Present States of R&D for Low Power Consumption Display : Reflective type LCD

Abstract

Among many display technologies, one of the most promising approaches for the low power consumption electronic display will be the reflective type liquid crystal display (RLCD). However, there are still technological problems unsolved for the practical use of RLCD. The most important one is how to achieve enough brightness. In this review paper, many different approaches toward to this target will be discussed. Many of the results obtained from ASET project will be referred. Especially, the stacked three layered structure, HPDLC scheme, the directive reflector devices and image-memory LCDs are emphasized because of their high potentialities.
