It is Wp with 2) width, the viewpoint spacing of adjacent parallax image is people's eye pupil pitch of holes Q, human eye distance 2D display screen in the x direction
Distance be L, left eye in y-direction the distance apart from display screen most bottom side be Y, 20 parameter of grating are as follows: raster pitch (transparent area
The sum of domain and lightproof area width) it is Ws, wherein and transmission region and lightproof area width are respectively Ww and Wb, and display screen 10 is in x
On direction at a distance from slit grating 20 be D, the transmission region of the most bottom side of slit grating 20 in y-direction apart from display screen 10 most
Bottom side is that distance is Y '.
It is similar according to triangle, available following relationship:
In formula,
Ws=Ww+Wb, Ww=Wb (5)
It can be obtained by formula (1)-(5):
The width Ww of the transmission region of slit grating 20 and the width Wb and sub-pixel of lightproof area can be obtained by formula (6)-(9)
Width Wp it is related to interocular distance Q, the width Wp of sub-pixel is determined by display screen 10, the interocular distance of different viewers
Q has fine distinction, it will usually in 65mm or so.It is considered that interpupillary distance is that 65mm is constant, simple eye position is tracked；It can also chase after
The position of track eyes calculates the size of interocular distance Q, then thus extrapolates the width Ww of 20 transmission region of slit grating and hide
