Abstract: The present application relates to a driving circuit for display panel, which drives a plurality of pixel structures of a display panel. Each of pixel structures comprises a light emitting element, which is coupled between a first voltage and a second voltage. The driving circuit comprises a power supply circuit, which is coupled to the pixel structures, provides the first voltage and the second voltage, and adjusts the first voltage or/and the second voltage for adjusting a voltage difference between the first voltage and the second voltage. That is, a current flowing through the light emitting elements of the pixel structures may be adjusted for reducing the flicker in the display panel.
