  • Patent number: 10120184
    Abstract: Subject matter disclosed herein relates to improving luminance and reducing color shifts in electrowetting displays. The electrowetting display comprises a plurality of electrowetting elements separated by partition walls and spacers. The spacers and/or partition walls are reflective. When incident light that enters a pixel or subpixel is reflected and encounters a spacer and/or partition wall, the light is reflected such that the reflected light exits the pixel or subpixel into which the incident light entered. This improves luminance and reduces color shifts of the electrowetting display.

  • Patent number: 10078213
    Abstract: A method for fabricating an electrowetting display may include depositing a sacrificial layer on a support plate, etching portions of the sacrificial layer to form liquid duct forms on the support plate, depositing a photoresist layer on the liquid duct forms and the support plate, etching portions of the photoresist layer to form a spacer grid, and removing the liquid duct forms to form liquid ducts between the support plate and the portions of the spacer grid.

  • Patent number: 9910264
    Abstract: Subject matter disclosed herein relates to arrangements and techniques that provide for improving contact between spacers of a first substrate of an electrowetting display device and pixel walls of a second substrate of the electrowetting display device by providing an adhesive between the spacers and the pixel walls. An electrowetting display device comprises a first substrate including a plurality of pixel walls and a second substrate including a plurality of spacers. A first fluid is disposed between the first substrate and the second substrate within the pixel walls. A second fluid is disposed on the first fluid, wherein the first fluid is immiscible with the second fluid. An adhesive couples the spacers to the pixel walls.

  • Patent number: 9547168
    Abstract: The subject matter disclosed herein relates to an electrowetting display comprising: a dielectric barrier layer formed on a substrate; a hydrophobic layer formed on the dielectric barrier layer, wherein the dielectric barrier layer maintains a separation between the hydrophobic layer and the substrate; a patterned pixel grid formed on the hydrophobic layer, wherein the patterned pixel grid comprises rows and columns of pixel walls that form field pixels and border pixels; an oil film overlying the hydrophobic layer, wherein the oil film is partitioned by the patterned pixel grid; and an electrolyte overlying the oil film and the patterned pixel grid, wherein one or more of the rows or the columns of pixel walls of the patterned pixel grid includes a substantially nonlinear-shaped portion to reduce sheer stress between the patterned pixel grid and the hydrophobic layer.
