Abstract
A display device includes a display panel which displays an image, and a control circuit board connected to the display panel. The control circuit board includes a controller which analyzes the image in real time and determines in real time a digital-type power voltage based on the image, and a voltage generator which generates an analog-type power voltage based on the digital-type power voltage received from the controller. The voltage generator includes a digital-analog converter which converts the digital-type power voltage into the analog-type power voltage and outputs the analog-type power voltage.
