The present invention provides a clock driver of a liquid crystal display, including a primary timing control chip, a secondary timing control chip, display driving ports, a backlight driving port, a first storage device, a second storage device, and a data input port. The display driving ports are electrically connected to a liquid crystal panel. The backlight driving port is electrically connected to the backlight driving circuit. The primary and secondary timing control chips receive a control signal from the data input port and supply a display timing control signal and a display data signal via the display driving port to the liquid crystal panel according to the control signal. Further, the secondary timing control chip outputs, via the backlight driving port, a pulse width modulation signal to the backlight driving circuit. The clock driver uses two timing control chips to drive the liquid crystal panel and the backlight source. |
