본 고안은 멀티동기(Multi Syne) 칼라모니터의 수평 사이즈 조정회로에 관한 것이다.The present invention relates to a horizontal size adjustment circuit of a multi synchronous color monitor.
일반적으로 칼라모니터는 용도 및 제작상의 사양에 따라 모니터의 수평주파수를 15KHZ-35KHZ의 범위내에서 여러형태로 해당특정 주파수만으로 고정되어 사용하여 왔었다.In general, color monitors have been used in a variety of forms within the range of 15KHZ-35KHZ, depending on the application and specifications of the monitor.
예를들어 모니터상의 수평주파수가 15KHZ시 수평 편향요크에 전류를 많이 흘려 수평사이즈를 크게하고, 22-35KHZ의 수평주파수시일시 상기 수평 편향요크에 전류를 적게흘려 수평사이즈를 작게 한다.For example, when the horizontal frequency on the monitor is 15KHZ, a large amount of current flows to the horizontal deflection yoke, and when the horizontal frequency is 22-35KHZ, a small amount of current flows to the horizontal deflection yoke to reduce the horizontal size.
종래 일반적인 모니터의 수평사이즈는 입력되는 수평주파수에 따라 결정되어지므로 사용자의 취향에 따라 용이하게 선택할 수 없도록 되어 있었다. 즉 모니터의 사용되는 주파수에 따라 각각 한가지의 수평 사이즈에만 고정되어 있었다. 이를 개선하는 방법으로 종래 제1도를 이용하였다.Since the horizontal size of the conventional general monitor is determined according to the input horizontal frequency, it cannot be easily selected according to the user's taste. In other words, depending on the frequency of the monitor, only one horizontal size was fixed. As a method of improving this, the conventional FIG. 1 is used.
제1도를 참조하여 종래기술을 구체적으로 설명하면, 제1입력단(I1)으로 수평발진부 출력 24KHZ신호가 저항(R5)과 코일(L4)로 구성된 병렬회로를 통해 정형화하여 트랜지스터(Q3)의 베이스에 인가되어 증폭된 후 플라이백 트랜스포머(FBT)를 지나 씨알티의 애노드로 인가된다.Referring to FIG. 1, the prior art will be described in detail. The horizontal oscillator output 24KHZ signal to the first input terminal I1 is shaped through a parallel circuit composed of a resistor R5 and a coil L4 to form the base of the transistor Q3. It is then amplified and passed through a flyback transformer (FBT) to the anode of Citi.
그리고 제2입력단(12)으로 15-25KHZ의 수평주파수가 입력되어지는데, 15KHZ 일때는 주파수/전압변압기에서 "하이"가 되어 트랜지스터(Q1, Q2)를 온한다. 이때 제1, 2릴레이(Ry1, Ry2)가 구동되어 릴레이 스위치(SW1-SW3)가 온된다. 이때 캐패시터(C4, C5)가 병렬로 구성되어 용량이 증가되고, 캐패시터(C6, C7)및 (C8)의 연결이 병렬로 된다. 따라서 상기 캐패시터(C 4, C5)에 충전된 전류가 제1, 3코일(L10, L30)을 통해 흐름과 동시에 트랜스포머(L40)를 통해 흐른다. 그리고 제1릴레이(Ry1)에서의 전류는 스위치(SW1)를 통해 흐르므로 수평편향요크코일(H-DY)에 많은 전류를 흘릴 수 있다. 상기 제1코일(L10)과 연결된 캐패시터(C1) 및 저항(R1)의 구성은 씨알티 화면의 수평폭을 결정하고, 제2코일(L20)은 세로간격이 조절되며, 제3코일(L30)과 캐패시터(C2), 저항(R5)에 의해 칼럼(Colum) 라인폭을 조절하며, 제4코일(L40)에 의해 로우(Row)폭이 조정된다.A horizontal frequency of 15-25KHZ is input to the second input terminal 12. When the 15KHZ is turned on, the transistors Q1 and Q2 are turned on by being "high" in the frequency / voltage transformer. At this time, the first and second relays Ry1 and Ry2 are driven to turn on the relay switches SW1 to SW3. At this time, the capacitors C4 and C5 are configured in parallel to increase the capacity, and the connection of the capacitors C6 and C7 and C8 is in parallel. Therefore, the current charged in the capacitors C 4 and C5 flows through the transformer L40 while simultaneously flowing through the first and third coils L10 and L30. Since the current in the first relay Ry1 flows through the switch SW1, a large amount of current can flow through the horizontal deflection yoke coil H-DY. The configuration of the capacitor C1 and the resistor R1 connected to the first coil L10 determines the horizontal width of the CALTI screen, and the vertical length of the second coil L20 is adjusted, and the third coil L30. The column line width is adjusted by the capacitor C2 and the resistor R5, and the row width is adjusted by the fourth coil L40.
즉, 상기 트랜지스터(Q1,Q2)의 온에 따라 수평편향요크코일(H-DY)에 전류를 많이 흘려 화면의 수평 사이즈가 커지게되는 해당 폭을 조정한다. 제2입력단(12)으로 22-35KHZ의 수평주파수가 입력되면 주파수/전압변환기에서 "로우"가 발생되어 트랜지스터(Q1, Q2)는 오프된다. 이때 캐패시터(C5)와 (C4)에 의해 용량성은 분리되고, 제1,2릴레이(Ry1, Ry2)가 오프되어지므로 스위치(SW1-SW3)가 오프되어 제2코일(L20) 및 각 코일(L10, L30-L40)에 의해 수평 편향요크 코일(H-DY)에는 전류가 적게 흐른다. 이에 따라 화면이 수평 사이즈의 폭이 적어지게 되어 화면 수평폭이 조정된다.That is, according to the on of the transistors Q1 and Q2, a large amount of current flows through the horizontal deflection yoke coil H-DY to adjust a corresponding width to increase the horizontal size of the screen. When the horizontal frequency of 22-35KHZ is input to the second input terminal 12, " low " is generated in the frequency / voltage converter to turn off the transistors Q1 and Q2. At this time, the capacitive is separated by the capacitors C5 and C4, and since the first and second relays Ry1 and Ry2 are turned off, the switches SW1-SW3 are turned off, so that the second coil L20 and each coil L10 are turned off. By the L30-L40, a small current flows to the horizontal deflection yoke coil H-DY. As a result, the width of the screen becomes smaller so that the screen horizontal width is adjusted.
상술한 바와같이 제1, 2릴레이(Ry1, Ry2)로 구성된 릴레이 2개, 화면의 수평폭조절코일(L20, L20)로 구성된 코일2개로 구성되어 수평 사이즈를 맞추도록 되어 있으므로 회로구성이 복잡해지는 문제점이 있었다.As described above, two relays constituted by the first and second relays Ry1 and Ry2 and two coils constituted by the horizontal width control coils L20 and L20 of the screen are adapted to match the horizontal size, thereby complicating the circuit configuration. There was a problem.
따라서 본 고안의 목적은 간단한 최소한의 회로구성으로 15-35KHZ의 어느 수평주파수가 인가되어도 해당 수평 사이즈를 원하는 폭에 맞게 자유롭게 조절할 수 있는 회로를 제공함에 있다.Accordingly, an object of the present invention is to provide a circuit that can freely adjust the horizontal size to a desired width even if any horizontal frequency of 15-35KHZ is applied with a simple minimum circuit configuration.
이하 본 고안을 첨부된 도면을 참조하여 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제2도는 본 고안에 따른 회로도로서, 주파수/전압변환기(100)의 출력단인 제1입력단(I1)에 저항(R4)을 접속한 후 트랜지스터(Q1)의 베이스에 연결하고, 상기 트랜지스터(Q1)의 콜렉터에 릴레이(Ry10)를 연결한다. 상기 릴레이(Ry10)의 스위치(SW2, SW1)와 씨알티 에노드 고압신호 발생부(10)의 구성은 제1도와 동일하여 동일 부호를 부여 하였으며, 상기 릴레이(Ry10)의 전원과 동일하게 인가되도록 전원단(B+)에 씨알티화면의 로우(ROW)폭을 조절하는 트랜스포머형 사이드(side) 핀큐션코일(L40)을 연결한다.FIG. 2 is a circuit diagram according to the present invention. The resistor R4 is connected to the first input terminal I1, which is an output terminal of the frequency / voltage converter 100, and then connected to the base of the transistor Q1. Connect the relay (Ry10) to the collector of. Configurations of the switches SW2 and SW1 of the relay Ry10 and the CT high voltage signal generator 10 are the same as those of FIG. 1, and are assigned the same reference signs, so that they are applied in the same manner as the power of the relay Ry10. The transformer type side pincushion coil (L40) for adjusting the row width of the CT screen is connected to the power supply terminal (B +).
상기 사이드 핀큐션코일(L40)과 직렬로 세로간격을 조절하는 수평 린리어리티코일(L20)과 화면수평폭을 조절하는 제1코일(L10) 및 수평편향 요크코일(H-DY)이 제1도와 같이 구성된다.The horizontal linierity coil L20 for adjusting the vertical spacing in series with the side pincushion coil L40 and the first coil L10 for adjusting the screen horizontal width and the horizontal deflection yoke coil H-DY are first It is composed of tiles.
따라서 본 고안의 구체적 일실시예를 제2도를 참조하여 상세히 설명하면, 트랜지스터(Q3)는 수평출력 트랜지스터로서 고압을 발생시키는데, 제2입력단(12)으로 25KHZ 펄스가 입력되며, 저항(R5) 및 코일(L4)에 의해 상기 입력파형을 정형화하여 증폭한 후 플라이백 트랜스(FBT)에 의해 씨알티엔노드로 인가될 고압을 발생 한다.Therefore, when a specific embodiment of the present invention is described in detail with reference to FIG. 2, the transistor Q3 generates a high voltage as a horizontal output transistor. A 25KHZ pulse is input to the second input terminal 12 and a resistor R5. And amplifying and amplifying the input waveform by the coil L4 to generate a high pressure to be applied to the SALTI node by a flyback transformer (FBT).
그리고 제1입력단(11)으로는 주파수/전압변환기(100)에서 15KHZ시 "하이"가 발생되어 저항(R4)을 통해 트랜지스터(Q1)를 온한다.In the first input terminal 11, "high" is generated at the 15 KHZ at the frequency / voltage converter 100 to turn on the transistor Q1 through the resistor R4.
이에따라 릴레이(Ry10)를 구동하여 스위치(SW2, SW1)를 온한다.Accordingly, the relay Ry10 is driven to turn on the switches SW2 and SW1.
상기 스위치(SW1)에 의해 캐패시터(C3, C4) 에 의한 병렬 연결로 용량이 증가되고, 스위치(SW2)에 의해 캐패시터(C5, C6) 및 캐패시터(C7)를 병렬로 연결하여 용량증가로 편향전류를 고르게 흐르도록 한다.The capacity is increased by the parallel connection by the capacitors C3 and C4 by the switch SW1, and the deflection current is increased by the capacity increase by connecting the capacitors C5 and C6 and the capacitor C7 in parallel by the switch SW2. Make the flow evenly.
상기 캐패시터(C3, C4)에 의한 용량증가로 사이드 핀큐션코일(L40)에 전류를 흘려 씨알티 화면의 사이즈 로우폭을 조절한다.As the capacitors C3 and C4 increase the capacity, a current flows through the side pincushion coil L40 to adjust the size low width of the CALTI screen.
상기 핀큐션코일(L40)을 통한 전류가 수평 린리어리티코일(L20)에 흘려 화면의 칼럼 라인폭을 조절한다.The current through the pincushion coil L40 flows through the horizontal linririity coil L20 to adjust the column line width of the screen.
상기 수평 린리어리티 코일(L20)를 통한 전류가 흘려지므로 캐패시터(C3, C4)와 제1코일(L10)에 의해 원하는 사이즈로 수평폭은 크기를 조절하며, 수평편향요크코일(H-DY)를 통해 전류를 흐른다. 따라서 코일로 흐르는 전류가 크면 수평사이즈가 크고, 전류가 적어지면 수평사이즈가 적어진다.Since the current flows through the horizontal linriity coil L20, the horizontal width is adjusted to a desired size by the capacitors C3 and C4 and the first coil L10, and the horizontal deflection yoke coil H-DY. Current flows through it. Therefore, the larger the current flowing through the coil, the larger the horizontal size, and the smaller the current, the smaller the horizontal size.
한편 22-35KHZ시 주파수/전압변환기(100)의 출력이 "로우"가 되어 트랜지스터(Q1)이 오프되고, 스위치(SW1, W2)도 오프되므로 캐패시터(C3, C4) 및 캐패시터(C5-C7)의 용량은 적어진다. 이때 코일(L40, L20, L10)을 통해 전류를 적게 흐르므로 해당 씨알티의 수평 사이즈를 적게 조절하는데, 즉 캐패시터(C4)와 제1코일(L10)에 의해 원하는 사이즈로 적게 조절된다.On the other hand, the transistor Q1 is turned off and the switches SW1 and W2 are turned off because the output of the frequency / voltage converter 100 is "low" at 22-35KHZ, so that the capacitors C3 and C4 and the capacitor C5-C7 are turned off. The capacity of is reduced. At this time, since the current flows less through the coils L40, L20, and L10, the horizontal size of the corresponding CALTI is adjusted less, that is, the capacitor C4 and the first coil L10 are less adjusted to the desired size.
상술한 바와같이 수평폭 조절 코일 1개와 릴레이 하나로 간단히 수평사이즈를 모든 주파수 모드에 맞게 조절할 수 있으므로 회로구성을 단순화하는 반면 원가절감할 수 있는 이점이 있다.As described above, since one horizontal width adjusting coil and one relay can easily adjust the horizontal size to all frequency modes, the circuit configuration can be simplified while reducing the cost.
