Should be appreciated that the data of so use can be exchanged in the appropriate case, in order to embodiment of the present utility model described herein. In addition, term " includes " and " having " and their any deformation, it is intended to cover non-exclusive comprising, such as, contain series of steps or the process of unit, method, system, product or equipment be not necessarily limited to those steps or the unit clearly listed, but can include clearly not listing or for intrinsic other step of these processes, method, product or equipment or unit.
As what background technology was introduced, the prism top of peep-proof membrane structure of the prior art is linear, often come into question, this utility model is studied for the problems referred to above, propose a kind of peep-proof film, if Fig. 2 is to shown in 6, including substrate layer 10 and be arranged at the transmission layer 20 on substrate layer 10 surface, transmission layer 20 includes multiple transmission units being arranged in order in the first direction and extend in a second direction, first direction and second direction are each parallel to the surface of substrate layer 10, the extended surface of two sidewalls being parallel to second direction of transmission units intersects, and the intersection being crossed to form is positioned at the side away from substrate layer 10 of transmission layer 20, transmission units is on-plane surface away from the surface of substrate layer 10.
Owing to transmission units has the sloped sidewall that two extended surfaces intersect in above-mentioned peep-proof film, intersection is positioned at the side away from substrate layer 10 of transmission layer 20, and transmission units is on-plane surface away from the surface of substrate layer 10 side, so that product surface is not easily formed rectilinear wire drawing lines, significantly reduce drawing pattern degree, and then when above-mentioned peep-proof film being arranged in pairs or groups display, it is possible to reduce and produce mole probability interfered, be effectively guaranteed the outward appearance of peep-proof film and the definition of screen.
In the above-mentioned peep-proof film of this utility model, peep-proof film can also include absorbed layer 30, and absorbed layer 30 includes multiple absorptive unit, and absorptive unit is arranged between adjacent transmissive unit. Wherein, transmission units comprises refractive index is N1Material, it is N that absorptive unit comprises refractive index2And it is not more than N1Material. The critical angle �� c of peep-proof film meets �� c=arcsin (N2/N1), namely the angle less than �� c incides the light on peep-proof film surface and can be absorbed by the absorption layer.
Transmission layer 20 can form the surface away from substrate layer 10 side of peep-proof film with absorbed layer 30. Preferably, one group of adjacent transmission units and absorptive unit at the minimum widith gone up in the first direction more than 70 ��m.

Top is rendered as by this utility model shakes shape up and down, and top becomes discontinuous line segment from linear, destroys the periodicity at top, thus reducing the pixel with liquid crystal panel mole probability interfered occurs.
It is further preferable that the depressed part of wavy surface is identical with the shape of lobe. There is the peep-proof film of above-mentioned preferred structure when arranging in pairs or groups display, it is possible to reduce further and produce mole probability interfered, thus more effectively improve the outward appearance of peep-proof film and the definition of screen. And, it is preferable that H1With H2Difference less than 20 ��m. Limit H1With H2Difference in above-mentioned preferred scope, it is possible to further ensure there is the discontinuous lines that the product surface of peep-proof film can be formed, thus more effectively reducing drawing pattern degree.
When peep-proof film includes spaced transmission units and absorptive unit successively, in a preferred embodiment, on-plane surface includes at least two planar section, and each planar section is parallel with the surface of substrate layer 10, and vertical dimension between each planar section and substrate layer 10 differing, as shown in Figure 4. The on-plane surface of said structure can make at least side of transmission units fill thicker absorptive unit, thus being effectively reduced the drawing pattern degree of shaped article, and then when above-mentioned peep-proof film is arranged in pairs or groups display, significantly reduces and produces mole probability interfered; And, additionally it is possible to ensureing that peep-proof film has on the basis of peep-proof effect, efficiently reduce the total reflection at least interface, side, thus improve the transmitance of peep-proof film.
It is further preferable that on-plane surface includes the vertical dimension vertical dimension more than the first planar section and the 3rd planar section and substrate layer 10 of the first planar section, the second planar section and the 3rd planar section that are sequentially connected in the first direction, the second planar section and substrate layer 10. Namely above-mentioned on-plane surface is the surface with boss, the surface of boss type can not only make the both sides of the cambered surface of transmission units fill thicker absorptive unit, thus more effectively reducing the drawing pattern degree of shaped article, can also ensure that peep-proof film has on the basis of peep-proof effect, efficiently reduce the total reflection at interface, both sides, thus improve the transmitance of peep-proof film.
When peep-proof film includes spaced transmission units and absorptive unit successively, in another preferred embodiment, on-plane surface is that cambered surface extends in a second direction, as illustrated in Figures 5 and 6 to the cambered surface raised away from substrate layer 10 direction. Namely on-plane surface is the cambered surface of a bending, adopt above-mentioned cambered surface as the surface of transmission units in peep-proof film, the absorptive unit that the cambered surface both sides of transmission units are filled can be made thicker, thus significantly reducing the drawing pattern degree of shaped article, and then when above-mentioned peep-proof film being arranged in pairs or groups display, significantly reducing and producing mole probability interfered.
For the peep-proof film that surface is cambered surface of transmission units, it is further preferable that the radius of curvature of cambered surface is 1��30 ��m. Cambered surface adopts has above-mentioned preferred range of curvature radius, the absorptive unit of suitable thickness is filled in the cambered surface both sides that can make transmission units, thus not only significantly reducing on the basis of drawing pattern degree of shaped article, also make the absorptive unit that peep-proof film will not be filled due to cambered surface both sides blocked up and cause that the transmitance of peep-proof film reduces.
In the above-mentioned peep-proof film of this utility model, it is preferable that two sidewalls with the angle being perpendicular between substrate layer 10 and the arbitrary section parallel with second direction more than 6 �� and less than or equal to 15 ��. The transmission units with above-mentioned preferred angular range ensure that peep-proof structure is prone to processing and is easy to molding making, and peep-proof film also has higher transmitance and peep-proof angle simultaneously.
At least two planar section is included for above-mentioned on-plane surface and above-mentioned on-plane surface is the peep-proof film to the cambered surface raised away from substrate layer 10 direction, when transmission layer 20 and absorbed layer 30 formed peep-proof film away from the surface of substrate layer 10 side time, preferably, transmission layer 20 forms parallel with substrate layer 10 and away from substrate layer 10 surface with absorbed layer 30.
