Data transfer method, display driving circuit using the method, and image display apparatus

摘要

A data transfer method for transferring data to an information-side driver for driving a display apparatus is provided. Wherein, driver circuits each comprising a chip address/video data discrimination circuit and a unit driver are mounted around said display apparatus. A unique chip address is set for each of the unit drivers by means of a hardware pattern. Data exchange with the driver circuits is performed so that chip address information and video data information are time-divisionally transferred to the target unit driver using a chip address/video data common bus line and a chip address/video data discrimination control signal.
