Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-electrode AC memory type plasma display, and more particularly, to a method for driving a color plasma display which can be operated stably with a wide operating margin and suitable for high luminance and high definition of the device. .

[0002]

2. Description of the Related Art A plasma display is expected as a display device capable of realizing a large wall-mounted TV as one of the flat display devices. In the plasma display, a discharge cell corresponding to a display pixel is selectively discharged, and a fluorescent material is excited by emitting ultraviolet light to obtain three primary colors of red, green, and blue, thereby realizing color display.

[0003] The plasma display includes:
DC type plasma display with electrodes exposed to discharge space, and AC type (AC type) with electrodes isolated from discharge space
There is a plasma display. As described above, the AC type plasma display is generally known to have a long life because the electrodes are isolated from the discharge space.

[0004] This AC type plasma display also includes a facing type plasma display in which electrodes are opposed to each other and a surface discharge type plasma display in which electrodes are arranged in parallel on the same substrate. Among them, the surface discharge type plasma display has a wide memory margin and is suitable for large-screen display.

[0005] Among the surface discharge type plasma displays, a three-electrode AC memory type plasma display comprising a pair of parallel surface discharge electrodes and a data electrode orthogonal thereto is a large color display having a long life and high efficiency. It is considered to be the most suitable plasma display.

FIG. 4 schematically shows a cross section of an example of a conventional configuration of a three-electrode AC memory type plasma display having a memory function. As a conventional three-electrode AC memory type plasma display having this configuration, for example, the description in Japanese Patent Application Laid-Open No. 4-332430 is referred to.

Referring to FIG. 4, a conventional three-electrode AC memory type plasma display comprises a first insulating transparent substrate 1, a second
Insulating substrate 2, scan electrode 3, sustain electrode 4, data electrode 5,
It is composed of insulating layers 6, 7, a protective layer 8, a phosphor 9, and a partition (not shown). Note that reference numeral 11 denotes a discharge space, and reference numeral 12 denotes a pixel. In FIG. 4, stripe-shaped partitions (not shown) are orthogonal to the scanning electrodes 3 and the sustaining electrodes 4 so as to separate pixels and secure a gap between the first insulating substrate 1 and the second insulating substrate 2. Is formed.

The conventional three-electrode AC memory type plasma display will be described in more detail. The first insulating substrate 1 and the second insulating substrate 2 use soda glass plates. First
On the insulating substrate 1, a transparent scanning electrode 3 and a transparent sustain electrode 4 are formed of a Nesa film or ITO (I
(Nindium Tin Oxide) film. The electrodes are formed by a general formation method such as a chemical vapor deposition method for a nesa film and a sputtering method for an ITO film.

The scan electrode 3 and the sustain electrode 4 are covered with an insulating layer 6. The insulating layer 6 is formed by kneading a low-melting-point lead glass powder together with an organic binder, forming a paste, printing and firing. Here, the insulating layer 6
The first insulating substrate 1 is formed of a transparent layer, and the insulating layer 7 is formed of the second insulating substrate 2 with a white reflective layer mixed with titanium oxide or the like, and emits light from the first insulating substrate 1 side. It has a structure that can be taken out efficiently.

The data electrode 5 is formed by printing and baking silver paste in a stripe shape or printing and baking it in a solid shape and patterning it by photolithography.

The protective layer 8 is formed by evaporating magnesium oxide so as to cover the insulating layer 6 on the first insulating substrate 1.

The phosphor 9 is formed by using a thick film printing technique.
Red, green, and blue phosphor pastes are applied in stripes along the partition walls, and then fired.

This plasma display has a scanning electrode 3
A write discharge is generated only in the pixel which emits light according to the display data between the scan electrode 3 and the data electrode 5, and the wall charges are formed on the insulating layer 6 on the scan electrode 3 side. The desired light emission is obtained by maintaining the discharge between the electrodes 4. The display is performed by selectively exciting the red, green, and blue phosphors 9 to emit light with vacuum ultraviolet light generated by the sustain discharge 4.

FIG. 7 is a block diagram showing a driving apparatus for the conventional AC discharge memory type AC plasma display shown in FIG. Referring to FIG. 7, the driving device includes a plasma display panel 13, a data driver 14, a sustaining driver 15, a scanning driver 16, a scanning pulse generating circuit 17,
Interface circuit 18, data power supply 19, sustain power supply 2
0, a scanning power supply 21, and a priming power supply 22.

Display data and control signals from outside the device are appropriately converted by an interface circuit 18 and supplied to a data driver 14, a sustain driver 15, and a scanning driver 16. The pre-discharge pulse, scan pulse, and sustain pulse B applied to the scan electrode 3 are generated by a scan pulse generator 17, and the timing of the scan driver 16 is controlled by a signal of an interface circuit 18.

Similarly, the pre-discharge pulse and the sustain pulse A applied to the sustain electrode 4 are generated under the control of the interface circuit 18 by the sustain driver 15.

Pre-discharge pulse, sustain discharge pulse A, B
Is applied to the scan electrode 3 and the sustain electrode 4 in common, so that the driver is composed of a discrete circuit using an FET having a high breakdown voltage, a large power, and a low on-resistance.

On the other hand, since the scanning pulse needs to be applied to each scanning electrode 3 at different timings, the number of circuits is required by the number of the scanning electrodes 3. Therefore, the high withstand voltage I
C is applied to the scanning electrode 3 in a superimposed manner by a diode.

Since a data pulse also needs to be independently applied to each data electrode 5 in accordance with display data, a high voltage IC is used as the data driver 14. Here, the high breakdown voltage IC is used because each of the scanning electrode 3 and the data electrode 5 is driven independently, so that a large number of circuits are required and the output current is relatively small. This is possible because the cost of the driving circuit can be reduced.

The driving method of this plasma display is as follows.
This will be described with reference to FIGS.

The driving method shown in FIG. 5 is called a subfield method. FIG. 5 shows an example in which 256 gradations are displayed using eight subfields. Images that switch at a rate of one per 1/60 second (1
Field) divided into eight subfields SF1 to SF
It is a method of expressing by superimposition of 8. Subfield SF
Since each of 1 to SF8 is different in display brightness by 2 ⁿ , desired luminance can be obtained by an appropriate combination.

In this method, each subfield is divided into a preliminary discharge (priming) period, a write discharge period, and a sustain discharge period.

In the pre-discharge period, the scan electrode 3 and the sustain electrode
Applying a preliminary discharge pulse between and causes a discharge discharge,
In addition to generating charged particles such as electrons in the discharge space, the wall charges on the electrodes in the pixels are controlled to a constant amount, thereby stabilizing the discharge during the writing period.

During the write discharge period, as described above, all the scan electrodes 3 are sequentially scanned by applying a scan pulse for each subfield, and the data pulse applied between the scan electrode 3 and the data electrode 5 in accordance with display data. As a result, a writing discharge is generated, and display data is written on the scanning electrode 3 as wall charges.

During the sustain discharge period, the scan electrodes 3 are applied to the scan electrodes 3 in accordance with the written wall charges, as shown in FIGS.
A sustain pulse B shown in (d) is applied.
In addition, there is a function of applying the sustain pulse A shown in FIG. 6A to generate a discharge and maintaining the discharge to realize a desired display.

[0026]

According to the conventional driving method described above, the display capacity is increased in the same display area, and in particular, the number of scanning electrodes (corresponding to the number of pixels in the vertical direction) is increased.
In order to realize high-definition display, in the plasma display having the above-described structure, the gap between the pixels becomes small, the discharge coupling between the pixels is strengthened, and the diffusion and movement of the charged particles from the adjacent pixels are originally required. In this case, non-selected pixels are erroneously turned on.

In order to increase the brightness of the plasma display having the above-described structure by the above-described conventional driving method, if the electrode width of the scanning electrode 3 and the sustaining electrode 4 is increased, the distance between the pixels is increased as described above. The gap becomes smaller, the discharge coupling between the pixels is strengthened, and the originally unselected pixels may erroneously discharge and emit light due to diffusion or movement of charged particles from adjacent pixels. The occurrence of this erroneous lighting has squeezed the operation margin, and has hindered high definition and high luminance.

As a method for solving this problem,
There is also a method of surrounding the pixel with a partition to cut off the coupling of discharge between pixels, but in this case, the partition structure becomes complicated,
Not suitable for high-definition plasma displays,
In addition, there are problems that the exhaust conductance of the discharge space becomes small and it is difficult to manufacture the inside of the discharge space as a clean vacuum vessel.

Although the present invention is different from the present invention in purpose and configuration, a method for driving a color plasma display is disclosed in, for example, JP-A-6-43829, in which the number of addresses is reduced and the extra time is used. Then, increase the number of subfields, increase the number of gradations, perform more line scans, enable driving of a large screen panel, increase the number of sustain discharges, increase the brightness, and increase the number of driving cycles to achieve stable In order to provide a driving method for performing an operation, an address period in which writing of display data in the entire screen is performed by forming wall charges necessary for sustain discharge in accordance with the display data, and a sustaining period for light emission. The plasma display is driven by separating the sustain discharge period in which the discharge is repeated and the sustain discharge according to the display data during the sustain discharge period, and the And sequential driving for the wall charges formed in response to the display data in the scan period, methods to be driven by the interlace every line has been proposed. That is, in this driving method, the number of addresses (writing discharge of display data) is reduced, and the remaining time is used to increase the number of gradations, increase the screen size, and increase the luminance by using the extra time.
The frame is divided into a first frame and a second frame, and the frame is driven by skipping every one line (one scanning line).

Also, Japanese Patent Application Laid-Open No. Hei 7-191627 has an object to provide a driving method for reducing a difference in characteristics of a writing discharge and a sustaining discharge of a plasma display panel for each scanning line to reduce an operation margin. As
A scan electrode group including a first number of scan electrodes; a write discharge period for display selection in a time-division manner for each scan electrode; a sustain discharge period for sustain discharge according to display selection of the write discharge period; In a driving method of a plasma display panel having a pre-discharge period positioned,
A continuous pre-discharge pulse and a pre-discharge erase pulse are continuously applied to all the scan electrodes at the same time, and a first sustain discharge period is provided after the end of the write discharge period for each scan electrode obtained by dividing the first number into N. A driving method has been proposed in which a second sustain discharge period common to all scan electrode groups is provided after the end of the first sustain discharge period of the scan electrode groups. This driving method divides the plasma display into a plurality of scanning blocks to stabilize the writing operation of the plasma display, and performs a preliminary discharge, a writing discharge, and a sustaining discharge by blocking the sequence. This is to shorten the period from the preliminary discharge to the completion of the write discharge.

Accordingly, the present invention has been made in view of the above circumstances, and an object of the present invention is to avoid erroneous lighting which has hindered high definition and high brightness of a plasma display. It is an object of the present invention to provide a driving method of a color plasma display which can achieve high speed.

[0032]

In order to achieve the above object, the present invention comprises a plurality of scan electrodes corresponding to a scan line of a display discharge pixel and a plurality of sustain electrodes for maintaining a discharge of the display discharge pixel. An electrode pair, and a data electrode group consisting of a plurality of data electrodes for supplying display data orthogonal to the scan electrode group and the sustain electrode group. The scan electrode group, the sustain electrode group, and the data electrode A writing discharge period configured to fill a discharge pixel formed with a group with a gas and selectively generating a write discharge between the plurality of data electrodes while sequentially scanning the plurality of scan electrodes; And a sustain discharge period for maintaining a discharge written by the write discharge. Characterized by scanning closer than time exceeding one scan time scan time of the electrode.

In the present invention, one of the odd-numbered or even-numbered scanning electrodes is sequentially scanned at least one scanning time apart, and the scanning of the other scanning electrode is performed at an odd multiple of 5 scanning times or more. It is characterized in that it is delayed by a scanning time or more.

According to the present invention, an electrode pair is formed by a plurality of scan electrodes corresponding to a scan line of a display discharge pixel and a plurality of sustain electrodes for maintaining discharge of the display discharge pixel, and the scan electrode group and the sustain electrode are formed. A data electrode group comprising a plurality of data electrodes for supplying display data orthogonal to the group,
It is configured by filling a discharge pixel formed by the scan electrode group and the sustain electrode group and the data electrode group with a gas,
A write discharge period for selectively generating a write discharge between a plurality of data electrodes while sequentially scanning the plurality of scan electrodes, and a sustain discharge period for maintaining a discharge written by the write discharge, In the plasma display driving method, the scanning time of the adjacent scanning electrodes is separated by a time exceeding one scanning time, and the odd-numbered or even-numbered one of the scanning electrodes is scanned, and then the other is scanned. Of the one scan electrode, a preliminary discharge is generated only in a pixel corresponding to an odd (even) scan electrode, and a write discharge is generated by scanning the odd (even) scan electrode. Thereafter, sustain discharge is generated at least once only in the odd-numbered (even-numbered) pixels, and at the same time, preliminary discharge is performed only in the pixels corresponding to the even-numbered (odd-numbered) scanning electrodes. After generating, to generate a write discharge by scanning the scan electrodes of the even-numbered (odd),
Subsequently, the sustain discharge is generated once or more only in the even-numbered (odd-numbered) pixels to write the display data of all the pixels, and the even-numbered and odd-numbered pixels are simultaneously generated in the sustain discharge according to the written data. , Characterized in that.

The present invention has been made in view of the fact that, in a plasma display having a conventional structure, the occurrence of erroneous lighting which hinders higher definition and higher brightness is caused by coupling between pixels. It is another object of the present invention to provide a method which is different from the means for disconnecting the pixels by the partition structure, and which avoids the drawbacks of the method using the partition structure.

According to the present invention, the above-described display discharge is achieved by using a driving method of a color plasma display in which the above-mentioned scan electrodes are scanned and the write discharge generated during the write discharge period is not continuously performed in adjacent pixels. The connection between pixels could be broken. As a result, erroneous lighting can be prevented, and high definition and high luminance of the plasma display can be realized without using a structure in which the periphery of the pixel is surrounded by the partition walls to suppress the coupling of discharge between the pixels.

[0037]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 3 shows a block diagram of a driving unit of the plasma display according to the embodiment of the present invention. In FIG. 3, elements having the same functions as the elements shown in FIG. 7 are denoted by the same reference numerals.

Referring to FIG. 3, an embodiment of the present invention is as follows.
The difference from the configuration of the conventional driving unit shown in FIG. 7 is that the scanning driver 16 is divided into two systems 16 a and 16 b corresponding to odd-numbered and even-numbered scanning electrodes. Is provided with a memory 23 to have a function of rearranging display data.

That is, in the embodiment of the present invention, (S1), (S2), (S3), (S
4) and (S5), a driving method in which the scanning order of the scanning pulse is replaced is adopted. Therefore, the order of the data pulse is changed to the scanning electrode as shown in FIG. , 2, 3, 3 corresponding to the conventional scanning order of
..., n to 1, n-2, 3, n, 5, 2, 7, 4, ...
Is converted to the order. Here, n is the number of scanning electrodes.

This circuit change does not involve a change in the number of circuits, withstand voltage, etc. of the high-voltage driver circuit, and only a change in the logic circuit section is sufficient. For this reason, with a slight increase in equipment cost, higher brightness,
High definition can be realized.

Embodiments of the present invention will be described below based on specific examples. FIG. 1 shows a timing chart of the first embodiment of the present invention. FIG. 1 shows a preliminary discharge period, a write discharge period, and a sustain discharge period of a subfield.

In the first embodiment of the present invention, the application timing of the scan pulse and the data pulse applied to the scan electrode 3 and the data electrode 5 is different from that of the conventional driving method.
That is, the scan pulse applied to the odd-numbered scan electrodes S1, S3, S5,... Is applied every other scan time (the same as the state of the odd-numbered electrodes when all the scan electrodes are sequentially scanned). In this state, all the even-numbered scan electrodes are scanned with a delay of 4 scan times (five scan times from the immediately preceding odd-numbered scan pulse).

When scanning is performed by this method, the number of scanning electrodes becomes 48
If there are no scanning electrodes, scanning electrodes S1, S478, S3,
The scanning is performed in the order of 80, S5, S2, S7, S4,.
As another scan, S1, pause, S3, pause,
S5, S2, ..., S479, S476, pause, S47
8. Scanning is performed in the order of pause, S480.

However, according to this scanning order, the time required for scanning becomes longer only during the idle period. The data pulse order is converted and applied in a one-to-one correspondence with the scanning order to obtain a display.

With the above driving method, adjacent pixels are not continuously scanned. For this reason, due to the dispersion and movement of the charged particles generated by the writing discharge, the charged particles that have moved to the adjacent pixels are attenuated by recombination and the like, and an erroneous writing discharge does not occur, which has been a problem in the conventional method. Erroneous lighting of an adjacent pixel can be prevented.

As described above, a driving circuit that realizes a scanning method in which adjacent pixels are not continuously scanned needs to store display data in a memory and rearrange the data in correspondence with the scanning order.

In the first embodiment, since the data is delayed by 5 scans, the circuit cost can be reduced by using a line buffer.

Next, a second embodiment of the present invention will be described. In this method, first, the odd-numbered scan electrodes S1, S1
, S5,..., And then the even-numbered scan electrodes S
2, S4, S6,... In principle, it is the same as the first embodiment, and the same effect can be obtained.

Further, according to the present embodiment, the following effects are recognized because half of all the display data is written every other line, and then the data is written so as to fill the space between the written data.

On the other hand, according to the conventional method, the priming particles generated by the preliminary discharge are attenuated with time due to recombination or the like. Further, the charged particles formed by the write discharge attenuate with time from the end of the write discharge to the sustain discharge period. For this reason, when the display capacity is increased for higher definition, the time from the preliminary discharge to the write discharge, and further from the write discharge to the sustain discharge becomes longer, and the preliminary discharge is reduced due to the decay of the priming particles and charged particles. It has been known that the occurrence of a write discharge that is temporally separated from the source becomes unstable, and that the write discharge does not easily shift to a sustain discharge, which hinders the speeding up and stabilization of the write operation for higher definition. .

The second embodiment of the present invention is different from the above-described first embodiment only in the scanning method for writing data. Only the odd-numbered scanning electrodes are written for the entire screen first. Therefore, half the writing of the entire screen is completed in half the time of the conventional driving method from the preliminary discharge. Therefore, the writing operation of the odd-numbered pixels is completed more stably than the conventional driving method. Subsequently, the even-numbered pixels are written. The writing operation of the even-numbered pixels may be partially unstable compared to the conventional case, but the entire operation is not changed. For this reason, from the viewpoint of the reproducibility of the entire screen, a stable writing operation every other line is secured.
Visually (in terms of image quality), improvements in stability and high speed were observed as compared with the conventional driving method.

As a third embodiment of the present invention, an example in which the write operation stability of the second embodiment is further improved is shown in FIG.
This will be described with reference to FIG. In FIG. 2, the number of scanning electrodes is 48.
Taking the case of zero as an example, one of the subfields is shown.

In this embodiment, as in the second embodiment, first, odd-numbered scan electrodes are scanned, and then, even-numbered scan electrodes are scanned. The feature of the present embodiment is that first, a preliminary discharge is generated only in the odd-numbered pixels, and then scanning of the odd-numbered scan electrodes S1, S3, S5,... A first sustain period is provided in which sustain discharge is caused only once or more, and wall charges are formed on the scan electrodes 3 and the sustain electrodes 4 of the odd-numbered pixels.

At the same time, preliminary discharge occurs only in the even-numbered pixels. Thereafter, the even-numbered scan electrodes S2, S
4, S6,..., S480 are completed, and similarly,
A first maintenance period is provided.

As described above, after writing data to all of the odd-numbered and even-numbered scanning electrodes, a sustain discharge is generated to display.

According to this method, the time from the preliminary discharge to the write discharge of the even-numbered pixels is the same as that of the odd-numbered pixels, and the write operation is stabilized.

Further, since wall charges are surely formed on the scanning electrode and the sustain electrode in the first sustain period, the writing stability can be improved for the entire pixel and the speed can be increased.

In the conventional driving method, one scanning time is 2 to 4
Although the scanning was limited to about 500 lines in μS, according to the present embodiment, one scanning time can be reduced to about 1 to 2 μS, which is about a half, and scanning of about 1,000 lines can be performed.

As described above, the present invention is not limited to the above-described embodiments, but includes various forms and modifications according to the principle of the present invention, which are combinations that avoid continuous scanning of adjacent pixels. Of course.

[0060]

As described above, in the plasma display of the present invention, it is possible to prevent the above-mentioned scanning electrodes from being scanned and causing the writing discharge generated in the writing discharge period to be continuously generated in adjacent pixels in time. As a result, the coupling between the display discharge pixels can be cut off. As a result, even if a special structure is not adopted, false lighting which has hindered high definition and high brightness of the plasma display can be avoided. Has the effect of being able to Further, according to the present invention, it is possible to realize a high speed, for example, a scan time of 1
2 μS is possible, which enables scanning of about 1000 lines, which is twice the conventional method.

Moreover, the method for driving a color plasma display according to the present invention requires little change in the high-voltage circuit portion of the conventional driving circuit, thereby suppressing an increase in price.
