Multiple embodiments of the present invention will be disclosed with accompanying drawing below, as clearly stated, in many practices
Details will be explained in the following description.It should be appreciated, however, that the details in these practices is not applied
To limit the present invention.That is, the details right and wrong in some embodiments of the present invention, in these practices
It is necessary.Additionally, for the sake of to simplify accompanying drawing, some known usual structures in the accompanying drawings will be with letter with component
What list was illustrated illustrates.
Fig. 1 is the profile of the contactor control device 100 according to one embodiment of the present invention.Contactor control device 100
Comprising first assembly 110, the first adhesion coating 120, the second adhesion coating 130 and the second component 140.First group
Part 110 includes protective layer 112, and protective layer 112 has non-smooth surface S1.First adhesion coating 120 is covered
The non-smooth surface S1 of protective layer 112.Second adhesion coating 130 is located at the first tack coat 120 with protective layer 112
Different both sides, the wherein refractive index difference of the adhesion coating 130 of protective layer 112 and first less than protective layer 112 with
The difference of the refractive index of the second adhesion coating 130.Second component 140 has non-smooth surface S2, the second adhesion
Layer 130 is attached at the non-smooth surface S2 of the second component 140 entirely.
In this, the surface undulation of the surface undulation difference in height of non-smooth surface S2 compared to non-smooth surface S1
Difference in height is bigger.Such as non-smooth surface S2 is often as arranging shielding layer or frame and being formed, non-flat
Whole surface S1 forms out-of-flatness surface for the impact of the processing procedure precision of protective layer 112.The table of non-smooth surface S2
About between 50 microns to 750 microns, the surface undulation of non-smooth surface S1 is highly for face relief height difference

Above step (Fig. 3 A to Fig. 3 C) is described on transparency carrier 114 the multiple steps for carrying out.In order to carry out
First assembly 110 is fitted with the second component, in addition to above-mentioned steps, is also carried out on the second component following
Preparation process.
Reference picture 3D, coating liquid optical cement 130 ' is on the second component 140.As it was previously stated, the second component
The housing 144 with edge shield structure 144a is provided with around 140 panel assembly 142, and has non-smooth
Surface S2.Housing 144 can be formed by metal, such as aluminum or titanium, or housing 144 can by rubber or its
Its plastic material is formed.In order that user can observe display floater, housing 144 has opening 144b.
The thickness T of edge shield structure 144a is larger, only limited with deformability and do not have the optical cement glue of mobility
Band simultaneously cannot be inserted properly in opening 144b.
In present embodiment, using liquid optical cement 130 ', it is open in 144b with inserting.Liquid optical cement 130 '
Flowable property can at normal temperatures be maintained.The material of liquid optical cement 130 ' can be with the material of optical cement adhesive tape
Difference, it can include photosensitizer, be irradiated by light (such as UV light) and solidify.

The thickness of band.The thickness of liquid optical cement 130 ' can be about 100 microns to about 200 microns, for example
About 150 microns.The thickness of liquid optical cement 130 ' should be designed equal to or more than edge shield structure 144a
Thickness T, so that liquid optical cement 130 ' can fill up opening 144b.
Referring concurrently to Fig. 3 D and Fig. 3 E, through liquid optical cement 130 ', by first assembly 110 and second group
Part 140 is fitted.More precisely, the first adhesion coating 120 and the second component 140 are arranged at liquid optical cement
130 ' both sides, and fit each other through liquid optical cement 130 '.In this, can solidify through illumination methods
Liquid optical cement 130 ', such as using the molecular structure of UV photo damages liquid optical cement 130 '.Due to optics
Glue adhesive tape has smoother surface, therefore contacts with liquid optical cement using optical cement adhesive tape, and makes liquid
State optical cement has smoother surface S3 because of the extruding of optical cement adhesive tape.After laminating step, light
Learning glue adhesive tape becomes the first adhesion coating 120, and the second adhesion of solid-state is converted into after liquid optical cement 130 ' is cured
Layer 130, you can obtain the contactor control device 100 painted such as Fig. 2.
The present invention one or more embodiments in, should suitably select protective layer 112, optical cement adhesive tape,
The material of liquid optical cement 130 ', makes protective layer 112, the first adhesion coating 120 and the second adhesion coating 130
Refractive index sequentially successively decrease or be incremented by.
In the structure configuration of contactor control device 100, as it was previously stated, the thickness of the second adhesion coating 130 is more than the
The thickness of one adhesion coating 120, the thickness of the first adhesion coating 120 is more than the thickness of protective layer 116.First glues
Layer 120 can insert the groove 112a of protective layer 112, to avoid because the non-smooth surface of protective layer 110
S1, and produce bubble.
Fig. 4 is the profile of the contactor control device 100 of a further embodiment according to the present invention.Present embodiment
Substantially similar to the embodiment of Fig. 2, difference is：In present embodiment, transparency carrier 114 is support plate,

Glue adhesive tape is formed, and the second adhesion coating 130 can be cured by liquid optical cement and be formed.By this two kinds of differences
Adhesion coating design, one comes because liquid optical cement has the flowable characteristic of liquid in processing procedure, and can
To insert the opening 144b of edge shield structure 144a, edge shield structure 144a and panel assembly 142 are filled up
Between larger difference in height, to prevent bubble.Two, protective layer 112, the first adhesion coating 120 and
The refractive index of the second adhesion coating 130 is sequentially successively decreased or is incremented by, and can be reduced refractive index and be mismatched produced asking
Topic.
The contactor control device 100 of present embodiment can be used alone, and can also be combined and conduct with display floater
Touch control display apparatus are used.The other structures details of contactor control device 100 of present embodiment is generally such as aforementioned reality
Apply described in mode, and its manufacture method is generally similar to the manufacture method of Fig. 3 A to Fig. 3 E, here is no longer
Repeat.
The present invention provides a kind of contactor control device, and it passes through the adhesion coating for arranging two-layer different qualities, with tool of fitting
There are the first assembly and the second component on out-of-flatness surface.By this configuration, on the one hand, the refraction of the first adhesion
Rate is more nearly the refractive index of the protective layer with out-of-flatness surface than the refractive index of the second adhesion coating, can reduce
Refractive index difference between two surfaces bonded to each other, to improve the problem of rainbow stricture of vagina, on the other hand, second glues
The non-smooth surface that layer is attached at the second component entirely, can be fitted and be filled up possible difference in height on the second component
It is different, in order to avoid produce bubble.
Although the present invention is disclosed above with numerous embodiments, so it is not limited to the present invention, any
Those of ordinary skill in the art, without departing from the spirit and scope of the present invention, should make various variations with
Modification, therefore protection scope of the present invention is when by being defined that claims are defined.
