Twist angle effects on the dynamic response of in-plane-switching liquid   crystal displays
  Twist angle effect on the response time of in-plane-switching liquid crystal displays are analyzed. We propose a device configuration whose top and bottom boundary liquid crystal layers are symmetric to each other with respect to the electric field direction. The analytical results of this device configuration indicate that the response time is improved at least 4X faster than that of a conventional in-plane-switching twisted-nematic mode and normal in-plane-switching mode.
