Abstract: The  ging  of  fluorescent  display  tube   comprises:   (A) evaporating moisture, which is contained  in  electrodes,  for  25 mins with a heating rate of 10 deg.C/min and a peak temperature of 200 deg.C while emitting the vapor out of the tube; (B) activating the filament by K decomposition while cooling the temperature down to 150 deg.C for 5 mins with a cooling rate of 10  deg.C/min;  and (C) thermally  decomposing  hazardous  components  contained   in electrodes by applying 1-1.2 times the  working  voltage  to  each electrode. The above method can enhance productivity and cut  down production cost by reducing energy requirement and process time.
