Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a panel protection window, a portable terminal including the same, and a method of manufacturing the same.

The present invention relates to a panel protection window and a portable terminal including the same. In addition, the present invention relates to a method of manufacturing a panel protection window.

Various types of portable terminals have been provided due to the development of wireless communication technology. In recent years, the display of the portable terminal tends to be large, and conversely, the thickness of the portable terminal tends to be small. Of course, very high reliability is required not only in electrical characteristics but also in mechanical properties.

There are many examples in which the display of the portable terminal substantially forms the external shape of the portable terminal. Therefore, it is necessary to prevent the display from being damaged due to dropping during use or impact with the outside.

In recent years, displays have been applied not only to PDAs, mobile communication terminals, navigation and camera displays but also home appliances such as refrigerators. For convenience, the use of touch screens or touch panel switch-based displays .

A window can be used to protect such a display. That is, a window may be used to protect the LCD or LED display panel. Of course, various types of windows may be used to protect the LCD or the touch screen provided on the LED display panel.

A conventional panel protection window W will be described in detail with reference to FIG.

First, a screen printing layer 1 is formed, and a deposition layer 20 is formed on the screen printing layer 1. A UV pattern layer 3 may be formed on the deposition layer 2 and a PET base film 4 may be provided on the UV pattern layer 3.

An adhesive layer 5 is provided on the optical ground film 4 so that the optical ground film 4 or the like is adhered to the tempered glass 6 through the adhesive layer 5.

Therefore, the panel protective window W is formed by sequentially laminating the tempered glass 6, the adhesive layer 5, the optical ground film 4, the UV pattern layer 3, the vapor deposition layer 2 and the screen printing layer 1 ) Are stacked and formed. That is, the panel protection window W has at least six layers.

Since the panel protection window W has many layers, there is a problem that the manufacturing process is very complicated and manufacturing is not easy. In addition, since the thickness of the window increases, the thickness of the entire display or the thickness of the portable terminal to which the window is applied is limited.

On the other hand, the UV pattern layer 3 is provided for window design. That is, it is possible to design various displays by forming various patterns in the UV pattern layer. For example, it is possible to form a metallic blue hue, and it is possible to implement a hairline-like design through a UV pattern layer. Therefore, the front of the display is different from the typical color and design such as black or white, and various colors and designs are possible.

In addition, letters, figures and the like can be expressed through the screen printing layer (1). For example, it is possible to implement a company logo, a button symbol or the like through the screen printing layer 1.

However, as described above, various layers are provided between the UV pattern layer 3 and the tempered glass 6. In addition, various layers are also provided between the screen printing layer 1 and the tempered glass 6. That is, a gap having a considerable distance can be formed between the UV pattern layer 3, the screen printing layer 1, and the tempered glass 6.

Therefore, it may be difficult to recognize the UV pattern layer 3 and the screen printing layer 1 from the outside. In some cases, the gap can be visually recognized from the outside, which results in a problem that product reliability is deteriorated.

In addition, the impact resistance may be reduced due to the optical ground film (4). That is, an external force applied to the tempered glass 6 may not be absorbed through the optical ground film 4. It can be said that most of the external force is absorbed by the tempered glass 6, and the impact resistance is lowered.

Meanwhile, the window W may be manufactured through the following process.

First, a very thin hard coating layer may be formed on the optical ground film 4 for scattering prevention. Then, the UV pattern layer 3 on which the pattern is formed is adhered to the lower part of the optical ground film 4. A vapor deposition layer 2 corresponding to a rim of the display is formed below the UV pattern layer 3, and a printing layer 1 is formed thereafter.

The optical ground film 4, the UV pattern layer 3, the vapor deposition layer 2, and the printing layer 1 can be produced in the form of a single sheet. After the pressure sensitive adhesive such as OCA or PSA is adhered onto the sheet, the sheet is adhered to the tempered glass 6. [ That is, through the laminating process, the sheet can be laminated with the tempered glass 6.

Therefore, it is not easy to manufacture a sheet which can be applied to various types of tempered glass with a very complicated process. This is because, since various types of through regions can be formed in the tempered glass, there may arise a problem in which the portions corresponding to the through regions in the sheet must be cut again.

In addition, there is a problem that the defective ratio is increased through the laminating process. This is because a very precise lamination process is required due to the penetration area.

U.S. Patent Application Publication No. US2012 / 0204459 (published on Aug. 16, 2012) Korean Registered Patent No. 10-1281189 (Registered on Feb. 23, 2013)

SUMMARY OF THE INVENTION The present invention basically aims to solve the problem of the conventional panel protection window described above.

It is possible to reduce the thickness of the UV pattern layer 30 or the screen printing layer 10 as much as possible by bringing the UV pattern layer 30 and the screen printing layer 10 into close contact with the glass as much as possible and thus to effectively prevent projection, ≪ / RTI >

Through the embodiments of the present invention, it is intended to provide a panel protection window, a portable terminal including the same, and a method of manufacturing the window, in which the UV pattern and the visibility of the printed contents are improved easily.

It is an object of the present invention to provide a panel protection window, a portable terminal including the panel protection window, and a method of manufacturing the window, which can significantly reduce the defective ratio during manufacture and improve reliability.

According to an embodiment of the present invention, there is provided a panel protection window, a portable terminal including the same, and a method of manufacturing the window, which improves impact resistance and reliability.

According to an embodiment of the present invention, there is provided a panel protection window capable of omitting an optical ground film and omitting a laminating process, thereby remarkably reducing a manufacturing cost, a portable terminal including the same, and a method of manufacturing the window do.

According to an embodiment of the present invention, there is provided a method of manufacturing a semiconductor device, comprising: applying a UV resin directly adhered to a glass substrate; A pattern layer forming step of forming a UV pattern layer through a mold in which a turn is formed; A curing step of curing the UV pattern layer to directly adhere the UV pattern layer to the lower surface of the glass; And a separating step of separating the base glass and the adhered UV pattern layer from the mold.

The curing step may comprise a UV curing step via UV irradiation.

The curing step may include a heat curing step through heating.

The UV curing step and the heat curing step may be performed sequentially. In addition, a predetermined interval may be provided between the UV curing step and the heat curing step.

The UV resin is a mixture of a UV curable resin and a thermosetting resin, and the weight% of the UV curable resin is greater than the weight% of the thermosetting resin. After the UV curing step, the thermosetting step may be performed.

In order to improve the adhesion of the UV pattern layer on the lower surface of the glass, the surface of the glass may be surface-processed to have a different surface roughness from the upper surface of the glass.

The pattern layer forming step may include a pressing step of pressing the glass so that the glass and the mold are more closely contacted through the roller. It is preferable that the roller directly presses the mold. This can minimize damage to the glass.

The pattern layer forming step may include a cleaning step of vacuum-sucking the UV resin overflowed during or after the pressing step.

After the separating step, it may include a heat curing step through heating. This thermal curing step can be carried out through a drying step.

It is preferable to apply the UV resin to the mold having the pattern formed in the applying step.

In the pattern layer forming step, it is preferable that the UV resin is adhered to the glass by rolling on the mold.

According to an embodiment of the present invention, there is provided a display panel, a touch screen pad provided on the panel, and a method of manufacturing a window provided on the pad to protect the panel and the pad, An application step of applying an UV resin directly adhered to the lower surface of the glass; A pattern layer forming step of forming a UV pattern layer through a mold in which a turn is formed; Curing the UV resin by irradiating the UV pattern layer with UV to cause the UV pattern layer to be directly adhered to the bottom surface of the glass; A separating step of separating the glass and the adhered UV pattern layer from the mold; And a heat curing step of curing the UV resin to improve the adhesion of the UV pattern layer by heating the UV pattern layer after the base separating step.

It is preferable that the UV resin is a mixture of a UV curable resin and a thermosetting resin, and the weight% of the UV curable resin is larger than the weight% of the thermosetting resin.

In order to improve the adhesion of the UV pattern layer to the lower surface of the glass before the application step, a surface processing step of processing the upper surface of the glass so as to have a different surface roughness may be performed.

The pattern layer forming step may include a pressing step of pressing the glass so that the glass and the mold are more closely contacted through the roller.

It is preferable that the pattern layer forming step includes a cleaning step of removing the UV resin overflowed during the pressing step or after the pressing step by vacuum suction. Through this cleaning step, it is possible to prevent the formation of a UV pattern layer in a specific region in the glass.

It is preferable that the UV pattern layer is formed by curing and adhering to each glass. In this way, when the shape or structure of the glass is changed or the pattern is changed, elasticity can be applied only by deformation of the mold.

To achieve the above object, according to an embodiment of the present invention, A UV pattern layer directly formed on the lower surface of the glass; An evaporation layer formed on a lower surface of the UV pattern layer; And a printing layer formed on the lower surface of the deposition layer.

That is, it is possible to prevent adhesion means such as OCA or the like, a ground film for diffusing and reflecting light, and the like between the glass and the UV pattern layer. Therefore, the thickness of the window can be remarkably reduced, the manufacturing process can be simplified, the manufacturing can be facilitated, and the manufacturing cost can be reduced. Therefore, it is possible to manufacture a window having a significantly low defect rate. This means that a large amount of windows are required to produce a remarkable effect.

The UV pattern layer may be formed by directly curing the UV resin applied directly on the lower surface of the glass and directly adhering to the lower surface of the glass. That is, it is possible to form a UV pattern after directly applying a UV resin to the glass.

On the other hand, it is also possible that the under surface of the glass is directly adhered to the coated UV resin. That is, the UV pattern layer may be formed by directly adhering the lower surface of the glass onto the surface of the applied UV resin, then directly adhering to the lower surface of the glass after the UV resin is cured.

Specifically, the pattern of the UV pattern layer may be formed by pressing the UV resin between the glass and the mold where the pattern is formed. That is, a UV resin layer is formed between the glass and the mold to form a pattern, and the UV pattern layer can be directly adhered to the glass.

The application of the UV resin is important in a quantitative application. This is because a UV pattern layer of uniform thickness must be formed substantially all over the lower surface of the glass. In addition, it is necessary to exclude such UV pattern layer formation in a part of the bottom surface of the glass (for example, the through hole). Therefore, it is preferable that the UV resin is applied to a mold, not to a glass. This is because it is not easy to avoid a part such as the through hole in the process of applying the UV resin to apply.

The glass includes a window region and a bezel region, and the UV pattern layer is preferably formed on the window region and the bezel region. Thus, it may be possible to implement a beautiful design for the window and the entire display.

As described above, it is preferable that the glass includes a through area such as a through hole, and formation of the UV pattern layer in the through area is excluded. The through holes may be provided for configurations such as buttons, microphones, speakers, and the like provided on the display.

The UV resin preferably comprises at least two resins with different curing properties. These different curing properties allow different curing mechanisms to be utilized. In addition, it becomes possible to cure the UV pattern layer through different hardening mechanisms at intervals of time.

Specifically, the UV resin may be a mixture of a UV curable resin and a thermosetting resin. Therefore, it becomes possible to adhere the UV pattern layer more firmly to the glass through different hardening mechanisms. This is because different tissues, rather than a single tissue, are produced through different hardening mechanisms, and these tissues can synergistically interact with one another to further improve adhesion.

The surface of the glass can be surface-treated by plasma discharge treatment or corona discharge treatment to improve the adhesion of the UV resin. That is, it is possible to artificially generate a very fine surface roughness, thereby further improving the adhesion. This is because the surface roughness can increase the surface area of the adhesive between the glass and the UV resin, and the adhesive surface can be finely formed in a wide variety of directions. Such surface roughness can act synergistically with the above-mentioned different curing mechanisms to further improve the adhesive force.

According to an aspect of the present invention, there is provided a display device including a display panel, a touch screen pad provided on the panel, and a window provided on the pad to protect the panel and the pad, Wherein the window comprises: a glass substantially forming an outer surface of the portable terminal; A UV pattern layer directly formed on the lower surface of the glass; An evaporation layer formed on a lower surface of the UV pattern layer; And a printed layer formed on the lower surface of the deposition layer.

The UV pattern layer is preferably directly adhered to the glass by curing of the applied UV resin.

The UV pattern layer can be directly applied to the glass by UV curing and thermosetting of the applied UV resin.

The UV resin preferably comprises at least two resins with different curing properties. Specifically, the curing properties include thermosetting properties and UV curing properties, and thermal curing can be performed after UV curing. Therefore, it is preferable that the UV resin is a mixture of a UV curable resin having a UV curing property and a thermosetting resin having a thermosetting property.

In order to improve the adhesive force of the UV resin, the surface of the glass is preferably surface-processed so as to have a different surface roughness from the upper surface of the glass.

To achieve the above object, according to an embodiment of the present invention, And a UV pattern layer formed directly on the lower surface of the glass, wherein the UV pattern layer is formed by sequentially applying the applied UV resin to the lower surface of the glass by UV curing and thermosetting, and And a portable terminal including the same can be provided.

The present invention can provide a panel protection window and a portable terminal including the same.

It is possible to reduce the thickness of the UV pattern layer 30 or the screen printing layer 10 as much as possible by bringing the UV pattern layer 30 and the screen printing layer 10 into close contact with the glass as much as possible and thus to effectively prevent projection, Can be provided.

Through the embodiments of the present invention, it is possible to provide a panel protection window, a portable terminal including the same, and a method of manufacturing the window, in which the UV pattern and the visibility of the printed contents are improved easily.

Through the embodiments of the present invention, it is possible to provide a panel protection window, a portable terminal including the window, and a method of manufacturing the window, which can significantly reduce the defective rate during manufacture and improve reliability.

6 is a flowchart illustrating a method for manufacturing a panel protection window according to an embodiment of the present invention.

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

First, a panel protection window according to an embodiment of the present invention will be described in detail with reference to FIG.

The panel protection window 100 may include a glass 60. The glass itself may include tempered glass having impact resistance or heat resistance. The glass may substantially form an outer surface of the display. In many cases, the display may form part of the outer surface of the portable terminal or other devices. Therefore, it is necessary to provide a foolproof design because the panel protection window 100 forms an outer surface of the devices.

For this purpose, it is preferable that the UV pattern layer 30 is directly formed on the bottom surface of the glass 60. That is, it is preferable that the UV pattern layer 30 is formed directly on the glass 60 by excluding the pressure-sensitive adhesive such as PSA or OCA and self-curing the UV resin.

The deposition layer 20 and the printing layer 10 may be formed under the UV pattern layer 30.

The UV pattern layer 30 may be formed by directly curing the UV resin coated on the lower surface of the glass 60 and directly adhering to the lower surface of the glass. However, as will be described later, it may be necessary to exclude the UV pattern layer 30 in a part of the lower surface of the glass 60. Therefore, it may be undesirable to apply the UV resin directly to the glass 60 in some cases.

The UV pattern layer 30 may be directly adhered to the lower surface of the glass after the UV resin layer is cured and directly adhered to the lower surface of the UV resin layer.

That is, the UV resin can be directly applied to the glass 60 or applied to other objects. However, in any case, the UV pattern layer 30 is directly adhered to the lower surface of the glass 60.

Here, a mold may be required to form the pattern of the UV pattern layer 30. That is, a certain pattern is formed on the mold, and such a pattern is displayed on the UV pattern layer 30.

As shown in Fig. 3, the glass 60 may be in close contact with the mold. That is, a coated UV resin may be interposed between the glass 60 and the mold 200. This UV resin is cured to form the UV pattern layer 30. Therefore, as the glass 60 and the mold 200 come into close contact with each other, the UV resin is brought into close contact with the glass 60 and the other surface is brought into close contact with the mold.

A pattern is engraved on one surface 210 of the mold. Therefore, as the UV resin before being cured is brought into close contact with the one surface 210 of the mold engraved with the pattern, the pattern can be projected onto the UV resin as it is.

This adhesion can be achieved through rolling through the roller (400). That is, the pressing can be performed through rolling. The glass 60 may be introduced into the mold through a conveying means 300 such as a picker. The glass 60 can be supported through the picker or the like. In addition, the roller 400 presses the mold 200. Accordingly, the mold 200, the UV resin, and the glass 60 can be more closely adhered between the roller 400 and the picker, and the pattern of the mold 200 can be projected onto the UV resin. That is, it can be said that the pattern of the UV pattern layer is formed by pressing the UV resin between the glass and the mold 200.

In the above, an example in which the UV resin is applied to the mold to form the UV pattern layer has been described with reference to FIG. However, UV resin may be applied directly to the glass 60 to form a UV pattern layer.

For example, the mold and the glass can be placed in the inverted form of FIG. In this case, the glass will be located at the top. Therefore, the UV resin is applied to the bottom surface of the glass, and the mold 200 can move and cover the glass. Thereafter, the UV pattern layer 20 may be formed in the same form through rolling or the like.

However, as shown in FIG. 5, the glass 60 may have various through regions 64 formed therein. In this case, UV resin may be applied to the penetration areas 63 and 64, so it may be preferable to apply the UV resin to the mold 200.

Specifically, the glass 60 may include a window region 61 and a bezel region 62. The window region 61 may be a region where a screen is displayed and the bezel region 62 may be an area forming at least a part of the outer edge of the window region 61.

The UV pattern layer 30 is preferably formed on the window region 61 and the bezel region. That is, it is preferable to form substantially the entire region of the glass 60. This is because the impact resistance of the glass can be improved through the UV pattern layer 30. That is, since the UV pattern layer 30 is a resin material interposed between the glass and the touch panel, the UV pattern layer 30 itself has impact resistance and impact absorbability. Therefore, it is preferable that the UV pattern layer 30 is formed substantially in the entire area of the glass 60 for improving the mechanical properties as well as improving the design characteristics.

In many cases, the glass 60 may be provided with a through area so as to have a through area 63 for a button, a through area 64 for a speaker, and the like. Therefore, it is preferable that the formation of the UV pattern layer 30 is excluded in such through regions 63 and 64. [

As described above, the UV pattern layer 30 may be formed by directly adhering to the lower surface of the glass 60. Therefore, the improvement of the adhesive strength becomes very important.

Basically, the UV resin in the molten state is adhered to the surface of the glass 60 as it is cured. In other words, it can be said that the UV resin is hardened and the UV pattern layer 30 is formed, and at the same time, it is adhered to the surface of the glass 60.

The UV resin is preferably a resin having UV curing properties. That is, the resin is preferably cured by UV irradiation. For example, urethane and acrylic UV resins may be used. The UV resin may be mixed with at least two different UV curable resins. For example, it may comprise a urethane acrylate oligomer and an acrylate monomer. Therefore, the resins of different tissues can be cured with a slight difference by UV irradiation. That is, by mixing different materials, it becomes possible to further increase the adhesive force through curing.

The UV resin may include an initiator to initiate polymerization of the UV cured resin.

On the other hand, the UV resin may be a mixture of a plurality of resins having different curing properties as well as different materials. That is, the resin may be a mixture of a UV curing resin and a thermosetting resin. For example, the thermosetting resin may be an epoxy resin. Therefore, the curing time can be different from each other due to the difference in the curing properties.

For example, it is possible to cure the UV curable resin through UV irradiation, and then cure the thermosetting resin through heating. Therefore, due to the difference in microstructure due to the difference in the material itself, due to the difference in curing time, the two exhibit a synergistic effect for increasing the adhesive strength to each other.

On the other hand, an excessive increase in heating temperature and an increase in heating time for thermal curing may cause problems such as a rise in manufacturing cost and deformation of glass. Therefore, the weight percentage of the UV curable resin and the thermosetting resin needs to be appropriately considered.

The present inventors have found that the weight% of the UV curable resin is 80 or more and the weight percentage of the thermosetting resin is 5 to 10 or so. That is, in consideration of the prevention of the deformation of the glass and the increase of the adhesive force, it was found that the weight percentage of the thermosetting resin is preferably 10 or less. It has also been found that the UV cured resin also preferably comprises at least two resins.

It is necessary to process the surface of the glass in order to increase the physical adhesion force in addition to the increase in the adhesion force through the difference in the curing properties. That is, it may be necessary to perform surface processing on the lower surface of the glass in order to increase the adhesion area.

For example, fine roughness can be formed on the surface of the glass by plasma discharge treatment or corona discharge treatment. A UV resin in a molten state can be drawn and cured on such a glass surface. That is, the adhesive area increases, and the direction in which the adhesive is applied can be formed in various ways. Therefore, the UV pattern layer 30 can be adhered to the surface of the glass 60 more firmly.

Meanwhile, the window 100 may be used in a portable terminal. The portable terminal may include a display panel and a touch screen panel or pad provided on the panel. The window 100 may be provided on the touch screen panel or pad to protect the display panel or the touch screen panel.

Accordingly, the window 100 substantially forms the outer surface of the portable terminal.

A portable terminal such as a smart phone can be formed as a whole window 100 on one side. Therefore, the probability that an external impact will be transmitted to the window 100 is very high. However, as described above, since the UV pattern layer 30 is directly adhered to the lower surface of the glass 60, the impact resistance is very excellent.

By omitting the adhesive means such as PSA and OCA and omitting the PET film, it becomes possible to secure thermal stability, acid resistance, solvent resistance and resistance to hot water. That is, the UV pattern layer 30 can be firmly adhered to the glass 60 even in a severe use environment.

Hereinafter, a method of manufacturing the window 100 will be described in detail with reference to FIG.

First, step (S1) of applying UV resin is performed. The construction of the UV resin has been described above, and the application can be done directly to the window 100 or directly to the mold. However, in any case, the application step (S1) is to apply UV resin for directly adhering to the lower surface of the glass.

After the application step S1, a pattern layer forming step S2 for forming a UV pattern layer through a mold having the pattern formed thereon may be performed.

Specifically, the pattern layer forming step S2 may include a pressing step of pressing the glass and the mold so as to be closer to each other through the roller. Through this pressing step, the pattern engraved on the mold can be inscribed in the UV resin, and a UV pattern layer having a uniform overall thickness can be formed on the glass.

The pattern layer forming step S2 may include a cleaning step of removing the UV resin overflowed during or after the pressing step.

As described above, it is preferable that the UV pattern layer according to this embodiment is not made in the form of a sheet. That is, it is preferable that the UV pattern layer is directly adhered to each of the glasses. Therefore, it is possible to easily form the UV pattern layer even if the shape of the glass, the presence or absence of the penetrating region, and the like are different. It is also possible to omit the step of cutting the sheet or the like.

The overflow may occur in the rim or through region of the glass. This is because the shape of the rim of the glass may be a complex shape having a groove and a protrusion rather than a general square. Such an overflow may result in a uniform formation of a UV pattern layer, and may cause contamination of a rim portion or a penetration region. In addition, a uniform UV pattern layer at such portions may not be formed. Therefore, it is necessary to effectively clean such overflowed UV resin before curing.

Such cleaning can be performed by vacuum suction of the overflowed UV resin, and a detailed description will be given later.

After the pattern layer is formed through the cleaning step, a curing step (S3) in which the UV pattern layer is adhered to the glass can be performed. That is, the curing step (S3) may be performed in which the UV pattern layer before curing is cured and the UV pattern layer is directly adhered to the lower surface of the glass.

Of course, it is also possible that the cleaning step is performed at the beginning of the curing step S3. That is, once curing begins in the window or border area, the UV resin in this area will be minimally affected by vacuum suction in the rim or through area. Thus, it may be possible to effectively clean the overflowed UV resin in the rim area or the penetration area through vacuum suction after the initial curing has started.

The curing step (S3) may comprise a UV curing step through UV irradiation. In addition, the curing step (S3) may include a heat curing step through heating. The heating may be performed by applying a microwave.

On the other hand, as described above, the UV resin may be a mixture of a UV curable resin and a thermosetting resin. Here, it is preferable that the weight% of the UV curable resin is larger than the weight% of the thermosetting resin.

In addition, the UV curing step and the thermosetting step may be performed sequentially. For example, a thermal curing step may be performed after the UV curing step is performed. This curing step S3 may be performed before the window 100 is separated from the mold. However, as described later, the thermosetting step may be performed after the window 100 is separated from the mold.

After the curing step (S3), in particular the UV curing step, is carried out, a separation step (S4) of separating the window (100) or glass and the UV pattern layer integrated with the glass from the mold can be performed.

After the separating step S4, the drying step S5 may be performed. In this drying step S5, it is possible to further cure the UV pattern layer through heating. That is, a thermal curing step may be performed after the separation step S4. Therefore, different curing conditions can be performed sequentially and at predetermined intervals. This different curing mechanism makes it possible to more firmly adhere the UV pattern layer to the glass.

On the other hand, a step S0 of machining the surface of the glass may be performed to further increase the adhesive force. That is, the surface processing of the glass can be performed before forming the UV pattern.

After each glass surface treatment is performed, a UV pattern layer is formed directly on each glass through subsequent steps. Therefore, it is possible to manufacture a very simple and quick window compared with the conventional window making method.

In addition, the formation and adhesion of the UV pattern layer can be performed through one process. That is, when the mold and the glass are joined and separated, formation and adhesion of such a UV pattern layer can be performed. Therefore, it is possible to omit the cumbersome and complicated processes in which the sheet has to be cut and the separate adhesive means are interposed to form the UV pattern layer.

Hereinafter, the cleaning step described above with reference to FIGS. 3 and 4 will be described in detail.

When the UV pattern layer is pressed in the mold, the UV resin can overflow into the through regions 63 and 64 of the glass 60. [ If the overflowed UV resin is cured, a problem that the penetration area is clogged may occur. In addition, the UV resin overflows on the edge portion or the side surface of the glass 60 to be hardened.

In order to effectively clean such overflowed UV resin, vacuum suction may be performed.

That is, the mold may be provided with an opening 211 for vacuum suction. The opening 211 may be connected to the vacuum suction pipe 500. The openings 211 may be formed corresponding to the through regions 63 and 64 of the glass or the edge regions of the glass.

Therefore, it becomes possible to clean the UV resin overflowed through the opening 211 through the opening 211 before curing, for a very short time after the mold is adhered.

On the other hand, the UV pattern layer is cured and adhered to each glass. Therefore, when the shape, the structure and the pattern of the glass are required to be changed, the mold can be changed and applied flexibly.

FIG. 4 shows an embodiment different from FIG.

As shown in the figure, the shape of the mold 200 may be formed to correspond to the contour of the glass 60. When the through holes 63 and 64 are formed in the glass 60, protrusions 212 corresponding to the through holes 63 and 64 may be formed in the metal mold 200. Therefore, a UV pattern layer is not formed at a portion corresponding to the protrusion 212.

UV resin overflowing may be generated at the rim of the protrusion 212 or the mold 200 by pressurization. That is, by pressurization, the UV resin can overflow to the upper surface of the glass 60 through the through region and the rim portion. Therefore, the UV resin overflowing through the vacuum suction pipe 500 can be vacuum-sucked from this portion.

Therefore, contamination of the upper surface of the glass 60 forming the outer surface of the portable device or the like can be prevented. This vacuum suction can be performed before the UV resin is cured, so that the overflowed UV resin can be effectively removed.

The preferred embodiments of the present invention have been described above. It is to be understood that the invention is not to be limited to the disclosed embodiment, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
