본 발명은 액정모듈의 터치패널 결합구조에 관한 것이다.The present invention relates to a touch panel coupling structure of a liquid crystal module.

액정패널은 통상 2매의 도전성 유리기판을 평행하게 배치하고, 그 사이에 유전이방성(誘電異方性)을 갖는 액정을 주입하며, 외부로부터 인가되는 전압 변화에 따라 달라지는 액정의 편광 성질을 이용해 디스플레이하는 방식이다. 즉, 주입된 액정의 광 투과율이 조절 되게 함으로써 화상을 표시하게 된다. 이러한 액정패널은 입력장치로 사용되는 터치패널(Touch Panel)을 탑재하기도 한다. 터치패널은 스타일러스 펜 또는 손가락이 눌려진 위치에 저항 또는 전류 값의 변화를 발생함으로써 사용자가 지정하는 명령 또는 그래픽 정보를 입력하게 된다. 또한, 터치패널에는 정전용량 방식의 터치패널과 저항막 방식의 터치패널이 주로 사용되고 있다.A liquid crystal panel usually arranges two conductive glass substrates in parallel, injects a liquid crystal having dielectric anisotropy therebetween, and uses a polarization property of the liquid crystal to vary according to a voltage change applied from the outside. That's the way it is. That is, the image is displayed by adjusting the light transmittance of the injected liquid crystal. Such liquid crystal panels may also include a touch panel used as an input device. The touch panel generates a change in the resistance or current value at the position where the stylus pen or finger is pressed to input a command or graphic information designated by the user. In addition, a capacitive touch panel and a resistive touch panel are mainly used for the touch panel.

이하, 종래의 액정모듈의 각 구성부와 이들 구성부가 갖는 단점을 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, each component of the conventional liquid crystal module and the disadvantages of these components will be described in detail with reference to the drawings.

도 1은 종래 기술에 따른 액정모듈의 분해상태를 도시한 사시도이며, 도 2는 종래 기술에 따른 액정모듈의 단면을 도시한 도면이다.1 is a perspective view showing an exploded state of a liquid crystal module according to the prior art, Figure 2 is a view showing a cross section of the liquid crystal module according to the prior art.

도 1 내지 도 2에 도시된 바와 같이 종래의 액정모듈은, 2매의 도전성 유리판재 사이에 액정물질이 채워진 액정패널(10)과, 상기 액정패널(10)은 자체 발광력이 없기 때문에 디스플레이를 위한 광원으로서 백라이트 유닛(미도시)이 구비되어 빛을 조사하고, 제어신호 및 데이터 신호를 전달하기 위하여 액정패널(10)과 전기적으로 연결된 연성회로기판(미도시)으로 구성되며, 상기 언급된 각 구성요소들을 고정 및 체결시키기 위한 프레임(30)을 포함하여 구성된다.As shown in FIGS. 1 and 2, the conventional liquid crystal module includes a liquid crystal panel 10 in which a liquid crystal material is filled between two conductive glass plates, and the liquid crystal panel 10 has no self-luminous power. As a light source for the backlight unit (not shown) is provided with a flexible circuit board (not shown) electrically connected to the liquid crystal panel 10 in order to irradiate light and to transmit control signals and data signals, And a frame 30 for fastening and fastening the components.

이때, 액정패널(10)이 수용된 프레임(30)의 전면으로 다각형 틀 형상의 샤시프레임(40)이 결합되고, 상기 샤시프레임(40)의 전면 가장자리를 따라 양면테이프(50)가 점착되며, 상기 양면테이프(50)는 양측면에 점착제가 도포된 형태로 구비되어 샤시프레임(40)과 점착되는 반대쪽으로 터치패널(20)이 점착되어 종래의 액정모듈이 구성된다.In this case, the chassis frame 40 having a polygonal frame shape is coupled to the front of the frame 30 in which the liquid crystal panel 10 is accommodated, and the double-sided tape 50 is adhered along the front edge of the chassis frame 40. The double-sided tape 50 is provided in a form in which adhesives are applied to both sides, and the touch panel 20 is adhered to the opposite side to be adhered to the chassis frame 40 to form a conventional liquid crystal module.

그러나, 이러한 종래의 액정모듈은 터치패널(20)을 양면테이프(50)의 점착력을 이용하여 샤시프레임(40)에 결합함으로 인해, 터치패널(20)의 조립 및 분해시 양면테이프(50)의 점착부가 샤시프레임(40)에 전이되어 재활용이 어려운 문제점이 있게 되며, 양면테이프(50) 및 샤시프레임(40)의 사용으로 부품, 공정수가 증가되고, 터치패널(20)이 정확하게 장착되지 않았을시 양면테이프(50)에 의해 재조립이 어려워 2차불량이 발생되는 문제점이 있게 된다.However, such a conventional liquid crystal module is coupled to the chassis frame 40 by using the adhesive force of the double-sided tape 50, the liquid crystal module of the double-sided tape 50 when assembling and disassembling the touch panel 20 When the adhesive portion is transferred to the chassis frame 40, there is a problem that it is difficult to recycle, and when the double-sided tape 50 and the chassis frame 40 are used, the number of parts and processes increases, and the touch panel 20 is not correctly mounted. Reassembly is difficult by the double-sided tape 50, there is a problem that secondary defects occur.

또한, 양면테이프(50)의 상호 접착되는 방식은, 온도나 습도와 같은 환경조건의 영향에 따라 양면테이프(50)의 물성치가 변화하게 되므로, 사용에 따라 양면테이프(50)의 접착력이 약화되어 샤시프레임(40)에 부착된 터치패널(20)이 떨어지는 문제점이 있게 된다.In addition, in the method of bonding the double-sided tape 50 to each other, since the physical properties of the double-sided tape 50 change according to the influence of environmental conditions such as temperature and humidity, the adhesive force of the double-sided tape 50 is weakened depending on the use. There is a problem that the touch panel 20 attached to the chassis frame 40 falls.

따라서, 본 발명은 프레임의 고정부를 이용하여 양면테이프를 이용하지 않고 기계적인 구조에 의해 터치패널이 고정되도록 함으로서 견고한 액정모듈의 터치패널 결합구조를 제공한다.Accordingly, the present invention provides a rigid touch panel coupling structure of the liquid crystal module by fixing the touch panel by a mechanical structure without using a double-sided tape by using the fixing portion of the frame.

본 발명은 내부로 액정패널 수용부가 형성되며, 고정부가 형성되는 프레임, 상기 액정패널 수용부에 수용되는 액정패널 및 상기 고정부에 의해 고정되는 터치패널을 포함한다.The present invention includes a liquid crystal panel accommodating part formed therein, a frame in which a fixing part is formed, a liquid crystal panel accommodated in the liquid crystal panel accommodating part, and a touch panel fixed by the fixing part.

이하, 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자가 본 발명을 용이하게 실시할 수 있을 정도로 본 발명의 바람직한 실시 예를 첨부된 도면을 참조하여 상세하게 설명하면 다음과 같다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings such that those skilled in the art may easily implement the present invention.

도 3은 본 발명의 일 실시예에 따른 액정모듈의 분해상태를 도시한 사시도이고, 도 4는 도 3의 결합상태를 도시한 사시도이며, 도 5는 도 4의 'a-a'부 단면을 도시한 도면이다.3 is a perspective view illustrating an exploded state of a liquid crystal module according to an embodiment of the present invention, FIG. 4 is a perspective view illustrating a coupled state of FIG. 3, and FIG. 5 is a cross-sectional view of the 'a-a' part of FIG. 4. Figure is shown.

도 3 내지 도 5에 도시된 바와 같이 본 발명에 따른 액정모듈(A)은 디스플레이를 위한 액정패널(100)과, 입력장치로 사용되는 터치패널(200) 및 상기 언급된 각 구성요소들을 고정 및 체결시키기 위한 프레임(300)을 포함하여 구성된다.As shown in FIGS. 3 to 5, the liquid crystal module A according to the present invention fixes and fixes the liquid crystal panel 100 for a display, the touch panel 200 used as an input device, and the above-mentioned components. It is configured to include a frame 300 for fastening.

액정패널(100)은 상부면에 편광판(미도시)이 부착되고 상하 유리판재 사이에는 연성회로기판(미도시)이 삽입된다. 액정패널(100)은 자체 발광력이 없기 때문에 디스플레이를 위한 광원으로서 백라이트 유닛(미도시)이 액정패널(100)의 일측에 위치하여 액정패널(100)에 빛을 조사하게 된다.The liquid crystal panel 100 has a polarizing plate (not shown) attached to an upper surface thereof, and a flexible circuit board (not shown) is inserted between upper and lower glass plates. Since the liquid crystal panel 100 does not have self-luminous power, a backlight unit (not shown) as a light source for the display is positioned on one side of the liquid crystal panel 100 to irradiate light to the liquid crystal panel 100.

일반적으로 사용되고 있는 백라이트 유닛(미도시)은 광을 발생하는 광원 및 발생된 광을 액정패널(100)로 안내하기 위한 도광판을 포함한다. 상기 광원은 상기 도광판의 일측면(혹은 양측면)에 위치하며, 발광 다이오드(Light Emitting Diode;LED)로 형성된다.A backlight unit (not shown) which is generally used includes a light source for generating light and a light guide plate for guiding the generated light to the liquid crystal panel 100. The light source is positioned on one side (or both sides) of the light guide plate and is formed of a light emitting diode (LED).

터치패널(200)은 액정패널(100)의 디스플레이 광이 투과 가능하게 형성되며, 스타일러스 펜 또는 손가락이 눌려진 위치에 해당하는 저항 또는 전류 값의 변화를 발생함으로써 사용자가 지정하는 명령 또는 그래픽 정보를 입력하게 된다. 또한, 터치패널(200)에는 정전용량 방식의 터치패널과 저항막 방식의 터치패널이 주로 사용되고 있다.The touch panel 200 is formed to transmit the display light of the liquid crystal panel 100, and inputs a command or graphic information designated by a user by generating a change in a resistance or current value corresponding to a position where a stylus pen or a finger is pressed. Done. In addition, a capacitive touch panel and a resistive touch panel are mainly used for the touch panel 200.

이의 동작을 설명하면, 터치패널(200)의 상부를 일정 이상의 압력으로 터치를 하게 되면, 그 위치에서의 저항값의 변화가 터치 컨트롤러(미도시)에서 계산되어 좌표를 인식하게 된다. Referring to this operation, when the upper portion of the touch panel 200 is touched with a predetermined pressure or more, a change in the resistance value at the position is calculated by the touch controller (not shown) to recognize the coordinates.

이와 같은, 일정 이상의 압력의 터치로 명령 또는 그랙픽 정보를 입력하는 터치패널(200)은 이미 종래에 많이 사용되고 있는 것이므로, 이에 대한 내부 구조 및 동작에 관한 상세한 설명은 생략한다.Since the touch panel 200 that inputs a command or graphic information by a touch of a predetermined pressure or more is already used in the related art, detailed descriptions on the internal structure and operation thereof will be omitted.

이러한 액정패널(100) 및 터치패널(200)은 프레임(300)에 안착 고정된다. 이때, 프레임(300)의 내부에는 소정의 액정패널 안착부(310)가 형성되어 액정패널(100) 및 백라이트 유닛(미도시)이 수용되고, 상기 액정패널 안착부(310)의 외부 방향 양측으로 복수의 고정부(320)가 형성되어 상기 터치패널(200)을 액정패널(100) 전면으로 결합 된다.The liquid crystal panel 100 and the touch panel 200 are seated and fixed to the frame 300. In this case, a predetermined liquid crystal panel mounting part 310 is formed inside the frame 300 to accommodate the liquid crystal panel 100 and a backlight unit (not shown), and to both sides of the liquid crystal panel mounting part 310 in an external direction. A plurality of fixing parts 320 are formed to couple the touch panel 200 to the front of the liquid crystal panel 100.

터치패널(200)의 결합구조를 좀 더 자세히 살펴보면, 프레임(300)의 고정부(320)에는 터치패널(200)의 두께에 해당하는 삽입홈(321)이 형성되는데, 이는 삽입홈(321)의 하단이나 상단으로 터치패널(200)을 슬라이딩 삽입하여 양측에서 지지하는 구성이다. 이와 같은 구성은 양측의 고정부(320)가 서로 마주보는 방향으로 탄성력을 인가하도록 형성되어 안정적으로 터치패널(200)을 고정하게 된다.Looking at the coupling structure of the touch panel 200 in more detail, the fixing portion 320 of the frame 300 is formed with an insertion groove 321 corresponding to the thickness of the touch panel 200, which is the insertion groove 321 Sliding insert the touch panel 200 to the bottom or top of the configuration to support from both sides. Such a configuration is formed to apply elastic force in a direction in which both fixing parts 320 face each other, thereby stably fixing the touch panel 200.

또한, 삽입홈(321)의 터치패널(200)과 마주하는 면에는 고무재(미도시)가 추가로 부착되거나, 고정부(320)에 고무재(미도시)를 일체로 사출성형하여 구성하여, 터치패널(200)의 고정시 미끄러짐에 의한 흔들림을 방지할 수 있다. In addition, a rubber material (not shown) may be additionally attached to a surface facing the touch panel 200 of the insertion groove 321, or may be configured by injection molding a rubber material (not shown) integrally with the fixing part 320. When the touch panel 200 is fixed, shaking due to slippage may be prevented.

한편, 프레임(300)의 고정부(320)에는 경사부(322)가 형성되어 터치패널(200)을 전면에서 삽입하여 고정할 수도 있는데, 이는 고정부(320)가 탄성력을 가지는 판스프링(미도시)으로 별로로 형성되어 실현이 가능함은 물론, 프레임(300)과 일체형으로 형성된 고정부(320) 재질이 탄성력을 충분히 발휘할 수 있는 합성수지로도 충분히 실현 가능함을 밝혀둔다.On the other hand, the inclined portion 322 is formed on the fixing portion 320 of the frame 300 may be fixed by inserting the touch panel 200 from the front, which is fixed plate 320 (spring not having elastic force) In addition, it is possible to realize that it is formed separately as a star, as well as that the fixing part 320 formed integrally with the frame 300 can be sufficiently realized as a synthetic resin capable of sufficiently exerting elastic force.

여기서, 경사부(322)를 통한 결합구조를 설명하면, 경사부(322)에 터치패널(200)을 위치시킨 후 액정패널(100) 방향으로 힘을 가해주면, 경사부(322)는 터치패널(200)의 결합부(201)를 타면서 고정부(320)는 프레임(300)의 외측의 벌어지고, 상기한 상태에서 더 힘을 가해주면 터치패널(200)이 삽입홈(321)에 위치하여 끼워 맞춤 되어 고정부(320)의 서로 마주보는 방향의 탄성력에 의해 삽입홈(321)과 터치패널(200)의 결합부(201)는 밀착하여 결합된다.Here, when describing the coupling structure through the inclined portion 322, after placing the touch panel 200 on the inclined portion 322 and applying a force toward the liquid crystal panel 100, the inclined portion 322 is a touch panel The fixing part 320 is opened on the outside of the frame 300 while riding the coupling part 201 of the 200, and when the force is applied in the above state, the touch panel 200 is positioned in the insertion groove 321. The fitting groove 201 and the coupling part 201 of the touch panel 200 are closely coupled to each other by the elastic force of the fixing part 320 facing each other.

이상의 설명에서는 고정부(320)를 프레임(300)의 일체로 형성된 상태로 설명하였지만, 이를 한정하는 것은 아니고, 상기 고정부(320)는 일체가 아닌 개별구성으로서 구성이 가능함은 물론, 상술한 바와 같이 판스프링으로 구성되어도 동일한 효과를 가지게 된다.In the above description, the fixing part 320 has been described as being integrally formed with the frame 300, but the present invention is not limited thereto, and the fixing part 320 may be configured as an individual component instead of an integral part. Even if it is configured as a leaf spring will have the same effect.

도 6은 본 발명의 다른 일 실시예에 따른 액정모듈의 정면을 도시한 도면이다.6 is a diagram illustrating a front surface of a liquid crystal module according to another embodiment of the present invention.

도 6에 도시된 프레임(300)은 도 3에서와 같이 프레임의 양측에 고정부(320)가 형성되고 이에 더하여 프레임(300)의 상,하부에도 삽입홈(321')과, 경사부(322')가 구비된 고정부(320')를 추가하여, 도 3에 도시된 프레임(300)과는 달리 양측 및 상, 하부를 동시에 고정부(320,320')에 의해 고정됨으로써 더욱더 안정적으로 고정된다.In the frame 300 illustrated in FIG. 6, fixing portions 320 are formed at both sides of the frame as shown in FIG. 3, and in addition, the insertion grooves 321 ′ and the inclined portions 322 are formed at upper and lower portions of the frame 300. In addition to the fixed part 320 'provided with'), unlike the frame 300 shown in FIG. 3, both sides, and the upper and lower parts are fixed by the fixing parts 320 and 320 'at the same time to be fixed more and more stable.
