초록
The voltage holding ratio (VHR) and Residual DC property in the in-plane switching (IPS) cell was studied Several IPS cells which have different concentrations of cynao liquid crystals (LCs) and different resistivities of fluorine LCs were fabricated VHR and residual DC voltage in the IPS cells using the capacitance-voltage (C-V) hysteresis method was measured. We found that the VHR of the IPS cell was decreasing with increasing concentration of cyano LC. The residual DC voltage of the IPS cell was decreasing with increasing concentration of cyano LCs. We suggest that the high polarity of cyano LC helps reducing the residual DC voltage.
