본 고안은 정보화시대의 도래에 따라 개인 휴대품으로 되어 버린 핸드폰에 관한 것으로서, 좀더 구체적으로는 다양한 내용이 디스플레이(display)되는 화면을 안정적으로 보호하기 위한 핸드폰의 화면구조에 관한 것이다.The present invention relates to a mobile phone that has become a personal portable device with the advent of the information age, and more particularly, to a screen structure of a mobile phone for stably protecting a screen on which various contents are displayed.

정보화산업(IT)의 발달로 인해 핸드폰의 보급이 급증하여 거의 모든 국민이 핸드폰을 휴대하고 있는 실정이다.Due to the development of information technology (IT), the spread of mobile phones has rapidly increased and almost all people are carrying mobile phones.

도 1은 일반적인 핸드폰의 구조를 나타낸 정면도로서, 본체(1)에 슬라이딩 가능하게 결합된 커버(2)에 다양한 내용이 디스플레이되는 화면(3)이 표현되어 있고 본체(1)에는 다이얼링을 위한 다수 개의 버튼(4)이, 그리고 커버(2)에는 다양한 기능을 선택하기 위한 조작버튼(5)이 구비되어 있다.1 is a front view showing a structure of a general mobile phone, a screen 3 on which various contents are displayed on a cover 2 slidably coupled to the main body 1 is represented, and the main body 1 has a plurality of dials for dialing. The button 4 and the cover 2 are provided with operation buttons 5 for selecting various functions.

상기한 구조를 갖는 핸드폰은 화면(3)을 통해 다양한 기능을 사용자에게 제공하므로 화면의 재질을 투명한 합성수지(PMMA : Polymethylmethacrylate)로 사용하고 있다.Since the mobile phone having the above structure provides various functions to the user through the screen 3, the material of the screen is used as a transparent synthetic resin (PMMA: Polymethylmethacrylate).

그러나 화면(3)을 투명재질의 합성수지로 제작한 경우에는 화면(3)을 사출 성형하는 과정에서 두께가 얇아 수축 등에 의해 변형되거나, 핸드폰의 사용 시 LCD모듈(도시는 생략함)에서 발생하는 고온의 열에 의해 변형될 우려가 있어 두께를 두껍게 설계하여야 하므로 두께가 얇은 핸드폰을 선호하는 소비자의 욕구를 충족시키는데 한계가 있다.However, when the screen 3 is made of a synthetic resin of transparent material, the screen 3 is thin in the process of injection molding and is deformed by shrinkage, or a high temperature generated by an LCD module (not shown) when using a mobile phone. Because of the possibility of deformation due to the heat of thick design should be thick, there is a limit to satisfy the needs of consumers who prefer a thin cell phone.

더욱이, LCD모듈의 구동에 따라 발생하는 열에 의해 합성수지재질의 화면(3)이 변형되지 않도록 LCD모듈과 화면(3)의 간격을 0.7-1.0mm정도 이격시켜야 하므로 핸드폰의 두께를 줄이는데 더욱 한계가 있다.Moreover, the distance between the LCD module and the screen 3 should be separated by about 0.7-1.0 mm so that the screen 3 of the synthetic resin material is not deformed by the heat generated by the operation of the LCD module. .

또한, 화면(3)이 합성수지로 이루어져 있어 강도가 약하여 핸드폰을 장기간 사용 시 화면의 표면에 긁힘현상이 발생되어 화면에 나타나는 내용을 신속하게 식별하는데 많은 불편함을 느끼게 하였음은 물론 화면에 과대한 충격이 가해질 경우 에는 화면이 깨지는 치명적인 결함을 나타내었다.In addition, since the screen 3 is made of synthetic resin, the strength is low so that scratches occur on the surface of the screen when the phone is used for a long time, which makes the user feel a lot of inconvenience in identifying the contents on the screen quickly. When this is done, the screen shows a fatal flaw.

따라서 상기한 플라스틱 재질의 화면이 갖는 문제점을 감안하여 석영재질의 화면을 적용할 경우에는 경도가 커 표면에 긁힘현상이 줄어드는 잇점은 있으나, 소재인 석영의 가공성이 떨어져 생산성의 저하를 초래하게 되었음은 물론 가공에 따른 불량률이 커 생산원가가 상승되었음은 물론 충격으로 인해 석영재질의 화면이 깨질 경우에는 비산되어 부상을 입는 경우가 발생되었다.Therefore, in view of the problems of the plastic screen, the application of the quartz screen has the advantage of reducing the scratches on the surface due to the large hardness, but the workability of the quartz material is lowered, leading to a decrease in productivity Of course, due to the high defect rate due to processing, the production cost was increased, and when the screen of quartz material was broken due to impact, it was scattered and injured.

본 고안은 이와 같은 종래의 문제점을 해결하기 위해 안출한 것으로서, 화면을 구성하는 재질로 충격 및 열에 강한 강화유리를 사용하면서도 충격에 의해 강화유리가 깨지더라도 비산되지 않도록 하는데 그 목적이 있다.The present invention has been made in order to solve such a conventional problem, the object of the screen is to use a tempered glass resistant to impact and heat while the tempered glass is not scattered even if the impact is broken.

상기 목적을 달성하기 위한 본 고안의 형태에 따르면, 본체 또는 커버에 투명재질의 화면이 고정된 핸드폰에 있어서, 상기 화면이 투명재질의 강화유리와, 상기 강화유리의 이면에 접착 고정되는 투명재질의 PET필름과, 상기 강화유리에 PET필름이 접착 고정되도록 강화유리의 이면에 도포된 점착층으로 구성된 것을 특징으로 하는 핸드폰의 화면구조가 제공된다.According to a form of the present invention for achieving the above object, in the mobile phone is fixed to the screen of the transparent material on the main body or cover, the screen of the transparent material and the transparent material that is adhesively fixed to the back of the tempered glass There is provided a screen structure of a mobile phone, characterized in that consisting of a PET film, and an adhesive layer applied to the back surface of the tempered glass so that the PET film is fixed to the tempered glass.

이하, 본 고안을 일 실시예로 도시한 도 2 및 도 3을 참고하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to FIGS. 2 and 3 as an embodiment.

도 2는 본 고안의 화면을 나타낸 사시도이고 도 3은 본 고안의 강화유리에 PET필름을 접착하는 상태도로서, 본 고안은 본체(1)의 디스플레이부에 고정되는 화면이 담금질과 표면처리 등의 방법으로 강도를 증대시킨 0.5-1.0mm 두께의 강화유리(tempered grass)(11)로 되어 있고 상기 강화유리의 배면에는 인장강도, 기계적 강도, 경도가 높으며 내 마찰성 및 사용온도(-40℃-100℃정도)의 범위가 넓은 PET필름(12)이 점착층(13)에 의해 접착 고정되어 있다.Figure 2 is a perspective view showing a screen of the present invention and Figure 3 is a state diagram for bonding the PET film to the tempered glass of the present invention, the present invention is a screen fixed to the display unit of the main body (1) method such as quenching and surface treatment It is made of 0.5-1.0mm thick tempered glass (11) with increased strength, and the back of the tempered glass has high tensile strength, mechanical strength, hardness, friction resistance and service temperature (-40 ℃ -100 ℃). The PET film 12 with a wide range of degrees) is adhesively fixed by the adhesive layer 13.

이 때, 상기 PET필름(12)의 두께는 40-60㎛ 정도가 바람직한데, 그 두께가 40㎛ 보다 얇으면 충격에 의해 강화유리(11)가 깨질 때 PET필름(12)이 찢어져 강화유리(11)가 비산될 우려가 있고, 60㎛ 보다 두꺼우면 생산원가가 상승되는 결과를 초래하게 된다.At this time, the thickness of the PET film 12 is preferably about 40-60㎛, if the thickness is thinner than 40㎛ PET film 12 is torn when the tempered glass 11 is broken by impact (reinforced glass ( 11) is likely to scatter, and if it is thicker than 60㎛, it will result in an increase in production cost.

또한, 점착층(13)의 도포두께는 9-11㎛가 바람직한데, 그 두께가 9㎛ 이하이면 LCD모듈의 구동에 따라 발생된 열에 의해 PET필름(12)이 강화유리(11)로부터 박리될 우려가 있고, 11㎛ 보다 두꺼우면 점착층(13)을 건조시키는데 소요되는 시간이 지연되므로 생산성의 저하를 초래하게 된다.In addition, the coating thickness of the adhesive layer 13 is preferably 9-11 μm. If the thickness is 9 μm or less, the PET film 12 may be peeled from the tempered glass 11 by heat generated by driving the LCD module. There is a concern that if the thickness is larger than 11 µm, the time required for drying the adhesive layer 13 is delayed, resulting in a decrease in productivity.

따라서 소정의 크기로 생산된 강화유리(11)를 이송시키는 과정에서 점착제(14)가 담겨진 탱크(15)에서 구동로울러(16)가 회전하면 상기 구동로울러에 뭍은 점착제가 도포로울러(17)의 표면에 뭍게 되고, 이에 따라 강화유리(11)의 표면에 소정의 두께(9-11㎛)로 점착제(14)가 도포된다.Therefore, when the driving roller 16 is rotated in the tank 15 in which the pressure-sensitive adhesive 14 is contained in the process of transporting the tempered glass 11 produced to a predetermined size, the pressure-sensitive adhesive accumulated on the driving roller is applied to the application roller 17. It sticks to the surface, and the adhesive 14 is apply | coated to the surface of the tempered glass 11 by predetermined thickness (9-11 micrometers).

이러한 상태에서 권취롤(18)에 감겨진 PET필름(12)을 점착제(14)가 도포된 강화유리(11) 측으로 공급하면서 전용설비의 로울러(도시는 생략함)에 의해 PET필 름에 압력을 가하면 상기 강화유리(11)의 표면(배면)에 PET필름(12)이 부착되는 것이다.In this state, the PET film 12 wound on the take-up roll 18 is supplied to the tempered glass 11 side to which the pressure-sensitive adhesive 14 is applied, and pressure is applied to the PET film by a roller (not shown) of a dedicated facility. When applied, the PET film 12 is attached to the surface (back) of the tempered glass 11.

이상에서 설명한 바와 같이 본 고안은 강도 및 경도가 큰 강화유리(11)의 배면에 기계적 특성 및 물리적 특성이 양호한 PET필름(12)이 점착제(13)에 의해 견고히 부착되어 있어 핸드폰을 장기간 사용하더라도 화면이 긁히는 현상을 미연에 방지하게 됨은 물론 부주의로 충격이 가해져 강화유리(11)가 깨지더라도 배면에 PET필름(12)이 부착되어 있어 비산되지 않으므로 비산에 의한 부상을 예방하게 되는 효과를 얻게 된다.As described above, according to the present invention, the PET film 12 having good mechanical and physical properties is firmly attached to the back of the tempered glass 11 having high strength and hardness by the adhesive 13 so that the screen can be used for a long time. This scratching phenomenon is not only prevented in advance, of course, even if the impact is inadvertently applied, even if the tempered glass 11 is broken PET film 12 is attached to the back is not scattered, thereby preventing the injury caused by scattering.
