<p>A three-dimensional imaging system (700) comprising a display device (701) and shutter glasses (702). A lens (200) of the shutter glasses (702) comprises a quarter wave plate (201), a first polarizer (202), a first electrically conductive glass (203), a liquid crystal layer (204), a second electrically conductive glass (205), and a second polarizer (206). An incident light introduced to the quarter wave plate (201) is a circularly polarized light; the circularly polarized light introduced is transformed by the quarter wave plate (201) into a linearly polarized light. The polarity of the first polarizer (202) and the quarter wave plate (201) form a 45 degree angle therebetween, allowing the linearly polarized light to be constantly parallel to the polarity of the first polarizer (202). Thus, light passes through normally when the shutter glasses are moved by a user. As the shutter glasses have no polarization angle problems, diffraction, ghosting, and black screen or partial black screen are prevented.</p> |
