Title: Cathode ray tube device
Inventor: SAKUMA TOSHIHARU
IPC: H04N3/20
Filed: 1991-03-07
Abstract: PURPOSE:To prevent the burning of an electron beam, to extend the service life of the cathode ray tube, and to improve the reliability by delaying the attenuation of a grid voltage at the time when the device power source is cut off. CONSTITUTION:A voltage G1 is supplied to a main voltage circuit 1 from an FBT, and also, a voltage VG2 being higher than the voltage VG1 is applied to a sub-voltage circuit 2. In such a state, when a breakdown voltage of a Zener diode 18 is set to a value being higher than a difference between VG2 and VG1, no current flows in a resistance 19 unless VG2 and VG1 are varied in a state of device power source 'ON', a transistor TR 20 maintains a turn-off state, and an output of the circuit 2 is detached from a grid and becomes no- load. In this state, when the power source is disconnected and becomes a turn-off state, the voltage VG1 is attenuated by a time constant determined by a capacitor 12 and a resistance 13. On the other hand, the TR 20 is turned off and the voltage VG2 is scarcely attenuated. Subsequently, when VG1 is attenuated and a difference between VG2 and VG1 becomes higher than the breakdown voltage of the diode 18, a current flows in the diode 18, and the grid voltage VG is attenuated slowly.
