An energy recovery circuit of a display panel and a driving apparatus having the same are provided to perform a stable switching operation by properly aligning diodes and switching elements. An energy recovery circuit of a display panel includes an energy storage unit(421), an energy recovery switching unit(430), and an inductor. The energy storage unit is charged by recovering power from a panel capacitor(Cp). The energy recovery switching unit is connected with the energy storage unit at one end to control charge to the panel capacitor and recovery from the energy storage unit. The inductor is connected with the energy recovery switching unit at one end, and with the panel capacitor at the other end. The energy recovery switching unit comprises first and second control switches(M1,M2), and first and second diodes(Dr,Df). The first and second control switches are connected in parallel between the energy storage unit and the inductor. The first diode is arranged between the first control switch and the inductor to allow current to flow from the first control switch to the inductor. The second diode is arranged between the second control switch and the energy storage unit to allow current to flow from the second control switch to the energy storage unit.
