ABSTRACT:
A driving circuit for a simple matrix type display apparatus in which an input data signal is stored in a frame buffer and subjected to orthogonal transformation, whereby a display is performed, includes: a plurality of line buffers whose number is equal to the number of scanning lines to be selected in accordance with a multiple-scanning line simultaneous selection method, respectively having a region I and a region II, wherein while one of the regions I and II is used for writing, the other is used for reading; and a frame buffer which allows data from the plurality of line buffers to be written during a plurality of horizontal non-display periods and all of the selected scanning lines of data to be written at a time, wherein the number of the plurality of line buffers is equal to the number of the selected scanning lines.
