  • Patent number: 11852941
    Abstract: A cholesteric liquid crystal display device includes a solar cell, a first substrate, a shielding layer, a first electrode layer, a cholesteric liquid crystal layer, a second electrode layer and a second substrate stacked sequentially from bottom to top. The solar cell includes a metal wiring pattern layer. The shielding layer corresponds to the upper side of the metal wiring pattern layer, and is used to reduce the reflection of light from the metal circuit pattern layer. In this way, the cholesteric liquid crystal display device replaces the traditional black absorbing layer with the black material of the solar cell, which can not only absorb light, but also display the image with self-sustaining power. The cholesteric liquid crystal display device shields the arrangement of the metal wiring pattern layer through the shielding layer, which can ensure the image quality of the display panel.

  • Publication number: 20220221657
    Abstract: An optical fiber end securing structure and a method of securing an optical fiber end are introduced. The optical fiber end securing structure includes a stub component, a substrate and an adhesive component. The stub component is cylindrical. The stub component has axially a through hole for receiving an optical fiber. The substrate has a securing groove. Two walls of the securing groove extend in the axial direction of the stub component. The distance between the two walls is less than the diameter of the stub component in the radial direction. The outer circumferential surface of the stub component is in linear contact with apexes of the two walls. The adhesive component fills the securing groove and connects the securing groove and the stub component. Therefore, the optical fiber end securing structure and the method of securing an optical fiber end enable the optical fiber to undergo high-precision engagement.

  • Publication number: 20220208618
    Abstract: The present invention discloses an optical detection apparatus for defining a detection surface on a carrier unit for a wafer in a semiconductor manufacturing process so as to obtain a corresponding detection image, wherein a vertical movement path for another device to move is defined above the carrier unit. The optical detection apparatus includes a support, and an imaging device disposed on the support and configured to be non-interfering with the movement path. The imaging device includes a lens group, an image capturing portion and a moving base. With the moving base, the photosensitive element of the image capturing portion is allowed to move horizontally relative to the lens group, and the imaging position can be adjusted, preventing image deformation or a reduced resolution easily caused by capturing at an oblique angle. Thus, the optical detection apparatus resolves complications of additionally mounting an optical detection apparatus in an optical detection environment within a narrow space.

  • Publication number: 20220113479
    Abstract: A terminal portion structure of an optical transmission element includes a light guiding component, glass protection layer and convex lens. The light guiding component includes a core and a cladding enclosing the core. The cladding is of a lower refractive index than the core, allowing light signals to be transmitted in the light guiding component by total internal reflection. The glass protection layer covers at least a terminal portion of the light guiding component. The convex lens is disposed on one side of the glass protection layer. The cross section of the terminal portion of the light guiding component tilts relative to the axial direction of the light guiding component. The optical axis of the convex lens is perpendicular to the axial direction of the light guiding component. The focal point of the convex lens is located at the cross section of the terminal portion of the core.
