Projection screen can be classified according to different situations, general materials can be divided into white plastic, gray plastic, metal, glass fiber, glass beads these five kinds, respectively corresponding to different use of the scene to create a different visual effect, so as an ordinary consumer which material is the best?

The difference between the curtain and the white wall

1. Poor reflection performance of white wall


Projection screen, with special optical materials to improve its reflection performance, such as increase in gain, expand the Angle of view, improve resolution, enhance contrast, enhance color reduction and so on.

White walls don't have these properties at all, and the resulting images are not as good as those on the screen in terms of brightness, contrast, and color saturation. The sharpness of the image is also affected by the texture of the wall.

2. White walls are easy to be polluted

White wall used for a long time, pollution is inevitable, even discoloration. And the curtain can be folded up for protection after use, also can be regularly clean maintenance.

3. White wall without black border

Do not underestimate the black border, recall that the projection screen, cinema screen, flat screen TV, are all designed with a black border, most laptops, LCD is the same. It can improve the attention and contrast of the picture, reduce the surrounding influence, and improve the visual quality of the picture itself.

Conclusion: white wall can not replace the projection screen.

The material of the curtain

The curtain material is divided into white plastic curtain, gray plastic curtain, metal curtain, glass fiber curtain, glass bead curtain and so on.

Glass fiber curtain and white plastic curtain will be enhanced in the projector effect on the check is not much, in the case of low temperature more easy to curl the curtain.

Metal screens are mainly used for 3D and anti-light screens.

Conclusion: it is ok to project a picture onto a white wall, which is more convenient in some specific informal situations, but the actual effect can only be described as poor.

You know, the projector is only 50 percent of the picture display work, that is, photoelectric conversion; The remaining 50% of the work, the success or failure of the image presentation, is done by the projection screen. So the curtain plays a very important role in the overall effect of the phenomenon.

Home users purchase projection is nothing more than to sell high-quality viewing experience, improve the quality of life. So I suggest to have the condition had better be equipped with an appropriate good curtain, its to the projection enhancement effect is still very obvious, when choosing must be mainly combined with the actual situation, avoid blindly big.
