Abstract

PURPOSE:To prevent the pseudo luminescence of other portions than a luminescent display section for the specified picture element by providing side shielding electrodes in spaces formed by a control electrode and back plates between cathodes. CONSTITUTION:Side shielding electrodes 21 are located between a control electrode 14 and a substrate 1c and erected between cathodes 4 and 4. When the data signal and the scanning signal are applied to data electrodes 10 and back electrodes serving as scanning electrodes 12, thermoelectrons emitted from one cathode 4 normally flow and pass the opening section 15a of the control electrode 14. Thermoelectrons collide with the fluorescent character display section 8 corresponding to the opening section 15 and illuminate them. On the other hand, some of the thermoelectrons from the cathode 4 proceeding to other opening sections 15a are applied with the negative potential, for example, of the electrode 21 and deflected and pass the opening section 15a and guided to the display section 8. Thermoelectrons emitted from cathodes are all converged on the specified fluorescent character display section 8.

The on (positive) and off (negative) states of each data electrode 10 and the on (positive) and off (negative) states of each scan electrode 12 are controlled by the application timing of the data signal and the scan signal. There are four types of cases when the scan electrode 12 is on and off and the data electrode 10 is on and off (when the scan electrode 12 and data electrode 10 are both on, when the scan electrode 12 is on, and when the data electrode 111 is off, Scan electrode 12 is off, data electrode ■

(2) When the scanning electrode 12 is on and the data electrode 10 is off Since the data electrode 10 is formed near the cathode 4, the cathode 4 is most strongly influenced by the electric field of this data electrode 10. Therefore, in this case, the electric field near the cathode 4 becomes negative, thermionic emission from the cathode 4 is suppressed, and the fluorescent display section 8 does not emit light (FIG. 7 - ).

As explained above, the light emission of each fluorescent display section 8 is arbitrarily controlled by the combination of the potentials of the data electrode 10 and the scanning electrode 12. Here, the potentials of the data electrodes 10 and the scanning electrodes 12 are the same as those of the data signals D1 to D4 and the scanning signals 81 to S.

First, the data electrode 10 as shown in FIG. 6.7 is scanned [
Data signals D1 to D4 and scanning signals 81 to S4 as shown in FIG. 4 are applied to the back electrode spanning pole 1. Now, assuming that each of these electrodes 10, 12 has a polarity as shown in FIG. pass through. Therefore, thermoelectrons collide with the fluorescent display section 8 corresponding to this opening 15a, causing it to emit light. On the other hand, of the thermoelectrons from the cathode 4, those directed toward the other opening 15a are deflected in the direction of arrow R by receiving, for example, zero potential or negative potential of the side shield electrode 21, and pass through the opening 15a. Then, it is led to the same fluorescent display section 8 as described above through a regular route. Therefore, all the thermoelectrons emitted from the cathode 4 are absorbed into the designated fluorescent display section 8, causing it to emit light efficiently.
