Case 26 is collectively constituted, and please continue to refer to Fig. 4 A, unit geometrical pattern 26 is rectangle, consequently, it is possible to which a plurality of geometrical patterns 26 are just
An optical cement pattern can be used as in visible area one lattice-shaped pattern 30 of formation.It is worth noting that：The bar being made up of frame glue
The non-overlapping copies each other of shape pattern 28, to avoid glue material at storehouse blocked up, in addition, frame glue is the material of high-penetration rate.
Fig. 4 B are the optical cement pattern according to depicted in another preferred embodiment of the present invention, wherein with identical function
Component is with same components symbology.As shown in Figure 4 B, similarly, unit geometrical pattern 26 is the strip pattern being made up of frame glue
Formed combined by 28, the non-overlapping copies each other of strip pattern 28, and Fig. 4 A difference are：Unit geometry in the present embodiment
Pattern 26 is hexagon, in addition, the optical cement pattern that the geometrical pattern 26 of a plurality of repetitions is constituted is a honeycomb-like pattern 40.
Fig. 4 C are the optical cement pattern according to depicted in another preferred embodiment of the present invention.As shown in Figure 4 C, similarly,
Unit geometrical pattern 26 is to be formed combined by the strip pattern 28 being made up of frame glue, the non-overlapping copies each other of strip pattern 28, and
Unit geometrical pattern 26 is rectangle, and Fig. 4 A difference is：In the present embodiment, the structure of geometrical pattern 26 of a plurality of repetitions
Into optical cement pattern be an interlaced pattern 50, and other two rectangles that a rectangle in interlaced pattern 50 can be adjacent thereto
A shared length of side, and another rectangle that the rectangle in Fig. 4 A in lattice-shaped pattern 30 can be adjacent thereto shares a length of side.
Above-mentioned three kinds of optical cement patterns all suitable for the present invention panel applying method, hereafter will using Fig. 4 A optical cement pattern as
Example, but Fig. 4 B and Fig. 4 C optical cement pattern, can all be handled in an identical manner.
Referring once again to Fig. 4 A, after lattice-shaped pattern 30 is formed, then, a curing process is carried out, such as with heat cure
The curing process that the material property of processing, ultraviolet light curing process or other correspondence frame glues is adapted to carrys out primary solidification clathrate figure
Case 30 so that solidification lattice-shaped pattern 30 has tentatively firm shape, will not be flowed to surrounding.
As shown in figure 5, a face glue coating process is carried out, and in dispensing mode in each geometrical pattern 26, with an optical cement,
For example a face glue one face glue pattern 32 of formation is on substrate 22.The viscosity of frame glue is more than the viscosity of face glue, in addition, the present invention is made
Frame glue and face glue are all the materials of high-penetration rate, and frame glue and face glue have close penetrance and refractive index, preferably
Ground, frame glue and face glue have substantially identical penetrance and refractive index.
As shown in Figure 6 there is provided a cover plate 34, cover plate 34 can be plastics strengthened glass or other materials, and
One side on cover plate 34 can be optionally provided with touch control component (not shown), then cover cover plate 34 on substrate 22,
As shown in fig. 7, cover plate 34 and substrate 22 are pressed so that face glue pattern 32 is evenly distributed in each geometrical pattern by pressing
Turn into face glue pattern 132 in 26, then, carry out one side adhesive curing processing procedure, to solidify face glue pattern 132, face adhesive curing processing procedure can
The curing process that is adapted to the material property using heat cure processing, ultraviolet light curing process or other corresponding surface glue solidifies
Face glue.After face adhesive curing processing procedure, cover plate 34 and substrate 20 have been fitted, and form a panel construction 36, so far the face of the present invention
The applying method of plate was completed already.Although in Fig. 7, face glue pattern 132 is to be indicated with oblique line, and geometrical pattern 26 is with lines mark
Show, this purpose is for easily distinguishable face glue pattern 132 and geometrical pattern 26 in the example shown, yet with frame glue of the present invention and face
Glue has close or identical penetrance and a refractive index, therefore with the naked eye and cannot be distinguished from face glue shape actually in visible area 22
Into face glue pattern 132 and and frame glue formation both position of geometrical pattern 26, it is possible to avoid causing panel construction
The problem of depending on imitating bad.If distinguishing the face glue pattern 132 and the geometric graph of frame glue formation of the face glue formation in panel construction
The position of case 26, using Raman spectrometer or the ultraviolet light panel construction 36 of excess so that frame glue and face glue yellow
Change with mist degree, and then distinguish the position of face glue pattern 132 and geometrical pattern 26.
On the premise of frame glue and face glue penetrance and refractive index all same, to reach preferable visual effect, frame glue and
Both penetrances of face glue are can be controlled between 90% to 100% scope, and both refractive indexes of frame glue and face glue can control
Between 1.4 to 1.6 scope.According to the preferred embodiments of the invention, the penetrance of frame glue and face glue is 99.9%, frame glue
When refractive index with face glue is 1.49, its visual effect is optimal.
Because frame glue is formed at visible area by the present invention with special repeated-geometric patterns, visible area is thus utilized into geometry
Pattern is divided into more several zonules, and face glue is inserted into zonule in dispensing mode in zonule afterwards, due in laminating
In processing procedure, the diffusion path of face glue is shorter, therefore can be evenly distributed in zonule, can lift overall uniformity, also because
The method of this present invention is particularly suitable for use in large-sized panel of fitting.Furthermore, because taking the side of the coated face glue in zonule
Face glue demand in formula, each zonule is easy to control, it is possible to decrease the possibility of starved.In addition, the geometrical pattern of the present invention is set
Meter is simple, can reduce the time of design.In addition, the present invention is specially penetrated using with identical refractive index and with identical
The face glue and frame glue of rate, therefore frame glue can be coated in visible area, with reduce regard imitate it is bad with low light source utilization rate the problem of.
The preferred embodiments of the present invention are these are only, are not intended to limit the scope of the invention, it is every to utilize this hair
Equivalent structure or equivalent flow conversion that bright specification and accompanying drawing content are made, or directly or indirectly it is used in other related skills
Art field, is included within the scope of the present invention.
