It’s been known for a long-time that displays are energy hogs and given that battery life is the most problematic issue for mobile computing, someone needs to find a way to improve it. Unipixel is a company who claims to have nailed it down.
A typical LCD display has 15 layers or so. Each of these layer help control how the light emitted from the back of the screen will been seen by the user. Each layer also absorbs a portion of the light, which is compensated by sending more light, which consumes more energy.
Unipixel reduces the number of layers down to 2, thus also reducing the energy required to light a pixel. The savings are so substantial that I could double the battery life of a phone, they say. We have yet to see it in action, but check it out here by watching the animation.
