More Information
Summary:A display device can include a display panel having a plurality of pixels disposed on a substrate, and a power supplier configured to supply a driving voltage to the display panel. The power supplier can include a first converter configured to receive an input voltage supplied from an external system and convert the input voltage into a boost voltage, a second converter configured to convert the boost voltage into the driving voltage, a first feedback unit configured to output a first pulse width modulation (PWM) signal to the first converter so that the boost voltage is proportional to a first reference voltage, and a second feedback unit configured to output a second PWM signal to the second converter so that the driving voltage is proportional to a second reference voltage.
