ABSTRACT:
To reduce both frequency of the source driver and the capacity of memory used for this purpose. An apparatus for supplying data to a plurality of source drivers classified into a plurality of groups each of the source drivers driving a part of a LCD panel, comprising: a plurality of memory blocks, each block supplying data to one of the groups of the source driver and allowing itself to be read out and be written into simultaneously; control circuits for switching the memory blocks to be written when data of pixels drawn by one source driver when one line in the LCD panel is drawn written from the frame buffer into one memory block; and wherein while writing data into the memory block, the written data is read from the memory block at a lower speed than the writing, simultaneously.
