The present disclosure relates to a display device and a driving method thereof, wherein a refresh rate of pixels is controlled at a reference frame frequency in a normal driving mode, and the refresh rate of the pixels is controlled at a frequency lower than the reference frame frequency in a low speed driving mode. In the low speed driving mode, park data is transmitted to a data driving circuit during at least one vertical blank period.

Display device and driving method thereof

The present disclosure relates to a display device and an image processing method thereof, and includes a pixel shift processing unit configured to shift an image displayed in an active pixel region within the size of a dummy pixel region. The pixel shift processing unit gradually changes a gray level of at least one dummy pixel in the dummy pixel region adjacent to the active pixel region up to a target gray level of pixel data, and gradually changes a gray level of at least one active pixel of an active pixel adjacent to the dummy pixel region up to a black gray level when the active pixel region is shifted.
