Description

Window panel for display device and manufacturing method therefor {WINDOW PANEL FOR DISPLAY DEVICE AND FABRICATION METHOD THEREOF}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a window panel for a display device and a fabrication technique thereof, and more particularly, to a display device mounted on an electronic device (eg, a home appliance, an office device), a portable terminal, etc. in the form of a display device, a touch pad, and a touch screen. A window panel for a dragon and a method of manufacturing the same.

As is well known, electronic devices such as televisions, refrigerators, washing machines, air conditioners, computers, financial ATMs, copiers, facsimiles, information display devices of facilities, multifunctional terminals and the like and mobile terminals such as mobile phones, PDAs, PMPs, portables Portable terminals such as game machines and laptop computers are generally equipped with a display device (ie, touch panel display) such as a touch pad (or touch screen) for displaying an image or providing a user interface.

In particular, in recent years, mounting of display devices (eg, LCD, OLED, etc.) having a touch pad function or a touch screen function has been widely spread as a method for a drastic improvement of a user interface for a corresponding device.

Therefore, the user can not only view desired image information through the display device of the corresponding device, but can easily and simply receive a user interface for access to a desired function through the touch function of the display device.

On the other hand, since the touch panel display provides a user interface by touching a display surface (contact surface) with a finger, a lot of contamination (such as traces of fingerprints) caused by organic materials, dust, particles, etc. occurs on the surface (for example, dust and Organic contaminants are solidified and adsorbed), and since such surface contamination impedes the visibility and operability of the device, pollution resistance and fingerprint resistance to the touch panel display are considered as one of the most important topics.

Therefore, conventionally, as part of research for preventing surface contamination of a touch panel display, it is known to use an antifouling film, and the antifouling film is classified into a case consisting of an organic compound (organic substance) and an inorganic compound ( Minerals).

Here, in the case of an inorganic substance (inorganic membrane), the metal film which consists of chromium etc. like a stainless steel is typical. In addition, in connection with the technique for producing a strong fingerprint and chemical resistance by sol-gel synthesis method, Korean Patent No. 10-0491951 (Invention name: Chromium-free organic / inorganic sol- Gel metal coatings and methods for their preparation) are disclosed.

In addition, in the case of organic materials (organic membranes), Dow Coring and a method for producing a self-assembled monomolecular membrane commonly commercialized and having a structure of C ₈ F ₁₇ (CH ₂ ) ₂ Si (OMe) ₃ : (perfluoropolyether silane) A method of tip coating or spin coating alkoxysilyl perfluoropolyether (PFPE) polymer film, a 2604 coating material is disclosed. [New Anti-Fingerprint Coatings, Steve Block et al. 11th Annual Coatings for Plastics Symposium, Chicago, IL, April, 2008.].

However, even in the case of an anti-fingerprint film, when the contact surface with contaminants is wide, staining and surface contamination to some extent are inevitable, and in the case of self-assembled monolayer films, the durability is poor due to the thinness of several nanometers. In the case of a film formed of PFPE polymer, durability is relatively good, but when it is manufactured in a flat plane, the contact area with contaminants becomes wider, so that the area of exposure to contaminants becomes wider. I was forced to accompany.

According to the present invention, by applying a fine pattern structure to the surface of a display device capable of adsorbing contaminants, the contact surface area with contaminants can be relatively reduced, so that stains or contaminations can be effectively suppressed on the surface of the display device. In addition, effective removal (desorption) of the adsorbed contaminants can be realized.

In addition, since the present invention uses a material having a relatively low surface energy as a material having a fine pattern of reducing contact surface area with contaminants, it is possible to more effectively suppress the adsorption of contaminants on the surface of the display device.

SUMMARY OF THE INVENTION In accordance with an aspect of the present invention, by applying a fine pattern structure to a surface of a display device capable of adsorbing contaminants caused by dust, organic matters, etc., the contact surface area with the contaminants is relatively reduced, thereby adsorbing stains or contaminants on the surface of the display device. By suppressing the above, the present invention can effectively solve the problems in the conventional manner through such technical means.

In addition, the present invention uses a material having a relatively low surface energy (for example, fluorinated polymer, etc.) as a fine pattern to reduce the contact surface area with contaminants, thereby further suppressing the adsorption of contaminants on the surface of the display device. It includes.

Here, the fine pattern may be formed by any one of a UV exposure process, a molding process, a fluorinated self-assembled monomolecular treatment process, a film bonding process, and a phase separation process, and the fine pattern may be a transparent window pattern of a polymer. It may be formed on the surface of the display device, that is, on the transparent substrate.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Example 1

1 is a cross-sectional view of a window panel for a display device according to Embodiment 1 of the present invention, in which a transparent window pattern 104 having an arbitrary pattern width range is formed on a transparent substrate 102. Here, the pattern width of the transparent window pattern 104 may be, for example, in the range of several micrometers to several mm in advance.

Referring to FIG. 1, the transparent substrate 102 may mean a surface of a display panel of an electronic device or a mobile terminal or a surface of a touch pad.

The transparent window pattern 104 is then a contaminant resistant material (film) and / or fingerprint material (film) and / or chemical resistant material (film) of transparent material that provides touch or display functionality for the user interface, For example, a UV curable polymer material may be used, and the UV curable polymer material may be, for example, a fluorinated polymer material such as perfluoropolyether (PFPE), polyurethane (PU), polyurethaneacrylate (PUA), or the like.

Here, the transparent window pattern 104 has a fine pattern structure in order to minimize the contact surface area with the contaminants, which is easily removed by allowing the contaminants adsorbed on the transparent window pattern 104 to be adsorbed only on a part of the pattern surface. This is to make it detachable.

For example, when a user touches (touches) a finger on the touch panel display on which the window panel for the display device of the present embodiment is formed, for example, as shown in FIG. 2, the surface of the transparent window pattern 104 is provided. Contaminants 106 (eg, when water + oil) may be adsorbed, in which case the contaminants 106 have a relatively small contact area relative to the plate. Therefore, since the contaminant 106 has a small contact area in this way, it can be easily detached.

In addition, the present embodiment uses a fluorinated polymer as the transparent window pattern 104, which has a relatively low surface energy. Therefore, in the window panel for a display device of the present embodiment, the adsorption of contaminants can be further suppressed through such characteristics.

On the other hand, the transparent window pattern 104 on the transparent substrate 102 constituting the window device for a display device of the present embodiment, for example, a UV exposure process, a molding process, a fluorinated self-assembled monomer processing process, a film bonding process, a phase separation process It can be formed through any one of the methods.

Here, the UV exposure process, for example, by forming a UV polymer material on the transparent substrate 102, and then subjected to an exposure using an exposure mask pattern to expose the polymer material through a series of processes to clean the image on the transparent substrate 102 Means a process of forming a transparent window pattern 104 having a fine pattern structure in the mold, and the molding process, for example, after forming a polymer material on the pattern surface (embossed portion) of the mold on which the pattern surface corresponding to the fine pattern is formed Refers to a process of forming the transparent window pattern 104 in such a manner that the pattern surface of the substrate is pressed into contact with the transparent substrate 102 to transfer the polymer material to the transparent substrate 102. In addition, the molding process may form the transparent window pattern 104 by transferring the polymer material to the transparent substrate 102 through a roll to roll method using a cylindrical mold.

In addition, the fluorinated self-assembled monomolecular treatment process uses a surfactant molecule composed of a reactor, an alkane chain, a functional group, and the like, and the transparent window is formed by chemically bonding between the molecules forming the surface and the film of the transparent substrate 102. The process of forming the pattern 104, and the film adhesion process, for example, by forming a patterned transparent window film and then attaching the transparent window pattern 104 to the transparent window film on a transparent substrate 102 by The process of forming a phase, and the phase separation process, refers to a process of forming the transparent window pattern 104 on the transparent substrate 102 through a phase separation technique.

The window panel for a display device according to the present embodiment having the above-described structure and manufacturing process may be, for example, a television, a refrigerator, a washing machine, an air conditioner, a computer, a financial ATM, a copy machine, a facsimile, a guide display device of a facility, a multifunctional terminal, or the like. It can be used as a touch panel display of an electronic device or as a touch panel display of a mobile terminal such as, for example, a mobile phone, a PDA, a PMP, a portable game machine, a notebook computer, and the like.

[Example 2]

3 is a cross-sectional view of a window panel for a display device according to Embodiment 2 of the present invention, wherein a transparent window pattern 304 having an arbitrary pattern width range is formed on a transparent substrate 302, and is formed on the transparent window pattern 304. Has a structure in which the wettability modifying layer 306 is formed. Here, the pattern width of the transparent window pattern 304 may be, for example, in the range of tens to hundreds of nanometers (nm), unlike the first embodiment described above.

In this embodiment, setting the pattern width of the transparent window pattern 304 to a range of tens to hundreds of nanometers (eg, a range of 400 nm or less, which is smaller than the wavelength of light) minimizes interference by light. This is to enhance the optical properties of the window panel. That is, in order to prevent the transparent window pattern formed on the transparent substrate 302 from adversely affecting optical characteristics.

Next, by performing any one of a UV exposure process, an oxygen plasma process, and a fluorinated self-assembled terminal treatment process on the entire surface of the structure on which the transparent window pattern 304 is formed on the transparent substrate 302, Wet modifying layer 306 is formed on transparent window pattern 304.

For example, a UV exposure process or an oxygen plasma treatment process may be performed to modify the surface of the transparent window pattern 304 to a wettability characteristic (that is, apply excessive energy to change the physical properties of the surface), thereby forming a surface on the transparent window pattern 304. The wettability modifying layer 306 of the thin film is formed or the fluorinated self-assembled monomolecular treatment is performed to laminate (coating) the wettability modifying material of the thin film on the transparent window pattern 304, thereby forming the film on the transparent window pattern 304. A thin wettability modifying layer 306 may be formed.

Here, forming the wettability modifying layer 306 of the thin film on the transparent window pattern 304 may be performed by touching a finger on the touch panel display on which the window panel for the display device of the present embodiment is formed, for example, for a user interface. As an example, as shown in FIGS. 4A and 4B, contaminants (eg, moisture 308 and oil 310, etc.) may be adsorbed on the surface of the transparent window pattern 304. Due to the wettability property is wetted on the surface of the transparent window pattern (304). That is, as an example, as shown in FIG. 4B, the contaminants penetrate into the intaglio portion of the transparent window pattern 304 so that no contaminants remain on the surface of the window panel.

In other words, the window panel for the display device according to the present exemplary embodiment may allow contaminants adsorbed on the surface to penetrate the intaglio portion of the transparent window pattern by improving the wettability characteristic so that no contaminants remain on the surface of the window panel.

These second transparent window patterns 506a and 506b are substantially the same as the corresponding ones (304 in FIG. 3) of Embodiment 2 described above in material, structure, function and manufacturing method. Therefore, detailed description herein is omitted in order to avoid unnecessary duplication of description for the sake of brevity of the specification.

In terms of function, manufacturing method, and the like, it is substantially the same as the corresponding one of the above-described Embodiment 2 (306 in FIG. 3). Therefore, detailed description herein is omitted in order to avoid unnecessary duplication of description for the sake of brevity of the specification.

That is, the window panel of the present embodiment forms a first transparent window pattern on the transparent substrate, and simultaneously forms a second transparent window pattern on the embossed portion surface and the intaglio portion surface of the first transparent window pattern, and the first and second By forming the wettability modification layer which modifies the surface property of a transparent window pattern, the window panel for display devices which have a target structure can be manufactured.
