| Zusammenfassung: | The invention concerns cathode ray tubes whereof the front surface and/or the angle of deflection is greater than 110. The tube comprises: a front panel supporting a luminescent display surrounded by a skirt perpendicular to the panel, said panel being defined by: a thickness t at one corner of the display; a distance t1 between the corner of the display and the free edge of the skirt; a funnel-shaped rear part, whereof the flared free edge is spaced apart by a distance t2 from the tube reference line. The tube is characterized in that the values t, t1, t2 are selected such that the ratio A = . |
