Abstract: The present invention provides a circuit for driving a display panel using a driving capacitor, comprising an analog-to-digital converter receiving an analog input signal to generate a digital signal, a driving capacitor receiving the digital signal to generate a driving signal for the display panel, and a switching circuit in response to a switching signal, selectively coupling the analog-to-digital converter to the driving capacitor for transmission of the digital signal and coupling the driving capacitor to the display panel for transmission of the driving signal. Thus, the circuit area needed for a source driver processing images of large bit number is reduced, which decreases the cost. Further, the power system of the display having a large dynamic range of voltage can be also simplified.
