Abstract

Liquid crystals have been extensively employed in photonic devices, especially in current flat-panel displays. Demands on high-quality electro-optical performance of liquid-crystal displays have continued to impel delicate molecular designs, chemical syntheses, as well as advanced cell-manufacturing processes, leading to a reduced dc offset and faster intrinsic response in the devices. Here, a novel approach toward the reduction of the residual dc and response time is reported based on carbon-nanotube doping. It is demonstrated that a minute amount of carbon nanotubes as a dopant can suppress the unwanted ion effect, invariably lower the rotational viscosity, and modify other physical properties of the liquid crystals, giving the approach an opportunity in display applications.
