Abstract

A liquid crystal display device that comprises a panel, a timing controller for providing control signals to the panel, a video chip for receiving video signals and providing decoded video signals to the panel, a phase lock loop for providing a reference clock frequency, and a source driver for receiving the control signals and video signals to drive the panel, wherein the timing controller, the video chip and the phase lock loop are incorporated into the source driver in an integrated circuit.

Claims (25)

1. A liquid crystal display device comprising:

a LCD panel;

a serial programmable interface for receiving operation frequency setting;

a synchronization separator coupled directly to said serial programmable interface and receiving said operating frequency setting from said serial programmable interface; and

an integrated circuit comprising;

a phase lock loop;

a video chip coupled directly to said LCD panel, directly to said serial programmable interface, directly to said synchronization separator, and directly to said phase lock loop, wherein said video chip receives video signals from a video source, decodes said video signals, and sends decoded video signals to said LCD panel;

a timing controller coupled directly to said serial programmable interface, said synchronization separator, and said LCD panel, wherein said timing controller receives operating frequency setting from said serial programmable interface, and generates timing control signal, provides said timing control signal to said LCD panel; and

a light emitting diode driver.

2. The device of claim 1 comprising a single voltage source for providing power to the liquid crystal display device.

3. The device of claim 1 comprising a power chip being incorporated into the integrated circuit.

4. The device of claim 1 comprising a common voltage circuit being incorporated into the integrated circuit.

5. The device of claim 1 , wherein said serial programmable interface is incorporated into the integrated circuit.

6. The device of claim 1 , wherein said synchronization separator is incorporated into the integrated circuit.

7. A liquid crystal display device comprising:

a LCD panel;

a timing controller, coupled directly to said LCD panel, for providing control signals to the LCD panel;

a phase lock loop of the drive system for providing a reference clock frequency;

a video chip, coupled directly to said LCD panel and directly to said phase lock loop, for receiving video signals from a video source, decoding said video signal, and providing decoded video signals to the LCD panel; and

a light emitting diode driver;

wherein the timing controller, the video chip, the light emitting diode driver, the timing controller, and the phase lock loop are incorporated into an integrated circuit.

8. The device of claim 7 comprising a power chip being incorporated into an integrated circuit.

9. The device of claim 7 comprising a common voltage circuit being incorporated into an integrated circuit.

10. The device of claim 7 comprising a serial programmable interface being incorporated into an integrated circuit.

11. The device of claim 7 comprising a synchronization separator being incorporated into an integrated circuit.
