Description

엘시디 모듈{LCD module}LCD module {LCD module}

본 발명은 엘시디 모듈에 관한 것으로. 더욱 상세하게는 몰드 프레임에 시트류움방지부를 설치하여 시트류들의 움 현상을 방지할 수 있도록 한 엘시디 모듈에 관한 것이다.The present invention relates to an LCD module. More particularly, the present invention relates to an LCD module, which can prevent a weeping of sheets by installing a sheet preventing layer on a mold frame.

일반적으로 현대사회가 정보 사회화되어감에 따라 정보표시장치의 하나인 LCD 장치의 중요성이 점차 증가되고 있다. 지금까지 가장 널리 사용되고 있는 CRT(cathode ray tube)는 성능이나 가격적인 측면에서 많은 장점을 갖고 있지만 소형화 또는 휴대성 측면에서 많은 단점을 갖고 있다. 반면에 LCD 장치는 가격측면에서 다소 비싸지만 경량화, 박형화 및 저전력소비화 등의 장점을 갖고 있어 CRT의 단점을 극복할 수 있는 대체수단으로 주목되고 있다.In general, as the modern society becomes information socialized, the importance of the LCD device, which is one of the information display devices, is gradually increasing. Cathode ray tube (CRT), which is widely used so far, has many advantages in terms of performance and cost, but has many disadvantages in terms of miniaturization or portability. On the other hand, although LCD devices are somewhat expensive in terms of price, they are attracting attention as an alternative means of overcoming the disadvantages of CRT because they have advantages such as light weight, thickness, and low power consumption.

특히 최근에는 과학 기술이 발달됨에 따라 이러한 LCD 장치가 모니터링용으로 개발되면서 LCD 장치의 디스플레이 화면 크기가 커지는 추세이다.In particular, as the development of science and technology, such LCD devices are developed for monitoring, the display screen size of LCD devices is increasing.

이러한 대형화 추세에 있는 LCD 장치를 구성하는 구성 요소 가운데 LCD 모듈(이하 엘시디 모듈로 칭함)의 구성을 도 1을 참조하여 살펴보면 다음과 같다.Referring to FIG. 1, the configuration of an LCD module (hereinafter referred to as an LCD module) among the components constituting the LCD device having such an enlargement trend is as follows.

도시된 바와 같이, 몰드 프레임(10)의 상부에 광을 확산 및 집광하는 시트류들(12)이 수납되고, 시트류들(12)의 상부에 광을 가이드하는 도광판(14)이 위치하며, 광을 가이드하는 도광판(14)의 상부에는 바텀샷시(도시되지 않음)가 설치된다.As shown in the drawing, sheets 12 for diffusing and condensing light are accommodated on the upper part of the mold frame 10, and a light guide plate 14 for guiding light is positioned on the sheets 12. A bottom sash (not shown) is provided above the light guide plate 14 for guiding the light.

몰드 프레임(10)의 하부면에는 데이터를 디스플레이하는 엘시디(LCD) 패널(16)이 설치되고, 몰드 프레임(10)의 측면과 엘시디 패널(16)의 하부면의 가장자리를 커버하는 탑샷시(도시되지 않음)가 몰드 프레임(10)에 설치된다.An LCD panel 16 for displaying data is provided on the lower surface of the mold frame 10, and a top sash (shown) covering the side of the mold frame 10 and the edge of the lower surface of the LCD panel 16 is illustrated. (Not shown) is installed in the mold frame 10.

그러나 시트류들과 엘시디 패널 사이에 위치하는 몰드 프레임으로 인해 시트류들과 엘시디 패널 사이에 일정 공간이 형성되고, 신뢰성 테스트 및 외부 환경의 온도 변화 발생시, 일정 공간에서 시트류들의 움 현상이 발생되는 문제점이 있었다.However, due to the mold frame located between the sheets and the LCD panel, a certain space is formed between the sheets and the LCD panel, and when the reliability test and the temperature change of the external environment occur, the sheets are moved in a certain space. There was a problem.

따라서, 본 발명의 목적은 시트류들의 움 현상이 발생되지 않도록 하는데 있다.Therefore, it is an object of the present invention to prevent the occurrence of withdrawal of sheets.

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.

이와 같은 목적을 달성하기 위해서 본 발명은 시트류들의 타면에 시트류움방지부를 설치하여 도광판과 더불어 시트류들의 전후면을 압착할 수 있도록 한다.In order to achieve the above object, the present invention provides a sheet flow prevention part on the other surface of the sheets, so as to compress the front and rear surfaces of the sheets together with the light guide plate.

이때, 시트류움방지부는 시트류들로부터의 광을 투과하는 광투과판으로 시트류들의 타면 전체와 대응되는 것이 바람직하며, 이 광투과판으로는 아크릴판과 글래스판 등이 사용될 수 있다.In this case, the sheet flow prevention part is a light transmitting plate that transmits light from the sheets, and preferably corresponds to the whole of the other surface of the sheets. The light transmitting plate may be an acrylic plate, a glass plate, or the like.

한편, 도광판과 시트류들과 시트류움방지부를 홀더를 사용하여 일체로 고정하여 엘시디 모듈의 조립을 보다 용이하게 할 수 있다.Meanwhile, the LGP module may be more easily assembled by fixing the light guide plate, the sheets, and the sheet flow prevention unit integrally using a holder.

이하 첨부된 도 2를 참조하여 본 발명의 실시예를 보다 상세히 살펴보면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

도시된 바와 같이 몰드 프레임(20)의 상부면 내부에 시트류움방지부인 광투과판(22)이 수납되고, 보호시트(24)와 광을 집광하는 프리즘시트(26)와 광을 확산하는 확산시트(28)를 차례로 구비한 시트류들(30)이 광투과판(22)상에 놓여지며, 시트류들(30)의 상부에는 광을 가이드하는 도광판(32)이 설치되며, 도광판(32)의 상부면에 바텀샷시(도시되지 않음)가 설치된다.As shown in the upper surface of the mold frame 20, the light transmitting plate 22, which is a sheet preventing member, is accommodated, the prism sheet 26 for condensing the light with the protective sheet 24, and the diffusion sheet for diffusing the light. Sheets 30, which are sequentially provided with 28, are placed on the light transmitting plate 22, and a light guide plate 32 for guiding light is provided on the sheet 30, and the light guide plate 32 is provided. Bottom sash (not shown) is installed on the upper surface of the.

몰드 프레임(20)의 하부면에는 데이터를 디스플레이하는 엘시디(LCD) 패널(34)이 설치되고, 몰드 프레임(20)의 측면과 엘시디 패널(34)의 하부면의 가장자리를 커버하는 탑샷시(도시되지 않음)가 몰드 프레임(20)에 설치된다.An LCD panel 34 for displaying data is provided on the lower surface of the mold frame 20, and a top sash (shown) covering the side of the mold frame 20 and the edges of the lower surface of the LCD panel 34 is illustrated. (Not shown) is installed in the mold frame 20.

여기서, 본 발명에 따른 광투과판에 대해 보다 자세히 살펴보면, 광투과판(22)은 시트류들(30)로부터의 광이 관통되도록 소정 두께를 갖는 아크릴판 또는 글래스판으로 이루어진다.Here, looking at the light transmitting plate according to the present invention in more detail, the light transmitting plate 22 is made of an acrylic plate or glass plate having a predetermined thickness so that the light from the sheets 30 through.

이때, 광투과판(22)은 광투과판(22) 자체에 휘는 현상이 발생되지 않도록 일정 두께를 갖는 것이 바람직하다.At this time, the light transmitting plate 22 preferably has a predetermined thickness so that the bending phenomenon does not occur in the light transmitting plate 22 itself.

이렇게 광투과판을 몰드 프레임에 설치하여 도광판과 더불어 시트류들의 전후면 전체를 밀착시킴으로써 시트류들의 움 현상이 발생될 공간이 제거되어 시트류들의 움이 발생되지 않는다.In this way, the light transmitting plate is installed in the mold frame to closely contact the entire front and rear surfaces of the sheets together with the light guide plate, thereby eliminating the space of the sheets in which the sheets of the sheets are generated.

한편, 도 3은 엘시디 모듈의 조립을 보다 용이하게 할 수 있도록 하기 위한 것으로, 상기 실시예에서 언급한 부분과 동일한 부분에 대한 상세한 설명은 생략하기로 한다.On the other hand, Figure 3 is intended to facilitate the assembly of the LCD module, the detailed description of the same parts as those mentioned in the embodiment will be omitted.

도시된 바와 같이, 적층된 도광판(34)과 시트류들(36)과 광투과판(38)을 일체로 고정하기 위해서 홀더(40)가 도광판(34)과 시트류들(36)과 광투과판(38)의 가장자리 영역을 일체로 압착한다.As shown, in order to integrally fix the laminated light guide plate 34 and the sheets 36 and the light transmissive plate 38, the holder 40 is provided with the light guide plate 34 and the sheets 36 and the light transmission. The edge region of the plate 38 is integrally compressed.

이렇게 홀더에 의해 일체로 고정된 도광판과 시트류들과 광투과판들은 한 묶음으로 세트화된 상태로 몰드 프레임에 설치되기 때문에 엘시디 모듈의 조립이 보다 용이해진다.Since the light guide plate, sheets and light transmitting plates integrally fixed by the holder are installed in the mold frame in a set state in a bundle, the assembly of the LCD module becomes easier.

이상에서 살펴본 바와 같이 본 발명은 광투과판을 시트류들의 타면에 설치하여 도광판과 더불어 시트류들의 전후면 전체를 압착함으로써 시트류들에서 움 현상이 발생되는 것을 방지하여 제품의 신뢰성을 향상시킬 수 있고, 도광판과 시트류들과 광투과판을 홀더로 일체로 고정하여 엘시디 모듈의 조립을 보다 용이하게 함으로써 제품의 생산성이 향상되는 효과가 있다.As described above, the present invention can improve the reliability of the product by preventing light from occurring in the sheets by compressing the entire front and rear surfaces of the sheets together with the light guide plate by installing the light transmitting plate on the other surface of the sheets. In addition, the light guide plate, the sheets and the light transmitting plate are integrally fixed to the holder to facilitate the assembly of the LCD module, thereby improving the productivity of the product.
