<P>PROBLEM TO BE SOLVED: To improve flexibility in the operation design by conducting Vth compensation and reverse bias application in a single operating process. <P>SOLUTION: By connecting the gate of a driving transistor T3 and one of its own terminals and applying a non-forward bias to the driving transistor T3, the voltage of a node N1 connected to the gate of the driving transistor T3 is set to an offset level corresponding to the Vth of the driving transistor. Then, by applying a data voltage Vdata to a data line X which is coupled in capacitance to the node N1, data writing is conducted to capacitors C1 and C2 connected to the node N1 using the offset level as a reference. Then, by applying a forward bias to the driving transistor T3, a driving current Ioled is generated, and luminance of an organic EL element OLED is set by the driving current. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
