20130128351PRISM ARRAY TO MITIGATE MOIRE EFFECT IN AUTOSTEREOSCOPIC DISPLAYS - An autostereoscopic display device includes a pixelated image source and an optical element. The pixelated image source is located along a pixel plane and includes a set of pixels and dark regions substantially filling a remainder of the pixelated image source. The pixels are arranged in a pixel array having a pixel duty factor that is defined as pixel size over pixel pitch along the pixel plane and has a value of 1/N. The optical element is located between the pixel plane and an observer plane and is configured to form a projection array of pixel projections on the observer plane. The projection array has a projection duty factor defined as pixel projection size over pixel projection pitch along the observer plane. The projection duty factor is substantially equal to 1 such that two adjacent ones of the pixel projections bound one another on the observer plane.05-23-2013
20130155502AUTOSTEREOSCOPIC 3-DIMENSIONAL (3D) DISPLAY APPARATUS AND DISPLAY METHOD THEREOF - There are provided an autostereoscopic 3-Dimensional (3D) display apparatus and a display method thereof. In the autostereoscopic 3D display apparatus, a 3D display is disposed in a standing position, and a reflection structure reflects light emitted from the screen of the 3D display to provide a 3D image in a 3D space.
