Abstract
The invention belongs to technical field of touch control, it is provided that a kind of contact panel, the protection board of contact panel and manufacture method thereof.Wherein, the position that protection board is corresponding in cover plate base material key zone has groove, is filled with button ink, opens at cover plate base material afterwards and stack gradually some pigmented ink layer on the region that reeded one side is corresponding with non-visible area in groove.So; each pigmented ink layer without forming hollow out in key zone; eliminate the step difference under traditional protection plate structure; when protection board is by optical cement bonding touch-control sensing electrode layer; step difference is filled up without thicker optical cement; thus greatly reduce the integral thickness of contact panel, it is achieved that lightening.Simultaneously as without step difference, the most there is not the possibility producing bubble, optimize product appearance.It addition, button ink is directly to fill in a groove, this filling process need not use web plate, directly can realize with scraper, thus reduce the tool cost in manufacturing process.
Description
Technical field
The invention belongs to technical field of touch control, particularly relate to a kind of contact panel, the protection board of contact panel and
Its manufacture method.
Background technology
Along with the development of touch technology, contact panel is more and more frivolous.It is equipped with the intelligence of operating system at present
Mobile phone or panel computer, the non-visible area below front all can carry 2 to 3 buttons.
It is said that in general, contact panel includes protection board, touch-control sensing electrode layer and bonding protection board and touches
The optical cement of control induction electrode layer.In order to form button, the conventional mode of printing of protection board is: at cover plate base
Stacking gradually the pigmented ink layer of more than two-layer or two-layer on material, pigmented ink layer forms hollow out in key zone,
To show the pattern of button, the pigmented ink layer of different layers in the stepped arrangement in both sides, key zone so that
When obtaining pressing optical cement, the air in the openwork part that key zone is corresponding is discharged as far as possible；Afterwards each coloured
Stacking button ink layer on the building sky part of ink layer and last floor pigmented ink layer.
For example, being the contact panel of black for non-visible area, it includes that the protection of key part is hardened
Structure is as it is shown in figure 1, include: cover plate base material A；It is sequentially laminated on the first black ink on cover plate base material A
Layer B1 and the second black ink layer B2, the first black ink layer B1 and the second black ink layer B2 exist respectively
Form hollow out at the C of key zone, and the first black ink layer B1 and the second black ink layer B2 are at key zone C
The stepped arrangement in both sides；It is layered in the first black ink layer B1 and the hollow-out parts of the second black ink layer B2
Point and the second black ink layer B2 on button ink layer D.
In prior art, owing to pigmented ink layer each on protection board is all formed with openwork part in key zone, and
The different stepped arrangements of pigmented ink layer, so, after having made button ink layer D, button ink
There is a step difference L between highest point and the lowest part of layer D, and this subregion is less.When using optics
Gluing when connecing protection board and touch-control sensing electrode layer, due to the existence of step difference L, if optical cement relatively thin (as
50 μm), then can there is bubble in the range of step difference L bad, so that thicker optical cement (as
75 μm～100 μm) just can overcome air bubble problem, so can cause the contact panel integral thickness cannot be thinning,
The demand that client is lightening cannot be met.
Summary of the invention
The purpose of the embodiment of the present invention is to provide the protection board of a kind of contact panel, it is intended to solve existing guarantor
Backplate by optical cement bonding with touch-control sensing electrode layer time, owing to there is step difference, need thicker light
Learn glue and overcome bubble, thus the problem that contact panel is lightening cannot be realized.
The embodiment of the present invention is achieved in that the protection board of a kind of contact panel, and described protection board is distinguished to be had
One visible area and the non-visible area adjacent with described visible area, the described non-visible area at described protection board includes:
Cover plate base material, it has a groove in the position of corresponding described key zone；
Button ink, described button ink is filled in described groove；
At least two pigmented ink layer, each described pigmented ink layer is sequentially laminated on having of described cover plate base material
The one side of described groove.
The another object of the embodiment of the present invention is to provide a kind of contact panel, including protection board, touch-control sensing
Electrode layer and for bonding described protection board and the optical cement of described touch-control sensing electrode layer, described protection
Plate is the protection board of contact panel as above.
The another object of the embodiment of the present invention is to provide the system of the protection board of a kind of contact panel as above
Make method, said method comprising the steps of:
S1: use machining or laser processing technology, the position corresponding in cover plate base material key zone to slot, with
Form groove；
S2: application scraper, directly fills button ink in groove；
S3: open reeded one side and the district corresponding with non-visible area at cover plate base material at cover plate base material
At least two pigmented ink layer is stacked gradually on territory.
In the present invention, the protection board of contact panel has groove in the position corresponding with key zone of cover plate base material,
It is filled with button ink in groove, opens reeded one side at cover plate base material afterwards corresponding with non-visible area
Some pigmented ink layer are stacked gradually on region.So, each pigmented ink layer is engraved without being formed in key zone
Sky, eliminates the step difference under traditional protection plate structure, at protection board by optical cement bonding touch-control sensing electricity
During the layer of pole, it is not necessary to step difference filled up by thicker optical cement, thus greatly reduces the integral thickness of contact panel,
Achieve lightening.Simultaneously as without step difference, the most there is not the possibility producing bubble, optimize product
Product outward appearance.It addition, button ink is directly to fill in a groove, this filling process need not use web plate,
Direct scraper can realize, thus reduces the tool cost in manufacturing process.
