Description
본 발명은 폴더블 스마트폰용 고굴절, 고굴곡 및 저점도 특성 코팅조성물 및 이에 의해 코팅된 코팅층을 포함하는 윈도우부재에 관한 것으로서, 보다 상세하게는 폴더블 스마트폰의 투명 필름상에 고굴절, 고굴곡 및 저점도 특성의 코팅조성물을 코팅하여 굴절율을 향상시켜 휘도 및 시인성을 포함하는 광학특성을 향상시키고 밴딩성 및 굴곡성을 포함하는 유연성을 향상시키며, 저점도를 유지하여 잉크젯 코팅방식으로 코팅을 진행할 수 있는 폴더블 스마트폰용 고굴절, 고굴곡 및 저점도 특성 코팅조성물 및 이에 의해 코팅된 코팅층을 포함하는 윈도우부재에 관한 것이다.The present invention relates to a window member comprising a coating composition with high refractive index, high bending and low viscosity characteristics for a foldable smartphone and a coating layer coated therewith, and more particularly, high refractive index, high bending, and By coating the coating composition with low viscosity properties, the refractive index is improved, optical properties including brightness and visibility are improved, flexibility including bending properties and flexibility are improved, and the coating can be carried out by inkjet coating method by maintaining low viscosity. It relates to a window member comprising a coating composition having high refractive index, high bending and low viscosity characteristics for a foldable smartphone and a coating layer coated therewith.
다양한 정보를 화면으로 구현해 주는 표시장치는 정보 통신 시대의 핵심 기술로 더 얇고 더 가벼우며, 휴대가 가능하면서도 고성능의 방향으로 발전하고 있다. 이에 종래 브라운관의 단점인 무게와 부피를 줄일 수 있는 평판표시장치가 개발되었고, 평판표시장치로는 액정표시장치(LCD, liquid crystal display), 유기발광표시장치(OLED, organic light-emitting display), 전기영동표시장치(EPD, electrophoretic display) 등이 있고, 최근에는 유기발광층의 발광량을 제어하여 영상을 표시하는 유기발광표시장치(OLED, organic light-emitting display)가 각광을 받고 있다. A display device that implements various information on a screen is a key technology in the information and communication era, which is developing in the direction of thinner, lighter, portable and high-performance. Accordingly, a flat panel display device that can reduce the weight and volume, which is a disadvantage of the conventional CRT, has been developed, and as a flat panel display device, a liquid crystal display (LCD), an organic light-emitting display (OLED), There are an electrophoretic display (EPD), and the like, and recently, an organic light-emitting display (OLED) that displays an image by controlling the amount of light emitted by an organic light-emitting layer has been in the spotlight.
액정표시장치(LCD, liquid crystal display) 또는 유기발광표시장치(OLED, organic light-emitting display)가 적용된 스마트폰, 내비게이션, 디지털카메라, 전자책, 휴대용 게임기 또는 각종 단말기와 같은 다양한 모바일 전자기기들이 사용되고 있다. 이러한 모바일 전자기기에 사용되는 통상의 표시장치에는 표시패널의 전방에 사용자가 표시부를 볼 수 있도록 투명하게 구성된 커버 윈도우부재가 구비될 수 있다. 이러한 윈도우부재는 표시장치의 가장 외부에 위치하는 구성이므로 휘도 및 시인성이 우수한 광학적 특성을 가져야 한다. Various mobile electronic devices such as smart phones, navigation devices, digital cameras, e-books, portable game consoles, and various terminals with liquid crystal display (LCD) or organic light-emitting display (OLED) are used. have. A typical display device used in such a mobile electronic device may include a transparent cover window member in front of the display panel so that a user can see the display unit. Since such a window member is a configuration positioned at the outermost part of the display device, it should have excellent optical characteristics in luminance and visibility.
유기발광표시장치(OLED, organic light-emitting diode)는 다수의 화소들이 매트릭스 형태로 배열되어 화상을 표시하게 된다. 여기서, 각 화소는 발광 소자와, 그 발광 소자를 독립적으로 구동하는 다수의 트랜지스터로 이루어진 화소 구동 회로를 구비한다. 이와 같은 유기발광표시소자(OLED, organic light-emitting diode)는 자발광의 유기발광소자를 이용하므로, 별도의 광원을 요구하지 않으며, 초박형 표시장치의 구현이 가능하므로, 근래에는 유기발광표시소자(OLED, organic light-emitting diode)를 이용하고, 발광셀 내부에 터치 전극 어레이를 포함하는 인-셀 터치 구조(In-Cell Touch)의 폴더블 표시장치, 즉 폴더블 스마트폰에 관한 연구가 활발히 이루어지고 있다.In an organic light-emitting diode (OLED), a plurality of pixels are arranged in a matrix to display an image. Here, each pixel includes a pixel driving circuit including a light emitting element and a plurality of transistors independently driving the light emitting element. Since such an organic light-emitting diode (OLED) uses a self-luminous organic light-emitting device, a separate light source is not required, and an ultra-thin display device can be realized. Research on a foldable display device with an in-cell touch structure (OLED, organic light-emitting diode) using an organic light-emitting diode) and including a touch electrode array inside a light emitting cell, that is, a foldable smartphone, has been actively conducted. is losing
이러한 폴더블스마트폰은 표시패널을 포함한 스마트폰 자체가 폴딩되는 구조를 가지며, 따라서 폴딩이 가능한 커버 윈도우부재가 사용된다. 이와 같이 폴딩이 가능한 커버 윈도우부재를 형성하기 위하여, 종래의 강화글라스로 된 유리기판 대신에 고굴곡성을 가지는 CPI(coloreless polyimide) 필름을 이용하여 윈도우부재를 제작하는 것이 타당하다. 다만 이같은 CPI(coloreless polyimide) 필름을 이용한 커버 윈도우부재는 굴절율이 낮아 휘도 및 시인성이 떨어지고 광학적 특성이 미흡한 문제가 있다. Such a foldable smartphone has a structure in which the smartphone itself including the display panel is folded, and thus a cover window member that can be folded is used. In order to form a foldable cover window member as described above, it is reasonable to use a colorless polyimide (CPI) film having high flexibility instead of a conventional glass substrate made of tempered glass to fabricate the window member. However, the cover window member using such a colorless polyimide (CPI) film has a low refractive index, so luminance and visibility are poor, and optical properties are insufficient.
즉, 폴더블 스마트폰의 커버 윈도우부재에 고굴곡성을 가지는 CPI(coloreless polyimide) 필름이 많이 사용되고 있는데, 고굴곡성을 가지는 CPI(coloreless polyimide) 필름은 굴절율이 낮아 휘도 및 시인성이 떨어지고 광학적 특성이 미흡한 문제점을 가지고 있으므로, 고굴곡 특성은 유지하면서 투명 필름의 굴절율을 높여 우수한 광학적 특성을 가질 수 있도록 투명 필름의 표면에 코팅되는 폴더블 스마트폰용 고굴절 및 고굴곡 특성 코팅조성물의 필요성이 커지고 있다. 나아가, 폴더블 스마트폰용 고굴절 및 고굴곡 특성 코팅조성물의 점도가 높으면 코팅 공정의 진행에 문제가 발생할 수 있고, 특히, 잉크젯 코팅방식을 이용할 수 없는 문제가 존재한다. 따라서, 고굴절 특성과 고굴곡 특성은 유지하면서 낮은 점도를 가질 수 있는 폴더블 스마트폰용 고굴절, 고굴곡 및 저점도 특성 코팅조성물의 필요성이 커지고 있다.In other words, a colorless polyimide (CPI) film having high flexibility is widely used for the cover window member of a foldable smartphone. However, the colorless polyimide (CPI) film having high flexibility has a low refractive index, so luminance and visibility are low, and the optical characteristics are insufficient. Therefore, the need for a coating composition with high refractive index and high bending properties for foldable smartphones coated on the surface of the transparent film to have excellent optical properties by increasing the refractive index of the transparent film while maintaining high bending properties is increasing. Furthermore, if the viscosity of the high refractive index and high bending property coating composition for a foldable smartphone is high, a problem may occur in the progress of the coating process, and in particular, there is a problem that the inkjet coating method cannot be used. Accordingly, there is a growing need for a coating composition with high refractive, high bending and low viscosity properties for foldable smartphones that can have low viscosity while maintaining high refractive and high bending properties.
즉, 폴더블 스마트폰의 커버 윈도우부재에 적용되는 가장 중요한 물성은 광학적 특성과 고굴곡 특성인데 종래의 폴더블 스마트폰의 커버 윈도우부재는 광학적 특성 또는 고굴곡 특성 중 어느 하나만을 만족하는 것이 일반적이다. 이에 본 발명의 발명자는 폴더블 스마트폰용 고굴절, 고굴곡 및 저점도 특성 코팅조성물을 개발하여 고굴절 특성을 가지면서 고굴곡 특성을 유지하여, 우수한 광학적 특성 및 고굴곡 특성을 가질 수 있도록 하였고, 저점도 특성을 가져 잉크젯 코팅방식을 사용할 수 있도록 하였다. That is, the most important physical properties applied to the cover window member of a foldable smartphone are optical properties and high bending properties. It is common that the cover window member of the conventional foldable smartphone satisfies either one of optical properties or high bending properties. . Accordingly, the inventor of the present invention developed a coating composition with high refractive, high bending and low viscosity properties for a foldable smartphone, maintaining high bending properties while having high refractive properties, so that it has excellent optical properties and high bending properties, and low viscosity It has properties so that the inkjet coating method can be used.
대한민국 공개특허공보 10-2016-0106889호의 디스플레이용 투명 필름 및 그 제조방법에서는 무기물 배리어층을 사전에 안티 블로킹 처리된 투명 PET 필름 부착에 의한 구성으로 보호될 수 있게 한 것에 의해, 무기물 배리어층에 손상(Damage)을 안 주면서도, 블로킹 방지와 아울러 외부로부터의 긁힘을 방지하는 내긁힘 특성을 발휘하게 하고, 또 내긁힘 특성에 의한 보호지 추가 설치작업의 불필요로 인한 제조 원가의 절감을 달성되게 하며, 또한 접착제에 의한 투명 PET 필름의 무기물 배리어층에 대한 부착은 접착제가 열 안정성을 부여하는 역할을 하여 내열성을 갖게 함은 물론 필름 움 현상을 없게 하는 이점을 부여하고, 또한 가운데 접착제를 중심으로 하여 양측에 투명 PET 필름의 설치로 PET 필름 위에 기존과 같이 유기막층이 설치된 구조에 비하여 컬(Curl)발생을 적게 할 수 있게 하는 디스플레이용 투명 플라스틱 필름을 개시하고 있다. 그러나 상기 디스플레이용 투명 플라스틱 필름은 투명 PET 필름에 관한 것으로 폴더블 스마트폰에 주로 사용되는 CPI(coloreless polyimide) 필름에 직접 적용할 수 없는 문제가 있다. 또한 이와 같은 종래의 기술에서는 CPI(coloreless polyimide) 필름의 고굴곡성을 유지하면서 고굴절 특성과 저점도 특성을 모두 구현하려는 시도 자체가 거의 없는 실정이다.In the transparent film for display of Korean Patent Laid-Open Publication No. 10-2016-0106889 and its manufacturing method, the inorganic barrier layer can be protected by attaching an anti-blocking treatment to the transparent PET film in advance, thereby damaging the inorganic barrier layer. While not giving (damage), it prevents blocking and exhibits scratch-resistance to prevent scratching from the outside, and achieves reduction in manufacturing cost due to the need for additional installation work of protective paper due to scratch-resistance characteristics, and The adhesion of the transparent PET film to the inorganic barrier layer by the adhesive gives the adhesive the advantage of not only having heat resistance as well as preventing film shrinkage by providing thermal stability, but also Disclosed is a transparent plastic film for display that can reduce curl generation by installing a transparent PET film compared to a structure in which an organic film layer is installed on the PET film as in the past. However, the transparent plastic film for display relates to a transparent PET film, and there is a problem in that it cannot be directly applied to a colorless polyimide (CPI) film mainly used in foldable smartphones. In addition, in the prior art as described above, there are few attempts to realize both high refractive index and low viscosity characteristics while maintaining the high flexibility of a colorless polyimide (CPI) film.

본 발명인 폴더블 스마트폰용 고굴절, 고굴곡 및 저점도 특성 코팅조성물은 고굴절 특성 물질로 지르코니아 아크릴 모노머 졸과 플루오렌계 디아크릴레이트를 포함하며, 고굴곡 특성 물질로 Urethane-acrylic ester co-polymer를 포함하며, 저점도 특성 물질로 아크릴레이트 모노머를 포함하여 구성된다. 고굴절 특성을 가지는 지르코니아 아크릴 모노머 졸과 플루오렌계 디아크릴레이트가 코팅조성물에 포함됨으로써, 폴더블 스마트폰의 투명 필름 상부 표면에 코팅조성물을 코팅하고 경화시켜 코팅층을 형성하였을때 고굴절 특성을 가지게 된다. 그러나, 고굴절 특성을 가지는 지르코니아 아크릴 모노머 졸과 플루오렌계 디아크릴레이트가 코팅조성물에 포함됨으로써, 코팅조성물을 코팅하고 경화시켜 코팅층을 형성하였을때 굴곡 특성이 저하되는 문제가 발생할 수 있고, 코팅조성물의 점도가 상승하여 잉크젯 방식으로 코팅을 진행하기 어려운 문제가 발생할 수 있다. 이러한 굴곡 특성 저하의 문제를 해결하기 위해 코팅조성물에 고굴곡 특성 물질로 Urethane-acrylic ester co-polymer를 포함시켰으며, 점도 상승의 문제를 해결하기 위해 코팅조성물에 저점도 특성 물질로 아크릴레이트 모노머를 포함시켰다. 본 발명인 코팅조성물에서 고굴절 특성 물질인 지르코니아 아크릴 모노머 졸과 플루오렌계 디아크릴레이트, 고굴곡 특성 물질인 Urethane-acrylic ester co-polymer, 저점도 특성 물질인 아크릴레이트 모노머는 서로 혼화성을 지니며, 서로의 특성에 주는 영향을 최소화하는 독립적인 구성에 해당한다.The present invention's high refractive index, high bending and low viscosity coating composition for foldable smartphones includes zirconia acrylic monomer sol and fluorene-based diacrylate as a high refractive material, and contains urethane-acrylic ester co-polymer as a high-flexibility material and is composed of an acrylate monomer as a low-viscosity material. Since the zirconia acrylic monomer sol and fluorene-based diacrylate having high refractive properties are included in the coating composition, the coating composition is coated on the upper surface of the transparent film of the foldable smartphone and cured to form a coating layer. It has high refractive properties. However, since the zirconia acryl monomer sol and fluorene-based diacrylate having high refractive properties are included in the coating composition, when the coating composition is coated and cured to form a coating layer, there may be a problem that the flexural properties are lowered, and the coating composition As the viscosity increases, it may be difficult to proceed with the coating by the inkjet method. In order to solve the problem of this decrease in flexural properties, urethane-acrylic ester co-polymer was included in the coating composition as a high-flexibility material. To solve the problem of viscosity increase, acrylate monomer was added as a low-viscosity material to the coating composition. included In the coating composition of the present invention, zirconia acrylic monomer sol and fluorene-based diacrylate, a high refractive material, urethane-acrylic ester co-polymer, and an acrylate monomer, a low-viscosity material, are miscible with each other in the coating composition of the present invention, It corresponds to an independent composition that minimizes the influence on each other's characteristics.

However, the curing method can be freely selected according to the situation, and the high refractive index, high bending and low viscosity coating composition for the foldable smartphone according to the present invention is not necessarily limited to the photocuring method. The leveling agent strongly lowers the surface tension of the high refractive index, high bending, and low viscosity characteristic coating layer. By strongly lowering the surface tension of the coating layer, the wettability of the material is improved and cratering can be prevented. However, if the leveling agent is excessive, compatibility with other raw materials is insufficient due to the non-polar nature of the leveling agent. and stains may occur on the surface at high temperature and high humidity.

In the case of cracking, breaking, or wrinkling in the film specimen after folding measurement for 200,000 times, it was evaluated as NG, and if cracks, breaking, or wrinkling did not appear, it was evaluated as OK.
(4) 투과율 및 Haze 측정(4) Measurement of transmittance and haze
광투과율 평가는 ASTM D1003 기준으로 전광선투과율(Tt)과 평행투과율(Tp)을 측정하고, 전광선투과율(Tt)에서 평행투과율(Tp)을 뺀 값이 확산투과율(Td)에 해당한다. 전광선투과율(Tt)이 크고 확산투과율(Td)이 작을 수록 광학적 성질이 우수한 물질에 해당한다. 또한 빛이 투명한 재료 안을 통과할 때 재료의 종류에 따라서는 반사나 흡수 외에 그 재료의 고유 성질에 따라 광선이 확산되어 불투명한 흐림상 외관을 나타내는 것이 존재하는데, 이 현상을 헤이즈(Haze)라고 부르며, 이같이 투명한 것에 입사한 광선이 확산하는 정도를 헤이즈라 한다. 헤이즈가 작을 수록 광학적 성질이 우수한 물질에 해당한다.For evaluation of light transmittance, total light transmittance (Tt) and parallel transmittance (Tp) are measured based on ASTM D1003, and the value obtained by subtracting the parallel transmittance (Tp) from the total light transmittance (Tt) corresponds to the diffuse transmittance (Td). The higher the total light transmittance (Tt) and the smaller the diffuse transmittance (Td), the better the optical properties. In addition, when light passes through a transparent material, depending on the type of material, in addition to reflection or absorption, light is diffused according to the intrinsic property of the material to show an opaque, cloudy appearance. This phenomenon is called haze. , the degree of diffusion of light incident on a transparent object is called haze. The smaller the haze, the better the optical properties are.
헤이즈(Haze) = 확산투과율(Td) / 전광선투과율(Tt)Haze = diffuse transmittance (Td) / total light transmittance (Tt)
