Abstract

본 발명은 칼라필터를 가지는 칼라브라운관의 형광면을 형성하는 개선된 방법을 개시한다.The present invention discloses an improved method of forming a fluorescent screen of a color cathode ray tube having a color filter.

본 발명에서는 칼라필터가 패널의 페이스의 가장 전면에 위치하도록 하여 그 분산효과에 의해 색재현 특성을 향상시키도록 하였으며, 특히 형광체를 블랙매트릭스 전면에 형성하는 경우에는 고화질, 고위도의 달성이 가능하다.In the present invention, the color filter is positioned on the entire front side of the face of the panel to improve the color reproduction characteristics by the dispersion effect. In particular, when the phosphor is formed on the entire surface of the black matrix, high image quality and high latitude can be achieved.

Description

칼라브라운관의 형광면 형성방법Method of forming fluorescent screen 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.

제2도는 칼라 필터를 채용한 종래의 형광면의 구성을 보이는 확대 단면도, 제3도는 본 발명 방법에 의한 형광면의 구성을 보이는 확대 단면도들이다.FIG. 2 is an enlarged sectional view showing a configuration of a conventional fluorescent screen employing a color filter, and FIG. 3 is an enlarged sectional view showing the configuration of a fluorescent screen according to the inventive method.
