Display apparatus and a method of driving the same

A method of driving a display device, comprising:

• outputting, from a timing controller, a first gate control signal, a second gate control signal, an image signal, a backlight control signal and a data control signal, wherein the first gate control signal includes a first gate clock and the second gate control signal includes a second gate clock;
• outputting, from a data driver, a data voltage, which corresponds to the image signal, to data lines of a display panel according to the data control signal;
• outputting, from a first gate driver, first gate signals in synchronization with the first gate clock to odd numbered gate lines of the display panel;
• outputting, from a second gate driver, second gate signals in synchronization with the second gate clock to even numbered gate lines of the display panel;
• performing an on-operation of a backlight unit during a high section of the backlight control signal;
• and
• performing an off-operation of the backlight unit during a low section of the backlight control signal,
• wherein the first gate signals and the second gate signals are output with a first pulse width during the high section of the backlight control signal and a second pulse width greater than the first pulse width during the low section of the backlight control signal.

A display device, comprising:

• a display panel including gate lines, data lines crossing the gate lines and a plurality of pixels, wherein the display panel is configured to display an image;
