Disclosed are a backlight driving circuit and a display apparatus. The backlight driving circuit comprises: a switch field-effect transistor (FET) (Q1), a flywheel FET (Q2), a power supply module, a control module, a light-emitting diode (LED) group (Z), and a feedback module. The power supply module is used for supplying power to the LED group (Z), the control module is used for controlling turn-on time of the switch FET (Q1) and turn-on time of the flywheel FET (Q2) to be opposite, and the feedback module is used for providing a feedback voltage to the control module. The display apparatus is provided with a backlight driving module. An FET is used as a flywheel in a backlight driving circuit, power consumption in a driving circuit is effectively reduced, and the efficiency of the driving circuit is improved. |
