  • Patent number: 10989968
    Abstract: An optical element configured to allow an image beam passing through is provided. The optical element includes a first and a second birefringent layer and a gas layer between the first and the second birefringent layer. An extension direction of the gas layer is inclined with respect to an extension direction of the optical element, wherein the image beam passes through the first birefringent layer, the gas layer and the second birefringent layer in sequence. A first and a second sub image beam having different deflection angles are generated from the image beam when the image beam enters the gas layer. After the first and the second sub image beam are emitted from the second birefringent layer, a transmission path of the first and the second sub image beam are offset from each other by an offset distance, thereby improving resolution of an image to be viewed.

  • Patent number: 10663833
    Abstract: In accordance with a version of the invention, graphene with a ferroelectric material is used as the transparent electrode material in an electrochromic device. The use of curved and dynamically flexing substrates enables flexible and stretchable applications for electrochromic films. Furthermore, the nonreactive and impermeable nature of graphene increases the durability of the device through increased resistance to external impurities. In addition, the incorporation of ferroelectric materials allows the device to exhibit nonvolatile usage; that is, devices can remain transparent with no external power source. Furthermore, devices may exhibit a charging effect, permitting recovery of energy stored in alignment of ferroelectric dipoles within the ferroelectric material.
