A backup architecture for a backlight module comprises a first power system and a second power system, each having an enable mode and a disable mode; and a sensor unit, electrically connected to the first and the second power systems. In the enable mode, the first power system or the second power system is enabled to drive the backlight module to emit light. In the disable mode, the first power system or the second power system is disabled and stops driving the backlight module. The first and the second power systems are interconnected in parallel. When one of the first power system and the second power system enters into the enable mode, the other enters into the disable mode. The sensor unit acquires the working signals of the first and the second power systems and monitors whether the first power system or the second power system is in an abnormal state.
