 In FIG. 5, white circles indicate discharge cells.

FIG. 6 is an explanatory view of a scanning signal applied to the cathode, and FIG.
Figure is an explanatory view of the timing of the discharge light emission in the discharge cells, in Figure 7 shows the Oyobi data signal, for example A ₁ of the signal waveform scan signal, for example C ₁ of the signal waveform.

As shown in FIG. 7, the scanning signal includes an ON signal for forming light emission of the discharge cell, for example, a voltage signal of 0 V, and an OFF signal for extinguishing light emission of the discharge cell, for example, a voltage of the cathode pre-bias voltage V _Cpb 80 V. The ON state (for example, the state of 0 V) continues only for a time T. A pulse signal of a pulse is applied to the cathode 20 as one unit of ON.

Similarly, as shown in FIG. 7, the data signal also includes an ON signal, for example, a voltage signal of 180 V, and an OFF signal, for example, a voltage signal of the anode pre-bias voltage V _Apb 100 V, and is ON only for a time T (for example, a state of 180 V). ) Is applied to the anode 12 as one unit of ON signal.

In displaying characters and figures by the light emission of the discharge cells, one unit of the ON signal is generated by the cathodes 201, 202,.
n, so that these cathodes are sequentially turned on (see FIG. 6). And the anodes 121, 122, ...
In order to perform display by selectively causing the discharge cells to emit light, an ON or OFF signal (data signal) is applied to each of the 12 m at the same time as the cathode is turned on.
A voltage equal to or higher than the discharge starting voltage (for example, 130 V) is applied to the discharge cells to emit light by applying an ON signal to both the anode and the cathode. In addition, a voltage less than the discharge starting voltage is applied to the discharge cells that do not want to emit light by applying an off signal to the anode and / or the cathode.

For example, as shown in FIG. 7, the period s ₁ In ~s ₂ cathode 201
An ON scan signal is applied to the cathodes 202 to 20n, and an OFF data signal is applied to the anodes 121 and an ON data signal is applied to the anodes 121.
Therefore, in this case, discharge light emission is formed in the discharge cells in the intersection region between the cathode 201 and the anode 121, and the cathodes 202 to 20n and the anode 121
No discharge light emission is formed in the discharge cells in the intersection region with the above.

OFF data signal is applied to the period s ₂ ~s ₃ and s ₅ ~s ₆ At the anode 121, thus intersecting also the anode 121 and the cathode 201~20n as on the scanning signal is applied to this case cathode 201~20n No discharge light emission is formed in the discharge cells in the region.

Period on the data signal to the anode 121 along with the off scan signal is applied to s ₃ ~s ₄ in the cathode 201 is applied, and therefore the discharge light emission is not formed in the discharge cells intersections of this case cathode 201 and anode 121 The discharge light emission is formed in the discharge cells in the intersection area between the anode 121 and the cathode 121 to which the on-scan signal is applied among the cathodes 202 to 20n.

If it is not desired to emit light from the discharge cells in the intersection region between the anode 121 and the cathodes 201 to 20n, it can be understood from the above description that an off-data signal may be applied to the anode 121. When the ON data signal is applied, crosstalk (erroneous discharge) occurs between the anode 122 and one of the cathodes 201 to 20n facing the anodes 121 and 123 to which the ON scanning signal is applied. In order to prevent the occurrence of such crosstalk, the partition walls 18 are provided between adjacent anodes so as to protrude to such a height that erroneous discharge can be prevented.

(Problems to be Solved by the Invention) In gas discharge light emission, a wavelength band suitable for the wavelength sensitivity characteristics of various photoconductors can be selected according to the composition of a sealing gas. For example, application to an optical head of an electrophotographic printer (optical printer) has been considered. Hereinafter, the structure of the gas discharge type optical head will be briefly described with reference to the drawings.

FIG. 8 is a diagram showing an example of the structure of the gas discharge type optical head focusing on the wiring structure.

In the illustrated gas discharge type optical head, a plurality of anodes (261, 262,..., 261) are arranged in a line in the main scanning direction on one substrate (not shown), and a plurality of anodes are arranged on the other substrate (not shown). Cathode (2811, 2822, ..., 2818, 2821, ..., 2828, ...
.., 2811,..., 2818) are arranged in parallel, and the one and the other substrates are bonded to each other so that the anode and the cathode are orthogonal to each other, and a discharge gas is sealed between these substrates.

One anode is used as a common electrode for any suitable number of cathodes (for example, eight), and one anode and any suitable number of cathodes (for example, anode 261 and cathodes 2811, 2812,.
818) constitute one unit of electrode block, and a plurality of electrode blocks are arranged along the main scanning direction to form one block line.

Further, a plurality of scanning electrodes (for example, eight scanning electrodes 301, 302,..., 308) are provided on the other substrate so that cathodes selected so as not to overlap from each electrode block are commonly connected. , And the scanning electrodes are connected, for example, the cathodes 2811, 2821,..., 2811 are commonly connected by the scanning electrode 301, and a matrix connection by multilayer wiring is performed.

Data signals A ₁ , A ₂ ,..., A ₁ are connected to the anodes 261, 262,.
, 308 receive scanning signals C ₁ , C ₂ ,..., C ₈ , respectively.

Even in the gas discharge type optical head having the above-described configuration, in order to form discharge light for optical writing, a data signal and a scanning signal are input in the same manner as in a conventional DC-PDP, and thus the scanning electrodes 301, 302, and One unit of the ON signal is applied to 303,... A partition 32 is provided between adjacent electrode blocks (between adjacent anodes) to prevent crosstalk.

However, in a display device (display), the pixel density may be about 3 dots / mm, but in an optical head, it is desired to increase the pixel density to about 8 dots / mm to 16 dots / mm. In order to satisfy such a demand for higher definition, it is necessary to reduce the distance between adjacent electrodes. The partition is formed by, for example, a thick film printing technique, but the partition is formed in a narrow space between the electrodes as described above.
It is very difficult to project the projections to a height that can prevent erroneous discharge and to position them with high precision. Therefore, the yield is poor and the cost is high. On the other hand, if no partition is formed, crosstalk occurs.

The purpose of this generation is to solve the above-mentioned problems, and to prevent the occurrence of crosstalk between adjacent electrode blocks without providing a partition wall between adjacent electrode blocks in one row of block lines. Is provided.

(Means for Solving the Problems) In order to achieve this object, in the driving method of the gas discharge light emitting device according to the present invention, one unit of the electrode block is opposed to one anode in association with the anode. A plurality of electrode blocks arranged in a line, at least one row of block lines formed by arranging a plurality of electrode blocks, and a gas discharge luminescence having a dischargeable gas interposed between the anode and the cathode. In driving the apparatus, one cathode constituting one electrode block and the other cathode constituting the other electrode block adjacent to the one electrode block, and scanning of the adjacent one and other cathodes are performed. , One different from the other cathode after the one cathode
After scanning one or a plurality of cathodes, the other cathode is scanned.

(Operation) According to the driving method as described above, one cathode constituting one electrode block and the other cathode constituting the other electrode block adjacent to the one electrode block,
In scanning the adjacent one and the other cathodes, the one and the other cathodes are not sequentially scanned. Therefore, the ON signal is not sequentially applied to the adjacent one and the other cathodes, so that it is possible to prevent crosstalk between the electrode blocks adjacent in the line direction of the block line.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. It should be noted that the drawings are only schematically shown to the extent that the present invention can be understood, and thus the dimensions, shapes, arrangement relations, and numerical conditions of the respective components are not limited to the illustrated examples.

In this embodiment, an example in which the present invention is applied to a gas discharge type optical head will be described.

First, an example of the structure of a gas discharge type optical head suitable for applying the driving method of the present invention will be described with reference to FIG. 2 and FIG.

FIG. 2 is a perspective view of an essential part schematically showing an example of the structure of a gas discharge type optical head, and FIG. 3 is a view partially showing a wiring structure of the optical head shown in FIG. In FIG. 2, in order to facilitate the understanding of the drawing, the hidden line of the scanning electrode is represented by a dashed line, the auxiliary discharge cathode, the hidden line of the auxiliary discharge anode and the cathode is represented by a two-dot chain line, and the hidden lines of other components are represented by dotted lines. The hidden lines are partially omitted. Further, in FIG. 3, the discharge cells formed in the corresponding areas opposed to the anode and the cathode are indicated by white circles.

As shown in the figure, in the illustrated optical head, a plurality of transparent anodes 42 (421, 422,...) Made of, for example, ITO are main-scanned on a front substrate 40 made of a transparent material such as glass. The auxiliary discharge cathode 52 is provided to extend in the arrangement direction of the anodes 42, and further, a plurality of auxiliary discharge anodes 54,
The anode 54 is provided so that one end of the anode 54 faces the auxiliary discharge cathode 52 and is spaced at a predetermined interval in the arrangement direction of the anodes 42. Reference numeral 56 denotes a current limiting resistor connected in series to the anode 42, 58 denotes an auxiliary discharge current limiting resistor connected in series to the auxiliary discharge anode 54, and 60 denotes a power supply for auxiliary discharge.

In addition, a plurality of cathodes 46 (4611, 4612,
, 4618, 4621, ..., 4628, 4631, ..., 4641, ...) are arranged in parallel along the main scanning direction.

A block (for example, 42) including one anode 42 and any suitable number of cathodes 42 opposed to each other in association with the anode 42
A block including one and eight cathodes 4611 to 4618) is one unit of an electrode block B, and a plurality of electrode blocks B are arranged in a line along the main scanning direction to form a single block line. I have. Associated anode 42 and cathode
Predetermined discharge cells for optical writing are formed in a region facing 46, and thus a plurality of discharge cells for writing are arranged in a line in the main scanning direction.

There is a statistical discharge start delay (discharge start delay time) from when the on-voltage signal is applied to the anode 42 and the cathode 46 to when the discharge starts between the anode 42 and the cathode 46. Therefore, an auxiliary discharge is always performed between the auxiliary anode 54 and the auxiliary cathode 52 to supply ions, excited atoms, and the like to the discharge cell for optical writing, thereby suppressing a systematic delay in starting the discharge (seeker effect).

Further, on the back substrate 44, an arbitrary suitable number of scanning electrodes 48 (for example, scanning electrodes 481 to 484 on one side and scanning electrodes 485 to 488 on the other side) are arranged on one side and the other side of the cathode 46. The cathodes 42 are alternately extended to one side and the other side, and are connected to the corresponding scanning electrodes 48.

As shown in FIG. 3, the cathodes 46 constituting one unit of the electrode block B are electrically connected to different scanning electrodes 48, respectively. The cathode 42 and the scanning electrode 48 are connected in a matrix by multilayer wiring, for example, the scanning electrode 481 and the cathode 461.
, 46n1, the scan electrode 482 and the cathodes 4612, 462
, 46n2, and the same connection as shown in FIG. 8 is performed. Data signals A ₁ , A ₂ ,..., _An are supplied to anodes 421, 422,..., 42n via resistors R, respectively, and scanning signals C ₁ , C are applied to scanning electrodes 481, 482,. ₂ ,..., C ₈ are supplied.

Further, on the back substrate 40, a light emission control layer 50 made of, for example, a dielectric paste is provided to cover one side and the other side of the cathode 46 so as to expose a portion of the cathode 46 facing the anode 42.

Then, the outer peripheral portion of the substrate 40 is sealed to the substrate 44 by a security sealing portion (not shown) via a spacer (not shown) for keeping the separation distance between the substrates 40 and 44 constant.
Anodes 42 and 54 and cathodes 46 and 52 and a discharge gas medium, for example, a mixed gas of Ne and Ar, which are sealed so as not to leak outside, are enclosed between 40 and 44.

Next, an embodiment of the present invention will be described with reference to FIGS.

Figure 1 is a time chart for explaining an embodiment of the present invention, an example of a waveform of the data signal (e.g., data signals A ₁₎ and the scanning signal C ₁ -C _8.

As shown in FIG. 1, in this embodiment, the data signal comprises an ON signal, for example, a voltage signal of 180 V, and an OFF signal, for example, a voltage signal of an anode pre-bias voltage V _Apb 100 V,
ON state only during time T (for example, 180V voltage applied state)
Is applied to the anode 42 as one unit of ON signal.

The scanning signal includes an ON signal, for example, a voltage signal of 0 V, and an OFF signal, for example, a voltage signal of a cathode pre-bias voltage V _{Cpb of} 80 V, and is a pulse of one pulse in which an ON state (for example, a 0 V voltage applied state) continues only for a time T. The pulse signal is applied to the cathode 46 as one unit of the ON signal.

As can be understood from FIG. 3, during the period when the ON signal is applied to the scan electrode 481, the cathodes 4611, 4621, and 463 are used.
, 46n1, and the cathodes 4612, 4622, 4632,..., 46 during the period in which the ON signal is applied to the scan electrode 482 and the ON signal is applied to the scan electrode 482.
During the period when the ON signal is applied to n2 and the ON signal is applied to the scan electrode in the same manner, the cathode ON signal corresponding to the scan electrode is applied.

In a predetermined discharge cell for optical writing, light emission is formed when an ON signal is applied to both the anode 42 and the cathode 46, and when an OFF signal is applied to one or both of the anode 42 and the cathode 46. An extinction state is formed.

In the wiring structure as shown in FIG. 3, one cathode constituting one electrode block and the other cathode constituting the other electrode block adjacent to one electrode block, one cathode and the other adjacent to each other The cathode (hereinafter, simply referred to as the adjacent one and the other cathode) is the rightmost cathode of one electrode block and the leftmost cathode of the other electrode block in the adjacent one and other electrode blocks. Refers to, for example, cathodes 4618 and 4621, and cathodes 4628 and 4631
Are adjacent one and the other cathodes.

The scanning of the adjacent one and the other cathodes is performed by scanning an arbitrary suitable number (one or more) of the cathodes different from the other cathode following the one cathode and then scanning the other cathode. In this embodiment, the scanning order of the cathodes 46 does not matter, but in this embodiment, as shown in FIG. 1, the scanning electrodes 481, 482, 483, 484, 488, 487, 486, 4
The scanning of each cathode 46 is performed by applying an ON signal in time sequence in the order of 85, and such scanning is repeated. At this time, the ON signal is applied to any one of the scan electrodes 481 to 488, and the OFF signal is applied to the remaining scan electrodes.For example, during the period when the ON signal is applied to the scan electrode 481, An off signal is applied to the remaining scan electrodes 482 to 488.

As a result, in the adjacent one and the other cathodes, the one and the other cathodes are not sequentially scanned, that is, the ON signal is not sequentially applied to the adjacent one and the other cathodes. Therefore, it is possible to prevent crosstalk between adjacent electrode blocks in the line direction of the block lines (main scanning direction).

Hereinafter, the principle of the occurrence and prevention of crosstalk will be described with reference to a more specific example.

In gas discharge, charged particles and ions are generated by the discharge and after the discharge is stopped, the charged particles etc. gradually decrease,
In the state where many charged particles remain, discharge is very likely to occur. Accordingly, between the anode of the discharge cell where the discharge is formed and the cathode adjacent to the cathode of the discharge cell where the discharge is formed (for example, between the anode 421 and the cathode 4621, between the anode 422 and the cathode 46).
18, the discharge is very likely to occur between the anode 422 and the cathode 4631), which may cause crosstalk.

Here following the next discharge light emission of the discharge cells L ₁₈ between the anode 421 and the cathode 4618 as an example, consider the case of forming the discharge light emission in the discharge cells L ₁₁ between the anode 421 and the cathode 4611.

Scan electrodes 481, 482, 483, 484, 485, 48 as before
On signals are sequentially applied in the order of 6, 487, and on signals are repeatedly applied to the scanning electrodes 481 to 488 in this order, and the respective cathodes 4611 to 46 are applied.
When n8 is to be scanned, an ON signal is applied to the anode 421 during a period during which the ON signal is applied to the scan electrode 488, and then an ON signal is applied to the anode 421 during a period during which the ON signal is applied to the scan electrode 481. sequentially discharge light emission in the cells L ₁₈ and cell L ₁₁ is formed.

Incidentally, the period for forming the discharge light emission in the cells L ₁₁ is the on-signal to the scan electrodes 481 is applied is turned on the signal also is applied to the cathode 4621, thus each ON signals simultaneously to the anode 421 and the cathode 4261 is applied State.

Moreover, while later the discharge light emission is stopped in the cell L ₁₈ so that like many charged particles remain in the vicinity of the cell L _18, a cathode 4621 is adjacent to the cathode 4618 of the anode 421 and the cell L ₁₈ cells L ₁₈ In this state, discharge light emission is very easily formed. Note that discharge light emission is very easily formed between the anode 421 and the cathode 4617.

When the discharge light emission is easily formed, the anode
As a result of the ON signals being applied to the 421 and the cathode 4621, there is a possibility that discharge light emission, that is, crosstalk, occurs between the electrodes 421 and 4621.

This crosstalk occurs because an ON signal is sequentially applied to one and the other cathodes adjacent to each other (for example, cathodes 4618 and 4621). Therefore, the adjacent one and the other cathodes are sequentially turned on. By scanning each of the cathodes 4611 to 46n8 so that no signal is applied, the occurrence of the crosstalk as described above can be prevented.

As shown in FIG. 1, in this embodiment, the scanning electrodes 48 are provided.
1, 482, 483, 484, 488, 487, 486, and 485 are sequentially applied to the ON signal in order to scan each cathode 46, so that the ON signal is sequentially applied to one and the other adjacent cathodes. Never be.

Consider the case of forming a sequentially discharge light emission in the cells L ₁₈ and L ₁₁ as an example. As in this embodiment shown in Figure 1, it is applied an ON signal to the scanning electrodes 488 in a period of time s ₁ ~s _2, sequentially to the scan electrodes 487,486,485 for a period of time s ₂ ~s ₃ in the After applying an oN signal, when applied an oN signal to the scanning electrodes 481 in a period of time s ₃ ~s _4, thus focusing on the phases adjacent one and other cathode 4618 and 4621, one of the cathode
After scanning the cathode different from the other cathode 4621 following 4618,
The other cathode 4621 is scanned, and these adjacent cathodes 4618 and
4621 is not scanned sequentially.

Thus even if a discharge light emission during a period of time s ₁ ~s ₂ in cell L _18, charged particles period the charged particles or the like of the time s ₂ ~s ₃ remains in cell L ₁₈ near Yuki gradually decreases and the like Since the state becomes very small or substantially disappeared, the time s ₃ to
It is applied respectively on signal to the anode 421 and the scan electrodes 481 for forming the discharge light emission of cells L ₁₁ in the period s _4, the anode 4
Crosstalk between the cathode 21 and the cathode 4621 can be substantially eliminated.

Similarly, the occurrence of crosstalk is substantially reduced also for anodes and cathodes other than the anode 421 and the cathode 4621 that may cause crosstalk, such as the anode 421 and the cathode 4621, the anode 422 and the cathode 4618, and the anode 422 and the cathode 4631. Therefore, the occurrence of crosstalk between adjacent electrode blocks can be prevented.

In this embodiment, the scanning order of each cathode 4611 to 46n8 is
The scanning of the adjacent one and the other cathodes may be performed in any scanning order as long as one cathode is scanned next to the other cathode and then the other cathode is scanned. In addition to the examples described above, for example, the scanning electrode 48
4, 483, 482, 481, 485, 486, 487, and 488 are sequentially applied to the ON signal, and the ON signal is repeatedly applied to the scanning electrodes 481 to 488 in this order to scan the cathodes 4611 to 46n8. You may do it.

The present invention is not limited to the above-described embodiment, and accordingly, the wiring structure, signal waveforms, application timings of each signal, numerical conditions, and the like for realizing the driving method of the present invention can be appropriately selected. Can be changed.

The driving method of the present invention can be applied to gas discharge light emitting devices having various structures other than the optical head having the above-described structure, and can be applied to gas discharge light emitting devices having two or more rows of discharge cells.

For example, by arranging a plurality of cathodes along the main scanning direction,
A row of cathode groups is formed, and the cathode groups are arranged along the sub-scanning direction by two.
A row of rows constitutes a first row and a second row of cathode groups, the anode extends in the sub-scanning direction, is disposed opposite to the cathodes of both the first row and the second row, and one cathode and A gas having a structure in which one unit of an electrode block is constituted by any suitable number of cathodes in both groups of the first row and the second row, and a plurality of electrode blocks are arranged along the main scanning direction to form a row of block lines. It can be applied to a discharge type optical head.

(Effects of the Invention) As is clear from the above description, according to the driving method of the gas discharge light emitting device of the present invention, gas discharge light emission having at least one block line in which a plurality of electrode blocks are arranged in a line shape. In driving the device, one cathode constituting one electrode block and the other cathode constituting the other electrode block adjacent to the one electrode block, and scanning of one adjacent cathode and the other cathode are performed. The scanning is performed so that the one cathode is scanned next to a cathode different from the other cathode, and then the other cathode is scanned.

As a result, the adjacent one and the other cathodes are not sequentially scanned, so that the ON signal is not sequentially applied to the adjacent one and the other cathodes, so that the partition wall is formed between the adjacent electrode blocks in the line direction of the block line. Even without this, crosstalk between adjacent electrode blocks can be prevented.

Therefore, it is not necessary to provide a partition wall between adjacent electrode blocks to prevent crosstalk, so that the production cost of the gas discharge light emitting device can be reduced.
