How to choose the film cloth for projector? Which price is more suitable?

To choose the film cloth of the projector, that is, the curtain, you should understand the following knowledge.

First, the advantages of curtains

1 to improve the contrast. Although the physical contrast of its own image is fixed, a good curtain can further improve the contrast of the picture, which mainly depends on coating a layer of optical material on the surface of the curtain to improve the reflection ability.

2. Improve the brightness of the picture. Similarly, the projection curtain can also improve the brightness of the picture you see. For example, your projector is often used during the day, and you can choose gray fiberglass or metal, which will have better light resistance. However, the requirements of these two devices are relatively high brightness, which needs to reach 1900 cm or more to look darker.

3, the cleaning effect is better. The white wall at home always affects the projection effect. Usually, the curtains are put in wooden boxes, and even if they are fixed outside, they can be wiped regularly, which is always easier than painting the walls. Finally, because there is no border on the white wall, it will reduce our attention in the process of watching movies, while the curtain with border is easier to concentrate. In all fairness, in fact, the white wall is not unusable, and the projector is not often used.

Second, the curtain material

1, Bozhong road curtain, cheap, high brightness, high resolution, good light collection effect, suitable for projectors with low lumens to improve the projection brightness, but the disadvantage is that it is easy to reflect light during the day, and the picture will be whitened, and then the essence. In fact, it is the simplest coarse-grained fabric without surface treatment. It accurately reflects the performance of your projector, and the colors are relative.

2, gray plastic curtain, high contrast, the screen can absorb more ambient light, high brightness, high contrast imaging clear, long-term use of the eyes is not tired. Another commonly used material is fiberglass curtains. If it's ordinary home projector, I recommend this material most. It is woven with glass fiber and coated with a layer of PVC at the bottom. This material is moisture-proof and mildew-proof, and is also beneficial to cleaning. Moreover, it has long service life, naturally stretches and straightens, and does not need deliberate duckweed white glass fiber. Its cost performance is relatively high, which can increase the contrast of the picture, but the disadvantage is that the light resistance during the day is not strong.

3. The gray glass fiber curtain has better color reproduction, strong light resistance, and will not tire the eyes for a long time, and the projection effect is better than that of white, but this curtain requires higher parameters of the projector, which needs to reach 1900 lumens or more, otherwise the picture will be darker.

4, metal curtains, he is mostly based on imported aluminum foil, composite materials, synthetic resin materials, plus wood surface contrast, clarity, color reproduction, environmental protection, durability and other indicators can be full, and support 4K ultra-clear 3D imaging. ? The requirements for projectors are also higher. If the projector at home is no more than 2000 meters, just understand.
