* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings
15 : 냉음극 형광등 확산판 15a : 경사면15: cold cathode fluorescent lamp diffusion plate 15a: inclined surface
19 : 탭 아이씨19: Tap IC
본 고안은 액정표시장치에 관한 것으로, 특히 확산판과 탭 아이씨가 겹치는 부분의 구조를 변경하여 전체적으로 조립 두께를 박형화하도록 한 액정표시장치에 관한 것이다.The present invention relates to a liquid crystal display device, and more particularly, to a liquid crystal display device in which the structure of the overlapping portion of the diffusion plate and the tab IC is changed to reduce the overall assembly thickness.
종래 노트북 퍼스널 컴퓨터 등에 채용되고 있는 액정표시장치는 금속제 지지 프레임(support frame), 액정표시소자(LCD)용 유리판, 탭 아이씨(TAB IC : tape automatic bonding IC) 및 필름형 인쇄회로기판, 그리고 냉음극 형광등(CFL) 백라이트가 필수적으로 구비되어 있으며, 액정표시소자 모듈의 골격을 유지하기 위해 상기한 지지 프레임외에도 이를 지지하기 위한 몰딩(molding)물로서 아크릴 니트릴 부타디엔 스티렌 공중합수지(ABS;) 또는 풀리 카보네이트(Poly Cabonate)의 재료가 사용되고 있다.Conventionally, liquid crystal display devices employed in notebook personal computers and the like include metal support frames, glass plates for LCDs, tape automatic bonding ICs (TAB ICs) and film printed circuit boards, and cold cathodes. Fluorescent lamp (CFL) backlight is essentially provided, and in order to maintain the structure of the liquid crystal display module, acrylonitrile butadiene styrene copolymer resin (ABS;) or a pulley carbonate as a molding for supporting it in addition to the support frame described above. (Poly Cabonate) material is used.
제1도는 종래 노트북 PC에 이용되고 있는 액정표시장치의 일실시형태를 보인 단면도로서, 도면에서 1은 금속제 지지 프레임을 보인 것이고, 2, 3은 상, 하부 그래스(액정표시소자 패널)을 보인 것이며, 4는 냉음극 형광등 확산 필름, 5는 냉음극 형광등 확산판(아크릴재), 6은 냉음극 형광등 반사 필름을 각각 보인 것으로 몰딩물(7)위에 적층되어 있으며, 냉음극 형광등 반사 필름(6)의 하부에는 탭 아이씨(9)가 삽입되고 플레시블 인쇄회로기판(8)이 연결되어 있다.FIG. 1 is a cross-sectional view showing an embodiment of a liquid crystal display device used in a conventional notebook PC, in which 1 shows a metal support frame, and 2 and 3 show an upper and a lower glass (liquid crystal display panel). 4 is a cold cathode fluorescent light diffusing film, 5 is a cold cathode fluorescent light diffusing plate (acrylic material), 6 is a cold cathode fluorescent light reflecting film is laminated on the molding (7), cold cathode fluorescent light reflecting film (6) At the bottom of the tab IC 9 is inserted and the flexible printed circuit board 8 is connected.
이와같이 종래의 액정표시장치는 플렉시블 인쇄회로기판(flexible PCB)(8)과 탭 아이씨(9)가 냉음극 형광등 확산판(5)과 겹쳐져 있기 때문에 전체 두께에 영향을 주게 되는 것이었다.As described above, the conventional liquid crystal display device affects the overall thickness because the flexible PCB 8 and the tab IC 9 overlap with the cold cathode fluorescent lamp diffusion plate 5.
따라서, 이러한 구조적인 문제를 해결함으로써 전체 두께를 감소시키기 위해 여러방향에서 그 해결책이 모색되고 있다.Therefore, solutions have been sought in several directions to reduce the overall thickness by solving these structural problems.
이러한 해결책의 하나로서 일본 공개실용신안공보 평4-50823호와 같은 액정표시장치가 안출된 바 있다.As one of such solutions, a liquid crystal display device such as Japanese Patent Application Laid-open No. Hei 4-50823 has been devised.
그러나 이러한 구조에서는 드라이버 아이씨를 회로기판에 부착한 것으로서 두께를 얇게 할 수 있으나 회로기판을 도장판의 저면으로 깊숙히 진입시킬 수 없기 때문에 그 외곽에 배치되는 드라이버 회로블록등에 의하여 액정표시장치의 평면적인 크기가 커지게 되는 문제점이 있는 것이었다.However, in such a structure, the driver IC is attached to the circuit board, so that the thickness can be reduced. However, since the circuit board cannot be deeply inserted into the bottom of the paint board, the flat size of the liquid crystal display device by the driver circuit block disposed at the outer part thereof. There was a problem that becomes large.
본 고안의 목적은 냉음극 형광등과 같은 광원을 하나 또는 복수개 채용하고 있는 액정표시장치에서 확산판과 아이시 회로부분의 구조적인 문제점을 해소하여 조립 두께를 보다 얇게 할 수 있음과 아울러 평면적인 크기를 축소할 수 있도록 한 액정표시장치를 제공하려는 것이다.The object of the present invention is to solve the structural problems of the diffuser plate and the IC circuit part in a liquid crystal display device employing one or more light sources such as a cold cathode fluorescent lamp, thereby making the assembly thickness thinner and providing a flat size. It is to provide a liquid crystal display device that can be reduced.
이하 본 고안에 의한 액정표시장치를 첨부한 도면에 의하여 상세히 설명한다.Hereinafter, the liquid crystal display according to the present invention will be described in detail with reference to the accompanying drawings.
제2도는 본 고안의 구성을 보인 단면도이고, 제3도는 측면도이며, 제4도는 요부 단면도로서, 이에 도시한 바와같이, 본 고안의 액정표시장치는 금속제 지지 프레임(11), 액정표시소자 패널(12), (13), 냉음극 형광등 확산필름(14), 냉음극 형광등 확산판(15), 냉음극 형광등 반사층(16)이 도포되어 몰딩물(17)위에 결합되어 있으며, 냉음극 형광등 확산판(15)의 하부에는 탭 아이씨(19)가 삽입되고, 플레시블 인쇄회로기판(18)으로 연결되어 있다.2 is a cross-sectional view showing the configuration of the present invention, FIG. 3 is a side view, and FIG. 4 is a cross-sectional view of the main part. 12), (13), cold cathode fluorescent light diffusion film 14, cold cathode fluorescent light diffusion plate 15, cold cathode fluorescent light reflecting layer 16 is applied and bonded on the molding 17, cold cathode fluorescent light diffusion plate A tab IC 19 is inserted into the lower part of the part 15 and is connected to the flexible printed circuit board 18.
그리고, 상기 냉음극 형광등 확산판(15)은 도시한 바와같이 모서리부를 경사지게 하여 탭 아이씨(19)를 냉음극 형광등 확산판(15)의 경사면(15a)에 밀착시킨 구조로 되어 있으며, 상기 냉음극 형광등 반사층(16)은 기존의 반사 필름의 재질을 이용하게 되면 필름의 재질이 딱딱하므로 필름의 텐션으로 인해 제4a도와 같이 경사면(15a)에 완전히 밀착되지 않고, 이에따라 냉음극 형광등 확산판(15) 전면에서 광 확산 불균일 현상이 나타날 우려가 있기 때문에 제4b도와 같이 반사필름 대신 냉음극 형광등 확산판(15)의 경사면(15a)에 반사물질을 도포하여 냉음극 형광등 반사층(16)을 형성하였다.The cold cathode fluorescent lamp diffusion plate 15 has a structure in which the tab IC 19 is brought into close contact with the inclined surface 15a of the cold cathode fluorescent lamp diffusion plate 15 by inclining the corner portion as shown in the drawing. When the fluorescent material reflecting layer 16 uses the material of the existing reflective film, the material of the film is hard, and thus the film is not completely adhered to the inclined surface 15a as shown in FIG. 4a due to the tension of the film. Since there is a possibility that light diffusion nonuniformity may occur from the entire surface, as shown in FIG. 4B, a reflective material is applied to the inclined surface 15a of the cold cathode fluorescent lamp diffusion plate 15 instead of the reflective film to form the cold cathode fluorescent lamp reflection layer 16.
또한, 냉음극 형광등(20)의 빛이 가까운 곳 "a"에서 먼곳 "b"로 갈수록 약해짐으로 "b"로 갈수록 빛을 난반사시켜 "a"부분에서는 빛이 조금 반사되고 "b"부분에서는 많이 반사되어 전체적으로 거의 균일하게 반사시킬 수 있도록 냉음극 형광등 확산판(15)의 밑면에 난반사 표면처리를 하였다.In addition, since the light of the cold cathode fluorescent lamp 20 becomes weaker from the near "a" to the far "b", the light is diffusely reflected toward the "b" so that the light is slightly reflected in the "a" part and in the "b" part. The diffuse reflection surface treatment was applied to the bottom surface of the cold cathode fluorescent lamp diffuser plate 15 so as to be reflected a lot and reflected almost uniformly.
즉, 냉음극 형광등 확산판(15)의 경사면(15a)에 난반사 표면처리를 함으로써 경사에 따른 불 균일을 해소하고 광 균일도를 높이도록 개선, 보상하였다.That is, by performing diffuse reflection surface treatment on the inclined surface 15a of the cold cathode fluorescent lamp diffusion plate 15, the unevenness caused by the inclination is solved and the light uniformity is improved and compensated.
이상에서 설명한 바와같은 본 고안은 최근 퍼스널 컴퓨터 사용자로부터 급격한 호평을 받고 있는 노트북형 퍼스널 컴퓨터의 액정표시장치를 종래 보다 얇게 제작할 수 있으므로 노트북형 퍼스널 컴퓨터를 소형화하는데 기여하여 제품의 경쟁력을 향상하는 이점이 있다.As described above, the present invention can manufacture a liquid crystal display device of a notebook personal computer, which has been rapidly received by a personal computer user in recent years, thus making it possible to make the notebook personal computer smaller, thereby improving the competitiveness of the product. have.
이러한 본 고안은 노트북형 퍼스널 컴퓨터용 액정표시장치 이외에도 탭 아이씨를 사용하는 각종 액정표시장치에 유리하게 이용할 수 있다.The present invention can be advantageously used for various liquid crystal display devices using tab ICs in addition to the liquid crystal display devices for notebook personal computers.
