The signal generator 1 is a signal that changes with time in accordance with the instructions of the computer 7. The degree (frequency) of electricity over time is, for example, A Page 12 \\ 312 \ 2d-code \ 90-03 \ 90100952.ptd 494232 V. Description of the invention (10) 50 0 kHz to 10 MHz is should. In addition, the generated signal is either rectangular wave-shaped DC or AC. In addition, the signal generator is independent of the instructions of the computer 7, and it is also possible for the signal generator to occur frequently. The signal processor 2 is a filter processing that removes noise, etc. from the voltage appearing in the electrode group, [00 or 10], and a process that amplifies the voltage potential. The oscilloscope 3 measures the voltage potential from the signal sent from the signal processor 2. The measurement result is sent to the computer 6. The probe 4 is individually assigned to each electrode of the electrode group 丨 〇〇 and 〇〇1,-each of the = 4 means that one end is in contact with one end of each electrode ', and the other end is connected to the multi-transformer: 5, 5.

At this time, the electrode 100a is buried in the electrode 101. The electrostatic capacity is correspondingly provided: the phase at the portion where the m electrode iou intersects vertically—two π /, ,, and a voltage appearing at the electrode 1 0 a. 2 _ Management "^ is processed by the pin 4 and the multiplexer 5, processed by the signal processor z, and measured by the oscilloscope 3. The brain 6 determines whether the voltage measured by the oscilloscope 3 is at a predetermined level If it is within the predetermined range, it is determined that the electrode 1 〇1 a is not disconnected, and if it is within the pre-set range, it is determined that the electrode 丨 〇 丨 a is disconnected. It is determined that the electrode 1 0 1 a is not disconnected. When disconnected, move to other electrodes and perform inspection. Θ Here, the so-called “predetermined range” is to use the false panel B to perform pre-disconnected electrodes and non-disconnected electrodes in the same order. The range determined by the obtained data: Generally speaking, when the electrode to be inspected is disconnected, the level of the above-mentioned voltage obtained from the electrode perpendicular to it will decrease. Therefore, it is measured in advance that the disconnection does not occur. The voltage level when the line is disconnected and the voltage level when the disconnection occurs, and the value between these voltage levels is used as the lower limit for determining the disconnection. ^ As described above, the inspection device A is' will cross perpendicularly to the inspection object.

494232 V. Description of the invention (12) Secondly, when the electrode 101a is disconnected, the method described by Jingyou is as follows. j ^ 疋 忒 Position First, based on the results of the above inspection, 'know that there is a disconnection relationship between electrode 10a (probe 4 side) and electrode 100a, 1 00 & while the electrode is connected to the signal processing, then it is determined whether the voltage appearing at the electrode 100b is within a predetermined range. If it is within a predetermined range, the electrode 10a is not disconnected from one end of the electrode 10a to the electrode 100b. Therefore, it occurs between the electrode 100 and the electrode 10 Ob. Disconnector. If it is not within the predetermined range, it can be considered that from the end of the electrode i0ia to the electrode 100b, t # 1〇la has a disconnection relationship. Use a multiplexer 5 instead of the electrode i00b to connect the electrode 100c is connected to the signal processor 2. Hereinafter, the result of the same method is repeated to find the part where the electrode 丨 〇 丨 a is broken. For example, when a disconnection occurs at point X in FIG. 1, the voltage appearing on the electrode will change with the boundary between the electrode 100b and the electrode 100c as the boundary. As a result of performing the above method on all the electrodes of the electrode groups 100 and 101, the disconnection inspection of the plate surface B can be completed. The relationship between the line and the line can also be repaired. The above-mentioned inspection method is "on", and even the voltage appearing at 100a away from the electrode 1 0 1 a. This is because of the relationship between broken lines in almost all parts. 丨 When checking the method, you can understand the break. When the electrode 1 0 a is disconnected, the electrode at the furthest end of the initial end (probe 4 side) is inspected with one inspection. However, for example,

494232 V. Description of the invention (13) When the place is limited to a certain part, etc., the voltage appearing at 1 0 0 c is also acceptable. At this time, σ, · ^ is not the one farthest from the electrode end to the electrode 100C can be inspected from the electrode 1 Ola. The above inspection method is to supply the probe 4 and the voltage that changes with time to Y The position of the end pin 4 on one of the electrodes 101a is not limited to this, and may be θla, however, it may be supplied by touching any part. Live, contact the electrode 101a, and the above inspection method is to select an electrode 1 0 1 a that is not an electrode 1 0 1 a perpendicular to the parent from the inspection group ^ ^ ^ ^ ^ ^ ^ ^ ^ The voltage of 〇a is determined in accordance with a predetermined range. == Two-electrode is now = select a plurality of electrodes from the electrode group 10 °, compared to the result of the voltage appearing in the special car compared with each other, if Electrode = = = = The relationship will be different depending on the voltage. For example, there is a break at point X in Figure 1. The voltage appearing at electrode 10a and electrode 10 () b is slightly the same. It appears at other electrodes, such as the same voltage as electrode 100c. Flat. "Yi" means that you can use this method to win the day. The advantage is that you can save the work and time of measuring the "predetermined ^" mentioned above, and you can know whether the electrode is disconnected and you can specify the disconnection location. ^^ At this time, the measurement and the electrode of inspection (electrode 丨 〇 丨 a) are perpendicular to each other, and the voltage appearing in all the electrodes of the pole group (electrode group 100) is also acceptable. The range of the line and only the eight electrodes of the electrode group that intersects vertically may be measured by leaf. In the electrode group of the vertically intersecting electrode group 1 90100952.ptd page 16 494232 5. In the description of the invention (14), skip one method or two methods, and it is also possible to measure the electrodes at appropriate intervals.

It is characterized by including one of the aforementioned electrodes, which provides two electrodes with time. Any one of the selected electrodes and any of the electricity * = Measured by the number of the hard electrode which measuring means; and ,,,. Regarding the voltage appearing in the result of the electric house, whether the electricity according to the foregoing measurement is not within a predetermined range, and judge whether the above-mentioned 90100952.ptd page 25 494232 VI. The electrode selected for the scope of patent application is, A mechanism for judging whether or not a disconnection occurs in a portion between the aforementioned electrodes for measuring the voltage by the aforementioned measuring mechanism. 2 2. An inspection device for a plasma display panel, which is an inspection device for inspecting the disconnection of a plurality of electrodes of the plasma display panel, and is characterized by including: selecting any one of the foregoing electrodes A mechanism for supplying a voltage that changes with time to the selected electrode; a measuring mechanism for measuring the voltage appearing as a result of supplying the voltage to each of the plurality of the electrodes perpendicularly crossing the selected electrode; and comparing each other Based on the results of the measured voltages, the selected electrode is a judging mechanism for determining whether a disconnection has occurred. \\ 312 \ 2d-code \ 90-03 \ 90100952.ptd Page 26
