Abstract

A display device includes a plurality of data lines, a plurality of first gate lines, a plurality of second gate lines, and a plurality of pixels. The plurality of pixels includes a first group of pixels and a second group of pixels. The plurality of data lines includes a first group of data lines connected to the first group of pixels and a second group of data lines connected to the second group of pixels. A data signal is provided to the first group of pixels in a first sub-frame period of one frame period. A data signal is provided to the second group pixels in a second sub-frame period of the one frame period that is adjacent to the first sub-frame period.
