Abstract: A display apparatus includes a display panel including a first pixel configured to include first and second sub-pixels and a second pixel configured to include third and fourth sub-pixels. A timing controller generates pixel data including first and second pixel data respectively corresponding to the first and second pixels and representable in a second matrix space, from pixel signals including first and second pixel signals representable in a first matrix space to respectively correspond to the first and second pixels. The timing controller generates the second pixel data on the basis of the first pixel signal adjacent to the second pixel signal which correspond to each second pixel data in the column direction in the first matrix space.

Abstract: A display apparatus includes gate lines extending in a first direction, data lines extending in a second direction crossing the first direction, first color pixels, and second color pixels. A first color pixel arranged in an f-th column between an f-th data line and an (f+1)th data line is connected to one of the f-th data line and the (f+1)th data line. A first color pixel arranged in a g-th column between a g-th data line and a (g+1)th data line is connected to one of a (g−1)th data line and a (g+2)th data line. First color pixels in a first color pixel diagonal group receive data voltages having a same polarity.Second color pixels in a second color pixel diagonal group receive data voltages having a same polarity.
