Patent ID: 6963172

Claim:
An organic EL element drive circuit for current-driving organic EL elements in a manner that a display period corresponding to a horizontal scan period and a reset period corresponding to a retrace period of a horizontal scan line are provided and said organic EL elements are current-driven through terminal pins in the display period and terminal voltages of said organic EL elements are reset in the reset period, said organic EL element drive circuit comprising: switch circuits for resetting said organic EL elements by setting anode sides of said organic EL elements to a predetermined potential through said terminal pins in the reset period; peak current generator circuits for generating peak currents superposed on the drive currents of said organic EL elements; a reset inhibit circuit for inhibiting a resetting by said switch circuits and stopping generation of the peak currents by said peak current generator circuits; and determination means for determining whether the drive current for the current display period is substantially the same as that in the display period of a next horizontal scan line, said reset inhibit circuit being actuated to inhibit the resetting and stopping the generation of the peak current when said determination means determines that the drive current for the display period of a current display period is substantially the same as that of a next horizontal scan line.
