Abstract
A pixel circuit includes a storage device directly connected to a control line so that a light-emitting device may emit light under a control of a control signal from the control line. The pixel circuit further includes: a first transistor; a second transistor; and a third transistor. A control terminal of the first transistor is connected to a first scan line, a second terminal of the first transistor is connected to an output node, and a first terminal of the storage device is connected to the output node. A control terminal of the second transistor is connected to the output node. A control terminal of the third transistor is connected to a second scan line, a second terminal of the third transistor is connected to an anode of the light-emitting device, and a cathode of the light-emitting device is grounded.
