Wide-viewing-angle integral imaging 3D display apparatus
2015
The invention discloses a wide-viewing-angle integral imaging 3D display apparatus. Horizontal pitches of pin holes in any row of a pinhole array with gradually-varied aperture are the same, the horizontal aperture width of the pinholes in the pinhole array with the gradually-varied aperture is gradually increased from the middle to the two sides, and the horizontal width of a reconstruction 3D vision area of an image primitive in a micro-image array is gradually increased from the middle to the two sides via the pinholes in the pinhole array with the gradually-varied aperture so that the horizontal width of a public area of all the image primitive reconstruction 3D vision areas is increased, and the integral imaging 3D display visual angle is wider than the display visual angle of a non-crosstalk integral imaging 3D display apparatus based on polarization grating in the prior art.
