Projection Screen Films
Projection screen film series for different applications of projection screens like fixed frame, motorized, portable,..etc. We have hi-end materials for ALR/4K/3D home theatre and 5meter width seamless screen films. Different projection screen films handle different applications and environments, their effectiveness depending on several factors, including the resolution of the media used, the lighting and acoustic conditions and the viewing angle of the audience. There are some key features for projection screen materials:
Flatness is the core value of the projection screen films. We import 5meter width stretchless calendering machine from Italy to imrpove the flatness of the pvc film. The film produced by this machine is from the real width without extending. So the material has top grade consistant thickness, low shrinkage and dimensional stablity. We also have advanced film to film, film to base fabric lamination machines opearted by skilled engineers to ensure the full product line has outstanding flatness.
Gain is a measurement describing the light reflectivity of a film, when the measurement is taken for light targeted and reflected perpendicular to the screen. A gain greater than 1.0 means the projection screen material increases the brightness of the projected image, while a gain less than 1.0 means the image produced is not as bright. This aspect is affected by the material colour, suface treatment and embossing pattern. We have different types of embossing rollers with delicate patterns to create accurate and uniformed glossy rate for different applicaitons of the projection screen films.
Viewing angle is a measurement describing the maximum angle from the center of the screen at which you can still see a quality image. Some projection screen films reflect most of the light perpendicularly to the screen, sending much less to the sides. This makes the screen appear much darker and more distorted if the viewers are not in the optimal viewing angle of the screen. Unfortunately, high-gain films tend to have a lower viewing angle.
The color of the projection screen films greatly influences the contrast of your final projected image. White screens are the industry standard due to brightness, while gray screens are better at handling darker tones.
