ABSTRACT:
The invention provides an organic LED display device of the digital drive type which has a display panel comprising a plurality of pixels51. Each of the pixels51comprises an organic EL element50, a drive transistor TR2for effecting or interrupting the passage of current through the EL element50in response to the input of an on/off control signal, a write transistor TR1to be brought into conduction upon receiving scanning voltage applied thereto from a scanning driver, a capacitance element C to be supplied with data voltage from a data driver by the write transistor TR1conducting, and a comparator9for comparing a predetermined ramp voltage with the output voltage of the capacitance element C and supplying the result of comparison to the drive transistor TR2as the on/off control signal.
