ABSTRACT:
The output current from respective output terminals of a drive circuit (driver IC) of an organic EL display panel to respective column pins or data lines is sequentially selected by sequentially scanning a plurality of switch circuits by a switch scan circuit. The resultant output currents are converted into voltage values by resistors selected by a selector. Further, the converted voltage values sequentially generated according to the scanning of the switch scan circuit are outputted externally of the IC.
