A time point at which each of transistors is turned on is controlled without using an additional transistor so that a node connected to a source electrode of a driver transistor can be floated, and a node connected to a gate electrode of the driver transistor can be initialized to an initialization voltage level. Thus, initialization characteristics can be improved to enhance degradation of response characteristics and luminance, and a threshold voltage of the driver transistor and occurrence of a ripple at a high-potential voltage terminal can be compensated.

Abstract: Provided is an OLED display device that is in a black mode in which a threshold voltage of a driving TFT need not accurately be sensed. Further, a low voltage value of zero or less is constantly and continuously supplied to a data line during an initialization period, a sampling period, and a programming period in a pixel. As a result, when the pixel is driven in the black mode, a reference voltage and a data voltage having different values are not alternately supplied to the data line to minimize power consumption.
