DATA TRANSFER DEVICE, DISPLAY DEVICE, DATA TRANSMITTER, DATARECEIVER, AND DATA TRANSFER METHOD

摘要

When data is transferred from a controller of a liquid crystal display devic e to each driver through a predetermined number of signal lines, the Transferring Data are divided into a plurality of groups by forming the signal lines into groups beforehand. For each group , the combination of inversion/non-inversion of the data to be transmitted is examined, a well- balanced combination is selected so as to reduce EMI. Further, a control range is set and, for each group, data inversion is selected according to whether the number of "data to be transmitted" differe nt from "data transmitted immediately therebefore" is in the control range or not.
