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. The second electric potential is imposed on the first non-pixel region.
