Abstract: The present invention relates to a power circuit of displaying device, which comprises a timing controller, a control circuit, and a charge pump (single or multiple stages). The timing controller outputs a timing control signal to the control circuit. The control circuit outputs a clock signal or a capacitance adjusting signal according to the timing control signal. The charge pump receives the input voltage and outputs an output voltage according to the clock signal or the capacitance adjusting signal. The output voltage is provided to the scan driver for generating a plurality of scan driving signals. Accordingly, by increasing the rise rate of the output voltage of the charge pump in the voltage conversion time and reducing the rise rate of the output voltage close to the voltage holding time, the present invention can achieve the effect of reducing the power consumption.

Abstract: The present invention relates to a driving method for flicker suppression of a display panel and a driving circuit thereof. The driving circuit includes a source driving circuit and a common voltage generating circuit. The driving method includes driving the source driving circuit to generate at least one first source signal and at least one second source signal, the first source signal corresponds to at least one first pixel on a first scanning line; the second source signal corresponds to at least one second pixel on a second scanning line. The common voltage generating circuit generates at least one common voltage. While driving the first pixel and the second pixel to display the same gray scale image, the first source signal is not equal to the second source signal, or a first common voltage and a second common voltage generated by the common voltage generating circuit are different.
