Single-path and double-path compatible screen driving method and system

The invention discloses a screen driving method and system compatible with a single path and a double path, and the system comprises a serializer which is connected with a first deserializer through a differential converter, is directly connected with a second deserializer, and is used for outputting a first group of LVDS video signals in two groups of LVDS video signals to the differential converter, and outputting a second group of LVDS video signals in two groups of LVDS video signals to the differential converter; the second group of LVDS video signals in the two groups of LVDS video signals is output to the second deserializer; the differential converter is used for controlling a transmission path of the first group of LVDS video signals so as to transmit the first group of LVDS video signals to the first deserializer for analysis or transmit the first group of LVDS video signals to the second deserializer for analysis; the first deserializer is connected with the first display screen and is used for rec
