PANEL DEFECT DETECTION METHOD AND ORGANIC LIGHT-EMITTING DISPLAY DEVICE USING THE SAME

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.

1. An organic light-emitting display device comprising:
a display panel in which subpixels are disposed in a matrix, each subpixel including an organic light-emitting diode and a driving transistor; a sensing unit that senses a voltage on a sensing line and outputs a sensing value, the sensing line being electrically connected to a first node of a driving transistor in each subpixel on sensing subpixel lines corresponding to subpixel lines to be sensing-driven among a plurality of subpixel lines; and a detection unit that detects a panel defect based on sensing values according to the sensing subpixel lines in an amount equal to a predetermined number of sensing subpixel lines in at least one of predetermined regions in the display panel.
