Claim Text:
1. An organic light-emitting display device, comprising: a data driver configured to generate data signals; a plurality of signal lines connected to the data driver to transmit at least the data signals; and a plurality of pixels comprising a first column of pixels and a second column of pixels, each pixel in the first column of pixels comprising: a first transistor between the first signal line of the plurality of signal lines and a first node, the first transistor configured to selectively connect the first node to the first signal line to receive a data signal for the pixel during first times; a second transistor connected to a second node and configured to control a supply of a reference voltage during the first times; an organic light emission element connected to the second node and a low supply voltage line; a driving transistor between a high supply voltage line and the second node, the driving transistor configured to generate driving currents through the organic light emission element during the first times, wherein the driving transistor is configured to operate according to a voltage at the first node; a storage capacitor connected between the first and second nodes to maintain the data voltage; and a third transistor between the second node and a second signal line of the plurality of signal lines, the third transistor configured to selectively connect the second signal line to transmit sensing signals representing a threshold voltage of the driving transistor from the second node during second times, the second signal line transmitting data signals for pixels in the second column of pixels during the first times, wherein the second times comprise vertical blank periods.
