Description
Technical field
The utility model relates to shadow casting technique field, particularly relates to a kind of reflection type projection screen of MULTILAYER COMPOSITE.
Background technology
According to the difference of projection pattern, projection screen is divided into two kinds of front projection screen (reflective) and rear projection screens (transmission-type).The quality of screen quality is directly connected to the quality of imaging picture, and the projection screen that therefore obtains outstanding quality is the target that projection field is pursued always.Along with the development of shadow casting technique, projection screen is also in constantly exploitation innovation.The utility model relates generally to front projection screen.
The important parameter of weighing Screen Technology comprises gain, noise immunity and visual angle etc.Gain is to expect intrinsic reflection characteristic with numeral curtain.The in the situation that, incident flux certain at incident angle of light being constant, the ratio of the brightness in screen a direction under brightness and perfect condition, is called the party's luminance factor upwards, maximal value is wherein called to the gain of screen.Conventionally the gain of the white wall of tarnish is decided to be to 1.Noise immunity refers to the antijamming capability of screen to surround lighting.In bright environment for use (as hall, meeting room, market etc.), the image that human eye is seen is to be formed by projector's projection light, surround lighting and screen basic unit Colored light mixing, and wherein surround lighting is particularly evident on the impact of image effect.Surround lighting is stronger, and the contrast of picture is lower.Just because of this, can resist surround lighting to become real high-end projection screen and the most obvious watershed divide of low side projection screen.Screen reflection is in all directions different, in the horizontal direction from screen center more away from, brightness is lower, the viewing angle in the time that brightness drops to 50%, is defined as visual angle.What visual angle was reflected is the homogeneity of screen reflection ray in all directions, is embodied in the uniformity coefficient of screen simultaneously.In general, the gain of projection screen and visual angle are conflicting, and in the situation that other condition is constant, more the visual angle of giant-screen will be less in the gain of screen, otherwise more the gain of giant-screen will be less at the visual angle of screen.
Common front projection screen comprises: mould in vain curtain, glass bead screen and metal curtain etc.But the noise immunity of these screens is all lower, and can only between gain and visual angle, carries out balance and can not improve it simultaneously.Therefore, a kind of high-gain, high noise immunity, the screen at wide visual angle is most important to the development of projection field.
Unresolved above-mentioned technical matters, the reflection type projection screen of a kind of MULTILAYER COMPOSITE that the utility model provides.
