본 발명은 이동통신단말기의 LCD모듈장치에 관한 것으로, 특히 폴더형 이동 통신단말기의 메인 PCB와 이 메인 PCB에 연결되는 LCD모듈장치내에 직렬신호 변환부를 각각 구비하여 전송신호들을 데이터와 클럭신호로 분리복원하여 처리하는 이동통신단말기의 LCD모듈장치에 관한것이다.The present invention relates to an LCD module device of a mobile communication terminal, and in particular, a serial signal conversion unit is provided in the main PCB of the clamshell mobile communication terminal and the LCD module device connected to the main PCB to separate the transmission signals into data and clock signals. The present invention relates to an LCD module device of a mobile communication terminal for restoring and processing.

일반적으로 LCD(liquid cristal display)는 CRT(cathod ray tube)와는 달리 자기 발광성이 없어 후광이 필요하지만 동작전압이 낮아 소비전력이 적은 평판 디스플레이의 일종이다. 근년에 널리 사용되고 있는 박막트랜지스터 LCD는 박막트랜지스터와 화소전극을 배열되어 있는 하판과 색상을 나타내기위한 컬러필터 및 공통 전극으로 구성된 상판, 그리고, 이 두 유리기판 사이에 채워져 있는 액정으로 구성되어 있으며, 두 유리기판의 양쪽 면에는 가시광선(자연광)을 선편광하여 주는 편광판이 각각 부착되어 있다. 이러한 방식의 LCD를 TFT-LCD라한다. 또한, 상기와 같은 액정은 분자의 배열이 어떤 방향으로 불규칙적이며 액체상태인데 다른 방향으로는 규칙적이어서 광학적으로 결정상태를 나타내므로 이방성 액체라고도 한다.In general, liquid crystal displays (LCDs), unlike CRTs (cathod ray tubes), require a backlight because they do not have self-luminous properties, but are a kind of flat panel displays that consume less power due to lower operating voltages. In recent years, the thin film transistor LCD has been widely used as a thin film transistor, a lower panel in which pixel electrodes are arranged, a top filter composed of a color filter and a common electrode for displaying colors, and a liquid crystal filled between the two glass substrates. Polarizing plates for linearly polarizing visible light (natural light) are attached to both surfaces of the two glass substrates. This type of LCD is called TFT-LCD. In addition, the liquid crystal as described above is also called anisotropic liquid because the arrangement of molecules is irregular in one direction and the liquid state, but regular in the other direction, thereby showing the optically crystalline state.

그런데, 상기와 같은 LCD모듈장치는 통상 휴대용으로 쓰일수 있어 최근에 손목시계, 컴퓨터, 이동통신단말기 등에 널리 사용되고 있다.By the way, the LCD module device as described above can be generally used as a portable, has recently been widely used in watches, computers, mobile communication terminals.

그러면, 상기와 같은 종래 LCD모듈장치가 구비된 폴더형 이동통신단말기를 도 1 및 도 2를 참고로 살펴보면, 이동통신단말기(70)의 몸체(71)에 설치되어 이동통신단말기(70)의 전체기능을 제어하는 메인 PCB(72)와, 상기 이동통신단말기(70)의 몸체 상면으로 위치하고 LCD모듈(73)을 구비하는 폴더부(74)와, 상기 메인 PCB(72)와 LCD모듈(73)사이에 연결되어 이들 사이로 전원 및 데이터신호를들을 송수신시키는 FPCB 연결부(75)를 포함한다.

한편, 상기와 같은 종래 LCD모듈장치가 구비된 폴더형 이동통신단말기의 동작을 살펴보면, 사용자가 단말기(1)의 폴더부(74)를 열고 필요한 조작을 하게되면, 단말기(1)의 내부에 구비된 메인 PCB(72)가 이를 LCD패널(76)상에 표시하게 되는데, 이때, 상기 메인 PCB(72)는 LCD패널(76)을 제어하기위하여 FPCB 연결부(75)를 통해 LCD모듈(76)로 제어신호와 데이터신호를 출력한다. 여기서, 상기 다층 예컨대, 6층(LAYER)으로 구성된 FPCB 연결부(75)는 대략ㅇ 4개의 전원 및 25 ~ 30개 정도의 신호선을 통해 신호가 공급되는데, 예컨대, ADDR/신호, WRITE/ 신호, DATA 1 ~ 16신호, INDICATOR BLUE LED 신호, Battery 전원 및 LCD전원 등이 LCD모듈(76)로 공급된다. 그러면, 상기 LCD모듈(76)은 상기 메인 PCB(72)가 다층 예컨대, 6층(LAYER)으로 구성된 FPCB 연결부(75)를 통해 제공하는 예컨대, ADDR/신호, WRITE/ 신호, DATA 1 ~ 16신호, INDICATOR BLUE LED 신호, Battery 전원 및 LCD전원 등을 수신처리하여 LCD패널(76)을 구동하므로써 폴더부(74)상에서 LCD패널(76)상에서 화상신호를 표시시킨다. On the other hand, referring to the operation of the conventional clamshell mobile communication terminal equipped with the above-described LCD module device, when the user opens the folder portion 74 of the terminal 1 and performs a necessary operation, it is provided inside the terminal 1.

There was a problem that occurred.

이에 본 발명은 상기와 같은 종래 제반 문제점을 해결하기 위해 발명된 것으로, 이동통신단말기의 메인 PCB와 LCD모듈장치사이를 연결하는 LCD FPCB의 신호선 및 전원선의 수를 상당히 줄이게 되므로 그에 따라 단말기의 제조비용을 상당히 저감시킬 수 있는 이동통신단말기의 LCD모듈장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the above conventional problems, the number of signal lines and power lines of the LCD FPCB connecting between the main PCB and the LCD module device of the mobile communication terminal significantly reduces the manufacturing cost accordingly It is an object of the present invention to provide an LCD module device of the mobile communication terminal that can significantly reduce the.

These signals are restored to the original signals, such as ADDR / signal, WRITE / signal, DATA 1 ~ 16 signal, INDICATOR BLUE LED signal, Battery power and LCD power, and output to the LCD module 3. Then, the LCD module 3 displays the image signal on the LCD panel 12 on the folder section 4 by driving the LCD panel 12 in accordance with the restored control signal.

이상 설명에서와 같이 본 발명은 폴더형 이동통신단말기의 메인 PCB와 이 메인 PCB에 연결되는 LCD모듈장치내에 직렬신호 변환부를 각각 구비하여 전송신호들을 데이터와 클럭신호로 분리복원하여 처리하므로써, 이동통신단말기의 메인 PCB와 LCD모듈장치사이를 연결하는 LCD FPCB(flexible PCB)의 신호선 및 전원선의 수를 상당히 줄이게 되므로 그에 따라 단말기의 제조비용을 상당히 저감시킬 수 있는 장점을 가지고 있다.As described above, the present invention includes a serial signal conversion unit in each of the main PCB of the clamshell mobile communication terminal and the LCD module device connected to the main PCB, thereby separately restoring and transmitting the transmission signals into data and clock signals. Since the number of signal and power lines of the LCD FPCB (flexible PCB) connecting between the main PCB of the terminal and the LCD module device is significantly reduced, the manufacturing cost of the terminal can be significantly reduced accordingly.

또한, 본 발명에 의하면, 메인 PCB로부터 송출되는 LCD 표시신호를 시리얼방식으로 변환하여 LCD FPCB 3개선을 통해 전송한 다음 이를 다시 시리얼방식으로 복원하여 LCD을 구동하게 되어 LCD FPCB의 레이어(LAYER)를 줄이게되므로 그에 따라 단말기의 설계성도 상당히 향상되는 효과도 있다.In addition, according to the present invention, by converting the LCD display signal transmitted from the main PCB to the serial method and transmitted through the three LCD FPCB improvements, and then restores it to the serial method again to drive the LCD layer (LAYER) of the LCD FPCB As a result, the design of the terminal is also significantly improved.
