Abstract:
A display device may include a display panel which displays an image based on a data voltage, a driving controller including a net power control setter which determines a scale factor for adjusting a gray scale of (N+1)th frame data based on a load of Nth frame data and a net power control reference value, where the driving controller generates a data signal based on input image data, and N is a natural number greater than or equal to 2, a data driver which converts the data signal into the data voltage and outputs the data voltage to the display panel, and a power supply voltage generator which senses a power supply current applied to the display panel in an Nth frame and generates a power supply voltage based on a current level of the power supply current.
