An EL display panel, an electronic apparatus and a driving method of EL display panel are provided to coupling-drive the anode voltage of the organic electroluminescent display and the gate voltage of the driving transistor. An EL display panel comprises a driving transistor(T2), a pixel circuit(71), a capacity control line(CNTL), a coupling capacitance and a pulsed voltage source(45). The driving transistor receives the driving current from the fixed voltage power line and supplies to the organic light emitting diode. The pixel circuit has the signal maintenance capacity(Cs) and a sampling transistor. The signal storage capacitance is arranged between the gate electrode and the source electrode of the driving transistor. The sampling transistor(T3) controls the operation of storing the signal electric potential(Vsig) of the organic light emitting diode and the signal storage capacitance. The capacity control line is connected to the pixel circuit through the common line. |
