Abstract
A display device includes a display panel including a plurality of data lines, and a plurality of pixels coupled to the plurality of data lines, a data driver including a plurality of channels providing data voltages to the plurality of pixels through the plurality of data lines, and a controller configured to control the data driver. The plurality of channels is grouped into first through N-th channel groups, where N is an integer greater than 1. The first through N-th channel groups sequentially initiate first dummy data voltage output operations in a first order from the first channel group to the N-th channel group in a first blank period before an active period, and sequentially finish second dummy data voltage output operations in a second order from the N-th channel group to the first channel group in a second blank period after the active period.
