Abstract
A display device includes: a display panel including pixels arranged in a matrix shape; and a source driver to apply data voltages to the pixels. The source driver includes: a shift controller to shift a sampling control signal; a latch array to sample digital video data in response to the sampling control signal shifted by the shift controller; a digital-to-analog converter array to convert the digital video data from the latch array into data voltages by decoding the digital video data and combination-outputting gamma compensation voltages on the basis of a gray value of the decoded data; an output buffer array to output the data voltages from the digital-to-analog converter array; and a bias controller to adjust a bias current, which is applied to the output buffer array, according to delay and stable intervals of the data voltage.
