Abstract
An improved front assembly for a color cathode ray tube having a tension foil shadow mask is disclosed. The faceplate of the tube has on its inner surface a centrally disposed phosphor screen surrounded by a peripheral sealing area adapted to mate with a funnel. A shadow mask support structure is provided for securing a shadow mask in tension on the structure and spacing the shadow mask from the screen. The support structure includes an undulated strip defining a bottom sinuous edge for securing the support structure to the faceplate and a top sinuous edge for securing the shadow mask to the support structure. A cap may be provided for securement to the top sinuous edge of the undulated strip to provide a land for securing the shadow mask to the support structure.
