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: A display apparatus includes a timing controller and a display panel. The timing controller generates first and second image data based on input image data and generates output image data based on the first and second image data. The first image data corresponds to a boundary region in a first image. The second image data corresponds to a non-boundary region in the first image. The display panel includes a plurality of pixels and displays the first image based on the output image data. The plurality of pixels include boundary pixels corresponding to the boundary region and non-boundary pixels corresponding to the non-boundary region. The boundary pixels operate based on a reference gamma curve. The non-boundary pixels operate based on first and second gamma curves different from the reference gamma curve.

Abstract: A data driver includes a digital-to-analog converter, a control signal output circuit, and an output buffer. The digital-to-analog converter generates first data voltages and second data voltages based on image data and a polarity control signal. Each first data voltage has a positive polarity, and each second data voltage has a negative polarity. The control signal output circuit outputs a first output control signal and a second output control signal based on the polarity control signal. A phase of the second output control signal is different from a phase of the first output control signal. The output buffer outputs the first data voltages based on the first output control signal and outputs the second data voltages based on the second output control signal.
