Patent number: 6703773Abstract: A tension mask frame assembly for a color cathode-ray tube, the assembly including a tension mask and a frame, is provided. The tension mask has a plurality of strips isolated from each other at predetermined intervals on a thin plate to form slots, and tie bars for partitioning slots at a predetermined pitch interval by connecting adjacent strips to each other. The frame has a pair of support members for supporting the longer sides of the tension mask, a pair of elastic members, the ends of which are connected to both ends of each of the support members so that the support members are isolated from each other a predetermined distance, and a reinforcing member having both ends coupled to both ends of the exterior side surface of each of the support members and its center portion contacting with the exterior side surface of each of the support members, the reinforcing member for elastically restoring the support members in a direction where a tensile force is applied to the strips.Type: GrantFiled: April 17, 2001Date of Patent: March 9, 2004Assignee: Samsung SDI Co., Ltd.Inventors: Kuen-dong Ha, Jong-in Jeong, Gui-bae Kim

Patent number: 6577051Abstract: A flat cathode ray tube is provided. The flat cathode ray tube includes a shadow mask having a plurality of electron beam holes, a shadow mask frame having multiple-layered support members continuously connected, for supporting the shadow mask, and an inner shield connected to the shadow mask frame. The support member for supporting a shadow mask is solidified by forming multiple-layer laminates. Also, mobility is provided to the longer sides of the shadow mask, thereby easily applying a tension to the shadow mask.Type: GrantFiled: April 9, 2001Date of Patent: June 10, 2003Assignee: Samsung SDI Co., Ltd.Inventors: Yong-Geol Kwon, Gui-Bae Kim
