Light guide film – what exactly is this product? Those unfamiliar with the industry will surely be utterly baffled: what film? What light film? What on earth is a light guide film?
As the name suggests, ‘light guide film’ literally means a film that can guide light. The English term is a direct translation: Light Guide Film.
The operating principle of light guide films is relatively straightforward. Primarily, it utilises the reflection and refraction of light. Through specialised optical software design, microstructures are processed onto thin optical fibre films. This disrupts the conditions for total internal reflection, allowing light beams to propagate from the medium at the required angle and density, thereby achieving uniform illumination.
Light guide films are intimately connected with our daily lives, finding applications in: mobile phone backlight panels, tablet computer logos, remote controls, and keypads. Now that we've explained it, does it all suddenly come together more vividly in your mind?
