時点灯（放電発光）させるようにしている。 As is already well known, this kind of AC-driven gas discharge display panel, for example, has a pair of electrodes placed on both sides of a discharge gas space with a dielectric layer interposed therebetween, and an electric field is applied between the two electrodes to produce a discharge light. The display is characterized in that it exhibits a memory effect due to the effect of wall charges induced on the surface of the dielectric material during the discharge. On the other hand, since such panels generally exhibit discharge delay characteristics peculiar to gas discharge display elements, the initial write operation tends to be uncertain. The discharge cell is always lit (discharges light) as a pilot discharge cell (hereinafter referred to as a pilot cell).

な問題があつた。 However, because this pilot cell also lights up with a delay from when the device's power switch is turned on due to discharge delay characteristics, there is information input that needs to be written when the pilot cell is not lit. if you did this,
It is not possible to generate a discharge corresponding to the information. In other words, there was a big problem in that writing and displaying errors occurred.

より、オペレータの疲労の原因となつていた。 Therefore, in order to improve this conventional problem, the pilot flame voltage pulse (peak value) applied to the pilot flame cell is
The idea was to increase the voltage (150V to 180V) and turn it on instantly. However, with this method, the power source for the pilot flame becomes expensive, the dielectric surface corresponding to the pilot flame cell deteriorates due to high voltage, the discharge voltage of the cell concerned increases, and the spattered dielectric There has been a problem in that body wall surface components adhere to nearby display cells and induce characteristic fluctuations of the display cells. In addition to this, the generation of a powerful pilot discharge light caused operator fatigue.
いずれにしても、従来のパネル構造では、高品

特徴とするものである。 In view of the above-mentioned circumstances, this invention aims to provide a high-quality panel structure, and includes an auxiliary pilot cell that can be lit with commercial AC voltage near the pilot discharge cell. The present invention is characterized in that the pilot flame discharge cell is lit at the same time as the power switch is turned on by constantly discharging (lighting) the pilot flame cell.

An auxiliary pilot flame discharge cell (auxiliary pilot flame cell) is formed in the opposing gap between the electrodes 17, and a display discharge cell (display cell) is formed in each opposing gap between the display X electrode group 14 and the Y electrode group 18. .

are connected, and display drive circuits DXD and DYD are connected to the display X and Y electrode groups, respectively. Note that 19 is a fuse. The pilot flame drive circuit includes a pair of switching transistors Q 1 and Q 2 connected in series between the pilot flame voltage source VP and ground, as shown as a representative of the Y-side circuit PYD, and Its operation is such that a pilot voltage pulse is generated from the connection point P by alternately switching both transistors using a clock-like input signal (not shown). As mentioned above, this voltage pulse is 150V to 180V above the discharge start voltage level.
As a result of being applied to the main pilot cell through each main pilot electrode, a pilot discharge is generated in the cell.

ている。 On the other hand, as is well known, the voltage peak value of the commercial AC power supply PWS is 280V peak-to-peak.
This is lower than the peak value of 150 to 180V of the pilot voltage pulse mentioned above. Therefore, if the auxiliary pilot cell structure to be supplied is the same as the main pilot cell structure, discharge cannot be reliably generated. Therefore, in the present invention, the auxiliary X and Y pilot electrodes 13 and 17 that define the auxiliary pilot cell are set so that the ignition voltage of the auxiliary pilot cell is set lower than that of the main pilot cell and the cell is lit with commercial AC voltage.
The electrode area has been increased and the cell shape has been increased. As a method for reducing the ignition voltage, in addition to the electrode area expansion method described above, a method of forming a layer of material having a large secondary electron emission coefficient on the electrode is also known.

ことになる。 Thus, according to the auxiliary pilot cell configuration, the main pilot cell is always lit (discharged) by the commercial AC voltage regardless of the operation of the power switch of the device, and the pilot flame effect caused by the discharge causes the main pilot cell to instantly turn on. It will be lit.

わめて有利である。 As is clear from the above description, the gas discharge display panel of this invention is provided with an auxiliary pilot cell that can be lit by a commercial AC power source near the main pilot cell, and the main pilot cell is constantly discharged. Since the lighting of the pilot cell is encouraged, it is possible to provide a high-quality panel with no delay in lighting the pilot. In addition, since the power supply used is a relatively small voltage value, there is no risk of deteriorating the surface of the dielectric layer corresponding to the electrode, and it has the advantage of requiring little power consumption.Furthermore, the discharge light of the auxiliary pilot cell is weak (commercial AC (Because the voltage frequency is 50 or 60Hz), there is no adverse effect on the operator. Therefore, it would be extremely advantageous to apply this invention to a gas discharge display panel equipped with a pilot cell.
