A Simple Filter Could Make LCDs More Efficient

A new type of color filter could significantly increase the energy efficiency of liquid-crystal displays (LCDs), which dominate the market in everything from televisions to cell phones.

The best LCDs today only emit about 8 percent of the light produced by their backlights. This means that they drain batteries in portable electronics and ramp up electricity bills in homes (the California Energy Commission estimates that televisions consume 10 percent of the electricity in homes).

This sounds like an innovation that will actually find its way into production. 400% more efficient, cheaper and easy to build…I’d say that would be very attractive to the industry.
