Abstract

We have proposed a novel optical design technique of light-guide plates(LGPs) which can able to improve the optical efficiency of transflective LCDs. The basic concepts of our design technique are that we make the groove-pattern of LGP pixels resemble the pixel-array-pattern of transflective LCDs in shape and size and make the surface of the groove scatter (front scattering). In simulated and measured results, we ensure that our design of LGP in backlight unit for transflective LCDs can improve the optical efficiency of LCDs.
