Abstract: A display device includes a memory, a signal controller, and a voltage generator. A plurality of data is stored in the memory. The signal controller detects a frame rate of an externally applied image data signal, selects data corresponding to the detected frame rate among the plurality of data, and outputs a control signal corresponding to the selected data. The voltage generator includes a DC-DC converter for determining an output voltage in correspondence to the control signal and a feedback circuit for determining a current flowing inside and a frequency of an outputted signal in correspondence to the control signal.

Abstract: A display system includes a measurer, a measured data filter and a compensation data generator. The measurer measures an image at a measuring point of a display panel to generate measured data. The measured data filter removes a false measured data outside an allowable range among the measured data. The compensation data generator generates representative compensation data compensating the image based on the measured data in which the false measured data is removed.

Abstract: In a method of operating a display apparatus, during a first period in which image data is provided to a data driver, a clock embedded data signal having an output differential voltage (“VOD”) set to a first voltage value is applied to the data driver. The VOD of the clock embedded data signal relates to a voltage difference between a high level and a low level of the clock embedded data signal. During a second period in which the image data is not provided to the data driver, the VOD of the clock embedded data signal applied to the data driver is changed to a second voltage value smaller than the first voltage value.

Abstract: A display device includes a display panel which includes a pixel including a driving transistor and a light-emitting element, and a sensing line connected to the pixel. A sensing driver senses a first sensing signal corresponding to mobility of the driving transistor through the sensing line, and processes the first sensing signal to output first sensing data. A driving controller receives the first sensing data from the sensing driver, generates mobility compensation data and kickback compensation data based on the first sensing data, and converts image data into compensation image data by the mobility compensation data and the kickback compensation data. A data driver converts the compensation image data into a data signal and provides the data signal to the pixel.
