Driving method of a liquid crystal display device

摘要

In an active-matrix type liquid crystal display device, a dummy scanning line is provided at a higher position than the top of ordinary scanning liens in the case that a scanning operation is performed from the top of a display region to the bottom thereof. Alternatively, such a dummy scanning line is disposed at a lower position than the bottom of ordinary scanning lines where the scanning operation is performed from the bottom of the display region to the top thereof. Scanning pulses to turn on switching elements as well as compensation pulses are applied to the dummy scanning line as to the ordinary scanning lines to obtain a uniform brightness display on a screen of the active-matrix type liquid crystal display device.
