Abstract

음극선관에서 색선별기능을 갖는 섀도우마스크가 개선된 음극선관에 관한 것으로, 제1섀도우마스크가 전자빔에 의하여 열팽창되는 것을 개선하기 위하여 전자총과 제1섀도우마스크 사이의 패널 또는 펀넬의 내면 설치되는 또 하나의 제2섀도우마스크를 설치하여 이 제2섀도우마스크가 제1마스크에 조사되는 전자빔을 차단하도록 하였다.The present invention relates to a cathode ray tube in which a shadow mask having a color screening function is improved in a cathode ray tube, wherein an inner surface of a panel or a funnel between the electron gun and the first shadow mask is installed to improve thermal expansion of the first shadow mask by an electron beam. A second shadow mask was installed to block the electron beam irradiated onto the first mask.

Description

음극선관Cathode ray tube

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

제3도는 본 발명에 따른 음극선관의 주요부를 확대하여 도시한 단면도이다.3 is an enlarged cross-sectional view showing the main part of the cathode ray tube according to the present invention.

Claims (2)

음극선관의 네크부 설치되어 전자빔을 방출하는 적어도 하나의 전자총과, 상기 음극선관의 패널부 내면에 도포되어 상기 전자빔에 의하여 발광하는 스크린과, 상기 음극선관의 펀넬부 외부에 설치되어 상기 전자빔이 상기 스크린의 소정부위를 향하도록 편향시키는 편향기와, 상기 전자총과 상기 스크린 사이에 설치되어 상기 편향된 전자빔을 선택적으로 통과시키기 위하여 제1슬릿구멍이 다수개 형성되며 상기 패널의 내면에 고정되는 제1섀도우마스크를 구비한 음극선관에 있어서, 상기 전자총과 상기 제1섀도우마스크 사이의 패널 또는 펀넬의 내면에 설치되어 상기 제1슬릿구멍을 통과할 전자빔을 통과시키는 제2슬릿구멍이 형성된 제2섀도우마스크를 구비하여 제1섀도우마스크에 조사되는 전자빔을 줄이는 것을 특징으로 하는 음극선관.At least one electron gun provided at the neck portion of the cathode ray tube to emit an electron beam, a screen applied to an inner surface of the panel portion of the cathode ray tube to emit light by the electron beam, and installed outside the funnel portion of the cathode ray tube to provide the electron beam A first shadow mask provided between the deflector for deflecting a predetermined portion of the screen and a plurality of first slit holes formed between the electron gun and the screen to selectively pass the deflected electron beam and fixed to an inner surface of the panel; A cathode ray tube comprising: a second shadow mask provided on an inner surface of a panel or funnel between the electron gun and the first shadow mask, the second shadow mask having a second slit hole for passing an electron beam to pass through the first slit hole Cathode ray tube, characterized in that for reducing the electron beam irradiated to the first shadow mask. 제1항에 있어서, 상기 제1섀도우마스크 및 제2섀도우마스크를 지지하는 프레임과, 상기 패널 또는 펀넬의 내면에 형성된 스터드핀과, 상기 프레임에 일단이 상기 스트드핀에 다탄이 설치된 훅스프링을 더 구비하는 것을 특징으로 하는 음극선관.The frame of claim 1, further comprising a frame supporting the first shadow mask and the second shadow mask, a stud pin formed on an inner surface of the panel or the funnel, and a hook spring having one end of the frame attached to the stud pin. Cathode ray tube characterized in that it comprises. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
