Abstract
The present invention provides an integrated LCD panel power supply formed on a single printed circuit board. The integrated power supply includes at least one DC/AC control unit, at least one DC/DC buck converter unit and at least one DC/DC boost control unit. Each unit supplies power to an associated function of said LCD. The integrated power supply may also include an oscillator circuit generating a clock signal, and the clock signal is supplied to each unit thereby synchronizing the operation of each unit. The single PCB approach of the present invention eliminates the need for additional wiring between printed circuit boards and thereby eliminates or substantially reduces noise issues associated with such wiring.
