Abstract
Supplying first and second measuring voltages to a source terminal of a drive transistor to obtain first and second voltage variations at the source terminal of the drive transistor when a parasitic capacitance of a light emitting element is charged by currents flowed through the drive transistor by the supply of the voltages, obtaining first and second current values of the drive current of the drive transistor based on the first and second voltage variations, obtaining characteristic values of the drive transistor based on the first and second measuring voltages and the first and second current values, and outputting a data signal based on the obtained characteristic values and a drive voltage of the drive transistor corresponding to the amount of emission of the light emitting element to the source terminal of the drive transistor.
