保できないこととなる。Such a DC-driven gas discharge display panel has a relatively simple structure as compared with an AC-driven gas discharge display panel, and has a reduced lighting pulse width of a discharge cell. This is advantageous in that halftone display can be realized relatively easily. On the other hand, since it does not have the so-called memory function of the AC drive type, even if it is necessary to continuously light a specific discharge cell, in fact, until the scanning order of the cathode corresponding to the discharge cell comes. During this time, it is turned off. of course,
Since the above scanning speed is relatively fast, it appears to the naked eye to be continuously lit, but when the number of discharge cells is increased with the enlargement of the display screen, the number of scans on the cathode side increases by that amount, The lighting pulse width per discharge cell must be shortened. As a result, a decrease in brightness and flicker of each discharge cell become noticeable. Further, since the brightness of each discharge cell cannot be sufficiently increased, a large number of gray scales for halftone display cannot be secured.

が持続し、記憶として残ることとなる。In order to solve this problem, there is a technique for adding a memory function to a direct current type gas discharge display panel. For example, in Japanese Patent Publication No. 52-28350,
There is disclosed a technique for adding a memory function to a DC-driven gas discharge display panel by utilizing a difference between a discharge starting voltage and a discharge sustaining voltage. In this method, a voltage between the discharge starting voltage and the sustaining voltage is applied between the anode and the cathode by using the voltage drop caused by the protection resistor, and the trigger voltage for starting the discharge is triggered by the trigger between the anode and the trigger. It is added between the cathode. As a result, electrons and ions were diffused into the space between the anode and the cathode by the discharge generated between the trigger electrodes, and a discharge was generated below the firing voltage in the space, and the trigger voltage was removed. Even after that, the discharge continues due to the sustaining voltage applied to the space and remains as a memory.

In addition to being provided for each discharge cell, it is necessary to arrange control electrodes for controlling the passage of electrons and ions, making the configuration relatively complicated.
There was a regret to increase the size.

成したことを特徴とする。In order to achieve the above-mentioned object, in a DC-driven gas discharge display panel according to the present invention, a plurality of anodes made of a transparent conductive material are arranged in parallel at a predetermined pitch on one surface side. A front substrate made of a transparent insulating material and a rear substrate made of an insulating material in which a plurality of cathodes are arranged in parallel at a predetermined pitch on one surface side are opposed to each other so that the electrodes of each substrate intersect at a predetermined distance. A discharge cell is formed at each intersection of the anode and the cathode, and a structure is provided in which a predetermined discharge gas is filled in an airtight container formed by sealing the peripheral edges of both substrates. While scanning in a divided manner, selectively applying a DC voltage to the anode in synchronization with the scanning on the cathode side, in a DC driven gas discharge display panel to generate discharge light emission in any discharge cell, Each of the above anodes,
At least, on one surface of the front substrate, a plurality of anode members arranged in parallel at a predetermined pitch, and on the surface of a transparent insulating film covering the terminal portion side of the anode member, the transparent insulating film is interposed therebetween. A plurality of anode members are arranged in parallel with each other so as to overlap the terminal portion side of the anode member and substantially along the same straight line, each terminal portion of each anode member is separately taken out and connected to a drive circuit, and A plurality of cathodes are divided into a plurality of cathode groups that intersect at least the exposed front end portion of each anode member, and the above-described scanning is performed for each cathode group.

が低下することとなる。The display brightness of the DC-driven gas discharge display panel is proportional to the pulse width of the voltage applied to each discharge cell, and this pulse width is inversely proportional to the number of scans on the cathode side. That is, if the number of scans on the cathode side increases, the scan time per cathode decreases, the pulse width of the applied voltage decreases accordingly, and the lighting time of one discharge cell decreases, so that the luminance decreases. .

させることができる。Therefore, as described above, each anode is composed of at least one anode member arranged in parallel at a predetermined pitch on one surface of the front substrate and a transparent insulating film covering the terminal side of the anode member. On the surface, a plurality of anode members are arranged in parallel with each other so as to overlap and be arranged in parallel along substantially the same straight line as the terminal portion side of the anode member with the transparent insulating film interposed therebetween.

や文字等のキャラクタ表示を実現することができる。Thus, each cathode 20 is sequentially scanned in a time-division manner through the row driver circuit for each cathode group to which each cathode 20 belongs. Then, by applying a DC voltage from the column driver circuit to the first anode member 22 to the fourth anode member 30 in synchronization with the scanning of the cathode 20, a discharge is generated in a desired discharge cell 32. Becomes possible. For example, at the moment when the cathode 20C-3 belonging to the third cathode group 20C is scanned, a voltage is applied to the third anode member 28-4 to generate a discharge in the discharge cell 32a. The visible light generated by this discharge is transmitted to the third anode member 2.
8, the first transparent insulating film 24, the first anode member 22, and the front substrate 12 are transmitted to be displayed outside. At the moment when the cathode 20A-3 belonging to the first cathode group 20A is scanned, a voltage is applied to the first anode member 22-4 to generate a discharge in the discharge cell 32b. The visible light transmitted through the first anode member 22 and the front substrate 12 is displayed outside. Therefore, by selectively performing the above-described voltage application based on the display data, it is possible to display a character such as an arbitrary figure or character on the surface of the front substrate 12.

果、１６〜６４階調の中間調表示も可能となる。As described above, the anodes are driven independently of each other, and are aligned on the same straight line when viewed from the display direction.
The first anode member 22 to the fourth anode member 30 and the cathode 20 side are also independently scanned.
Are divided into the cathode group 20A to the fourth cathode group 20D, so that the first DC-driven gas discharge display panel 10 can realize about four times improvement in brightness as compared with the conventional example. That is, the luminance of the DC-driven gas discharge display panel is proportional to the pulse width of the voltage applied to each discharge cell, and the pulse width is inversely proportional to the number of scans on the cathode side. As the number of scans on the cathode side increases, the scan time per cathode decreases, the pulse width of the applied voltage decreases accordingly, and the lighting time of one discharge cell decreases, resulting in a decrease in luminance. Therefore, if all the cathodes are grouped into four groups and each is scanned separately, the scanning time per cathode can be secured four times, and the pulse width of the applied voltage can be quadrupled. . As a result, the lighting time of the discharge cell 32 is quadrupled, so that the display luminance is quadrupled. This also means that the total number of the cathodes 20 can be quadrupled while maintaining the conventional brightness, so that the display area of the gas discharge display panel can be increased. Further, as the lighting pulse width of each discharge cell 32 increases and the display luminance is improved as a whole, halftone display of 16 to 64 gradations becomes possible.

A gas discharge display panel for full-color display of 0 dots × 640 dots in width was used. In the case of full color display, generally, as shown in FIG. 5, a discharge cell R for red light emission, discharge cells G1 and G2 for green light emission, and a discharge cell B for blue light emission

なる。Although not shown, the first anode member 22,
The respective terminal portions of the second anode member 23 and the third anode member 28 are separately taken out and connected to a column driver circuit for voltage application. The terminal of each cathode 20 is connected to a scanning low driver circuit. Thus, each cathode 20 is sequentially scanned in a time-division manner for each group to which the cathode 20 belongs via the row driver circuit. By selectively applying a DC voltage to the first anode member 22 to the third anode member 28 in synchronization with the scanning of the cathode 20, a discharge can be generated in a desired discharge cell 32.

The second DC-driven gas discharge display panel 40 is about three times smaller than the conventional example because the first and second cathode groups are divided into a first cathode group 20A to a third cathode group 20C which are independently scanned. The brightness can be improved twice. In addition, since the number of cathodes can be tripled while ensuring the same brightness as in the related art, the display area of the gas discharge display panel can be increased. Indeed, in the second DC-driven gas discharge display panel 40, the number of cathodes belonging to each cathode group is increased as compared with the first DC-driven gas discharge display panel 10, because the number of cathodes is smaller. Although the scanning time per one cathode is shortened, the brightness is inferior, but there is an advantage that the configuration can be simplified.

いうまでもない。As described above, as the number of sections on the cathode side is increased, the scanning time per cathode is extended and the luminance is improved. On the other hand, the anode member has a multilayer structure, and the light generated in the discharge cells 32 is reduced accordingly. It is necessary to partially pass through many members before being radiated to the outside. Therefore, it is necessary to increase the overall transparency as much as possible by adjusting the materials and dimensions (thickness) of the front substrate 12, each anode member, and each transparent insulating film. Needless to say, by omitting either the fifth anode member 56 or the sixth anode member 58, the cathode 20 can be divided into five groups.
