Patent ID: 7180438

Claim:
A source driver for a display panel, at least comprising: a data-receiving device used for receiving, registering a data signal and outputting the data signal; a data switch set connected to the data-receiving device, for selectively conducting the data signal from the data-receiving device in response to a first timing signal; a voltage generator, having multiple voltage generating circuits, used for generating a plurality of voltages according to a plurality of reference voltages; a voltage switch set connected to the voltage generator, for selectively conducting the voltages from the voltage generating circuits in response to a second timing signal; a digital to analog (DAC) set connected to the data switch set and the voltage switch set, for receiving and outputting the selectively conducted voltages according to the selectively conducted data signal; an output unit set connected to the DAC set, for receiving the selectively conducted voltages from the DAC and providing an output voltage in response to a third timing signal; and a timing control device used for providing the first, the second, and the third timing signals.
