Abstract: A display apparatus includes a display panel, a gate driver and a data driver. The display panel includes gate lines, data lines and pixels electrically connected to the gate lines and the data lines. The gate driver is disposed adjacent to a first side of the display panel, and outputs a gate signal to the gate line. The data driver is disposed adjacent to the first side of the display panel, and outputs a data voltage to the data line. A gate signal applied to a position having a low resistance-capacitance (“RC”) delay of the gate line has a kickback slice greater than a kickback slice of a gate signal applied to a position having a high RC delay of the gate line. The kickback slice is defined as a portion having a level lower than a gate-on voltage level in a gate pulse of the gate signal.

Abstract: In a method of operating a display panel, a plurality of data lines are divided into a first data line group through an N-th data line group, where N is a natural number equal to or greater than two. Each of the first through N-th data line groups includes at least two data lines. The first through N-th data line groups are sequentially driven by applying first data voltages through N-th data voltages to the first through N-th data line groups, respectively at different times. A first number of data lines in the first data line group is variable.
