Abstract
A liquid crystal display replaces the common electrodes of a conventional LCD with a plurality of switch electrodes. The plurality of switch electrodes is grouped into several switch electrode sets. Each of the switch electrode sets' potential is modulated by a different driving circuit. The driving circuits can also separately modulate the potentials of the switch electrode sets according to the scanning sequence of the LCD.
