  • 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.
