Multi-path power supply display system, control method and display equipment

The invention provides a multi-path power supply display system, a control method and display equipment. The multi-path power supply display system comprises a data control chip, N paths of cascade modules and N pull-up resistors, each path of cascade module comprises M driving units which are sequentially connected in series and correspondingly controlled LED units; the input end of the first driving unit is coupled to the output end of the data control chip, the output end of the Mth driving unit is coupled to the input end of the data control chip, and each driving unit is coupled to a first power supply voltage; wherein each driving unit is integrated with a CMOS output structure and an open-drain output structure; the data control chip is used for controlling each driving unit in the corresponding cascade module to be switched between the CMOS output structure and the open-drain output structure; each pull-up resistor corresponds to one path of cascade module and is coupled between the output end of the
