Abstract
A driving circuit for driving an LCD includes a common electrode, a number of pixel electrodes, a peripheral circuit, and a processing unit including a first input/output (I/O) port, a second I/O port; and a number of third I/O ports. The first I/O port and the second I/O ports are connected to the common electrode via the peripheral circuit, and each third I/O port is connected to a different pixel electrode. The processing unit controls the first I/O port, the second I/O port, and the third I/O ports to output a first or second voltage according to a display signal, thus the pixel electrodes are at the first or the second voltage accordingly, the common electrode is at a voltage in a range between the second voltage and the first voltage in receiving the voltage output by the peripheral circuit, thus driving the LCD to display an image.
