When the surface coating is coated on the outer cover plate or the conductive layer of the touch control panel, the touch control panel is easy to clean, can resist greasy dirt, can prevent fingerprint generation, and has excellent anti-glare properties by virtue of the excellent hydrophobicity and oleophobic property of the surface coating.
Description
Technical field
The contact panel that the present invention relates to a kind of topcoating and use this topcoating coating, particularly a kind of contact panel that possesses the topcoating of hydrophobicity and oleophobic property and use this topcoating.
Background technology
Compared to traditional input unit; Contact panel is available for users to directly use finger that electronic installation is carried out various instructions with the mode of intuitive operation; And then good human-computer interaction performance is provided, and possess simultaneously that operating speed is fast, tolerance range is high and advantage such as volume is little.Therefore, contact panel replaces like input units such as keyboard, mouses gradually, is widely used in like consumption electronic products such as PC, device for mobile communication, portable electronic device or e-book.Present stage, contact panel most on the market uses resistance-type and two big types of induction technologies of condenser type.
With electric resistance touch-control panel, its structure mainly comprises two indium tin oxides (Indium TinOxide, be called for short ITO) film and a plurality of point-like spacer, and this point-like spacer is positioned between this ito thin film, it is separated and keeps certain distance.When pressing this ito thin film, the user will produce conducting.At this moment, sensor can obtain pressing the coordinate of position by resistance change.Yet, because electric resistance touch-control panel uses ito thin film, shortcomings such as transparence is not good, not scratch resistance that it has, and press for a long time and make easily that also ito thin film deforms.
The development of capacitance type touch-control panel is for improving above-mentioned shortcoming; It can be divided into surface-type and projection type according to the structure difference; The former comprises that a glass baseplate and is located at the conduction plated film on this glass baseplate; Cover by an electrode pattern and an abrasion resisting layer in regular turn again on this conduction plated film; This kind contact panel provides voltage in four corners and forms uniform electric field in the surface, and when user's finger touches can cause electric field change during to panel, unit can be learnt touch position through the size of current ratio in detection corner.The latter is provided with one to be processed and be the electrode layer of arranged by ITO on a glass baseplate, when panel is pressed by the user, the electric capacity of this electrode layer will change, and can detect touch position thus.
No matter use which kind of contact panel of being developed of technology, the user all directly contact surface plate surface input order perhaps operate and the surface that dust that the user points or oil stain will adhere to contact panel easily, and possibly stay fingerprint or vestige.Therefore, will produce dirtyly, and and then influence the appearance of contact panel, and cause the user to be difficult for the information of distinguishing that contact panel shows, also possibly cause the decline of Operational Figure Of Merit in contact panel.In addition, under strong illumination, specular surface causes dazzle to let the user can't read contact panel institute picture displayed smoothly easily.
Summary of the invention
Main purpose of the present invention; Be to provide a kind of topcoating that has hydrophobicity and oleophobic property effect concurrently; After this topcoating is coated traditional contact panel surface, easy residual contaminants in the time of can overcoming traditional contact panel because of operation, and influence its outward appearance and cause the user to be difficult for differentiating the problem of demonstration information and sensitivity decline; In addition, also can solve traditional contact panel produces dazzle easily under high light problem.
Second purpose of the present invention is to provide a kind of aforementioned contact panel that has the topcoating of hydrophobicity and oleophobic property concurrently that is coated with, and this contact panel includes one and supplies the conductive layer of this topcoating coating.
The 3rd purpose of the present invention is to provide another kind to be coated with the aforementioned contact panel that has the topcoating of hydrophobicity and oleophobic property concurrently, and this contact panel includes one and supplies the outer cover plate of this topcoating coating.
For reaching above-mentioned purpose, the present invention provides a kind of topcoating that has hydrophobicity and oleophobic property effect concurrently, and this topcoating includes a nano particle suc as formula chemical structure shown in (I):
Wherein, R
1For being selected from the group that is formed by halogen, hydrogen, alkyl, alkoxyl group, hydroxy, thiazolinyl, alkynyl, acyl group, aromatic base, carboxyl, carbalkoxy and fragrant oxygen carbonyl, R
2It is a fluoro-containing group.
Further, said R

5The group that is formed.
Further, said R
2The group that fluorine polyamide-based, fluorine are polyimide-based in order to be selected from, fluoro benzoyl, fluoroalkyl, fluorine are silica-based, methyl fluoride, 3-chloro-4-fluoroanilino, perfluoroalkyl alcohol ethoxy and the hot sulfonamido of N-perfluor are formed.
Further, said R
2Be Fn, n is the integer greater than 1.
Further, the particle diameter of the nano particle of chemical structure shown in the said formula (I) is between between the 100nm to 200nm.
A kind of contact panel, said contact panel are coated with the aforementioned topcoating that has hydrophobicity and oleophobic property concurrently, and include the aforementioned conductive layer that has the topcoating coating of hydrophobicity and oleophobic property concurrently of a confession.
Further, the material of said conductive layer is to be selected from the group that is made up of tin indium oxide, antimony tin, aluminum zinc oxide and indium zinc oxide.
A kind of contact panel, said contact panel are coated with the aforementioned topcoating that has hydrophobicity and oleophobic property concurrently, and include the said outer cover plate that has the topcoating coating of hydrophobicity and oleophobic property concurrently of a confession.
Further, the material of said outer cover plate is to be selected from the group that is made up of glass, polymethylmethacrylate, SE, polycarbonate, polyethyleneterephthalate and pi.
Hence one can see that, the invention provides a kind of topcoating that has hydrophobicity and oleophobic property effect concurrently, and this topcoating includes a nano particle suc as formula (I):
Wherein, R
