摘要： A color CRT(Cathode Ray Tube) is provided to attach a thermistor whose resistance value is changed according to a temperature of a deflection part heat sink, correct a current value of an MCM(Magnetic Current Modulator) coil, and correct convergence according to the corrected current value. A horizontal deflection driving unit(10) includes a horizontal deflection correcting unit(11) whose current value is changed according to a temperature of a deflection part heat sink. The horizontal deflection correcting unit includes a thermistor whose value is varied according to a temperature. The thermistor uses an NTC(Negative Terminal Coefficient) whose value is reduced according as the temperature increases.

摘要： 개시된 수평화면크기 조정회로를 갖는 디스플레이장치는 스텝업 방식에 의해 수평화면의 크기를 조정해주도록 함으로써 별도의 소모전력없이 수평화면크기를 증가시켜 줄 수 있는 디스플레이장치에 관한 것이다.
본 고안에 따른 스텝업 방식의 수평화면크기 조정회로를 갖는 디스플레이장치는 인가되는 수평화면크기 조절신호에 따른 펄스폭변조신호를 발생하여 출력하는 펼스폭변조신호 발생부의 출력신호에 의해 구동되며, 스텝업 방식에 따른 수평화면 크기 조정신호를 포함하는 전류를 수평화면크기 조정용 코일을 통해 수평출력 회로부로 공급하는 수평화면크기 조정부와, 수평발진 주파수에 의해 구동되는 수평구동회로부의 출력신호에 의해 구동되어 수평화면 크기 조정부로부터 입력되는 전류를 수평편향코일에 공급해주는 수평출력 회로부와, 수평출력 회로부에 의해 전류를 공급 받아 전자빔을 수평편향 시켜주는 수평편향코일과, 수평편향코일과 직렬접속되어 화면에 표시되는 화상의 직선성을 보정해 주는 S자보정 콘덴서를 구비함을 특징으로 한 다.
따라서, 본 고안의 장치는 높은 수평편향 주파수에서 수평화면의 크기를 증가시켜주더라도 이중트리거 현상이 발생하지 않을 뿐만 아니라 별도의 소모전력도 필요하지 않다는 장점을 갖는다.
