Display controller for a flat display apparatus

摘要

A display controller of a flat display apparatus which performs multiple color display and variable color display for display data read out of a lookup table. The lookup table comprises a parallel lookup table which has n (n>/=2) registers for storing color information and m selectors which receive n pieces of color information independently from the n registers, each select one of n pieces of color information, and deliver m pieces of color information simultaneously. The controller further comprises a data selector which selectively delivers the output of other register in the parallel lookup table in place of the register which has been made the read access.
