What is a light blocking projection screen?

Écran de projection anti lumière

An anti-light projection screen features special optical technology consisting of an integrated lenticular screen with a black grid structure, the black parts of which absorb ambient light while the white elements reflect the projected light directly towards the viewer. This optical technology allows anti-light displays to be used in fully lit indoor environments, creating the clearest, truest images of the highest quality.

The material used absorbs up to 95% of incoming light from video projectors while canceling out washout from ambient lighting, especially large overhead lights. The contrast is up to 100 times greater than that of a simple non-reflective white or gray screen.

How anti-light screens work

  1. Absorbing or diffusing materials : Light shields are made from special materials designed to absorb or diffuse ambient light rather than reflecting it. These materials may include absorbent coatings, diffusing layers, or fabrics specifically designed to reduce light reflections.

  2. Special optical coatings : Some light-blocking screens have special optical coatings that are designed to absorb or filter specific wavelengths of light while still allowing the projector to produce a clear, bright image. These coatings are often designed to optimize contrast and color fidelity.

  3. Micro-Texture Structures : Some anti-light shields use micro-texture structures on their surface to disperse incident light more evenly, reducing hot spots and glare. These textures may be invisible to the naked eye but play a crucial role in the overall performance of the screen.

  4. Restricted viewing angles : Some light-blocking screens are designed to have restricted viewing angles, meaning they are most effective when the viewer is directly in front of the screen. This reduces the amount of light scattered in other directions and thus improves the contrast of the image.

Advantages of anti-light screens

Anti-light screens offer several advantages that significantly improve the viewing experience:

  1. Increased contrast : By reducing unwanted light reflections, anti-light screens provide better contrast between dark and light areas of the projected image, providing a more dynamic and immersive image.

  2. Better readability : By eliminating distractions caused by ambient light, these displays improve the readability of projected content, whether text, graphics or video, even in bright environments.

  3. Color Accuracy : By reducing light interference, anti-light shields preserve color fidelity, allowing viewers to enjoy accurate reproduction of hues and shades.

  4. Versatility : Anti-light screens are suitable for a variety of environments, from home theaters to conference rooms to commercial installations, providing a versatile solution for different viewing needs.

  5. Reduced eye strain : By providing a sharper image that is less prone to glare, these displays help reduce eye strain, allowing viewers to enjoy long periods of viewing comfortably.

  6. Enhanced Privacy : By limiting light diffusion beyond the screen, anti-light shields also provide some privacy by reducing image visibility from the sides, which is advantageous in applications requiring a certain discretion.

Do you need an ALR display?

There are certainly many types of screens you can choose from and it can be confusing.

However, to quickly answer the question posed at the beginning of this paragraph, yes, in many cases you should invest in an ALR display to improve your viewing experience. Traditional or basic screens fail to reject or bounce ambient light. And while this won't be a problem in a dark room, if you have more light coming in, your image will appear washed out and discolored on regular screens. If you know you'll be watching content in a room that may be bright at times, we recommend opting for an ALR screen. But the proof is real experience. Since regular monitors are very affordable, you can try one out and if you're happy with it, stick with it. You can always get an ALR screen later to improve the display if necessary.


In a modern environment where technology plays a central role, using a smart projector with an anti-light projection screen can transform your space into an immersive cinema room, providing an unparalleled viewing experience.
