음극선관용 새도우 마스크의 제조방법Method of manufacturing shadow mask for cathode ray tube

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

제2도는 이 발명에 따른 새도우 마스크 제조방법을 나타낸 단면도이다.2 is a cross-sectional view showing a shadow mask manufacturing method according to the present invention.

Claims (1)

음극선관의 판넬 내측에 형성된 형광체와 전자총 사이에 설치되어 전자총에서 방상된 전자빔이 통과되도록하는 음극선관용 새도우 마스크의 제조방법에 있어서, 상기 새도우 마스크(20)를 소정의 곡률 상태로 성형하는 폼 공정후에, 수많은 구멍을 형성하기 위한 에칭공정을 실시함으로써 제조됨을 특징으로 하는 음극선관용 새도우 마스크의 제조방법.In the manufacturing method of the shadow mask for cathode ray tube which is installed between the phosphor and the electron gun formed inside the panel of the cathode ray tube to pass the electron beam spun from the electron gun, after the foam process of molding the shadow mask 20 to a predetermined curvature state And manufacturing a shadow mask for a cathode ray tube, by performing an etching process for forming a large number of holes. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
