Abstract
The utility model relates to a suspension rear projection screen capable of forming high-resolution images in the front and the back surfaces simultaneously, which comprises a semi-transparent light-black optical hemispherical surface reflection crystal lens layer, a light absorbing layer, a rear projection screen body and a diffuse reflection lens plan-view imaging layer. (Note that the surface of the incident light of a projector is tentatively defined as the back surface.) The utility model is characterized in that the semi-transparent light-black optical hemispherical surface reflection crystal lens layer comprises semi-transparent light-black optical hemispherical surface reflection crystal lenses, the thickness of the lenses is 50-80um, the radius of the hemispherical surface reflection crystal is 40-70um, the thermo-plastic optical base material comprises the light-black ambient light absorbing layer or the grey-black or the coffee ambient light absorbing layer, and the thickness of the screen is 3-5mm. The utility model has the advantages that the rear projection screen can form the images in the front and the back surfaces simultaneously, the images are clear and stable, the screen can be utilized to propagate, and viewers can see the propaganda content from the front and the back surfaces simultaneously, thereby improving propaganda effect.
Description
Technical field
The utility model relates to a kind of rear projection screen, refers more particularly to the suspension type rear projection screen of tow sides imaging simultaneously.
Background technology
At present existing projection screen display technique field, normally front projection screen or rear projection screen, front projection screen and rear projection screen all have a kind of shortcoming, and it can not tow sides high-resolution imaging simultaneously, if it is suspended on the gold position of commercial field, it has the defective of back side visual dead angle.Along with social economy constantly develops, particularly at commercial field, as, bar, market, airport, station, harbour etc. have the very big market demand to the rear projection screen of suspension type tow sides energy while high-resolution imaging.
Summary of the invention
The utility model purpose is, invents a kind of tow sides suspension type rear projection screen of high-resolution imaging simultaneously, to meet the need of market.
The utility model adopts following technical proposals for achieving the above object: a kind of tow sides are the suspension type rear projection screen of high-resolution imaging simultaneously, is made up of translucent light/dark balance optics hemisphere face reflection crystalline lens layer, the translucent light-absorption layer of light/dark balance, rear projection screen body and diffuse reflection lens front imaging layer successively.(annotate: this face of projector's incident ray is tentative to be reverse side) is characterized in, translucent light/dark balance optics hemisphere face reflection crystalline lens layer is made up of the translucent optics hemisphere face reflection of light/dark balance crystalline lens, lens jacket thickness 50-80um, hemisphere face reflection crystal radius 40-70um, thermoplasticity optical sheet type base material is made up of light/dark balance surround lighting light-absorption layer, also can be grey black or coffee-like surround lighting light-absorption layer, screen thickness be between 3-5mm.
The beneficial effects of the utility model are:
(1) rear projection screen tow sides imaging simultaneously;
(2) clear picture is stable;
(3) utilize this kind screen to do propaganda, spectators can see promotional content by tow sides, have enlarged the effect of publicity.
