Enhanced contrast ratio of homogeneously aligned liquid crystal displays by controlling surface anchoring strength

摘要：

The dark state of homogeneously aligned liquid crystal displays (LCDs) associated with in-plane switching of LC director depends on their molecular ordering. We propose a new approach to reduce the light leakage in the dark state of homogeneously aligned LCDs. A very small amount of reactive mesogen (RM) is mixed with the LC material and polymerized at room temperature and also at low temperature (-20 °C) to strengthen surface anchoring energy. The contrast ratio of the low temperature cured cell is improved about 50 ％ than that of the pure LC cell and the room temperature cured RM-mixed LC cell due to enhanced order parameter.
