Description

엘시디 모듈LCD module

본 발명은 엘시디 모듈에 관한 것으로, 더욱 상세하게는 몰드 프레임의 하부면에 완충부를 형성하여 외부에서 전해지는 충격을 흡수할 수 있도록 한 엘시디 모듈에 관한 것이다.The present invention relates to an LCD module, and more particularly, to an LCD module that can absorb a shock transmitted from the outside by forming a buffer portion on the lower surface of the mold frame.

일반적으로 현대사회가 정보 사회화되어감에 따라 정보표시장치의 하나인 LCD 장치, 예를 들어, 노트 피시(note pc)의 중요성이 점차 증가되고 있다. 지금까지 가장 널리 사용되고 있는 CRT(cathode ray tube)는 성능이나 가격적인 측면에서 많은 장점을 갖고 있지만 소형화 또는 휴대성 측면에서 많은 단점을 갖고 있다. 반면에 LCD 장치는 가격측면에서 다소 비싸지만 소형화, 경량화, 박형화 및 저전력소비화 등의 장점을 갖고 있어 CRT의 단점을 극복할 수 있는 대체수단으로 주목되고 있다.In general, as the modern society becomes information socialized, the importance of LCD devices, for example, note pcs, which is one of information display devices, is gradually increasing. Cathode ray tube (CRT), which is widely used so far, has many advantages in terms of performance and cost, but has many disadvantages in terms of miniaturization or portability. On the other hand, although LCD devices are somewhat expensive in terms of price, they are attracting attention as an alternative means of overcoming the shortcomings of CRTs because they have advantages such as miniaturization, light weight, thinness and low power consumption.

이러한 LCD 장치는 크게 데이터를 입력하는 키보드를 구비한 본체부와 본체부에 힌지결합되어 접철되고 데이터를 디스플레이하는 표시부로 이루어진다.The LCD device includes a main body having a keyboard for inputting data and a display unit for hinge folding and displaying data.

표시부는 크게 데이터를 디스플레이하는 LCD 모듈과 디스플레이 영역을 제외한 LCD 모듈의 외부를 감싸는 케이스로 이루어진다.The display unit is largely comprised of an LCD module displaying data and a case surrounding the outside of the LCD module except the display area.

LCD 모듈은 소정의 수납공간을 갖는 몰드 프레임과 몰드 프레임의 수납공간에 수용되는 도광판과 도광판의 상부에 놓여지는 시트류들과 시트류들 상부에 놓여지는 LCD 패널과 도광판의 측면에 설치되는 램프 어셈블리와 LCD 패널의 상부에 위치하여 LCD 패널의 가장자리 및 몰드 프레임의 측면을 커버하는 탑샷시 등으로 이루어진다.The LCD module includes a mold frame having a predetermined storage space, a light guide plate accommodated in the storage space of the mold frame, sheets placed on the light guide plate, and an LCD panel placed on the sheets, and a lamp assembly installed on the side of the light guide plate. And a top shot cover positioned at the top of the LCD panel to cover the edge of the LCD panel and the side of the mold frame.

이러한 구성 요소들을 갖는 LCD 모듈은 조립 과정을 통해 조립된 다음 상기에서 언급한 케이스에 장착된다.The LCD module having these components is assembled through the assembly process and then mounted in the above-mentioned case.

LCD 모듈이 장착되어 제조 완료된 LCD 장치는 통상 휴대성을 위해 경박단소화, 경량화된다.An LCD device manufactured by mounting an LCD module is usually light and small and lightweight for portability.

이렇게 휴대할 수 있는 LCD 장치는 휴대성이라는 특수성 때문에 테이블용 피시(pc)보다 강한 내구성을 요한다.Such portable LCD devices require stronger durability than table PCs because of their portability.

이는 사용자의 LCD 장치 휴대시 외부로부터 가해지는 충격이 다른 피시에 비해 보다 빈번하게 발생되기 때문이다.This is because an impact from the outside occurs more frequently than other fish when the user carries the LCD device.

특히, 데이터를 디스플레이하는 LCD 모듈에 대한 내구성 강화는 더욱 요구되고 있다. In particular, there is a further demand for enhanced durability of LCD modules displaying data.

그러나, 외부에서 소정의 충격이 케이스에 가해질 경우, 케이스에 장착된 LCD 모듈로 파급되는 외부 충격을 흡수하는 제재 요소 없기 때문에 LCD 모듈에 외부 충격이 그대로 전달되어 제품의 신뢰성이 저하되는 문제점이 있었다.However, when a predetermined shock is applied to the case from the outside, there is a problem that the external shock is transmitted to the LCD module as it is, because there is no sanitizing element that absorbs the external shock spread to the LCD module mounted on the case, thereby reducing the reliability of the product.

따라서, 본 발명의 목적은 LCD 모듈로 전달되는 소정의 충격을 흡수할 수 있도록 하는데 있다.Therefore, an object of the present invention is to be able to absorb a predetermined shock delivered to the LCD module.

본 발명의 다른 목적은 다음의 상세한 설명과 첨부된 도면으로부터 보다 명확해질 것이다.Other objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

이와 같은 목적을 달성하기 위해서 본 발명은 몰드 프레임의 소정영역에 완충부가 설치하여 외부로부터 LCD 모듈에 가해지는 소정의 충격을 완충하도록 한다.In order to achieve the above object, the present invention provides a shock absorbing part in a predetermined area of the mold frame to cushion a predetermined shock applied to the LCD module from the outside.

이때, 완충부는 몰드 프레임의 하부면 소정 영역에 형성된 수납홈에 수납 설치되어 몰드 프레임의 하부면보다 소정 높이 돌출되는 완충고무를 포함하여 구성될 수 있다.In this case, the buffer unit may be configured to include a buffer rubber that is installed in the receiving groove formed in a predetermined region of the lower surface of the mold frame protruding a predetermined height than the lower surface of the mold frame.

이하 첨부된 도면을 참조하여 본 발명의 기술에 따른 실시예에 의한 LCD 모듈을 보다 상세하게 설명하면 다음과 같다.Hereinafter, an LCD module according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1, 도 2를 참조하면, 도광판(10)의 일측에는 광을 발생시키는 램프 어셈블리(12)가 설치되고, 도광판(10)의 하부에는 광을 반사하는 반사시트(도시되지 않음)가 설치된다. 도광판(10)의 상부에는 광을 확산하는 확산시트와 광을 집광하는 프리즘시트와 프리즘시트의 표면을 보호하는 보호시트가 순서대로 적층되어 이루어진 시트류들(14)이 설치된다.1 and 2, a lamp assembly 12 for generating light is installed at one side of the light guide plate 10, and a reflective sheet (not shown) for reflecting light is installed at a lower part of the light guide plate 10. . On the upper part of the light guide plate 10, sheet sheets 14 formed of a diffusion sheet for diffusing light, a prism sheet for collecting light, and a protective sheet for protecting the surface of the prism sheet are sequentially stacked.

몰드 프레임(16)은 'ㄱ'자 단면형상으로 램프 어셈블리(12)의 측면과 하부면 및 반사시트의 하부면 가장자리 영역을 감싸도록 설치된다.The mold frame 16 is installed to surround the side and bottom surfaces of the lamp assembly 12 and the bottom surface edge region of the reflective sheet in a '-' cross-sectional shape.

이때, 본 발명에 따르면, 몰드 프레임(16)의 하부면 소정 영역에 완충부(18)가 설치된다.At this time, according to the present invention, the buffer unit 18 is provided in a predetermined region of the lower surface of the mold frame 16.

완충부(18)는 완충고무(20)가 몰드 프레임(16)의 하부면에 형성된 수납홀(22)에 수납 설치되도록 이루어진다. 이때, 외부로 표출되는 완충고무(20)의 일측단부는 몰드 프레임(16)의 하부면보다 소정 길이 높게 돌출된다.The shock absorbing portion 18 is configured such that the shock absorbing rubber 20 is accommodated and installed in the receiving hole 22 formed in the lower surface of the mold frame 16. At this time, one side end of the buffer rubber 20 to be exposed to the outside protrudes a predetermined length higher than the lower surface of the mold frame 16.

이렇게 설치된 완충부(18)는 외부로부터 LCD 모듈에 가해지는 소정의 충격을 흡수하여 완충하는 역할을 한다.The buffer unit 18 thus installed serves to absorb and cushion a predetermined shock applied to the LCD module from the outside.

시트류(14)들의 상부에 위치하는 LCD 패널(24)은 몰드플레임(16)의 상부면의 소정 영역에 놓여져 설치된다. 탑 샷시(26)는 LCD 패널(24)의 상부면 가장자리와 몰드 프레임(16)의 측면을 감싸면서 몰드 프레임(16)에 고정되어 LCD 패널(24)을 지지한다.The LCD panel 24 located above the sheets 14 is placed in a predetermined area of the upper surface of the mold frame 16. The top chassis 26 is fixed to the mold frame 16 while surrounding the upper edge of the LCD panel 24 and the side of the mold frame 16 to support the LCD panel 24.

램프 어셈블리(12)는 램프(28)와 램프(28)를 감싸면서 램프(28)로부터 발생되는 광을 도광판(10) 방향으로 반사시키는 램프 커버(30)와 램프(28)의 양측단부 영역에 설치되어 램프 커버(30)내에 끼워져 램프(28)의 유동을 방지하는 램프 홀더(32)로 이루어진다.The lamp assembly 12 surrounds the lamp 28 and the lamp 28 and covers the lamp cover 30 and the opposite end regions of the lamp 28 to reflect the light generated from the lamp 28 toward the light guide plate 10. It is made of a lamp holder 32 is installed in the lamp cover 30 to prevent the flow of the lamp 28.

이러한 구조로 이루어진 LCD 모듈은 차후 케이스에 장착되며, 외부로부터 소정의 충격이 가해질 경우, LCD 모듈에 설치된 완충부에서 우선적으로 충격을 완충하기 때문에 LCD 모듈에 가해지는 충격이 최소화된다.The LCD module having such a structure is mounted on the case later, and when a predetermined shock is applied from the outside, the shock applied to the LCD module is minimized because the shock is preferentially buffered in the buffer unit installed in the LCD module.

한편, 본 실시예에서는 몰드 프레임의 하부면에 설치된 완충부를 갖는 LCD 모듈에 대해 설명하였지만, 완충부의 설치 위치는 몰드 프레임의 하부면 이외에 다른 위치에 설치될 수도 있다. 이에 따른 완충부의 작용 및 완충 효과는 상기에서 설명한 실시예와 동일하다.On the other hand, in the present embodiment has been described with respect to the LCD module having a shock absorbing portion provided on the lower surface of the mold frame, the mounting position of the shock absorbing portion may be provided in a position other than the lower surface of the mold frame. The action and the buffering effect of the buffer according to this is the same as the embodiment described above.

이상에서 살펴본 바와 같이 본 발명은 몰드 프레임의 외측면 소정 영역에 완충부가 설치되어 외부로부터 가해지는 충격을 흡수하여 완충함으로써 외부 충격으로 인해 발생되는 LCD 모듈의 작동 불량이 최소화되어 제품의 신뢰성이 향상되는 효과가 있다.As described above, in the present invention, the buffer unit is installed on a predetermined area of the outer surface of the mold frame to absorb and cushion the shock applied from the outside, thereby minimizing the malfunction of the LCD module caused by the external impact, thereby improving the reliability of the product. It works.
