Patent ID: 8860637

Claim:
An electro luminescence display panel comprising: a plurality of pixel circuits, at least one of the plurality of pixel circuits including a driving transistor for drawing a driving current from a fixed-voltage power-supply line and supplying said driving current to an organic electro luminescence device, a signal holding capacitor connected between a gate electrode and a source electrode of said driving transistor, and a sampling transistor for controlling an operation to store a signal electric potential into said signal holding capacitor; a capacitor control line connected to the plurality of pixel circuits; a coupling capacitor connected between an anode electrode of said organic electro luminescence device and said capacitor control line; and a pulse voltage source for raising an electric potential appearing on said capacitor control line from a low level to a high level at a start of a horizontal scan period and lowering said electric potential from said high level back to said low level at least one time during the horizontal scan period before said signal electric potential is supplied to a signal line.
