Abstract: A drive apparatus of a display panel is provided with an anode driver that drives m anode lines CL, a cathode driver that scans n cathode lines RL, and control means. In a process of pre-charging a parasitic capacity Cp of display elements connected to any of the scan lines RL whichever selected by the cathode driver, the control means switches a connection of L of the n scan lines RL and the m anode lines CL to a ground terminal, and applies voltage control with (L/n)×Vccr for application of an initial output voltage of the anode driver at about an EL element drive voltage Vf. In this manner, the parasitic capacity Cp of the EL elements connected to L scan lines RL is pre-charged. With such a drive apparatus of the display panel, without causing to be complicated in configuration, and without increasing the size of the circuit, it becomes possible to set and control a voltage for pre-charging a parasitic capacity of organic EL elements to be any needed voltage or current.
