Include endpoint value.Eyes and the 3 d display of user according to above-mentioned two equation, under known product structure, can be calculated
Optimum sight between 11 is apart from b.
With reference to Figure 17, Figure 17 is that a kind of principle of three-dimensional display apparatus visual angle provided in an embodiment of the present invention moving range is shown
It is intended to.For single eyes when position a ' moves into place b ', between the eyes and 3 d display of user away from
From for b, display floater and the distance between adjustable light barrier a, sub-pixel length in a first direction is c, hollow out grizzly bar width
Spend for s, shading grill width is m, now displacement shift of single eyes ' relation with grating displacement shift
For:
Wherein, general a=0.5mm.Generally 50 μm of grating displacement shift.The span of b is 500mm-
2500mm, displacement shift of single eyes ' span be 50mm-1250mm.According to the displacement of eyes, adjust
Save grating displacement so that user eyes midpoint and adjustable light barrier meet geometry site when three dimensional display,
So, when human eye carries out continuous moving, optimal viewing location can be in all the time come human eye by the movement of grating, lifting
Human eye watches the seriality that 3d shows, thus improving the effect of three dimensional display.
