摘要： A display device is provided. The display device includes a display panel, a gate driver, and a data driver. The display panel includes a plurality of pixels connected to a plurality of gate lines for receiving gate signals, a plurality of data lines for receiving data voltages, and a storage line for receiving a storage voltage. The gate driver is configured to generate the gate signals. The data driver is configured to operate individually in first and second frequency periods to generate the data voltages. The data voltages include a positive data voltage and a negative data voltage, and polarities of the data voltages are inverted every two data lines during the first frequency period and inverted every data line during the second frequency period.

摘要： 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.
