Abstract: A display apparatus includes a display panel configured to display an image, a data driver including a voltage generator configured to convert an image data applied thereto to a data voltage and a buffer configured to apply the data voltage to the display panel, a timing controller including a mode controller configured to generate a mode selection signal on the basis of an image frame rate of the image data. The data driver is configured to be operated in a power cut-off mode or a stand-by mode in response to the mode selection signal. The driving voltage switch is configured to cut off the analog driving voltage applied to at least one of the buffer and the voltage generator during the power cut-off mode and the bias controller is configured to reduce a bias current in the stand-by mode.
