Abstract

In this research, the image-sticking property in the in-plane switching (IPS)-liquid crystal display (LCD) with residual DC voltage on a rubbed polyimide (PI) layer was studied. Voltage holding ratio (VHR) and residual DC voltage by capacitance-voltage hysteresis method in the IPS-LCDs was measured. It was found that the VHR increased with increasing specific resistivity of fluorine LCs. The residual DC voltage decreased with increasing concentration of cyano LCs and decreasing with increasing specific resistivity of fluorine LCs. Consequently, the residual DC voltage can be decreased by high polarity of cyano LC.
