브라운관의 퓨리티 드리프트(Purity Drift) 보상 방법How to compensate for Purity Drift in CRT

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제3도는 A는 본 발명에 의한 브라운관의 퓨리티 드리프트 보상에 따른 프레임 측면에 보상용 밴드를 착설한 상태를 도시한 개략 정단면도, B는 고전류의 인가시 프레임과 일체로 보상용 밴드가 팽창하는 상태를 도시한 개략 정단면도.3 is a schematic front sectional view showing a state in which a compensation band is installed on the side of the frame according to the purity drift compensation of the CRT according to the present invention, and B is a state in which the compensation band expands integrally with the frame upon application of a high current; A schematic front cross-sectional view showing a.

Claims (1)

브라운관의 프레임 측면에 용착에 의해 보상용 밴드를 착설하여 고전류의 인가시 상기 프레임의 열팽창과 동시에 보상용 밴드가 팽창하여 보상 작용을 하도록 하므로써 새도우 마스크의 열팽창을 억제 시키도록 하는 것을 특징으로 하는 브라운관의 퓨리티 드리프트 보상방법.The CRT is installed on the frame side of the CRT to prevent thermal expansion of the shadow mask by suppressing the thermal expansion of the frame and the compensating band when the high current is applied. Purity drift compensation method. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
