IPC: G09G3/3258

Abstract: A power management device including a power management circuit is provided. The power management circuit is configured to output a first power signal and a second power signal to a pixel circuit of a display panel. The pixel circuit includes an organic light-emitting diode. The organic light-emitting diode includes an anode terminal and a cathode terminal. The anode terminal is coupled to the first power signal. The cathode terminal is coupled to the second power signal. The second power signal is an alternating-current voltage. In addition, a pixel circuit of a display panel, and a power management method for the pixel circuit of the display panel are also provided.
