Abstract: Disclosed is a pixel circuit. The pixel circuit includes: a capacitor coupled between a first node and a second node; a driving element connected to a first constant voltage node, the second node, and a third node; a light emitting element connected to a fourth node and a second constant voltage node; a first switch element; a second switch element; a third switch element connected between the fourth node and the second constant voltage node or between the fourth node and a fourth constant voltage node; a fourth switch element connected between the first node and a third constant voltage node; a fifth switch element connected between the second node and the third constant voltage node or between the first node and the second node; and a sixth switch element connected between the third node and the fourth node.

Abstract: Disclosed herein are a gate driving circuit and a flexible display using the same. In gate driving circuit, a control block including an nth controller configured to generate one among a gate-off voltage, an EM start signal, and a carry signal from a (n-1)th EM signal transfer part as an nth EM output control signal to apply the nth EM output control signal to a start terminal of an nth EM signal transfer part on the basis of an nth scan signal (n is a natural number) from the first shift register, a first control signal designating an off-driving signal transfer parts and an on-driving signal transfer parts among the EM signal transfer parts, a second control signal designating a first on-driving signal transfer part, and a third control signal designating second to last on-driving signal transfer parts.
