1. A display device, comprising:
a display panel including a plurality of pixels, the display panel being configured to be driven in a first driving period, a blank period after the first driving period, and a second driving period after the blank period;
a data driver configured to:
provide a data voltage to at least one of the pixels to display an image based on a compensated image data; and
detect a sensing voltage from a reference voltage line connected to the at least one of the pixels to convert the sensing voltage into a sensing data during the first driving period and the second driving period; and
a timing controller configured to:
determine a first compensation data based on a difference between the sensing data detected during the first driving period and the sensing data detected during the second driving period; and
determine the compensated image data based on an input image data and the first compensation data.
