First Claim
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, each pixel comprising multiple sub-pixels; and
a grating device coupled to the display panel and having a plurality of grating elements based on liquid crystal to guide lights associated with the plurality of display pixels into predetermined viewing directions, the grating device being one of a lenticular lens grating and a slit grating,wherein;
the plurality of grating elements are arranged in parallel;
the plurality of grating elements cover the plurality of display pixels and are tilted at an inclination angle with respect to the display pixels, and each grating element comprises a plurality of electrodes arranged at the inclination angle to cause the liquid crystal to form the grating element when being applied with various driving voltages; and
a width of the electrodes is less than or equal to a width of a sub-pixel, and a width between any two electrodes is less than or equal to the width of a sub-pixel.
