일반적으로 널리 사용되고 있는 표시장치들 중의 하나인 CRT(Cathode Ray Tube)는 TV를 비롯해서 계측기기, 정보 단말기기 등의 모니터에 주로 이용되고 있으나, CRT 자체의 무게와 크기로 인해 전자 제품의 소형화, 경량화의 요구에 적극 대응할 수 없었다.CRT (Cathode Ray Tube), one of the widely used display devices, is mainly used for monitors such as TVs, measuring devices, information terminal devices, etc., but due to the weight and size of the CRT itself, the miniaturization and weight reduction of electronic products Could not respond actively to the demands of.
이러한, CRT를 대체하기 위해 소형, 경량화 및 저소비전력의 장점을 갖고 있는 액정표시장치가 활발하게 개발되어 왔고, 최근에는 평판 표시장치로서의 역할을 충분히 수행할 수 있을 정도로 개발되어 액정표시장치의 수요는 계속적으로 증가되고 있는 실정이다.In order to replace the CRT, a liquid crystal display device having advantages of small size, light weight, and low power consumption has been actively developed, and recently, the liquid crystal display device has been developed enough to perform a role as a flat panel display device. The situation is increasing continuously.
이와 같은 액정표시장치의 대부분은 외부에서 들어오는 광의 양을 조절하여 화면에 표시하는 수광성 소자이기 때문에 엘시디(LCD) 패널에 광을 조사하기 위한 별도의 장치, 즉 백라이트 어셈블리가 반드시 필요하다.Since most of the liquid crystal display devices are light-receiving elements that adjust the amount of light from the outside and display them on the screen, a separate device, that is, a backlight assembly, for irradiating light to the LCD panel is necessary.
백라이트 어셈블리는 크게 수납공간이 형성된 몰드프레임(mold frame)과, 수납공간의 일측에 설치되어 빛을 발산하는 램프 어셈블리(lamp assembly)와, 수납공간의 기저면에 설치되어 빛을 반사하는 반사판과, 반사판의 상부에 설치되어 빛을 안내하는 도광판과, 도광판의 상부에 설치되어 빛을 확산하고 집광하는 시트들과, 몰드프레임과 결합되어 엘시디 패널을 지지하는 탑샤시로 구성된다.The backlight assembly includes a mold frame in which a storage space is largely formed, a lamp assembly installed at one side of the storage space to emit light, a reflective plate installed at the base surface of the storage space to reflect light, and a reflecting plate.

시트들(24)을 구성하는 확산시트(30), 프리즘시트들(32), 보호시트(34)의 일측 모서리 영역에는 각각의 시트들(24)로부터 외측방향으로 연장되어 돌출부들(36)이 형성되고, 보호시트(34)와 프리즘시트(32)에 형성된 돌출부들(36) 사이에는 보호시트(34)와 프리즘 시트(32)를 고정하는 양면접착테이프(38)가 위치한다.In one corner area of the diffusion sheet 30, the prism sheets 32, and the protective sheet 34 constituting the sheets 24, the protrusions 36 extend outwardly from the respective sheets 24. The double-sided adhesive tape 38 fixing the protective sheet 34 and the prism sheet 32 is positioned between the protective sheet 34 and the protrusions 36 formed on the prism sheet 32.
이러한 돌출부(36)의 역할은 액티브 영역(40)의 가장자리에 양면접착테이프(38)가 근접되어 광휘도에 영향을 끼치는 것을 방지할 수 있도록 하기 위해서 액티브 영역(40)의 가장자리로부터 양면접착테이프(38)를 최대한 이격시키는데 있다.The role of the protrusion 36 is that the double-sided adhesive tape 38 is close to the edge of the active region 40 so that the double-sided adhesive tape (from the edge of the active region 40 can be prevented from affecting the brightness). 38) as far as possible.
또한, 양면접착테이프(38)를 돌출부(36) 영역에 한정하여 부착하는 것은 각기 다른 시트들(24)의 열팽창률에 대응할 수 있도록 하기 위함이다.In addition, attaching the double-sided adhesive tape 38 to the protrusion 36 region is limited so as to correspond to the thermal expansion rates of the different sheets 24.
이와 같이 시트들 사이에 양면접착테이프를 개재하여 시트들을 고정시킴으로써 시트들의 유동이 방지되고, 이로 인해 시트들의 표면에 긁힘이 발생되지 않으며, 시트들이 한쪽으로 쏠리거나 몰드프레임의 윗면으로 시트들이 올라오는 것이 방지된다.In this way, the sheets are fixed by interposing the two-sided adhesive tapes between the sheets, thereby preventing the sheets from flowing, thereby preventing scratches on the surfaces of the sheets, and the sheets are pulled to one side or the sheets are raised to the upper side of the mold frame. Is prevented.
도 3에서 미설명 부호 42는 엘시디 패널(26)의 길이방향 일측면에 설치되어 엘시디 패널(26)의 게이트선(도시 안됨)을 구동시키는 게이트 PCB이고, 44는 엘시디 패널(26)과 게이트 PCB(42)를 전기적으로 연결시켜 주는 테이프 캐리어 패키지이며, 46은 게이트 PCB(42)에 실장된 소자들을 수납하기 위한 수납홈이다.In FIG. 3, reference numeral 42 is a gate PCB installed on one longitudinal side of the LCD panel 26 to drive a gate line (not shown) of the LCD panel 26, and 44 denotes an LCD panel 26 and a gate PCB. A tape carrier package for electrically connecting the 42 is 46, and 46 is a receiving groove for accommodating elements mounted on the gate PCB 42. As shown in FIG.
이상에서 살펴본 바와 같은 본 발명은 시트들 사이 중에서 적어도 어느 하나의 사이에 양면접착테이프를 개재하여 시트들을 고정시킴으로써, 시트들의 유동이 방지되고, 이로 인해 시트들의 표면에 긁힘이 발생되던 것이 방지되며, 시트들이 한쪽으로 쏠리거나 몰드 프레임의 윗면으로 돌출되는 것이 방지되어 제품의 신뢰성이 향상되는 효과가 있다.The present invention as described above by fixing the sheets through the double-sided adhesive tape between at least one of the sheets, the flow of the sheets is prevented, thereby preventing the scratches on the surface of the sheets, Sheets are prevented from being pushed to one side or protruding from the upper surface of the mold frame, thereby improving the reliability of the product.
