Abstract
A dual-directional 3D image displaying method, being used in a case when a flat-panel display screen and a view separation device are used for dual-directional 3D image displaying, which comprises the steps of: using a display screen having a sub-pixel arrangement of 45-degree slant angle to display a multi-view 3D combined image; and using a view separation device featured by a 45-degree slant angle to perform a view separation operation upon the multi-view 3D combined image. Thereby, an object of dual-directional displaying of 3D images can be achieved using only one view separation device, without being bothered by conventional problems, such as cross-talk and color distortion.

A dual-directional 3D image displaying method, being used in a case when a flat-panel display screen and a view separation device are used for dual-directional 3D image displaying, comprising the steps of:
- using a display screen having a sub-pixel arrangement of 45-degree slant angle to display a multi-view 3D combined image;
- and
- using a view separation device featured by a 45-degree slant angle to perform a view separation operation upon the multi-view 3D combined image,
- wherein the multi-view 3D combined image of 45-degree slant angle is established using the following formulas:

- the display screen is composed of N×M sub-pixels, in which N represents the total number of sub-pixels in a horizontal direction of the display screen, and M represents the total number of sub-pixels in a vertical direction of the display screen;
- in addition, the horizontal position and the vertical position of any single sub-pixel in N×M display screen are represented respectively using the index i and j, whereas 0≦j≦N−1 and 0≦i≦M−1;
- and moreover, VΛ(i, j) represents the sub-pixel data of a single-view image VΛ at position (i, j) of the display screen;
- A represents a view number, and 0≦Λ<n, while n is the total amount of view;
- m is a positive integer representing a number of sub-pixels of a smallest view display unit in horizontal direction, while Q is a positive integer representing a number of sub-pixels of a smallest view display unit in vertical direction;
- A is an integer representing a horizontal displacement phase;
- Π is an integer representing a horizontal displacement amplitude;
- and int is a round down integer function, and Mod is a function of taking a remainder;
- n, m, Q, Δ and Π are determined according to a set of optimization parameters wherein:
- for a display screen with square-shaped configuration, the set of optimization parameters is:
- n≧2, m≧1, Q≧1, Δ=0, Π=1;
- for a display screen with triangle-shaped configuration, the set of optimization parameters is:
- n≧2, m equal to multiplies of 2, Q≧1, Δ=1, Π=2;
- for a display screen with left-slanting square-shape configuration and a display screen with perpendicular square-shape configuration, the set of optimization parameters is:
- n≧2, m≧1, Q=2, Δ=0, Π=1.
