Abstract: The disclosure relates to a drive control method and assembly, and a display device. A drive control method for a timing controller includes generating a point-to-point configuration instruction including an identity identification of a source driver, wherein the source driver is any of a plurality of source drivers, sending the point-to-point configuration instruction via first signal lines, and receiving a configuration response instruction sent by the source driver via the one of the first signal lines. The configuration response instruction is sent by the source driver after executing the point-to-point configuration instruction in response to detecting that the identity identification in the instruction is its own identity identification.
