Abstract
An active-matrix LCD device drives the LCD panel by using a dot reversible driving technique. The switching between two sets of input signals or two resolution modes is conducted by applying a DC voltage between the pixel electrode and the common electrode in each pixel before restart of the image display of a switched signal. The DC voltage has the same polarity among the pixels in the pixel array to thereby reduce the flicker after the restart of the image display.
