ABSTRACT:
An improved cathode-ray tube includes an envelope comprising a faceplate panel, a funnel and a neck. The faceplate panel includes a transparent rectangular faceplate having a cathodoluminescent screen on an interior surface thereof. The faceplate has a vertical minor axis and a horizontal major axis. The improvement comprises the thickness of the faceplate being less near the ends of at least one of the major or minor axes than at its center, whereby the viewing angle in at least one direction is increased. In a preferred embodiment, the thickness of the faceplate increases from center-to-edge along its minor axis and decreases from center-to-edge along its major axis.
