Abstract: A display device includes a timing controller which supplies a clock training signal through a data clock signal line and a first control signal through a shared signal line in a first period of one frame, and supplies image data through the data clock signal line in a second period of the one frame, a data driver provided with data driving circuits which generate a clock signal based on the clock training signal and the first control signal in the first period, and generate data voltages based on the clock signal and the image data in the second period, and a pixel part which receives the data voltages from the data driver. The data driver may supply a second control signal indicating a reception state of the data driver to the timing controller through the shared signal line in the second period.

Abstract: A display device includes a display panel and the display panel includes a pixel. The pixel includes a light emitting unit including at least one light emitting element, a driving transistor providing a driving current corresponding to a data signal to the light emitting unit, and a first transistor electrically connected between both ends of the light emitting unit. A driver provides the data signal to the pixel and provides a duty control signal to the first transistor. The driver varies a voltage level of the data signal in a first grayscale section in which a grayscale corresponding to the data signal is greater than or equal to a reference grayscale, and varies a duty ratio of the duty control signal in a second grayscale section in which the grayscale is less than the reference grayscale.
