Power supply time sequence control circuit and display equipment

The utility model provides a power supply time sequence control circuit and a display device, and belongs to the time sequence control technology. The power supply time sequence control circuit comprises a first power supply module, a first power-down time sequence control module, N second power supply modules, a first power-down detection module, second power-down time sequence control modules corresponding to the second power supply modules, and power-down modules, the power failure detection module is used for detecting whether the first power supply module starts power failure or not and controlling the second power failure time sequence control module to conduct a power failure path of the corresponding power failure module when it is detected that the first power supply module starts power failure, so that the power failure module discharges the second power supply module; the first power-down time sequence control module is used for controlling the power-down speed of the corresponding first power supp
