A display driver circuit includes a word line sequencer for providing a series of row addresses, and a row decoder for decoding each of the row addresses and asserting write signals on corresponding ones of a plurality of output terminals. An optional data path sequencer provides a series of path addresses which are used by an optional data router to route data to particular sub-rows of a display. Additionally, an optional sub-row sequencer provides a series of sub-row addresses to an optional sub-row decoder, which decodes each of the sub-row addresses and asserts write signals on corresponding ones of a second plurality of output terminals. In various embodiments, the row sequencer, the sub-row sequencer, and/or the data path sequencer is/are responsive to data load instructions from a system, such that no Array Write commands are required to write data to a display.
A display driver circuit for receiving data and data load instructions from a system, and for driving a display having a plurality of data input lines and a first plurality of word lines, each word line being associated with a portion of said display, such that write signals asserted on said word lines cause data asserted on said data input lines to be loaded into said associated portions of said display, said display driver circuit comprising:
