Abstract
A kind of developed photosensitive resin composition being applied to panel construction of the present invention, can develop photosensitive resin composition for one kind, it contains resin, photosensitive initiator, monomer, solvent, Chinese white and dispersant；Wherein, this Chinese white is 20 ~ 45wt% in this photosensitive resin composition, this photosensitive resin composition is made to present white appearance color, one transparent substrates wherein one surface periphery is arranged at by this photosensitive resin composition, and form the panel construction with white in finish function of frame, can be applicable in the Related products such as contact panel or flat-panel screens.
Description
Technical field
The present invention is about the composition of the photosensitive resin composition that can develop, it is desirable to provide one kind can be developed photoresist group
Become thing to can be applicable in the Related products such as contact panel or flat-panel screens, black or depth can be limited to by different conventional appearance color
The disappearance of color, uses improving product outward appearance collocation property.
Background technology
It is general that contact panel has been widely used in mobile phone mobile phone, digital camera and satellite navigator etc. at present
On consumer electronics commodity, use interface in order to improve, lift input efficiency；Generally, contact panel is transparent and is configured in
Use before the display screen of these electronic goods, user can be grasped with interacting formula input according to instruction message on display screen
Make, so greatly improve between people and machine link up interface friendliness.Typical structure of touch-control panel is by a touch-control sensor
Being arranged between a top board and a substrate of insulation, is then provided with circuit in the peripheral part of overlapping board, in order to by touch-control sensing
Touch signal on device is sent to a signal processing circuit；When earlier, the assembling mode of contact panel and display screen, mostly
Suppressed in the edge of contact panel Watch glass using a cover frame, and contact panel be fixedly arranged in front of display screen and use,
And this cover frame, in addition to the purpose in order to fixed panel, also has protection contact panel Watch glass perimeter circuit and beautification
The efficiency of mounting structure.
So this kind of known touch panel assemblage structure often can derive many disappearances, and for example, the setting of cover frame can be on surface
Glass forms rugged surface, can destroy the planarization of product-forming, and when making the plate face clean wiping of inframe, easily
So that dust dirt is snapped in the gap between cover frame and contact panel Watch glass, clean sordid hygienic issues except producing
Outside, the filling accumulation in architrave gap for the dust dirt, also it is very easy to lead to contact panel that misoperation occurs, and touch surface
The line construction of plate edge is typically more fragile, and the accumulation extruding easily side by dust and dirt wadding becomes to damage, and leads to pass
Interrogate bad phenomenon, be packed in the adhesion that the dirt in architrave gap can destroy between shell and contact panel in addition, impact is anti-
Water dust-proof effect, or even cause the damage of internal electric appliance component.
The known contact panel of another kind also can stick on a decorative layer in Watch glass, and this decorative layer is typically many non-using dark color
The frame structure that conductive material is formed, in order to hide perimeter circuit below decorations Watch glass, accomplishes the touch surface of whole plane simultaneously
Plate；Only, the manufacturing process using mode of pasting is numerous and diverse, causes the chance of error also can be lifted, and this decorative layer is most during production
For black or silver color although lifting the texture of its product, but but also its appearance color is made to be restricted and not have variability.
Content of the invention
In view of this, the present invention is intended to provide one kind can be applicable in the Related products such as contact panel or flat-panel screens,
With improving product outward appearance collocation property.
For reaching above-mentioned purpose, the photosensitive resin composition of the present invention, containing resin, photosensitive initiator, monomer, solvent,
Chinese white and dispersant；Wherein, this Chinese white is 20 ~ 45wt% in this photosensitive resin composition, makes this photonasty
Resin combination presents white appearance color.
Present invention can apply in the Related product such as contact panel or flat-panel screens, wherein, this photoresist forms
Thing may be disposed at a transparent substrates wherein surface periphery, and forms the panel construction with white in finish function of frame, and also
Bridging effect can be formed to the line layer of lower section peripheral part.
