The Challenge

For display devices such as mobile phones and laptops, sunlight readability is essential. Sunlight readability refers to the discernibility of a display in high ambient light conditions, and is strongly correlated to surface reflection. Currently, many displays have poor sunlight readability due to high rates of light reflection, requiring boosted display luminance and, in turn, more energy.

Innovation Details

The film is made of a molded, UV-curable resin. The surface of the film contains uniform nanostructures shaped like cones, each about 100 nanometers in diameter (about one one-thousandth of the width of a human hair). These protuberances are clustered so closely together that incoming light cannot differentiate between air and the surface of the film, thus passing into the material with very little reflection. The film exhibits a surface reflec­tion of just 0.23%, much lower than the average reflection rate of current displays, 4.4%. The antireflection film also found an application in solar cell efficiency, significantly increasing light absorption rates of photovoltaics.

Biomimicry Story

Most moths are nocturnal creatures and fly at night to avoid being spotted by predators. The eyes of a moth are unique in that they are anti-reflective, absorbing incoming light and minimizing the amount of reflection to keep the creature undetected. This anti-reflective property can be attributed to the cone-like nanostructures which are clustered on the corneal lens of the eye, reducing light reflection by creating a refractive index gradient between the air-lens interface.
