Abstract: A display apparatus includes a display panel including display blocks, where each of the display blocks includes a plurality of pixels, a gate driver which outputs gate signals to the pixels, a data driver which receives image data and outputs data voltages corresponding to the image data to the pixels, and a timing controller which converts an image signal input thereto, outputs the converted image signal to the data driver as the image data, and controls a driving timing of the gate driver and the data driver. The timing controller controls output timings of at least data voltages output to pixels of a predetermined display block among the data voltages provided to the pixels of the display blocks, depending on a color pattern of the image signal corresponding to the pixels of the predetermined display block.

Abstract: A display apparatus includes a display panel having fan-out lines, data lines, a first dummy line, and a second dummy line. The fan-out lines are sequentially disposed along a first direction. The data lines are connected to the fan-out lines at first through nodes. The first dummy line is connected to one of the nodes. The second dummy line is connected to another of the nodes. A first data driver is configured to output data voltages to some of the fan-out lines based on a data signal. A second data driver is configured to output voltages to other fan-out lines based on the data signal. A timing controller is configured to compensate the data signal based on a voltage of nodes that the dummy lines are connected to.
