본 발명은 액정모듈의 이중샤시구조에 관한 것이다.The present invention relates to a double chassis structure of a liquid crystal module.

일반적인 액정패널은 통상 2매의 도전성 유리판재를 평행하게 배치하고, 그 사이에 유전이방성(誘電異方性)을 갖는 액정을 주입하여, 외부로부터 인가되는 전압 변화에 따라 달라지는 액정의 광반사 성질을 이용해 각종 화면을 디스플레이하는 방식이다.A general liquid crystal panel usually arranges two conductive glass plates in parallel, injects liquid crystals having dielectric anisotropy therebetween, and exhibits light reflecting properties of liquid crystals that vary with voltage changes applied from the outside. It is a method of displaying various screens by using.

아울러 백라이트 유닛은 광을 발생하는 광원 및 발생된 광을 액정패널로 안내하기 위한 도광판을 포함한다. 상기 광원은 상기 도광판의 일측면(혹은 양측면)에 위치하며, 발광 다이오드(Light Emitting Diode, 이하 LED)로 형성된다.In addition, the backlight unit includes a light source for generating light and a light guide plate for guiding the generated light to the liquid crystal panel. The light source is positioned on one side (or both sides) of the light guide plate and is formed of a light emitting diode (LED).

이하, 종래의 액정표시장치 각 구성부와 이들 구성부가 갖는 단점을 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, each component of the conventional liquid crystal display and its disadvantages will be described in detail with reference to the accompanying drawings.

도 1은 종래 평판표시장치의 일종인 액정표시장치의 구성을 나타낸 정면도이며, 도 2는 도 1의 결합구조를 나타낸 단면도이다.1 is a front view illustrating a configuration of a liquid crystal display device which is a type of a conventional flat panel display device, and FIG. 2 is a cross-sectional view illustrating a coupling structure of FIG. 1.

종래의 액정모듈은 도 1 및 도 2의 도시와 같이 2매의 도전성 유리판재 사이에 액정물질이 채워진 액정패널(10)과, 상기 액정패널(10)의 후방에 설치되어 액정패널(10)에 빛을 제공하는 백라이트유닛(BLU)(20)과, 상기 액정패널(10)과 백라이트유닛(20)을 지지 고정하는 몰드프레임(30)과, 상기 몰드프레임(30)의 일부를 감싸도록 설치되는 샤시(40)를 포함하여 구성되어 상기 액정패널(10)과 백라이트유닛(20)은 몰드프레임(30) 내에 수용되어 지지 고정되고, 상기 몰드프레임(30)을 샤시(40)가 감싸도록 조립된다.The conventional liquid crystal module has a liquid crystal panel 10 filled with a liquid crystal material between two conductive glass sheets as shown in FIGS. 1 and 2, and is installed at a rear side of the liquid crystal panel 10 to provide a liquid crystal panel 10. The backlight unit (BLU) 20 for providing light, the mold frame 30 for supporting and fixing the liquid crystal panel 10 and the backlight unit 20, and is installed to surround a part of the mold frame 30 The liquid crystal panel 10 and the backlight unit 20 are configured to include the chassis 40 so that the liquid crystal panel 10 and the backlight unit 20 are accommodated and fixed in the mold frame 30, and the chassis 40 is assembled to surround the mold frame 30. .

이와 같이 구성되는 종래의 액정모듈은 주로 휴대단말기 등의 디스플레이장치로 사용되고 있으며, 투명한 재질로 형성되는 보호창(50)에 의해 보호되는 구조로 단말기 내에 장착된다.The conventional liquid crystal module configured as described above is mainly used as a display device such as a mobile terminal, and is mounted in a terminal in a structure protected by a protective window 50 formed of a transparent material.

그러나, 종래의 액정모듈은 몰드프레임(30)의 강성이 취약하게 되어 몰드프레임(30)의 휨 변형 발생시 액정패널(10)에 크랙(CRACK)현상이 일어나는 문제점이 있었으나, 이는 샤시(40)를 적용하여 몰드프레임(30)의 휨변형을 방지하여 3-포인트 벤딩 강도 및 폰 세트 상태에서의 낙하실험(DROP TEST)에 따른 액정패널(10)의 크랙(CRACK)은 어느 정도 개선할 수 있었지만, 액정모듈 COG(Chip On Glass) 정압시험에 의한 강도 개선에는 부족했다.However, the conventional liquid crystal module has a problem in that the rigidity of the mold frame 30 is weak and cracks occur in the liquid crystal panel 10 when the bending deformation of the mold frame 30 occurs. By applying the bending deformation of the mold frame 30 to prevent the bending of the liquid crystal panel 10 according to the drop test (DROP TEST) in the three-point bending strength and the phone set state to some extent, The strength improvement by the COG (Chip On Glass) positive pressure test was insufficient.

또한, 휴대단말기의 보호창(50)은 휴대단말기의 두께가 박형화 되어가는 추세에 따라 점차 두께가 얇아지고 있어 보호창(50) 정압시험에 의해 가해지는 힘이 보호창(50)에 의해 그대로 액정모듈로 전달되어 보호창(50) 정압시험에 따른 강도 개선에도 한계가 있는 문제점이 있게 된다. In addition, the protective window 50 of the mobile terminal is gradually thinner as the thickness of the portable terminal becomes thinner, and the force applied by the protective window 50 positive pressure test is directly applied by the protective window 50. Is delivered to the module has a problem that there is a limit to the strength improvement according to the protective window 50 static pressure test.

본 발명은 액정모듈의 전체적인 강도를 향상시켜 COG 정압시험 및 보호창 정합시험시 강도가 저하되는 단점을 극복한다.The present invention improves the overall strength of the liquid crystal module to overcome the disadvantage that the strength is reduced during the COG static pressure test and protective window matching test.

본 발명의 액정모듈 이중 샤시구조는, 액정패널, 일면이 상기 액정패널의 후면에 지지 고정되는 이너샤시, 상기 액정패널에 빛을 조사하는 백라이트 유닛이 내부에 실장되며, 상기 이너샤시 타측에 고정되는 몰드프레임 및 상기 이너샤시와 몰드프레임의 타측을 감싸도록 설치되는 아우터샤시를 포함한다.In the liquid crystal module dual chassis structure of the present invention, the liquid crystal panel, an inner chassis having one surface supported and fixed to the rear surface of the liquid crystal panel, a backlight unit for irradiating light to the liquid crystal panel is mounted therein, and fixed to the other side of the inner chassis. It includes a mold frame and the outer chassis installed to surround the inner chassis and the other side of the mold frame.

이하, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 본 발명을 용이하게 실시할 수 있을 정도로 본 발명의 바람직한 실시 예를 첨부된 도면을 참조하여 상세하게 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings such that those skilled in the art may easily implement the present invention.

도 3은 본 발명의 일 실시예에 따른 액정모듈의 구성을 나타낸 정면도이며, 도 4는 3의 결합구조를 나타낸 단면도이다.3 is a front view showing the configuration of a liquid crystal module according to an embodiment of the present invention, Figure 4 is a cross-sectional view showing a coupling structure of 3.

도 3 내지 도 4의 도시된 바와 같이 본 발명에 따른 액정모듈(A)은 액정패널(100)과, 일면이 상기 액정패널(100)의 후면에 지지 고정되는 이너샤시(200)와, 상기 액정패널(100)에 빛을 조사하는 백라이트 유닛(310)이 내부에 실장되며, 상기 이너샤시(200) 타측에 고정되는 몰드프레임(300) 및 상기 이너샤시(200)에 몰드프레임(300)을 고정시키기 위해 상기 이너샤시(200)와 몰드프레임(300)의 타측을 감싸도록 설치되는 아우터샤시(400)로 구분 형성된다.3 to 4, the liquid crystal module A according to the present invention includes a liquid crystal panel 100, an inner chassis 200 having one surface supported and fixed to the rear surface of the liquid crystal panel 100, and the liquid crystal. The backlight unit 310 for irradiating light to the panel 100 is mounted therein, and the mold frame 300 fixed to the inner side of the inner chassis 200 and the mold frame 300 are fixed to the inner chassis 200. In order to form the inner chassis 200 and the outer chassis 400 which is installed to surround the other side of the mold frame 300 is formed.

액정패널(100)은 두장의 유리기판(예를 들면, 상부 유리기판과 하부 유리기판)의 사이에 매트릭스 형태로 배열되어진 액정셀들과 이들 액정셀들에 공급되는 신호를 각각 절환하기 위한 스위치 소자들(즉, 박막트랜지스터(TFT) 어레이) 및 상,하 유리판재 사이에는 제어신호 및 데이터 신호를 전달하기 위한 연성회로기판(Flexible Printed Circuit Board:FPCB)이 삽입되어 구성된다.The liquid crystal panel 100 includes liquid crystal cells arranged in a matrix form between two glass substrates (for example, an upper glass substrate and a lower glass substrate) and a switch element for switching signals supplied to the liquid crystal cells, respectively. The flexible printed circuit board (FPCB) for transmitting a control signal and a data signal is inserted between the thin film transistor (TFT) array and the upper and lower glass plates.

또한, 액정패널(100)의 두장의 유리기판의 상,하부에 위치하여 백라이트유닛(200) 광빔의 편광특성을 변환시키는 편광판(110)을 포함하여 구성된다.In addition, the liquid crystal panel 100 includes a polarizing plate 110 positioned above and below the two glass substrates to convert polarization characteristics of the light beam of the backlight unit 200.

한편, 편광판(110)은 액정패널(100)의 상,하부에 부착되어 여러 방향으로 진 동하면서 입사되는 빛을 한쪽 방향으로만 진동하는 빛(즉, 편광)이 되도록 하는 기능을 가지며, 액정패널(100)의 상,하부면 각각에 접착부에 의해 부착된다. On the other hand, the polarizing plate 110 is attached to the upper and lower portions of the liquid crystal panel 100 and has a function to make the light incident to vibrate in one direction while vibrating in various directions (that is, polarized light), the liquid crystal panel It is attached to each of the upper and lower surfaces of the (100) by the adhesive portion.

또한, 편광판(110)은 폴리비닐알코올 등으로 만들어진 편광막이 양면에 붙은 형태로 형성된다.In addition, the polarizing plate 110 is formed in a form in which a polarizing film made of polyvinyl alcohol or the like adheres to both surfaces.

이너샤시(200)는 가장자리 부위가 상기 액정패널(100)과 멀어지는 방향으로 연장되는 박스형태의 구조로 일면에는 액정패널의 후면을 지지하도록 구성되며, 타측으로 백라이트 유닛(310)이 포함된 몰드프레임(300)이 수용될 수 있도록 구성되고, 상기 액정패널(100)과의 고정은 양면테이프에 의해서 가능하다.The inner sash 200 has a box-shaped structure in which an edge portion extends away from the liquid crystal panel 100, and is configured to support the rear side of the liquid crystal panel on one side thereof, and the mold frame including the backlight unit 310 on the other side. 300 is configured to be accommodated, and fixing with the liquid crystal panel 100 is possible by double-sided tape.

또한, 이너샤시(200)의 액정패널(100)과 부착되는 면으로 백라이트 유닛(310)의 빛이 상기 액정패널(100)에 직접 조사되도록 개구부(210)가 형성된다.In addition, an opening 210 is formed to be directly attached to the liquid crystal panel 100 of the inner chassis 200 so that the light of the backlight unit 310 is directly irradiated onto the liquid crystal panel 100.

한편, 이너샤시(200)는 종래의 액정모듈과 다르게 강도 개선을 위해 추가되는 구성으로, 충분한 휨강성을 가지며 외부충격은 일부 흡수할 수 있는 재질로 형성된다.On the other hand, the inner chassis 200 is a configuration that is added to improve the strength unlike the conventional liquid crystal module, has a sufficient bending rigidity and is formed of a material that can absorb some external impact.

몰드프레임(300)은 액정패널(100)이 자체 발광력이 없기 때문에 디스플레이를 위한 광원으로서 액정패널(100)에 빛을 조사하는 백라이트 유닛(310)이 포함되며, 상기 백라이트 유닛(310)을 조립 고정하여 이너샤시(200)의 개방된 타면에 양면테이프를 이용하여 설치된다.The mold frame 300 includes a backlight unit 310 that irradiates light to the liquid crystal panel 100 as a light source for the display because the liquid crystal panel 100 does not have a self-luminous power, and assembles the backlight unit 310. It is fixed and installed on the other open surface of the inner sash 200 using double-sided tape.

아우터샤시(400)는 가장자리 부위가 상기 액정패널(100)을 지나도록 연장되는 박스형태의 구조로 일면은 완전 개방되어 이너샤시(200)를 수용할 수 있도록 구성되고, 타면에는 일부분만이 개방되거나 막혀지는 형태를 갖는다.The outer chassis 400 is a box-shaped structure in which an edge portion extends through the liquid crystal panel 100 so that one surface is completely open to accommodate the inner chassis 200, and only a part of the outer chassis 400 is opened. It has a form that is blocked.

또한, 아우터샤시(400)에는 본 발명의 액정패널(100)을 보호할 수 있도록 형성되는 소정의 보강부(410)가 형성된다.In addition, the outer chassis 400 is provided with a predetermined reinforcing portion 410 formed to protect the liquid crystal panel 100 of the present invention.

즉, 액정모듈(A)은 휴대단말기(M)에 장착시 액정패널(100)과 액정패널(100)을 보호하는 보호창(500)이 직접 접촉되지 않도록 액정패널(100)이 아우터샤시(400) 내에 수용되어 아우터샤시(400)만이 보호창(500)과 접촉되도록 설치된다.That is, when the liquid crystal module A is mounted on the portable terminal M, the liquid crystal panel 100 is not connected to the outer chassis 400 so that the liquid crystal panel 100 and the protective window 500 protecting the liquid crystal panel 100 do not directly contact each other. It is accommodated in the) is installed so that only the outer chassis 400 is in contact with the protective window (500).

그러나, 액정패널(100)이 보호창(500)과 직접 접촉되지는 않지만, 최근 휴대단말기의 두께가 박형화 되어가는 추세에 따라 보호창(500)의 두께는 얇아져 처짐이 발생하기 때문에 보호창(500)에 작용하는 가압력은 그대로 액정패널(100)로 전달될 수밖에 없다.However, although the liquid crystal panel 100 is not in direct contact with the protective window 500, the protective window 500 is thinner and thinner due to the recent trend of thinning of the portable terminal. The pressing force acting on) is inevitably transmitted to the liquid crystal panel 100.

이때, 상기 아우터샤시(400)는 가장자리 끝단에 액정패널(100)과 평행하게 연장되는 보강부(410)를 형성되어 외력의 작용시 상기 보강부(410)가 액정패널(100)로 작용하는 힘을 지탱하고 분산시켜 액정패널(100)을 보호할 수 있게 되는 것이다.In this case, the outer chassis 400 has a reinforcement portion 410 extending in parallel with the liquid crystal panel 100 at the edge end thereof, and thus, when the external force is applied, the reinforcement portion 410 acts as the liquid crystal panel 100. By supporting and dispersing the liquid crystal panel 100 can be protected.

여기서, 보강부(410)는 몰드프레임(300)의 후방에서 이너샤시(200)의 일부를 감싸도록 설치되는 아우터샤시(400)의 끝단에 형성되는 것이 바람직하다.Here, the reinforcing part 410 is preferably formed at the end of the outer chassis 400 which is installed to surround a portion of the inner chassis 200 in the rear of the mold frame 300.

즉, 아우터샤시(400)는 일정두께를 갖는 도전성 재질을 갖는 철판으로 몰드프레임(300)의 후방에서 이너샤시(200)를 감싸도록 설치되어 액정모듈(A) 전체의 강도를 증대시킴은 물론, ESD성능까지 개선시키기 위한 목적으로 설치된다.That is, the outer chassis 400 is installed to surround the inner sash 200 at the rear of the mold frame 300 by an iron plate having a conductive material having a predetermined thickness to increase the strength of the entire liquid crystal module A, as well as It is installed for the purpose of improving ESD performance.

이때, 아우터샤시(400)의 끝단 일부를 이너샤시(200)의 전방, 즉 액정패널(100)의 상, 하부까지 연장 및 절곡하여 소정의 보강부(410)가 형성되도록 함으 로써, 액정패널(100)을 보호할 수 있게 된다.At this time, by extending and bending a portion of the end of the outer chassis 400 to the front of the inner chassis 200, that is, the upper and lower portions of the liquid crystal panel 100, a predetermined reinforcement portion 410 is formed, thereby forming a liquid crystal panel ( 100) can be protected.

따라서, 이와 같이 보강부(51)가 구비된 액정모듈(A)이 단말기에 장착되어 정압시험 또는 보호창(70)에 외력이 작용하는 경우, 상기 보강부(51)가 액정패널(100)에 작용하는 힘을 지탱하고 분산시킬 수 있게 되기 때문에 단말기의 슬림화에 따른 단말기의 취약한 구조를 개선할 뿐만 아니라, 이너샤시(200) 및 아우터샤시(400)의 이중구조에 의해 횡강성 및 강도를 향상시킬 수 있게 된다.Therefore, when the liquid crystal module A having the reinforcement part 51 is mounted on the terminal and an external force acts on the positive pressure test or the protective window 70, the reinforcement part 51 is applied to the liquid crystal panel 100. Since it is possible to support and disperse the working force, not only the weak structure of the terminal according to the slimming of the terminal can be improved, but also the lateral stiffness and strength can be improved by the dual structure of the inner chassis 200 and the outer chassis 400. It becomes possible.

한편, 본 발명에서는 상기 보강부(410)가 몰드프레임(300)의 후방에 설치된 아우터샤시(400)의 끝단 일부가 절곡되어 형성된 것에 대하여 설명하고 있으나, 이에 한정되는 것은 아니며 상기 보강부(410)가 형성되는 위치에 별도의 기구물이 형성될 수도 있음은 물론, 상기 보강부(410)의 특정한 구성에 한정되는 것은 아니다.On the other hand, in the present invention has been described that the reinforcement portion 410 is formed by bending a portion of the end of the outer chassis 400 installed in the rear of the mold frame 300, but is not limited to this, the reinforcement portion 410 Of course, a separate mechanism may be formed at the position where it is formed, of course, it is not limited to the specific configuration of the reinforcement portion 410.

이상, 본 발명을 바람직한 실시 예를 사용하여 상세히 설명하였으나, 본 발명의 범위는 특정 실시 예에 한정되는 것은 아니며, 첨부된 특허 청구범위에 의하여 해석되어야 할 것이다. 또한, 이 기술분야에서 통상의 지식을 습득한 자라면, 본 발명의 범위에서 벗어나지 않으면서도 많은 수정과 변형이 가능함을 이해하여야 할 것이다.As mentioned above, although this invention was demonstrated in detail using the preferable embodiment, the scope of the present invention is not limited to a specific embodiment and should be interpreted by the attached claim. In addition, those skilled in the art should understand that many modifications and variations are possible without departing from the scope of the present invention.

본 발명에 따른 액정모듈의 이중 샤시구조에 의하면, 이너샤시와 아우터샤시에 의한 이중구조에 의하여 휨강성이 증가하여 낙하 신뢰성에서보다 낳은 결과를 얻을 수 있는 효과를 제공한다.According to the dual chassis structure of the liquid crystal module according to the present invention, the flexural rigidity is increased by the dual structure by the inner chassis and the outer chassis, thereby providing an effect that results in better results in drop reliability.

또한, 보강부가 보조창 방향에 작용하는 힘을 지탱하면서 분산시킬 수 있기 때문에 COG 정압시험 또는 보조창 정압시험 또는 외력의 작용시 액정패널을 보호할 수 있게 됨은 물론, 액정모듈이 장착된 단말기의 슬림화에 따른 취약한 폰 구조상의 문제를 해결할 수 있게 되는 등의 효과를 제공한다.In addition, since the reinforcing part can be dispersed while supporting the force acting in the direction of the auxiliary window, it is possible to protect the liquid crystal panel during the COG positive pressure test or the auxiliary window positive pressure test or the action of external force, as well as the slimming of the terminal equipped with the liquid crystal module. It can be used to solve vulnerable phone structure problems.
