る欠点を治する。If a conventionally known glass material is used for this pillar 42, the withstand voltage will deteriorate over time and sufficient insulation will not be maintained. It is necessary to further process the glass into a rod shape, and it is expensive.A support column proposed in Japanese Patent Application Laid-Open No. 60-70648 is shown in FIG. The panel shown here is a panel in which a container is divided into a number of modules by a reinforcing partition wall 51. This reinforcing partition wall 51 is made of an electrically insulating material and has a deflection electrode 52 in the middle, and a display screen 5.
3, and this Japanese Patent Application Publication No. 3 is characterized by the fact that a V-shaped groove is provided on the outer side of the container to prevent the shadow of the reinforcing partition wall from appearing on the screen. Teimo Kone also same as above mentioned JP-A-53 +4+57: (
, a sufficiently high voltage can be applied and the t-14 Jg point is applied.Furthermore, this Japanese Patent Application Laid-Open No. 1987-70648 shows that gas discharge panels can also be applied, along with examples. The use of reinforcing partitions made of the electrically insulating material in gas discharge panels overcomes the disadvantage of impaired discharge stability.

The present invention is intended to solve the above-mentioned problems.Means for solving the problems In order to solve the problem (ζ), the light emitting means constructed in the container and the means such as the control means for controlling the amount of light emitted from the light emitting means are used. ) By using the above-mentioned means, a current always flows stably between the two means, and it is possible to prevent the occurrence of electric discharge. No matter how high the potential difference is, it is not a matter of never passing current as in the past and trying to insulate it. It is possible to prevent the occurrence of electric discharge due to the generation of a potential gradient.An embodiment of the present invention will be explained using Fig. 1 @ Fig. 2.
FIG. 2 shows a block diagram of the entire panel as an embodiment of the present invention. A back electrode 10 and a face plate 11 which also serves as a container and is equipped with a light emitting means are arranged in a vacuum container.
In between, multiple filament cathodes 12. Electron beam control electrode groups 13 including electrodes for controlling electron beams are arranged in rows and columns to form the entire panel. Electron beams are emitted from the filament cathode 11 in a shower shape by the voltages applied to the back electrode 10 and the 011it pole in the electron beam control electrode group 13. The electron beam is controlled by applying a display signal voltage to each of the G2 electrodes, which are divided into a plurality of rows. Furthermore, the 03 electrode, which is divided into a plurality of columns, corresponds to one horizontal scanning line on the display screen. The electron beam is controlled by applying a voltage that allows the electron beam to pass through one row of electrodes, and a voltage that does not allow the electron beam to pass through the other row electrodes.A Furthermore, the G4 electrode adjusts the focus shape of the electron beam to ensure an appropriate spot. Sufficiently clear display can be achieved by emitting an electron beam on a phosphor surface with a diameter
A similar display can be made by using an electrode that deflects the electron beam.A more detailed embodiment of the present invention will be explained with reference to FIG. 1, which is an enlarged view of a main part of the panel of the above embodiment. Sumo No. 1 in Figure 1 Friend Figure 2 G3. Even if a part of the G4 electrode and face plate is shown enlarged, a black line 19, which is a non-luminescent material, is placed on the phosphor 21, and a thin film of aluminum is adhered on top of the phosphor 21. However, this thin aluminum film is omitted in FIG. 14 are regularly formed in a row so that each row corresponds to one horizontal scanning line. 4 G4 electrodes 15ζ are provided with columns 18 having a rectangular cross section on the side of the phosphor 20. Although not shown in the figure, pillars are randomly formed in the shape of dots between the G3 electrode and the 04 electrode.

。A voltage of 3 to 5 KV is applied to the thin aluminum film (not shown in the figure) on the surface of the phosphor 20. The size of one pillar 18 (
For example, if the width of the black line 19 is 100 μm, the length will be 300 μm in the line direction and 100 μm in the height direction.
In screen printing, a thickness (height) of about 100 μm is obtained by overprinting about 5 to 10 times, but a drying process is added between each printing. In the final stage, the pillar is completed by firing at about 450℃ for one step.
Furthermore, when firing is performed at approximately 300 to 550°C in a hydrogen atmosphere, a conductive film with a specific resistance of io"-to"Ω is formed on the surface of the pillar made of powdered glass mainly composed of PbO. 4Pd-Ag compound that transforms into a film that is also effective as a secondary electron emitting material Compound containing RuOs & Pt
Although it is possible to form pillars with the above specific resistance by screen printing even with compound adhesion containing the above, it is even worse to partially attach a secondary electron emitting material such as MgO to the surface by vapor deposition, etc. is also possible. Further, in forming the pillars of the 04 electrode 15 in the electron beam control electrode group, the pillars can be formed in the same manner as described above.A panel is manufactured with such a configuration, and vacuuming is performed in the latter half of the process. Container on the back side of the back electrode Back electrode Electron beam control electrode The face plates have a structure in which they are in contact with each other via supports 6. By using a secondary electron material between the G4 electrode and the phosphor surface, the electron beam current can be multiplied.It is also possible to make the beam even brighter. By screen printing the tip of the column into a conical shape and firing it thoroughly, the tip of the column can be made into a conical shape.Using this method,
When these cone-shaped pillars are used in rows and columns, the portions that touch each other are in point contact, and the current flowing between the electrodes is extremely small, resulting in a small amount of power consumption.

The effect is immeasurable, considering that if even one discharge were to occur, the thin aluminum film on the phosphor surface and the phosphor itself would scatter and become irreversibly destroyed, making it impossible to commercialize it.

４In addition, if the contact portion is configured as a point contact, less current flows there, which further reduces power consumption.A pillar is formed on the light emitting display surface as a contact portion that is convex from that surface. By doing so, the light emitting display surface can be
The pillars formed on the electrodes do not damage the electrodes, and a very clear display can be obtained. By forming the pillars, which are the contact parts, in rows or columns and configuring them so that they contact each other in a matrix shape, it is possible to display the display pixels sufficiently without impairing the image quality. Even if sufficient assembly latitude can be achieved, a fire can occur if the assembly is done without the need for proper assembly.By forming the contacting part with a secondary electron emitting material, a larger electron beam current can be taken and a brighter display can be produced. I can also do it again 2
By using glass as the secondary electron emitting material, it is possible to obtain secondary electron emission at a lower cost.By forming the contacting part using a printing method, it can be manufactured at a lower cost using a more complicated process. By using glass for the contacting part and manufacturing it through a reduction treatment process, it is possible to obtain a secondary electron emitting material at a lower cost4.
