Title:
DISPLAY DEVICE AND METHOD OF CONTROLLING SAME
Document Type and Number:
WIPO Patent Application WO/2015/162650
Kind Code:
A1
Abstract:
A display device (1) is provided with: an organic electroluminescent (EL) element (110); a capacitance element (160); a drive transistor (120); a data line (31); an inspection transistor (150) for switching electrical continuity between the data line (31) and the anode electrode of the organic EL element (110) on and off; a voltage generation unit (30) for supplying, to the data line (31), an examination voltage for measuring the anode voltage; a current detection unit (40) for detecting a current flowing in the inspection transistor (150) when the inspection transistor (150) is placed in an electrical continuity state while the examination voltage is applied from the voltage generation unit (30) to the data line (31); and a control unit (50) for updating the voltage value of the examination voltage on the basis of the direction in which the current detected by the current detection unit (40) flows and having the voltage generation unit (30) output the updated examination voltage.
