DISPLAY DEVICE AND METHOD FOR CONTROLLING THE SAME

摘要

A display device includes: an organic EL element (110); a capacitance element (150); a drive transistor (120) which applies current based on a voltage held in the capacitance element (150) connected to an anode of the organic EL element (110), to the organic EL element (110) so as to emit light; a data line (31) which supplies a signal voltage to the capacitance element (150); a switching transistor (130) which connects a data line (31) to the capacitance element (150); a voltage detection circuit (50) which is connected to the data line (31) and detects an anode voltage; an inspection transistor (140) which connects the anode to the data line (31); and a control unit which turns ON the switching transistor (130), causes the capacitance element (150) to hold a voltage corresponding to the signal voltage so that the organic EL element (110) emits light, and turns OFF the switching transistor (130) and turns ON the inspection transistor (140) while the organic EL element (110) is emitting light, and causes the voltage detection circuit (50) to detect an anode voltage.
