LCD Filter Could Make Screens 400 Percent More Energy Efficient
 

A new color filter developed by researchers at the University of Michigan could enhance LCD efficiency by 400 percent.

Professor L. Jay Guo and his team have created an optical film that both polarizes and colors the light that passes through an LCD, which replaces the multiple layers of optical devices that traditionally played the same role. With the use of these conventional layers, an LCD would only emit eight percent of the light produced by its backlight. With the newly developed film, 36 percent of light is emitted, which is an increase that enhances overall LCD efficiency.
