Abstract

Two different configurations of transflective liquid crystal displays (LCDs) using multi-domain method will be presented. One is composed of hybrid-aligned nematic mode in the reflective region and parallel-rubbed vertically aligned mode in the transmissive region. In order to make the reflective and transmissive regions in the same pixel independent, an Ar⁺ ion-beam alignment method is used. The other multi-domain transflective LCD, where vertically aligned mode is applied, has patterned metal electrodes on one substrate. In this mode, the device can be designed with single driving circuit and single cell gap. These transflective LCDs show excellent performance in reflectance and transmittance characteristics, viewing angle property, and contrast ratio.
