1. A projection display synchronization control system, comprising:

  • the system comprises a data decoding module, a master control module, a master spatial light modulator driving module, a slave spatial light modulator driving module and a light source driving module;

    the data decoding module is used for receiving and decoding source data to generate N-primary color data and sending the N-primary color data to the main control module, wherein the N-primary color data comprises an automatic synchronization signal, and N is a positive integer;

    the main control module is used for receiving and dividing the N-primary color data into two data blocks at least comprising a first data block and a second data block, and sending the first data block to the main spatial light modulator driving module and the second data block to the slave spatial light modulator driving module;

    the main spatial light modulator driving module is used for receiving the first data block and sending a driving signal to the corresponding spatial light modulator so as to drive the spatial light modulator to work;

    the slave spatial light modulator driving module is used for receiving the second data block and sending a driving signal to the corresponding spatial light modulator so as to drive the spatial light modulator to work;

    the light source driving module is used for receiving a light source driving signal sent by at least one of the main control module, the main spatial light modulator driving module and the slave spatial light modulator driving module and driving a light source;

    and the slave spatial light modulator driving module receives the synchronous signal of the master spatial light modulator driving module and synchronously drives the corresponding spatial light modulator.
