Abstract

본 발명은 멀티-스캔 디스플레이 시스템의 입력모드에 따른 B+ 자동조정장치에 관한 것으로 종래에는 조정부 하나로 고압변동에 따라서 수평편향회로부와 고압회로부에 B+를 공급함으로 해서 화명에 노이즈가 발생할 우려가 있고, 조정이 어려운 점을 개선하기 위한 것이다.The present invention relates to a B + automatic adjustment device according to the input mode of a multi-scan display system. Conventionally, there is a possibility that noise may occur in a picture by supplying B + to a horizontal deflection circuit part and a high voltage circuit part according to a high pressure change with one adjustment part. This is to improve the difficulty of adjustment.

이와같은 본 발명은 편향코일에 편향전류를 발생시키는 수평 편향 회로부와, CRT에 고압을 인가하기 위해 일차적으로 고압펄스를 발생시키는 고압회로부에 각각 독립적으로 B+를 인가할 수 있도록 제1조정부와, 제2조정부를 설치하여 입력모드변화에 의한 고압변도에 대하여 자동으로 B+를 조정하여 최적값으로 셋팅시킬 수 있게 하였다.As described above, the present invention provides a horizontal deflection circuit unit for generating a deflection current in the deflection coil, a first adjusting unit for independently applying B + to the high voltage circuit unit for generating a high voltage pulse primarily for applying a high pressure to the CRT, The second adjustment unit was installed to automatically adjust B + to the optimum value for high pressure variations caused by input mode changes.

따라서, 멀티 스캔 디스플레이 장치의 디스플레이를 안정화시켰다.Thus, the display of the multi-scan display device is stabilized.
