BEST MODE FOR CARRYING OUT THE INVENTION

Embodiment 1 FIG. Hereinafter, a first embodiment of the present invention will be described with reference to the drawings. 1A and 1B are views showing a display element as a display unit of the gas discharge display device of the present invention, wherein FIG. 1A is a front view, FIG. 1B is a cross-sectional view taken along line II, and FIG. 1C is a rear view.
In the figure, 11 is a display element, 12 is a fluorescent lamp as a light-emitting unit, which is made of a derivative cylindrical container made of a glass bulb having a portion with a different diameter in the axial direction, and in which a rare gas is sealed. 12a is a fluorescent lamp 12
A large-diameter portion, 12b is a small-diameter portion of the fluorescent lamp 12, 12c is an internal electrode inserted into the fluorescent lamp 12 from an end face portion on the small-diameter portion 12b side, 12d is an external electrode provided on an outer surface of the large-diameter portion 12a, Reference numeral 12e denotes a phosphor layer formed on the inner surface of the large-diameter portion 12a, and 12f denotes a light-transmitting light output portion provided at the tip of the large-diameter portion 12a.

Reference numeral 13 denotes an upper substrate in which holes 14 for inserting the small-diameter portions 12b of the fluorescent lamp 12 are formed in a matrix, and 15 denotes a fixing member 16 for fixing the internal electrodes 12c of the fluorescent lamp 12 in a matrix. The arranged lower substrates 17 are spacers for holding the upper substrate 13 and the lower substrate 15 in parallel at a predetermined distance.

Reference numeral 18 denotes a wiring pattern as a wiring material for connecting the external electrodes 12d of the fluorescent lamps 12 formed on the upper substrate 13 in a column direction, and 19 denotes a fluorescent lamp 12 formed on the lower substrate 15. A wiring pattern 20 as a wiring material for connecting the internal electrodes 12c in the row direction, and a wiring pattern 20 formed on the upper substrate 13 and the fluorescent lamp 1;
This is a first connection member for connecting the two external electrodes 12d.

Further, reference numeral 21 denotes a second connection member for supplying a signal for driving the fluorescent lamp 12 to a wiring pattern 18 formed on the upper substrate 13, and reference numeral 22 denotes a lower substrate 15.
A hole 23 for supplying a signal for driving the fluorescent lamp 12 to a wiring pattern 19 formed on the lower substrate 15 is provided. This is a third connection member.

Next, the operation will be described. A drive signal having a waveform shown in FIG. 2A is applied to the wiring pattern 18, and a drive signal having a waveform shown in FIG. 2B is applied to the wiring pattern 19, for example. . As a result,
A drive signal having a waveform shown in FIG. 2C is applied between the internal electrode 12c and the external electrode 12d of the fluorescent lamp 12, and controls writing, sustaining, and erasing of discharge.

Here, the peak value of each drive signal shown in FIGS. 2A and 2B is several hundred volts. Therefore, the insulation distance required between the two drive signals requires an insulation distance of about 1 kV and a creepage distance of several mm or more. This is a wiring pattern formed on the same substrate.
If it is intended to realize this, the arrangement interval of the fluorescent lamps 12 cannot be reduced, and as a result, it is impossible to arrange the fluorescent lamps 12 at high density.

On the other hand, FIG. 1 according to Embodiment 1 of the present invention
In the case of the structure shown in FIG. 7, since the wiring pattern 18 and the wiring pattern 19 are formed on different substrates,
Even when the interval between the fluorescent lamps 12 is reduced, the required insulation distance can be secured by adjusting the height of the spacer 17. Further, the height of the spacer 17 is closely related to the length of the small diameter portion 12b of the fluorescent lamp 12, but the length of the small diameter portion 12b is determined in Japanese Patent Application No. 7-14630.
As described in No. 8, the driving signal applied between the internal electrode 12c and the external electrode 12d of the fluorescent lamp 12, that is, the driving signal shown in FIGS. 2A and 2B is required. There is no problem because it is determined so that the insulation distance can be secured.

In FIG. 1, the upper substrate 13 and the lower substrate 1
Although an example of the printed wiring board on which the wiring patterns 18 and 19 are formed is shown as 5, it is needless to say that the same effect can be obtained even with an insulating substrate provided with an appropriate wiring material.

Further, as shown in FIG.
Numeral 0 has a cylindrical portion 20a fitted to the external electrode 12d, and has a wiring pattern 18 on the upper substrate 13 and a fluorescent lamp 1
The second external electrode 12d can be easily connected.

Further, the second connecting member 21 is connected to the lower substrate 15
When the display element 11 is disposed outside the
It is necessary to consider the insulation between the second connecting member 21 and the lower connecting member 21. However, the lower substrate 15 is provided with a hole 22 for allowing the second connecting member 21 to penetrate therethrough so that the second connecting member 21 can be penetrated. When the fluorescent lamps 12 are arranged vertically, it is not necessary to consider the insulation between the second connection members 21 of the adjacent display elements 11, and as a result, the fluorescent lamps 12 can be arranged at a high density.

Embodiment 2 FIG. 4 shows Embodiment 2 of the present invention, and shows an example in which a second cylindrical portion 20b fitted to the small-diameter portion 12b of the fluorescent lamp 12 is formed in the first connecting member 20. The applicants have disclosed in Japanese Patent Application No. 7-146308 that the auxiliary discharge in the small-diameter portion 12b facilitates the generation of a main discharge that causes the fluorescent lamp 12 to emit light. , The external electrode 12d and the second external electrode provided on the small-diameter portion 12b are driven by the same signal.
The external electrode can be easily realized by forming the second cylindrical portion 20b on the first connecting member 20 as shown in FIG. As a result, it is possible to stably control the discharge of the fluorescent lamp 12.

Embodiment 3 FIG. 5 shows a third embodiment of the present invention, in which the fixing position 20c of the first connecting member 20 adjacent to the column direction to the upper substrate 13 is set at the center of the hole 14 for inserting the small diameter portion 12b of the fluorescent lamp 12. 18 against each other
The case where the position is rotated by 0 ° is shown. Usually, in an array type display device in which a display screen is configured by arranging a plurality of display elements as display units having a finite size, a clearance for the arrangement is required between the respective display elements. On the other hand, it is desirable that the interval between the light-emitting units is constant. As a result, a hole 14 for inserting the small-diameter portion 12b formed on the uppermost edge on the upper substrate 13 and a hole 14 for inserting the small-diameter portion 12b are formed. The distance d between the hole 14 and the substrate end of the upper substrate 13 is, as shown in FIG.
Is shorter than の of the distance P between the holes 14 for inserting the holes.

Here, as shown in FIG.
When the fixing position 20c of the connecting member 20 to the upper substrate 13 is fixed (identical) to the center of the hole 14 for inserting the small-diameter portion 12b of the fluorescent lamp 12, the uppermost edge of the upper substrate 13 Fixed position 20 of the first connecting member 20 disposed at
c is a small-diameter portion 12b formed on the uppermost edge of the upper substrate 13.
It is necessary to set the gap between the hole 14 for inserting the small-diameter portion 12b and the substrate end of the upper substrate 13 immediately near the hole 14 for inserting the small-diameter portion 12b. In this case, the hole 1 for inserting the small diameter portion 12b
4 has a margin P, and a hole 14 for inserting the small-diameter portion 12b formed on the uppermost edge of the upper substrate 13 and a hole 14 for inserting the small-diameter portion 12b, which are located on the upper substrate 13 Of the first connection member 20 in the above-described portion as the distance d from the end of the substrate.
There is no problem if the distance required to set the fixed position 20c of the fluorescent lamp 12 is sufficient (the case shown in FIG. 7A), but in order to further increase the density of the arrangement of the fluorescent lamps 12, When the distance P between the holes 14 for inserting the 12b is further reduced (in the case shown in FIG. 7B), the fixing position 20c of the first connection member 20 is set in this portion. It will be difficult.

Therefore, as shown in FIG. 5, the first connecting members 20 adjacent to each other in the column direction
c is a hole 1 for inserting the small diameter portion 12b of the fluorescent lamp 12.
Assuming that the position is rotated by 180 ° with respect to the center of the hole 4, a hole 14 for inserting the small diameter portion 12 b formed on the uppermost edge of the upper substrate 13 and a hole for inserting the small diameter portion 12 b It is no longer necessary to set the fixed position 20c of the first connection member 20 between the display element 11 and the substrate end of the latest upper substrate 13 of the display element 14.

When the first connection member 20 is fixed to the upper substrate 13 at the position shown in FIG. 5 in order to realize the display element 11 in which the fluorescent lamps 12 are arranged at a higher density, for example, in the direction of the wiring pattern 18 When this fixed position is taken between the first connecting members 20 adjacent to each other in a direction perpendicular to the wiring pattern 18, different driving signals are applied to the first connecting members 20 adjacent in the direction perpendicular to the direction of the wiring pattern 18. Is applied, it is necessary to secure an insulation distance between adjacent fixed positions. This is an obstacle to arranging the fluorescent lamps 12 at high density.

Therefore, as shown in FIG.
5 on a straight line connecting a hole 14 for inserting the small diameter portion 12b of the fluorescent lamp 12 in the direction of 8 in the position shown in FIG.
When the connection member 20 is fixed to the upper substrate 13, the same drive signal is applied to the first connection member 20 adjacent in the direction of the wiring pattern 18. It is not necessary to consider the insulation of the fluorescent lamp 12, and the high-density arrangement of the fluorescent lamps 12 can be easily performed.
