Abstract:
An electroluminescence display apparatus for performing display operations by causing the electroluminescence device, which comprises the anode and cathode, to emit light, comprising:a first thin-film transistor, having a source electrode connected to a holding capacitor, a drain electrode connected to a drain signal line, and a gate electrode connected to a gate signal line; a second thin-film transistor, having a drain electrode connected to the driving power supply of said electroluminescence device, and a gate electrode connected to the source electrode of said first thin-film transistor; a first diode and a second diode, which are connected in series in a forward direction toward the an-ode of said luminescence device from said second thin-film transistor, between the source electrode of said second thin-film transistor and said anode of said electroluminescence device; and a charging capacitor, which is connected between said first diode and said second diode; said driving power supply generating a periodically changing output voltage.
