Abstract
A light display includes scan lines arranged in a row direction to transmit scan signals, a data line arranged in a column direction to transmit a data signal, an image display unit including emission control lines arranged in the row direction to transmit emission control signals, and a pixel in a region defined by the scan lines and the data line. The pixel has a driving circuit for receiving the signals, the data signal, the emission control signals, and a power to drive a current, a switching circuit connected with the driving circuit to receive the current, the switching circuit for selectively applying the current in accordance with the emission control signals, and organic light emitting diodes (OLEDs) positioned on different rows of the image display unit and connected with the switching circuit to receive the current in accordance with an operation of the switching circuit and to emit light.
