    Abstract: A display device includes a display panel, a first timing controller, and a second timing controller. The display panel includes a first block and a second block adjacent to the first block, with a data line positioned between the first block and the second block. The first block includes a first column of pixels, and the second block includes a second column of pixels. The first and second columns of pixels are alternately connected to the data line. The first timing controller is configured to receive first image data corresponding to the first block. A second timing controller is configured to receive second image data corresponding to the second block. The first timing controller is configured to transfer at least part of the first mage data to the second timing controller.

    Abstract: A display panel driving apparatus includes a data processing part. The data processing part calculates a first pretilt value of previous image data to output a first pretilt signal, calculates a second pretilt value of current image data to output a second pretilt signal, analyze a luminance distribution of unit pixels from image data to output luminance distribution analysis data, analyzes a color pixel to which a pretilt is applied based on the unit pixel from the image data to output color analysis data, outputs a determination signal indicating whether the pretilt is applied to the image data, according to the luminance distribution analysis data and the color analysis data, and outputs pretilt compensation image data according to the first pretilt signal, the second pretilt signal and the determination signal, as compensation image data.
