Abstract:
The present application discloses a current-driven display device which employs internal compensation, by which a non-emission period can be shortened without causing the luminance of display elements to be unstable. During a period in which a voltage on a data signal line Dj is written to a pixel circuit, transistors M4 and M6 are controlled to be in an OFF state, and transistors M2, M3, and M5 are controlled to be in an ON state. As a result, a drive transistor M1 is diode-connected, a source terminal thereof is disconnected from a high-level power line ELVDD, and a gate terminal thereof and an anode of an organic EL element OLED are connected to an initialization voltage supply line Vini. Consequently, a gate voltage Vg of the drive transistor M1 and an anode voltage Va of the organic EL element OLED are initialized, and first and second capacitors C1 and C2 respectively hold a voltage corresponding to the voltage on the data signal line Dj and a threshold voltage of the drive transistor M1.
