Description

A kind of seamless spliced high image quality large-screen display of arbitrary surface plane

[technical field]

The present invention relates to a kind of high image quality large-screen display more particularly to a kind of seamless spliced high image quality of arbitrary surface plane Large-screen display.

[background technique]

Large-screen display is the important component that modern video shows screen, mostly with LED screen, rear projection screen, liquid crystal Flat panel TV, plasma flat-screen televisions etc. are spliced.There is point away from excessive, colour gamut is narrow, display image quality is deficient in traditional LED screen It is good, be not suitable for interior display high image quality content;It will appear excessive light decay after prolonged use, need integral replacing, cost Higher deficiency;The presence such as traditional rear projection screen, liquid crystal flat-plate television, plasma flat-screen televisions can not be accomplished seamless spliced and appoint Meaning curved-surface display, waterproof, anti-collision performance are poor, and are not used to outdoor occasion, maintenance, the higher deficiency of replacement cost;Tradition Large-screen display exists to realize touch-control, handwriting functions, generally requires additional increase touch panel, will make display display effect Fruit declines and is greatly reduced the waterproof of display, anti-collision performance, and it is even more impossible to the deficiency of flexible displays is made.

As patent document CN102339565A, CN103295481A, CN104123893A announce it is several seamless spliced aobvious Show device, principle is to realize using supplementary type or superposing type display module is installed additional and fill up or block flat-panel monitor splicing seams Purpose.There are display pixel points away from uneven, image quality consistency is not good enough, production and assembly step is various, waterproof is anti-for the series technique The poor deficiency of collision performance.

As patent document CN101706623A, CN102542919A, CN102646407A, CN103293722A, CN103996360A, CN104123885A announce several seamless splicing displays, principle be using install additional refraction type prism, The optical elements such as cylindrical mirror or reflecting mirror realize the purpose for visually blocking flat-panel monitor splicing seams.The series technique exists aobvious Show pixel away from uneven, image quality consistency is not good enough, picture has the deficiencies of distortion, visible angle is smaller.

[summary of the invention]

It is a primary object of the present invention to solve existing large-screen display be not able to achieve really it is seamless spliced, image quality is not good enough, It is difficult to make the deficiency of flexible displays etc., proposes a kind of seamless spliced high image quality large-screen display of arbitrary surface plane.

The present invention is achieved through the following technical solutions: a kind of big screen display of seamless spliced high image quality of arbitrary surface plane Show device, is piled up and formed by multiple bricked optical fiber back projection type display modules, the element packet of the bricked optical fiber back projection type display module Include variable cross-section fibre faceplate, signal processing module, LCD panel, LED light source module, fixed device and shell, anti-dazzle frosted Coating, touch sensing board, the variable cross-section fibre faceplate are located on the outside of optical fiber back projection type display module, the variable cross-section fiber facet The content of LCD panel is projected to the surface of optical fiber back projection type display module, the liquid crystal by optical fiber transmission mode by plate Show that plate is located at variable cross-section fibre faceplate rear end, the vision signal from signal processing module is shown in translucent panel In, the LED light source module is located at LCD panel rear end, provides backlight for display, the signal processing module is located at Between the variable cross-section fibre faceplate and LCD panel, display signal is provided for LCD panel, and take into account variable cross-section optical fiber The fixed function of panel and LCD panel, variable cross-section fibre faceplate rear end is equipped with fixed device and shell, described anti-dazzle Frosted coating is located at optical fiber back projection type display module outer surface, plays the effect anti-dazzle to ambient, the touch sensing board On the outside of the variable cross-section fibre faceplate, touch-control positioning signal can be provided for large-screen display.

Further, the variable cross-section fibre faceplate includes high transparency variable cross-section optical fiber, lightweight filler, Ruo Gangen The high transparency variable cross-section optical fiber is arranged through die bundling, after pouring into lightweight filler solidification, on the inside of variable cross-section optical fiber Section, variable cross-section outer fiber section surface cut, polished, polished, bricked variable cross-section fibre faceplate is made, without appoint What fixture or shell can be such that many close fiber optics arrange and solidify;The variable cross-section outer fiber of the high transparency variable cross-section optical fiber Diameter of section is greater than variable cross-section optical fiber inside cross-sectional diameter, and the pixel of variable cross-section optical fiber inside cross-sectional diameter and LCD panel Point realizes that point-to-point one-to-one correspondence is guide-lighting, the variable cross-section outer fiber diameter of section is that is, the large-size screen monitors are shown away from equal The actual displayed pixel of device is away from the lightweight filler is located at the high transparency variable cross-section optical fiber surrounding, plays filling Optical fiber gap and solidification.
