Abstract
A display device and a method of driving the same are disclosed. In one aspect, the display device includes a gamma generator configured to generate emission duty data having an emission duty period based on input image data, a panel load calculator configured to calculate a load of the display panel, and a target driving voltage determiner configured to determine a target driving voltage. The display device also includes an emission duty controller configured to adjust the emission duty period and determine a target global current, driver configured to drive the display panel, and a driving voltage generator configured to supply the driving voltage to the display panel, measure driving currents flowing into the display panel, and adjust the driving voltage to include the target driving voltage based on the difference between the sum of the measured driving currents and the target global current.
