Seamless assembly large screen displayed with multi-unit image and assembly method thereof

Abstract

The invention provides a seamless assembly large screen displayed with multi-unit image and an assembly method thereof, belonging to the field of large-screen assembly technique. The large screen is formed by the assembly of a group of display units and is characterized in that the mainbody surface of the surface glass substrate of the display unit is a planar structure; the edge surface of the surface glass substrate is an arc structure of the same specification; arc surfaces of adjacent sides of all display units are symmetric correspondingly to the joint center; each display unit is matched with an image rectifier which is connected with image input data; the seamless assembly large screen displayed with multi-unit image and assembly method thereof utilize non-uniform image density display, optical principle and image distortion rectification technique to eliminate the assembly seam on the large screen; furthermore, as the display units have the same specification and can be mass-produced, the production cost is reduced, the installation is convenient and the quality is stable.

Description

technical field [0001] The invention belongs to the technical field of splicing of large screens, in particular to a large screen with seamless splicing of multi-unit image display and a splicing method thereof. Background technique [0002] At present, super large screens at home and abroad are all made of simple physical splicing of independent display units such as LCD, PDP, and DLP. Since the display units are all relatively independent packages, when two or more display units are spliced ​​into a large screen, relatively large gaps are formed at the joints of the screens, which affects the visual effect of the picture. [0003] At present, there are two ways to deal with this kind of gap at home and abroad: one is to use ultra-thin materials for the packaging of the display unit in order to reduce the screen splicing gap. This method can only reduce the splicing gap, but cannot eliminate the gap, and the gap The size depends on the technical level of the installer and ...

AI Technical Summary

Problems solved by technology

The latter method is more feasible in theory, but it is poor in operability in actual engineering. The reason is that there are often many independent display units in a large-screen system, and the lens added to the display unit in the middle of the entire screen cannot be fixed; due to the color temperature of each independent unit There will be some differences in chromatic aberration, especially after long-term operation, the degree of aging will be different, so the requirements for the optical curvature of the lens will be different; in the actual installation process, the gaps of the screen cannot be uniform, so it is necessary to install on the screen After completion, the lens corresponding to the independent display unit is processed separately according to the measurement results, and because the parameters of each lens are different, it cannot be mass-produced, the production cost is high, the construction period is long, and the quality is not reliable
