Abstract
During a vertical scanning period, the potential of one of the two electrodes which LC capacitors connected to each scanning line have is changed, and meanwhile the potential of the other has a coupled voltage caused from the change. The pixel electrode connected to the other one electrode of the LC capacitor also has a potential change caused from the coupled voltage so that the coupled voltage is written into the LC capacitor to turn the pixel black. That is, during one vertical scanning period, each pixel turns true black or near black from a predetermined gradation. Therefore, the LCD panel can have a sharp image, and is suitable for displaying a fast continuous movement.
