여기서는 액정표시장치에서의 액정패널과 일체된 터치패널에 관하여 주로 설명하기로 한다.Herein, the touch panel integrated with the liquid crystal panel in the liquid crystal display will mainly be described.
도 1은 종래기술에 따른 터치패널 일체형 액정표시모듈의 단면을 나타내는 도면이다.1 is a view showing a cross section of a touch panel integrated liquid crystal display module according to the prior art.
도 1을 참조하면, 터치패널 일체형 액정표시모듈은 액정패널을 구성하는 상부 및 하부기판(26,24)과, 램프(16)와, 램프(16)의 주변에 형성되어 램프를 보호함과 아울러 광을 일정 방향으로 입사시키는 램프 하우징(18)과, 램프(16)로부터 입사된 광을 평면광원으로 변환하여 상기 액정패널 쪽으로 진행하게 하는 도광판/확산판(20)과, 도광판(20)에서 방출되는 휘선 및 빛샘을 방지하기 위한 리플렉터(22)와, 도광판/확산판(20)을 고정하기 위한 서포트 메인(14)과, 가시광선을 직선편광으로 바꿔주기 위한 편광판(28)과, 상기 편광판(28) 상에 적층되어 형성된 터치패널(30)과, 서포트 메인(14)의 측면과 저면을 감싸는 커버보텀(12)과, 커버보텀(12)과 서포트메인(14)의 측면을 감싸고 상기 서포트 메인의 상부 가장자리를 감싸는 탑케이스(22)를 구비한다.Referring to FIG. 1, the touch panel integrated liquid crystal display module is formed around the upper and lower substrates 26 and 24, the lamp 16, and the lamp 16 constituting the liquid crystal panel to protect the lamp. A lamp housing 18 for injecting light in a predetermined direction, a light guide plate / diffusion plate 20 for converting light incident from the lamp 16 into a planar light source, and proceeding toward the liquid crystal panel, and emission from the light guide plate 20 A reflector 22 for preventing bright lines and light leakage, a support main 14 for fixing the light guide plate / diffusion plate 20, a polarizing plate 28 for converting visible light into linearly polarized light, and the polarizing plate ( 28, the cover panel 12 formed on the support panel 14, the cover bottom 12 surrounding the side and the bottom of the support main 14, and the cover bottom 12 and the side of the support main 14, and the support main It has a top case 22 surrounding the upper edge of the.
이러한, 터치패널 일체형 액정표시모듈의 실장순서를 상세히 설명하면, 먼저 제1 순서는 액정패널과 램프(16)를 일체화하는 서포트 메인(14)을 실장하는 것이며, 제2 순서는 액정패널에 평면광을 방출하기 위한 도광판/확산판(12)을 실장하는 것이며, 제3 순서는 도광판(12)이 광을 방출할 때 발생하는 휘선 및 빛샘을 방지하기 위한 리플렉터(22)를 실장하는 것이고, 제4 순서는 액정표시모듈과 백라이트(12)을 고정하기 위해 커버보텀(12)에 실장하는 것이며, 제5 순서는 액정표시모듈 상에 터치패널(30)을 접착제를 이용하여 부착시키는 것이며, 마지막으로 액정표시모듈과 터치패널(30)의 유효화면 이외의 부분을 가려줌과 아울러 상기 액정표시모듈과 램프(16)를 고정하기 위한 탑케이스(10)로 실장함으로써 터치패널 일체형 액정표시모듈의 조립이 완성된다. 또한 커버보텀(12)과 탑케이스(10)는 스크류(도시하지 않음)을 이용하여 체결되어진다.When the mounting procedure of the touch panel integrated liquid crystal display module is described in detail, first, the first procedure is to mount the support main 14 integrating the liquid crystal panel and the lamp 16, and the second procedure is to planar light on the liquid crystal panel. The light guide plate / diffusion plate 12 for emitting light is mounted, and the third order is to mount the reflector 22 to prevent bright lines and light leakage that occur when the light guide plate 12 emits light. The procedure is to mount the cover bottom 12 to fix the liquid crystal display module and the backlight 12, the fifth procedure is to attach the touch panel 30 on the liquid crystal display module using an adhesive, and finally the liquid crystal The assembly of the touch panel integrated liquid crystal display module is completed by covering the portions other than the effective screen of the display module and the touch panel 30 and mounting them as a top case 10 for fixing the liquid crystal display module and the lamp 16. do. In addition, the cover bottom 12 and the top case 10 are fastened by using a screw (not shown).
터치패널(30)은 필름-필름 방식으로 액정표시모듈의 상부기판(26)에 직접 부착하는 방법이다. 이로써 터치패널과 액정표시모듈 사이에 발생하는 불필요한 공기층을 제거해 투과 및 반사에 있어 시인성을 향상시키게 된다.The touch panel 30 is a method of directly attaching to the upper substrate 26 of the liquid crystal display module by a film-film method. As a result, unnecessary air layers generated between the touch panel and the liquid crystal display module are removed, thereby improving visibility in transmission and reflection.
그러나, 저항막 방식 터치패널은 좌표 인식에 필요한 X, Y축 전계를 위해 은(Ag)으로 형성된 전극층이 있으며, 터치패널의 상/하부기판에 부착된 투명전극층은 전극층 높이만큼 갭(Gap)이 존재한다. 이때 갭은 전극층이 형성된 에지(Edge)부로 갈수록 스타일러스 펜 또는 손가락에 의해 눌려질 때 상부 투명전극층에 크랙이 발생하는 문제점이 있게 된다. 이로 인해, 저항막 방식 터치패널은 전극층으로부터 약 3㎜ 이내를 터치해서는 안되는 비유효 영역(Non-effective Touch Area ; NTA)(A)를 두고 있다.However, the resistive touch panel has an electrode layer formed of silver (Ag) for the X and Y-axis electric fields required for coordinate recognition, and the transparent electrode layer attached to the upper and lower substrates of the touch panel has a gap corresponding to the height of the electrode layer. exist. In this case, when the gap is pressed by the stylus pen or the finger toward the edge where the electrode layer is formed, there is a problem that a crack occurs in the upper transparent electrode layer. For this reason, the resistive touch panel has a non-effective touch area (NTA) A which should not touch within about 3 mm from the electrode layer.
이러한 저항막 방식 터치패널에서 스타일러스 펜 또는 손가락에 의한 내구성을 향상시키기 위해서는 최소한 전극층 영역과 비유효 영역(NTA)를 감안하여 최소 5.6㎜ 이상의 여유 마진이 필요하게 된다. 그러나, 종래기술에 따른 터치패널 일체형 액정표시모듈에서 5.6㎜ 이상의 여유 마진을 적용하기에는 무리가 있다.In order to improve durability by a stylus pen or a finger in the resistive touch panel, a margin of at least 5.6 mm is required in consideration of at least the electrode layer region and the ineffective region (NTA). However, it is unreasonable to apply a margin of 5.6 mm or more in the touch panel integrated liquid crystal display module according to the prior art.
따라서, 본 발명의 목적은 탑케이스를 부가한 뒤 부가된 탑케이스 영역까지 터치패널을 연장하여 여유마진을 확보함으로써 터치패널의 내구성 향상시킬 수 있도록 한 더블 탑케이스를 이용한 터치패널 일체형 액정표시모듈을 제공하는 데 있다.Accordingly, an object of the present invention is to provide a touch panel integrated liquid crystal display module using a double top case to improve durability of the touch panel by securing a margin by extending the touch panel to the added top case area after adding the top case. To provide.
