Everything You Need to Know About ALR Projector Screen Paint

Choosing the right ambient light rejecting projector screen paint according to your setup can be tricky, provided the plethora of options available. A good understanding of how these paints work will stir you in the right direction and help navigate the world of ALR projector screen paints with more confidence.

Higher image quality projected on ambient light rejecting paint

What is ambient light rejecting projector screen paint?

ALR projector screen paint, is a specialised type of screen paint designed to deliver bright pictures with maximum pixel definition even in environments with some ambient light.

These paints are formulated in a way that makes them capable of selectively reflecting projector light to the audience while scattering the ambient lights hitting the screen from the sides. This helps eliminate washed-out effects, even in brighter setups.

Ambient light rejecting projector screen paint is an ideal projection screen solution for living rooms with some ambient light. They often make the top choice for home theatres with controlled lighting, plus gaming and conference rooms with moderate ambient light.

However, ALR paint isn’t suitable for highly sunlit rooms or rooms with multiple light sources. If your room enjoys direct sunlight, and has large windows without effective curtains or blinds, the paint will struggle to diminish the impact of the excess light.

How does ALR projector screen paint differ from standard projector screens?

Surface reflection is primarily of two types— diffuse reflection and specular reflection.

When light hits an uneven surface, like a fabric, paper, or the walls, they are scattered off in different directions without any order. It is called diffuse reflection.

When light falls on an even surface, like a mirror, they bounce off in a systematic way and it is called specular reflection. In specular reflection, the angle of incidence will always equal the angle of reflection at which the light bounces off.

Diffuse reflection occurs with many standard fabric projector screens. As all light rays are treated equally and reflected at all angles, the ambient light in the room dulls the light coming from the projector.

However, all projector screens might not be pure diffuse reflectors. Some screens might be designed to reflect light more at a particular angle than others. This results in higher brightness or gain within a specific viewing angle.

Ambient light rejecting paints, on the other hand, often use a combination of different technologies to selectively reflect the projector light to the audience while absorbing or scattering out the ambient light.

Our ambient light rejection projector screen paint takes it a step forward by leveraging advanced selective light rejection technology. It uses a uniquely formulated, multi-layered paint-based coating system to deliver brighter, more vibrant images.

After application, the paint’s transparent matting system covers the surface, which effectively refracts stray light towards the screen, where a portion is then absorbed by the unique pigment system. This multi-layered approach significantly reduces the amount of scattered light that would otherwise diminish image quality.

Considerations for using ambient light rejecting paint in different setups

Ambient light rejecting paints are designed to enhance image quality, but ideal conditions always play a crucial role. Before you choose a product, evaluate your room’s lighting and projector setup. For optimal performance, consider the following:

Light conditions

  • ALR paint works best in rooms with low to moderate ambient light. It’s designed to combat light from windows, lamps, or other moderately bright sources. Our ALR paint works efficiently in dark and light controlled rooms as well.
  • Avoid direct sunlight and extremely bright environments, as excessive light can still impact image quality. Use curtains, blinds, or shades to block sunlight during projection. Controlling light ensures that the ALR paint can effectively manage and reflect the projected light without interference from external light sources.

Projector specifications

  • Every ALR projector screen paint comes with specifications that should match your projector. Consider the type of projector the paint is designed for to make the right choice. For example, our Ambient Light Rejecting Projector Screen Paint works with standard, ultra-short throw, long throw, as well as laser projectors.
  • The minimum recommended lumen value for a particular ALR projection screen paint is another aspect you can’t miss. The lumen value of a projector indicates its brightness. Higher lumens ensure better visibility in rooms with ambient light, making it crucial to match this with the ALR paint specifications. Our ALR paint has a minimum recommended lumen value of 3,000 lumens.
  • Always ensure that the projector light hits the screen directly while minimising side light. Position your projector and screen to align with the intended light path.
