ORGANIC EL PANEL DRIVE CIRCUIT AND PROPRIETY TEST METHOD FOR DRIVE CURRENT OF THE SAME ORGANIC EL ELEMENT DRIVE CIRCUIT

摘要

First analog current through the plurality of switch circuits provided corresponding to the output pin of the organic EL driving circuit or obtained as the drive current is obtained through the output stage current source. The first analog current or the driving current is compared with the obtained current by sending a second analog current (reference current) or the second analog current through the current source corresponding to the output current source by a comparison circuit provided in the organic EL device driving circuit . Driving current, the organic EL device so as to obtain a comparison result to the driving current from the driving circuit sequentially, successively obtained in the output pin by turning a switch circuit sequentially one by one by the control circuit.
