Display apparatus and driving method thereof

摘要

A display apparatus and driving method is provided. The display apparatus includes a power supply unit which supplies a DC voltage, a switch unit which is connected to the power supply unit in series and performs a switching operation according to different switching signals, a transformer unit which switches a voltage applied to primary winding to secondary winding according to the switching operation of the switch unit, a synchronous rectifying unit which performs synchronous rectification with respect to the voltage induced to the secondary winding, and an output unit which outputs the rectified DC voltage.
