    Abstract: A display device includes an afterimage compensator generating output grayscales by applying at least one of first and second weights to input grayscales when the input grayscales correspond to a still image, and pixels displaying an image based on the output grayscales. The afterimage compensator applies the first weight having an initial value greater than 1 to the input grayscales of a first group, and converges the first weight to 1, and applies the second weight having initial values less than 1 to the input grayscales of a second group, and converges the second weights to 1.

    Abstract: A display device includes a display part, a degradation compensator that generates a first compensated grayscale value by compensating for a first grayscale value corresponding to a first pixel, and generates a second compensated grayscale value by compensating for a second grayscale value corresponding to a second pixel, and a data driver that generates a first data signal based on the first compensated grayscale value to supply the first data signal to the first pixel, and generates a second data signal based on the second compensated grayscale value to supply the second data signal to the second pixel. A second degradation curve is defined by a first degradation coefficient corresponding to a first degradation curve, and a second degradation coefficient corresponding to a first estimated degradation curve for the light conversion particles of a second color calculated by applying the first degradation curve.

    Abstract: A data driver includes a multi-channel sample/hold circuit electrically connected between a digital-to-analog converter and a data buffer. The multi-channel sample/hold circuit includes a first sample/hold circuit connected to a first channel and a second sample/hold circuit connected to a second channel. The first sample/hold circuit performs a first drive operation and a second drive operation. The first drive operation includes sampling a data voltage as a buffer input voltage and maintaining the buffer input voltage during an nth horizontal time. The second drive operation includes outputting the buffer input voltage to an output terminal of the buffer during an (n+1)th horizontal time. The second sample/hold circuit performs the second drive operation during the nth horizontal time and performs the first drive operation during the (n+1)th horizontal time.
