Abstract: A display driving circuit including: a data driver configured to supply driving signals to a plurality of pixels of a display panel and sense electrical characteristics of each of the plurality of pixels; and a degradation compensation circuit configured to generate and store an accumulated degradation value by, accumulating degradation values for each of a plurality of pixel blocks for a unit time, based on driving data corresponding to the driving signals, correct the accumulated degradation value of a first pixel block, based on sensing data received from the data driver, and perform data compensation to compensate for pixel degradation, based on the accumulated degradation values and a degradation model, wherein each pixel block includes at least one pixel.
