Abstract
Description
본 발명은 강화처리된 PET 필름의 하면에 특정 도안(圖案)이 인쇄 코팅된 화면 보호용 PET 필름에 관한 것이다.
The present invention relates to a PET film for screen protection in which a specific pattern is printed on the lower surface of the reinforced PET film.
휴대폰 또는 휴대용 정보단말기 등의 휴대기기 화면(LCD, LED 등)은 긁힘(scratch)을 비롯한 각종 충격과 외부적인 환경에 노출되므로, 이를 보호하기 위한 보호 필름이 상용화되어 있으며, 현재 이러한 보호 필름으로서는 PMMA(polymethylmethacrylate)가 주로 사용되고 있다. PMMA는 가볍고, 내충격성, 가공성 및 화면과의 밀착성이 우수하며, 특히 빛의 투과율이 높고, 높은 표면경도를 가지고 있어 화면 보호용 필름으로 활용하기에 적절하다. Mobile device screens (LCDs, LEDs, etc.) such as mobile phones or portable information terminals are exposed to various impacts such as scratches and external environments, and a protective film for protecting them is commercially available. (polymethylmethacrylate) is mainly used. PMMA is light, impact resistance, processability and adhesion to the screen, especially high light transmittance, high surface hardness is suitable for use as a screen protection film.
한편, 휴대기기의 기능이 다양해지고 고급화 되어 감에 따라 휴대기기를 통해 소유자의 개성을 표현하고자 하는 욕구도 커져 왔으며, 그 결과 휴대기기 외부를 치장하는 휴대기기용 악세서리가 다양하게 출시되고 있다. 또한, 휴대기기 전체를 감싸는 커버도 휴대기기의 기종에 따라 다양하게 출시되고 있다.On the other hand, as the functions of the mobile devices are diversified and advanced, the desire to express the owner's personality through the mobile devices has increased, and as a result, various accessories for mobile devices are provided. In addition, the cover surrounding the entire mobile device is also released in various ways depending on the model of the mobile device.

아래 [참고사진 3]은 스마트폰에 플라스틱 케이스를 씌워 촬영한 사진이다.[Reference Photo 3] below is a picture taken with the plastic case on the smartphone.
[참고사진 3][Reference picture 3]
[참고사진 1]의 경우는 화면(액정) 부분만 노출되어 있으나, [참고사진 2]의 경우는 액정 화면과 함께 화면 위의 면이 노출되어 있고, [참고사진 3]의 경우는 하면의 윗면과 아래면이 모두 노출되어 있다.
In the case of [Reference Photo 1], only the screen (liquid crystal) part is exposed, but in the [Reference Photo 2], the upper surface of the screen is exposed together with the LCD screen, and in the [Reference Photo 3], the upper surface of the lower surface Both bottom and bottom are exposed.
소비자에 따라 [참고사진 2]와 [참고사진 3]에서 보이는 액정 화면 위 또는 아래의 노출면을 그대로 두려고 할 수도 있으나 상기 노출면에도 원하는 색상이나 문양을 넣고자 할 수도 있다. 그러나, 종래의 화면 보호용 필름은 투명하기만 하여 말 그대로 화면을 보호하는 역할만을 하였을 뿐 휴대기기에 새로운 미감(美感)을 부여하는 디자인적 요소로 고려된 바 없었다. 이는 화면 보호용 필름을 디자인 요소로 활용하고자 하는 발상 자체가 없었음은 물론 종래 화면 보호용 필름으로 주로 활용되어 온 PMMA 필름에 도안을 인쇄하기 어렵다는 기술적 문제도 있었던 것으로 보인다.Some consumers may want to leave the exposed surface above or below the LCD screen shown in [Reference Photo 2] and [Reference Photo 3], but may also want to put a desired color or pattern on the exposed surface. However, the screen protection film of the related art has only been transparent and literally only serves to protect the screen, and has not been considered as a design element for imparting new aesthetics to a mobile device. This is because there was no idea to use the screen protection film as a design element itself, as well as the technical problem that it is difficult to print the pattern on the PMMA film mainly used as a conventional screen protection film.
또한 일반 휴대폰에서 스마트폰으로 넘어가면서 액정의 재질은 PC(poly carbonate)에서 강화유리로 바뀌고 화면크기는 점점 커지고 있어, 액정 파손의 위험도 높아지고 있다. 따라서 화면보호 기능뿐만 아니라 액정파손의 방지하는 기능도 추가될 수 있는 필름의 개발이 시급해졌다.
In addition, the liquid crystal material is changed from PC (poly carbonate) to tempered glass, and the screen size is getting bigger and bigger, and the risk of liquid crystal damage is increasing. Therefore, it is urgent to develop a film that can add not only a screen protection function but also a function of preventing liquid crystal damage.
본 발명은 화면 보호용 필름에 도안을 인쇄하여 소비자의 다양한 미적 욕구를 충족시킬 수 있도록 하면서도, 기존의 화면 보호용 기능에 영향을 미치지 않도록 하고, 또한 액정이 충격에서 파손되지 않도록 액정을 강화시키는 화면 보호용 필름을 제공함에 그 목적이 있다.The present invention can print a pattern on the screen protective film to satisfy the various aesthetic needs of the consumer, while not affecting the existing screen protection function, and also a screen protective film for strengthening the liquid crystal so that the liquid crystal is not damaged from impact The purpose is to provide.
본 발명에서는 화면 보호용 필름에 도안을 인쇄하기 위해 PET 필름을 활용한다. PET 필름은 도안을 인쇄하기에 적합하며, 충격강도, 인장강도 및 굴곡강도 등의 기계적 강도가 PMMA 필름보다 우수하다. 그러나 이러한 PET 필름은 표면경도가 낮아 긁힘에 취약하여 유통 또는 사용시의 외부 물질과의 접촉으로 인하여 제품에 손상을 줄 염려가 있는 바, 본 발명에서는 표면경도 향상 및 액정을 충격으로부터 보호하기 위해 강화처리된 PET 필름을 적용한다.
In the present invention, the PET film is used to print the pattern on the screen protective film. PET film is suitable for printing patterns, and mechanical strength such as impact strength, tensile strength and flexural strength is superior to PMMA film. However, the PET film is vulnerable to scratches due to its low surface hardness, which may damage the product due to contact with external materials during distribution or use. Applied PET film.
본 발명이 제공하는 도안이 인쇄된 화면 보호용 PET 필름은 휴대기기에 다양한 미감을 부여하여 고급스럽고 개성있는 외관을 연출해 낼 수 있다.Screen protective PET film printed by the present invention can give a variety of aesthetics to the mobile device can produce a luxurious and individual appearance.
또한 본 발명에 의하면 PET 필름과 강화코팅층 사이에 도안이 인쇄되어 있어 도안의 변색 및 탈색의 위험이 낮다.In addition, according to the present invention is a pattern is printed between the PET film and the reinforcing coating layer is low risk of discoloration and discoloration of the pattern.
특히, 본 발명에 의하면 PET 필름의 인쇄층 하부에 광학용 양면테이프가 점착되어 있어 상기 양면테이프의 일면이 액정에 부착되는 경우 액정이 강화되어 충격에 대한 파손율이 감소되는 효과를 가져온다.
In particular, the optical double-sided tape is adhered to the lower portion of the printing layer of the PET film, so that when one side of the double-sided tape is attached to the liquid crystal, the liquid crystal is strengthened to reduce the breakage rate against impact.

The printed film protection screen provides a PET film comprising a pattern (see FIG. 1).
PET는 열가소성 플라스틱 폴리머의 일종으로서, 가공성(성형성)이 좋고, 내열성, 내충격성 및 광학적 특성(빛 투과율)이 우수하다. 그러나 내스크래치성 및 내마모성이 취약하여 폴리실록세인계 하드 코팅이나 플라즈마 도움증착과 같은 표면 처리 기술을 통하여 내스크래치성을 보완할 필요가 있다.PET is a kind of thermoplastic polymer, which has good processability (formability) and excellent heat resistance, impact resistance and optical properties (light transmittance). However, scratch resistance and abrasion resistance are poor, and thus scratch resistance needs to be compensated for through surface treatment techniques such as polysiloxane-based hard coating or plasma assisted deposition.
현재까지 알려진 PET에 내스크래치성을 부여하는 표면 처리 기술로는 폴리실록세인계 하드 코팅제를 PET 표면에 코팅하는 방법, PET와 내스크래치성이 강한 고분자를 블랜딩하는 방법, 플라즈마를 이용하여 실리콘 다이옥사이드를 화학증착시키는 방법, 및 내스크래치 특성을 보유한 필름을 금형에 삽입하여 사출 성형하는 방법 등이 있다. Surface treatment techniques that impart scratch resistance to PET are known by coating polysiloxane hard coatings on the PET surface, blending PET and polymers with high scratch resistance, and chemically treating silicon dioxide using plasma. The method of depositing, and the method of inserting the film which has a scratch-resistant characteristic into a metal mold | die, and injection molding etc. are mentioned.
