Why is the light shield gray?

Because gray helps to improve the position in a non-black environment. So the reflective curtain is gray. Gray helps to improve the position in non-black environment, that is, it improves the contrast in disguise, and also improves the color saturation and reduction. It is also very important that the light screen can resist the interference caused by ambient light, so that the picture is no longer gloomy when there is light, and the viewing effect is obviously improved.

Introduction of light curtain

Anti-light curtain uses physical structure or optical coating to achieve anti-light effect. Compared with the white screen, the screen black position of the anti-light screen is better, and the picture contrast is higher, but the brightness gain is slightly weaker than that of the white screen, generally at 0:08-0:09. In terms of screen structure, hard screen, such as nuefeld screen, is the main choice for light screen, because the optical structure determines that it cannot appear on soft screen.

At present, the real light-proof curtain absorbs light, and its brightness is not as good as that of a white wall in a completely black environment, so the light-proof curtain is not suitable for household projectors with low lumens, such as miniature household projectors, household projectors with high lumens, and it is suitable for use with more than 2000 lumens, and the effect is very good.

To put it bluntly, the all-black environment can not only reduce lumens, but also resist the better light-resistant curtain of ambient light. With the ultra-narrow metal frame, it is similar to a TV set, which is elegant and atmospheric. If you want to change the TV or often watch movies in a non-black state, then the light screen is very important.
