Abstract

A display device including a display panel and a driving circuit is provided, wherein the driving circuit includes a synchronizer and a driver. The synchronizer synchronizes a plurality of external control signals according to an internal clock and accordingly generates a plurality of internal control signals. The driver reads the internal control signals according to the internal clock and accordingly generates a plurality of driving signals to drive the display panel.

Claims

1. A driving circuit, for driving a display panel, the driving circuit comprising:

a synchronizer, for synchronizing a plurality of external control signals according to an internal clock and accordingly generating a plurality of internal control signals; and

a driver, for reading the internal control signals according to the internal clock and accordingly generating a plurality of driving signals to drive the display panel.

2. The driving circuit according to claim 1 further comprising a clock generator for generating the internal clock.

3. The driving circuit according to claim 2, wherein the clock generator is a RC oscillator.

4. A display device, comprising:

a display panel; and

a driving circuit, comprising;

a synchronizer, for synchronizing a plurality of external control signals according to an internal clock and accordingly generating a plurality of internal control signals; and

a driver, for reading the internal control signals according to the internal clock and accordingly generating a plurality of driving signals to drive the display panel.

5. The display device according to claim 4, wherein the driving circuit further comprises a clock generator for generating the internal clock.

6. The display device according to claim 5, wherein the clock generator is a RC oscillator.
