Abstract: A compensation method of a display device includes: sensing a first luminance of the display device when a first pattern is displayed on the display device; calculating a luminance prediction value corresponding to a second pattern to be displayed on the display device based on the first luminance, where the second pattern is different from the first pattern; sensing a second luminance of the display device when the second pattern is displayed on the display device; adjusting a current flowing in a first power line of the display device until the second luminance reaches the luminance prediction value; and storing compensation data corresponding to an adjusted current in a lookup table when the second luminance reaches the luminance prediction value.

Abstract: A display device includes a display panel. The display panel includes a display panel including a data line, a sensing line, and pixels coupled to the data line and the sensing line. A timing controller generates clock embedded data including image data and a clock training signal. A data driver recovers a clock signal, based on the clock training signal of the clock embedded data, recovers the image data of the clock embedded data, based on the clock signal, supplies a data voltage corresponding to the image data to the data line in a first section, and receives a sensing signal from a pixel of the pixels through the sensing line in a second section different from the first section. In the second section, the data driver recovers the clock signal while the sensing signal is being received.

Abstract: A display device includes a display panel, a first memory, and a degradation compensator. The first memory device stores stress data including degradation values representing a degradation degree of each of the blocks in the display panel. The degradation compensator loads the stress data from the first memory device, updates the stress data based on current input data and a maximum degradation value, updates the maximum degradation value based on degradation values included in the updated stress data, and generate compensated data by compensating for the current input data based on the updated stress data. The degradation compensator determines whether a first degradation value included in the stress data is normal by comparing the first degradation value with the maximum degradation value, and updates the first degradation value based on at least one adjacent degradation value adjacent to the first degradation value, when the first degradation value is abnormal.
