Abstract
The utility model relates to a multimedia information display system, and particularly relates to a multimedia information display projection screen. Disclosed is the multimedia information display projection screen. The projection screen is composed of multiple unit blocks, of which the periphery is fixed with a frame. Transparent binders with same or similar refractive index and screen material are arranged among the unit blocks to bond. The size of the projection screen can be arbitrarily expanded. Besides, the binders with same or similar refractive index and screen material are adopted so that the unit block screens can be fixed by the binders, and air layers on joint parts of the unit block screens can be filled up. Because refractive index and screen material are same or similar, projection direction of projection light is not changed or obviously changed, and light is reflected on the interface so that seamless joint is realized, and excellent display quality on the joint parts is obtained.
Description
Technical field
The utility model relates to the multimedia messages display system, relates in particular to a kind of multimedia messages Display projector screen.
Background technology
Along with development, the raising of Social Culture level of education and the progress of network technology that workers and peasants produce, all need to support the high-quality giant-screen video display system of multiple network access in production scheduling command post, urban traffic control center, stadiums, audio-visual education room and the office building, auditoriums, hotels hall of industrial and mining enterprises.In recent years, the brightness of light emitting semiconductor device (LED) and light efficiency improve very fast, become the energy-saving illumination product of state key development, LED has the characteristics such as light beam is narrow, the life-span long, color variety is many, volume is little, and high-power and high-luminance LED can be used for the light source of place of gas discharge lamp as Projection Display.But no matter conventional large tracts of land monolithic screen, be glass material or high molecule plastic material, all very expensive and transportations and install all very difficult.Also have in addition and screen is divided into to several cell block peripheries fixes with framework, but the piece of this Mosaic screen not only affects good looking appearance, but also exist a more serious defect, owing at edge joint position, having air layer, the ray refractive index of the ray refractive index of air and screen material is different, throw light reflected refraction back and forth when two interfaces of splicing seams, cause edge joint position to show that image is discontinuous, grievous injury the video display quality of image.
Summary of the invention
In order to solve above-mentioned technical matters, the purpose of this utility model is to provide a kind of multimedia messages Display projector screen.This projection screen can not change or obviously change the projecting direction of projection light, and causes light reflection in interface, realizes seamless splicedly, and obtains good display quality in splicing place.
In order to realize above-mentioned purpose, the utility model has adopted following technical scheme:
Multimedia messages Display projector screen, described projection screen consists of the polylith cell block, and the cell block periphery is provided with framework and fixes, and is provided with identical with the screen material or the close translucent adhesive of refractive index bonding between cell block and cell block.
As further improvement, by the physics sandblast, with chemical corrosion, combine to the milky white processing of glass surface, obtain the reflection and transmission glass surface texture evener than controlled De Zhuo, significantly improve display performance and effect, adapt to the display requirement of varying environment.
As further improvement, in order to ensure the safety of large display screen curtain, the whole screen surface of projection screen is pasted with diaphragm, in screen is cracked, and unlikely people and the thing that hurts screen periphery.
As further improvement, described cell block is glass material, and translucent adhesive adopts the modified epoxy that refractive index is 1.5 ~ 1.6.
The large I arbitrary extension of the utility model projection screen, adopt the tackifier that refractive index is identical or close with the screen material simultaneously, it can not only gluing fixed cell piece screen and air layer that can filling cell block screen splicing place, because refractive index is identical with the screen material or close, can not change or obviously change the projecting direction of projection light, and cause light reflection in interface, and realize seamless splicedly, and obtain good display quality in splicing place.
The accompanying drawing explanation
The structural representation that Fig. 1 is the utility model system.
The syndeton schematic diagram that Fig. 2 is two cell blocks of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is made a detailed explanation.
As shown in Figure 1 and Figure 2, but this display system screen size arbitrary extension of the utility model adopts a kind of projection screen of splicing structure, screen is divided into to several cell blocks 2 peripheries fixing with frameworks 1, and cell block 2 adopts glass materials.Simultaneously, adopt the refractive index tackifier 3 identical or close with the screen material, tackifier 3 adopts the modified epoxy that refractive index is 1.5 ~ 1.6, it can not only gluing fixed cell piece 2 screens and air layer that can filling cell block 2 screen splicing places, because refractive index is identical with the screen material or close, can not change or obviously change the projecting direction of projection light, and cause light reflection in interface, realize seamless splicedly, and obtain good display quality in splicing place.Further the utility model combines with chemical corrosion by the physics sandblast to the milky white processing of glass surface, obtains the reflection and transmission glass surface texture evener than controlled De Zhuo, significantly improves display performance and effect, adapts to the display requirement of varying environment.In addition, in order to ensure the safety of large display screen curtain, the whole screen surface of glass material is mounted to diaphragm 4, in screen is cracked, unlikely people and the thing that hurts screen periphery.
