摘要： 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.

摘要： 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.

摘要： A method of driving an electro wetting display panel includes applying a first data voltage to a pixel part of the display panel during a first section of a frame and applying a second data voltage different from the first data voltage to the same pixel part during a second section of the frame. The first data voltage is converted from display data based on a first gamma curve. The second data voltage is converted from the display data based on a second gamma curve. Light transmittance through the pixel part is changed based on movement of a fluid within the pixel part.
