Display device and electronic device including the same

A display device comprising:

• a display panel including pixels;
• a gate driving circuit which provides a gate signal to the display panel;
• a data driving circuit which provides a data signal to the display panel;
• a driving voltage supplying circuit which supplies a gate driving voltage to the gate driving circuit, supplies a data driving voltage to the data driving circuit, and supplies a panel driving voltage including a first power supply voltage and a second power supply voltage lower than the first power supply voltage to the display panel;
• and
• a driving control circuit which controls the gate driving circuit, the data driving circuit, and the driving voltage supplying circuit,
• wherein the driving control circuit determines a scale factor based on a load of input frame data, generates output frame data by applying the scale factor to the input frame data, and determines the first power supply voltage and an input power supply voltage for generating the first power supply voltage based on a maximum grayscale of the input frame data and a load of the output frame data.
