Making Anti-Glare and Anti-Reflective Displays

Anyone who has tried to look at a phone, tablet, or laptop screen in Sunlight knows just how frustrating the glare and reflections of the screen can be. This makes it rather unsurprising that so many products exist to counter the problems, but some do not work well with glass. Researchers at the Institute of Photonic Sciences and Corning Incorporated though have developed a new method to make glass surfaces anti-glare, anti-reflective, and even hydrophobic.

Today you can go out and get anti-glare filters and films for your devices, and some have nanostructures on top of them, to add anti-reflective properties. These structures do not work well on glass, so the researchers worked on the glass directly. By roughening the surface of glass at a very fine scale, it can be made anti-glare without sacrificing transparency. Etching in nano-sized teeth makes it anti-reflective, and as it turns out, the resulting surface features made the glass water repellent, like a lotus leaf.

This method to affect the properties of the glass is inexpensive and can be scaled up for industry use. Before that will happen though, more research needs to be done, in part to determine how well the features endure touchscreen use.
