Abstract:
A display device includes: a pixel unit including pixels connected to data lines and scan lines, and signal output lines, where at least one signal output line of the signal output lines is connected to each of the scan lines through a contact point; a data driver disposed at one side of the pixel unit to drive the data lines; a scan driver disposed at the one side of the pixel unit together with the data driver to drive the scan lines; and a timing controller controlling the data driver and the scan driver. The data driver includes: output buffers outputting data signals to the data lines, respectively; and a slew rate controller adjusting a slew rate of the data signals by controlling a bias value supplied to the output buffers in units of pixel rows based on positions of the pixels and a change in the data signals.
