    Abstract: A system may have windows. A window in the system may have first and second window layers such as structural layers of glass. The window may have a light guide layer between the first and second window layers. The light guide layer may have cladding layers and a core layer between the cladding layers. The core and cladding refractive index values may be selected so that the refractive index of the core is greater than the refractive index of the structural layers of glass while the refractive index of the claddings is less than the refractive index of the structural layer of glass. Light-scattering structures may be formed on the light guide to extract some of the light within the light guide and thereby provide illumination for the system.

  • Patent number: 11822165
    Abstract: A display may have display layers that form an array of pixels. An angle-of-view adjustment layer may overlap the display layers. The angle-of-view adjustment layer may include an array of adjustable light blocking structures formed from electrochromic material. The electrochromic material may be interposed between first and second electrode layers. When it is desired to operate the display in a private viewing mode, control circuitry may apply a current to the first and second electrodes that causes the electrochromic material to become more opaque, thereby restricting the angle of view of the display. When it is desired to operate the display in a public viewing mode, control circuitry may apply a current to the first and second electrodes that causes the electrochromic material to become more transparent, thereby opening up the angle of view of the display.
