Projection curtain from the material on the sub, mainly divided into the following eight types:
1, white plastic screen: gain 1.1, visual angle, 160 degrees, with good color reduction, wide angle, soft light, long time watch is not easy to fatigue, the advantages of long service life, suitable for household and commercial, the most widely used, the price is the most economical. Commercial projectors above 2000 lumens or home projectors over 1000 lumens are recommended for purchase. Also widely used in engineering projects, outdoor occasions, KTV and so on. Scrub.
2, glass bead curtain: gain 2.5~2.8, visual angle: 45 degrees, with high resolution, color reproduction is good, the advantages of clear imaging. Suitable for low lumen projectors, used to increase projection brightness. Commercial projectors, 2000 lumens less or home projectors, 1000 lumens below, LED projectors, it is recommended to buy. Can not be used outdoors, can not be cleaned, use for a long time will slowly yellowing, this is a normal glass bead curtain is like, not a quality problem.
3 HD, gray plastic scene: a gain of 1.1, more than 160 degree viewing angle, high brightness, high contrast, color reproduction is good, clear image, can support 108OP imaging projection, large view angle, soft light, watching for a long time without fatigue. Scrub.
4, metal curtain: gain 3.5, visual angle: 45 degrees, with high resolution, color reproduction is good, the advantages of clear image, generally used for engineering projects or low lumen projector, such as micro projector, projector 100 lumens. Scrub.
5, white soft screen: gain 1.1, visual angle > 160 degrees, with color restore good, large field of view, light soft, long time to watch, not fatigue, long service life advantages. The white soft curtain can be folded, folded and straightened, so that it is suitable for buyers who often go out to carry curtains, so it is easy to carry. Scrub.
6, HD: gain 1.2, white glass curtain, 160 degree viewing angle, high brightness, color reproduction is good, clear image, can support 108OP imaging projection, large view angle, soft light, long time to watch the screen surface is not easy to fatigue, uniform thickness, light weight, high screen surface flatness. Not affected by the temperature and curling, after special processing, the physical parameters of the screen surface quality stable, the most advanced beyond the existing white plastic screen surface. HD projector. Scrub.
7, HD glass gray screen: gain 0.9, more than 160 degrees of visual angle, high contrast, color reproduction is good, clear image, can support 108OP imaging projection, large view angle, soft light, long time to watch the screen surface is not easy to fatigue, uniform thickness, light weight, high screen surface roughness. Not affected by the temperature and curling, after special processing, the physical parameters of the screen surface quality stable, the most advanced beyond the existing gray plastic screen surface. HD projector. Scrub.
8, the rear projection screen: high transparent PVC special material (the silver screen, rear projection with polyethylene) light permeable strong, light transmission rate of 80% (domestic projection screen transmittance about 50%), for behind the projector projection, front viewing. Suitable for window display and some special places.
