Display device with threshold voltage compensation and driving method thereof

摘要

A display device is provided that can provide sufficient time for threshold voltage compensation of a driving transistor of each pixel during high-speed driving of the display device, and a method for driving the same. A data writing and threshold voltage compensation step of pixels at odd and even-numbered lines are concurrently performed during an extended time period so that the time available for threshold voltage compensation of the driving transistors can be increased.

1. A display device comprising:
a scan driver configured to apply scan signals of a (k−1)-th odd-numbered line and a k-th odd-numbered line to a pixel of the k-th odd-numbered line, and apply the scan signal of the (k−1)-th odd-numbered line, the scan signal of the k-th odd-numbered line, and a scan signal of a k-th even-numbered line to a pixel of the k-th even-numbered line (here, k is an integer and greater than 2); and a data driver configured to apply a first data signal of the k-th odd-numbered line to data lines respectively connected to a pixel of the k-th odd-numbered line and a pixel of the k-th even-numbered line corresponding to the scan signal of the k-th odd-numbered line, and apply a second data signal of the k-th even-numbered line to the data line corresponding to the scan signal of the k-th even-numbered line, wherein a threshold voltage of a driving transistor of the pixel of the k-th odd-numbered line and a threshold voltage of a driving transistor of the pixel of the k-th even-numbered line are compensated for according to the scan signal of the k-th odd-numbered line, and wherein the scan signal applied to the k-th odd-numbered line is different from that applied to the k-th even-numbered line.
