Abstract

A display driver circuit for reducing system interface bandwidth requirements and peak current requirements includes a select line sequencer, for providing a series of select line addresses on an address terminal set, and a select line decoder coupled to the address terminal set, for decoding each of the select line addresses and asserting an update signal on a corresponding one of a plurality of output terminals. Optionally, the select line sequencer generates a series of select sub-line addresses, and the select line decoder is a select sub-line decoder.
An optional select address register receives initial select addresses from a system and provides the initial select addresses to the select line sequencer. An alternate display driver circuit including a select line sequencer and a seledct sub-line sequencer is also described.
