Abstract

본 발명은 음극선관용 패널 글라스에 관한 것으로서, 일정한 길이를 가진 대각유효반경과 일정한 에스팩트비를 이루며 공칭의 인치로 구성된 음극관용 패널 글라스에 있어서, 상기 에스팩트비를 이루는 패널 글라스의 내면 곡률이 단축, 장축, 대각축으로 형성되고, 상기 단축은 장축보다 크고, 단축은 대각축보다 크며, 상기 장축은 대각축과 같도록 곡률이 형성되어, 외면의 평판화에 의한 화상의 비틀림과 주변화상의 독취각, 화상의 반사 및 주변화상의 찌그러짐등을 개선하여 화상의 시인성을 향상시킬 수 있도록 한 것이다.The present invention relates to a panel glass for cathode ray tube, comprising a nominal effective radius having a constant length and a constant aspect ratio, in the cathode glass panel glass composed of nominal inches, the inner surface curvature of the panel glass forming the aspect ratio is shortened , Long axis, diagonal axis, the short axis is larger than the long axis, the short axis is larger than the diagonal axis, the long axis is formed such that the curvature is equal to the diagonal axis, the distortion of the image due to the flattening of the outer surface of the image It is to improve the visibility of the image by improving the smell, reflection of the image and distortion of the surrounding image.

Claims (1)

일정한 길이를 가진 대각유효반경과 일정한 에스팩트비를 이루며 공칭의 인치로 구성된 음극관용 패널 글라스에 있어서, 상기 에스팩트비를 이루는 패널 글라스의 내면 곡률이 단축, 장축, 대각축으로 형성되고, 상기 단축은 장축보다 크고, 단축은 대각축보다 크며, 상기 장축은 대각축과 같도록 곡률이 형성된 것을 특징으로 하는 음극선관용 패널 글라스.In a panel glass for a cathode tube having a nominal effective radius having a constant length and a nominal aspect ratio, the panel glass constituting the aspect ratio has a short curvature, a long axis, and a diagonal axis. Silver is larger than the major axis, the minor axis is larger than the diagonal axis, the long axis is a cathode ray tube panel glass, characterized in that the curvature is formed to be equal to the diagonal axis. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
