Display device and drive method therefor

Abstract

The present application discloses a current-driven display device capable of providing satisfactory display without flickering even when pause drive is performed. In a pixel circuit, a first initialization transistor Tinitializes a gate voltage Vg, and thereafter a voltage on a data signal line Di is written to a holding capacitor Cst via a write control transistor Tand a drive transistor T. Thereafter, emission control transistors Tand Tare turned on, so that a drive current Ifrom the drive transistor Tcauses an organic EL element OL to emit light. During this emission period, even if the gate voltage Vg is decreased due to a leakage current through the first initialization transistor Tin an OFF state, the decrease is compensated for by increasing a threshold control voltage being provided to a threshold control terminal TG of the drive transistor T. Thus, even if the pause drive results in a long refresh cycle, it is possible to inhibit an increase in luminance due to the decrease in the gate voltage Vg and thereby prevent the occurrence of flickering.
