...

Embodiment 2

[0034] like figure 1 As shown, a structure for removing black seams for multi-screen splicing includes two acrylic boards 1 that are fixed and stacked together, and the shape of the acrylic boards 1 is a trapezoidal structure. The glass 2 is also included, and the glass 2 is attached to the front surface of the acrylic plate 1 . The acrylic plate 1 contains high refractive index material and low refractive index material. The shape of the low-refractive-index material is sheet-like; its thickness is not greater than one-tenth of the pixel pitch of the applicable display screen. The shape of the high-refractive-index material is sheet-like; the high-refractive-index material is a highly transparent material, and its light transmittance should be greater than 85%; when the high-refractive-index material is sheet-like, its thickness is not greater than the pixel of its applicable display screen point spacing. The glass 2 is a touch screen.

Embodiment 3

[0036] like figure 1 As shown, a structure for removing black seams for multi-screen splicing includes two acrylic boards 1 that are fixed and stacked together, and the shape of the acrylic boards 1 is a trapezoidal structure. The glass 2 is also included, and the glass 2 is attached to the front surface of the acrylic plate 1 . The acrylic plate 1 contains high refractive index material and low refractive index material. The shape of the low-refractive-index material is honeycomb; its thickness is not greater than one tenth of the pixel pitch of the applicable display screen. The shape of the high-refractive-index material is a granular shape smaller than the diameter of the honeycomb hole of the low-refractive-index material; the high-refractive-index material is a highly transparent material, and its light transmittance should be greater than 85%; when the high-refractive-index material is a flake, its The thickness is not greater than the pixel pitch of the display scree...

Abstract

The invention discloses a method and structure for removing multi-screen splicing black seams, and belongs to the technical field of splicing screen seamless splicing. The method includes the steps that firstly, acrylic boards are made into a trapezoid structure through the thermoplastic technology, wherein a material low in refractive index and a material high in refractive index are distributed in a mould and then heated and subjected to hot press molding to form a trapezoid body, and after demoulding, composite ground glass formed in a composite mode is subjected to edge cutting and surface treatment; the surface and periphery of the composite ground glass obtained through hot press molding is ground and polished to 400 mesh or above, then a surface treating agent and a composite glass periphery treating agent are sprayed, the number of the acrylic boards is nine, and the acrylic boards are distributed in a 3*3 array; secondly, two acrylic boards are horizontally laid and attached together; thirdly, glass is attached to the front sides of the two acrylic boards which horizontally laid and attached together in the second step; fourthly, the acrylic boards attached with the glass in the third step are attached to the outer surface of a splicing screen.

Description

technical field [0001] The invention relates to a seamless splicing technology for splicing screens, in particular to a method and structure for removing black seams in multi-screen splicing. Background technique [0002] With the continuous integration and development of display technology and control technology, in the high-end engineering field, the large-screen image display formed by splicing has been widely used. The display effect has greatly improved the work efficiency in the fields of monitoring, security, conference, simulation and simulation, and at the same time promoted the rapid progress of the technical level of these industries. [0003] In the display and control technology mainly based on splicing, the seamless splicing technology used to realize the seamless fusion and display of images is one of the important technologies. In recent years, with the development of software and hardware technology, seamless splicing technology has entered a very mature st...
