Patent ID: 7907108

Claim:
A source driving circuit for driving a data line of a display, comprising: a source driver circuit that receives display data and generates a source driving voltage corresponding to the received display data, and applies the source driving voltage to a data line of a display; a voltage generator circuit that generates an intermediate source driving voltage, wherein the intermediate source driving voltage is a first intermediate voltage in a first mode of operation and the intermediate source driving voltage is a second intermediate voltage lower than the first intermediate voltage in a second mode of operation; and a control circuit that applies the intermediate source driving voltage to the data line to drive the data line when the received display data is different from previously received display data before the source driving voltage is applied to the data line by the source driver circuit to drive the data line, wherein the intermediate source driving voltage is in a range of ½ to ⅓ of a full-swing voltage of the source driving voltage, wherein in the first mode of operation the source driving voltage is either a power supply voltage or a ground voltage and in the second mode of operation the source driving voltage is a grayscale voltage.
