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 upper, flattened ridge for securing the shadow mask to the support structure. A plurality of legs depend from the ridge and at least a series of the legs is flared outwardly from one side of the ridge to facilitate securing the support structure to the faceplate and to stabilize the support structure under the tension of the shadow mask.
