  • Patent number: 8937584
    Abstract: 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.

  • Patent number: 8907869
    Abstract: 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.

  • Patent number: 8174183
    Abstract: A mother substrate is provided including organic light emitting displays. The organic light emitting displays have a pad unit formed at one side. First and second wiring line groups extend in first and second directions, respectively, on the organic light emitting displays. The first and second wiring line groups are coupled to each pad unit. Intersection parts between the first and second wiring line groups are within scribing lines of each of the organic light emitting displays in which the first and second wiring line groups intersect. Partial regions of the second wiring line group excluding the intersection parts are within scribing lines of an adjacent one of each of the organic light emitting displays. Via holes are located through a protecting layer to expose the first and second wiring line groups where the first and second wiring line groups couple to the pad unit.

  • Patent number: 7944140
    Abstract: An organic light emitting display and a method of manufacturing the same. The light emitting display includes a substrate having a pixel region and a non-pixel region; an organic light emitting diode (OLED) in the pixel region and including a first electrode, an organic thin layer, and a second electrode; a driving circuit unit in the non-pixel region and for driving the OLED; a shielding layer in the non-pixel region and on the driving circuit unit, the shielding layer being electrically coupled to a ground power source; and an insulating layer interposed between the driving circuit unit and the shielding layer. The shielding layer effectively protects the driving circuit unit in the non-pixel region form electrostatic discharge (ESD). Also, the light emitting display may include a guard ring at an edge portion of the non-pixel region and electrically coupled to the shielding layer to further protect the driving circuit from ESD.
