공용단자를 이용한 16칼러 및 64칼러 재생장치16 color and 64 color playback device using common terminal

제1도는 본 고안 장치의 회로도.1 is a circuit diagram of the device of the present invention.

본 고안은 컴퓨터에서 출력되는 16칼러 디지털 신호 및 64칼러 디지털 신호를 동일 입력단자로 공급받아 모드 전환에 따라서 16칼러, 64칼러를 표시화면에 재생할 수 있는 회로에 관한 것이다.The present invention relates to a circuit capable of reproducing 16 colors and 64 colors on a display screen by receiving 16 color digital signals and 64 color digital signals output from a computer through the same input terminal.

종래에는 컴퓨터에서 출력되는 신호가 디지털 영상신호일때 16칼러 디지털 신호는 전용으로 16칼러로를 재생할 수 있는 연결 단자에 의해 16칼러를 표시화면에 재생하였으며, 64칼러 신호를 컴퓨터에 공급한다면 64칼러를 재생할 수 있는 표시, 모니터를 필요로 하므로 2개의 별개 모니터를 필요로 한다는 불합리성이 있었다.Conventionally, when the signal output from the computer is a digital video signal, 16 colors are reproduced on the display screen by a connection terminal capable of exclusively reproducing 16 colors and 16 colors on the display screen. There was an irrationality that two separate monitors were required because they needed a display and a monitor that could be reproduced.

본 고안은 이러한 종래의 문제점을 없이하도록, 컴퓨터에서 각각의 두 모드에 의해 16칼러 디지털 신호와 64칼러 디지털 신호를 공급할 경우에 동일 단자로 입력시켜 각각의 모드에 해당하는 16칼러와 64칼러를 재생할 수 있는 16칼러 및 64칼러 재생장치를 제공하는 것을 목적으로 하며 이하 첨부된 도면을 참조하면서 본 고안의 구성 및 작용 효과를 설명하면 다음과 같다.The present invention reproduces 16 colors and 64 colors corresponding to each mode by inputting to the same terminal when supplying 16 color digital signal and 64 color digital signal in each of two modes in the computer so as to avoid such a conventional problem. It is an object of the present invention to provide a 16-color and 64-color reproducing apparatus that can be described below with reference to the accompanying drawings.

제1도를 참조하면, 본 고안의 구성은, 각각의 색신호 입력단자(R, G, B, r, g, b)를 트랜지스터(Q1~Q12)로 구성된 각 증폭기(가-바)에 연결하고, 증폭기(가-다)의 각 출력은 적, 녹, 청색 출력단자(ㄱ-ㄷ)에 연결하되 증폭기(라-바)의 출력은 다이오드(D2~D4)를 통하여 공통접속하여 트랜지스터(Q16)의 베이스와 모드 절환공급기(1)에 연결하며, 증폭기(마)의 출력은 다이오드(D1)와 저항(R25)을 통하여 트랜지스터(Q16)의 베이스에 연결하되 증폭기(라-바)의 출력은 저항(R20, R23, R24)을 통하여 트랜지스터(Q13~Q15)에 연결하되 트랜지스터(Q13~Q15)의 에미터 출력은 다이오드(D6~D8)와 저항(R30~R32)을 각각 통하여, 적, 녹, 청 출력단자(ㄱ-ㄷ)에 각각 연결함과 동시에 다이오드(D9~D11)를 통하여 트랜지스터(Q16)의 에미터 출력에 연결하여된 구성으로서 이러한 본 고안의 작용 효과는 16칼러 디지털 신호는 입력단자(R, G, B)로 적, 녹, 청의 원색신호가 입력되고 휘도신호는 단자(g)로 입력된다.Referring to FIG. 1, the constitution of the present invention provides each of the color signal input terminals R, G, B, r, g, and b to each amplifier (ga-bar) composed of transistors Q 1 to Q 12 . Each output of the amplifier (ga-da) is connected to the red, green, and blue output terminals (a-c), but the outputs of the amplifier (la-bar) are commonly connected through diodes (D 2 to D 4 ). The output of the amplifier (E) is connected to the base of the transistor (Q 16 ) through the diode (D 1 ) and the resistor (R 25 ), and to the base of the transistor (Q 16 ) and the mode switching supply (1). The output of R-bar is connected to transistors Q 13 to Q 15 through resistors R 20 , R 23 and R 24 , but the emitter outputs of transistors Q 13 to Q 15 are diodes D 6 to D 8 ) and through the resistors R 30 to R 32 , respectively, to the red, green, and blue output terminals (a-c), and at the same time through the diodes D 9 to D 11 , the emitter of the transistor Q 16 . Is connected to the output of the Such operation and effect of the present design is 16-color digital signal input terminals (R, G, B) to the red, green and blue primary color signals and the input luminance signal is input to the terminal (g).

또한 64칼러 디지털 신호는 입력단자(R, G, B)로 적, 녹, 청 원색신호가 입력되고, 적, 녹, 청의 휘도신호는 입력단자(r, g, b)로 각각 입력된다.In addition, the 64 color digital signal is inputted with the red, green, and blue primary colors signals through the input terminals R, G, and B, and the luminance signals of the red, green, and blue colors are input through the input terminals r, g, and b, respectively.

먼저 16칼러 디지털 신호가 입력될 때 모드 절환 전압 공급기(1)의 출력이 로우 전압이 되어 다이오드(D2, D3, D4)가 온되어 트랜지스터(Q13, Q14, Q15)의 베이스에는 로우 전압이 걸리게 됨으로 트랜지스터(Q13, Q14, Q15)는 오프된다. 에미터에는 ″0″ V의 로우 전압이 걸리므로 다이오드(D6, D7, D8)는 오프된다.First, when the 16-color digital signal is input, the output of the mode switching voltage supply 1 becomes a low voltage so that the diodes D 2 , D 3 , and D 4 are turned on so that the bases of the transistors Q 13 , Q 14 , and Q 15 are turned on. Transistors Q 13 , Q 14 , and Q 15 are turned off because a low voltage is applied to the circuit. The emitter has a low voltage of ″ 0 ″ V, so diodes D6, D 7 and D 8 are turned off.

단자(g)로 입력된 휘도신호는 트랜지스터(Q5, Q11)를 거치면서 증폭되어 다이오드(D1), 저항(R25)을 거쳐 트랜지스터(Q16)의 베이스에 걸리게 된다. 이때 트랜지스터(Q16)는 온되어 휘도신호는 트랜지스터(Q16)의 에미터에서 다이오드(D9, D10, D11)를 통하여 단자(R, G, B)로 입력된 원색 적, 녹, 청 신호와 합쳐져서 재생하게 된다.The luminance signal input to the terminal g is amplified while passing through the transistors Q 5 and Q 11 to be caught by the base of the transistor Q 16 via the diode D 1 and the resistor R 25 . At this time, the transistor Q 16 is turned on, and the luminance signal is inputted to the terminals R, G, and B through the diodes D 9 , D 10 , and D 11 from the emitter of the transistor Q 16 . Combined with the green signal to play.

64칼러의 디지털 신호가 입력될 때 모드 절환 전압 공급기인(1)의 출력이 하이 전압이 되어 다이오드(D2, D3, D4)는 오프 상태가 된다.When the 64 color digital signal is input, the output of the mode switching voltage supply 1 becomes a high voltage, and the diodes D 2 , D 3 , and D 4 are turned off.

이때 입력단자(R, G, B)에서는 원색의 적, 녹, 청 신호가 각각 트랜지스터(Q1, Q2, Q3, Q7, Q8, Q9)를 거쳐 버퍼 증폭되어 저항(R18, R20, R21)을 통하게 된다. 단자(r, g, b)에 입력된 적, 녹, 청의 휘도신호중 r신호는 트랜지스터(Q4, Q10)을 통하여 버퍼 증폭되어 저항(R2)을 통하여 다이오드(D2)가 오프되어 있기 때문에 통하지 못하고 트랜지스터(Q13)를 온하여 다이오드(D6)를 통해 다이오드(D9)가 오프되어 있기 때문에 저항(R19)에서 나온 원색의 적신호와 합쳐지게 된다.At this time, the input terminal (R, G, B) in the through the red, green, and blue signals, each transistor (Q 1, Q 2, Q 3, Q 7, Q 8, Q 9) of the primary amplification buffer resistor (R 18 , R 20 , R 21 ). The r signal among the red, green, and blue luminance signals input to the terminals r, g, and b is buffer-amplified through the transistors Q 4 and Q 10 and the diode D 2 is turned off through the resistor R 2 . Therefore, since the transistor Q 13 is turned on and the diode D 9 is turned off through the diode D 6 , the red signal of the primary color from the resistor R 19 is combined.

녹색의 휘도신호인 g신호는 트랜지스터(Q5, Q11)를 거쳐 버퍼 증폭되어 저항(R23)을 거쳐 다이오드(D3)가 오프되어 있기 때문에 통하지 못하고 트랜지스터(Q14)의 베이스에 하이전압이 걸리므로 트랜지스터(Q14)가 온되어 다이오드(D7)를 통하게 된다.The signal g, which is a green luminance signal, is buffered and amplified through the transistors Q 5 and Q 11 and is not passed because the diode D 3 is turned off through the resistor R 23 , but the high voltage is applied to the base of the transistor Q 14 . This causes transistor Q 14 to turn on and pass through diode D 7 .

청색의 휘도신호인 b신호는 트랜지스터(Q6, Q12)를 거쳐 버퍼 증폭되어 저항(R24)을 거쳐 다이오드(D4)가 오프되어 있기 때문에 트랜지스터(Q15)의 베이스에 하이 전압이 걸리게 된다.The b signal, which is a blue luminance signal, is buffered and amplified through the transistors Q 6 and Q 12 and the diode D 4 is turned off through the resistor R 24 so that a high voltage is applied to the base of the transistor Q 15 . do.

트랜지스터(Q14)가 온되어 다이오드(D8)를 거쳐 다이오드(D11)가 오프되어 있기 때문에 저항(R32)을 거쳐 단자(B)에 들어온 원색의 청색 신호와 합쳐지게 된다.Since the transistor Q 14 is turned on and the diode D 11 is turned off via the diode D 8 , the transistor Q 14 is combined with the primary blue signal entering the terminal B through the resistor R 32 .

이상에서 설명된 바와 같이 본 고안은 상술한 회로를 이용하여 컴퓨터에서 16칼러 디지털 신호나 64칼러 디지털 신호가 출력될 경우 동일 입력단자를 이용하여 16칼러 신호와 64칼러 신호를 재생하므로서 호환성 있는 표시 모니터를 제공할 수 있다.As described above, according to the present invention, when a 16 color digital signal or a 64 color digital signal is output from a computer using the above-described circuit, the display monitor is compatible by reproducing 16 color signals and 64 color signals using the same input terminal. Can be provided.
