The display panel includes sub-pixels. A driver converts first frame data corresponding to a first pixel arrangement of the sub-pixels into second frame data corresponding to a second pixel arrangement and provides data signals corresponding to second frame data to the sub-pixels having the second pixel arrangement. The driver includes a padding circuit and a rendering circuit. The padding circuit converts the first frame data into padding data by adding a padding value to at least one of a front end and a rear end of each line data of the first frame data. The rendering circuit generates the second frame data by applying a rendering filter to the padding data. ## Claims ### Claim 1 A display device comprising: a display panel including pixels and each the pixels including sub-pixels;
