412 or 413) association set；Backsight sub-pattern has setting, the backsight sub-pattern phase of both sides in the both sides of same prism 301
Together；The light that backsight sub-pattern is thrown towards the first relative prism facets 302 or the second prism facets 303, will after a wherein prism facets
Total reflection or reflection occur in another prism facets, by base material after total reflection or reflection, reaches transmissive portions 101 and projects.By
This obtains the stereoscopic vision of the 4th view directions.
The backsight sub-pattern relative with the first prism facets 302, the light transmitted to the first prism facets 302 will reach the second prism
Face 303, it is totally reflected in the second prism facets 303；Similarly, the backsight sub-pattern relative with the second prism facets 303, to the second rib
The light that minute surface 303 transmits will reach the first prism facets 302, be totally reflected in the first prism facets 302；As shown in figure 8, the former is complete
The light of reflection or reflection invests left side, the corresponding visual angle for left back；As shown in figure 9, the light of the latter's total reflection or reflection is thrown
To the right, the corresponding visual angle for right back.The visual angle at left and right sides rear collectively forms the 4th view directions.
As shown in figure 3, the second raster pattern pattern layer 42 shows three groups of backsight candy strips, same corresponding side back sight direction
, different depth, the stereo-picture of the different depth of field.
In some alternative embodiments of the present embodiment, as shown in figure 4, on the relative second surface 202 of barrier portion 102
Prism 301 is again provided with, now, two waists of this prism 301 are provided with backsight sub-pattern, and backsight sub-pattern sets this rib
On two waists of mirror 301, it is arranged on relative to favouring on second surface 202, backsight being inclined on second surface 202
Pattern, the light projected towards the first prism facets 302 or the second prism facets 303 be also it is inclined, the light for being now totally reflected or reflecting
Angle of reflection is smaller, and the 4th view directions will be tilted more, and in observation, the sensation given people will more rearward, more truly.
In the present embodiment, grating display panel includes the stereoscopic vision in four different visual angles directions, multiple due to obtaining
The stereoscopic vision of view directions, after this grating display panel, people can observe left back successively when being observed by left and right
Side, front left side, face, forward right side, the stereoscopic vision of right lateral side, whole process gives beautiful visual experience, is more nearly
Real observation experience, thus increase the third dimension of grating display panel.
The protective layer 50 of the grating display panel is used for protective film, and backlight layer 60 can increase brightness, there is provided illumination.
It would be recognized by those skilled in the art that it is possible that numerous accommodations are made to above description, so embodiment and attached
Figure is intended merely to describe one or more particular implementations.
It is counted as example embodiment of the present utility model although having been described above and describing, those skilled in the art will be bright
In vain, it can be variously modified and replaced, without departing from spirit of the present utility model.Repaiied furthermore it is possible to make many
Change so that particular case is fitted into religious doctrine of the present utility model, without departing from the utility model central concept described here.
