    摘要： A display device and a method of driving the same are described. The display device includes: an over driver to overdrive current frame data included in input image data to output overdriving frame data; a data driver to generate a data signal for the current frame data based on the overdriving frame data; and a display panel including a plurality of pixels to receive the data signal, the over driver may calculate a temporal change rate or a spatial change rate of the input image data, and output the overdriving frame data utilizing a reference formula having a first main parameter determined according to the calculated result. Therefore, overdriving may be performed dynamically according to the spatial change rate or the temporal change rate of the input image data.

    摘要： A power voltage generator includes a booster, a voltage sensor, a constant voltage controller and a constant current controller. The booster is configured to boost an input voltage to an output voltage based on an on-off operation of a switch. The voltage sensor is configured to generate a sensing voltage by sensing the output voltage. The constant voltage controller is configured to generate a first switching signal to control the switch by comparing the sensing voltage with a reference voltage. The constant current controller is configured to generate a gain based on a ratio of an electrode signal of the switch and a target signal by comparing the electrode signal of the switch with the target signal.
