Abstract
The utility model relates to a rear-projection screen with perspective effect. Tiny-bead-shaped crystal substances which are evenly distributed in methacrylate ester screen material is displaying layers of the screen. The screen has a perspective characteristic because of moderate transparent structural performance. The whole screen is blue or brown, and the thickness of the screen material is determined by the size of the screen material. The screen is hung in general, and the screen can display dynamic images, and goods displayed behind the screen can be seen through the perspective effect.
Description
Affiliated technical field
The utility model is about projection screen, particularly has the rear projection screen of transparent effect.
Background technology
Projection screen has front projection screen and rear projection screen, and front projection screen is by front projection and at the positive surface imaging of screen, rear projection screen by the back projection at the positive surface imaging of screen.Therefore general screen all shelters from the space of back.Relatively be applicable to meeting room, conference hall, Surveillance center, the occasion that multi-media classroom or the like space is bigger.To the shop, the market, amusement and leisure center or the like commercial space just not too adapts to.Because of screen can block generations such as displaying merchandises, so can not be fully used in the space.
