Abstract
The present invention provides a driving circuit for panel, which comprises a gamma voltage generating circuit, a plurality of selecting units, and at least a source driving circuit. The gamma voltage generating circuit generates a plurality of gamma voltages for the plurality of selecting units. The plurality of selecting units outputs the plurality of gamma voltages generated by the gamma voltage generating circuit using the time-division method according to selection data to the source driving circuit. According to display data, the source driving circuit selects to receive the gamma voltage of an output of the plurality of selecting units as a target voltage. In addition, the source driving circuit produces a driving signal according to the target voltage for driving a panel.
