The present application discloses a register value transmission method and component, and a display device, and belongs to the field of display manufacture. The method is used for a timing sequence controller, and comprises receiving a user-triggered information setting instruction, wherein the information setting instruction includes n register values for instructing a source driving chip to setthe configuration information of the source driving chip based on the n register values, and n is greater than 1; according to the information setting instruction, generating an information setting command including the n register values; and transmitting the information setting command to the source driving chip. The method solves the low matching flexibility of the number of register values at both a receiving end and a transmitting end, and improves the matching flexibility of the number of register values, and is used for the display device.
