일반적으로 액정표시소자는 소정의 문자, 숫자 및 기호 등을 표시하는 것으로서 다수의 셀을 일성간격을 유지하면서 상하좌우로 배열설치하고, 각각의 셀에 전원을 인가하여 동작시키고 있다.In general, a liquid crystal display device displays predetermined letters, numbers, symbols, and the like, and operates a plurality of cells arranged up, down, left, and right while maintaining a uniform interval, and applying power to each cell.
이러한 액성표시소자를 구동시키기 위한 구동장치는 액정표시소자를 만드는 유리기판에 일체로 형성하는 것으로서 TFT 액정표시소자 및 SND 액정표시소자가 있다.The driving device for driving such a liquid crystal display device is formed integrally with a glass substrate for making a liquid crystal display device, and includes a TFT liquid crystal display device and an SND liquid crystal display device.
그러나 TFT 액정표시소자는 유리기한에 트렌지스터를 증착하여 형성해야 되는 것으로서 제조가 어려운 문제점이 있었고, SND 액정표시소자는 제조가 비교적 간단한 반면에 크로스 토키(cross talk) 현상이 발생하기 쉬운 문제점이 있었다.However, the TFT liquid crystal display device has a problem in that it is difficult to manufacture because it is formed by depositing a transistor in the expiration time, and the SND liquid crystal display device has a problem that a cross talk phenomenon tends to occur while being relatively simple to manufacture.
본 고안은 상기와 같은 종래의 제반 문제점들을 해결하기 위하여 안출한 것으로서, 다이오드 및 저항을 이용하여 액정표시소자의 구동장치를 구성함으로써 제조가 매우 간단하고, 크로스 토크현상이 발생하지 않는 액성표시소자의 구동회로를 제공하는 데 그 목적이 있다.The present invention has been made to solve the above-mentioned problems, and the liquid crystal display device of the liquid crystal display device which is very simple to manufacture and does not generate cross talk phenomenon by configuring the driving device of the liquid crystal display device using a diode and a resistor. The purpose is to provide a driving circuit.
이러한 목적을 가지는 본 고안의 액정표시소자의 구동회로는 역방향 다이오드를 통해 소거단자에 접속된가 아울러 접지 콘덴서에 접속된 셀과, 역방향 다이오드 및 순방향 다이오드를 순차적으로 통해 상기 셀에 접속된 열단자와, 상기 역방향 다이오드 및 순방향 다이오드의 접속점과 행단자의 사이에 접속된 저항으로 구성되어 각각의 셀에 원하는 전압을 인가한다.The driving circuit of the liquid crystal display device of the present invention having the above object comprises a cell connected to the erasing terminal through a reverse diode and a column terminal connected to the ground capacitor, a thermal terminal connected to the cell sequentially through a reverse diode and a forward diode; It is composed of a resistor connected between the connection point of the reverse diode and the forward diode and the row terminal to apply a desired voltage to each cell.
이하 첨부된 도면을 참조하여 본 고안의 액정표시소자의 구동회로를 상세히 설명한다.Hereinafter, a driving circuit of the liquid crystal display device of the present invention will be described in detail with reference to the accompanying drawings.
제1도는 본 고안의 구동회로도로서 이에 도시된 바와 같이, 소거단자(Er)를 역방향 다이오드(D1∼D4)를 통해 셀(1∼4)에 각기 접속함과 아울러 셀(1∼4)에 접지 콘덴서(C1∼C4)를 접속하고, 열단자(ROW1, ROW2)를 역방향다이오드(D5∼D8)및 순방향 다이오드(D9∼D12)를 순차적으로 통해 셀(1∼4)에 접속함과 아울러 역방향 다이오드(D5∼D6) 및 순방향 다이오드(D9∼D12)의 접속점과 행단자(COL1,COL2)의 사이에 저항(R1∼R4)을 접속하였다.1 is a driving circuit diagram of the present invention, as shown therein, the erasing terminal Er is connected to the cells 1 to 4 through the reverse diodes D 1 to D 4, respectively, and the cells 1 to 4. The ground capacitors C 1 to C 4 are connected to each other, and the thermal terminals ROW 1 and ROW 2 are sequentially connected through the reverse diodes D 5 to D 8 and the forward diodes D 9 to D 12 . in addition, a reverse diode and also connected to ~4) (D 5 ~D 6) and a forward diode (D 9 resistance (R 1 ~R 4) between the connection point and the line terminal (COL 1, COL 2) of ~D 12) Was connected.
이와 같이 구성된 본 고안의 액정표시소자의 구동회로는 소거단자(Er)에 전원이 인가된 상태에서 열단자(ROW1, ROW12) 및 행단자(COL1, COL2)에 소정의 구동전원이 인가되면, 각각의 셀(1∼4)에는 원하는 소정의 전압이 인가되어 구동된다.The driving circuit of the liquid crystal display device according to the present invention configured as described above has predetermined driving power applied to the column terminals ROW 1 and ROW 12 and the row terminals COL 1 and COL 2 while power is applied to the erasing terminal Er. When applied, the desired predetermined voltage is applied to each of the cells 1 to 4 to be driven.
예를 들면, 셀(1)에는 3V를 인가하고, 셀(2)에는 5V를 인가하며, 셀(3, 4)에는 0V를 인가한다고 가정한 경우에 소거단자(Er)에는 7V를 인가한 상태에서 열단자(ROW1, ROW2)에 각기 3V 및 5V를 인가하고, 행단자(COL1, COL2)에 각기 7V 및 OV를 인가하면, 역방향 다이오드(D5) 밋 순방향 다이오드(L)의 접속점(A)과 역방향 다이오드(D6) 및 순방향 다이오드(D10)의 접속점(B)의 전압은 각기 3V 및 5V가 되므로 셀(1), (2)에는 각기 3V 및 5V가 인가되고, 행단자(COL2)에 인가된 OV에 의해 역방향 다이오드(D7) 및 순방향 다이오드(D11)의 접속점(C)과 역방향 다이오드(D8) 및 순방향 다이오드(D11)의 점속점(D)의 전압은 모두 0V가 되어 셀(3), (4)에는 모두 0V가 인가된다.For example, assuming that 3V is applied to the cell 1, 5V is applied to the cell 2, and 0V is applied to the cells 3 and 4, 7V is applied to the erase terminal Er. If 3V and 5V are respectively applied to the thermal terminals ROW 1 and ROW 2 , and 7V and OV are respectively applied to the row terminals COL 1 and COL 2 , the reverse diode (D 5 ) is applied to the mid forward diode (L). Since the voltages of the connection point A and the connection point B of the reverse diode D 6 and the forward diode D 10 become 3V and 5V, respectively, 3V and 5V are applied to the cells 1 and 2, respectively. a reverse diode (D 7) and a forward diode (D 11) connecting point (C) and a reverse diode (D 8) and a forward diode (D 11) that sokjeom (D) of the by an authorized OV to the terminal (COL 2) The voltage is all 0V, and 0V is applied to all of the cells 3 and 4.
이와 같은 상태에서 행단자(COL1), (COL2)에 각기 W 및 7V를 인가하게 되어도 콘덴서(C1∼C4)에 의해 셀(1), (2)에는 처음에 인가되었던 3V 및 5V가 그대로 인가되고, 셀(3), (4)에는 각기 3V 및 5V가 인가되는 것으로서 소거단자(Er)에 인가되는 전원을 차단한 경뉴에 셀(1∼4)에는 모두 전원이 인가되지 않게 된다.In this state, even though W and 7V are respectively applied to the cutting terminals COL 1 and COL 2 , 3V and 5V initially applied to the cells 1 and 2 by the capacitors C 1 to C 4 . Is applied as it is, and 3V and 5V are applied to the cells 3 and 4, respectively, so that power is not applied to all of the cells 1 to 4 when the power applied to the erase terminal Er is cut off. .
이상에서와 같이 본 고안은 다이오드 및 저항만을 이용하여 액정표시소자를 이루는 각각의 셀에 소정의 전압을 인가하여 구동시키는 것으로서 유리기판에 다이오드 및 저항을 증착하면 되어 패턴의 증착시 에칭공정이 간편함은 물론 액정표시소자의 상부 유리기판에만 형성하면 되어 하부 유리기판과의 일라이닝(aligning) 공정이 필요 없으므로 제조가 매우 간단하고, 또한 크로스 토크현상이 발생하지 않으며, 콘덴서에 의해 전압이 유지되어 메모리 소자로도 사용할 수 있는 등의 효과가 있다.As described above, the present invention is driven by applying a predetermined voltage to each cell constituting the liquid crystal display using only a diode and a resistor. The diode and the resistor are deposited on a glass substrate, so that the etching process is simple when the pattern is deposited. Of course, it is necessary to form only on the upper glass substrate of the liquid crystal display device, so that there is no need for the alignment process with the lower glass substrate, so manufacturing is very simple and cross talk phenomenon does not occur, and the voltage is maintained by the capacitor so that the memory element It can also be used as an effect.
