The classification of projector screens is diversified. Generally, it can be divided into white plastic, metal, glass fiber and glass beads according to different materials. It can be arbitrarily selected according to the place of use. So what kind of material is good for household projectors?
1.Matt white / Matt grey
Matt white directly uses coarse white fabric, no surface treatment, and the surface is touched by hand to feel rich texture.
It is characterized by the performance of the projector, the original original performance, no modification, low gain, large viewing angle and natural color.
Matt grey is often referred to as a “high-contrast screen” that absorbs more ambient light than a white screen, which allows the black level on the screen to be maintained.
It features high brightness, high contrast, good color reproduction, clear imaging, large field of view, soft light, long-term viewing and fatigue, and scrubbing.
2.Metal
The metal curtain is a hard curtain in which a finely packed metal molecule is coated on the outer surface of the resin sheet to form a honeycomb array, and the disturbing light waves incident from the periphery oscillate, attenuate and are absorbed as they pass through the array.
It is characterized by good flatness, not easy to damage, long service life, high gain, high brightness of the picture, especially when displaying dynamic video or picture, strong sense of layering and depth makes the image vivid and lifelike, especially suitable for movies. , 3D animation and game display.
3.Glass Fiber
The glass fiber screen is superior to the original US. Divided into white glass fiber and gray glass fiber. The base fabric is woven from glass thread, and the surface layer is coated with PVC material with special projection effect. Thanks to the support of the fiberglass backing, there is no need to level and the natural stretch will be straight.
On the basis of retaining the advantages of white plastic screen, the glass fiber screen compensates and adds the following differences: 1. Moisture proof and mildew proof; 2. Good for cleaning; 3. Temperature difference and climate change can also be kept flat. Straight; 4, high gain and high contrast.
4.Glass beaded
The coating of the optical crystal glass sphere is added to the surface, and the surface of the glass ball is touched by hand, and the fine glass beads can be felt to fall off.
The feature is that the picture has a clear sense of focus and vitality, with high gain and small viewing angle. The biggest feature is “light return”, that is, the reflected light returns in the direction of the incident light, which is also a reason for the high gain, which has a certain “collecting” effect on the light.
