ABSTRACT:
A method of operating a display comprising a lattice of pixel elements, includes the step of time-multiplex addressing collections of pixel elements. This addressing step includes using a first shift register means to designate operation of a second shift register means to select a function to be performed. If the second shift register means is in bypass mode, then the first shift register means is effective as a mask to specify which of the stages in the second register means should be bypassed, and allows non-sequential group addressing of the pixel elements. Such an arrangement of first and second shift register means is suitable for use in controlling the addressing of collections or rows of pixel elements; the function to be selected by the second shift register means is the strobing of the collections or rows.
