Abstract: A display apparatus includes a timing controller, a common voltage generator, a data driver, and a display panel. The timing controller determines a representative grayscale of each frame based on input image data and generates a common voltage control signal having a first digital value ratio (“DVR”) value corresponding to a first frame, a representative grayscale of the first frame being included in a first grayscale range. The common voltage generator generates a first common voltage based on the common voltage control signal. The data driver generates a data voltage based on the input image data. The display panel displays an image corresponding to the first frame based on the data voltage and the first common voltage.

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.

Abstract: A display apparatus includes a display panel, a gate driving part, and a data driving part. The display panel is configured to display an image, and includes a gate line and a data line. The gate driving part is configured to output a gate signal to the gate line. The data driving part is configured to output a data signal to the data line. A transition time of the data signal is a time when the data signal transitions from a low level to a high level, and the transition time of the data signal increases according to a decrease of a load of the display panel.
