66.3: Design of Color Backlight for High Efficiency Display using Optical Waveguide Gratings

“…Local dimming is an effective way to saving the power consumption of a TFT-LCD from system side due to its synchronized distinguishing with displaying image. [2] Low loss polymer optical waveguides with tiny dimension has been reported in recent decades [3,14,15], which are suitable for light guide plates in display backlights.…”
