Abstract: A display device includes a timing controller configured to receive an image data signal and a plurality of clock signals and to generate a scan clock signal and a plurality of data clock signals, a scan driver configured to receive the scan clock signal, and a data driver configured to receive the data clock signals. The clock signals include first to nth clock signals, and the data clock signals include first to nth data clock signals generated from the first to nth clock signals (n≧2), the first to nth clock signals having differing frequencies and the first to nth data clock signals having differing frequencies. Whenever a predetermined number of frame periods has elapsed, the timing controller halts transmission of one of the first to nth data clock signals to the data driver, and begins transmission of another one of the first to nth data clock signals thereto.

Abstract: A display device includes at least one device performing a display function and a power supply unit which supplies power to the device and determines whether a malfunction of the device occurred, stops supplying power to the device during a preset power supply stop period when a malfunction of the device occurred and resumes supplying power to the device after the preset power supply stop period.

Abstract: A display device includes a display unit including a plurality of pixels for displaying images, a scan driver which supplies scan signals to the plurality of pixels, a data driver which supplies data signals to the plurality of pixels, a communication module which measures a reception rate of communication signals received through an antenna, a processor which compares the reception rate with a reference reception rate and generating a driving voltage control signal, based on a determination result, and a power supply which generates a first driving voltage to be supplied to each of the scan driver and the data driver where the power supply changes at least one of a first slew rate and a first frequency of the first driving voltage, based on the driving voltage control signal, thereby generating a second driving voltage having at least one of a second slew rate and a second frequency.
