Abstract
Disclosed are a display device and a driving method thereof. A reference compensation voltage for compensating for a node voltage of each pixel for an image holding period after a refresh period for which image data is input in a low-speed driving mode is set. Then, the node voltage of each sub-pixel is compensated for using a corresponding reference compensation voltage on at least one frame basis at each start time and each end time of the image holding period, thereby preventing low image quality and reducing power consumption.
