Abstract: A pixel compensation module according to one embodiment of the present disclosure detects a degraded region with reference to degradation data corresponding to each of pixels included in a display panel, determines a first compensation gain so as to decrease final compensation data of pixels included in the degraded region, and determines a second compensation gain so as to increase final compensation data of pixels included in an adjacent degraded region to correct compensation data of the pixels.

Abstract: Embodiments of the present disclosure relate to a data driving circuit, a controller and a display device. A display driving is performed by outputting the number of internal data enable signals that is smaller than the number of external data enable signals in the display device performing high-speed driving. As a result, it is possible to prevent an increase in the load of the data driving circuit according to the high-speed driving. In addition, a part of the internal data enable signals is output during a blank period to prevent a decrease in the interval between the internal data enable signals and to increase the number of internal data enable signals. This can improve the image quality displayed on the display panel while preventing an increase in the load on the data driving circuit.
