    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.

    Abstract translation: 本文公开的主题涉及改善电润湿显示器的亮度和减少颜色偏移。 电润湿显示器包括由分隔壁和间隔物隔开的多个电润湿元件。 间隔物和/或分隔壁是反射性的。 当进入像素或子像素的入射光被反射并遇到间隔物和/或分隔壁时，光被反射，使得反射光离开入射光入射的像素或子像素。 这提高了电泳显示器的亮度并减少了颜色偏移。

    Abstract: An electrowetting display comprises a support plate on which individual electrowetting pixels separated from one another by pixel walls are formed. The individual electrowetting pixels include an electrode layer on the support plate, a dielectric barrier layer on the electrode layer, a hydrophobic layer on the dielectric barrier layer, and quantum dots between the hydrophobic layer and the electrode layer. The quantum dots may utilize blue or white light illuminating the pixels to emit longer-wavelength colors such as red and green. Such a feature may enhance or replace functionality of color filters.

    Abstract: A display device includes a first support plate and an opposing second support plate. At least a portion of a wall on the first support plate is associated with a pixel within a pixel region. The wall has a first segment, a second segment perpendicular to the first segment, and a third segment perpendicular to the first segment and parallel to the second segment. A first spacer on the second support plate extends toward the wall. The first spacer includes a first portion contacting the wall along a length of the first segment, a second portion coupled to the first portion and contacting the second segment along a first portion of the second segment, and a third portion coupled to the first portion and contacting the third segment along a first portion of the third segment.
