Abstract
The utility model relates to an improved micro-pearly paling gilding screen, comprising calico (1), a polyvinyl chloride resin coating (2) and a metal coating (3). The surface of the screen is composed of a plurality of miniature convex surfaces which are arranged orderly. The screen has high brightness and large level light distribution angle, the effect of projection picture watched by both sides viewers is fundamentally the same with the effect of front projection picture. The utility model is not only suitable for showing various films, but is also suitable for a lantern, a television and teaching projection, etc.
Description
The utility model relates to a kind of improved screen, particularly the screen of microballon formula convex surface plating.
What generally use now is white screen, makes with calico usually.Its luminance factor is between 0.5 to 1, and brightness is low.Thereby project effect is not good, and especially effect is relatively poor when projection wide-screen film and three-dimensional film.Improve brightness, must increase the electric current of projector.
In order to address this problem, developed the screen of a kind of raster grating formula plating recently.Its surface is to be formed by a plurality of small-sized concave surface proper alignment.The luminance factor of this screen between 2.5 to 3.37, the brightness height of more common calico screen.But the surface of this screen is small-sized concave surface arrangement to form, and the concave surface light reflex is real focus; Horizontal luminous intensity distribution angle is little; Processing technology requires high, and surface smoothness is difficult for meeting the demands.Thereby reflective inhomogeneous, the projected picture light and shade differs, and projection light is had the attenuation effect, makes movie theatre left side spectators see when picture and the right spectators see left side screen picture in the screen of the right weak effect.
The purpose of this utility model is that a kind of improved plating screen will be provided, and its surface is to be formed by a plurality of equal-sized small-sized convex surface proper alignment, and this screen has changed above-mentioned weak point.
The utility model is achieved in that Corvic is coated on the plain cloth (1) equably, 0.5～0.8 millimeter of the thickness of coating (2), make Polyvinylchloride---the cloth composite bed, this composite bed pushes through rolling equipment, coat side forms a plurality of equal-sized small-sized convex surfaces, very regular is arranging, and the geometric configuration of convex surface is the part of sphere, and its radius is between 1.5～2.5 millimeters.Composite bed after will pushing again plates the coat of metal (3) equably.
The screen of this microballon raster pattern plating is the principle that directional light is dispersed according to convex lens, when projection light shines directly in the screen, form the even and bright reflective spot of reflection on each small-sized convex surface microballon, whole projected picture glistening intensity height, luminance factor reaches 3.47, horizontal luminous intensity distribution angle is greater than 56 °, and is reflective even.Thereby movie theatre both sides spectators watch the projected picture effect in the screen the same substantially with the front.This screen not only is suitable for film (comprising wide-screen film and three-dimensional film) projection, and is applicable to magic lantern, TV and teaching projection.It is effective to put shadow, saves energy.
Fig. 1 is a partial schematic diagram of the present utility model.
Fig. 2 is a partial cutaway schematic of the present utility model.
Claims (2)
1, a kind of screen of being made up of plain cloth (1), Corvic coating (2) and the coat of metal (3) is characterized in that the screen surface is to be formed by a plurality of small-sized convex surface proper alignment.
2, screen according to claim 1, the geometric configuration of small-sized convex surface are the part of sphere, 1.5～2.5 millimeters of spherical radius.
