Coatings are provided for outdoor signage and indoor LED screens for the same purpose. To reduce the glare of the light source reflected on it. The same technology is used for coating reading glasses too, when the light hits the reading lens, both in front and the back and bounces off it, enveloping the wearer’s eyes in a bright glare. Coming back to outdoor signage and home/office LED screens, this glare can cause harm to the eyes. Tired eyes syndrome results from being exposed to reflected glare from a light source beaming on the computer screen.

What is the solution?

Anti-glare coatings solve this problem effectively. These are polycarbonate sheets that are pasted on the screens. These sheets have tiny particles spread out on the surface, making it uneven acrylic diffuser sheet for led. When light hits this, the particles cause a diffusion of the light because the rays are reflected at different angles. This reduces the effect of bright sunlight and improves the readability of outdoor signage displays that are digital and perforce require LED screens.

Anti-glare and anti-reflective coatings

There is a coating called the anti-reflective. Anti-reflective and anti-glare are used interchangeably as they serve the same purpose – deflecting the reflected rays of the sun or light source away from the viewer’s eyes. However, the treatment accorded to the rays of light that fall on the reflective surface are somewhat different. With their respective coatings, the light rays behave differently in both the cases. The resulting diffusion is scattered in the anti-glare coating, while the reflected rays are organized away from the viewer’s eyes in anti-reflective coatings. Anti-reflective coatings are a series of optical coatings which bend the reflected rays, reducing the overall reflection much more effectively than anti-glare.
