Researchers Discover the Future of Digital Displays

Posted September 24, 2014 12:00 AM by Engineering360 eNewsletter

Imagine an ultra high-resolution display built directly into your contact lenses! That's exactly what researchers have imagined, and potentially created, by adapting a material currently used to store data on DVDs. The technology relies on phase-change materials that switch colors when their temperature changes. The discovery could lead to thinner, lighter, higher resolution displays and lower power consumption than today's technologies provide. By mounting the material on flexible or transparent surfaces, developers could create UHDs on contact lenses, car windshields, and virtually any flexible transparent surface imaginable.

Anyone who wears glasses or contact lenses knows that the lens surface itself is out of focus. Researchers have used the same 'wearable display' phrase for years and the best anyone has done has been devices like google glasses.

Until materials are developed and are made cheap that work in the visible spectrum and have negative indices of refraction, 'contact lens' displays will remain a thing of the marketing guys, not the engineers.
