Abstract

Voltage holding ratio (VHR) and residual DC phenomena for the in-plane switching (IPS)-liquid crystal display (LCD) on a rubbed polyimide (PI) surface were investigated. It was found that the VHR of the IPS-LCDs on the rubbed PI layer increased with increasing concentration of cyano LC and specific resistivity of fluorine LCs. Also, the residual DC voltage in the IPS-LCD by voltage-transmittance (V-T) hysteresis method decreased with increasing cyano concentration of LCs. The residual DC voltage of the IPS-LCD can be improved by high polarity of LCs. Finally, the new residual DC voltage measurement of the IPS-LCDs by light minimum/maximum method is proposed.
