Abstract
The present invention relates to a multi-view three-dimensional (3D) display apparatus including a display panel in which pixels (or subpixels) outputting an image are arranged and a parallax barrier disposed on a front surface of the display panel and including a plurality of apertures, wherein the apertures of the parallax barrier are set according to a Fresnel number.
Claims7
A multi-view 3D display apparatus comprising:
- a display panel in which pixels (or subpixels) outputting an image are arranged;
- and
- a parallax barrier disposed on a front surface of the display panel and including a plurality of apertures,
- wherein the apertures of the parallax barrier are set according to a Fresnel number calculated by the following expression,
- nFR≅¼1/λLβ2(Wp·Dvp) [Expression]
- where, nFR denotes a Fresnel number, λ denotes a central wavelength of visible light, L denotes an optimum viewing distance, β denotes a PB aperture ratio, WP denotes a horizontal width of a pixel in which a view image is arranged, and DVP denotes a distance between designed viewpoints.
