Patent ID: 7161609

Claim:
A multiple-bit storage element for a binary optical display element comprising: a plurality of circularly interconnected bit storage cells to store a number of bits of a color intensity value to be displayed by the binary optical display element during a display period, a last storage cell storing a bit to be displayed next by the binary optical display element; a load line that is asserted to shift bits stored by a first bit storage cell through a second-from-last bit storage cell to a second bit storage cell through the last bit storage cell and to load a next bit of the number of bits of the color intensity value into a first bit storage cell; and, a rotate line that is asserted to shift the bits stored by the first bit storage cell through the second-from-last bit storage cell to the second bit storage cell through the last bit storage cell and to shift a bit stored by the last bit storage cell to the first bit storage cell.
