Abstract
An organic light-emitting display panel includes a pixel unit including a plurality of pixels configured to display different colors, wherein the plurality of pixels is respectively disposed at intersections of a plurality of scan lines and a plurality of data lines; and a test unit configured to selectively apply, to a plurality of link lines connected to the data lines, a pixel test signal for detecting defects of the plurality of pixels and a link line test signal for detecting short and open states of the plurality of link lines.
Claims19
An organic light-emitting display panel, comprising:
- a pixel unit comprising a plurality of pixels configured to display different colors, wherein the plurality of pixels is respectively disposed at intersections of a plurality of scan lines and a plurality of data lines;
- and
- a test unit configured to selectively apply, to a plurality of link lines connected to the data lines, a pixel test signal for detecting defects of the plurality of pixels and a link line test signal for detecting short and open states of the plurality of link lines.
A method of testing an organic light-emitting display panel, comprising:
- applying a pixel test signal, for detecting a lighting defect of a plurality of pixels, to a plurality of link lines respectively connected to a plurality of data lines;
- and
- applying a link line test signal, for detecting short and open states of the plurality of link lines, to the plurality of link lines.
