Plasma display device

Technical field

TECHNICAL FIELD [0001] The present invention generally relates to a plasma display device, and more particularly to a wiring structure of discharge electrodes of a plasma display device.

Background art

[0002] Flat display devices using flat display panels have been put to practical use over a wide range, replacing conventional cathode-ray tubes with small display power and large displays. Especially in the field of large displays, plasma display panels have superior characteristics in terms of their principle structure, and are being commercialized as the mainstream.

FIG. 1 is a schematic cross-sectional view of a three-electrode surface discharge AC-plasma display panel.

[0004] A three-electrode surface discharge AC—plasma display panel is composed of two glass substrates, a front glass substrate 15 and a back glass substrate 11. The front glass substrate 15 has a BUS electrode as a sustain electrode. A common sustain electrode (X electrode) and a scanning electrode (Y electrode) composed of 17 and the transparent electrode 16 are formed. These X electrodes and Y electrodes are arranged alternately. A dielectric layer 18 is formed on the X and Y electrodes, and a protective film 19 such as MgO is formed on the dielectric layer 18.

[0005] The BUS electrode 17 has high conductivity and functions to supplement the conductivity of the transparent electrode 16. The dielectric layer 13 functions to maintain a discharge due to wall charges and has a low melting point glass force.

An address electrode 12 is formed on the rear glass substrate 11 so as to be orthogonal to the X electrode and the Y electrode. A dielectric layer 13 is formed on the address electrode 12, and a partition wall 14 is formed on the dielectric layer 13 at a position corresponding to the gap between the address electrodes 12.

[0007] Between the barrier ribs 14, phosphor layers R, G, and B are formed so as to cover the dielectric layer 13 and the barrier rib side walls. The phosphor layers R, G, and B correspond to three colors of red, green, and blue. When the plasma display panel is driven, ultraviolet rays are generated by the discharge between the X electrode and the Y electrode, and the phosphor layers R, G, and B are excited by the ultraviolet rays and emit light to display an image. [0008] A discharge gas such as a mixed gas of neon and xenon is filled between the front surface on which the X electrode and the Y electrode are provided and the back surface on which the address electrode 12 is provided. The space where the X electrode, the heel electrode, and the address electrode intersect constitute one discharge cell (pixel).

FIG. 2 is a block diagram showing the main part of the overall configuration of a conventional plasma display device. The plasma display device shown in FIG. 2 includes a plasma display panel 21, an address electrode drive circuit 22, an electrode drive circuit 23, an X electrode drive circuit 24, a scan circuit 25, a drive control circuit 26, and a signal processing circuit 27. .

[0010] The signal processing circuit 27 receives an externally input clock signal, display data, vertical synchronization signal, horizontal synchronization signal, etc., and writes display data of RG to the internal frame memory based on the vertical synchronization signal, etc. Do the work. The drive control circuit 26 controls the address electrode drive circuit 22, the negative electrode drive circuit 23, the X electrode drive circuit 24, and the scan circuit 25 to display the display data stored in the frame memory on the plasma display panel 21. .

Specifically, the drive control circuit 26 generates an address control signal corresponding to the display data of the frame memory in synchronization with the clock signal. The address control signal is supplied to the address electrode drive circuit 22. The drive control circuit 26 further generates a scan driver control signal for controlling the scan circuit 25 in synchronization with the vertical synchronization signal and the horizontal synchronization signal. The scan driver control signal is supplied to the scan circuit 25. The drive control circuit 26 further drives the heel electrode drive circuit 23 and the X electrode drive circuit 24 in synchronization with the vertical synchronization signal and the horizontal synchronization signal.

The address electrode drive circuit 22 applies an address voltage pulse corresponding to display data to each address electrode A1 to Am (corresponding to the address electrode 12 in FIG. 1) in synchronization with the clock signal. The Y electrode drive circuit 23 drives each of the Y electrodes Y1 to Yn independently via the scan circuit 25. The X electrode drive circuit 24 drives the even-numbered electrodes of the X electrodes XI to Χη in common, and independently drives the odd-numbered electrodes of the X electrodes XI to Χη.

[0013] By the operations of the address electrode drive circuit 22, the Υ electrode drive circuit 23, the X electrode drive circuit 24, and the scan circuit 25, each display pixel is initialized in the reset period and the next address is set. The pixel to be displayed is selected during the scan period, and the selected pixel is caused to emit light during the last sustain period.

In the reset period, the reset Z address voltage generation circuit in the Y electrode drive circuit 23 generates a reset voltage, and the scan circuit 25 applies the reset voltage to all the Y electrodes Y1 to Yn. The reset voltage generated by the reset / address voltage generator in the X electrode drive circuit 24 is applied to all the X electrodes XI to Xn.

[0015] In the address period, the scan circuit 25 drives the address electrodes while sequentially driving the Y electrodes Y1 to Yn one by one by the address voltage generated by the reset Z address voltage generation circuit of the Y electrode drive circuit 23. The circuit 22 applies address voltage pulses corresponding to the lines of each horizontal line corresponding to the display data to the address electrodes A1 to Am in parallel. This selects the cell to be displayed and controls the display / non-display (selection Z non-selection) of each display cell (pixel).

[0016] During the sustain period, the sustain voltage noise generated by the sustain noise circuit in the Y electrode drive circuit 23 is applied to the Y electrodes Y1 to Yn via the scan circuit 25, and the X electrode drive circuit 24 The sustain voltage pulse generated by the sustain pulse circuit is applied to the X electrodes XI to Xn. By applying a sustain voltage pulse, a sustain discharge is generated between the X electrode and the Y electrode in the cell selected as the display cell.

When the sustain discharge is generated, as described above, the X-electrode drive circuit 24 drives the X-th electrode evenly from the X-electrodes XI to Xn, and independently from the X-electrodes XI to Xn. Are driven in common. From this, the ALIS (Alternate Lighting of Surfaces) type electrode is driven. The ALIS method uses all electrode gaps as display lines for low cost and high definition. In the plasma display panel 21, all display lines between the X electrodes XI to Xn and the Y electrodes Y1 to Yn, that is, between Y1 and XI, between XI and Y2, between Y2 and X2, and between X2 and Y3 It is not possible to turn on all the display lines in between. Therefore, one frame is divided into two fields, odd lines (for example, between Y1 and XI, between Y2 and X2) are displayed in the first field, and even lines (for example, XI and Y2) are displayed in the second field. Between X2 and Y3). In order to realize such a display, a sustain electrode drive circuit used in the ALIS method is used. Are configured so that different voltages can be applied to the odd-numbered X electrodes XI, X3,... And the even-numbered X electrodes Χ2, Χ4,.

FIG. 3 is a diagram showing a conventional example of the configuration of a portion where an X electrode is taken out from the plasma display panel 21. In FIG. 3, the same components as those in FIGS. 1 and 2 are referred to by the same numerals, and a description thereof will be omitted.

On the glass substrate 15 of the plasma display panel 21, odd-numbered X electrodes X—odd and even-numbered X electrodes X—even are provided. In order to electrically connect these X electrodes to the X electrode drive circuit 24, a two-layer flexible cable 31 is used. Two-layer flexible cable 31 has a wiring pattern 32 on the first layer and a wiring pattern 33 on the second layer.

The wiring pattern 32 is connected to the odd-numbered X electrode X_odd. All these connected X electrodes X—odd are grouped together in the two-layer flexible cable 31 and electrically connected to each other. The wiring pattern 33 is connected to the even-numbered X electrode X_even. All of these connected even-numbered X electrodes X—even are connected together in a two-layer flexible cable 31 and electrically connected to each other.

[0021] Generally, the wiring pattern 32 of one two-layer flexible cable 31 is not connected to all X electrodes X—odd provided on the plasma display panel 21. Only connected. Similarly, the wiring pattern 33 is not connected to all the X electrodes X—even provided on the plasma display panel 21 but only to some X electrodes X—even. This is because when a two-layer flexible cable 31 that can be connected to all X electrodes is manufactured, its size is the same as the vertical length of the plasma display panel 21, and such a two-layer flexible cable with such a large size is used. This is because the cable 31 is expensive. Therefore, in general, a small number of two-layer flexible cables 31 are connected to one plasma display panel 21, and the X electrode X—odd is divided into several groups, one layer for each group. The structure is summarized in flexible cable 31.

However, regardless of its size, a multilayer flexible cable such as the two-layer flexible cable 31 is more expensive than a single-layer flexible cable. Therefore, the two-layer frame There is a problem that the use of a large amount of the kibble cable 31 leads to an increase in the cost of the plasma display device.

BEST MODE FOR CARRYING OUT THE INVENTION

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The main part of the overall configuration of the plasma display device of the present invention is the same as that shown in FIG. 2, and the internal configuration of the plasma display panel 21 is the same as that shown in FIG. However, the configuration of the X electrode extraction part from the plasma display panel 21 is different from the conventional one.

FIG. 4 is a view showing a first embodiment of a configuration of a portion for taking out an X electrode from the plasma display panel 21 according to the present invention. In FIG. 4, the same components as those in FIGS. 1 and 2 are referred to by the same numerals, and a description thereof will be omitted.

[0031] On the glass substrate 15 of the plasma display panel 21, odd-numbered X electrodes X—odd and even-numbered X electrodes X—even are provided! /. The odd-numbered X electrodes X—odd are connected to each other and connected together for common driving, and are connected to one common electrode 51. The even-numbered X electrodes X—even are connected to each other for common driving, and are combined into one, and are connected to one common electrode 52. For convenience of explanation here, it is assumed that the common electrode 51 and the common electrode 52 are the last part of the wiring to be drawn out from the plasma display panel 21 in order to connect the X electrode from the plasma display panel 21 to the X electrode driving circuit 24. To do.

The odd-numbered X electrode X_odd is connected to one common electrode 52 provided on the glass substrate via a wiring pattern 44 provided on the glass substrate 15. The even-numbered X electrode X—even is connected to the common electrode 51 via a conductor cable having an insulation coating (in this example, the connection wiring 45 of the single-layer flexible cable 41). At this time, the conductor cable (connection wiring 45 of the single-layer flexible cable 41) is arranged so as to cross over the wiring pattern 44 existing on the glass substrate 15. More specifically, the even-numbered X electrode X—even is connected to the wiring pattern 43 provided on the glass substrate 15 via the single-layer flexible cable 41, and further on the glass substrate 15 via the wiring pattern 43. Connected to the common electrode 51 The

Here, even-numbered X electrodes X—even connected to the common electrode 51 may be all even-numbered X electrodes X—even provided in the plasma display panel 21. The odd-numbered X electrodes X—odd connected to the common electrode 52 may be all of the odd-numbered X electrodes X—odd provided in the plasma display panel 21. In this case, the single-layer flexible cable 42 that connects all X electrodes of the plasma display panel 21 to the X electrode drive circuit 24 is a flexible cable that also has two connection wiring forces connected to the common electrode 51 and the common electrode 52, respectively. But ...

In the above description, it is assumed that the even-numbered X electrode X—even is connected to the single-layer flexible cable 41. On the contrary, the odd-numbered X electrode X—odd is connected to the single-layer flexible cable 41. It is good also as a structure connected to. In this case, the even-numbered X electrode X—even is connected to one common electrode by the wiring pattern provided on the glass substrate 15.

As described above, in the configuration shown in FIG. 4, one of the plurality of even-numbered X electrodes X—even and the plurality of odd-numbered X electrodes X—odd is provided on the glass substrate. The wiring electrode is connected to one common electrode provided on the glass substrate, and the other plurality of electrodes are connected to one other common electrode via a conductor cable having an insulation coating. At that time, the conductor cable is arranged so as to cross over the wiring pattern existing on the glass substrate. By adopting such a configuration, it is not necessary to use a two-layer flexible cable as in the conventional case, and the cost can be reduced. Further, since the size of the single layer flexible cable 41 can be made smaller than that of the conventional two layer flexible cable 31 shown in FIG. 3, the cost can be further reduced. In addition, since the electrodes are already shared in the wiring lead-out portion from the plasma display panel 21, the size of the connector portion that couples the plasma display panel 21 and the single-layer flexible cable 42 can be reduced. Cost can be reduced.

FIGS. 5 to 7 are views for explaining further effects of the configuration of the X electrode lead-out portion according to the present invention shown in FIG. FIG. 5 is a diagram showing an example of the arrangement of components such as circuit boards when a conventional plasma display device is viewed from the back. In FIG. The same components as those in FIG. 2 and FIG. 3 are referred to by the same numerals, and a description thereof will be omitted.

[0037] The plasma display device shown in FIG. 5 includes a plasma display panel 21, a two-layer flexible cable 31, a power supply circuit board 61, a signal processing circuit board 62, a Y drive circuit board 63, an X drive circuit board 64, and a scan driver. Board 65, address relay board 67, X relay board 68, and flexible cable 69 are included.

[0038] The power supply circuit board 61 is equipped with a power supply circuit that supplies power to each circuit portion. The signal processing circuit board 62 is mounted with the signal processing circuit 27 of FIG. The Y drive circuit board 63 carries the Y electrode drive circuit 23 of FIG. The X drive circuit board 64 is equipped with the X electrode drive circuit 24 of FIG. The scan driver board 65 includes the scan circuit 25 shown in FIG. The scan circuit 25 of the scan driver board 65 is connected to a Y electrode disposed on the front surface of the plasma display panel 21 via a flexible cable 69. Further, the X electrode drive circuit 24 of the X drive circuit board 64 is connected to the X electrode disposed on the front surface of the plasma display panel 21 via the X relay board 68 and the plurality of two-layer flexible cables 31.

[0039] As described above, generally, a plurality of small-sized two-layer flexible cables 31 are connected to one plasma display panel 21, and the X electrode X—odd is divided into several groups. Each group is composed of one two-layer flexible cable 31. In this case, since the vertical size of the X drive circuit board 64 is smaller than the vertical size of the plasma display panel 21, the X relay is used to connect a plurality of two-layer flexible cables 31 to the X drive circuit board 64. A substrate 68 is required. Providing such an X relay board 68 leads to an increase in cost.

FIG. 6 is a diagram showing another example of the arrangement of components such as circuit boards when a conventional plasma display device is viewed from the back. In FIG. 6, the same elements as those of FIG. 5 are referred to by the same numerals, and a description thereof will be omitted.

In the configuration shown in FIG. 6, two X relay boards 68 are provided, and the X drive circuit board 64 is connected to the two-layer flexible cables 31 via these two X relay boards 68. It has been continued. Other configurations are the same as those shown in FIG. Even in the configuration of FIG. 6, the provision of the X relay board 68 leads to an increase in cost. FIG. 7 is a diagram showing an example of the arrangement of components such as each circuit board when the back surface force of the plasma display device according to the present invention is viewed. In FIG. 7, the same elements as those of FIG. 5 are referred to by the same numerals, and a description thereof will be omitted.

The arrangement example of the components shown in FIG. 7 corresponds to the configuration shown in FIG. 4, and the X electrode drive circuit 24 of the X drive circuit board 64 is connected to the plasma display via one single-layer flexible cable 42. Connected to the X electrode on the front of the panel 21. This single-layer flexible cable 42 is a flexible cable that connects all the X electrodes of the plasma display panel 21 to the X electrode drive circuit 24. The common electrode 51 and the common electrode 52 shown in FIG. The connection wiring power of

[0044] In the configuration shown in Fig. 4, the cost of working on the flexible cable can be reduced compared to the conventional configuration shown in Fig. 3, so all even-numbered X electrodes X-even are combined into one. All the odd-numbered X electrodes X—odd are combined into one, and the electrodes can be pulled out by one single-layer flexible cable 42. In such a configuration, as shown in FIG. 7, the single-layer flexible cable 42 without using the X relay board can be directly connected to the X drive circuit board 64. Therefore, the cost can be further reduced as compared with the case where the X relay board 68 is required as in the configurations of FIGS.

FIG. 8 is a diagram showing a second embodiment of the configuration of the portion for taking out the X electrode from the plasma display panel 21 according to the present invention. In FIG. 8, the same components as those of FIG. 4 are referred to by the same numerals, and a description thereof will be omitted.

In the configuration of FIG. 8, all X electrodes on the plasma display panel 21 are grouped, and one common electrode 51 and one common electrode 52 are provided for each group. Similarly, one wiring pattern 43 and one wiring pattern 44 are provided for each group. The force that a plurality of connection wirings 45 are also provided for each group The single-layer flexible cable 41 may be composed of one flexible board as a whole. The configuration of the connection between the even-numbered X electrode X—even and the common electrode 51 and the configuration of the connection between the odd-numbered X electrode X—odd and the common electrode 52 are the same as those shown in FIG. It is.

In the configuration of FIG. 8, one common electrode 51 is not connected to all even-numbered X electrodes X even provided on the plasma display panel 21, but is a part of even-numbered X-electrodes. Only connected to electrode X—even. This is because when the conductor widths of the common electrode 51 and the wiring pattern 43 are the same, the number of even-numbered X electrodes X—even is compared to a configuration in which all even-numbered X electrodes X—even are combined into one. These groups can be divided into these groups and combined into one group for each group. This is a force that can reduce the influence of impedance on the common electrode 51 and wiring pattern 43 in the part where the electrodes are combined. . The same applies to the common electrode 52 and the wiring pattern 44 provided for the odd-numbered X electrodes X-o dd.

In FIG. 9, the same components as those in FIG. 4 or FIG. 8 are referred to by the same numerals, and a description thereof will be omitted. In FIG. 9, the illustration of the glass substrate 15 is omitted.

In the configuration of FIG. 9, the common electrode 51 is widened to be the common electrode 51 A, and the common electrode 52 is widened to provide the common electrode 52 A. Similarly, all or a part of the wiring width of the wiring pattern 43 and the wiring pattern 44 is increased to provide the wiring pattern 43A and the wiring pattern 44A, respectively. With such a configuration, it is possible to reduce the impedance of the common electrode and the wiring pattern and realize efficient X electrode driving. The wide portions of the common electrodes 51A and 52A and the wiring patterns 43A and 44A may be configured as mesh electrodes, respectively.

In the configuration shown in FIG. 9, the entire configuration is such that all even-numbered X electrodes X—even are connected to one common electrode and all odd-numbered X electrodes X—as shown in FIG. The odd number may be connected to one common electrode. Alternatively, as shown in FIG. 8, even-numbered X electrodes X—even and odd-numbered X electrodes X—odd may be divided into a plurality of groups and grouped into one common electrode for each group. Good.

FIG. 10 is a diagram showing a fourth embodiment of the configuration of the portion for taking out the X electrode from the plasma display panel 21 according to the present invention. In FIG. 10, the same elements as those of FIG. 4 or FIG. 8 are referred to by the same numerals, and a description thereof will be omitted. In FIG. 10, the illustration of the glass substrate 15 is omitted.

In the configuration of FIG. 10, a single-layer flexible cable 41 A is provided instead of the single-layer flexible cable 41. As part of the single layer flexible cable 41A The wiring pattern 43 is included, and even-numbered X electrodes X—even are combined into one by a single-layer flexible cable 41A, and then connected to one common electrode 51 provided on the glass substrate. Thus, the wiring pattern 43 is not formed on the glass substrate 15 but may be formed inside the single-layer flexible cable.

In the configurations shown in FIGS. 4, 8, and 9, there are portions that need to be aligned between the single-layer flexible cable 41 and the electrodes on the glass substrate on both sides of the single-layer flexible cable 41. FIG. On the other hand, in the case of the configuration shown in FIG. 10, the single layer flexible cable 41A and the electrode on the glass substrate need only be aligned on one side of the single layer flexible cable 41A. Therefore, an effect that the alignment operation is easy can be obtained.

FIG. 11 is a diagram for explaining the relationship between the single-layer flexible cable 41 and the wiring on the glass substrate. In FIG. 11, the same elements as those of FIG. 9 are referred to by the same numerals, and a description thereof will be omitted. The illustration of the glass substrate 15 is omitted.

In the configuration shown in FIG. 11, even-numbered X electrodes X—even and odd-numbered X electrodes X—odd are formed on the glass substrate! Between even-numbered X electrode X—even and odd-numbered X electrode X—odd, even-numbered Y electrode Y—even or odd-numbered Y electrode Y—odd is formed on the glass substrate, The

[0056] The odd-numbered X electrodes X—odd are connected to the wiring pattern 44A formed on the glass substrate. The even-numbered X electrode X—even is connected to one end of the connection wiring 45 of the single-layer flexible cable 41.

The other end of the connection wiring 45 of the single-layer flexible cable 41 is connected to the wiring pattern 43A. The odd-numbered X electrode X odd (see Fig. 1) is directly below the connection wiring 45 of the single-layer flexible cable 41. A wiring pattern 44A to be connected to 1) is formed on the glass substrate 15. That is, the single-layer flexible cable 41 is arranged on the wiring pattern 44A formed on the glass substrate 15 so as to cover and cover the wiring pattern 44A.

[0059] In the configuration described above, the connection wiring 45 of the single-layer flexible cable 41 is covered with insulation, so that the connection wiring 45 and the wiring pattern 44A are not electrically connected. If the wiring pattern 44A and the connection wiring 45 are insulated from each other in this way, the single-layer flexible cable 41 should be used if the connection wiring 45 can be crossed over the wiring pattern 44A. Is not necessarily required. That is, for example, a plurality of conductor cables are connected to a plurality of even-numbered X electrodes X-even by using individual conductor cables that are individually insulated and coated as connection wiring 45, and these conductor cables are connected to each other. It may be configured to cross over the wiring pattern 44A. However, there is an advantage that the force assembly using the single layer flexible cable 41 is much easier.
