    Abstract: A display device includes a display panel including a plurality of pixels, a controller for providing a clock-embedded data signal including image data in an active period and including a training pattern in a blank period, and a data driver for recovering the image data from the clock-embedded data signal based on an internal clock signal to provide data voltages corresponding to the image data to the plurality of pixels in the active period, and to perform a training operation for the internal clock signal using the training pattern included in the clock-embedded data signal in the blank period. The training pattern in the blank period includes a first training clock signal modulated with a first modulation period during a first time, and includes a second training clock signal modulated with a second modulation period different from the first modulation period after the first time.

    Abstract: Provided is a data driver including a digital to analog converter configured to convert image signal data into a plurality of data voltages, and an output buffer unit including a plurality of channels for outputting the plurality of data voltages. The output buffer unit includes a plurality of output blocks. Each output block includes one or more channels. Data voltages outputted from a first output block among the plurality of output blocks are delayed with a first time difference. Data voltages outputted from a second output block among the plurality of output blocks are delayed with a second time difference which is different from the first time difference.
