A driving circuit and a gray insertion method of a liquid crystal display (LCD) are described. In the gray insertion method, whether a dynamic frame or a static frame display by the LCD is determined. When the LCD displays the dynamic frame, a gray insertion level of a frame of the display and a duty cycle of a pulse width module (PWM) signal are increased synchronously, wherein the PWM signal drives a back light module of the display. When the LCD displays the static frame, the gray insertion level of a frame of the display and the duty cycle of the PWM signal are decreased synchronously. As a result, a motion blur on LCD is reduced and luminance of a display frame is maintained.
