An organic light emitting display includes a display unit that includes scan lines and data lines. First sub-pixels, second sub-pixels, and third sub-pixels that emit light corresponding to different colors are repeatedly arranged in a uniform pattern. The organic light emitting display also includes a scan driver for supplying scan signals to the scan lines; a data driver coupled to one end of each of the data lines for supplying data signals to the data lines; a switch unit coupled between the one end of each of the data lines and the data driver to transmit the data signals supplied from output lines of the data driver to the data lines; and a test circuit unit including transistors coupled to other ends of the data lines. The first sub-pixels and the second sub-pixels are alternately arranged in same columns and the third sub-pixels are arranged in columns adjacent to the same columns.

Organic light emitting display and mother substrate thereof

An organic light emitting display is provided. In each circuit of pixels constituting a pixel unit, a transistor for providing an initialization voltage is arranged so that leakage current is reduced when the transistor is turned off. When the transistor is implemented as a dual gate transistor with a similar transistor from an adjacent pixel, layout space may be conserved.

Organic light emitting display

A pixel employable by a display device, including a plurality of transistors, including a first transistor having a gate electrode, and a capacitor including a first terminal connected to the gate electrode of the first transistor and a second terminal that is an intrinsic semiconductor.
