Abstract: A display device includes a voltage generating unit configured to convert an input voltage into an analog driving voltage, a controller configured to receive input image data and an image control signal and generate custom image data and a data control signal, a source driving unit configured to receive the analog driving voltage and convert the custom image data into data voltages in response to the data control signal, a sensing unit configured to sense a load current, wherein the sensing unit is connected to one point on a path through which the input voltage is converted into the analog driving voltage to be provided to the source driving unit, and a display panel configured to receive the data voltages to display an image. The controller receives the sensed load current and generates a selection signal according to a first intensity of the load current.
