Patent number: 6072270Abstract: In a shadow mask employed as a color selection electrode in a multi-electron beam color cathode ray tube (CRT), the surface area of the mask is reduced by increasing the length of the individual elongated beam passing apertures, or slots, while reducing the ratio of the width of the bridge portion of the mask between adjacent apertures to the length of the aperture. Increasing the length of the apertures while reducing the ratio of bridge width to aperture length reduces the surface area of the mask upon which energetic electrons are incident resulting in a corresponding reduction in thermal deformation, or doming, of the shadow mask. Reduction in shadow mask doming results in reduced landing shift of the electron beams incident on phosphor elements disposed on the inner surface of the CRT's display screen for improved video image brightness and color purity. More specifically, in a shadow mask having a thickness in the range of 0.12-0.Type: GrantFiled: June 22, 1998Date of Patent: June 6, 2000Assignee: Chunghwa Picture Tubes, Inc.Inventors: Yu-Shin Hu, Ching-Hsiang Tseng, Kuo-Cheng Chen

Patent number: 5990607Abstract: A shadow mask, or color selection electrode, in a color cathode ray tube (CRT) is in the form of a thin metal foil and includes a large number of apertures through which electron beams are directed onto the phosphorescent coating on the CRT's display screen for forming a video image. The apertured shadow mask is also used with a light source during CRT manufacture to form a large number of spaced phosphor elements in the phosphorescent coating. Ideally, all of the beam passing apertures and phosphor elements are circular in cross-section, but the shadow mask is stretched and maintained under high tension when mounted in the CRT causing some of the apertures, particularly those adjacent its four corners, to also become stretched and assume an oval shape.Type: GrantFiled: July 14, 1998Date of Patent: November 23, 1999Assignee: Chunghwa Picture Tubes, Ltd.Inventors: Ching-Hsiang Tseng, Wen-Chi Chen, Kuo-Cheng Chen
