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.

Abstract: A display panel driving apparatus includes a data processor configured to receive N-th line data of image data. N is a natural number not less than 2. The data processor is further configured to perform a first line delay on the N-th line data to output (N−1)-th line data, to output (N−1)-th line substitution data which is obtained by N-th line substitution data, which is based on the N-th line data and the (N−1)-th line data, and to compensate the N-th line data based on the N-th line data and the (N−1)-th line substitution data to output compensation image data. The display panel driving apparatus further includes a data driver and a gate driver.

Abstract: A display apparatus includes a display panel, a gate driving part, and a data driving part. The display panel is configured to display an image, and includes a gate line and a data line. The gate driving part is configured to output a gate signal to the gate line. The data driving part is configured to output a data signal to the data line. A transition time of the data signal is a time when the data signal transitions from a low level to a high level, and the transition time of the data signal increases according to a decrease of a load of the display panel.
