With reference to figure 5, show the one-period of lens board and the corresponding relation of described CF substrate 502, described lens board be arranged on described CF substrate 502 before, described lens board is towards observer's one side, CF substrate 502 be positioned at lens board 512 after.Corresponding Y the sub-pix of cycle a of each described semicylindrical lens 512, be each described cycle a be width in the direction that follows of each sub-pix Y doubly, wherein Y is greater than 2 natural number, in the present embodiment, the value of described Y is 2, be two sub-pixs on the corresponding CF substrate 502 of described semicylindrical lens 512, be specially a left pixel 508a and a right pixel 508b.
With reference to figure 5, Fig. 6 and Fig. 7, the angle between the direction of described elongated semicylindrical lens 512 and the direction of described the first light shielding part Part I 509a is 90 degree.
Can find out in conjunction with formula one and Fig. 4, when the angle of described semicylindrical lens 512 and the first light shielding part Part I 509a is 90 while spending, no matter which kind of the cycle a of the first light shielding part Part I 509a spacing and semicylindrical lens 512 is while being related to, the spacing p value of Moire fringe all levels off to 0, due in the time that the spacing p of Moire fringe is less than 200 μ m, human eye just can not distinguish, so the Moire fringe that described semicylindrical lens 512 and the first light shielding part Part I 509a form can be ignored.
Then with reference to figure 5, Fig. 6 and Fig. 7, the direction of described elongated semicylindrical lens 512 and described the first shading not angle of Part II 509b are 0 degree.
As mentioned above, in the direction parallel with semicylindrical lens 512, spacing between the first light shielding part Part II 509b is b, two sub-pixs on a corresponding CF substrate 502 of semicylindrical lens 512, be that a equals 2b, the first shading is ratio k=b/a=1/2 of the spacing b of Part II 509b and the cycle a of semicylindrical lens 512 not.Can find out from accompanying drawing 4, now the spacing P of Moire fringe is approximately 3 to 4mm, i.e. 3000 μ m to 4000 μ m, and human eye can be felt obvious light and shade inequality in the time observing.
In the present embodiment, because being provided with the second light shielding part 510 in each sub-pix, each the first adjacent light shielding part Part II 509b and the second light shielding part 510 interval each other, be in the parallel direction of semicylindrical lens 512, spacing between adjacent each light shielding part is b/3, the ratio k of light shielding part and grating space '=(b/3)/a=1/6, the k' that the present embodiment provides is prior art 1/3.According to the rule shown in Fig. 4, the 3 d display device that the present embodiment provides, the spacing p of Moire fringe will significantly decline.
Sub-pix is divided into 3 parts by described the second light shielding part 510 in the present embodiment, and in other embodiments, sub-pix can also be divided into by the second light shielding part 510 part of other quantity, and the spacing of adjacent light shielding part is other values.Fig. 8 is the ratio n of the spacing of 512 cycle of lens a and light shielding part while getting different value, the simulation drawing of Moire fringe spacing p.In Fig. 8, the lens cycle is fixed value 135 μ m, the span of the spacing of light shielding part is 9.64-135 μ m, described n value is respectively 1,2,3 ... 14, and the angle of the direction of described lens and described the second light shielding part 510 is 1 degree, because in product actual production, how many times some errors of angle between lens 512 and the second light shielding part 510 light shielding parts, simulate and more approach actual conditions with 1 degree.
As can be seen from Figure 8, in the time that the ratio n of lens cycle a and the second light shielding part 510 spacing is larger, the spacing of Moire fringe is less.If while described the second light shielding part 510 not being set, adjacent light shielding part is the first light shielding part Part II 509b, and n equals 2, and the spacing of Moire fringe exceedes 4000 μ m.And in the present embodiment, sub-pix is divided into 3 deciles by described the second light shielding part 510, n value equals 6, Moire fringe spacing below 2000 μ m, thereby effectively reduced the spacing of Moire fringe, significantly improve the interference problem of Moire fringe.
