Abstract: A method of obtaining overdriving data includes providing a first data voltage corresponding to a current line reference gray level to a second pixel for first and second data writing times for first and second pixels in a first frame, measuring first luminance based on the first data voltage, applying a second data voltage corresponding to a previous line reference gray level for the first data writing time in a second frame, providing a third data voltage of an overdriving voltage corresponding to a predicted overdriving gray level added to the first data voltage for the second data writing time in the second frame, measuring second luminance based on the third data voltage, and determining an overdriving value corresponding to a reference gray level pair of the current and the previous line reference gray level as the predicted overdriving gray level when the first and second luminance are the same.

Abstract: A display device may include a display panel including a plurality of pixels, a data driver which applies data signals to the display panel, a scan driver including scan stages, which sequentially applies scan signals to the display panel, an emission driver including an emission stage which sequentially applies emission signals to the display panel, and a power supply voltage generator which generates a power supply voltage including high voltages and low voltages, and provides the high voltages having different voltage levels from each other or the low voltages having different voltage levels from each other to at least one selected from the scan stages and the emission stage. The power supply voltage generator generates a first high voltage, a first low voltage, a second high voltage lower than the first high voltage, and a second low voltage higher than the first low voltage based on an input voltage.

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.
