Abstract:
A display driver for driving an nNxM or MxnN thin-film transistor liquid-crystal display, comprising:a first shift register providing N graded sample clocks;a sample and hold circuit including N processing units controlled by said N graded sample clocks from said first shift register to sample and hold input video signals in groups of N pixels per cycle;a group block having n groups, each of the n groups including N switches for receiving N pixels per cycle from said sample and hold circuit and including a control line to collectively control the N switches of the group; anda controller controlling said first shift register to provide the N graded sample clocks, controlling said sample and hold circuit to output N video signals per cycle and controlling said group block via the n control lines to redirect the N pixel signals to one of said n groups per cycle to output nN pixel signals to a display panel after n cycles.
