컴퓨터는 데스크탑컴퓨터와, 휴대용 컴퓨터 등 여러 가지로 분류될 수 있고, 컴퓨터는 입력장치, 기억장치, 연산장치, 그리고 상기 연산장치의 연산결과를 표시하는 화상표시장치를 기본적으로 구비하고 있다.Computers can be classified into various types such as desktop computers and portable computers. Computers are basically provided with an input device, a storage device, a computing device, and an image display device for displaying the calculation results of the computing device.

화상표시장치 또는 모니터는 데스크탑에서는 음극선관(CRT: Cathode Ray Tube)이 주로 사용되고 휴대용 컴퓨터에서는 액정표시장치(LCD)가 주로 사용되고 있다.Cathode ray tubes (CRTs) are mainly used for image displays or monitors, and liquid crystal displays (LCDs) are mainly used for portable computers.

최근 데스크탑컴퓨터에도 CRT를 대신하여 눈에 피로가 적고, 전자파발생이 거의 없는 액정표시장치가 사용되고 있으므로, 이러한 구분은 점점 그 의미가 옅어지고 있다.Recently, the liquid crystal display device with less eye fatigue and little electromagnetic wave generation has been used in place of the CRT in desktop computers, and this distinction is becoming thinner.

본 발명은 상기와 같이 다양한 컴퓨터에 적용될 수 있는 화상표시장치에 관한 것으로, 특히 배광장치와 LCD패널로 이루어진 액정표시장치의 결합구조에 관한 것이다.The present invention relates to an image display device that can be applied to various computers as described above, and more particularly, to a coupling structure of a liquid crystal display device including a light distribution device and an LCD panel.

And the liquid crystal panel 112 are sequentially stacked. On the other hand, the main frame 115 is coupled to the top frame 116 of the metal material on the upper side of the liquid crystal panel 112.

좀더 상세히 살펴보면, 액정패널(112)에는 가장자리부를 따라 액정패널의 구동회로인 인쇄회로기판(printed circuit board: 이하 PCB라 칭함)(101)이 탑재되어 있고, 반사판(114e)의 일측에는 램프하우징(113)이 위치하고 있다.In more detail, the liquid crystal panel 112 includes a printed circuit board 101 which is a driving circuit of the liquid crystal panel along an edge thereof, and a lamp housing (1) of one side of the reflecting plate 114e. 113 is located.

한편, 상기 메인프레임(main frame)은 메인서포터(main supporter)이라고도 불리우며, 상기 탑프레임(top frame)은 탑케이스(top case)라고도 불리운다.On the other hand, the main frame is also called a main supporter, and the top frame is also called a top case.

이러한 액정표시장치모듈의 PCB(101)와 램프하우징(113)에는 전자파가 발생하게 되므로 노이즈에 의한 소자의 동작특성저하를 방지하기 위하여 접지시켜야 하고, 주로 금속재질인 탑프레임(116)에 접지하게 된다.Since the electromagnetic wave is generated in the PCB 101 and the lamp housing 113 of the liquid crystal display module, it should be grounded in order to prevent deterioration of the operation characteristics of the device due to noise. do.

이러한 액정표시장치모듈의 표시부의 평면도는 도 2, 배면도는 도 4에 도시되어 있고, 종래의 접지구조를 도2 내지 도 4를 참조하여 설명한다.2 is a plan view of the display unit of the liquid crystal display device module, and a rear view thereof is shown in FIG. 4, and a conventional grounding structure will be described with reference to FIGS. 2 to 4.

Since it is located, the ground plate 111 connected to the lower portion of the lamp housing 113 is bent and grounded with the top frame 116 past the outer vertical portion 115a of the main frame 115. At this time, the ground plate 111 is naturally a metal plate, and the top frame and the grounded portion 111a are bent to contact each other using elasticity. Here, reference numeral 112 denotes a liquid crystal panel.

한편, 액정표시장치모듈의 배면도인 도 4를 참조하여 PCB와 탑프레임과의 접지관계를 살펴보면, 도시한 바와 같이, 두 개의 PCB(101a)(101b)는 각각 도전성테이프(118)를 통하여 탑프레임(116)과 접지된다.Meanwhile, referring to FIG. 4, which is a rear view of the LCD module, referring to the ground relationship between the PCB and the top frame, as shown in the drawings, the two PCBs 101a and 101b may each have a top through the conductive tape 118. It is grounded with the frame 116.

그런데 상기와 같은 종래의 접지구조에서는 도 3에서와 같이 램프하우징과 탑프레임을 접지하고, 도 4에서와 같이, PCB와 탑프레임을 접지하는 등 서로 분리된 구조물을 사용하여 접지하고 있으므로, 생산능률이 저하되고, 부품수가 증가되고, 분해조립성이 떨어지는 문제가 있게된다.However, in the conventional grounding structure as described above, the lamp housing and the top frame are grounded as shown in FIG. 3, and as shown in FIG. This lowers the number of parts, increases the number of parts, and degrades disassembly.

특히 도전성테이프를 이용함으로써 분해조립성에 좋지못한 결과를 초래하게 된다.In particular, the use of conductive tapes may result in poor disassembly and assembly.

도시한 바와 같이, 각 연결부(11)(21)(31)의 끝단은 몸체에서 분기되어 연장되는 다수개의 브랜치(branch)형상으로, 핑거(finger) 또는 바(bar)라고도 지칭될 수 있는데 이 명세서에서는 브랜치(12)(22)(33)로 통일하여 부르기로 한다. 이는 램프하우징, 탑프레임, PCB와 결합되기 위한 탄성력을 증대시키고, 금속재질인 하나의 브랜치가 어떤 충격에 의해 원하지 않는 방향으로 절곡되어 접촉이 끊어지더라도 다른 브랜치가 접촉할 수 있기 때문에 접지의 안전성을 위해서도 필요하다.As shown, the ends of each connecting portion 11, 21, 31 are in the form of a number of branches branching out of the body, which may also be referred to as a finger or a bar. In the following description, the branches 12, 22, and 33 are collectively called. This increases the elasticity to be combined with the lamp housing, the top frame, and the PCB, and the safety of grounding is possible because one branch, which is made of metal, may be bent in an undesired direction by a certain impact and the other branch may be contacted even if the contact is broken. It is also necessary for.

각 브랜치(12)(22)(33)는 대체로 평행하게 배열되도록 형성되어 있는 것이 제작의 편의상 유리하고, 제품의 균일성을 담보할 수 있으나, 이에 한정되는 것은 아니다.Each branch 12, 22, 33 is formed to be generally arranged in parallel, it is advantageous for the convenience of manufacturing, and may ensure the uniformity of the product, but is not limited thereto.

이는 탄성부(33)가 다시 복원하려는 탄성복원력을 이용하여 탑프레임과의 접촉을 용이하게 하기 위함이다.This is to facilitate the contact with the top frame by using the elastic restoring force that the elastic portion 33 is to restore again.

상기에서 각 연결부의 접촉부 즉, 브랜치는 일부가 돌출굴곡되어 있고, 일부는 접철되어 있으나, 이는 예시이고, 접촉부의 형상은 본 발명의 한정이 아님은 물론이다.In the above, the contact portion, that is, the branch of each connection portion is protruded and bent, but is partially folded, but this is an example, and the shape of the contact portion is not a limitation of the present invention, of course.

This bent portion 22a of the branch 22 allows a smooth contact with the PCB 101, so that a more reliable contact is possible than the flat plate structure.

한편, 탑프레임(116)과 연결되는 제 3연결부(31)는 메인프레임(115)과 탑프레임(116)의 수직부(116a) 사이에 위치하도록 직각으로 절곡된 절곡부(32)와, 절곡부끝단에서 소정각도 접히도록 형성된 탄성부(33)인 다수개의 브랜치로 되어 있고, 이 제 3연결부(31)의 브랜치(33)가 상기 제 1, 2연결부의 브랜치와 달리 접혀져 있는 것은 본 발명에 따른 접지플레이트가 메인프레임과 탑프레임 사이에 끼워져야 하기 때문에 장착의 편의를 도모하기 위함이다.On the other hand, the third connecting portion 31 is connected to the top frame 116 is bent portion 32 bent at a right angle to be located between the main frame 115 and the vertical portion 116a of the top frame 116, and bent It is composed of a plurality of branches, which are elastic portions 33 formed to be folded at a predetermined angle at the end, and the branch 33 of the third connecting portion 31 is folded unlike the branches of the first and second connecting portions in the present invention. The ground plate according to this should be fitted between the main frame and the top frame for the convenience of mounting.

이상에서 살펴본 바와 같이, 본 발명에 따른 접지플레이트를 적용한 액정표시장치모듈은 접지를 위해 도전성 테이프를 사용하지 않음으로, 분해조립성을 향상시킬 수 있는 잇점이 있다.As described above, the liquid crystal display device module to which the ground plate according to the present invention is applied does not use a conductive tape for grounding, and thus, there is an advantage of improving disassembly and assembly.

또한, PCB와 램프하우징과, 탑프레임을 동시에 접지시킬 수 있으므로, 접지를 위해 최소한의 부품만을 사용하게 되는 잇점이 있다.In addition, the PCB, lamp housing and top frame can be grounded at the same time, so there is an advantage of using only a minimum of components for grounding.

또한 본 발명의 지지플레이트는 위치를 잡아 스크루결합만으로 조립할 수 있으므로 조립성도 향상된다는 잇점이 있다.In addition, the support plate of the present invention has the advantage that the assembly is also improved because it can be assembled by screwing only the position.

이상에서 본 발명에 따른 실시예를 설명하였으나, 상기에서 설명한 본 발명의 실시예는 단지 예시이며, 본 발명의 정신을 벗어나지 않고 다양한 변화와 변형이 가능할 것임은 본 발명이 속한 분야의 통상의 지식인은 알 수 있을 것이다. 예를들어 본 발명은 휴대용 컴퓨터 뿐만 아니라 데스크탑컴퓨터 등에서도 적용됨은 앞에서 설명한 바와 같다.While the embodiments of the present invention have been described above, the embodiments of the present invention described above are merely exemplary, and various changes and modifications may be made without departing from the spirit of the present invention. You will know. For example, the present invention is applicable to a desktop computer as well as a portable computer as described above.

또한, 또 다른 PCB를 접지하여야 하는 경우에는 별도의 접지플레이트를 사용할 수도 있고, 이때는 그 PCB와 탑프레임을 접지시키기 위한 간단한 접지플레이트를 하나 더 사용할 수 있음은 물론이다.In addition, when another PCB needs to be grounded, a separate ground plate may be used, and in this case, one simple ground plate for grounding the PCB and the top frame may be used.

또한, 상기 각 연결부의 브랜치의 개수는 2, 3, 4개 등으로 주변설계조건을 고려하여 변형이 가능하다.In addition, the number of branches of each of the connecting portion is 2, 3, 4, etc. can be modified in consideration of the peripheral design conditions.

그러나, 이러한 변화와 변형은 모두 본 발명의 권리범위에 속하게 됨은 첨부된 특허청구의 범위를 통해 알 수 있을 것이다.However, it will be apparent from the scope of the appended claims that all such changes and modifications fall within the scope of the present invention.
