摘要： Provided are a display driving device capable of accurately detecting characteristics of pixels of a display panel regardless of an offset of an amplifier, and a display device including the same. The display device includes a display panel including pixels and a display driving device including a sense circuit configured to detect pixel signals from the pixels. The sense circuit includes sense amplifiers configured to provide the first reference voltage to the pixels so that the pixels are programmed using a first reference voltage in a programming mode.

摘要： Disclosed are a source driver for sensing the degree of deterioration in pixels in some regions of a display panel and compensating for the deterioration in the display panel based on the sensed degree, by considering a characteristic in which pixels included in each display panel similarly deteriorate, and a display device including the same. The display device may include a display panel including pixels, a sensing circuit configured to provide sensing data by sensing the degree of deterioration in pixels in at least one first region of the display panel, and a compensation circuit configured to calculate an amount of compensation of each of the pixels in the first region using the sensing data and compensate for the deterioration in the pixels in the first region and pixels in a second region whose degree of deterioration is not sensed, based on the amount of compensation.
