摘要： A sealing layer covers more surely both of a display region and a peripheral region on a substrate. A dummy structure is formed in the peripheral region of the substrate. The dummy structure contains, for instance, at least one of the materials constituting an organic EL display structure. The dummy structure is located in the peripheral region so that the volume per unit area of the sealing layer in the peripheral region is substantially the same as that in the display region.

摘要： An organic light emitting display includes a data driver supplying a sensing data voltage in a sensing mode to prevent degradation of image quality occurring due to a kick-back phenomenon. Each pixel of a display panel of the organic light emitting display has its driving characteristic sensed in the sensing mode. The data driver is configured to supply a high driving voltage, which is higher than the supplied sensing data voltage, and both voltages are successively applied to a data line of the display panel in the sensing mode.

摘要： A panel defect detection method and an organic light emitting display device. A region having a high probability of a panel defect is intensively sensed through panel defect detection based on sensing results of characteristic values according to subpixels on sensing subpixel lines in an amount equal to the number of sensing subpixel lines preset in specific regions rather than all regions of a display panel. Rates and accuracy in detection of panel defects can be improved.
