Abstract
The utility model relates to a portable high-brightness projection screen, comprising a high-luminance projection screen and a portable star-shaped bracket. The high-brightness projection screen comprises a high-brightness reflecting material layer of 0 degree watching angle, brightness coefficient of 100-2000 and image resolving power of 20-500 line pairs / mm and a screen protecting layer covered at the back of the layer. A plurality of through holes for erecting the screen are arranged at four sides of the high-brightness projection screen. A flexible screen border is arranged in front of the through hole. The portable star-shaped bracket is composed of a telescopic supporting bar which can be detached and installed and a star-shaped base. The portable high-brightness projection screen is flexible and collapsible, with the advantages of small volume, light weight, high screen reflecting brightness, good projecting effect, quick installation and convenient carrying. The portable high-brightness projection screen is very suitable for using in flowing commercial activities, and the application prospect is wide.
Description
Technical field
The utility model relates to a kind of projection screen, is specifically related to a kind of portable high-brightness projection screen.
Background technology
Along with the development of video frequency projector is popularized, utilize projector equipment to come the promotional commodity by the screen picture, be an important means of present commercial sales promotion, the sales force just need carry light projector equipment in order to carry out on-the-spot demonstration when paying the client a visit.Although very little being very easy to that the volume of present projector has been done carried, as the projection screen of projector equipment important component part, volume and weight is but not as people's will, and is very inconvenient when carrying.Its weak point is: one, existing portable translucent screen all is the Scroll structure, and the big spool of screen area is long more not portable more, and portable short spool projection screen is difficult for watching because of picture is little; Two, existing portable translucent screen reflecting brightness coefficient is low, and the image resolving power is poor, and project effect is undesirable in bright chamber; Three, existing portable translucent screen has the spool enclosure structure, has increased the volume and weight of screen.
Therefore, existing portable translucent screen can not have been satisfied the demand of various mobile commercial activity demonstrations, but the big Fast Installation dismounting of the little developed area of a kind of packaging volume of market demand, while reflecting brightness height, the novel portable projection screen that the image resolving power is strong, drop shadow effect is good.
Summary of the invention
In order to overcome the weak point that existing Scroll portable projection screen exists, the utility model provides a kind of portable high-brightness projection screen that need not spool, be characterized in: the projection screen ultra-thin flexible can fold, and not influenced by screen breadth size, and the little developed area of packaging volume is big; Use the high-brightness screen material, the reflecting brightness height, the image resolving power is strong, drop shadow effect good; Adopt rice font telescope support to install, simple and fast is convenient; The screen bare structure is in light weight to be easy to carry, and is particularly suitable for mobile commercial activity and carries out big image projection use.
The utility model addresses the above problem the scheme of being taked: a kind of portable high-brightness projection screen includes high-brightness projection screen and portable rice font support, it is characterized in that: the thickness of high-brightness projection screen is that 0.01～1mm softness is collapsible, 0 ° is watched the angular brightness coefficient is 100～2000, the image resolving power be 50～500 lines right/the mm high-brightness projection screen is made up of reflections of high brightness material layer and the screen protective seam that covers thereafter, four limits at high-brightness projection screen are provided with the perforation that several set up screen, are provided with flexible screen frame in the front of perforation; Portable rice font support is made up of 8 detachable telescopic supporting rods of installing and rice font seat, and the collapsing length scope of telescopic supporting rod is 20～200cm, is provided with the screen hook on its top.
When screen is installed, at first 8 telescopic supporting rods are connected with rice font seat, every telescopic supporting rod are stretched to the length of run of regulation by the shortest withdrawal length; Secondly the significantly high-brightness projection screen with folded state launches, and the reflections of high brightness material layer up, the screen protective seam covers on the portable rice font telescope support down; Then flexible screen frame is started, the screen of its back perforation is hung on the screen hook on every telescopic supporting rod top; By extending the length of adjusting every telescopic supporting rod, make the exhibition of stretching tight gradually of whole screen plane reach smooth projection requirement at last, install the beginning projection is vertically placed in screen.Projection finishes, and the opposite sequence operation just can be with the fast quick-detach of screen.
The utility model has the advantages that: adopt soft folding reflections of high brightness material projection screen, removed heavy spool, make significantly screen carry out FOLD AND PACK and volume is especially little; Adopt a rice font support that a screen is installed, not only simple and quick but also make act face easily smooth; Screen reflecting brightness coefficient height, image resolving power are strong, and bright chamber projection project effect is good; In light weight being easy to carry.

Embodiment
A kind of portable high-brightness projection screen includes high-brightness projection screen (1) and portable rice font support (2), it is characterized in that: the thickness of high-brightness projection screen (1) be 0.3mm very softness can fold, 0 ° is watched the angular brightness coefficient is 500, the image resolving power be 150 lines right/mm; High-brightness projection screen (1) is made up of reflections of high brightness material layer (3) and the screen protective seam (4) that covers thereafter, be provided with several perforation of setting up screen (5) on four limits of high-brightness projection screen (1), be provided with flexible screen frame (6) in the front of perforation (5); Portable rice font support (2) is made up of 8 detachable telescopic supporting rods of installing (7) and rice font seat (8), and the collapsing length scope of telescopic supporting rod (7) is 20～200cm, is provided with screen hook (9) on its top.
When screen is installed, at first 8 telescopic supporting rods (7) are connected with rice font seat (8), every telescopic supporting rod (7) are stretched to the length of run of regulation by the shortest withdrawal length; Secondly the significantly high-brightness projection screen (1) with folded state launches, and reflections of high brightness material layer (3) up, screen protective seam (4) covers on the portable rice font support (2) down; Then flexible screen frame (6) is started, the screen of its back perforation (5) is hung on the screen hook (9) on every telescopic supporting rod (7) top; By extending the length of regulating every telescopic supporting rod (7), make the plane exhibition of stretching tight gradually of whole high-brightness projection screen (1) reach smooth projection requirement at last, install the beginning projection is vertically placed in screen.Projection finishes, and the opposite sequence operation just can be with the fast quick-detach of screen.
