Description
본 고안은 휴대 전화용 전자파 차폐 투명창에 관한 것으로, 특히 휴대 전화기에 있어 각종 정보가 표시되는 액정 화면을 보호하기 위해 장착되는 휴대 전화용 투명창에 전자파 차폐층을 형성하여 휴대 전화기 내에서 발생되는 유해 전자파가 외부로 누설됨을 차폐시키기 위한 휴대 전화용 전자파 차폐 투명창에 관한 것이다.The present invention relates to an electromagnetic wave shielding transparent window for a mobile phone, and in particular, an electromagnetic wave shielding layer is formed in a transparent window for a mobile phone mounted to protect a liquid crystal screen on which various information is displayed. The present invention relates to an electromagnetic shielding transparent window for a mobile phone for shielding harmful electromagnetic waves from leaking to the outside.
일반적으로 휴대 전화기는 기기내부에 각종 전자파가 발생되는데, 이러한 전자파는 기기 내부의 각 동작부위에 영향을 미쳐 오동작을 유발시키거나 사용자의 인체에 좋지 않은 영향을 주게된다.In general, various types of electromagnetic waves are generated in a mobile phone, and these electromagnetic waves affect each operating part inside the device, causing malfunctions or adversely affecting the user's human body.
도 1은 종래의 경우 전자파 차폐를 위해 지그를 사용하여 지그와 휴대폰 외장케이스의 결합을 보여주는 사시도이다.1 is a perspective view showing a combination of a jig and a mobile phone exterior case using a jig for shielding the electromagnetic waves in the conventional case.
도 1에 도시된 바와 같이 상부지그(1)와 하부지그(2)를 구비하여 하부지그(2) 내에 휴대폰의 외장케이스(3)를 안착시키고, 휴대폰의 외장케이스(3)의 상측으로 안착된 외장케이스(3)를 덮어 전자파 차폐층이 형성되어야 할 부분만을 외측으로 드러날 수 있도록 상부지그(1)에 공간을 형성하여 전자파 차폐를 위한 전도성 도료를 지그쪽으로 분사시키거나 진공증착에 의해 휴대폰의 외장케이스(3)의 특정 부위에 전자파 차폐층을 형성시킨다.As shown in FIG. 1, the upper jig 1 and the lower jig 2 are provided to seat the outer case 3 of the mobile phone in the lower jig 2, and seated toward the upper side of the outer case 3 of the mobile phone. Cover the outer case 3 to form a space in the upper jig 1 so that only the part where the electromagnetic wave shielding layer should be formed is exposed to the outside, and spray the conductive paint for shielding the electromagnetic wave to the jig, or the exterior of the mobile phone by vacuum deposition. An electromagnetic wave shielding layer is formed on a specific portion of the case 3.
종래의 경우 분사에 의해 전자파 차폐층을 형성하는 경우 불필요하게 많은 양의 전도성 도료가 소모될 수 있으며, 분사식 및 진공증착에 의한 경우 모두 일일이 지그를 사용하여야 하는 문제점을 가지고 있다.In the conventional case, when the electromagnetic shielding layer is formed by spraying, an unnecessarily large amount of conductive paint may be consumed. In the case of spraying and vacuum deposition, there is a problem that jig should be used one by one.
본 고안의 목적은 각종 정보가 표시되는 액정 화면을 보호하기 위해 장착되는 휴대 전화용 투명창에 실크스크린 인쇄에 의해 전자파 차폐층을 형성하므로써 지그를 사용할 필요가 없는 휴대 전화용 전자파 차폐 투명창을 제공하는 데 있다.An object of the present invention is to provide an electromagnetic shielding transparent window for a mobile phone which does not need to use a jig by forming an electromagnetic shielding layer by silk screen printing on a transparent window for a mobile phone mounted to protect a liquid crystal screen on which various information is displayed. There is.

상기의 목적을 달성하기 위하여 본 고안의 휴대 전화용 전자파 차폐 투명창은 각종 정보가 표시되는 휴대전화기의 액정화면표시부를 보호하며 투시가능한 투명 합성수지재 시트와, 상기 투명 합성수지재 시트의 가장자리에 금속제가 증착형성된 금속증착층과, 상기 금속증착층의 표면에 실크스크린 인쇄로 코팅된 전자파 차폐층이 형성된 것을 특징으로 한다.In order to achieve the above object, the electromagnetic wave shielding transparent window for a mobile phone of the present invention protects the liquid crystal display part of a mobile phone on which various information is displayed and is transparent to the transparent synthetic resin sheet, and a metal is formed at the edge of the transparent synthetic resin sheet. The deposition-deposited metal deposition layer, and the electromagnetic shielding layer is coated on the surface of the metal deposition layer by silkscreen printing is formed.
이하, 첨부된 도면을 참조하여 본 고안의 휴대 전화용 전자파 차폐 투명창을 상세히 설명하고자 한다.Hereinafter, an electromagnetic wave shielding transparent window for a mobile phone of the present invention will be described in detail with reference to the accompanying drawings.
도 3a 내지 도 3d에 도시된 바와 같이 본 고안의 휴대 전화용 전자파 차폐 투명창은 각종 정보가 표시되는 휴대전화기(200)의 액정화면표시부(30)를 보호하며 투시가능한 투명 합성수지재 시트(10)와, 투명 합성수지재 시트(10)의 가장자리에 금속제가 증착형성된 금속증착층(20)과, 금속증착층(20)의 표면에 실크스크린 인쇄로 코팅된 전자파 차폐층(40)이 형성된다.As shown in FIGS. 3A to 3D, the electromagnetic wave shielding transparent window for a mobile phone of the present invention protects the liquid crystal display unit 30 of the mobile phone 200 in which various kinds of information are displayed and is transparent to view the transparent synthetic resin sheet 10. And a metal deposition layer 20 on which metal is deposited on the edge of the transparent synthetic resin sheet 10, and an electromagnetic shielding layer 40 coated by silkscreen printing on the surface of the metal deposition layer 20.
상기의 구성에 따른 본 고안인 휴대 전화용 전자파 차폐 투명창의 동작은 다음과 같다.Operation of the electromagnetic wave shielding transparent window for a mobile phone according to the above configuration is as follows.
도 2는 일반적인 휴대 전화기를 도시한 사시도이다.2 is a perspective view showing a typical mobile phone.
도 2에 도시된 바와 같이 일반적으로 휴대 전화기(200)는 사용자의 편익을 위해 다양한 형태와 기능을 가지게 되며, 그 가운데 휴대 전화기(200)의 전반적인 정보를 사용가제 표시하는 액정 화면이 중앙부에 위치하며, 이러한 액정 화면은 휴대 전화기의 송,수신 상태 등과 같이 운용에 요구되는 각종 정보를 표시하는 것으로서, 액정 화면은 외부 충격에 극히 취약하므로 이를 보호하기 위해 액정 화면 외측에 합성수지로 제작된 투명창(100)이 장착된다.As shown in FIG. 2, the mobile phone 200 generally has various forms and functions for the convenience of the user. Among them, a liquid crystal screen displaying general information of the mobile phone 200 is located in the center. In addition, the liquid crystal screen displays various information required for operation such as a transmission and reception state of a mobile phone, and since the liquid crystal screen is extremely vulnerable to external impact, a transparent window 100 made of a synthetic resin outside the liquid crystal screen to protect it. ) Is mounted.
도 3a 내지 도3d는 본 고안의 휴대 전화용 전자파 차폐 투명창의 제조공정도, 도 4a 및 도 4b는 본 고안의 휴대 전화용 전자파 차폐 투명창의 평면도 및 단면도이다.3A to 3D are manufacturing process diagrams of the electromagnetic wave shielding transparent window for mobile phones of the present invention, and FIGS. 4A and 4B are plan views and cross-sectional views of the electromagnetic shielding transparent window for mobile phones of the present invention.
도 3a 내지 도3d, 도 4a 및 도 4b에 도시된 바와 같이 본 고안의 휴대 전화용 전자파 차폐 투명창은 소정의 두께와 표면적을 가지는 아크릴, PC 또는 PET 등의 재질로 이루어진 투명 합성수지재 시트(10) 전면에 미러효과를 주기 위하여 알루미늄, 구리, 티타늄 등의 금속제를 스퍼터링(sputtering) 증착에 의해 일정한 두께의 금속증착층(20)을 형성한다. 금속증착층(20)이 증착된 투명 합성수지재 시트(10)는 금속증착층(20)에 의해 휴대전화기(200)의 액정화면표시부(30)는 불투명하게 되므로 액정 화면 표시가 가능한 투명창(100)을 형성하기 위해 약품을 사용하여 투명창(100) 중 액정화면표시부(30)의 금속증착층(20) 만을 제거한다.As shown in FIGS. 3A to 3D, 4A, and 4B, the electromagnetic wave shielding transparent window for a mobile phone of the present invention is a transparent synthetic resin sheet 10 made of a material such as acrylic, PC, or PET having a predetermined thickness and surface area. In order to give a mirror effect to the entire surface, a metal deposition layer 20 having a predetermined thickness is formed by sputtering deposition of metal such as aluminum, copper, or titanium. The transparent synthetic resin material sheet 10 on which the metal deposition layer 20 is deposited is opaque by the liquid crystal display unit 30 of the mobile phone 200 by the metal deposition layer 20. Remove the metal deposition layer 20 of the liquid crystal display (30) of the transparent window 100 using a chemical to form a).
투명창(100) 중 액정화면표시부(30)의 금속증착층(20) 만을 제거한 후 남아 있는 금속증착층(20) 상부에만 실크스크린 인쇄방법에 의해 도전성 재료인 전자파 차폐층(40)을 형성한다.After removing only the metal deposition layer 20 of the LCD screen 30 of the transparent window 100, the electromagnetic shielding layer 40, which is a conductive material, is formed on the upper portion of the remaining metal deposition layer 20 by a silkscreen printing method. .
따라서 액정화면표시부(30)를 제외한 금속증착층(20) 상부에만 전자파 차폐층(40)을 형성하므로써, 종래와는 달리 지그가 필요 없으므로 손쉽게 전자파 차폐층(40)을 형성할 수 있다.Therefore, since the electromagnetic shielding layer 40 is formed only on the metal deposition layer 20 except for the liquid crystal display 30, since the jig is not required, the electromagnetic shielding layer 40 can be easily formed.
본 고안의 휴대 전화용 전자파 차폐 투명창은 액정화면표시부를 제외한 금속증착층 상부에만 전자파 차폐층을 형성하므로써, 종래와는 달리 지그가 필요 없으므로 손쉽게 전자파 차폐층을 형성할 수 있다.The electromagnetic wave shielding transparent window for a mobile phone of the present invention forms an electromagnetic wave shielding layer only on the upper portion of the metal deposition layer except for the liquid crystal display, and thus, unlike the related art, it is possible to easily form the electromagnetic shielding layer.
