Description
본 발명은 액정표시장치(LCD)에 관한 것으로, 특히 액정표시장치를 구성하는 LCD 모듈의 각 구성요소들의 모서리를 둘러싸며 고정되게 지지하여주는 금속 프레임에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display (LCD), and more particularly, to a metal frame that is fixedly supported by surrounding corners of components of an LCD module constituting the liquid crystal display.
일반적으로, 평판형 표시장치의 하나인 액정디스플레이(LCD)는 음극선관(CRT)에 비해 시인성이 우수하고 평균소비전력도 같은 화면크기의 CRT에 비해 작을 뿐만 아니라 발열량도 작기 때문에 플라즈마표시장치(PDP: Plasma Display Panel)나 전계방출표시장치(FED:Field Emission Display)와 함께 최근에 휴대폰이나 컴퓨터의 모니터, 텔레비젼의 차세대 표시장치로서 각광받고 있다.In general, a liquid crystal display (LCD), which is one of flat panel display devices, has a higher visibility than a cathode ray tube (CRT) and has a smaller average heat dissipation than a CRT having the same screen size. Along with Plasma Display Panel (FED) and Field Emission Display (FED), it has recently been in the spotlight as the next generation display device for monitors of mobile phones, computers, and televisions.
이러한 액정표시장치(LCD)는 특수하게 표면처리된 2개의 얇은 유리판 사이에 고체와 액체의 중간물질인 액정물질을 주입해 상하 유리판 위의 전극의 전압차로 액정분자의 배열을 변화시킴으로써 명암을 발생시켜 영상을 표시하는 작동원리를 갖는다.The liquid crystal display (LCD) generates a contrast by injecting a liquid crystal material, which is an intermediate between solid and liquid, between two thin glass plates that have been specially treated and changing the arrangement of liquid crystal molecules by a voltage difference between electrodes on the upper and lower glass plates. It has an operating principle for displaying an image.
통상적으로, 액정표시장치를 이루는 LCD 모듈은 화면을 출력하는 액정패널과, 이 액정패널 후면에서 액정패널에 광원을 제공하는 백라이트 어셈블리(backlight assembly), 외부로부터 영상신호 등을 받아 액정패널에 원하는 화면을 구현하는 구동회로부 및, 이들 구성요소들을 지지하는 몰드프레임 및 금속 프레임 등의 지지부재로 이루어진다.In general, an LCD module constituting a liquid crystal display device includes a liquid crystal panel for outputting a screen, a backlight assembly for providing a light source to the liquid crystal panel at the rear of the liquid crystal panel, and receiving a video signal from the outside. And a support member such as a mold frame and a metal frame for supporting these components.
첨부된 도면의 도 1과 도 2는 노트북 컴퓨터의 화면표시장치를 구성하는 LCD 모듈의 구성요소들을 상세히 나타낸 것으로, 영상을 출력하는 액정패널(10)의 후면에는 백라이트 어셈블리(20)를 구성하는 상,하부 확산시이트(21, 23) 및 상,하부프리즘시이트(22, 24)와, 도광판(25)과, 반사시이트(26)가 차례로 배치되어 사각틀 형태의 플라스틱 몰드프레임(30) 상에 얹혀져 지지되고, 상기 몰드프레임(30)의 일측 모서리에는 빛을 방출하는 램프(27)가 설치되며, 상기 액정패널(10)과 백라이트 어셈블리(20) 및 몰드프레임(30)은 몰드프레임(30) 위쪽에서 결합되는 사각틀 형태의 금속 프레임(40)에 의해 서로 결합되어 지지된다.1 and 2 of the accompanying drawings showing in detail the components of the LCD module constituting the display device of the notebook computer, the image forming the backlight assembly 20 on the back of the liquid crystal panel 10 for outputting an image The lower diffusion sheets 21 and 23, the upper and lower prism sheets 22 and 24, the light guide plate 25, and the reflective sheet 26 are sequentially disposed to be mounted on the plastic mold frame 30 having a rectangular frame shape. In addition, a lamp 27 for emitting light is installed at one edge of the mold frame 30, and the liquid crystal panel 10, the backlight assembly 20, and the mold frame 30 are disposed above the mold frame 30. It is coupled to each other by a metal frame 40 of the rectangular frame shape to be coupled to each other.
그런데, 상기와 같은 종래의 액정표시장치는 상기 액정패널(10)과 백라이트 어셈블리(20)를 결합시켜 주는 구조물이 사각틀 형태로 일체로 된 금속 프레임(40)으로 이루어지는 바, 금속 프레임이 항상 몰드프레임(30)의 위쪽에서부터 결합되므로 항상 'ㄱ'자 단면을 가질 수 박에 없고 이에 따라 지지강도가 약해 도 2에 도시된 것과 같이 몰드프레임(30) 하부면 일측 모서리를 따라 SUS재질로 된 별도의 보강부재(45)를 부착해야 했고, 이로 인해 LCD 모듈이 무거워짐과 더불어 조립작업이 복잡해지고 비용이 증가되는 문제점이 있었다.However, the conventional liquid crystal display device as described above is formed of a metal frame 40 in which a structure for coupling the liquid crystal panel 10 and the backlight assembly 20 is integrally formed in a rectangular frame, and the metal frame is always a mold frame. Since it is coupled from the top of the (30) is not always in the watermelon having a 'c' cross-section, and thus the supporting strength is weak, as shown in Figure 2, along the one side edge of the lower surface of the mold frame 30 is made of SUS material The reinforcing member 45 had to be attached, and as a result, the LCD module became heavy and the assembly work was complicated and the cost was increased.
또한, 금속 프레임을 제작하는 과정에서 프레임 중간의 개방부를 프레싱하여 절단하는 작업(piercing)을 수행하기 때문에 재료의 낭비가 심하고, 금속 프레임이 일체형이므로 트랜스퍼(transfer) 금형을 사용하여 제작하기 때문에 제작비용이 많이 소요되는 문제점도 있었다.In addition, in the process of fabricating the metal frame, pressing the cutting of the opening in the middle of the frame (piercing) is a waste of material, and since the metal frame is an integral type, using a transfer mold to manufacture the production cost There was also a lot of trouble.
이에 본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로, 액정표시장치의 액정패널과 백라이트 어셈블리 및 몰드프레임을 결합하여 주는 프레임의 구조를 개선하여 별도의 보강물없이 충분한 지지강도를 보장할 수 있으며, 몰드프레임과의 조립성이 향상되고, 제작면에서도 유리한 액정표시장치용 프레임을 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, by improving the structure of the frame that combines the liquid crystal panel, the backlight assembly and the mold frame of the liquid crystal display device can ensure sufficient support strength without additional reinforcement In addition, the object of the present invention is to provide a frame for a liquid crystal display device which is improved in assembling with a mold frame and is advantageous in production.

It is composed of a lamp 27 which is a light emitting body is installed in the lower edge portion of the frame 30, this configuration of the backlight assembly 20 is the same as the conventional LCD module configuration.
상기 제 1프레임 부재(410)와 제 2프레임 부재(420)는 액정패널(10) 및 몰드프레임(30) 모서리부분에 결합되었을 때 이들 모서리부 전체를 둘러싸며 전체적으로 사각틀 형태를 이루게 된다.When the first frame member 410 and the second frame member 420 are coupled to the corner portions of the liquid crystal panel 10 and the mold frame 30, the first frame member 410 and the second frame member 420 form a rectangular frame as a whole.
그리고, 제 1프레임 부재(410)와 제 2프레임 부재(420)는 각각 몰드프레임(30)의 상단 및 하단 모서리부와 결합하게 되는 부분은 'ㄷ'자형 단면을 가지며, 몰드프레임(30)의 양측 모서리와 결합하게 되는 부분은 'ㄱ'자형 단면을 갖도록 되어 있다.In addition, the first frame member 410 and the second frame member 420, respectively, the portion to be combined with the upper and lower edges of the mold frame 30 has a '' 'cross-section, of the mold frame 30 The part to be joined to both edges is to have a '-' cross section.
따라서, 제 1프레임 부재(410)와 제 2프레임 부재(420)가 액정패널(10) 및 몰드프레임(30)에 결합될 때 이들의 상단 및 하단 모서리의 전면 및 후면부를 감싸면서 결합하게 된다.Accordingly, when the first frame member 410 and the second frame member 420 are coupled to the liquid crystal panel 10 and the mold frame 30, the first frame member 410 and the second frame member 420 are combined to surround the front and rear portions of the upper and lower edges thereof.
또한, 제 1프레임 부재(410)와 제 2프레임 부재(420)의 각 끝단부에는 내측으로 절곡된 결합편(411, 412)(421, 422)들이 일체로 형성되는데, 이들 각 프레임부재(410, 420)들의 결합편(411, 412)(421, 422)들은 몰드프레임(30)의 양측 모서리부분에 각각 형성된 결합홈(35)에 함께 맞대어져 압입 결합되며, 이로써 제 1프레임 부재(410)와 제 2프레임 부재(420)는 몰드프레임(30)에 견고하게 결합된다.In addition, at each end of the first frame member 410 and the second frame member 420, coupling pieces 411, 412, 421, and 422 that are bent inwardly are integrally formed. Coupling pieces 411, 412, 421, 422 of the 420 are butt-coupled to the coupling grooves 35 respectively formed at both corners of the mold frame 30 to press-fit the first frame member 410. And the second frame member 420 are firmly coupled to the mold frame 30.
상기 제 1프레임 부재(410)와 제 2프레임 부재(420)가 결합된 몰드프레임(30) 후면부 상단 및 하단에는 제 1,2프레임 부재(410, 420)들을 따라 테이프(430)가 부착되는데, 이는 제 1,2프레임 부재(410, 420)의 지지강도를 더욱 증대시킴으로써 LCD 모듈이 외부로부터 충격을 받더라도 제 1,2프레임 부재(410, 420)가 몰드프레임(30)과 분리되는 현상을 최대한 억제할 수 있도록 하기 위함이다.Tapes 430 are attached to upper and lower ends of the rear surface of the mold frame 30 to which the first frame member 410 and the second frame member 420 are coupled, along the first and second frame members 410 and 420. This further increases the supporting strength of the first and second frame members 410 and 420 so that the first and second frame members 410 and 420 are separated from the mold frame 30 even when the LCD module is impacted from the outside. To suppress it.
상기 제 1프레임 부재(410)와 제 2프레림 부재(420)는 종래의 프레임의 개방부를 형성하기 위한 천공작업이 필요치 않으므로 트랜스퍼 금형에 비해 가격이 싼프로그레시브(progressive) 금형에 의해 제작이 가능하고, 이에 따라 재료의 낭비를 줄이고 제작 단가를 줄일 수 있다.Since the first frame member 410 and the second frame member 420 do not require a punching operation to form an opening of a conventional frame, the first frame member 410 and the second frame member 420 may be manufactured by a progressive mold, which is cheaper than a transfer mold. Therefore, it is possible to reduce the waste of materials and the manufacturing cost.
상기와 같이 구성된 프레임 부재(410, 420)들을 구비한 LCD 모듈의 조립 과정에 대해 간략히 설명하면, 먼저, 몰드프레임(30)에 램프(27)를 비롯하여 백라이트 어셈블리(20)를 설치한 후 그 위에 액정패널(10)을 안착시키고, 이어서 제 1프레임 부재(410)와 제 2프레임 부재(420)를 몰드프레임(30)의 측면부에서부터 끼워넣어 조립하게 되는데, 이 때 각 프레임 부재(410, 420)들의 결합편(411, 412)(421, 422)들이 몰드프레임(30) 양측에 마련된 결합홈(35)에 삽입되면서 결합된다.The assembly process of the LCD module having the frame members 410 and 420 configured as described above will be briefly described. First, the lamp assembly 27 and the backlight assembly 20 are installed in the mold frame 30 and thereafter. The liquid crystal panel 10 is seated, and then the first frame member 410 and the second frame member 420 are assembled from the side portions of the mold frame 30, whereby the respective frame members 410 and 420 are assembled. Coupling pieces 411, 412, 421, 422 are coupled to the coupling grooves 35 provided on both sides of the mold frame 30.
상기와 같이 제 1,2프레임 부재(410, 420)들이 몰드프레임(30)에 결합되면, 제 1,2프레임 부재(410, 420)들은 액정패널(10)과 몰드프레임(30)의 모서리를 둘러싸며 지지하게 되는데, 여기서, 상기 몰드프레임(30) 상단 및 하단 모서리부와 결합되는 제 1,2프레임 부재(410, 420) 부분들은 'ㄷ'자형 단면을 갖고 있음에 따라 몰드프레임(30) 상단 및 하단 모서리부의 전면부 및 후면부를 동시에 감싸며 지지하게 되고, 이로써 별도의 보강부재 없이도 몰드프레임(30)과 액정패널(10)을 견고하고 지지할 수 있는 지지강도를 확보하게 된다.When the first and second frame members 410 and 420 are coupled to the mold frame 30 as described above, the first and second frame members 410 and 420 may form corners of the liquid crystal panel 10 and the mold frame 30. In this case, the first and second frame members 410 and 420 coupled to the upper and lower edge portions of the mold frame 30 have a 'c' shaped cross section, thereby supporting the mold frame 30. The front and rear edges of the upper and lower edge portions are simultaneously wrapped and supported, thereby securing a supporting strength capable of firmly and supporting the mold frame 30 and the liquid crystal panel 10 without a separate reinforcing member.
한편, 전술한 실시예에서는 제 1,2프레임 부재(410, 420)들은 그의 결합편(411, 412, 421, 422)들이 몰드프레임(30)의 결합홈(35)에 삽입되어 결합됨으로써 몰드프레임(30) 상에 견고히 결합된 것으로 설명하였으나, 이와는 다르게 각 프레임 부재와 몰드프레임에 별도의 결합수단, 예컨대 후크와 이 후크와 결합되는 걸림홈 등이 적소에 구비되어 결합될 수도 있을 것이다.Meanwhile, in the above-described embodiment, the first and second frame members 410 and 420 are coupled to the coupling pieces 411, 412, 421 and 422 by being inserted into and coupled to the coupling groove 35 of the mold frame 30. Although it was described as firmly coupled to 30, alternatively, a separate coupling means, for example, a hook and a locking groove coupled to the hook, may be provided in place and coupled to each frame member and the mold frame.
이상에서와 같이 본 발명에 따르면, LCD모듈의 몰드프레임과 액정패널을 지지하는 금속 프레임이 일체로 형성되지 않고 복수개로 분할된 프레임 부재로 이루어지므로, 프레임을 몰드프레임의 측면에서부터 조립하는 것이 가능하여 프레임 부재의 단면을 'ㄷ'자 등의 지지강도 확보에 유리한 형태로 자유롭게 형성할 수 있게 되고, 이에 따라 종래와 같은 별도 보강물을 사용하지 않고 충분한 지지강도를 확보할 수 있으므로 액정표시장치의 무게를 줄일 수 있으며, 조립성도 향상시킬 수 있다.As described above, according to the present invention, since the mold frame of the LCD module and the metal frame supporting the liquid crystal panel are not integrally formed and are formed of a plurality of divided frame members, the frame can be assembled from the side of the mold frame. The cross section of the frame member can be freely formed in a form advantageous for securing the supporting strength of the letter 'c', etc. As a result, sufficient support strength can be secured without using a separate reinforcement as in the prior art, so that the weight of the liquid crystal display device It can reduce and improve the assemblability.
또한, 각 프레임 부재들을 제작함에 있어서도, 종래의 프레임의 개방부를 형성하기 위한 천공작업이 필요치 않으므로 트랜스퍼 금형에 비해 가격이 싼프로그레시브(progressive) 금형에 의해 제작이 가능하고, 이에 따라 재료의 낭비를 줄이고 제작 단가를 줄일 수 있는 이점도 얻게 된다.In addition, even in manufacturing the respective frame members, it is possible to manufacture by using a progressive mold, which is cheaper than the transfer mold, because a conventional drilling operation for forming the opening of the frame is not required, thereby reducing waste of materials. It also has the advantage of reducing manufacturing costs.
