Step S401 in described N viewpoint view, along the first direction of described the first black line, shows successively the display cycle of H preset length in every a line rectangular pixels;
Step S402 shows b N viewpoint sequence units in each display cycle, and b is positive integer;
Step S403, inserts and shows compensation pixel between the described N viewpoint sequence units in each display cycle, so that described b bar grating can align, covers a display cycle.
B the N viewpoint sequence units comprising for H display cycle in every row of N viewpoint view and H display cycle and the concrete arrangement mode of compensation pixel, please refer to Fig. 5, Fig. 5 is the arrangement mode schematic diagram of every row of N viewpoint view in the embodiment of the present application two; As shown in the figure, row of N viewpoint view 501 comprises H display cycle 502, in the described H display cycle 502 in each display cycle rectangular pixels arrange order and displaying contents all identical, and first rectangular pixels of h display cycle is adjacent with last rectangular pixels of h-1 display cycle; Last rectangular pixels of h display cycle is adjacent with first rectangular pixels of h+1 display cycle, and wherein h is positive integer, and 1<h<H.Each display cycle 502 comprises at least one N viewpoint sequence units 503 and at least one compensation pixel 504, wherein, in each N viewpoint sequence units 503, along first direction, from the 1st rectangular pixels to N rectangular pixels, the parallax between each matrix pixel and described the 1st rectangular pixels forms increasing sequence; In a display cycle 502, compensation pixel 504 i.e. X in figure, inserts and is presented between described N viewpoint sequence units 503.
For how making described b bar grating align, cover a display cycle, set-up mode is as follows in detail:
The raster pitch P=(N*P of grating in grating type stereoscopic display device was described in embodiment mono-
sub+ Δ P) * cos θ, wherein, Δ P is described dislocation value, P
subfor the width of each rectangular pixels along the direction of described the first black line.
While having b N viewpoint sequence units and a compensation pixel in a display cycle, the length of each display cycle along the direction of the first black line is (b*N+a) * P
sub; And the length of the line segment of first black line of each grating covering is N*P
sub+ Δ P, when each display cycle equals each grating and covers b times of length of line segment of first black line along the length of the direction of the first black line, b bar grating can align covering a display cycle, i.e. (b*N+a) * P
sub=b* (N*P
sub+ Δ P), time, b bar grating can align and cover a display cycle.
To sum up, to formula (b*N+a) * P
sub=b* (N*P
sub+ Δ P) carry out after abbreviation, show that the ratio as a and b equals Δ P and P
subratio time, b bar grating can align and cover a display cycle.
For example, the P that is 1/3rd as Δ P
subtime, each display cycle comprises 3 N viewpoint sequence units and 1 compensation pixel.
To sum up, the ratio as a and b equals Δ P and P
subratio time, b grating just equals a display cycle along the width of the direction of the first black line along the width of the direction of the first black line.Be that b grating can just align with a display cycle, to realize the accurate light splitting of grating pair rectangular pixels in the display cycle.
For example,, when Δ P equals
p
sub, depending on points N, equaling at 3 o'clock, the width of each display cycle along the direction of the first black line is (4*3+1) * P
sub, i.e. 13*P
sub;
Now, grating along the width of the direction of the first black line is
?
That is to say, 3 gratings can just align with a display cycle.
