본 고안은 16컬러 모니터의 모드 회로에 있어서 브라운색(Brown)을 내기 위한 것으로서, 특히 트랜지스터와 저항으로 간단한 회를 구성하여 브라운색을 재생한 모니터의 브라운색 회로에 관한 것이다.The present invention relates to a brown color in a mode circuit of a 16 color monitor, and more particularly, to a brown circuit of a monitor which reproduces brown color by forming a simple circuit using a transistor and a resistor.

종래의 컴퓨터 모니터의 16컬러 모드 회로에서 브라운색을 내기 위하여 멀티플렉스회로(IC74 LS153)를 사용하여 브라운색을 재현하였으나, 이는 패턴(PATTERN) 설계상 매우 복잡할 뿐 아니라 여러가지 매개 회로가 첨가되어 회로 구조상 복잡하고, 또한 부품의 고가로 인하여 제품 원가 상승의 요인이 되었던 것이다.The brown color is reproduced using the multiplex circuit (IC74 LS153) to produce brown color in the 16 color mode circuit of the conventional computer monitor, but this is not only very complicated in the design of the pattern (PATTERN) but also complicated in the circuit structure by adding various intermediate circuits. In addition, the high cost of parts has contributed to a rise in product cost.

본 고안은 이러한 점을 감안하여 안출된 것으로 멀티플렉스회로 대신에 트랜지스터와 몇개의 저항을 사용하여 보다 쉽게 브라운색을 제현함으로서, 제작 공정의 간편성과 제품 생산원가를 저하시키고자 하는데 본 고안의 목적이 있다.The present invention has been devised in view of this point, and it is an object of the present invention to reduce the simplicity of the manufacturing process and the cost of production by providing brown color more easily by using a transistor and a few resistors instead of the multiplex circuit. .

이하 첨부된 도면에 의해 상세히 설명하면 다음과 같다.Hereinafter, described in detail by the accompanying drawings as follows.

제2도에서와 같이 영상신호 입력단(1)의 각 영상신호(R, C, B)의 각단에 인버터회로(IC1)를 접속하고, 전원(Vcc)에 연결된 인버터회로(IC1)의 출력에 저항(R1)(R2)(R3)를 통하여 영상신호 신호 출력단(3)을 안출하며, 영상신호 입력단(1)의 인텐시티신호(I)를 인버터회로(IC2)에 연결하는 한편, 영상신호(R, G, B)가 인가된 인버터회로(IC1)의 출력단에 인버터회로(IC2)를 접속하고, 상기 인버터회로(IC2)의 출력단에는 R-C 결합회로(2)를 거쳐 트랜지스터(Q)의 베이스에 연결하며, 트랜지스터(Q)의 콜렉터에는 저항(R6)을 통하여 영상신호 출력단(3)의 G신호단에 연결하여서 된 것이다.The connection of the inverter circuit (IC 1) in Figure 2 each stage of the video signal for each video signal (R, C, B) of the input stage (1), as shown in, and the output of the inverter circuit (IC 1) connected to a power source (Vcc) The video signal signal output terminal 3 is provided through the resistors R 1 , R 2 , and R 3 , and the intensity signal I of the video signal input terminal 1 is connected to the inverter circuit IC 2 . The inverter circuit IC 2 is connected to the output terminal of the inverter circuit IC 1 to which the image signals R, G, and B are applied, and the RC coupling circuit 2 is connected to the output terminal of the inverter circuit IC 2 . It is connected to the base of the transistor Q, and the collector of the transistor Q is connected to the G signal terminal of the video signal output terminal 3 through the resistor R 6 .

상기와 같은 구성으로 이루어진 본 고안의 작용 및 효과를 설명하면 다음과 같다.Referring to the operation and effects of the present invention made of the above configuration as follows.

제1도는 본 고안 회로의 작용 설명도로서 간단히 요약하면 R신호와 B신호는 두 번 반전함으로서 원래의 신호를 재생하게 된는데 여기서 인텐시리신호(I)와의 와이어-앤드결합(A)으로 R신호 출력 및 B신호 출력에는 R + 1, B + 1신호가 된다.FIG. 1 is an explanatory view of the operation of the circuit of the present invention. In summary, the R and B signals are inverted twice to reproduce the original signal. Here, the R signal is wired and coupled with the intensity signal (A). The output and the B signal output are R + 1 and B + 1 signals.

G신호는 역시 두 번 반전으로 원래의 신호가 재생되나 인텐시티 신호(I)와 믹서 회로인 트랜지스터(Q)에 브라운색이 만들어 지게 된다.The G signal is also inverted twice so that the original signal is reproduced, but brown color is formed in the intensity signal I and the transistor Q which is a mixer circuit.

여기서 믹서 회로에 접속된 저항(R6)의 저항치가 크게 되면 적색이 많이 합성된 노란색이 나타나게 되며, 저항(R6)의 값이 적으면 적색이 적게 합성된 노란색이 나타나며, 믹서회로가 없다면 노란색만 남게된다.Here, when the resistance of the resistor R 6 connected to the mixer circuit becomes large, a large amount of red is synthesized. If the value of the resistor R 6 is small, a less red color is synthesized. Only remains

믹서회로의 트랜지스터(Q)는 R신호와 G신호가 제반전 되어 한 번 반전된 B신호와 인텐시티신호(I)가 와이어-앤드 결합(A)을 이루며 이 신호가 (R4)(R5)에 의해 크기가 분배되어 저항(R6)을 통하여 영상신호 출력단(3)의 G신호 단자와 와이어-앤드 결합(A')이 되어 출력되어 진다.In the transistor Q of the mixer circuit, the R signal and the G signal are inverted so that the B signal and the intensity signal I, which are inverted once, form a wire-end coupling (A), and this signal is formed by (R4) (R5). The size is divided and output through the resistor R 6 to the G signal terminal of the video signal output terminal 3 and the wire-end coupling A '.

제2도의 회로에서 상세히 설명하면 영상입력 신호단(1)의 R, G, B의 각 신호는 인버터회로(IC1)에서 각각2번씩 반전하여 각 저항 (R1)(R2)(R3)를 통하여 출력됨과 동시에 인버터회로(IC1)에서 한 번 반전된 R, C 신호와 인버터회로(IC1)(IC2)에 동시에 입력된 B신호는 인버터회로(IC2)에서 한번 반전된 후 출력된다.In detail in the circuit of FIG. 2, the signals of R, G, and B of the image input signal terminal 1 are inverted twice each in the inverter circuit IC 1 to each resistor R 1 (R 2 ) (R 3 ). R and C signals outputted through the inverter circuit (IC 1 ) and inverted once in the inverter circuit (IC 1 ) and B signals input simultaneously to the inverter circuit (IC 1 ) (IC 2 ) are inverted once in the inverter circuit (IC 2 ). Is output.

또한 인텐시티신호(I)는 인버터회로(IC2)에서 반전된 후 R, G, B신호와 와이어-앤드 결합(A)을 이루게 된다. 이렇게 합성된 신호는 저항(R4)(R5)에 의해 파형이 분배되어 믹서 회로인 트랜지스터(Q)의 베이스에 인가된다.In addition, the intensity signal I is inverted in the inverter circuit IC 2 to form a wire-end coupling A with the R, G, and B signals. The synthesized signal is distributed by the resistors R 4 and R 5 and applied to the base of the transistor Q, which is a mixer circuit.

트랜지스터(Q)는 R신호와 G신호가 인버터회로(IC1)(IC2)에서 각각 반전된 신호와 인버터회로(IC2)에서 한번 반전된 B신호와 인텐시티신호(I)가 합성되어 와이어-앤드 결합(A')을 이루게 되며 트랜지스터(Q) 콜렉터측에 접속된 저항(R4)의 크기에 의해 브라운색이 나타나게 된다.In the transistor Q, a signal in which the R signal and the G signal are inverted in the inverter circuit IC 1 (IC 2 ), respectively, and the B signal and the intensity signal I inverted once in the inverter circuit IC 2 are synthesized. An AND bond A 'is formed and brown color is generated by the size of the resistor R 4 connected to the transistor Q collector side.

제2도 (a)도는 저항(R6)을 제거했을 때에 영상신호 출력단(3)의 G신호 출력 파형으로서, 빗금친 부분의 영상신호는 그대로 출력으로 나타나며 노란색만 남게된다.FIG. 2 (a) is a G signal output waveform of the video signal output terminal 3 when the resistor R 6 is removed, and the video signal of the hatched portion is output as it is, leaving only yellow color.

(b)도는 저항(R6)값을 크게하였을 때의 G신호 출력 파형으로서 빗금친 부분의 파형에서 영상신호가 작기 때문에 적색이 실린 노란색이 화면에 나타나게 되며, (c)도는 저항(R6)의 값을 적당한 값으로 하였을 때의 G신호 출력파형으로서, 영상신호와 인텐시티신호(I)가 적절하게 배합되어 브라운색이 화면에 나타나게 된다.(b) is a G signal output waveform when the resistance (R 6 ) is increased. As the video signal is small in the waveform of the shaded portion, yellow with red appears on the screen, and (c) is the resistance (R 6 ). As a G signal output waveform when the value is set to an appropriate value, the video signal and the intensity signal I are appropriately combined so that a brown color appears on the screen.

즉, 각 신호를 합성하는 트랜지스터(Q)의 콜렉터 측에 접속된 저항(R6)의 값을 적당하게 설정하여 출력측의 G신호와 와이어-앤드 결합(A')을 이룸으로서 간단한 회로를 구성하여 브라운색을 재현할 수 있도록 한 것이다.That is, a simple circuit is constructed by appropriately setting the value of the resistor R 6 connected to the collector side of the transistor Q synthesizing each signal to form a wire-and-coupled A 'with the G signal on the output side. The brown color is reproduced.

여기서 콘덴서(C)는 상태 변환을 빨리하게 하며 , 콘덴서(C)가 없게 되면 화상의 노란색 부분과 노란색 옆의 색과의 결계선에 검은선이 남게 되는데 이러한 현상을 보상하는 역활을 하게 된다.In this case, the capacitor C quickly converts the state. If the capacitor C is not present, a black line is left in the boundary line between the yellow part of the image and the color next to the yellow color, which serves to compensate for this phenomenon.

이상에서 서술한 바와 같은 작용으로 이루어지는 본 고안은 종래의 멀티플렉스 회로를 사용하여 브라운색을 나타나게 하는 회로에 비하여 집적회로 및 기타 부품의 수를 줄임으로서 제작상의 간편성과 제품 원가를 저하시킬 수 있으며 설계상의 문제점을 크게 해소할 수 있는 유용한 고안인 것이다.The present invention, which has the functions described above, can reduce the number of integrated circuits and other components by using a conventional multiplex circuit and reduce the number of integrated circuits and other components. It is a useful design that can greatly solve the problem.
