Abstract

본 발명은 칼라 브라운관의 신규한 마스크 프레임을 개시한다. 종래에는 섀도우마스크에 도밍이 발생되면 바이메탈에 의해 마스크 프레임을 형광면측으로 전지시킴으로써 보상하였는데, 도밍보상이 늦고 부가적으로 국부적인 색순도열화부를 발생시키는 문제가 있었다. 본 발명에서는 프레임 상부의 지지부에 챙창판을 통해 섀도우마스크를 접합하여 도밍시 섀도우마스크를 사방으로 스트래칭하여 보상하도록 함으로써 국부적인 하질열화없이 신속한 도밍보상이 가능하도록 하였다.The present invention discloses a novel mask frame of a color CRT. Conventionally, when doming occurs in a shadow mask, the mask frame is compensated by bimetal to the fluorescent surface side, but the doming compensation is late and additionally, there is a problem of generating a local color purity deterioration part. In the present invention, the shadow mask is bonded to the support portion of the upper portion of the frame through the visor plate to allow the shadow mask to be stretched and compensated in all directions so as to compensate for the rapid doming without local degradation.
