Description

엘시디 모듈LCD module

본 발명은 엘시디 모듈에 관한 것으로, 더욱 상세하게는 도광판이 램프 어셈블리 방향으로 이동하는 것을 차단할 수 있도록 한 엘시디 모듈에 관한 것이다.The present invention relates to an LCD module, and more particularly to an LCD module that can prevent the light guide plate from moving in the direction of the lamp assembly.

일반적으로 액정표시장치는 자체 광원이 없는 수동 표시장치로써 램프, 도광판 및 시트류 등의 백라이트 어셈블리를 필요로 하고, 이는 액정표시장치의 디스플레이 성능에 있어서 중요한 역할을 하며 경량박형화의 특성을 가지고 있다.In general, a liquid crystal display device is a passive display device having no own light source and requires a backlight assembly such as a lamp, a light guide plate, sheets, etc., which plays an important role in the display performance of the liquid crystal display device and has a characteristic of light weight and thinning.

그러나 이러한 경량박형화의 최근 추세는 도광판 및 시트류를 몰드 프레임에 고정하기 위한 여유 공간의 부족을 초래하였다. 이로 인해 몰드 프레임에 고정되어 있는 도광판 및 시트류 등이 약한 충격에도 쉽게 유동하여 액정표시장치의 품질이 저하되었다.However, the recent trend of light weight thinning has caused a lack of free space for fixing the light guide plate and sheet to the mold frame. As a result, the light guide plate and the sheets fixed to the mold frame are easily flowed even under a weak impact, thereby degrading the quality of the liquid crystal display.

이러한 도광판 및 시트류의 유동을 방지할 수 있도록 하기 위해 엘시디 모듈에는 다음과 같은 구조가 채용되었다.In order to prevent the flow of the light guide plate and sheet, the LCD module adopts the following structure.

도 1에 도시된 바와 같이, 반사시트(10)와 확산시트(12)와 프리즘시트(14)와 보호시트(16)를 구비한 시트류(18) 및 도광판(20)의 양측면에 소정 형상을 갖는 돌출부(22)가 형성되고, 시트류(18) 및 도광판(20)을 수용하면서 지지하는 몰드 프레임(24)의 내측면에 돌출부(22)와 대향되어 결합하는 결합홈(26)이 형성된다.As shown in FIG. 1, a predetermined shape is formed on both sides of the sheet 18 and the light guide plate 20 having the reflective sheet 10, the diffusion sheet 12, the prism sheet 14, and the protective sheet 16. Protruding portion 22 is formed, and a coupling groove 26 is formed on the inner surface of the mold frame 24 for holding and supporting the sheets 18 and the light guide plate 20 so as to be opposed to the protrusion 22. .

도광판(20)의 일측면에는 도광판(20)으로 광을 공급하는 램프 어셈블리(28)가 설치된다.One side of the light guide plate 20 is provided with a lamp assembly 28 for supplying light to the light guide plate 20.

이와 같이 도광판(20) 및 시트류(18)의 돌출부(22)가 몰드 프레임(24)의 결합홈(26)에 끼워져 몰드프레임(24)내에 설치됨으로써 엘시디 모듈에 외부의 충격이 가해질 경우 도광판(20) 및 시트류(18)는 돌출부(22)가 결합홈(26)에 걸려 유동되지 않았다. 미설명 부호 29는 탑샤시이다.As such, the light guide plate 20 and the protrusions 22 of the sheets 18 are inserted into the coupling grooves 26 of the mold frame 24 and installed in the mold frame 24, so that when an external impact is applied to the LCD module, the light guide plate ( 20) and the sheet 18, the projection 22 is caught in the engaging groove 26 did not flow. Reference numeral 29 is a top chassis.

그러나, 이와 같이 양측면에 돌출부가 형성된 도광판은 크기가 유효화면표시영역(active area ; 점선표시된 부분)보다 충분히 크지 않으면 돌출부나 결합홈에서 빛고임 현상이나 암부가 생겨서 제품의 품질 저하의 원인이 되었다.However, the light guide plate having protrusions on both side surfaces of the light guide plate having the protrusions on both sides is not large enough than the active area (dotted line), resulting in light-glow phenomenon or dark spots in the protrusions or the coupling grooves, resulting in deterioration of product quality.

따라서, 본 발명의 목적은 빛고임 현상 및 암부의 발생을 제거하여 제품의 품질을 향상시킬 수 있도록 하는데 있다.Therefore, it is an object of the present invention to improve the quality of the product by eliminating the phenomenon of light shine and dark areas.

본 발명의 다른 목적은 다음의 상세한 설명 및 첨부된 도면으로부터 보다 명확해질 것이다.Other objects of the present invention will become more apparent from the following detailed description and the accompanying drawings.

도 2는 본 발명의 기술에 따른 실시예에 의한 백커버가 제거된 엘시디 모듈을 나타낸 저면도.Figure 2 is a bottom view showing the LCD module with the back cover removed according to an embodiment of the present invention.

도 3은 도 2의 Ⅲ-Ⅲ를 나타낸 단면도.3 is a cross-sectional view illustrating III-III of FIG. 2.

이와 같은 목적을 달성하기 위해서 본 발명은 도광판과 램프 어셈블리 사이에 차단부를 형성하여 도광판이 램프 어셈블리 방향으로 유동하는 것을 차단할 수 있도록 한다.In order to achieve the above object, the present invention forms a blocking portion between the light guide plate and the lamp assembly to prevent the light guide plate from flowing in the direction of the lamp assembly.

이때, 차단부는 도광판의 측면과 대응되어 설치되어 몰드 프레임에 연장 설치될 수 있다.In this case, the blocking part may be installed to correspond to the side of the light guide plate and may be extended to the mold frame.

이하 첨부된 도면을 참조하여 본 발명의 기술에 따른 실시예에 의한 엘시디 모듈을 보다 상세히 살펴보면 다음과 같다.Hereinafter, an LCD module according to an embodiment of the present disclosure will be described in detail with reference to the accompanying drawings.

도 2 및 도 3에 도시된 바와 같이 도광판(30) 및 시트류(32)의 양측면에 형성된 돌출부와 몰드 프레임(34)의 내측면에 형성된 돌출부와 결합되는 결합홈이 제거된 것을 확인할 수 있다.As shown in FIGS. 2 and 3, the protrusions formed on both side surfaces of the light guide plate 30 and the sheets 32 and the coupling grooves coupled to the protrusions formed on the inner surface of the mold frame 34 are removed.

여기서, 도 3을 살펴보면, 단면 형상이 'ㄱ'자 형상인 몰드 프레임(34)이 위치하고, 몰드 프레임(34)의 상부면에는 데이터를 디스플레이하는 엘시디 패널(36)이 설치되며, 엘시디 패널(34)의 일측에는 엘시디 패널(34)과 전기적으로 연결된 엘시디 패널용 구동부(38)가 설치된다.Here, referring to FIG. 3, a mold frame 34 having a cross-sectional shape of a '-' shape is positioned, and an LCD panel 36 for displaying data is installed on an upper surface of the mold frame 34, and the LCD panel 34 is installed. One side of the) is installed the LCD panel drive unit 38 is electrically connected to the LCD panel 34.

몰드 프레임(34)의 하부면에는 광을 가이드하는 도광판(30)이 설치되며, 도광판(30)과 엘시디 패널(34) 사이에는 도광판(30)으로부터의 광을 확산시키는 확산시트(40), 확산시트(40)의 광을 집광시키는 프리즘시트(42) 및 이러한 시트를 보호하는 보호시트(44)로 이루어진 시트류(32)가 설치된다.A light guide plate 30 for guiding light is provided on the lower surface of the mold frame 34, and a diffusion sheet 40 for diffusing light from the light guide plate 30 between the light guide plate 30 and the LCD panel 34, and diffusion. Sheets 32 composed of a prism sheet 42 for condensing light of the sheet 40 and a protective sheet 44 for protecting the sheet are provided.

도광판(30)의 하부에는 광을 반사하는 반사시트(46)가 설치된다.The lower portion of the light guide plate 30 is provided with a reflective sheet 46 for reflecting light.

도광판(30)의 일측면에는 램프(48)와 램프(48)를 감싸는 램프커버(50)를 구비한 램프 어셈블리(52)가 설치된다.One side of the light guide plate 30 is provided with a lamp assembly 52 having a lamp 48 and a lamp cover 50 surrounding the lamp 48.

본 발명에 따르면, 도광판(30)의 측면과 램프 어셈블리(52) 사이에는 몰드 프레임(34)의 하부면으로부터 소정 길이 연장 돌출되어 형성된 리브와 같은 차단부(54)가 위치한다.According to the present invention, between the side of the light guide plate 30 and the lamp assembly 52, a blocking portion 54, such as a rib, is formed to extend and protrude a predetermined length from the lower surface of the mold frame 34.

이때, 차단부(54)는 도광판(30)의 측면과 대응되게 형성되어 도광판(30)이 유동하는 것을 안정적으로 차단할 수 있도록 한다.In this case, the blocking unit 54 is formed to correspond to the side of the light guide plate 30 to stably block the flow of the light guide plate 30.

미설명 부호 56은 탑샤시이다.Reference numeral 56 is a top chassis.

이와 같이 도광판과 램프 어셈블리 사이에 몰드 프레임에 일체로 형성된 리드가 위치함으로써 외부 충격으로 인해 도광판이 램프 어셈블리 방향으로 유동하는 것을 차단부를 통해 차단할 수 있어 램프의 파손을 방지할 수 있게 된다.As such, the lead integrally formed in the mold frame is disposed between the light guide plate and the lamp assembly, thereby preventing the light guide plate from flowing in the direction of the lamp assembly due to external impact through the blocking unit, thereby preventing damage to the lamp.

이상에서 살펴본 바와 같이, 본 발명은 도광판과 램프 어셈블리 사이에 차단부를 형성하여 도광판이 램프 어셈블리 방향으로 유동하는 것을 차단함으로써 도광판에 의해 램프 어셈블리의 램프가 파손되는 것이 방지되어 제품의 신뢰성이 향상되는 효과가 있다.As described above, the present invention forms a blocking portion between the light guide plate and the lamp assembly to block the light guide plate from flowing in the direction of the lamp assembly, thereby preventing the lamp of the lamp assembly from being damaged by the light guide plate, thereby improving product reliability. There is.
