Maximization of an Electric Field Penetrating an Optically Isotropic Phase Liquid Crystal for Low Operating Voltage Display

Liquid crystal displays (LCDs) correlated with polymer-stabilized optically isotropic state LC mixtures show relatively low light efficiency and very high operating voltage when the device is structured by interdigitated electrodes which generate in-plane electric fields. This is because the horizon...

Description
Summary:Liquid crystal displays (LCDs) correlated with polymer-stabilized optically isotropic state LC mixtures show relatively low light efficiency and very high operating voltage when the device is structured by interdigitated electrodes which generate in-plane electric fields. This is because the horizontal field intensity is not strong enough and half of the field is wasted by penetrating the substrate and the Kerr constant of the mixture is not high enough. We propose an electrode structure which can absolutely diminish the operating voltage while keeping the transmittance by generating in-plane electric fields penetrating the LC layer twice stronger than that of the conventional one.
