What is the function of the projector curtain?

Curtain is an accessory product of projector, but it is not a necessity. Without a curtain, you can see it on the white wall, but the projection effect will be slightly worse. If the projection quality is not high or the projector quality is not very good, it is ok not to buy it, but it is better to buy it if possible, because the projection curtain helps to obtain brightness, enhance contrast and improve picture clarity. Let's look at the role of the projection curtain. 1. Is it necessary to buy a projection curtain?

With the improvement of living standards, more and more people buy intelligent projector equipment. As a supporting product of projector, is projection curtain necessary? Is it necessary to project a curtain?

In fact, the curtain is the product of different materials and coating processes, and the effect is definitely different from that of ordinary white walls, but the difference is not so great, because the brightness and resolution of ordinary household projectors are not very high, even if they are matched with expensive high-quality curtains, it is a waste. As for ordinary curtains, if there is no particularly good coating technology, it is not much better than white walls.

However, if it is a top-class projector, the projection effect is very good, or you should buy a matching projection curtain, and the display effect will be better. After all, if projected on the curtain, the gain effect will be better, the contrast will be higher, and the fineness of the picture will also have a certain gain.

So to sum up, if conditions permit, it is better to buy a projection curtain, and the projection effect is much better; If the quality of the projector is not very good, I have no special requirements for the projection effect, and it is ok to project directly on the white wall without buying a curtain.

2. What is the function of the projector curtain?

When using the projector, many friends will ignore the role of the projection curtain, thinking that the curtain is a dispensable product, otherwise it will be the same when projected on the white wall, but in fact, the projection curtain plays a great role, which mainly includes:

1, brightness gain

Gain refers to the ratio of the brightness reflected by the projection screen to the brightness reflected by the white wall when the projector and the external ambient light are fixed. Theoretically, a high-gain projection screen can provide a brighter picture, and you can see the picture clearly even if the external ambient light is large.

2. Enhance contrast

The projection cloth with strong contrast can reduce the interference of ambient light. General projection cloth can enhance contrast by reducing emissivity or directional reflection, and some high-grade projection curtains can deal with the reflection and absorption laws of light with different incident angles through precise optical structure design, thus enhancing contrast.

3, improve the picture clarity

Both curtain and projector have resolution, and the size of the smallest optical structure on the curtain determines the resolution of the curtain. Only when the resolution is obviously higher than the projector, the projection system can display a clear picture, and the high-resolution curtain with the high-resolution projector naturally has a better projection effect.
