Cinemas have been developing more and more in recent years. The biggest activity in shopping malls is now watching movies besides eating. Shopping is just an additional leisure. Many young people go to movies with the environment and different sound effects. Cable TV is becoming less and less, and web dramas and movies have become the mainstream of leisure after work.

Some families pursuing high-quality images will choose anti-light screens and projectors to build home theaters. So what is the magic of anti-light screens? Today we will decrypt it together!
The biggest advantage of anti-light curtain:
The biggest advantage of anti-light curtains is that they can enhance the image effect of the projection under the interference of light. It can be used in an environment where the curtains are opened during the day and the lights are turned on at night, allowing people to bid farewell to the “black room”.
The feature of anti-light curtain is: through anti-light, filtering, and absorbing ambient light, it can achieve the effect of enhancing picture contrast, brightness level, color brightness, hue and saturation.
Its core: absorbs ambient light and improves picture contrast
The anti-light curtain realizes anti-light through optical coating and physical structure. In addition to absorbing the surrounding ambient light, it can also control the reflection of the incident light from the projector to the viewing angle area where the human eye is located, so as to minimize the projected light scattered into the space. In this way, the utilization efficiency of light energy will be greatly improved, the eyes will receive more projection light/energy, the interference of ambient light will be reduced, and the color, brightness and contrast will be effectively improved. This is why the anti-light curtain effect is much better than The reason for the ordinary diffuse reflection screen.
The reason why the anti-light curtain improves the brightness is not because the brightness of the laser TV is invariant. 3000 lumens is 3000 lumens. There is no external method to increase this value. More importantly, many friends have overlooked the fact that it is the contrast and color, not the brightness, that determine the quality of the picture. The reason why everyone pays much attention to brightness is that brightness is an important factor in determining the contrast of the picture.
