IMAGE FORMING DEVICE AND CONTROL METHOD THEREFOR AND IMAGE DISPLAY DEVICE AND METHOD

摘要

PROBLEM TO BE SOLVED: To enable a great number of display data to be transferred to driving parts at high speed without increasing the number of transmission lines. SOLUTION: An inputted image signal is converted into digital data in an A/D converting part 5 and supplied to a packet generating part 6. The packet generating part 6 constructs packets affixed with identification information for every driving part and transmits the packets to a common transmission line. Then, packet decoding parts 2-3 of respective driving parts decode respectively only packets addressed to themselves to drive element groups allotted to themselves.
