Abstract: A display apparatus includes a display panel including a plurality of pixels, a gate driver which applies a bias gate signal to the pixels, a data driver which applies a data voltage to the pixels, an emission driver which applies an emission signal to the pixels, and a driving controller which controls the gate driver, the data driver, and the emission driver. The driving controller calculates a grayscale change region of input image data and a grayscale change level of the grayscale change region, determines a compensation region of the input image data based on the grayscale change region, determines a compensation grayscale voltage based on the grayscale change level, and compensates for the compensation region of the input image data based on the compensation grayscale voltage to generate output image data.

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.
