Abstract
The present invention relates to a driving circuit for a display panel, and comprises a switching module, a buffer circuit, and a plurality of resistive devices. The switching module is coupled to a first power supply and a second power supply. The voltage of the first power supply is smaller than that of the second power supply. The buffer circuit is coupled to the switching module, and is used for buffering a data signal and producing a buffer signal. The plurality of resistive devices is connected in series and coupled to the buffer circuit, and produces a plurality of driving signals between the plurality of resistive devices according to the buffer signal. The driving circuit switches between the first power supply and second power supply sequentially to supply power to the buffer circuit. Thereby, one of the plurality of driving signals charges a capacitor of the display panel for saving power of the driving circuit. Accordingly, the power of the display can be saved.
