摘要： Self-converging cathode ray tube with a deflection angle that is greater than 110°. The tube comprises a front panel supporting a luminescent screen surrounded by a flange perpendicular to the panel, the internal surface of the said panel being defined by radii of curvature Rdi along the diagonal, Rxi along the major axis and Ryi along the minor axis such that:
- 4 ≥ Rdi/d ≥ 2
- 0.8 ≥ Ryi/Rdi ≥ 0.4
- 1≥ Rxi/Rdi ≥ 0.7
Hence, the geometric distortion of the picture engendered by the self-converging deflection device is minimized, while enabling the shadow mask equipping such a tube to be less sensitive to thermal interferences.
