Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
Embodiment one
The prismatic lens assembly of first embodiment of the present invention, comprises at least two-layer prismatic lens, and every layer of prismatic lens and the face that adjacent ribs eyeglass is adjacent are with it bonding plane, and described bonding plane comprises adhesion zone; Be filled in the sticky object between described adhesion zone.
The prismatic lens assembly of the present embodiment, at least two-layer prismatic lens, every layer of prismatic lens and the face that adjacent ribs eyeglass is adjacent are with it bonding plane, and described bonding plane comprises adhesion zone; Be filled in the sticky object between described adhesion zone.The adhesion zone of such setting and sticky object, increase bond area, what make between prismatic lens adjacent in prismatic lens assembly is bonding more firm, reduces the probability that prismatic lens is peeling, and then makes the serviceable life of the backlight comprising above-mentioned prismatic lens assembly elongated.
The concrete structure of prismatic lens assembly can be the structure as shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 5, and the face that every layer of prismatic lens 100 is relative with adjacent ribs eyeglass 100 is with it bonding plane, and described bonding plane comprises adhesion zone; The adhesion zone of the relative bonding plane of adjacent two-layer described prismatic lens is mutually bonding adhesion zone; Described sticky object 200 is filled between described mutually bonding adhesion zone.The adhesion zone of such setting and sticky object, increase bond area, and what make between prismatic lens adjacent in prismatic lens assembly is bonding more firm, reduces the probability that prismatic lens is peeling; Wherein, namely the face that every layer of prismatic lens 100 is relative with adjacent ribs eyeglass 100 is with it every layer of prismatic lens and adjacent ribs eyeglass is adjacent with it face.
Concrete, in the structure of the such as assembly of prismatic lens shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 5, described mutually bonding adhesion zone is oppositely arranged.The relatively bonding adhesion zone be oppositely arranged, bond area is at least the projected area of adhesion zone on prismatic lens, further increases bond area.Wherein, described mutually bonding adhesion zone is defined as the described adhesion zone of adjacent described bonding plane.
In order to trying one's best under the prerequisite of little impact through the light of prismatic lens assembly, increase bond area, as shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 5, described bonding plane also comprises the region being positioned at centre, is positioned at middle region around described in described adhesion zone is looped around.
Like this, adhesion zone is the shaped as frame adhesion zone for being positioned at bonding plane edge, and do not affect the printing opacity of prismatic lens first mesozone, the brightness of prismatic lens assembly is higher.
As the preferred mode of one, as shown in Figures 2 and 3, described sticky object 200 is viscoses of shading sticky object, such as black.The shading sticky objects such as the viscose of black, as sticky object, while playing bonding effect, can also prevent light from dispersing from the edge of prismatic lens assembly to surrounding.Like this, the problem comprising the backlight source module marginal existence bright line of such prismatic lens assembly improves.
