Abstract: An organic light-emitting display device having a signal line that is shared by a first column of pixels and a second column of pixels to transmit a data signal and a sensing signal. The organic light-emitting display device includes a plurality of columns of pixels, and a plurality of signal lines extending between the plurality of columns of pixels. Each of the plurality of signal lines is configured to transmit a data signal from a data driver to the first column of pixels at first times. The data signals control the operation of an organic light-emitting element in the first column of pixels. The same signal line transmits a sensing signal from the second column of pixels to the data driver at second times. The sensing signal represents a variable property of an electrical component in a pixel of the second column of pixels.
