본 발명은 액정표시장치의 커넥터에 관한 것으로, 더욱 상세하게는 액정표시장치의 인쇄회로기판과 컴퓨터 본체간의 인터페이스를 위해 사용되는 커넥터의 구조를 개선하여 인쇄회로기판의 설계를 단순화시키고 LVDS(Low Voltage Differential Signaling) 방식으로 전송되는 각종 신호들을 안정화시킨 액정표시장치의 커넥터에 관한 것이다.The present invention relates to a connector of a liquid crystal display device, and more particularly, to improve the structure of a connector used for the interface between a printed circuit board and a computer main body of the liquid crystal display device, simplifying the design of the printed circuit board and providing a low voltage (LVDS). The present invention relates to a connector of a liquid crystal display device which stabilizes various signals transmitted by a differential signaling method.

일반적으로 사용되고 있는 표시장치들 중의 하나인 음극선관(CRT;Cathode Ray Tube)은 텔레비전을 비롯해서 계측기기, 정보 단말기기 등의 모니터에 주로 이용되고 있으나, 음극선관의 자체 무게와 크기로 인하여 전자 제품의 소형화, 경량화의 요구에 적극 대응할 수 없었다.Cathode ray tube (CRT), which is one of the commonly used display devices, is mainly used for monitors such as televisions, measuring devices, information terminal devices, etc., but due to its own weight and size, It could not actively respond to the demand for miniaturization and weight reduction.

이러한 음극선관을 대체하기 위해서 소형, 경량화 및 저소비전력 등과 같은 장점을 가지고 있으며, LCD 패널의 내부에 주입된 액정의 전기, 광학적 성질을 이용하여 정보를 표시하는 액정표시장치가 활발하게 개발되어 왔고 최근에는 평판 표시장치로서의 역할을 충분히 수행할 수 있을 정도로 기능이 개선되어 여러 시스템의 모니터뿐만 아니라 텔레비전의 브라운관으로도 사용되고 있다.In order to replace the cathode ray tube, it has advantages such as small size, light weight, low power consumption, and the like, and a liquid crystal display device that displays information by using the electrical and optical properties of the liquid crystal injected into the LCD panel has been actively developed. The function is improved enough to perform a role as a flat panel display device, and is used as a CRT of a television as well as a monitor of various systems.

이와 같이 여러 시스템의 모니터로 사용되는 액정표시장치는 시스템, 예를 들어 컴퓨터 본체와 커넥터에 의해 연결되어 있으며, 컴퓨터 본체에서 출력된 화상신호(R,G,B), 클럭신호, 동기신호 및 전원신호 등을 입력받아 소정의 정보를 표시한다.As such, a liquid crystal display device used as a monitor of various systems is connected to a system, for example, a computer main body and a connector, and image signals (R, G, B), clock signals, synchronization signals, and power supplies output from the computer main body. Receives a signal or the like and displays predetermined information.

여기서, 컴퓨터 본체에서 액정표시장치로 제공되는 화상신호, 클록신호 및 동기신호 등은 약 3.3V 이상의 전압을 갖는데, 액정표시장치의 사이즈가 커지고 해상도가 높아질수록 화상신호, 클럭신호 및 동기신호들의 전압이 높아지면 전자파 및 잡음 등이 많이 발생되므로 액정표시장치의 화질이 저하된다.Here, the image signal, the clock signal, and the synchronization signal provided from the computer main body to the liquid crystal display device have a voltage of about 3.3 V or more. As the size of the liquid crystal display device increases and the resolution increases, the voltage of the image signal, the clock signal, and the synchronization signal increases. If this increases, a lot of electromagnetic waves and noise are generated, and thus the image quality of the liquid crystal display is deteriorated.

이로 인해 최근에는 화상신호, 클럭신호 및 동기신호들 등을 디지털화하고 압축하며 전압을 1V이하로 낮추는 LVDS 송신부를 컴퓨터 본체에 내장시켜 저전압 차동신호로 액정표시장치에 전송하고, 액정표시장치의 인쇄회로기판에는 전송된 저전압 차동신호를 원래의 상태로 복원하는 LVDS 수신부를 실장함으로써, 전자파 및 잡음의 방출을 억제하고 있다.For this reason, recently, an LVDS transmitter which digitizes and compresses an image signal, a clock signal, and a synchronization signal, and lowers a voltage below 1 V is incorporated in a computer main body to transmit a low voltage differential signal to a liquid crystal display, and a printed circuit of the liquid crystal display device. The board is equipped with an LVDS receiver for restoring the transmitted low voltage differential signal to its original state, thereby suppressing the emission of electromagnetic waves and noise.

도 1에 도시된 바와 같이 저전압 차동 신호의 특성상 컴퓨터 본체와 액정표시장치를 전기적으로 연결하는 플렉시블 프린티드 서킷 케이블(2)의 신호선, 플렉 시블 프린티드 서킷 케이블(2)과 연결되는 커넥터(10)의 핀(20) 및 커넥터(10)와 LVDS 수신부(50)를 전기적으로 연결하는 인쇄회로기판(1)의 신호선들(30)은 보통 2개가 하나의 조를 이루어 저전압 차동신호를 LVDS 수신부(50)까지 전송한다.As shown in FIG. 1, a connector 10 connected to a signal line of a flexible printed circuit cable 2 and a flexible printed circuit cable 2 that electrically connect the computer body and the liquid crystal display device due to characteristics of a low voltage differential signal. The signal lines 30 of the printed circuit board 1 electrically connecting the pins 20 and the connector 10 and the LVDS receiver 50 of the LDS receiver 50 usually have a pair of low voltage differential signals. To send).

그리고, 도 1에 도시된 바와 같이 저전압 차동 신호를 안정화시키기 위해서 커넥터와 LVDS 수신부(50) 사이에 형성된 신호선(30)의 길이는 가능한 한 짧게 형성하고, 2개가 한 조를 이루는 신호선(30) 사이에 소정의 저항, 예를 들어 100Ω정도를 갖는 저항소자(40)를 실장하며, 잡음 및 전자파에 취약한 LVDS 수신부(50)의 주위에는 많은 개수의 캐패시턴스(60)를 실장한다.In addition, as shown in FIG. 1, the length of the signal line 30 formed between the connector and the LVDS receiver 50 is as short as possible to stabilize the low-voltage differential signal, and between the two signal lines 30 in a pair. A resistor 40 having a predetermined resistance, for example, about 100 mA is mounted on the capacitor, and a large number of capacitances 60 are mounted around the LVDS receiver 50 vulnerable to noise and electromagnetic waves.

그러나, 상술한 바와 같이 커넥터와 LVDS 수신부의 사이의 거리가 짧고 잡음에 민감한 LVDS 수신부 주위에 많은 개수의 캐패시터가 설치되므로, 커넥터와 LVDS 수신부 사이의 실장면적이 좁아 2개의 신호선 사이에 저항소자를 실장할 공간을 확보하는데 많은 어려움이 있어 인쇄회로기판의 설계가 어려운 문제점이 있다.However, as described above, since the distance between the connector and the LVDS receiver is short and a large number of capacitors are installed around the noise sensitive LVDS receiver, the mounting area between the connector and the LVDS receiver is narrow, so that a resistance element is mounted between the two signal lines. There is a lot of difficulty in securing a space to do the design of the printed circuit board has a problem that is difficult.

또한, 별도의 부품화된 저항 소자를 인쇄회로기판에 실장해야 하기 때문에 액정표시장치의 조립공정수 및 제조 비용이 상승된다.In addition, since a separate componentized resistance element must be mounted on a printed circuit board, the number of assembly processes and manufacturing cost of the liquid crystal display device are increased.

따라서, 본 발명의 목적은 상기와 같은 문제점을 감안하여 안출된 것으로써, 커넥터와 일체로 터미널 저항을 형성하여 인쇄회로기판의 실장면적을 증대시키므로 인쇄회로기판의 설계를 단순화시키고, 액정표시장치의 조립공정 및 제조 비용을 절감하는데 있다.Accordingly, an object of the present invention has been made in view of the above-mentioned problems, thereby increasing the mounting area of a printed circuit board by forming a terminal resistor integrally with a connector, thereby simplifying the design of the printed circuit board, It is to reduce the assembly process and manufacturing cost.

본 발명의 다른 목적은 저전압 차동신호가 입력되는 핀 주위의 그라운드를 강화하여 보다 안정된 저전압 차동신호를 얻는데 있다.Another object of the present invention is to obtain a more stable low voltage differential signal by strengthening the ground around the pin to which the low voltage differential signal is input.

본 발명의 또 다른 목적은 다음의 상세한 설명과 첨부된 도면으로부터 보다 명확해 질 것이다.Still 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 전원신호가 입력되는 저전압 차동 신호의 특성상 2개의 구동신호 입력핀이 짝을 이루고, 짝을 이루는 2개의 구동신호 입력핀 사이에 형성된 브리지를 통해 전기적으로 연결되며, 2개의 구동신호 입력핀과 브리지는 입력된 저전압 차동신호를 안정화시키기 위해 소정 오옴의 자체 저항을 갖는다.In order to achieve the above object, in the present invention, two drive signal input pins are paired due to the characteristics of the low voltage differential signal into which the power signal is input, and are electrically connected through a bridge formed between the paired drive signal input pins. The two drive signal input pins and the bridge have a predetermined ohmic resistance to stabilize the input low voltage differential signal.

이하, 본 발명에 의한 LVDS 방식의 신호를 입력하는 커넥터의 구조를 첨부된 도면 도 2내지 도 3을 참조하여 설명하면 다음과 같다.Hereinafter, a structure of a connector for inputting an LVDS signal according to the present invention will be described with reference to FIGS. 2 to 3.

도 2에 도시된 바와 같이 액정표시장치의 인쇄회로기판(100)에는 플렉시블 프린티드 서킷 케이블(102)에 의해 시스템의 본체와 연결되는 커넥터(110), 커넥터(110)와 소정간격 이격되며 시스템의 본체로부터 전송된 저전압 차동 신호를 복원하는 LVDS 수신부(150), LVDS 수신부(150)의 주위에 복수개 설치되어 저전압 차동신호를 안정화시키는 캐피시턴스(160) 및 복수개의 부품이 실장된다.As shown in FIG. 2, the printed circuit board 100 of the liquid crystal display device is spaced apart from the connector 110 and the connector 110 to be connected to the main body of the system by a flexible printed circuit cable 102. A plurality of LVDS receiver 150 for restoring the low voltage differential signal transmitted from the main body, a capacitance 160 for stabilizing the low voltage differential signal and a plurality of components are mounted around the LVDS receiver 150.

그리고, 커넥터(110)와 LVDS 수신부(150) 사이에는 신호선들(130)이 형성되는데, 저전압 차동신호의 특성상 2개의 신호선들(130)이 하나의 짝을 이루어 커넥터(50)로부터 입력된 저전압 차동신호를 LVDS 수신부(50)로 전송한다.Signal lines 130 are formed between the connector 110 and the LVDS receiver 150. Due to the characteristics of the low voltage differential signal, two signal lines 130 are paired to form a low voltage differential input from the connector 50. The signal is transmitted to the LVDS receiver 50.

여기서, 본 발명의 중요한 특징이 있는 커넥터에 대해 도 3을 참조하여 좀더 상세히 설명하면 다음과 같다.Herein, a connector having important features of the present invention will be described in more detail with reference to FIG. 3.

도 3에 도시된 바와 같이 커넥터(110)는 메탈 재질의 박판이 소정 크기로 절단, 절곡 및 펀칭공정을 통하여 제작된 직사각형 형상의 메탈 커버(111)를 구비하며, 메탈커버(111)의 폭방향 측면에는 인슐레이터(115)를 삽입하기 위한 수납공간(113)이 메탈커버(111)의 일측면으로부터 타측면까지 관통 형성된다.As shown in FIG. 3, the connector 110 includes a rectangular metal cover 111 formed by cutting, bending and punching a thin metal plate into a predetermined size, and has a width direction of the metal cover 111. In the side surface, an accommodating space 113 for inserting the insulator 115 penetrates from one side of the metal cover 111 to the other side thereof.

그리고, 수납공간(113)에 삽입되는 인슐레이터(115)는 메탈 커버(115)와 대응되는 직사각형 형상으로, 플렉시블 프린티드 서킷 케이블(102)과 마주보는 폭방향 일측면은 다른 커넥터가 삽입될 수 있도록 LVDS 수신부(150) 쪽으로 소정깊이의 커넥터 삽입홈(117)이 형성된다.In addition, the insulator 115 inserted into the storage space 113 has a rectangular shape corresponding to the metal cover 115, and one side of the width direction facing the flexible printed circuit cable 102 may be inserted into another connector. A connector insertion groove 117 of a predetermined depth is formed toward the LVDS receiver 150.

또한, 인슐레이터(115)의 폭방향 일측면과 타측면에는 복수개의 핀들(120)이 설치되는데, 핀들(120)은 인슐레이터(115)의 폭방향 일측면으로부터 타측면까지 관통하며 인슐레이터(115)의 길이방향을 따라 일렬로 배열된다.In addition, a plurality of fins 120 are installed on one side and the other side of the insulator 115 in a width direction, and the pins 120 penetrate from one side of the insulator 115 to the other side of the insulator 115 and are formed on the other side of the insulator 115. It is arranged in a line along the longitudinal direction.

여기서, 인슐레이터(115)를 기준으로 인슐레이터(115)의 폭방향 일측면으로 돌출된 핀들은 플렉시블 프린티드 서킷 케이블(102)과 연결되어 저전압 차동 신호로 변조된 각종 신호를 입력하고, 인슐레이터(115)의 폭방향 타측면으로 돌출된 핀들은 도 2에 도시된 바와 같이 인쇄회로기판(100)에 형성된 신호선들(130)과 솔더링되어 입력된 각종신호들을 LVDS 수신부 쪽으로 출력한다.Here, the pins protruding to one side in the width direction of the insulator 115 based on the insulator 115 are connected to the flexible printed circuit cable 102 to input various signals modulated by low voltage differential signals, and the insulator 115 As shown in FIG. 2, the pins protruding to the other side in the width direction are soldered to the signal lines 130 formed on the printed circuit board 100 to output various signals inputted to the LVDS receiver.

보통, 인슐레이터(115)의 길이방향을 따라 20개 정도의 핀들(120)이 설치되는데, 20개 정도의 핀들(120) 중 2개는 전원신호가 입력되는 전원(Vcc) 입력핀(121)이고, 8개의 핀은 그라운드 핀(123)이며, 나머지 10개의 핀은 저전압 차동 신호로 변조된 각종 구동신호, 예를 들어 화상신호, 클럭 신호 및 동기신호 등을 입력하는 구동신호 입력핀(125)이다.Usually, about 20 pins 120 are installed along the longitudinal direction of the insulator 115, and two of the 20 pins 120 are power (Vcc) input pins 121 to which a power signal is input. The eight pins are the ground pins 123, and the remaining ten pins are the drive signal input pins 125 for inputting various drive signals modulated by low voltage differential signals, for example, image signals, clock signals, and synchronization signals. .

이들 구동신호 입력핀들(125)은 전자파를 상쇄하기 위해 서로 인접한 2개의 구동신호 입력핀이 짝을 이루어 저전압 차동 신호로 변조된 각종 구동신호를 전송한다.
여기서, 2개의 전원 입력핀(121)은 인슐레이터(115)의 길이 방향의 일측부에 형성되고, 그라운드 핀(123)들은 전원 입력핀(121)의 일측으로 인슐레이터(115)의 길이 방향을 따라 형성된다. 구동신호 입력핀(125)들은 양단의 그라운드 핀(123)들 사이를 제외하고, 그라운드 핀(123)들 사이에 2개의 구동신호 입력핀들이 형성된다.즉, 그라운드 핀(123)들은 2개의 구동신호 입력핀(125)들과 교대로 형성된다.
본 발명에 따르면 인슐레이터(115)에 설치된 핀들(120) 중 그라운드 핀(123)은 전원 입력핀(121)과 구동신호 입력핀(125)의 크기보다 더 크고 두께도 더 두껍게 형성되어 전원 입력핀(121)과 구동신호 입력핀(125) 주위의 접지 특성을 향상시킨다. These drive signal input pins 125 transmit various drive signals modulated into low voltage differential signals by pairing two drive signal input pins adjacent to each other to cancel electromagnetic waves.
Here, the two power input pins 121 are formed on one side of the insulator 115 in the longitudinal direction, and the ground pins 123 are formed on one side of the power input pin 121 along the longitudinal direction of the insulator 115. do. Two driving signal input pins are formed between the ground pins 123 except for the ground pins 123 at both ends of the driving signal input pins 125. The signal input pins 125 are alternately formed.
According to the present invention, the ground pin 123 of the pins 120 installed in the insulator 115 is larger than the size of the power input pin 121 and the drive signal input pin 125 and is formed to have a thicker thickness, thereby providing a power input pin ( 121 and the ground characteristics around the driving signal input pin 125 are improved.

따라서, 전자파의 발생 및 신호의 왜곡을 최소화하기 위해 저전압 차동 신호로 변조된 전원신호 및 각종 구동신호가 종래에 비해 더욱 안정화된다.Therefore, in order to minimize the generation of electromagnetic waves and distortion of the signal, the power signal and various driving signals modulated by the low voltage differential signal are more stabilized than in the related art.

한편, 인쇄회로기판(100)의 설계를 용이하게 하기 위해서 그라운드 핀(123)들이 형성되고, 그라운드 핀(123)들 사이에는 구동신호 입력부가 형성된다. 구동신호 입력부는 2개의 구동신호 입력핀들(125)과, 입력핀들(125)을 사이에 형성되어 입력핀들(125)를 연결시키는 브리지(126)를 포함한다. 즉, 그라운드 핀(123)들 사이에는 구동신호 입력부가 형성되고, 상기 구동신호 입력부는 그라운드 핀들 사이에 형성되는 2개의 구동신호 입력핀(125)과 브리지(126)를 포함한다. 이러한 구동신호 입력부는 구동신호 입력핀(125) 및 브리지(126)를 형성하는 금속 재질에 불순물을 일정량 함유시켜 저전압 차동신호를 안정화시킬 수 있는 소정 오옴(Ω)의 저항, 예를 들어 80Ω∼120Ω정도의 저항을 갖도록 형성한다. 가장 바람직한 구동신호 입력픽들의 저항은 100Ω이다.Meanwhile, the ground pins 123 are formed to facilitate the design of the printed circuit board 100, and a driving signal input unit is formed between the ground pins 123. The driving signal input unit includes two driving signal input pins 125 and a bridge 126 formed between the input pins 125 to connect the input pins 125. That is, a driving signal input unit is formed between the ground pins 123, and the driving signal input unit includes two driving signal input pins 125 and a bridge 126 formed between the ground pins. The driving signal input part contains a predetermined amount of impurities (eg, 80 kΩ to 120 kΩ) capable of stabilizing a low voltage differential signal by containing a certain amount of impurities in the metal forming the driving signal input pin 125 and the bridge 126. Form to have a degree of resistance. The most preferable driving signal input pick resistance is 100 kΩ.

이와 같이 구동신호 입력핀(125)들이 저전압 차동신호를 LVDS 수신부(150)로 전송하기 위해서 짝을 이루는 2개의 구동신호 입력핀들(125)이 전기적으로 연결되면, 구동신호 입력핀들(125)과 브리지(126)가 종래에서 신호선들(130) 사이에 실장되는 저항 소자 역할을 하기 때문에 구동신호 입력핀(125)으로 입력된 저전압 차동 신호를 안정화시켜 신호선(130)으로 출력시킬 수 있다.As such, when the two driving signal input pins 125 are electrically connected to each other to transmit the low voltage differential signal to the LVDS receiver 150, the driving signal input pins 125 and the bridge are electrically connected to the driving signal input pins 125. Since 126 serves as a resistor device mounted between the signal lines 130, the low voltage differential signal input to the driving signal input pin 125 may be stabilized and output to the signal line 130.

또한, 커넥터(110)와 LVDS 수신부(150) 사이의 좁은 공간에 별도의 부품화된 저항 소자를 실장하지 않아도 되기 때문에 인쇄회로기판(100)의 실장면적이 증대되고 인쇄회로기판(100)의 설계가 용이해진다.In addition, since a separate componentized resistor does not need to be mounted in a narrow space between the connector 110 and the LVDS receiver 150, the mounting area of the printed circuit board 100 is increased and the design of the printed circuit board 100 is increased. Becomes easy.

이상에서 설명한 바와 같이 본 발명은 커넥터에 형성된 복수개의 핀들 중 그라운드 핀의 크기와 구께를 다른 핀들, 즉 전원 입력핀들과 구동신호 입력핀들보다 크고 두껍게 형성하여 전원 입력핀들과 구동신호 입력핀들 주위의 그라운드를 강화함으로써, 저전압 차동 신호로 변조된 각종 구동신호를 안정화시킨다.
또한, 2개의 구동신호 입력핀과 2개의 구동신호 입력핀을 연결하는 브리지를 포함하는 구동신호 입력부들이 입력되는 저전압 차동신호를 안정화 시킬 수 있는 소정 오옴(Ω)의 저항을 갖도록 형성함으로써, 인쇄회로기판의 실장면적을 증대시켜 인쇄회로기판의 설계를 단순화시킬 수 있다. As described above, in the present invention, the size and thickness of the ground pins of the plurality of pins formed in the connector are larger and thicker than other pins, that is, the power input pins and the driving signal input pins, so that the ground around the power input pins and the driving signal input pins is formed. By stabilizing, various drive signals modulated by the low voltage differential signal are stabilized.
In addition, the driving signal input parts including a bridge connecting the two driving signal input pins and the two driving signal input pins are formed to have a resistance of a predetermined ohm (Ω) to stabilize the low voltage differential signal inputted therein, thereby printing By increasing the mounting area of the circuit board, the design of the printed circuit board can be simplified.
