Abstract

A splicing-free oversize-screen display system relates to a screen display system and comprises an outer frame, a rear projection screen, buffer springs, a DLP (Digital Light Processing) engineering projection machine, an image processing system, a decoder, a supply fan, an exhaust fan, a temperature control switch and an optical reflection mirror, wherein a black matte paint layer is sprayed in the outer frame; an air inlet hole is formed at the position below the left side surface of the outer frame; the supply fan is arranged in the air inlet hole; an exhaust hole is formed at the position above the right side surface of the outer frame; the exhaust fan is arranged in the exhaust hole; the rear projection screen adopts a splicing-free rear projection screen which is arranged on the front side of the outer frame; the buffer springs are arranged at the four edges of the rear projection screen; the engineering projection machine, the image processing system, the decoder, the temperature control switch and the optical reflection mirror are arranged in the outer frame; an edge-blending device and a multiscreen image processor are arranged on the image processing system; and the input end of the edge-blending device is connected with the output end of the multiscreen image processor, the output end of the edge-blending device is connected with the DLP engineering projection machine, and the input end of the multiscreen image processor is connected with a signal source.

Description

technical field [0001] The invention relates to a screen display system, in particular to a high-definition intelligent non-splicing super large screen display system. Background technique [0002] Since the advent of the first spherical display in the last century, people have continued to explore and research in the field of display terminals, and have invented and created many types and characteristics of display terminals, such as liquid crystal displays, LED displays, rear projection TVs, plasma TVs, etc. ; But now people's demand for information is increasing, and the level of appreciation is getting higher and higher, and the requirements for large-scale display systems in various fields have become the mainstream irresistibly. [0003] At present, the main large-scale display systems on the market include LED splicing walls, LCD splicing walls, plasma splicing walls, DLP rear projection splicing walls, and display walls without physical gaps introduced in recent year...

AI Technical Summary

Problems solved by technology

[0003] At present, the main large-scale display systems on the market include LED splicing walls, LCD splicing walls, plasma splicing walls, DLP rear projection splicing walls, and display walls without physical gaps introduced in recent years; the splicing seams of various types of splicing walls will inevitably affect the viewing effect of the screen , and the splicing wall generally has the problem of unstable seam size and inconsistent color of the split screen

[0004] The principle of the display wall without physical gaps that has appeared in recent years is the rear projection screen, which adopts a whole without physical gaps. The rear projection of the screen is projected by multiple projectors. The inner edges of the correction frame are the same, so that the entire screen can be displayed without physical gaps; although this kind of display wall eliminates the problem of splicing seams in the picture, but the angles of each projector relative to the audience on the screen are different, and the final audience sees The images projected by each projector in the screen, especially at the edge of the screen, have obvious differences in color and brightness, and there are also problems with the stability of the screen.

[0005] There is also a type of rear projection display wall on the market, which uses edge fusion technology to fuse several rear projection units into a single screen to achieve a large screen without splicing. There are often defects such as uneven screen, unstable fusion band, and single function
