Description

Manufacturing method of window for display device, display device window and portable wireless terminal having same {Manufacturing Method of Window For Display Device, Window For Display Device and Wireless Terminal Unit Comprising The Same}

The present invention relates to a window manufacturing method of a display device, a display device window, and a portable wireless terminal having the same.

Display devices such as liquid crystals and OLEDs exist in portable wireless terminals and the like, and windows are employed to protect them. Conventional windows are mainly made of acrylic resins, synthetic resin substrates such as polycarbonate (PC) or polyethylene terephthalate (PET), and the thickness of the windows according to the trend of miniaturization and slimming of portable devices. It is also getting slimmer.

However, in the case of slimming the synthetic resin substrate, there is a problem in that the strength of the synthetic resin substrate is insufficient to sufficiently protect the display device from external impact. In addition, the surface hardness is also low, there is a problem that is not free to scratch.

In order to solve this problem, it has been attempted to employ glass such as tempered glass as a window instead of a synthetic resin substrate. However, when the glass is used as a window, when the glass is subjected to an impact greater than the limit shock, the glass is scattered and causes a fatal damage to the display device.

In order to solve this problem, it has been attempted to apply the anti-scatter coating to prevent the scattering or to attach the anti-scattering film to the front or the back with a double-sided tape or a general adhesive, adhesive, or the like.

However, the above window also has the following problems.

First of all, according to the recent trend, the window is also required to be decorated in various ways. However, the direct decoration on glass is considerably more difficult than the decoration on a general synthetic resin substrate, and there are various limitations.

In order to solve the above problem,

The present inventors have studied the bonding of a decorated synthetic resin substrate and glass with a UV-adhesive. However, even when the synthetic resin substrate and the glass is bonded with a UV-adhesive, there is a problem in that air bubbles are not sufficiently removed and there is no practical use.

However, there is a concern that additional air bubbles may be generated during curing by UV irradiation, and thus, the pressure-sensitive adhesive process is not mass-producible and thus uncompetitive in terms of unit cost of the window.

That is, in order to perform the pressure-sensitive adhesive process, the process of putting the glass, the resin substrate, and the UV adhesive into a closed space (for example, a vacuum chamber) in a vacuum or semi-vacuum state and removing the window after adhesion is not simple in an automated process.

Alternatively, the degassing accelerator may be formed on both the synthetic resin substrate and the glass.

The window of the display device according to the present invention is squeezed when the resin substrate is bonded to the UV-adhesive. For a long time, the adhesion process has been studied and various attempts have been made, but air bubbles have not been satisfactorily removed.

In the meantime, when the outer periphery of the surface on which the synthetic resin substrate and the glass are bonded to each other comes into contact with each other, it has been found after endeavor that air bubbles are not removed and the air bubbles are not removed.

The inventors have led to the formation of a degassing accelerator in the synthetic resin substrate and / or glass. That is, all or a part of the edge where the synthetic resin substrate and the glass are bonded to each other are cut to form a gas removal promotion unit, and then compressed and adhered to remove air bubbles satisfactorily through the gas removal promotion unit. Thereby, even if it did not adhere | attach by the method of pressure reduction crimping, air bubble was removed and the mass productivity increased very much. In particular, the pressing method starts the pressing from one end of the window using a roll-press and proceeds gradually to the other end to obtain the result that the air bubble is remarkably effectively removed by the gas removal promoting unit.

It is formed, and all or part of the corners where the side and the side to be bonded to each other is formed by cutting. The degassing accelerator may be cut in a straight line, may be cut in a curved line, but is not limited.

In addition, the gas removal promoting unit 12 is preferably formed on all of the outer circumference when the synthetic resin substrate 10 is viewed in plan view. However, the present invention is not limited thereto, and may be formed within a range of 1 to 4 directions in the east, west, north and south directions of the outer circumference. That is, it is good to be formed in the outer periphery located in the advancing direction of a crimping | compression-bonding process, and it is good to be formed also in the side of a advancing direction. In order to simplify the process, the gas removal promoting unit may not be formed at the outer circumference opposite to the traveling direction.

FIG. 6 is a cross-sectional view of a window of a display device according to still another embodiment of the present invention, wherein the glass 30 has a degassing accelerator at a position corresponding to the degassing accelerator 12 of the synthetic resin substrate. It is characterized by. This is the same even when the glass is at the bottom of the resin substrate (not shown).

Although the window of the display device according to the present invention and the display device window manufactured by the manufacturing method described below are not limited, the total thickness is preferably in the range of 0.4 to 2.0 mm, especially 0.5 to 1.5 mm. If it is less than the above range it is difficult to sufficiently protect the display device against external shock due to the strength, and if it is more than that, it may not be desirable because it is relatively slim.

Hereinafter, a method of manufacturing a window of the display device according to the present invention will be described.

In the method of manufacturing a window of the display device according to the present invention, the step of applying a UV-adhesive to the glass 30, the step of placing the synthetic resin substrate 10 on the glass coated with the UV-adhesive 20, roll-press Passing through the 50 to gradually press the synthetic resin substrate 10 from the beginning to the end to remove the gas, and irradiated with UV to harden the UV-adhesive. In addition, the present invention may include, but is not limited to, a thermal drying process step before or after the UV irradiation process, which exhibits the same effect as the IR drying process.

On the other hand, the UV-adhesive may be applied to the synthetic resin substrate instead of the glass 30 to perform the manufacturing. That is, applying the UV-adhesive to the synthetic resin substrate, placing the glass on the synthetic resin substrate coated with the UV-adhesive, through the roll-press gradually presses the synthetic resin substrate and the glass from the end to the end Removing the gas, and irradiating UV to cure the UV-adhesive.

In the method of manufacturing a window of the display device according to the present invention, when the adhesive is bonded with a synthetic resin substrate and a UV-adhesive, it is compressed. For a long time, the adhesion process has been studied and several attempts have been made.

In the meantime, in the process of pressing, instead of pressing at the same time, instead of pressing gradually, it was found that the gas is effectively released and removed in the pressing direction and side as the pressing is performed.

In addition, even in the method of applying the UV-adhesive, if the dispersion coating is applied to a part of the adhesive region with the dispersing applicator, the air bubbles are more effectively removed and the problem of the UV-adhesive coming out during the pressing process can be eliminated.

In particular, reducing the application amount of the UV-adhesive along the pressing progress direction reduces the problem of more effectively removing the air bubble and counting the UV-adhesive.

In addition, as described above, after forming the degassing promotion part on the synthetic resin substrate or / and glass, and bonding and bonding, it was found that the air bubbles are more satisfactorily removed through the degassing promotion part. Thereby, even if it did not adhere | attach by the method of pressure reduction crimping, air bubble was removed and the mass productivity increased very much.

7 is a flowchart illustrating a window manufacturing method of a display device according to an exemplary embodiment of the present invention. Examples of the window of the display device manufactured by the manufacturing method include the above-described window, but are not limited thereto. Since the window configuration has been described in detail in the following description, a description thereof will be omitted below. For example, the plastic substrate 10 or / and the glass 30 may be provided with a gas removal promoting unit 12 even without a special description, and the glass substrate and the glass may be formed on the top or the bottom of the plastic substrate. Can be located.

Specifically, it is as follows.

First, the UV-adhesive 20 is applied to the synthetic resin substrate 10 or the glass 30.

The method of applying the UV-adhesive to the resin substrate or the glass is not limited and may use various application methods known in the art. More preferably, it is good to disperse | distribute an adhesive agent to a part of the area | region joined with the said synthetic resin substrate among the bonding surfaces of glass with a dispersing applicator. The dispersion spreader is controlled by a control device to control the discharge position and the discharge amount of the adhesive. The discharge port of the dispersion applicator may be one, but it may be made of a plurality to save the dispersion coating time. On the other hand, even when the UV-adhesive is applied to the synthetic resin substrate, the UV-adhesive is applied to the synthetic resin substrate as described above.

8 and 9 are diagrams showing an example of dispersion coating. Dispersion is applied with the dispersion applicator but is not applied to the entire area, but is preferably applied to a partial area as shown in FIG. 8. More preferably, as shown in Figure 9 it is preferable that the coating amount of the adhesive decreases in the direction in which the pressing proceeds. In addition, dispersion coating may be performed as shown in FIG. 13. That is, it is good to disperse | distribute while drawing continuously in a zigzag form in a roll press crimping direction, and it is good to reduce the application amount of an adhesive agent in the direction to which crimping advances.

In the case of the synthetic resin substrate where the pressing process proceeds, the discharge amount of the adhesive increases, and if the discharge amount decreases stepwise or gradually toward the end, the air bubble is removed more effectively and the UV-adhesive count is reduced. . Although not limited, it is preferable to adjust the discharge amount so that the thickness after UV-adhesion is in the range of 0.005 to 0.1 mm.

Next, the synthetic resin substrate 10 is placed on the glass to which the UV-adhesive is applied. Of course, when the UV-adhesive is applied to the synthetic resin substrate, the glass is placed on the synthetic resin substrate coated with the UV-adhesive. On the other hand, a UV-adhesive may be applied to both the glass and the resin substrate.

It is not required to squeeze and match the adhesive area of the glass with the resin substrate. Although not shown, the crimp start end may be positioned such that the synthetic resin substrate and the glass are in contact with each other, and the ends may be spaced a predetermined distance apart. The synthetic resin substrate 10 is preferably decorated, it is preferable that the decoration layer 11 is formed on a portion of at least one of the upper and lower surfaces of the synthetic resin substrate. Although not limited, the image display area 1 of the window may not be decorated, and may be decorated transparently or semi-transparently so that the decoration is visible when the display device is turned off and the image is visible when it is turned on.

Next, the synthetic resin substrate 10 and the glass 30 are gradually pressed from the end to the end by passing through the roll-press 50 to remove the gas.

10 and 14 are schematic diagrams of the pressing and degassing process using the roll-press 50. As shown, the glass 30 or the resin substrate 10 is positioned on the moving means 60 and then pressed into a roll-press after the above-described process. Since the roll-press 50 is squeezed gradually from the beginning to the end of the synthetic substrate and the glass, the remaining gas is discharged and removed to the side or the end when viewed in the pressing direction, thereby eliminating the problem of air bubbles. The roll-press may be rolled with its own driving force, or may be rolled naturally as the vehicle moves in contact with the resin substrate. In the drawings, the roll is formed only in the upper portion, but is not limited thereto, and a roll is formed in the lower portion. The material of the roll is not limited, and metal, plastic, rubber, or the like may be used. Elastic material is recommended to prevent damage to the product. In addition, the pressure of the roll-press is not limited and it is preferable to apply pressure such that the product is not damaged, in particular glass is not broken. The glass can withstand different pressures depending on whether it is tempered glass, so it is better to adjust it to fit well, which can be easily adjusted through repeated experiments, and thus detailed description is omitted.

When the roll press is used, pressing and gas removal may be performed while moving the moving means, and the next step may be performed. Thus, the process time may be shortened to a degree comparable to that of the conventional method.

Next, UV is irradiated to cure the UV-adhesive to manufacture a display window. There is no restriction | limiting in the UV irradiation method, A conventional method can be used. There is a photoinitiator in the UV-adhesive, so the reaction proceeds and cures very quickly. UV irradiation time is not limited, but a very thin film is a few seconds ~ minutes is appropriate.

Meanwhile, It may also include a thermal drying process step which exhibits the same effect as the IR drying process before or after the UV irradiation process.

Figure 11 is another embodiment of the present invention, any one of the synthetic resin substrate and the glass is a window shape, the other is the size of the window shape can be placed in the range of 2 to 100, of the UV-adhesive After the curing process is completed, it can be cut and produced individually.

In one example, the glass 30 may be used that is significantly larger than the window shape. That is, it is preferable to use the size that the window-shaped synthetic resin substrate 10 can be placed in the range of 2 to 100. After the synthetic resin substrate is placed on the glass by the number of windows, and after all the above-described steps, the curing of the UV-adhesive agent is completed, the individual pieces may be cut to produce windows in large quantities.

On the contrary, as shown in FIG. 15, the synthetic resin substrate 10 may be larger than the window shape, and after all the above-described steps are used using a size that can be placed in the range of 2 to 100, the windows may be cut individually and massed. It can manufacture.

On the other hand, although not shown, as another embodiment, by mounting a plurality of glass of the window shape to the assembly jig moving by the moving means to perform the respective steps, so that a large number of windows to be manufactured at the same time to make the window in large quantities It can also manufacture. The number of glasses that can be seated on the assembly jig is not limited but is preferably 2 to 20 pieces. Meanwhile, the steps may be performed by mounting a synthetic resin substrate on the assembly jig instead of glass to apply a UV-adhesive to the synthetic resin substrate and mounting the glass. The number of synthetic resin substrates that can be seated on the assembly jig is not limited but is preferably 2 to 20 pieces.

In the method of manufacturing a display device window according to the present invention, each of the steps may be controlled and programmed by the control device to perform the steps while moving by the moving means to automate the process.

By the process automation, the mass production test using the above-described methods showed that the time required for manufacturing one display window was less than 30 seconds, in particular less than 5 seconds. The measurement method averaged by measuring the time taken to manufacture 1000 display windows.

The present invention also provides a portable terminal device having the window of the display device or the window of the display device manufactured by the manufacturing method. The portable terminal device is not limited as long as the display device is provided and a window is required. The window of the display device according to the present invention may be laminated on the outer surface of the display device of the portable terminal device, and may be combined with the window coupling part of the portable terminal device (which is well known and thus not described in detail) at predetermined intervals. . In particular, in the case of a portable terminal device, an external display screen (CLI) exposed to the outside is often present, and the window of the present invention may be preferably used as a window of the external display screen.
