摘要: The electro-optical responses of the in-plane switching (IPS) dual-frequency liquid crystal (LC) cell operated with the amplitude-modulation method and the frequency-modulation method were investigated. The obtained results reveal that the electric torque exerted to the LCs and the strong anchoring energy produced from the rubbed polyimide dominate the reorientation of the LCs. With the frequency-modulation method, the generated electric torque combined with the strong surface anchoring energy give the cell a very short fall time, which is independent of the applied frequency. A new waveform composed of the amplitude modulation and the frequency modulation of the supplied voltage-pulse to achieve a fast responding IPS LC cell is proposed. The obtained response time is much less than that of the conventional amplitude-modulation method.
