A display device includes a display panel including gate lines, data lines, and pixels individually connected to a corresponding gate line and data line, a gate driver driving the gate lines, a data driver driving the data lines, and a driving controller. The driving controller receives, from an external source, first image signals and a variable frequency signal indicating an operation frequency (frame rate) for the display device. The driving controller converts the first image signals to second image signals by adding a compensation value corresponding to the operation frequency to the first image signals, and outputs the second image signals to the data driver. Embodiments may compensate for luminance reduction/variation and reduce image artifacts that otherwise occur due to variable frequency operation. An alternative embodiment dynamically controls an amount of light output from a backlight according to the variable frequency signal.

Display device capable of changing luminance depending on operating frequency

A display apparatus includes a timing controller configured to generate a display synchronization signal and a standby enable signal during a moving image mode, wherein the display synchronization signal is generated using an original synchronization signal and the standby enable signal corresponds to a preset frame period of the display synchronization signal. The display apparatus includes a data driver to block a data voltage from being provided to a data line in response to the standby enable signal, and a gate clock generator configured to block a gate clock signal from being outputted in response to the standby enable signal.
