Previously, touchscreen manufacturers have tried to reduce glare on their displays by using layers of different materials with varying refraction indexes. And working together, they help minimise the reflection of external light sources into your eyes. But Sony's new approach involves a special film that was inspired by a moth's eyes. Across its surface is a pattern of microscopic concave and convex structures that serve to evenly bounce light away from the user, reducing glare. Apparently, the approach works on an even wider range of wavelengths than the anti-reflective coatings currently in use.
The improvement means less squinting for users or awkwardly angling their device away from a light source. And since increasing the display's brightness is one way to reduce glare in current devices, it will also let users increase their battery life by turning down their displays. Next step: actually getting this stuff from being just a fancy trade show tech demo to actually on devices.
