Method of driving data lines, apparatus for driving data lines and display device having the same

摘要

An apparatus for driving a plurality of data lines coupled to a plurality of pixels includes a gray scale voltage selection circuit, a shift register and an output circuit. The gray scale voltage selection circuit selects one of a plurality of gray scale voltage signals based on image data to output the selected gray scale voltage signal. The shift register sequentially generates enable signals in response to a start signal and shifted clock signals. The output circuit sequentially provides the data lines with the selected gray scale voltage signals as data signals in response to the enable signals.
