    Abstract: An organic light emitting display device having a data line that is used for sending data voltage signals to pixels from a data driver as well as send sensor signals for detecting threshold voltage levels of driving transistors in the pixels at different times. By using the same data line to transmit the data voltage signals and the sensor signals, the number of signal lines in the organic light emitting display can be reduced. The data driver also includes switches for selectively coupling the data line to a driver unit or an analog to digital converter (ADC) unit.

    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.
