The double-sided coating film manufactured according to this method is capable of reducing the curl portion and film thickness that occurs in existing laminated double-sided coating films, and contains the characteristics of excellent light loss prevention function.

일반적으로 TV, 모니터 및 휴대폰등의 디스플레이 기기에 있어서 광량 제어, 광의 반짝이는 형상, 표면에서 외부의 상을 왜곡하는 등의 광량의 기능적 특성을 제공하기 위하여 디스플레이 필름을 상기 디스플레이 기기에 부착하고 있으며 최근에는 하나의 필름에 복수의 부가적인 기능을 부여하기 위하여 양면 코팅된 디스플레이 필름이 많이 사용되고 있다. 기존의 양면 코팅 필름을 제조하는 방식에 있어서는 1차 필름의 한쪽 면에 기능성 코팅, 즉 표면에서 외부의 상을 왜곡하는 기능인 AG 코팅 혹은 표면에서 반짝이는 형상을 가지도록 하는 AR 코팅, 혹은 다른 기능성 코팅 등을 수행하고 각각의 필름의 특성을 갖는 광 제어 코팅을 수행한 다음, 또 다른 2차 필름 원단에 상기 AG 코팅, AR 코팅 혹은 다른 기능성 코팅 등을 수행한 다음에 상기 1차 필름과 접착제 등을 이용하여 접착하는 방식으로 양면 코팅 필름을 제작하는 방법이 많이 사용되고 있다.In general, in display devices such as TVs, monitors, and mobile phones, display films are attached to display devices to provide functional characteristics of light volume such as light volume control, sparkling shape of light, and distortion of external images on the surface. Recently, display films have been attached to display devices such as TVs, monitors, and mobile phones. In order to provide multiple additional functions to one film, double-sided coated display films are widely used. In the existing method of manufacturing a double-sided coating film, a functional coating is applied to one side of the primary film, that is, an AG coating that distorts the external image on the surface, an AR coating that gives the surface a shiny shape, or another functional coating. After performing light control coating with the characteristics of each film, performing the AG coating, AR coating or other functional coating on another secondary film fabric, and then applying the primary film and adhesive, etc. A method of producing a double-sided coating film by bonding is widely used.
그러나 이러한 접착을 이용한 양면 코팅 제조 방법에 있어서는 하나의 양면 코팅 필름을 만들기 위해 두 장 이상의 필름을 합지하여 제조함으로 원단의 손실이 발생하고 또한 합지시 필연적으로 발생하는 컬(CURL) 현상 등으로 인해 양면 코팅 필름의 기능 및 품질에 부정적인 영향으로 간주되어왔다.However, in this double-sided coating manufacturing method using adhesion, fabric loss occurs as two or more films are laminated to make one double-sided coating film, and double-sided coating is produced due to the curl phenomenon that inevitably occurs during lamination. It has been considered to have a negative impact on the function and quality of the coating film.

By implementing a method and using this method to apply the double-sided coating film of the present technology to a display device, the curl phenomenon that inevitably occurs in the conventional technology is reduced, thereby significantly improving the quality of the film and preventing loss of the fabric. Thus, the present invention, which can implement a further improved film, was completed.

In addition, the pattern (surface irregularities) is characterized in that it can perform AG coating, which has the function of distorting the external image on the surface, AR coating, which gives the surface a shiny shape, or other functional coating. Preferably, steps B and C are performed repeatedly to produce a double-sided coating film having two or more plural patterns and/or multiple main coating layers to satisfy various customer needs. Unlike the prior art, the double-sided coating film completed according to the manufacturing method of the present invention completed in the above steps does not use two or more plurality of film fabrics to complete one double-sided coating film, but only one film fabric. By implementing a method of manufacturing a double-sided coating film using this method and applying the double-sided coating film of the present technology to a display device, the quality of the film is significantly improved by reducing the curl phenomenon that inevitably occurs in the prior art. In addition, by preventing loss of the fabric, a more improved film can be realized.
도 3은 본 발명에 따르는 양면 코팅 필름이 디스플레이 기기에 적용된 단면도를 도시한 것이다. 일반적으로 디스플레이 기기는 면발광(BLU)을 하는 발광소자 상에 LCD(Liquid Crystal Device)가 부착되어 이루어지게 되는데, 본 발명의 양면 코팅 필름이 도면에 도시된 바와 같이 면 광원과 LCD 층의 중간층에 부착될 수도 있고, 또한 LCD 상에 바로 부착될 수도 있다. 만약 상기 디스플레이 기기가 LCD 상에 글라스 기판이 증착된 구조라면 도면에 도시된 바와 같이 LCD와 글라스 층 사이에 구현될 수도 있다. 도면에 도시되지는 않았지만 글라스 기판상에 부착되는 것도 구현될 수 있다. 이러한 LCD 디스플레이 기기 외에 OLED로 구현된 디스플레이 기기에서는 OLED의 자체 발광으로 인해 면발광 소자가 존재하지 않으므로 OLED의 상단에 바로 본 발명에 따르는 양면 코팅 필름이 부착될 수도 있고, LCD 디스플레이 기기와 유사하게 OLED 상에 글라스 층이나 추가적인 다른 층이 형성되어 있다면 OLED 층과 상기 글라스 혹은 추가적인 다른 층 중간에 구현될 수도 있으며 LCD 디스플레이 동일하게 글라스 상층 혹은 추가적인 다른 층상에 형성될 수도 있다.Figure 3 shows a cross-sectional view of the double-sided coating film according to the present invention applied to a display device. In general, display devices are made by attaching an LCD (Liquid Crystal Device) to a light emitting device that emits surface light (BLU). As shown in the drawing, the double-sided coating film of the present invention is attached to the intermediate layer between the surface light source and the LCD layer. It can be attached, or it can also be attached directly on the LCD. If the display device has a structure in which a glass substrate is deposited on an LCD, it may be implemented between the LCD and the glass layer as shown in the drawing. Although not shown in the drawings, attachment on a glass substrate can also be implemented. In addition to these LCD display devices, in display devices implemented with OLED, there is no surface light-emitting element due to the self-luminescence of OLED, so the double-sided coating film according to the present invention may be attached directly to the top of the OLED, and similar to LCD display devices, OLED If a glass layer or another additional layer is formed on top, it may be implemented between the OLED layer and the glass or another additional layer, and, like an LCD display, may be formed on the top layer of glass or another additional layer.
상기와 같은 본 발명에 따르는 양면 코팅 필름 적용으로 인해 디스플레이 기기에서는 종래기술에서 필연적으로 발생하는 컬(CURL) 현상을 감소시키고 광 제어 기능을 더욱 향상시킬 수 있으며 고객의 요구에 따라 복수의 멀티 기능 필름층을 형성할 수 있으므로 더욱 개선된 디스플레이 장치를 제공할 수 있게 된다. By applying the double-sided coating film according to the present invention as described above, the curl phenomenon that inevitably occurs in the prior art can be reduced in display devices and the light control function can be further improved, and a plurality of multi-functional films can be applied according to customer needs. Since layers can be formed, a more improved display device can be provided.
도 4는 본 발명에 따르는 양면 코팅 필름의 색상 구현을 나타낸 도면이다. 양면 코팅 필름의 색상 구현은 고객의 요청에 따라 다양한 색상으로 구현될 수 있다. 색상의 경우 구현하고자 하는 색상은 색 조경 표상의 색상을 기준으로 하며 복잡한 색상의 경우는 색상 혼합물을 사용할 수 있다. 색상을 구현하는 방식의 경우 증착 방식, 염료방식 및 알료방식이 적용될 수 있으며, 어떠한 방식을 사용하더라도 무방하나 본 발명에서는 알료 방식을 바람직한 실시예로 적용하여 색상을 구현함으로써 생산비용 및 시간에 따른 변색현상을 차단하는 효과를 구현하였다. 이러한 색상 구현의 경우는 본 발명에 따르는 패턴(표면요철) 작업 후에 패턴과 패턴 사이의 부분에 색상알료를 주입하여 안정적인 색상을 구현하며 도면에 도시된 바와 같다. 양면 코팅 필름의 용도에 따라 코팅 필름의 최상층에 형성된 패턴사이에 색상을 구현하여도 일정부분의 효과는 있으나 효과가 미비할 수도 있으므로, 본 발명에서는 정면에서는 구현하고자 하는 색상이 약하고 일정 각도별로 색상이 진해지도록 구현할 수 있으며, 상기 각도는 제품의 용도에 따라 적용될 수 있으며 예로써, 20도, 25도, 27도, 30도, 33도, 35도, 45도 등으로 구현할 수 있으며 이외에도 제품의 용도에 따라 어떠한 각도로서도 구현할 수 있다. 각도의 시작은 지표면 기준 수직인 부분(90도)인 부분이 0도이다.Figure 4 is a diagram showing the color implementation of the double-sided coating film according to the present invention. The color of the double-sided coating film can be realized in a variety of colors according to customer requests. In the case of color, the color to be implemented is based on the color in the color landscape representation, and in the case of complex colors, a color mixture can be used. In the case of a method of realizing color, deposition method, dye method, and alloy method can be applied. Any method may be used, but in the present invention, the alloy method is applied as a preferred embodiment to implement color, thereby reducing production costs and discoloration over time. The effect of blocking the phenomenon was implemented. In the case of realizing this color, a stable color is realized by injecting color pigment into the area between the patterns after the pattern (surface unevenness) work according to the present invention, as shown in the drawing. Depending on the use of the double-sided coating film, even if the color is implemented between the patterns formed on the top layer of the coating film, there may be some effect, but the effect may be insufficient. Therefore, in the present invention, the color to be implemented on the front side is weak and the color is changed at a certain angle. It can be implemented to be thicker, and the angle can be applied depending on the use of the product. For example, it can be implemented as 20 degrees, 25 degrees, 27 degrees, 30 degrees, 33 degrees, 35 degrees, 45 degrees, etc. In addition, it can be implemented according to the use of the product. It can be implemented at any angle. The angle starts at 0 degrees, which is the part perpendicular to the ground surface (90 degrees).
도 5는 본 발명에 따르는 양면 코팅 필름 제조과정에서 증착 과정을 도시한 도면이다. 추가적인 기능향상을 위해 본 발명에서는 패턴 작업이 끝난 후 패턴 상에 증착 공정이 적용될 수 있다. 이러한 증착 공정은 한 번의 증착으로도 진행될 수 있고, 더욱 세부적인 기능 추가를 위해 복수의 증착 작업이 이루어질 수도 있다. 복수의 증착 작업을 통해 색상도 구현하면서 광 제어 기능도 추가적으로 부여할 수 있다. 증착 면의 경우는 본 코팅의 투명코팅 후에 상면에 진행하는 것으로 할 수 있으며, 증착 면의 표면반사 기능을 이용하여 제품을 구현할 수 있다. 이때 제품의 특성을 향상시키기 위하여 비어있는 패턴 사이의 공간에 유색으로 코팅작업을 수행하여 반사율을 향상 시킬 수도 있으며, 이러한 과정을 통해 형성되는 양면 코팅 필름의 단면도는 도 5에 도시된 바와 같다.Figure 5 is a diagram showing the deposition process in the manufacturing process of the double-sided coating film according to the present invention. In order to further improve functionality, in the present invention, a deposition process can be applied on the pattern after the pattern work is completed. This deposition process can be performed with a single deposition, or multiple deposition operations can be performed to add more detailed functions. Through multiple deposition operations, color can be realized while additional light control functions can be provided. In the case of the deposition surface, this coating can be applied to the upper surface after transparent coating, and the product can be implemented by using the surface reflection function of the deposition surface. At this time, in order to improve the characteristics of the product, the reflectance can be improved by color coating the space between empty patterns. The cross-sectional view of the double-sided coating film formed through this process is shown in Figure 5.
