녹색 텍스트 모드(Text Mode) 장치Green Text Mode Device

제 1 도는 본 고안 장치의 회로도.1 is a circuit diagram of the device of the present invention.

제 2 도는 종래 녹색 텍스트 모드장치의 회로도.2 is a circuit diagram of a conventional green text mode device.

본 고안은 칼라 모니터의 녹색문자 전용장치에 관한 것으로서 특히 음극선관의 적녹청색 영상출력부의 공급 전원(B+)에 스위칭부를 설치하여 녹색문자전용 표시를 할 수 있는 녹색 텍스트 모드(Text Mode) 장치에 관한 것이다.The present invention relates to a green character dedicated device of a color monitor. Especially, a green text mode device capable of displaying a green character only by installing a switching unit at a power supply (B + ) of a red-green-blue image output part of a cathode ray tube. It is about.

종래의 녹색텍스트모드 장치는 제 2 도에서 도시된 바와같이 음극선관(30)에 적, 녹, 청색의 영상신호를 공급하는 동일한 구성의 적, 녹, 청색 영상출력부(31, 32, 33)의 각 제어전원입력(X1, X2, X3)중 제어 전원 입력(X1, X3)을 스위치(SW1)의 가동단자(a)에 연결하고 제어전원입력(X2)은 스위치(SW1)의 고정단자(b)를 통하여 전원(B+)에 연결한 구성으로서 스위치(SW1)의 가동단자(a)를 고정단자(b)에 접속시켜 스위치(SW1)를 온하면 전원(B+)이 적, 녹, 청색 영상출력부(31, 32, 33)의 각 제어 전원입력(X1, X2, X3)에 공급되어 적, 녹, 청색 영상출력부(31, 32, 33)가 정상 작동되어 칼라 모니터의 음극선관(30)의 화면에서는 일반 16색상의 표시된다. 즉, 적, 녹, 청색의 영상출력부(31, 32, 33)의 구성은 동일한 것이므로 도면의 간편상 제 2 도에서는 녹색 영상출력부(32)의 상세 구성이 도시되어 있다.In the conventional green text mode device, the red, green, and blue image output units 31, 32, and 33 having the same configuration for supplying red, green, and blue image signals to the cathode ray tube 30, as shown in FIG. each control power input (X 1, X 2, X 3) of the control power input (X 1, X 3) connected to the movable terminal (a) of the switch (SW 1) and to control the power input (X 2) will switch the by connecting the movable terminal (a) of the switch (SW 1) a configuration in which through the fixed terminal (b) connected to a power source (b +) of (SW 1) to the fixed terminal (b) when turning on the switch (SW 1) Power (B + ) is supplied to each of the control power inputs (X 1 , X 2 , X 3 ) of the red, green, and blue image output units 31, 32, and 33 so that the red, green, and blue image output units 31, 32 and 33 are normally operated to display the normal 16 colors on the screen of the cathode ray tube 30 of the color monitor. That is, since the configurations of the red, green, and blue image output units 31, 32, and 33 are the same, the detailed configuration of the green image output unit 32 is shown in FIG.

이러한 구성을 예로 들어 설명하면 제어 전원입력(X2)이 인가되지 않은 상태에서는 가변저항(VRg)에 의하여 결정된 트랜지스터(TR1)의 에미터 전위가 높게 되어 트랜지스터(TR1)는 오프상태가 되므로 음극선관(30)의 캐소우드(GK)에는 전원(B+)이 인가되므로 녹색영상출력부(32)의 작동이 중단되고 이에 따라서 입력된 녹색 신호(GR1)는 음극선관(30)의 캐소우드(GK)에 전달되지 않는다.Taking this configuration as an example, when the control power input X 2 is not applied, the emitter potential of the transistor TR 1 determined by the variable resistor VRg becomes high, and the transistor TR 1 is turned off. Since the power B + is applied to the cathode GK of the cathode ray tube 30, the operation of the green image output unit 32 is stopped, and thus the input green signal GR 1 is applied to the cathode of the cathode ray tube 30. It is not delivered to the wood (GK).

전원(B+)이 제어전원 입력(X2)에 인가되면 트랜지스터(TR1)는 온 되도록 저항(R3)의 값을 정해 놓았으므로 트랜지스터(TR1)는 온 되고 이에 따라서 녹색 신호(GR1)는 음극선관(30)의 캐소우드(GK)에 전달된다. 이러한 구성은 적, 청색 영상 출력부(31, 33)에서도 동일한 작용이 일어 난다. 즉 전원(B+)이 각각의 제어전원 입력(X1, X3)에 입력되면 입력되는 적, 청 신호(RE1, BL1)가 음극선관의 캐소우드(RK, BK)에 인가된다.When the power supply B + is applied to the control power input (X 2 ), the transistor TR 1 is set so that the value of the resistor R 3 is turned on, so the transistor TR 1 is turned on and thus the green signal GR 1. ) Is delivered to the cathode GK of the cathode ray tube 30. This configuration is similar to the red and blue image output units 31 and 33. That is, when the power source B + is input to each of the control power inputs X 1 and X 3 , the red and blue signals RE 1 and BL 1 which are input are applied to the cathodes RK and BK of the cathode ray tube.

만약 스위치(SW1)를 오프하면 전원(B+)은 제어전원 입력(X1, X3)에 입력되지 않아 적, 청색 영상 출력부(31, 33)이 작동되지 않음과 동시에 전원(B+)이 제어전원 입력(X2)에 인가되는 녹색 영상 출력부(32)가 작동되어 음극선관(30)의 화면에는 녹색만 표시되는 것이나 이러한 종래의 장치는 녹색입력신호(GR1)가 입력되어야만 출력이 나타나도록 되고 적, 청색의 입력신호(RE1, BL1)만 입력되는 경우에는 음극선관(30)의 화면에 출력이 나타나지 않게 되는 단점이 있다.If the switch (SW 1 ) is turned off, the power (B + ) is not input to the control power input (X 1 , X 3 ), so the red and blue image output parts (31, 33) do not operate and at the same time the power (B +) ) Is applied to the control power input (X 2 ) to operate the green image output unit 32 so that only the green is displayed on the screen of the cathode ray tube 30. However, in the conventional apparatus, the green input signal GR 1 must be input. When the output appears and only the red and blue input signals RE 1 and BL 1 are input, there is a disadvantage in that the output does not appear on the screen of the cathode ray tube 30.

본 고안은 이러한 종래의 단점을 해결하기 위하여 음극선관의 적, 녹, 청색 영상 출력부의 공급전원(B+)에 스위칭부를 설치하여 녹색테스트 모드인 경우에도 적, 녹, 청색 입력신호(RE1, GR1, BL1)중 어느 하나의 신호만 입력되어도 음극선관(30)의 화면에 녹색영상이 표시되게 할 수 있는 녹색 텍스트 모드 장치를 제공하는 것을 목적으로 하며, 이하 첨부된 도면을 참조하면서 본 고안의 구성 및 작용효과를 설명하면 다음과 같다.The present invention provides a red, green, blue input signal (RE 1 , even in the green test mode) by installing a switching unit in the supply power (B + ) of the red, green, blue image output unit of the cathode ray tube to solve this conventional disadvantage. It is an object of the present invention to provide a green text mode device capable of displaying a green image on the screen of the cathode ray tube 30 even when only one signal of GR 1 and BL 1 is input. The construction and effect of the design will be described as follows.

제 1 도를 참조하면 본 고안 장치는, 적, 녹, 청색 영상 출력부(1, 2, 3)가 음극선관(4)에 연결되며 전원(B+)이 적, 청색 영상출력부(1, 3)의 제어 입력(X1, X3)에 인가되는 것을 스위칭하는 녹색 텍스트 모드 장치에 있어서, 전원(B+)은 스위치(SW1)의 가동자(C1)에 연결함과 동시에 녹색 영상 출력부(2)의 제어입력(X2)에 연결하고, 스위치(SW1)의 고정자(A1)은 적, 청색 영상 출력부(1, 3)의 제어입력(X1, X3)에 연결하며, 스위치(SW1)의 고정자(B1)는 적, 청색 입력(RE1, BL1)에 콜렉터가 각각 연결된 트랜지스터(Q2, Q3)의 베이스에 연결하고, 스위치(SW1)에 연동되는 스위치(SW2)의 가동자(C2)접지에 연결하되 고정자(b2)는 저항(R6)을 통하여 녹색 영상 출력부(2)내의 트랜지스터(Q1)의 에미터에 연결하며, 트랜지스터(Q2, Q3)의 에미터는 녹색입력(GR1)에 연결하여된 구성으로서 이러한 본 고안 장치의 작용 효과는, 녹색 텍스트-칼라 모드 회로에서 전원단자(B+)를 통해 전원이 인가되고, 적, 녹, 청신호 단자(RE1, GR1, RL1)를 통해 해당 신호가 인가될때 연동되는 스위치(SW1-SW2)를 그의 고정단자(A1-A2)에 접속하면 공급 전원(B+)이 적, 녹, 청의 영상출력회로(1, 2, 3)에 가해지므로 트랜지스터(Q2, Q3)는 동작하지 않고 적, 녹, 청의 영상출력회로가 동작하므로 일반 16칼라가 전시된다.Referring to FIG. 1, the device according to the present invention includes a red, green, and blue image output units 1, 2, and 3 connected to the cathode ray tube 4, and a power source B + is a red and blue image output unit 1, In the green text mode device which switches what is applied to the control inputs (X 1 , X 3 ) of 3 ), the power source B + is connected to the mover C 1 of the switch SW 1 and at the same time the green image. To the control input (X 2 ) of the output unit 2, the stator (A 1 ) of the switch (SW 1 ) is connected to the control input (X 1 , X 3 ) of the red, blue image output unit (1, 3) connection, and switch the stator (B 1) is small, the blue (RE 1, BL 1) the collector respectively connected to the transistors (Q 2, Q 3) connected to the base of a, and the switch (SW 1) of the (SW 1) but connected to the movable element (C 2) the ground of the switch (SW 2) that is interlocked with the stator (b 2) is connected to the emitter of the transistor (Q 1) in the green image output unit (2) via the resistor (R 6) and a green emitter input of the transistor (Q 2, Q 3) ( GR 1) Action and effect of the present design the device as a configuration to connect the green text - the power supply through the power supply terminal (B +) from the color mode circuit is applied, the red, green, and green light terminals (RE 1, GR 1, RL 1) When the switch (SW 1 -SW 2 ) interlocked when the corresponding signal is applied to its fixed terminals (A 1 -A 2 ), the power supply (B + ) is red, green, and blue video output circuits (1, 2) And 3), transistors Q 2 and Q 3 do not operate, and red, green, and blue image output circuits operate, and thus 16 general colors are displayed.

이와같은 상태에서 상기 스위치(SW1-SW2)를 그의 고정단자(B1-B2)에 접속하면 적, 청 영상 출력회로(1,3)에는 공급전원(B+)이 가해지지 않으므로 동작하지 않고 녹색 영상 출력 회로(2)에만 가해지므로 녹색영상 출력회로가 동작되어 녹색(Green)만 전시되는데 이때에 공급전원(B+)이 트랜지스터(Q2, Q3)의 베이스에 인가되므로 트랜지스터(Q2, Q3)가 동작이 되어 적, 청(RE, BL)의 신호가 녹색 영상 출력 트랜지스터(Q1)의 베이스로 인입되므로 입력신호가 녹색(GR)뿐만아닌 적(RE), 청(BL)색이 입력되더라도 녹색(GR)이 전시되게 된다.In this state, when the switches SW 1 to SW 2 are connected to the fixed terminals B 1 to B 2 , the power supply B + is not applied to the red and blue image output circuits 1 and 3. Instead of being applied only to the green image output circuit 2, the green image output circuit is operated so that only green is displayed. At this time, the power supply B + is applied to the bases of the transistors Q 2 and Q 3 . Q 2 , Q 3 ) is activated, and the red and blue signals (RE, BL) are introduced into the base of the green image output transistor Q 1 , so the input signals are not only green (GR) but also red (RE) and blue ( Even if BL) color is inputted, green GR is displayed.

또한 이때에 적, 녹, 청색(RE, GR, BL)이 동시에 입력될때에는 녹색 영상출력 트랜지스터(Q1)의 에미터에 있는 저항(R6)이 접지되므로 출력의 크기를 보정할 수가 있다.At this time, when red, green, and blue (RE, GR, BL) are input at the same time, the resistance R 6 of the emitter of the green image output transistor Q 1 is grounded, and thus the output size can be corrected.

이상에서 설명된 바와같이 본 고안 장치에 의하면 녹색 전용 텍스트 모드시에도 적, 녹, 청색 입력(RE1, GR1, BL1)중 어느 하나의 신호가 입력되어도 녹색 영상 출력부가 작동되어 화면에 녹색의 영상을 표시할 수 있는 것이다.As described above, according to the device of the present invention, even when one of the red, green, and blue input signals (RE 1 , GR 1 , BL 1 ) is input even in the green-only text mode, the green image output unit operates to display the green color on the screen. It is possible to display the image of.
