Abstract
A light emitting display which includes pixel circuits, each of the pixel circuits being operated by at least two different scan signals and being capable of performing a bi-directional scanning operation. The light emitting display includes a bi-directional signal transmission shift register, the pixel circuits, and a signal applier. Each of the pixel circuits is provided with two or more scan lines. The scan lines include first and second scan lines. The shift register outputs first signals in a first direction in response to a first control signal, and outputs second signals in a second direction opposite to the first direction in response to a second control signal. The signal applier sequentially applies, to the scan lines of the pixel circuits, first scan signals corresponding to respective ones of the first signals or second scan signals corresponding to respective ones of the second signals.
