接または固着されている。 The light source tube 1 has transparent glass plates 1a and 1b arranged above and below, and side plates 1c, 1c', 1d, and 1d' made of glass, etc. arranged on both sides and both ends to make the inside airtight. It is sealed and filled with a rare gas or a metal vapor gas such as mercury to form a flat plate. The airtight space inside the light source tube 1 is created by two partition plates 2 made of glass arranged in parallel.
Three discharge paths 3a, 3b, and 3c are formed by a and 2b. At this time, the upper and lower ends of each of the partition plates 2a, 2b are in contact with or fixed to the upper and lower glass surfaces in a substantially airtight manner (a state in which the discharge does not affect adjacent parts and cause crosstalk).

５が封着されている。 Further, one end of the partition plates 2a, 2b is in contact with or fixed in an airtight manner to the side plate 1d serving as a stem surface, and the divided stem surfaces corresponding to each discharge path 3a, 3b, 3c are independently anodes. Electrodes 4a, 4
b, 4c are sealed. Partition plates 2a, 2b
The other ends are both open to the side plate 1d' on the opposite side, allowing the discharge paths 3a, 3b, and 3c to communicate in an open manner, and a cathode electrode 5 as a common electrode is sealed to the side plate 1d'. ing.

In this case, phosphors of different luminescent colors are coated on the corresponding upper and lower glass surfaces.For example, discharge path 3
A has a red phosphor 6a (europium-activated yttrium oxide (Y 2 O 3 ; Eu)), and a discharge path 3b has a green phosphor 6b (terbium-activated cerium magnesium aluminate (CeMgAl 11 O 19 ; Tb)). ), a blue phosphor 6c (europium-activated barium magnesium aluminate (BaMg 2 Al 16 O 27 ; Eu)) is deposited on the discharge path 3c.

に始動用スタータSTを接続してある。 Each anode electrode 4a, 4b, 4c is connected to a selection changeover switch SW (specifically, a transistor switch control for varying the duty) from a DC power supply DC via resistors Ra, Rb, and Rc as ballasts, respectively. The cathode electrode 5 is connected to the negative side of the DC power supply DC. Further, a starter ST for starting is connected between the anode electrode 5 and the non-power side.

選択切換スイツチSWが切り換えられ放電路３ａ
がスイツチオンすると放電路３ｂの場合と同様に
容易に放電し、赤色発光がなされる。 When the discharge path 3c is now switched on, the cathode electrode 5 is heated via the starting starter ST, and the starting starter ST is activated to apply a high voltage pulse between the anode electrode 4c and the cathode electrode 5, and the discharge path 3c is activated. Then, discharge is started and, for example, culorichromatic light is emitted. Subsequently, when the selection changeover switch SW is switched and the discharge path 3b is switched on, the discharge path 3b is turned on.
b immediately discharges (the cathode electrode 5 has already been heated and is fully ready to emit thermionic electrons, and the cathode electrode 5
Since the seeds of charge for discharge remain in the common space in the vicinity, the discharge path 3b is easily started (especially without the starter ST), and green light is emitted. Subsequently, the selection changeover switch SW is switched and the discharge path 3a
When switched on, the discharge path 3b easily discharges and emits red light.

ともできる。 When the selection changeover switch SW is switched at a high speed in this manner, the light emission of each color appears continuous and constant to the human eye, and stable discharge is achieved. In addition, by appropriately selecting each duty ratio, it is possible to freely obtain colors within the triangular chromaticity space of R, G, and B shown in Figure 9, and by temporally changing the duty ratio, one color can be obtained. It is also possible to continuously and smoothly change one luminescent color to another luminescent color.

It is possible to form a medium to large-sized display device by forming small flat picture elements of square to about 5 cm square and arranging them in a constant manner as shown in FIG.

で容易に実現できる。 In addition, since the discharge paths 3a, 3b, and 3c of the light source tube 1 are short, they can be easily controlled with a high DC power supply of 50 V or less, and the light source tube 1, which is a picture element, can be controlled in an X-Y matrix, and characters and pictures can be Displaying desired characters and pictures by inputting input information corresponding to the information can be easily realized using known means.
しかし、陰極電極５を第５図のように側面板１
d′の中央に取付けて単色のみの放電を行なつた場
合、例えば放電路３ａのみを放電させると陰極電
極５前面には放電により紫外線が生じる。 However, as shown in FIG.
When it is installed at the center of d' and discharges only a single color, for example, if only the discharge path 3a is discharged, ultraviolet rays are generated in front of the cathode electrode 5 due to the discharge.
この紫外線は大部分は放電路３ａ内に被着され

しまう。 Most of these ultraviolet rays excite the phosphors 6a deposited in the discharge path 3a and cause them to emit light, but since the ultraviolet rays originally diffuse freely, the phosphors 6b and 6c deposited in the other discharge paths 3b and 3c emit light. As a result, the light emitted from the phosphors 6b and 6c appears to be mixed with the light emitted from the phosphor 6a.
以上のように、この可変色放電灯では各単色の
みの発光及び同じ原因で２色のみの混合発光は色
純度が良好でないという欠点があつた。 As described above, this variable color discharge lamp has the disadvantage that the color purity is not good when emitting light of only each single color or when emitting mixed light of only two colors due to the same cause.

The present invention has been made in order to improve the above-mentioned drawbacks, and its purpose is to change the discharge paths, which were conventionally developed in parallel on a flat light source tube, into a multilayer structure so that the middle layer can be removed. The objective is to improve the color purity of a variable color discharge lamp by attenuating unnecessary light emission.

Embodiment 1 As shown in FIG. 1, two partition plates 2a and 2b made of glass, which conventionally divided the airtight space inside the light source tube 1 in parallel, are replaced by upper and lower glass plates 1a and 1b.
It is arranged in parallel to the Three layered discharge paths 3 are formed by these two partition plates 2a and 2b.
a, 3b, and 3c are formed. Partition plates 2a, 2
b is in contact with or fixed to the side plates 1c, 1c' and 1d in an airtight manner. Anode electrodes 4a, 4b, 4
C is the side plate 1d, and the cathode electrode 5 is the bottom glass plate 1.
It is arranged at the end of b. Each discharge path 3a, 3b,
As shown in FIG. 2, the phosphors 6a, 6b, and 6c of 3c are deposited so as to be offset by a uniform width so as not to overlap each other when viewed from the display section side (glass plate 1a side). The phosphors 6a, 6b, and 6c are phosphors that emit light of different colors. The lighting operation is the same as the conventional one, so the explanation will be omitted.

になる。その結果、不用な発光による色純度の低
下が改善されるのである。 Next, the operation will be explained. As described above, since the phosphors 6a, 6b, and 6c are shifted so that they do not overlap each other when viewed from the display side, the light generated by the phosphors 6a, 6b, and 6c is transmitted to the glass plate 1a and Phosphors 6a, 6b in partition plates 2a, 2b,
The light passes through the portion where the phosphor 6c is not attached, and high brightness is obtained with less attenuation caused by the other phosphors 6a, 6b, and 6c. In addition, when only one of the phosphors 6a, 6b, 6c emits light, the other phosphors 6a, 6b, 6c will also emit some light, but while it passes through each layer, the partition plates 2a, 2b etc. The target phosphor 6a is weakened by
Light emission other than 6b and 6c becomes almost negligible. As a result, the decrease in color purity due to unnecessary light emission is improved.

よい。 Furthermore, the lower the layer, the greater the transmission and absorption by the partition plates 2a, 2b, etc., so it is necessary to consider the emission intensity of the phosphor. For example, when using phosphors of three primary colors, select a blue phosphor for the top phosphor 6a, a red phosphor for the middle phosphor 6b, and a green phosphor for the bottom phosphor 6c. Good.
尚第２図に示すように仕切り板２ａ，２ｂの開
放部の位置のガラス板１ａは遮蔽手段７でマスク
しておいた方が望ましい。 As shown in FIG. 2, it is preferable to mask the glass plate 1a at the open portions of the partition plates 2a and 2b with a shielding means 7.

The phosphors 6a, 6b, and 6c of phosphors b and 3c are further divided and deposited. This improves color mixing on the display surface (glass plate 1a surface).
実施例 ３

This makes the widths of the phosphors 6a, 6b, and 6c non-uniform. For example, this can be corrected by increasing the coating width of a blue phosphor with low brightness. Alternatively, increasing the coverage of the green phosphor can improve the overall brightness and make the display easier to see.

Furthermore, since the discharge path is multi-layered, the size of the light source tube can be made smaller compared to the conventional parallel type, resulting in a dramatic improvement in resolution. In addition, because of the small size, the degree of freedom in the size of the display device that can be manufactured has increased compared to the conventional type.

くなるという効果を奏する。[Effects of the Invention] The present invention divides an airtight space formed inside a hexahedral light source tube into multiple layers in the depth direction from the display side using a partition plate, and forms independent discharge paths in each airtight space. One end of the discharge path is closed to provide each independent electrode, the other end of each discharge path is adjacent to each other so as to be in open communication with each other, and a common electrode is provided in the open communication space, and at least one surface of the inner surface of the tube body of each discharge path is provided. The phosphors of different luminescent colors were deposited on the partition plate, shifted by an equal width so as not to overlap when viewed from the direction perpendicular to the partition plate, and the discharge gas was sealed in the airtight space, so that the display surface Even if the ultraviolet rays emitted from the innermost discharge path cause phosphors in other discharge paths to emit unnecessary light, the intermediate layer can attenuate the unnecessary light emission, improving the color purity of the display surface and eliminating color bleeding. Moreover, since the discharge path is multi-layered, the size of the light source tube can be made smaller than that of a parallel type, and as a result, when used in a display device, the resolution can be dramatically improved. Moreover, there is an effect that the degree of freedom in the size of the display device is increased.

できるのである。 In addition, a partition plate is provided that divides the light source tube into multilayer discharge paths in the depth direction from the display side, and the phosphor adhered to the inner surface of the tube of each discharge path overlaps with each other when viewed from the direction perpendicular to the partition plate. Since the phosphors are shifted by an even width to prevent the phosphor from becoming a phosphor, there is no other phosphor in front of each phosphor when viewed from the display side, and the light from each phosphor is shifted by the other phosphor. Since almost no light is absorbed, the amount of attenuation can be reduced, and light can be emitted with high brightness.

ある。 In short, the inside of the light source tube is partitioned in the depth direction when viewed from the display side, and phosphors with different luminescent colors are applied to each partition plate in a staggered manner so that they do not overlap when viewed from a direction perpendicular to the partition plate. Therefore, even though the area of the display surface of the light source tube is relatively small, each phosphor can emit light with high color purity using one light source tube. The absence of partitions also improves color mixing. As a result, when used as pixels in a large color display device, it is possible to construct a screen with high resolution and excellent color tone.
