Seamless split joint video frequency wall

Abstract

A seamlessly assembled video wall belongs to the field of seamless video assembling comprises a video source, an image amplifying and light guide screen and a connecting frame. Wherein, the video source can be a projector, a liquid crystal TV, a plasma TV, a CRT TV or other types of video equipments. The image amplifying and light guide screen is a ladder-like structure with thickness of 5 to 100 mm. In addition, cube width and height of a video source incidence surface of the image amplifying and light guide screen is 0.5 to 50 mm smaller than cube width and height of an imaging surface. The image amplifying and light guide screen is made from fibers and fastened at a back end of the screen imaging surface. The whole ladder-like structure of the screen excluding 0.1 to 5 mm size in back of the imaging surface is wholly embedded into the connecting frame to realize seamless screen image assembling. The present invention has the advantages of eliminating physical seams of a plurality of same video sources and protecting image intactness and continuity. The large screen image after the assembling brings better appreciation effects.

Description

technical field [0001] The invention belongs to the field of video seamless splicing, and in particular provides a seamless splicing video wall. It is suitable for video surveillance, combat command, simulation, TV station, exhibition, large-scale public demonstration and other places. technical background [0002] At present, the video splicing modes with small gaps in the market are mainly rear projection and plasma splicing. The projected types include DLP optical machine rear projection, which is limited by the brightness of the optical machine. The main sizes are 50 inches, 60 inches, and 67 inches. , the splicing gap is about 1.5 mm; the second is super-large screen splicing, the screen size is generally 84 inches, 100 inches, 120 inches, 150 inches, and the screen splicing gap is generally about 5 mm; the third is CRT rear projection splicing mode , limited by the brightness of the CRT projection gun, the size of the general splicing unit is within 60 inches, and the...
