Abstract: A display device includes a display panel including a first pixel and a second pixel disposed adjacent to the first pixel along a first direction, a gate driver configured to provide gate signals to the display panel, a data driver configured to provide data signals to the first and second pixels and a driving controller configured to receive an image data, configured to provide a data signal to the data driver based on the image data, and configured to determine whether a white balance of a current image data corresponding to the second pixel is within a set range. The driving controller calculates the data voltage provided to the second pixel based on the white balance of the current image data corresponding to the second pixel, a previous image data corresponding to the first pixel, and the current image data.

Abstract: A power voltage generating circuit includes an input part, a clock determining part and a plurality of switches. The input part receives a plurality of clock signals and generates a plurality of peak signals corresponding to rising edges of the plurality of clock signals. The clock determining part determines a normal mode and an abnormal mode based on a number of the plurality of peak signals. The switches blocks outputs of the plurality of clock signals in the abnormal mode.
