  • Patent number: 8111444
    Abstract: An imaging method includes emitting radiation from an illumination source towards a total internal reflection (TIR) modulator. At least one of the pixel regions is controlled to form at least one image pixel on a surface. A first electric potential is imposed on a first pixel region, the first electric potential being associated with a first signal provided by a first electrical conductor to the second set of electrodes associated with the first pixel region, the first electrical conductor extending over a first non-pixel region. A second electric potential is imposed on the first pixel region, the second electric potential being associated with a second signal provided by a second electrical conductor to first set of electrodes associated with the first pixel region, the second electrical conductor extending over a second non-pixel region, wherein the second non-pixel region is different from the first non-pixel region, and the second electric potential is different from the first electric potential.

  • Publication number: 20110235149
    Abstract: A total internal reflection (TIR) modulator includes a member comprising an electro-optic material; a plurality of first electrode sets; a plurality of second electrode sets; and a first set of electrical conductors, each electrical conductor in the first set of electrical conductors being coupled to one of the second electrode sets wherein the electrodes in each second electrode set are arranged in an interdigitated relationship with the electrodes in one of the first electrode sets; and each of the first electrode sets comprises a first electrode, the first electrodes being arranged in an interdigitated relationship with the electrical conductors in the first set of electrical conductors.
