Abstract: The invention provides a display driving system having a master chip and a plurality of slave chips. The master chip marks a serial number of the storage unit buffering the display data of the corresponding region of an image frame in the N storage units when using the connected memory to buffer the display data of the corresponding region; when reading the display data of the corresponding region stored in a storage unit, marks the serial number of the read storage unit, generating a corresponding synchronization signal to transmit to each slave chip to control the display data of an image frame to be buffered synchronously to storage units of the same serial number in the plurality of memories, and control the master/slave chips to synchronously read respectively the display data of the image frame from the storage units with the same serial number in the connected memory.
