본 발명은 액정표시에 관한 것으로, 특히 인쇄회로기판의 미동을 방지하기 위한 액정표시장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a liquid crystal display, and more particularly, to a liquid crystal display device for preventing fine motion of a printed circuit board.

액정표시장치(Liquid Crystal Display : LCD)는 액정 패널에 매트릭스 형태로 배열된 액정셀들 각각이 비디오 신호에 따라 광투과율을 조절함으로써 화상을 표시하게 된다.A liquid crystal display (LCD) displays an image by adjusting light transmittance of each of the liquid crystal cells arranged in a matrix form on a liquid crystal panel according to a video signal.

이러한 액정표시장치는 액정표시패널과, 액정표시패널과 전기적으로 연결되며 액정표시장치를 구동시키기 위해 구동소자가 실장된 인쇄회로기판(Printed Circuit board)과, 액정표시패널에 빛을 제공하는 백라이트(back light)유닛과, 백라이트 유닛을 수납하는 몰드프레임으로 구성된다.

인쇄회로기판은 몰드프레임의 상부에 형성된 역 "L"자 형태의 걸림턱에 의해 몰드프레임에 고정된다. 즉, 테이프 캐리어 패키지가 부착된 인쇄회로기판은 슬라이드 방식으로 걸림턱 내로 삽입된다. 그러나, 걸림턱 내부로 인쇄회로기판을 삽입할 경우 가해지는 힘이 테이프 캐리어 패키지에 전달되어 테이프 캐리어 패키지와 패널이 분리되는 문제점이 있다. 또한, 여러 개의 걸림턱에 인쇄회로기판을 끼워넣어야 함으로 인쇄회로기판이 삽입되지 않는 걸림턱이 발생되는 경우 여러번의 삽입공정을 거쳐야하는 문제점이 있다.The printed circuit board is fixed to the mold frame by a locking jaw of an inverted "L" shape formed on the mold frame. That is, the printed circuit board to which the tape carrier package is attached is inserted into the locking step in a slide manner. However, there is a problem in that the force applied when the printed circuit board is inserted into the latching jaw is transmitted to the tape carrier package to separate the tape carrier package and the panel. In addition, there is a problem that the insertion step of the printed circuit board has to go through a number of insertion processes when the printed circuit board is not inserted into the printed circuit board to be inserted into the multiple engaging jaw.

한편, 걸림턱이 인쇄회로기판을 제대로 고정시키지 못하는 경우 임의로 접착 테이프를 통해 인쇄회로기판을 몰드프레임에 고정한다. 이 경우 접착 테이프 부착 공정이 부가적으로 필요하므로 공정시간이 증가됨과 아울러 접착 테이프로 인한 비 용이 상승되는 문제점이 있다.On the other hand, when the locking jaw does not properly secure the printed circuit board, the printed circuit board is fixed to the mold frame through an adhesive tape. In this case, since the adhesive tape attaching process is additionally required, there is a problem that the process time is increased and the cost due to the adhesive tape is increased.

A plurality of driving chips 21 are mounted on the printed circuit board 20. The printed circuit board 20 is mounted on the lower surface of the mold frame 40, and the through hole 24 is formed at a position corresponding to the protrusion 42 formed on the mold frame 40. The through hole 24 preferably uses a jig hole for fixing the printed circuit board 20 in the process of attaching the printed circuit board 20 and the tape carrier package 22.

몰드프레임(40)에는 화상을 구현하는 액정패널과, 액정패널에 광을 공급하는 백라이트 유닛(10)이 수납된다.The mold frame 40 houses a liquid crystal panel that implements an image and a backlight unit 10 that supplies light to the liquid crystal panel.

여기서, 표시패널은 박막 트랜지스터(Thin Film Transistor : TFT)기판, TFT 기판과 서로 대향하는 컬러필터 기판과, TFT 기판과 컬러 필터 기판의 사이에 주입된 액정층을 포함한다.Here, the display panel includes a thin film transistor (TFT) substrate, a color filter substrate facing the TFT substrate, and a liquid crystal layer injected between the TFT substrate and the color filter substrate.

TFT 기판은 스위칭 소자인 TFT가 매트릭스 형태로 형성되어 액정층을 구동 하기 위한 화소 전극에 신호 전압을 인가한다.In a TFT substrate, a TFT, which is a switching element, is formed in a matrix to apply a signal voltage to a pixel electrode for driving a liquid crystal layer.

컬러필터 기판은 광에 의해 소정의 색으로 발현되는 컬러 필터가 형성된 기판이다.The color filter substrate is a substrate on which a color filter expressed in a predetermined color by light is formed.

백라이트 유닛(10)은 백라이트 유닛은 빛을 생성하는 램프와, 램프로부터 생성된 빛을 평면광원으로 변환하여 액정표시패널쪽으로 출사시키는 도광판과, 도광판으로부터 새어나온 빛을 액정표시패널쪽으로 반사시키는 반사막과, 도광판으로부터 출사된 빛을 확산시켜 빛의 휘도를 향샹시키는 확산 시트와, 도광판으로부터 나오는 빛을 집광시켜 직진성 휘도를 향상시키는 프리즘시트와, 확산시트와 프리즘시트들의 손상을 방지하기 위한 보호막을 포함한다. The backlight unit 10 may include a lamp that generates light, a light guide plate that converts light generated from the lamp into a planar light source, and emits the light toward the liquid crystal display panel, and a reflective film that reflects light emitted from the light guide plate toward the liquid crystal display panel. And a diffusion sheet for diffusing the light emitted from the light guide plate to improve the brightness of the light, a prism sheet for condensing the light emitted from the light guide plate to improve the linear brightness, and a protective film for preventing damage to the diffusion sheet and the prism sheets. .

이러한 몰드프레임(40)은 도 2 및 도 3에 도시된 바와 같이 사각틀로 형성되며, 인쇄회로기판(20)이 안착되는 안착면(41)을 가진다. 이 안착면(41) 상에는 인쇄회로기판(20)의 관통홀(24)에 삽입되는 돌출부(42)가 형성된다. The mold frame 40 is formed in a rectangular frame as shown in FIGS. 2 and 3, and has a seating surface 41 on which the printed circuit board 20 is mounted. On the seating surface 41, a protrusion 42 inserted into the through hole 24 of the printed circuit board 20 is formed.

여기서, 인쇄회로기판(20)의 고정된 위치에 형성된 관통홀(24)이 몰드프레임(40)의 안착면(41)을 벗어날 경우 도 3에 도시된 바와 같이 안착면(41)으로부터 신장된 연장면(43) 상에 돌출부(42)가 형성된다.Here, when the through-hole 24 formed in the fixed position of the printed circuit board 20 is out of the seating surface 41 of the mold frame 40, as shown in FIG. 3, the extension extending from the seating surface 41 A protrusion 42 is formed on the face 43.

도 4에 도시된 돌출부(42)는 몸통부분(B)과 머리부분(H)으로 구분된다. 이 돌출부(42)의 몸통부분(B)은 인쇄회로기판(42)과 같은 두께를 가지며, 머리부분(H1)의 두께(d1)는 인쇄회로기판(20) 상에 형성된 구동칩(21)의 두께(d2)보다 작은 두께를 가진다. 또한, 머리부분(H)은 몸통부분(B)쪽으로 갈수록 폭이 넓어지는 형태이며, 몸통부분(B)보다 선폭이 크므로 돌출부(42)에 인쇄회로기판(20)은 유동되 지않고 몰드프레임(40)과 고정된다. The protrusion 42 shown in FIG. 4 is divided into a body portion B and a head portion H. The trunk portion B of the protruding portion 42 has the same thickness as the printed circuit board 42, and the thickness d1 of the head portion H1 is the width of the driving chip 21 formed on the printed circuit board 20. It has a thickness smaller than the thickness d2. In addition, the head portion (H) is a shape that is wider toward the body portion (B) toward the wider, since the line width is larger than the body portion (B), the printed circuit board 20 does not flow to the protrusion 42, the mold frame It is fixed with 40.

여기서, 머리부분(H)은 탄성력을 가진 반원 또는 반타원인 기둥형태로 형성되거나 그 기둥형태가 적어도 두 개로 분할되어 형성된다. 이때, 머리부분(H)은 반원 또는 반타원 형태의 경사면을 따라 관통홀(24)로 용이하게 삽입되며 잘 빠지지 않는다. Here, the head portion (H) is formed in the form of a column which is a semi-circle or semi-ellipse with elastic force or is formed by dividing the column form into at least two. At this time, the head portion (H) is easily inserted into the through hole 24 along the inclined surface of the semi-circle or semi-ellipse, and does not fall well.

Accordingly, the separation of the tape carrier package and the panel can be prevented and the contact process between the printed circuit board and the mold frame using a separate adhesive tape is unnecessary, thereby simplifying the process.

또한, 본 발명에 따른 액정표시장치는 지그홀을 관통홀로 이용함으로써 관통홀을 형성하기 위한 별도의 공정이 불필요하므로 재료비를 절감할 수 있다. In addition, the liquid crystal display according to the present invention can use the jig hole as a through hole, so that a separate process for forming the through hole is unnecessary, thereby reducing the material cost.

또한, 서로 다른 인치의 액정표시장치이라도 인쇄회로기판과 테이프 캐리어 패키지 부착 공정시 이용되는 인쇄회로기판 지그가 동일하면 지그홀, 즉 관통홀의 크기 및 간격이 동일하므로 같은 금형을 이용하여 돌출부를 형성할 수 있다.Also, even if the LCDs of different inches have the same printed circuit board jig used in the process of attaching the printed circuit board and the tape carrier package, the jig holes, i.e., through holes have the same size and spacing, so that protrusions may be formed using the same mold.
