Abstract: PURPOSE: To improve the brightness of a graphic fluorescent character display tube (display tube). CONSTITUTION: An external casing 1 is composed of a front plate 2, a back plate 3, and side plates 4. A plurality of stripe-like anodes 5 are formed in parallel one another in the inner face of the front plate 2. A plurality of linear control electrodes 9 are laid in parallel one another at right angles to the anodes 5 above the anodes 5. A cathode 11 is laid in the inner face of the back plate 3. The control electrodes 9 are made of an alloy containing 56% of Ni, 44% of Ti, and a slight amount of Cu and Co. Of the alloy, the elastic limit is 6%, the coefficient of thermal expansion is 110×10<-7> / deg.C. The conversion of the elastic limit into temperature gives 0.06/(110×10<-7> / deg.C)=5454 deg.C.  Tensile force is applied previously to the control electrodes to elastically expand the electrodes by necessary degree and fix the electrodes, so that no control electrode loosen even if the temperature of the control electrodes rises at the time of driving a fluorescent display tube. As a result, driving voltage for the control electrodes of the display tube is not limited practically. The brightness of the display tube increases proportionally to about 2.7 power of driving voltage of the control electrodes. Consequently, a display tube with high brightness can be provided and control electrodes are prevented from vibrating.
