摘要： Disclosed are a device and method for sensing the threshold voltage of a driving TFT included in an organic light emitting display so that a change in the threshold voltage of the driving TFT is sensed during real-time operation by reducing sensing time. First and second sensing voltages are obtained by fast sensing in the TFT linear region, and a change in the threshold voltage of the driving TFT is obtained based on the sensing ratio between the sensing voltages. Thus, a number of processes for deducing a change in threshold voltage, i.e., programming, source node resetting, sensing, and sampling, may be performed during the vertical blanking interval. That is, it is possible to sense a change in the threshold voltage of the driving TFT DT during real-time operation, without the need of arranging a time during power-on or power-off in order to sense a threshold voltage change, thereby improving compensation performance.
