  • Patent number: 10139719
    Abstract: This aerial image display device is provided with an optical plate having a plurality of reflective surfaces orthogonal to each other in plan view, a projection device, a specular mirror, and a screen. The mirror includes a counter mirror disposed spaced apart from the optical plate at the opposite side of a focused image M across the optical plate. The projection device and the screen sandwich a light path between the counter mirror and the optical plate at the opposite side of the focused image (M) across the optical plate. The projection light emitted from the projection device is incident on the screen after reflecting from the counter mirror, and then incident on the optical plate after reflecting from the screen and then from the same counter mirror.

  • Patent number: 9377676
    Abstract: An autostereoscopic display device includes a projector, an angle-enlarging module, a screen, and a polarization selector. The projector provides a lamp image unit with a first polarization state. The angle-enlarging module includes a deflecting plate, a wavelength retarder, and a polarizer. The deflecting plate has a first deflecting segment and a second deflecting segment alternately with each other. The first and the second deflecting segments respectively deflect the lamp image unit to a first direction and a second direction different from each other. The wavelength retarder has a transmitting segment aligned to the first deflecting segment and a wavelength retarding segment aligned to the second deflecting segment. The transmitting segment maintains the first polarization state when the lamp image unit passes therethrough. The wavelength retarding segment converts the first polarization state into a second polarization state.

  • Patent number: 9151959
    Abstract: An optical system that projects a real image to a location in free space and includes one or more features located along the optical path that enhance the viewability of the real image. The optical system includes a converging element for converging a portion of source light so as to form the real image. One viewability-enhancing features is the use of a broadband reflector-polarizer having high transmitting and reflecting efficiencies. Another viewability-enhancing features is the use of polarizing elements having substantially matched bandwidth responses and/or comprising an achromatic design. An additional viewability-enhancing feature is the use of a wide-view film to increase the viewing angle of the image.
