Abstract
The utility model relates to a curtain type flexible and soft projection screen with high light brightness, comprising a flexible light reflecting layer with high brightness, a seaming paste layer and a bottom curtain protecting layer of the projection screen. The thickness of the flexible light reflecting layer with high brightness is 0.25 mm. The brightness coefficient of 0 degree viewing angle is 350. The image resolving power is 120 line pairs/mm. The seaming paste layer connects and fixes more than two flexible light reflecting layers with high brightness to form a large projection screen, and the back of the large projection screen is covered by the bottom curtain protecting layer of the projection screen. The curtain type flexible and soft projection screen with high light brightness is extremely soft, and can be suspended like a curtain. The reflecting brightness coefficient is high. The utility model is especially suitable for the home slide projector with small power. The manufacture cost is low, and the use is easy.
Description
Affiliated technical field
The utility model relates to a kind of front projection image reflection device, is specifically related to the flexible soft high-brightness projection screen of a kind of window curtain type.
Background technology
Along with developing rapidly of digital video projector is universal, a lot of people wish to utilize this digital equipment to set up the home theater of oneself, view and admire the image of oneself liking by big screen projection, to obtain visual enjoyment on the spot in person.Therefore, select a suitable family expenses projection screen and seem extremely important when procuring equipment, the reflecting brightness coefficient of the screen that should consider also will be considered the mode of installing and using of screen and the convenience that transportation is carried.Though have the plurality of specifications model available with projector supporting projection screen in the market, the Scroll projection screen that but the contour structures of these products all is a upper and lower volume to be put, overall volume is relatively heavier, its weak point is: screen has adopted the thicker cloth sill that can not fold to manufacture, in transportation, installation and use, can only be fixed to be wrapped in to roll up on the very long spool and put, the screen area is big more, spool is just long more, transportation is installed and used also just inconvenient more, generally is not suitable for family and uses.In addition, these screens are lower for low power home projector reflecting brightness, and projected picture does not just reach desirable brightness effects slightly greatly during projection.
Summary of the invention
In order to overcome the weak point that existing Scroll projection screen exists at civil area, the utility model provides a kind of and has installed as curtain, need not spool---the flexible soft high-brightness projection screen of window curtain type, not only the convenient transportation use is simple for it, and the reflecting brightness height, be particularly suitable for the miniwatt home projector and carry out big image projection use.
The utility model addresses the above problem the scheme of being taked: the high brightness traffic safety reflectorized material that utilizes a kind of ultra-thin flexible, make the flexible soft high-brightness projection screen of window curtain type, it includes curtain protective seam at the bottom of flexible high-brightness reflective material layer, piece adhered layer and the screen, it is characterized in that: the thickness of flexible high-brightness reflective material layer is 0.01～0.5mm, watching the angular brightness coefficient at 0 ° is 100～1000, the image resolving power be 50～300 lines right/mm; When making the large tracts of land projection screen, the reflective material layer more than two is carried out the piece butt joint, and closely be connected and fixed with the piece adhered layer at its back side; The curtain protective seam carries out covering protection in the back of flexible high-brightness reflective material layer to it at the bottom of the screen; Be provided with several rope perforation in the top of screen, can reeve as curtain and hang the fixing screen of using.
The beneficial effects of the utility model are: adopt very thin flexible high-brightness reflectorized material to make soft projection screen, removed heavy spool, make screen can fold flexible packaging, transportation volume is especially little; Adopt window curtain type to hang and install, simple to operate easy to use; Screen reflecting brightness coefficient height, image resolving power are strong, use the miniwatt projector equipment just can see the big picture presentation effect of high brightness; Low cost of manufacture is convenient to popularization and application.
