Abstract

본 발명은 음극선관의 새도우마스크 상에 형성되는 어퍼처가 불균일한 형상으로 가공되고 규칙적으로 배열되는 어퍼처를 지닌 새도우마스크에 관한 것이다. 본 발명은 새도우마스크(13)에 형성된 무수한 어퍼처(S)를 통해 판넬(11)의 형광면으로 전자빔을 주사하는 음극선관 조립체에 있어서: 상기 어퍼처(S)는 새도우마스크(13) 상에서 배치되는 위치에 따라 그 형상을 달리하고, 동시에 그 상부에칭면(Su)의 수평경사폭(Ha)(Hb) 및 수직경사폭(Va)(Vb)도 변화되고, 이러한 어퍼처(S)들은 새도우마스크(13)의 중앙에 대하여 전체적으로 점대칭으로 되는 규칙적인 배열을 지닌다. 따라서, 본 발명은 불균일한 형상으로 가공되고 규칙적으로 배열되는 어퍼처(S)를 사용함으로써, 음극선관의 판넬에 도달되는 전자빔의 찌그러짐을 보상하여 음극선관의 해상도를 향상시킬 수 있는 효과가 있다.The present invention relates to a shadow mask having apertures formed on a shadow mask of a cathode ray tube which are processed into an irregular shape and arranged regularly. The present invention provides a cathode ray tube assembly that scans an electron beam to a fluorescent surface of a panel 11 through a myriad of apertures S formed in a shadow mask 13. The aperture S is disposed on a shadow mask 13. The shape varies depending on the position, and at the same time, the horizontal inclination width Ha (Hb) and the vertical inclination width Va (Vb) of the upper etching surface Su are also changed, and these apertures S are shadow masks. It has a regular arrangement of point symmetry as a whole with respect to the center of (13). Therefore, the present invention has the effect of improving the resolution of the cathode ray tube by compensating for the distortion of the electron beam reaching the panel of the cathode ray tube by using the apertures S that are processed into a non-uniform shape and arranged regularly.

Description
