Multi-screen spliced seamless display screen

Abstract

The invention discloses a multi-screen spliced seamless display screen. The multi-screen spliced seamless display screen comprises at least two mutually spliced display units, wherein image processing modules of the same size are laminated on the surface of each display unit, are a Fresnel lens, a cylindrical lens, a magnifier or an optical lens and are additionally overlapped by optical processing modules; the optical processing modules are anti-dazzle glass, organic glass, an acrylic plate, a resin material or an anti-scratch lens; the display units, the image processing modules and the optical processing modules are wrapped by a fixing module for fixed connection. The seamless splicing of the display units are truly realized, so that the integral performance of an image displayed by the display screen is just right, the situation of mismatch of pictures and characters produced during precise image-text display can be effectively prevented, and the sense of projection in vision is eliminated.

Description

technical field [0001] The invention relates to the technical field of large-screen splicing display, in particular to a multi-screen splicing seamless display screen. Background technique [0002] At present, the known large-screen splicing display technology is usually formed by simple physical splicing of independent display units such as LCD, DLP, and PDP. Two adjacent splicing units are physically spliced ​​by aligning and squeezing. Since the display units are simple Independently packaged, a relatively large seam will be formed after being spliced ​​into a large screen. When displaying precise graphics and texts, the picture and text will be dislocated due to screen splitting, which will greatly affect the image display effect and full-screen viewing effect. [0003] At present, there are three ways to deal with this patchwork at home and abroad: the first is to add LED dot matrix to the frame of the display unit, this method has poor effect when displaying text files...

AI Technical Summary

Problems solved by technology

This technical solution is the third method described, but the defect of the technical solution is that by setting the edge chamfer of the optical module (4) to 45°~60°, the refracted light cannot completely fill the physical seams, and in the near When viewed from a distance, the physical patchwork cannot be completely avoided, and the optical module is simply used to simply enlarge and fill the image. The entire display screen will still have a raised feeling visually, which will affect the display effect of the entire screen and needs to be improved.
