Abstract: An optical grating phase modulator for a laser interference photoetching system is composed of a substrate, an optical grating, an electric motor and an optical grating positioner. The optical grating, the electric motor and the optical grating positioner are all mounted on the substrate. The optical grating is circular or rectangular, and adopt transmission or reflection type optical grating.

Abstract: Instead of using a clear or a semi-transparent notch within an electrowetting display, a colored notch that is the same color of the pixel region extends from one of the pixel walls toward an opposing pixel wall of the pixel region. The colored notches follow a non-flipped arrangement within each of the pixel regions. For example, each colored notch is adjacent to the same respective pixel wall for a pixel region. In other configurations, the colored notches follow a flipped arrangement within each of the pixel regions. For example, a colored notch of one pixel region and a colored notch of another pixel region are adjacent to the same pixel wall (on opposing sides). Instead of including a separate white sub pixel for each pixel, each pixel region is at least partially covered by a white color filter and a color filter that is the color of the pixel.
