Liquid crystal display device having an alternating common electrode voltage |
摘要 |
An active-matrix liquid crystal display device applies a voltage modulated with a high-frequency AC voltage to a common electrode disposed on a substrate which confronts a substrate having a plurality of thin-film transistors as switching elements for pixel electrodes. The modulated voltage applied to the common electrode is effective to reduce the phenomenon of a residual image retained for a long period of time; thereby improving the quality of displayed images.
