  • Patent number: 9759975
    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. 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 various embodiments, a counter electrode is fabricated to include a base anodically coloring material and one or more additives.

  • Publication number: 20150146276
    Abstract: The present invention relates to a switchable infrared ray-visible ray reflection electrochemical mirror having high electrochemical stability and bistability, in which a stripping phenomenon of a metal thin film can be prevented and bistability can be improved through a process of increasing electrochemical stability of a reflective film from an electrode composition and an ionic liquid electrolyte composition having various compositions. In the proposed electrochemical mirror apparatus, since the metal thin film formed by electric reduction is not stripped from a transparent electrode through a surface treatment process, a more stable apparatus can be provided, and even though a voltage is not applied to the metal thin film, the thin film is prevented from being oxidized by using an optimized ionic liquid electrolyte, thus providing the effective electrochemical mirror apparatus where the metal thin film is continuously maintained.

  • Patent number: 8693078
    Abstract: This invention contemplates integrating laser scribing/patterning the component layers of electrochromic devices by directly removing (ablating) the material of the component layers. To minimize redeposition of laser ablated material and particulate formation on device surfaces a number of approaches may be used: (1) ablated material generated by the focused laser patterning may be removed by vacuum suction and/or application of an inert gas jet in the vicinity of the laser ablation of device material; (2) spatial separation of the edges of layers and patterning of lower layers prior to deposition of upper layers; and (3) the laser patterning step may be performed by a laser beam focused directly on the deposited layers from above, by a laser beam directed through the transparent substrate, or by a combination of both.

  • Patent number: 8687262
    Abstract: An ion conductor includes a mixture including an electrolyte including a salt including inorganic or organic pairs of negative and positive ions, and a low-molecular liquid crystal material. Further, an impedance of the ion conductor varies in accordance with an increase of a voltage applied to the ion conductor due to an orientation response of the low-molecular liquid crystal material, the impedance being determined by an AC impedance method.

  • Patent number: 8686988
    Abstract: In the case of depositing a metal in a plurality of stages by applying deposition voltages having a plurality of rectangular waves at different voltages to an electrochemical display element, the application time of the rectangular wave at the highest voltage among the plurality of rectangular waves is set to a time (Tip) required for reaching a resistance inflexion point (Rip) where the resistance value (R) of a pixel starts to rapidly increase or shorter. Thus, the element can be prevented from being broken without deteriorating the response characteristics of a display element.
