ABSTRACT:
A display device includes an evacuated envelope having a mosaic phosphor screen deposited on a front wall. A substantially rectangular frameless shadow mask having mounting means extending from two oppositely disposed edges of the shadow mask is in spaced, parallel relation to the screen. A shadow mask suspension system includes at least two mutually parallel support bars disposed on the front wall beyond the screen area. Shadow mask mounting means slots are in the distal surface of the support bars. A locking member engages each of the support bars to retain the mounting means within the slots.
