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.
