Abstract
The present invention relates to an area-saving driving circuit for a display panel, which includes a plurality of digital-to-analog converting circuits convert input data, respectively, and produce a pixel signal. A plurality of driving units are coupled to the plurality of digital-to-analog converting circuits, respectively. They produce a driving signal according to the pixel signal and transmit the driving signal to the display panel for displaying. A plurality of voltage booster units are coupled to the plurality of driving units, respectively, and produce a supply voltage according to a control signal. Then the supply voltage is provided to the plurality of driving units. Thereby, by providing the supply voltage to the plurality of driving units of the display panel through the use of the plurality of voltage booster units, the area of the external storage capacitor is reduced or eliminated.
