Description

칼라 브라운관의 노광방법Exposure method of color CRT

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

제1도는 본 발명에 쓰이는 노광장치의 개략도.1 is a schematic view of an exposure apparatus used in the present invention.

제2도는 본 발명에 의한 노광장치에서 광원 광량의 경시변화를 도시하는 그래프.2 is a graph showing changes over time of the light source light amount in the exposure apparatus according to the present invention.

Claims (1)

칼라 브라운관의 블랙 매트릭스 막의 제작공정에 있어서, 광원에서 발하는 광량을 수광소자로 측정하면서 노광함량 (광량×시간)을 제어하는 것과 함께, 상기 수광소자로 광량을 측정하여, 광원의 전원으로 피이드백하여 광원의 광량을 일정한 폭내에 유지하는 것을 특징으로 하는 칼라 브라운관의 노광방법.In the manufacturing process of the black matrix film of the color CRT, while controlling the exposure content (light quantity x time) while measuring the light amount emitted from the light source with the light receiving element, the light amount is measured with the light receiving element and fed back to the power source of the light source. An exposure method of a color CRT tube, wherein the amount of light of the light source is kept within a predetermined width. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
