Patent number: 8937584Abstract: 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.Type: GrantFiled: June 1, 2010Date of Patent: January 20, 2015Assignee: Samsung Display Co., Ltd.Inventors: Won-Kyu Kwak, Dong-Wook Park, Hae-Jin Chun

Patent number: 8174183Abstract: 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.Type: GrantFiled: May 19, 2008Date of Patent: May 8, 2012Assignee: Samsung Mobile Display Co., Ltd.Inventors: Won-kyu Kwak, Hae-jin Chun
