1. A display apparatus, comprising:
a display screen configured to display an image;
at least one Light Emitting Diode (LED) light bar configured to provide light to the display screen; and
a power supply circuit configured to supply power to the display apparatus;
wherein the power supply circuit comprises a resonant converter (LLC) primary winding, a first LLC secondary winding and a second LLC secondary winding, wherein the first LLC secondary winding is configured to convert a voltage of the LLC primary winding into a first voltage, the second LLC secondary winding is configured to convert the voltage of the LLC primary winding into a second voltage; and
the power supply circuit is configured to adjust the first voltage output from the first LLC secondary winding into a third voltage, and supply power to the at least one LED light bar through a sum of the third voltage and the second voltage.
