  • Light-guiding device, light-guiding method and display apparatus for guiding light transmission
    Patent number: 9958689
    Abstract: A light-guiding device includes a first transparent substrate having an incident surface and a transmission surface; a first parallax barrier located on the first transparent substrate and configured to allow a first type of light in the light source to be converged to a first assemblage point and allow a second type of light in the light source to be converged to a second assemblage point, wherein the first parallax barrier includes a plurality of light-shielding units, each of which is produced by using a micro-electro-mechanical system switch, and includes a light-shielding body; an attraction cantilever, connected with the light-shielding body, an attraction and a separation of the attraction cantilever configured to force the light-shielding body to move so as to change transmission of the light in the light source.
