Abstract

A light guide image amplifying screen comprises a front-end transparent layer, a fiber transmission layer, a micro-lens layer and a back-end transparent layer through compounding. Wherein, the micro-lens layer serves as an image amplifying lens and directly attached to a top of a fiber end. Fiber diameter of the fiber transmission layer is even or variable. The screen is designed into a ladder-like structure with thickness of 5 to 100 mm according to size of frames without images around the screen to form a light guide amplifying and imaging screen connected with an assembling frame in back of the screen without influencing image transmission, provided with a large cross section on one side and a small cross section on the other side and showing a ladder-like appearance at thickness direction, thus eliminating screen assembling seams. The present invention has the advantages of completely removing physical seams, reducing optical seams to 0 to 0.2 mm and ensuring continuity, intactness and excellent appreciation of assembled images.

Description

technical field

[0001] The invention belongs to the field of video technology, such as video seamless splicing technology, video large-screen splicing is suitable for video monitoring, combat command, simulation, TV stations, exhibitions, large-scale public demonstrations and other places, and has a wide range of uses. technical background

[0002] At present, the splicing modes with small video splicing gaps on 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. inch, 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 gener...
