Description
본 발명은 엘씨디(LCD: Liquid Crystal Display Device, 이하, "LCD"라 칭함)의 백라이트 장치에 관한 것으로, 더욱 상세하게는 노이즈 발생을 방지한 엘씨디의 백라이트 장치에 관한 것이다.The present invention relates to a backlight device of an LCD (LCD: Liquid Crystal Display Device, hereinafter referred to as "LCD"), and more particularly to a backlight device of an LCD which prevents noise generation.
최근 LCD 모듈에서 램프 어셈블리의 역할과 기능은 갈수록 중요한 과제로 대두되고 있는 데, 이는 램프 어셈블리의 구조에 따라서 LCD 모듈의 크기, 중량 등이 크게 달라지기 때문이다.In recent years, the role and function of the lamp assembly in the LCD module is becoming an increasingly important task, because the size, weight, etc. of the LCD module varies greatly depending on the structure of the lamp assembly.
이와 같은 이유로 인해 최근들어 램프 어셈블리의 교체 방식 또한 중요한 과제로 대두되고 있으며, 이러한 램프 어셈블리 교체 방식 중의 하나로 몰드 프레임의 백면(Back side)에서 도광판 일측으로 램프 어셈블리를 끼워 넣는 방식이 광범위하게 사용되고 있다. 이러한 경우, 통상, 램프 어셈블리를 지지하고 보호하기 위한 목적으로 몰드 프레임의 백면에는 백커버가 채결되는 것이 일반적이다.For this reason, a lamp assembly replacement method has recently emerged as an important problem. As one of the lamp assembly replacement methods, a lamp assembly is inserted into one side of the light guide plate from the back side of the mold frame. In this case, it is usually common for the back cover to be joined to the back surface of the mold frame for the purpose of supporting and protecting the lamp assembly.
도 1 및 도 2에 도시된 바와 같이, 몰드 프레임(3)은 램프 어셈블리(5), 도광판(7), 시트류(8), LCD 패널(미도시) 등을 지지하고 있으며, 이러한 몰드 프레임은 탑 샤시(4)에 의해 감싸진다.As shown in FIGS. 1 and 2, the mold frame 3 supports the lamp assembly 5, the light guide plate 7, the sheets 8, an LCD panel (not shown), and the like. It is wrapped by the top chassis 4.
이와 함께, 몰드 프레임(3)의 백면에는 램프 어셈블리(5)를 몰드 프레임(3) 내부에 용이하게 삽입하기 위한 삽입 슬릿(9a)이 형성된다.In addition, an insertion slit 9a for easily inserting the lamp assembly 5 into the mold frame 3 is formed on the back surface of the mold frame 3.
이때, 삽입 슬릿(9a)을 통해 램프 어셈블리(5)가 몰드 프레임(3)의 내부에 삽입되면 백커버(1)는 몰드 프레임(3)의 백면에 부착됨으로써, 삽입 슬릿(9a)을 폐쇄시킨다. 이에 따라, 램프 어셈블리(5)는 외부의 충격으로부터 안전하게 보호된다.At this time, when the lamp assembly 5 is inserted into the mold frame 3 through the insertion slit 9a, the back cover 1 is attached to the back surface of the mold frame 3, thereby closing the insertion slit 9a. . Thus, the lamp assembly 5 is safely protected from external shocks.
이러한 경우, 백커버(1)의 상부면에 형성된 로킹 후크(2)는 몰드 프레임(3)의 돌출턱(9)에 걸리게 되며, 돌출턱(9)은 로킹 후크(2)의 로킹 홀(2a)에 양호하게 삽입됨으로써, 백커버(1)를 몰드 프레임(3)의 백면에 견고히 고정시킨다.In this case, the locking hook 2 formed on the upper surface of the back cover 1 is caught by the protruding jaw 9 of the mold frame 3, and the protruding jaw 9 is the locking hole 2a of the locking hook 2. ), The back cover 1 is firmly fixed to the back surface of the mold frame 3.
또한, 램프 어셈블리(5)를 구성하고 있는 램프 반사판(5a)의 반사율을 증대시키기 위해서 절연성 램프 반사판(5a)의 내측면에 반사율이 매우 높은 은 코팅 쉬트(5b)를 부착하는 방법 또한 개발된 바 있다. 이때, 미설명 도면부호 2는 로킹 후크이고, 2a는 로킹 홀이다.Further, in order to increase the reflectance of the lamp reflector 5a constituting the lamp assembly 5, a method of attaching a silver coating sheet 5b having a very high reflectance to the inner surface of the insulated lamp reflector 5a has also been developed. have. In this case, reference numeral 2 is a locking hook, and 2a is a locking hole.
그러나, LCD 백라이트의 광원으로 사용되는 램프는 주로 냉음극형광램프가 사용되고 냉음극형광램프를 구동하기 위해서는 약 600~700 볼트의 고압 교류를 필요로 한다. 이때 고압 교류는 도선이 접촉되지 않아도 근접한 도전성 재질에 전류를 흐르게 하는 변위 전류(displacement current)를 유발하여 램프에만 흘러야할 전류는 램프 반사판으로 누설되어 노이즈 발생과 소비전력 증대를 유발시키는 문제점이 있다.However, a lamp used as a light source of an LCD backlight is mainly used a cold cathode fluorescent lamp and requires a high voltage alternating current of about 600 ~ 700 volts to drive the cold cathode fluorescent lamp. At this time, the high-voltage AC causes a displacement current that causes a current to flow to the adjacent conductive material even when the wire is not in contact, so that the current to flow only in the lamp leaks to the lamp reflector, causing noise and increasing power consumption.
이에 본 발명의 기술적 과제는 이러한 종래의 문제점을 해결하기 위한 것으로, 본 발명의 목적은 변위 전류에 의하여 누설되는 누설전류를 도전성 백 커버를 통하여 대지에 접지시킴으로써 노이즈 발생을 방지한 엘씨디의 백라이트 장치를 제공하는 것이다.Therefore, the technical problem of the present invention is to solve such a conventional problem, and an object of the present invention is to prevent the occurrence of noise by grounding the leakage current leaked by the displacement current to the ground through the conductive back cover to prevent the backlight device of the LCD To provide.
상기한 본 발명의 목적을 달성하기 위한 일 실시예에 따른 엘씨디의 백라이트 장치는 램프 어셈블리, 도광판, 광학 시트류, 몰드 프레임, 탑 샤시 및 백커버를 포함한다. 상기 램프 어셈블리는 광을 발생하는 램프와, 상기 램프의 일부를 감싸고, 내측면에 도전성 반사판이 형성된다. 상기 도광판은 측면이 상기 램프 어셈블리와 마주보도록 배치되어, 상기 광을 가이드하여 상부로 출사시킨다. 상기 광학 시트류는 상기 도광판의 상부에 배치되어, 상기 출사된 광의 광학 특성을 향상시킨다. 상기 몰드 프레임은 액정 표시채널을 수용하고, 상기 램프 어셈블리가 위치되어 있는 소정면에 상기 램프 어셈블리를 착탈시키기 위한 삽입 슬릿이 형성된다. 상기 탑 샤시는 상기 몰드 프레임을 감싸면서, 상기 램프 어셈블리가 형성된 쪽으로 상기 몰드 프레임의 측면을 따라 연장된다. 상기 백커버는 상기 몰드 프레임과 결합되어 상기 삽입 슬릿을 차단하고, 도전성 나사에 의하여 상기 도전성 반사판과 체결되어 상기 도전성 반사판과 공통 접지된다. 선택적으로, 상기 도전성 반사판은 상기 램프 반사판의 단부로부터 연장되어 상기 램프 반사판의 외측으로 절곡될 수 있다.LCD backlight device according to an embodiment for achieving the above object of the present invention includes a lamp assembly, a light guide plate, an optical sheet, a mold frame, a top chassis and a back cover. The lamp assembly may include a lamp for generating light, a portion of the lamp, and a conductive reflector on an inner surface thereof. The light guide plate is disposed such that a side surface thereof faces the lamp assembly, and guides the light to be emitted upward. The optical sheets are disposed on the light guide plate to improve optical characteristics of the emitted light. The mold frame accommodates a liquid crystal display channel, and an insertion slit is formed on a predetermined surface on which the lamp assembly is located to attach and detach the lamp assembly. The top chassis surrounds the mold frame and extends along the side of the mold frame toward the lamp assembly. The back cover is coupled to the mold frame to block the insertion slit, and is coupled to the conductive reflector by a conductive screw to be commonly grounded with the conductive reflector. Optionally, the conductive reflector may extend from an end of the lamp reflector and bend outward of the lamp reflector.
이하, 본 발명에 의한 엘씨디의 백라이트 장치를 첨부된 도면을 참조하여 설명하면 다음과 같다.Hereinafter, a backlight device of an LCD according to the present invention will be described with reference to the accompanying drawings.
본 발명에 의한 엘씨디의 백라이트 장치의 몰드 프레임(3)은 첨부된 도 3, 도 4에 도시된 바와 같이 램프 어셈블리(5), 도광판(7), 시트류(8), LCD 패널(미도시) 등을 지지하고 있으며, 이러한 몰드 프레임(3)은 탑 샤시(4)에 의해 감싸진다.The mold frame 3 of the backlight unit of the LCD according to the present invention is a lamp assembly 5, a light guide plate 7, sheets 8, LCD panel (not shown) as shown in Figs. The mold frame 3 is surrounded by the top chassis 4.
램프 어셈블리(5)는 다시 램프 반사판(5a)과 냉음극형광램프(5c)로 구성된다.The lamp assembly 5 is further composed of a lamp reflector 5a and a cold cathode fluorescent lamp 5c.
램프 반사판(5a)의 내측 즉, 냉음극형광램프(5c)과 대향하는 면에는 광반사율을 증대시키기 위한 도전성 은 코팅 쉬트(5b)가 별도로 형성된다.On the inner side of the lamp reflecting plate 5a, that is, the surface facing the cold cathode fluorescent lamp 5c, a conductive silver coating sheet 5b for increasing the light reflectivity is separately formed.
이때, 은 코팅 쉬트(5b)는 첨부된 도 5에 도시된 바와 같이 단부가 램프 반사판(5a)로부터 소정 길이 연장되어 돌출된 후 램프 반사판(5a)을 감싸는 형태로 램프 반사판(5a)의 내측으로부터 외측으로 절곡된다.At this time, the silver coating sheet 5b is formed from the inner side of the lamp reflecting plate 5a in such a manner as to enclose the lamp reflecting plate 5a after the end extends a predetermined length from the lamp reflecting plate 5a and protrudes, as shown in FIG. 5. It is bent outward.
이와 같이 은 코팅 쉬트(5b)가 절곡된 상태에서 램프 반사판(5a)를 고정시키기 위해서 양면에 형성된 은 코팅 쉬트(5b)와 절연성 램프 반사판(5a)에는 관통공(5d)이 형성되고, 관통공(5d)에 대응하는 도전성 백커버(1)에도 암나사부가 형성된 관통공(1a)이 형성된다.As described above, through holes 5d are formed in the silver coating sheet 5b and the insulating lamp reflecting plate 5a formed on both surfaces to fix the lamp reflecting plate 5a while the silver coating sheet 5b is bent. The through-hole 1a in which the female screw part was formed is also formed in the electroconductive back cover 1 corresponding to 5d.
이 램프 반사판(5a)의 관통공(5d)과 도전성 백커버(1)의 관통공(1a)에는 은 코팅 쉬트(5b)로 누설되는 누설 전류가 대지에 접지되도록 도전성 나사(10)가 나사체결되어 은 코팅 쉬트(5b)로 누설되어 노이즈를 발생시키던 누설 전류는 도전성 백커버(1)에 의하여 접지되어 노이즈의 발생이 방지된다.The conductive screw 10 is screwed into the through hole 5d of the lamp reflector 5a and the through hole 1a of the conductive back cover 1 so that the leakage current leaked to the silver coating sheet 5b is grounded to the ground. The leakage current, which leaks into the silver coating sheet 5b and generates noise, is grounded by the conductive back cover 1 to prevent generation of noise.
이상에서 살펴본 바와 같이 램프 반사판의 내측에 형성된 은 코팅 쉬트를 램프 반사판으로부터 연장 돌출시킨 상태에서 은 코팅 쉬트를 절곡하여 램프 반사판이 감싸여지도록 하고 램프 반사판 - 은 코팅 쉬트 - 백커버가 도전성 나사에 의하여 공통 접지되도록 하여 상기 은 코팅 쉬트로 누설되던 전류에 의한 노이즈 발생을 방지하는 효과가 있다.As described above, the silver coating sheet formed inside the lamp reflector is extended from the lamp reflector to bend the silver coating sheet so that the lamp reflector is wrapped, and the lamp reflector-silver coating sheet-back cover is formed by the conductive screw. It is possible to prevent the generation of noise due to the current leaked into the silver coating sheet by making a common ground.
