ABSTRACT:
An energy recovery circuit of a display device, which provides a driving voltage to a display panel, is disclosed. The energy recovery circuit includes a first capacitor for charging the voltage recovered from the display panel, a switch circuit connected between the first capacitor and the display panel and having a plurality of switches for switching a current flow when charging/discharging the first capacitor and the display panel, a second capacitor connected between the switches of the switch circuit for discharging the charged voltage to the display panel along with the voltage discharged from the first capacitor when charging the display panel, and a power supply for providing voltage to the first and second capacitors.
