1 : 수평출력단 2 : 편향코일1: horizontal output stage 2: deflection coil

C1-C4: 콘덴서 R : 저항C 1 -C 4 : Capacitor R: Resistance

Q : 트랜지스터 SW : 동작스위치Q: Transistor SW: Operation Switch

본 고안은 텔레비젼 및 모니터의 수평화면 폭 조정회로에 관한 것으로, 특히 플라이백 펄스의 귀선시간을 증가하여 화면폭을 확대할 수 있는 회로에 관한 것이다.The present invention relates to a horizontal screen width adjustment circuit of a television and a monitor, and more particularly to a circuit that can increase the screen width by increasing the return time of the flyback pulse.

종래의 수평 화면폭 확대 회로는 편향코일의 코일값을 외부의 가변 코일의 인덕턴스 조정으로 톱니파의 진폭을 가변하여 수평 면적을 조정하였으나, 인덕턴스의 값을 조정하기가 쉽지 않았으므로 사용자에게 불편을 주게되어 기기의 신뢰도를 저하 시키게 되었다.Conventional horizontal screen widening circuit adjusts the horizontal area by varying the amplitude of the sawtooth wave by adjusting the inductance of the deflection coil to the inductance of the external coil, but it is not easy to adjust the value of the inductance, which causes inconvenience to the user. The reliability of the device is reduced.

또한 수평 화면을 눌러 사용하기 위하여 수평 출력단에 공급되는 전원(Vcc)을 높이거나 수평 톱니파전류를 크게(즉 진혹을 크게)하면 현재의 화면 폭보가 크게 할 수가 있다.In addition, the current screen width can be increased by increasing the power (Vcc) supplied to the horizontal output terminal or increasing the horizontal sawtooth wave current (that is, increasing the cruelty) in order to press the horizontal screen.

본 고안은 간단한 회로와 스위치의 작동으로 외부에서 펄스의 귀선 시간을 조정하여 전술한 톱니파의 진폭을 변화시켜 화면의 수평면적을 확대하여 사용자의 편의를 도모함으로서 기기의 신뢰도를 높이는데 본 고안의 목적이 있는 것이다.The present invention adjusts the return time of the pulse from the outside by simple circuit and switch operation to change the amplitude of the above-mentioned sawtooth wave and expands the horizontal area of the screen for the convenience of the user to increase the reliability of the device. Is there.

이하 첨부된 도면에 의해, 상세히 설명하면 다음과 같다.With reference to the accompanying drawings, it will be described in detail as follows.

통상의 모니터 수평출력회로(1)에 있어서, 수평 출력단에 콘덴서(C1)(C2)와 콘덴서(C3)(C4)를 각각 직렬연결, 및 평향코일(2)을 접속하고 동작스위치(SW)에 저항 (R)을 통하여 트랜지스터(Q)의 베이스에 연결하여 상기 트랜지스터(Q)의 콜렉터에는 콘덴서(C2)를 연결하는 한편 콘덴서(C1)(C2)를 상호 접속하여서 된 것으로 작용 및 효과를 설명하면 다음과 같다.In the normal monitor horizontal output circuit (1), a condenser (C 1 ) (C 2 ) and a condenser (C 3 ) (C 4 ) are connected in series to the horizontal output terminal, and a parallel coil (2) is connected, and an operation switch is used. (SW) is connected to the base of the transistor (Q) through a resistor (R) to connect the capacitor (C 2 ) to the collector of the transistor (Q) while interconnecting the capacitor (C 1 ) (C 2 ) The function and effect are described as follows.

수평출력단(1)에서 제2a도와 같은 톱니파의 파형이 입력되는 상태에서 동작 스위치(SW)를 온(ON)시키면 저항(R)를 통하여 트랜지스터(Q)의 베이스에 전원(Vcc)이 인기되어 트랜지스터(Q)가 턴온(turn on)상태가 된다.When the operation switch SW is turned on in the state in which the sawtooth wave waveform as shown in FIG. 2a is input from the horizontal output terminal 1, the power supply Vcc is popular at the base of the transistor Q through the resistor R, and the transistor is popular. (Q) is turned on.

이때 콜렉터에 연결된 콘덴서(C2)에는 접지와 연결되어져 콘덴서(C1)(C2)에 의한 합성 용량만큼 귀선 시간이 늘어나게 되어 길어진 귀선시간 만큼 톱니파 전류의 진폭이 증가되고 (제2b도 수평면적이 증가되어 결과적으로 화면의 증가를 기할 수 있는 것이다.At this time, the capacitor C 2 connected to the collector is connected to the ground, and the return time is increased by the combined capacity of the capacitors C 1 and C 2 , so that the amplitude of the sawtooth current is increased by the length of the return time. This increases, resulting in an increase in screen.

상기와 같은 작용으로 이루어지는 본 고안은 종래의 가변 코일로 인덕턴스를 조정함으로 인한 사용자의 불편함을 해소하고 동작 스위치(SW)의 조작으로 수평 화면폭이 증가되어 보다 선명한 화면을 제공할 수 있는 고안인 것이다.The present invention made by the above action is to solve the inconvenience of the user by adjusting the inductance with a conventional variable coil and to increase the horizontal screen width by the operation of the operation switch (SW) to provide a clearer screen will be.
