Abstract

본 발명은 칼라 브라운관의 형광면 형성방법에 관한 것으로, 특히 R,G,B안료필터층 아래에 안료 잔사 방지막을 사용하여 상기 R,G,B안료입자가 타색위치에 남지 못하게하여 칼라 브라운관의 콘트라스트 및 휘도를 향상시키는데 적당하도록 한 칼라 브라운관의 형광면 형성방법에 관한 것이다.The present invention relates to a method for forming a fluorescent surface of a color CRT, in particular, by using a pigment residue prevention layer under the R, G, B pigment filter layer so that the R, G, B pigment particles do not remain in the other color position, and thus the contrast and luminance of the CRT. The present invention relates to a method for forming a fluorescent surface of a color CRT that is suitable for improving the efficiency of the CRT.

본 발명의 상기 목적을 달성하기 위한 칼라브라운관의 형광면 형성방법은 판넬내면에 형광면을 포함하는 칼라음극선관에 있어서, 상기 판넬상에 블랙 매트릭스를 형성하는 제1공정과, 상기 판넬전면에 제1프리코트막과 제1색안료막을 차례로 증착하고 제1칼라화소영역에만 남도록 제1프리코트막 및 제1색안료막을 패터닝하는 제2공정과, 상기 전면에 제2프리코트막과 제2색안료막을 차례로 증착하고 제2칼라화소영역에만 남도록 제2프리코트막 및 제2색안료막을 패터닝하는 제3공정과, 상기 전면에 제3프리코트막과 제3색안료막을 차례로 증착하고 제3칼라화소영역에만 남도록 제3프리코트막 및 제3색안료막을 패터닝하는 제4공정과, 상기 제1칼라화소영역에 제1형광체막을 형성하는 제5공정과, 상기 제2칼라화소영역에 제2형광체막을 형성하는 제6공정과, 상기 제3칼라화소영역에 제3형광체막을 형성하는 제7공정을 포함하여 이루어짐을 특징으로 한다.A method for forming a fluorescent surface of a color brown tube for achieving the above object of the present invention is a color cathode ray tube including a fluorescent surface on an inner surface of a panel, the method comprising: forming a black matrix on the panel; and a first free surface on the front surface of the panel. A second step of depositing a coating film and a first color pigment film in sequence and patterning the first precoat film and the first color pigment film so as to remain only in the first color pixel region; and a second precoat film and a second color pigment film on the entire surface. A third step of patterning the second precoat film and the second color pigment film so as to deposit them sequentially and remaining only in the second color pixel region; and then depositing a third precoat film and a third color pigment film on the entire surface, and then in the third color pixel region. A fourth process of patterning a third precoat film and a third color pigment film so as to remain only, a fifth process of forming a first phosphor film in the first color pixel region, and a second phosphor film in the second color pixel region 6th process Characterized the yirueojim including a seventh step of forming the first film a third color phosphor in the third pixel region.
