Front maintenance type back casting large screen display unit capable of remote control adjusting light path

Abstract

The invention relates to a front load remote control adjusting light path back projection large screen display unit, which comprises a forward lead tipping screen, a left right knighthead, a left right side movable facing bar, a left right side runner, a left right side shoe plate, a synchronous joint lever, an imaging device, an adjusting device, and a building block system stacking structural case. The left right knighthead, left right side movable facing bar, the left right side runner, the left right side shoe plate, the synchronous joint lever and the imaging device are arranged inside the building block system stacking structure case. The invention improves the rear load building block system stacking structure case display unit exists in present market and at the same time, the invention also improves the front load case display unit which can be matched into two layers existing in present market so that saving backside maintaining space, adjusting and maintaining from the front, and realizing N*M stacking effect with arbitrariness can be realized. Therefore, the invention is a building block system front load remote control adjusting picture display unit which can satisfy all the functions in present markets.

Description

technical field [0001] The invention relates to a rear projection display device, in particular to a rear projection large-screen display unit of a front maintenance type remote control optical path adjustment. Background technique [0002] The rear-projection large-screen display wall is a building block structure composed of N (number of layers)×M (number of cases) display unit boxes. The image it displays is one (multiple) screens divided into N×M by digital technology. After the small picture is transmitted by digital technology, it is assembled into a complete large picture on the display wall. Therefore, each cabinet is required to be light in structure, reliable in load bearing, easy to install, and good in interchangeability. At the same time, it is also required to have reasonable wiring without interference, dust-proof, light-proof and ventilated. At present, the cabinets combined into the display wall adopt the rear debugging structure, that is, a space of not le...

AI Technical Summary

Problems solved by technology

Display units using this technology can only achieve stacking of no more than two layers in the application of display wall splicing, which will affect the display area of ​​the display wall

Moreover, the display wall spliced ​​into the second floor will occupy the space on the upper and lower sides of the display area at the same time, which will limit the on-site construction; although two people cooperate to debug the image, the operation is reduced to one person, but one person needs to repeatedly run back and forth between the debugging position and the observation position Time-consuming

And it fails to achieve the effect of rear projection large-screen display wall composed of N×M display unit cabinets (so it can only be called a wide-screen display wall, which can only meet the splicing of 2×M)
