  • Color cathode ray tube with improved shadow mask mounting system
    Patent number: 5982085
    Abstract: An apertured shadow mask directs electron beams toward phosphor elements on the inside surface of the face plate of a CRT. The mask is fixed to a rectangular frame having corner brackets connected by light-weight diaphragm strips and resilient plates molded to the brackets. The resilient plates have holes toward the distal ends thereof which engage pins embedded in a skirt surrounding the face plate. The plates are precipitation hardened stainless steel having a thickness of 0.20 mm to 0.30 mm and provide sufficient spring force to retain the mask and frame as well as the internal magnetic shield which is fixed to the corner brackets by clips.
