Abstract:
1. A three-dimensional (3D) display apparatus for displaying a 3D image, comprising: a display panel having a plurality of display pixels arranged in a two-dimensional array, wherein the plurality of display pixels include a first set of display pixels displaying a first view point image of the 3D image and a second set of display pixels displaying a second view point image of the 3D image; and a grating device coupled to the display panel and having a plurality of grating elements to guide lights associated with the plurality of display pixels into predetermined viewing directions, wherein: the grating device is one of a lenticular lens grating and a slit grating; the plurality of grating elements cover the plurality of display pixels and are tilted by rotating a ridge line direction of the plurality of grating elements with respect to a diagonal direction of the plurality display pixels by a non-zero angle from a direction parallel to the diagonal direction such that a tilted direction of the plurality of grating elements forms the non-zero angle with respect to the diagonal direction of the plurality display pixels to reduce Moire patterns based on irregularity caused by the rotated ridge line direction; a controller of the 3D display apparatus re-calculates a display value of a display pixel from the first set of display pixels based on an original value of the display pixel and an original value of a neighboring display pixel from the second set of display pixels, wherein, provided that x and y are integers, the controller of the 3D display apparatus associates a decimal number x.y with a display pixel for re-calculating the value of the display pixel and re-calculates the display value of the display pixel according to the decimal number x.y, wherein x indicates which number of view point image of the 3D image the display pixel is from and y indicates a percentage of the display value of a neighboring display pixel from a different view point image to be included in the display value of the display pixel.
