Abstract

본 발명은 스트라이프형 칼라브라운관을 노광하는 신규한 방법을 개시한다. R, G, B 전자총의 위치를 보상하기 위해 시프팅렌즈를 회전시키는 방법을 사용하였는데, 중앙 형광체의 노광시 시프팅렌즈가 조광패턴을 왜곡시키는 문제가 있었다.The present invention discloses a novel method of exposing a stripe type color cathode ray tube. A method of rotating the shifting lens to compensate for the position of the R, G, and B electron guns has been used. However, there has been a problem that the shifting lens distorts the dimming pattern during exposure of the central phosphor.

본 발명에서는 시프팅렌즈에 대응하는 웨지렌즈를 중앙 형광체의 노광시 정합시키도록 함으로써 방형의 정확한 노광패턴을 얻도록 하였다.In the present invention, the wedge lens corresponding to the shifting lens is matched at the time of exposure of the central phosphor to obtain a square exposure pattern.

Description

칼라브라운관의 노광방법Exposure method of color cathode ray tube

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is a trivial issue, I did not include the contents of the text.

제3도는 시프링렌즈를 통한 R, G, B 보정의 원리를 보이는 기구도, 제4도는 종래 노광방법에 의한 문제점과 종래의 해결방법을 보이는 평면도, 제5도는 본 발명 방법을 구현하는 노광기구를 보이는 단면도이다.FIG. 3 is a plan view showing the principle of R, G and B correction through the shifting lens, FIG. 4 is a plan view showing a conventional exposure method and a conventional solution, Fig.
