    Abstract: A display device may include a pixel unit which includes pixels, a driver which drives the pixel unit based on image data, a voltage generator which provides a driving voltage to the pixel unit, and a global current manager including a compensation voltage generator which receives a comparison result between a sensing current of the pixel unit and a reference current range generated based on the image data from a comparator and generates a compensation voltage for controlling the driving voltage, and a compensation data generator which generates compensation data for controlling grayscale values of the image data in a dithering method based on the comparison result.

    Abstract: A display apparatus includes a display panel, a gate driver and a data driver. The display panel is configured to display an image. The gate driver is configured to output a gate signal to the display panel. The data driver is configured to output a data voltage to the display panel. The display panel includes a first subpixel row including first subpixels having a first color and a second subpixel row including second subpixels having a second color. A first gate off voltage of a first gate signal applied to the first subpixel row to turn off switching elements of the first subpixel row is different from a second gate off voltage of a second gate signal applied to the second subpixel row to turn off switching elements of the second subpixel row.

    Abstract: A driving controller of a display device includes a timer which counts an operation time and outputs a count signal, a memory which stores compensation data, a control signal generation part which receives the compensation data from the memory in response to the count signal and outputs a compensation data signal corresponding to the compensation data, and an image processor which converts an image signal into a data signal and outputs the data signal, where the data signal is obtained by combining the image signal and the compensation data signal. The compensation data includes first compensation data corresponding to a first operation time and second compensation data corresponding to a second operation time which is different from the first operation time.
