| description | PROBLEM TO BE SOLVED: To provide the heater heat generating circuit and a heat generating method for speedily heating a heater to a normal temperature without preliminary heating. SOLUTION: A voltage generation means 20 generating voltage higher than rated voltage applied to the heater 24 of the cathode-ray tube 23 is provided. When the power of a unit is turned on and when power is applied to the heater and heat is generated at a power-on mode in accordance with a DPMS(display power management signaling) system, an instantaneous heating signal generation means 21 generate a driving pulse signal during time which is previously set at an initial stage. High voltage generated in the voltage generation means 20 is applied to the heater by an initial heating means 22 so as to generate heat during time when the driving pulse signal is generated. When time which is set elapses and the driving pulse signal is interrupted, high voltage generated in the voltage generation means 20 is dropped to rate voltage by a voltage drop means R21 and it is applied to the heater. |
