Abstract
A display apparatus and a compensation circuit are provided. The display apparatus includes a display screen, a sound reproduction device and a power supply circuit. The power supply circuit includes a rectifier circuit and a compensation circuit. The rectifier circuit is used to convert an alternating current to a direct current. The compensation circuit is used to compensate for a parasitic signal of a synchronous rectification MOSFET in the rectifier circuit, thereby reducing heat generated by the MOSFET.
