Abstract: This invention relates to a cathode ray tube having a funnel in the shape of a reverse curvature designed to improve the strength for the glass manufacturing process and test specification. In the present invention, a reverse radius is applied to the whole of the rear-side glass, which is the funnel, of the cathode ray tube. Therefore, the cathode ray tube has a high degree of strength for vacuum and a low weight, so that it can have a wide angle of the electric beam in accordance with the enlargement and the flattening plane of the cathode ray tube. The cathode ray tube that has the funnel in the shape of the reverse curvature comprises: a yoke on which a deflection coil is placed; and a body part that extends from the yoke toward an opening terminal attached to the panel. The center of a curvature in the yoke is located outside of the cathode ray tube; the center of a curvature in the body part extending from the yoke is located outside of the cathode ray tube; and the center of the curvature in the vicinity of the opening terminal of the body part is located inside of the cathode ray tube. Therefore, an inflection point is located in the body part in the vicinity of the opening terminal.

Abstract: A picture display device comprising a cathode ray tube (1) with an elongated display screen (8) and a deflection system (9) is described. The deflection power is reduced by two means. The deflection system (9) is arranged to scan the lines in the direction of the short axis (22) of the display screen (8), and the cone portion (3) of the cathode ray tube (1) has an elongated cross-section (54) whose aspect ratio is larger than or equal to the aspect ratio of the display screen (8), thereby enabling the deflection system (9), and in particular the line deflection subsystem (12), to be positioned closer to the electron beam envelope (51), which reduces magnetic losses.

Abstract: Disclosed herein is a panel for wide-angle flat cathode ray tubes. The panel includes a face part formed at the front part thereof for displaying a picture, a skirt part having a seal edge joined with the funnel, and a blend round part connected between the face part and the skirt part. On the assumption that the compression stress of a center part, which is the center region of the face part, is σ1, and the compression stress of an edge part, which is the edge region of the face part adjacent to the blend round part, is σ2, the panel is constructed such that the following inequality is satisfied: 1.5≦σ2/σ1≦2.33. Consequently, the present invention has the effect of satisfying the safety of the explosion-resistance characteristic and compensating for the reduction of vacuum strength, which is caused when the deflection angle of the cathode ray tube is increased and the panel is flattened.
