  • 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: 10101596
    Abstract: An eye patch formed of a flexible, opaque material is attached to a pair of eyeglasses. The patch has an asymmetric conical shape when in repose. The patch extends from an eyeglass nose bridge around a ninety degree (90°) bend to an eyeglass temple piece and overlies a lens of the eyeglasses. At least one slit is formed in an outboard end of the patch to slidingly receive the eyeglass temple piece. An elastic strap is secured to a peripheral boundary of the patch at the inboard end of the patch. The elastic strap underlies the nose bridge so that the elastic strap captures the nose bridge. The peripheral boundary of the patch abuts a user's face in encircling relation to an eye when the patch is secured to the eyeglasses so that light is prevented from reaching the eye.

  • Patent number: 10088729
    Abstract: Conventional electrochromic devices frequently suffer from poor reliability and poor performance. Improvements are made using entirely solid and inorganic materials. Electrochromic devices are fabricated by forming an ion conducting electronically insulating interfacial region that serves as an IC layer. In some methods, the interfacial region is formed after formation of an electrochromic and a counter electrode layer, which are in direct contact with one another. The interfacial region contains an ion conducting electronically insulating material along with components of the electrochromic and/or the counter electrode layer. Materials and microstructure of the electrochromic devices provide improvements in performance and reliability over conventional devices. In addition to the improved electrochromic devices and methods for fabrication, integrated deposition systems for forming such improved devices are also disclosed.
