A display apparatus includes a display panel including a switching element connected to a data line and a gate line, a pixel electrode connected to the switching element, a common electrode facing the pixel electrode and a liquid crystal layer disposed between the pixel electrode and the common electrode. The display apparatus further includes a data driving circuit configured to convert image data to a data voltage. The display apparatus further includes a driving voltage generator configured to generate a common voltage, in response to a voltage control signal from a timing controller, to the common electrode and the data driving circuit, which is configured to output the common voltage to the pixel electrode during an initial setting period when power is turned on to the display apparatus.

Display apparatus with reduced flash noise, and a method of driving the display apparatus

A display device includes a liquid crystal display and a power supply to apply a common voltage to a common electrode of the display. The power supply applies a first common voltage to the common electrode for a first period after power is turned on, and applies a second common voltage higher than the first common voltage to the common electrode until the power is turned off after the first period.
