Description

표시장치Display

본 발명은 표시장치에 관한 것으로, 좀더 상세하게는 PCB를 램프 인접부에 배치하고, 이와 연결된 TCP를 램프를 감싼 몰드 프레임의 외주면을 따라 구부려 형성시킴으로써, 램프 반대쪽의 모듈크기를 적절히 박형화할 수 있도록 한 표시장치에 관한 것이다.The present invention relates to a display device, and more particularly, by placing a PCB in the vicinity of a lamp and forming a TCP connected thereto by bending it along the outer circumferential surface of a mold frame surrounding the lamp, so that the module size on the opposite side of the lamp can be appropriately thinned. It relates to a display device.

최근, LCD 모듈 제작시, 박형 구조를 가지면서도 전체 LCD 모듈 면적에 대한 LCD 패널의 유효면적 비율을 가능한한 확대시켜 주기 위하여 LCD 패널의 TFT 기판에 구동 드라이버 IC를 TCP(Tape Carrier Package)를 적용한 TAB(Tape Automated Bonding) 실장기술을 이용하여 전기적으로 연결해 주고 있다.Recently, in manufacturing LCD modules, TAB using a drive driver IC (Tape Carrier Package) is applied to the TFT substrate of the LCD panel in order to enlarge the effective area ratio of the LCD panel to the total LCD module area as much as possible while having a thin structure. (Tape Automated Bonding) Electrically connected using mounting technology.

이러한 TAB 실장기술은 크게, LCD 패널에 TCP를 접속하는 공정과, 이러한 TCP를 PCB(Printed Circuit Board)에 접속하는 공정으로 나뉘어지며, 이때 사용되는 TCP로는 슬립 타입(Slip type)의 TCP와, 밴트 타입(Bent type)의 TCP를 들 수 있다.The TAB mounting technology is largely divided into a process of connecting TCP to an LCD panel, and a process of connecting such TCP to a printed circuit board (PCB). In this case, the TCP used is a slip type TCP and a band. Bent type TCP can be mentioned.

도 1은 이러한 기능을 수행하는 종래의 슬립 타입 TCP를 적용한 LCD 모듈의 구조를 개략적으로 도시한 단면도이고, 도 2는 종래의 밴트 타입 TCP를 적용한 LCD모듈의 구조를 개략적으로 도시한 단면도이다.1 is a cross-sectional view schematically showing a structure of an LCD module to which a conventional sleep type TCP is applied to perform such a function, and FIG. 2 is a cross-sectional view schematically showing a structure of an LCD module to which a conventional vant type TCP is applied.

도 1에 도시된 바와 같이, 슬립 타입 TCP를 적용한 LCD 모듈에서 화상정보를 디스플레이하는 LCD 패널(4)의 측부에는 빛을 제공하는 램프(1)가 배치되며 이러한 램프(1)는 램프 반사판(9)에 의해 감싸진다.As shown in FIG. 1, a lamp 1 for providing light is disposed on the side of the LCD panel 4 displaying image information in the LCD module to which the sleep type TCP is applied, and the lamp 1 includes a lamp reflector 9. Wrapped by)

이때, 램프(1)의 측부에는 램프(1)에서 제공된 빛을 상술한 LCD 패널(4)로 전달하는 도광판(2)이 배치되며, 이러한 램프(1), 램프 반사판(9) 및 도광판(2)은 몰드 프레임(3)에 의해 감싸져 보호된다. 여기서, 도면부호 5는 칼라필터 기판을 나타낸다.At this time, the light guide plate 2 for transmitting the light provided from the lamp 1 to the above-described LCD panel 4 is disposed on the side of the lamp 1, such a lamp 1, the lamp reflector 9 and the light guide plate 2. ) Is wrapped and protected by the mold frame 3. Here, reference numeral 5 denotes a color filter substrate.

한편, LCD 패널(4)의 측부에는 소정의 구동신호를 출력하는 PCB(6)가 배치되는 바, 이러한 PCB(6) 상에는 구동 IC(7)가 TCP(8)에 얹혀져 배치되며, TCP(8)는 PCB(6)와 LCD 패널(4)을 서로 연결하여, PCB(6)에서 출력되는 구동신호가 구동IC(7)를 거쳐 LCD 패널(4)로 전달되도록 한다.On the other hand, a PCB 6 for outputting a predetermined drive signal is disposed on the side of the LCD panel 4, and on the PCB 6, the driver IC 7 is placed on the TCP 8, and the TCP 8 is disposed. ) Connects the PCB 6 and the LCD panel 4 to each other so that the driving signal output from the PCB 6 is transferred to the LCD panel 4 via the driving IC 7.

이러한 슬립 타입 TCP를 적용한 LCD 모듈에서는 램프형성영역(A) 및 유효발광면적(B)을 확보해야함과 아울러 램프(1) 반대쪽에 상술한 PCB(6)가 배치될 수 있는 영역(C)을 적절히 확보하여야 한다.In the LCD module to which the sleep type TCP is applied, the lamp forming area A and the effective light emitting area B must be secured, and the area C where the above-described PCB 6 can be disposed is disposed on the opposite side of the lamp 1. It must be secured.

한편, 도 2에 도시된 바와 같이, 밴트 타입 TCP를 적용한 LCD 모듈은 상술한 슬립 타입 TCP를 적용한 LCD 모듈과 유사한 형상을 갖지만, 이에 비해, TCP(8)를 구부려 형성하고, 이와 연결되는 PCB(6)를 도광판(2) 하부에 배치하는 등의 다른 점이 있다.On the other hand, as shown in Figure 2, the LCD module applying the vant type TCP has a similar shape to the LCD module applying the sleep type TCP described above, in contrast, by forming a bent TCP (8), the PCB ( 6) is disposed below the light guide plate 2.

여기서, 도광판(2)은 PCB(6)가 배치될 수 있도록 경사(Wedge)를 이루며, 이러한 경사면의 저부에는 상술한 PCB(6)가 배치된다. 이때, PCB(6)는 넓은 실장공간이 확보된 램프(1)의 반대쪽에 위치한다.Here, the light guide plate 2 forms a wedge so that the PCB 6 may be disposed, and the above-described PCB 6 is disposed at the bottom of the inclined surface. At this time, the PCB (6) is located on the opposite side of the lamp (1) secured a large mounting space.

이러한 밴트 타입 TCP(8)를 적용한 LCD 모듈에서는 슬립 타입 TCP를 적용한 LCD 모듈과 달리 PCB(6)를 도광판(2)의 저부에 배치하고, TCP(8)의 형상을 밴드 타입으로 형성시킴으로써, PCB(6) 배치영역을 어느정도 줄일 수 있는 효과가 있다. 그러나, 이러한 경우에도 램프(1) 반대쪽에 PCB(6)가 배치되는 최소한의 영역(C)은 적절히 확보되어야 한다. In the LCD module to which the Bent type TCP 8 is applied, unlike the LCD module to which the sleep type TCP is applied, the PCB 6 is disposed on the bottom of the light guide plate 2, and the shape of the TCP 8 is formed into a band type. (6) It is effective to reduce the area to some extent. However, even in this case, the minimum area C in which the PCB 6 is disposed opposite the lamp 1 must be adequately secured.

그러나, 이러한 구성을 갖는 종래의 LCD 모듈의 구조에는 몇 가지 중대한 문제점이 있다.However, there are some serious problems in the structure of a conventional LCD module having such a configuration.

첫째, 슬립 타입 TCP를 적용하는 LCD 모듈의 경우, 상술한 바와 같이, 램프 반대쪽에 PCB가 배치될 수 있는 영역이 적절히 확보되어야 하는 바, 이에 따라, 전체적인 모듈의 크기가 증가하게 됨으로써, 최근의 장치 박형화 요구에 적절히 대응할 수 없는 심각한 문제점이 있다.First, in the case of the LCD module to which the sleep type TCP is applied, as described above, an area in which the PCB can be disposed on the opposite side of the lamp must be adequately secured. Accordingly, the size of the overall module is increased. There is a serious problem that cannot adequately respond to thinning demands.

둘째, 밴트 타입 TCP를 적용하는 LCD 모듈의 경우에도, 상술한 바와 같이, 램프 반대쪽에 PCB가 배치될 수 있는 최소한의 영역이 적절히 확보되어야 하는 바, 이에 따라, 전체적인 모듈의 크기가 증가하게 됨으로써, 상술한 슬립 타입 TCP를 적용하는 LCD 모듈과 마찬가지로 최근의 장치 박형화 요구에 적절히 대응할 수 없는 심각한 문제점이 있다.Secondly, even in the case of the LCD module to apply the Bent type TCP, as described above, the minimum area in which the PCB can be placed on the opposite side of the lamp must be properly secured, so that the overall size of the module is increased, Like the LCD module applying the sleep type TCP described above, there is a serious problem in that it cannot adequately cope with the recent device thinning demand.

따라서, 본 발명의 목적은 램프형성영역을 활용하여 상술한 PCB를 도광판의 입광부쪽에 배치하고, TCP를 램프쪽으로 밴트시켜, 램프 반대쪽의 PCB 배치영역이 현저히 줄어들도록 함으로써, 전체적인 모듈 크기를 양호하게 박형화할 수 있도록 하는 LCD 모듈의 구조를 제공함에 있다. Accordingly, an object of the present invention is to use the lamp forming area to arrange the above-described PCB on the light-receiving part side of the light guide plate, and to bend the TCP toward the lamp so that the PCB arrangement area on the opposite side of the lamp is significantly reduced, thereby making the overall module size satisfactory. To provide a structure of the LCD module that can be thinned.

상기와 같은 목적을 달성하기 위한 본 발명은 몰드 프레임과; 상기 몰드 프레임에 의해 감싸져 램프 반사판 내에 형성된 램프로부터 발산되는 빛을 LCD 패널로 전달하는 도광판과; 상기 도광판의 입광부쪽 일측부에 배치되어 상기 LCD 패널을 구동하는 PCB와; 상기 PCB와 연결되어 구동 IC를 탑재한 상태로 상기 램프 반사판의 외측을 감싼 상기 몰드 프레임의 외주면을 따라 굴곡되어 상기 LCD 패널과 연결되는 TCP를 포함하는 것을 특징으로 한다.The present invention for achieving the above object is a mold frame; A light guide plate wrapped by the mold frame to transfer light emitted from the lamp formed in the lamp reflection plate to the LCD panel; A PCB disposed at one side of the light incidence part of the light guide plate to drive the LCD panel; And a TCP connected to the PCB and connected to the LCD panel by bending along an outer circumferential surface of the mold frame surrounding the outside of the lamp reflector while the driving IC is mounted thereon.

바람직하게, 상기 램프 반사판은 PET 재질인 것을 특징으로 한다.Preferably, the lamp reflector is characterized in that the PET material.

바람직하게, 상기 램프 반사판은 Al 재질인 것을 특징으로 한다.Preferably, the lamp reflector is characterized in that the Al material.

바람직하게, 상기 램프 반사판은 황동 재질인 것을 특징으로 한다.Preferably, the lamp reflector is characterized in that the brass material.

바람직하게, 상기 PCB의 평면형상은 "L"형상인 것을 특징으로 한다. Preferably, the planar shape of the PCB is characterized in that the "L" shape.

이에 따라, 본 발명에서는 전체 모듈의 크기가 현저히 박형화된다.Accordingly, in the present invention, the size of the entire module is remarkably thinned.

이하, 첨부된 도면을 참조하여 본 발명에 따른 LCD 모듈의 구조를 좀더 상세히 설명하면 다음과 같다.Hereinafter, the structure of the LCD module according to the present invention will be described in detail with reference to the accompanying drawings.

도 3은 본 발명에 따른 LCD 모듈의 구조를 개략적으로 도시한 사시도이고, 도 4는 이의 단면도이다.3 is a perspective view schematically showing the structure of the LCD module according to the present invention, Figure 4 is a cross-sectional view thereof.

도시된 바와 같이, 본 발명에 따른 LCD 모듈의 구조는 몰드 프레임(3)과, 몰드 프레임(3)에 의해 감싸져 램프 반사판(12) 내에 형성된 램프(1)로부터 발산되는 빛을 LCD 패널(4)로 전달하는 도광판(2)과, 도광판(2)의 입광부쪽 저부에 배치되어 LCD 패널(4)을 구동하는 PCB(10)와, PCB(10)와 연결되어 구동 IC(7)를 탑재한 상태로 램프 반사판(12)의 외측을 감싼 몰드 프레임(3)의 외주면을 따라 굴곡되어 LCD 패널(4)과 연결되는 TCP(11)를 포함한다.As shown, the structure of the LCD module according to the present invention is the LCD panel 4 by the mold frame 3, and the light emitted from the lamp (1) formed in the lamp reflector 12 wrapped by the mold frame (3) A light guide plate (2) to be delivered to the light guide plate, a PCB (10) disposed at the bottom of the light receiving unit side of the light guide plate (2) to drive the LCD panel (4), and a driving IC (7) connected to the PCB (10). It includes a TCP (11) which is bent along the outer circumferential surface of the mold frame (3) surrounding the outside of the lamp reflector (12) in one state and connected to the LCD panel (4).

이때, 상술한 바와 같이, 도광판(2)은 경사를 이루며 형성되는 바, 이러한 경사면의 저부에는 PCB(10)가 배치된다.At this time, as described above, the light guide plate 2 is formed to be inclined, and the PCB 10 is disposed at the bottom of the inclined surface.

여기서, 도 4에 도시된 바와 같이, 본 발명에 따른 PCB(10)의 위치는 종래의 램프(1) 반대쪽에서 램프(1) 인접부로 이동된다. 이에 따라, TCP(11)는 용이하게 램프(1)를 감싼 몰드 프레임(3)의 외주면을 따라 굽어질 수 있다.Here, as shown in FIG. 4, the position of the PCB 10 according to the invention is moved from the opposite side of the conventional lamp 1 to the lamp 1 adjacency. Accordingly, the TCP 11 can be easily bent along the outer circumferential surface of the mold frame 3 surrounding the lamp 1.

한편, 도 3에 도시된 바와 같이, PCB(10)의 평면형상은 "L"형상을 이룬다. 이의 효과를 설명한다.On the other hand, as shown in Figure 3, the planar shape of the PCB 10 forms an "L" shape. Explain the effect of this.

상술한 바와 같이, 도광판(2)은 경사를 이루며 형성되는데, 그 결과, 램프(1) 반대쪽으로 갈수록 더 넓은 실장공간이 확보된다. 이때, 본 발명의 PCB(10)는 "L"형상을 이루는 바, 이에 따라, 부피가 큰 회로부품(10a)은 램프(1) 반대쪽으로 연장되어 양호한 실장공간을 확보하고 있는 PCB(10) 면(10b)에 적절히 실장될 수 있다.As described above, the light guide plate 2 is formed to be inclined, and as a result, a larger mounting space is secured toward the opposite side of the lamp 1. At this time, the PCB 10 of the present invention forms an "L" shape, whereby the bulky circuit part 10a extends to the opposite side of the lamp 1 to secure a good mounting space. It may be appropriately mounted at 10b.

이때, 상술한 바와 같이, PCB(10)와 연결된 TCP(11)는 구동 IC(7)를 탑재한 상태로 램프 반사판(12) 외측의 몰드 프레임(3)의 외주면을 따라 연장되어 LCD 패널(4)에 연결된다.In this case, as described above, the TCP 11 connected to the PCB 10 extends along the outer circumferential surface of the mold frame 3 outside the lamp reflector 12 with the driving IC 7 mounted thereon, thereby extending the LCD panel 4. )

종래의 경우, PCB는 램프 반대쪽에 위치되었고, 이러한 PCB와 연결된 TCP는 램프 반대쪽을 감싸고 있는 몰드 프레임의 외주면을 따라 굽어져 LCD 패널에 연결되었다. 이에 따라, 램프 반대쪽의 모듈에는 PCB를 실장하기 위한 최소한의 영역이 확보되어야 함으로써, 장치 전체를 박형화하기가 어려운 문제점이 있었다.In the conventional case, the PCB was positioned opposite the lamp, and the TCP connected to this PCB was bent along the outer circumferential surface of the mold frame surrounding the lamp and connected to the LCD panel. Accordingly, since the minimum area for mounting the PCB must be secured in the module opposite to the lamp, it is difficult to thin the entire device.

그러나, 본 발명의 경우, 상술한 바와 같이, PCB(10)는 램프형성영역(A)을 활용하여 램프(1)쪽에 위치되고, 이러한 PCB(10)와 연결된 TCP(11)는 램프 반사판(12)을 감싸고 있는 몰드 프레임(3)의 외주면을 따라 굽어져 LCD 패널(4)에 연결됨으로써, 램프(1) 반대쪽의 모듈영역(C)을 현저히 줄일수 있고, 그 결과 양호하게 장치를 박형화할 수 있다.However, in the case of the present invention, as described above, the PCB 10 is located on the lamp 1 side utilizing the lamp forming area A, and the TCP 11 connected to the PCB 10 is the lamp reflector 12. By bending along the outer circumferential surface of the mold frame 3 surrounding the mold frame 3 and connecting it to the LCD panel 4, the module area C on the opposite side of the lamp 1 can be significantly reduced, and as a result, the device can be thinly formed well. have.

이때, 본 발명의 특징에 따르면, 램프 반사판(12)은 PET 재질 또는 Al 재질 또는 황동 재질의 금속판으로 형성된다. 이의 효과를 설명한다.At this time, according to the feature of the present invention, the lamp reflector 12 is formed of a metal plate of PET material or Al material or brass material. Explain the effect of this.

상술한 바와 같이, 본 발명의 TCP(11)는 램프 반사판(12)의 외측을 감싼 몰드 프레임(3)의 외주면을 따라 굽어져 연장·형성되는 바, 이에 따라, 램프(1)에서 발생되는 열이 TCP(11)에 전달될 수 있는 문제점이 야기될 수 있다.As described above, the TCP 11 of the present invention is bent and extended along the outer circumferential surface of the mold frame 3 surrounding the outside of the lamp reflector 12, thereby forming heat generated by the lamp 1. This may cause problems that may be communicated to TCP 11.

그러나, 본 발명의 경우, 상술한 바와 같이, 양호한 방열 기능을 갖춘 PET, Al, 황동 등을 램프 반사판(12)의 재질로 사용함으로써, 램프(1)에서 발생된 열이 TCP(11)에 전달되는 문제점을 적절히 해결한다.However, in the case of the present invention, as described above, by using PET, Al, brass and the like having a good heat dissipation function as the material of the lamp reflector 12, heat generated in the lamp 1 is transmitted to the TCP (11) Resolve the problem as appropriate.

더욱이, 램프 반사판(12) 및 TCP(11) 사이에는 몰드 프레임(3)이 추가로 개재됨으로써, 램프(1)에서 발생된 열은 TCP(11)에 쉽게 전달될 수 없다.Moreover, since the mold frame 3 is further interposed between the lamp reflector 12 and the TCP 11, heat generated in the lamp 1 cannot be easily transferred to the TCP 11.

한편, 이러한 램프 반사판(12)에는 은(Ag)이 도금됨으로써, 램프 반사판(12)은 상술한 열 전달 방지 기능과 더불어 본연의 빛 반사 기능도 적절히 수행할 수 있다.On the other hand, the silver plate (Ag) is plated on the lamp reflector 12, the lamp reflector 12 can perform a proper light reflection function in addition to the heat transfer prevention function described above.

이 후, PCB(10)로부터 출력된 구동 신호는 TCP(11)상에 탑재된 구동 IC(7)를 거쳐 LCD 패널(4)로 출력되고 이에 따라, LCD 패널(4) 및 칼라필터 기판(5)에는 소정의 화상정보가 디스플레이된다.Thereafter, the drive signal output from the PCB 10 is output to the LCD panel 4 via the drive IC 7 mounted on the TCP 11, and accordingly, the LCD panel 4 and the color filter substrate 5 ), Predetermined image information is displayed.
