Display device

A display device, comprising:

• a display panel in which a plurality of sub-pixels are arranged in a matrix and are configured to sequentially emit light along rows;
• a driving voltage supply circuit configrued to supply a driving voltage to the display panel;
• a charge storage circuit electrically connected to the driving voltage supply circuit;
• and
• a controller coinfigured to control the driving voltage supply circuit and the charge storage circuit,
• wherein the controller is configured to output a data signal to the charge storage circuit based on a change in a gradation of an image per region of the display panel,
• wherein the charge storage circuit includes a plurality of switches electrically connected to the driving voltage supply circuit, a plurality of capacitors electrically connected respectively to the plurality of switches, and a decoder configured to control the plurality of switches, and
• wherein the plurality of switches are configured to be controlled according to the data signal output from the controller to the charge storage circuit.
