Fast Switching Surface-Polymer-Assisted Vertically Aligned Nematic Displays

摘要

We demonstrate fast switching surface-polymer-assisted vertically aligned (SPA-VA) liquid crystal displays (LCDs). The formation of polymer nano spikes at the both substrate surfaces as the alignment layers is achieved by liquid crystal (LC) directed polymerization of a small amount of a reactive monomer in vertically aligned liquid crystal. At appropriate concentration, the phase-separated polymer and facilitate formed nano-sized spikes. These polymer nano-spikes act as internal surface alignment layers and enable the fast switching of field-induced reorientation of liquid crystal molecules.
