概要

Liquid crystals which have spontaneous polarization exhibit sharp decline of holding voltage when they are driven by TFT and their response time is longer than charging time. The reduction of effective applied voltage causes low contrast, so it is an important problem in designing LCDs. This phenomenon is explained by a simple model calculation considering the dynamics of outer and inner charge of the LC cell. On a certain condition, long period oscillation of holding voltage is observed. This anomalous unstable behavior depends on temperature, charging time, storage capacitance and applied voltage.
