Description

음극선관의 필터 그라스Filter glass of cathode ray tube

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

제2도는 본 발명의 필터 그라스의 단면 에서도.2 is a cross-sectional view of the filter glass of the present invention.

제3도는 본 발명의 필터 그라스의 표면을 무광택 처리한 단면 확대도.3 is an enlarged cross-sectional view of a matte finish of the surface of the filter glass of the present invention.

제4도는 본 발명의 필터 그라스가 음극 선관의 곡면과 일치하게 만곡된 상태를보인 예시도.4 is an exemplary view showing a state in which the filter glass of the present invention is curved to match the curved surface of the cathode ray tube.
