본 고안은 텔레비젼 수상기를 마이크로 컴퓨터의 모니터로 사용할 때 문자 발생장치의 출력을 1×4디멀티플렉서를 통해 텔레비젼 수상기 휘도 신호와 청, 적, 녹색 신호단에 각각 연결하여 4개 색상중 한 개의 색상을 임의로 선택하여 선택한 색상으로 문자가 화면에 표시될 수 있도록 한 모니터로 표시되는 문자의 색상 선택회로 구성에 관한 것이다.The present invention, when using a TV receiver as a monitor for a microcomputer, connects the output of the character generator to the television receiver's luminance signal and the blue, red, and green signal stages through a 1 × 4 multiplexer, and randomly selects one of four colors. The present invention relates to a color selection circuit configuration of characters displayed by one monitor so that characters can be displayed on the screen in a selected color.

종래에는 텔레비젼 수상기를 컴퓨터 모니터로 사용할 때 화면에 표시되는 문자의 색상이 한가지로 고정되어 있으므로 사용자의 기호에 맞출 수 없었고 또 같은 색으로 계속 사용하다 보면 눈에 피로를 느끼게 될 뿐만 아니라 싫증나게 되었던 문제점이 있었다.Conventionally, when the TV receiver is used as a computer monitor, the color of the characters displayed on the screen is fixed to one, so that it cannot be matched to the user's preferences. There was this.

본 고안은 이와 같은 문제점을 해결하기 위하여 모니터의 화면에 표시되는 문자의 색상을 사용자가 4가지중 한가지로 임의로 선택할 수 있도록 하므로서 좋아하는 색상으로 문자를 표시하도록 하고 눈의 피로를 줄일 수 있게 한 것이다.In order to solve the above problems, the present invention allows the user to select one of four colors of characters displayed on the screen of the monitor so that the characters can be displayed in a favorite color and the eyes can be reduced. .

본 고안 장치의 구성은 제1도에서와 같이, 디멀티플렉서(1)의 입력단자(I0)는 문자 발생장치(2)의 출력단자(Q0)에 연결하고, 출력단자(Y0,Y1,Y2,Y3)는 각각 증폭기(3,4,5,6)를 통해 텔레비젼 수상기의 휘도 신호(Y)단과 색차 신호(G-Y, R-Y, B-Y)단에 각각 연결하며, 디멀티플렉서(1)의 제어 단자(S0,S1)는 스위치(SW)를 온할때마다 클록이 입력되는 2진 계수기(7)의 출력(Q0,Q1)에 각각 연결하여서 된 것으로서, NBLK는 문자 발생기의 블랭킹 신호 출력단자, C1,C2는 콘덴서, R1은 저항, Vcc는 전원이다.The configuration of the device of the present invention, as shown in Figure 1, the input terminal (I 0 ) of the demultiplexer 1 is connected to the output terminal (Q 0 ) of the character generator 2, the output terminals (Y 0 , Y 1) , Y 2 , Y 3 are connected to the luminance signal (Y) stage and the chrominance signal (GY, RY, BY) stage of the television receiver, respectively, via amplifiers (3, 4, 5, 6), respectively. The control terminals S 0 and S 1 are connected to the outputs Q 0 and Q 1 of the binary counter 7, which is clocked each time the switch SW is turned on. NBLK is a blanking of the character generator. Signal output terminals, C 1 and C 2 are capacitors, R 1 is a resistor and Vcc is a power supply.

본 고안의 작용 효과는 제1도에서와 같이 최초의 전원 투입시 2진 계수기(7)의 출력(Q0,Q1)은 ″00″이므로 이 신호가 제어단자(S0,S1)로 입력되는 디멀티플렉서(1)는 입력단자(I0)와 출력단자(Y0)가 연결되어 문자 발생장치(2)의 출력단자(Q0)에서 출력되는 문자 신호는 디멀티플렉서(1)의 출력단자(Y0)와 증폭기(3)을 통해 텔레비젼 수상기의 휘도 신호단에 공급된다.The effect of the present invention is that the output Q 0 , Q 1 of the binary counter 7 is ″ 00 ″ as shown in FIG. 1 so that this signal is transferred to the control terminals S 0 , S 1 . The input demultiplexer 1 is connected to an input terminal I 0 and an output terminal Y 0 so that the text signal output from the output terminal Q 0 of the character generator 2 is an output terminal of the demultiplexer 1. Y 0 ) and amplifier 3 are supplied to the luminance signal stage of the television receiver.

따라서, 이때에 화면에 표시되는 문자의 색상은 백색이 되는 것이다.Therefore, at this time, the color of the characters displayed on the screen becomes white.

스위치(SW)를 한번 누르면 2진 계수기(7)의 클루단자(CK)에 클록펄스가 입력되어 출력(Q0,Q1)은 ″10″이 된다.When the switch SW is pressed once, the clock pulse is input to the clock terminal CK of the binary counter 7 and the outputs Q 0 and Q 1 become ″ 10 ″.

따라서 디멀티플렉서(1)의 입력단자(I0)는 출력단자(Y2)와 연결되어 문자 발생장치(2)의 출력단자(Q0)에서 출력되는 문자신호는 디멀티플렉서(1)이 출력단자(Y2)와 증폭기(4)를 통해 텔레비젼 수상기의 색차 신호(R-Y)단에 공급되므로 이때의 문자의 색상은 적색이 되는 것이다.Therefore, the input terminal I 0 of the demultiplexer 1 is connected to the output terminal Y 2 so that the character signal output from the output terminal Q 0 of the character generator 2 is the output terminal Y of the demultiplexer 1. 2 ) and the amplifier 4 are supplied to the color difference signal RY stage of the television receiver, and the color of the characters at this time becomes red.

같은 방법으로 스위치(SW)를 누를 때마다, 2진 계수기(7)의 출력(Q0,Q1)은 ″01″″11″로 변화되고 디멀티플렉서(1)의 입력단자(I0)는 출력단자(Y1,Y3)와 차례로 연결되어 문자 발생장치(2)의 출력이 텔레비젼 수상기의 색차신호(G-Y,B-Y)단에 공급된다.Each time the switch SW is pressed in the same way, the output (Q 0 , Q 1 ) of the binary counter 7 changes to ″ 01 ″ ″ 11 ″ and the input terminal I 0 of the demultiplexer 1 is output. The outputs of the character generator 2 are supplied to the color difference signals GY, BY of the television receiver, in turn, connected to the terminals Y 1 , Y 3 .

따라서 이때의 문자의 색상은 녹색과 청색으로 선택되는 것이다.Therefore, the color of the text is selected from green and blue.

이와 같이 본 고안에 의하면 모니터 화면에 표시되는 문자의 색상을 여러 가지로 선택하여 사용할 수 있으므로 모니터 사용이 편리해 지게 된 것이다.As such, according to the present invention, it is possible to select and use various colors of the characters displayed on the monitor screen, which makes the monitor easier to use.
