Electrochromic Patents (Class 359/265)
  • Patent number: 10890820
    Abstract: Window units, for example insulating glass units (IGU's), that have at least two panes, each pane having an electrochromic device thereon, are described. Two optical state devices on each pane of a dual-pane window unit provide window units having four optical states. Window units described allow the end user a greater choice of how much light is transmitted through the electrochromic window. Also, by using two or more window panes, each with its own electrochromic device, registered in a window unit, visual defects in any of the individual devices are negated by virtue of the extremely small likelihood that any of the visual defects will align perfectly and thus be observable to the user.

  • Patent number: 10767143
    Abstract: Several of the films that comprise various energy producing or control devices, for example, electrochromic devices, lithium batteries, and photovoltaic cells, are sensitive to moisture in some way. They may be especially vulnerable to moisture at particular stages during their fabrication. It may also be highly desirable during fabrication to be able to wash particulates from the surface. The particulates may be generated some aspect of the fabrication process, or they may arise from the environment in which the fabrication takes place. This invention shows ways to remove said particles from the surface without incurring the damage associated with typical washing processes, resulting in higher manufacturing yields and better device performance.

  • Patent number: 10712604
    Abstract: The present invention provides a display panel and a method for manufacturing the same. The method comprises steps of forming a black matrix and forming a sealant, wherein the black matrix layer contains a thermochromic material at the position corresponding to the sealant, so that when the sealant is cured with ultraviolet light, the thermochromic material layer is transparent. In such case, a side of the first substrate away from the sealant can be irradiated and ultraviolet light passes through the first substrate and the thermochromic material to cure the sealant, thus achieving a uniform irradiation of ultraviolet light and a high curing efficiency. After the sealant is cured, the thermochromic material can become black by changing the temperature thereof so as to avoid the light leakage.

  • Patent number: 10703179
    Abstract: Discussed is a lighting apparatus having an organic light-emitting element configured as a transparent window and provided with an optical filter to prevent transmission of light when light having an intensity higher than a preset intensity is incident on the lighting apparatus so as to allow the lighting apparatus to be driven in a transparent mode, an opaque mode, and a lighting mode. The organic light-emitting element includes first and second electrodes and an organic emission layer disposed between the first electrode and the second electrode to emit light when a signal is applied thereto. The organic light-emitting element performs single-side emission or dual-side emission. The optical filter is formed of a photochromic material or an electrochromic material to make the lighting apparatus be opaque so as to adjust the transmissivity of light when the light having the intensity higher than the preset intensity is incident on the lighting apparatus.
