Below with reference to Fig. 6 to Figure 16, the embodiment of plasma display module of the present invention is elaborated.
Fig. 6 is the PDP module of expression according to the present invention the 1st embodiment, and Fig. 7 is the sectional view of expression PDP modular structure shown in Figure 6; In addition, Fig. 8 is the synoptic diagram of the output signal path of expression Y-Z associating plate shown in Figure 7.
Fig. 6 and PDP module shown in Figure 7 are made of following several parts: PDP70; Be arranged on the heat shield panel 86 at the back side of PDP70; Be arranged on the Y-Z associating plate 100 at heat shield panel 86 back sides; And data-driven plate 80; Control panel 72; In addition, also comprise respectively power panel (indicating on the figure) to above-mentioned each plate 100,80,72 supply power.
92 one-tenth co-ordinative constructions of upper plate 90 and lower plate of PDP70, and leave gas discharge space.Here, scanning electrode wire (Y1 to Ym) and keep electrode wires (Z1 to Zm) and on upper plate 90, be arranged side by side (as shown in Figure 2).And data electrode wire (X1 to Xn) is positioned on the lower plate 92.In addition, be provided with Y buffer zone 94 in a side of upper plate 90, and the Y pad (not indicating on the figure) that links to each other with scanning electrode wire of formation; Be provided with Z buffer zone 96 in other side, and form and keep the Z pad (not having on the figure to indicate) that electrode wires (not having on the figure to indicate) links to each other.
And, be provided with X buffer zone (not indicating on the figure) in a side of upper plate 92, and the X pad that links to each other with data electrode wire of formation (on the figure less than indicating).Y buffer zone 94 on this upper plate 90 and the lower plate 92, Z buffer zone 96 and X buffer zone (not indicating on the figure) all are emerging in the outside.
For heat shield panel 86 can be distributed the heat that PDP70 produced at an easy rate to the outside, overlapping setting be carried out in heat shield panel 86 back sides complete and PDP70.
Data-driven plate 80 is used to supply with to the data electrode wire of PDP70 via X FPC88 then from the X of control panel 72 timing controling signal generation data pulse (DP) as shown in Figure 3.Here, X FPC88 be arranged on data-driven plate 80 and PDP70 and go up X buffer zone (figure on less than sign) and link to each other.
As shown in Figure 3, turntable driving plate 73 is used to be created in the scanning impulse (SP) of restarting pulse (RP) and supplying with in the addressing time period (APD) that reboot time section (APD) is supplied with to scanning electrode wire from the Y of control panel 72 timing controling signal.And turntable driving plate 73 is supplied with to the scanning electrode wire of PDP70 via YFPC82 and is restarted pulse (RP) and scanning impulse (SP).
Here, as shown in Figure 7, YFPC82 links to each other with the Y buffer zone 94 of turntable driving plate 73 and PDP70.
As shown in Figure 3, Y-Z retaining plate (sustainer board) 74 is used to be created in Y that the section of holding time (SPD) supplies with to scanning electrode wire from the Y of control panel 72 and Z timing controling signal and keeps pulse (SUSPy) and keep pulse (SUSPy) with Y and alternately keep pulse (SUSPz) to keeping the Z that electrode wires supplies with.And as shown in Figure 3, Y-Z retaining plate (sustainer board) 74 is created in reboot time section (RPD) and addressing time period (APD) to keeping the bias pulse (BP) that electrode wires is supplied with.For this reason, Y-Z retaining plate (sustainer board) 100 comprises following two loops: the Y that production Y keeps pulse (SUSPy) keeps loop (not indicating on the figure); The Z that generation bias pulse (BP) and Z keep pulse (SUSPz) keeps loop (not indicating on the figure).As shown in Figure 8, this Y-Z retaining plate (sustainer board) 74 is via connector 75-〉turntable driving plate 73-〉YFPC82 supplies with Y to the scanning electrode wire of PDP70 and keeps pulse (SUSPy).And as shown in Figure 8, Y-Z retaining plate (sustainer board) 74 keeps to PDP70 that electrode wires is supplied with bias pulse (BP) and Z keeps pulse (SUSPz) via ZFPC84.
Here, as shown in Figure 7, ZFPC84 is electrically connected with Y-Z retaining plate (sustainer board) 74, then via between PDP70 and the heat shield panel 868 be arranged on PDP70 on Z buffer zone 96 be connected.Constitute by metal material via the part between PDP70 and the heat shield panel 86 among this ZFPC84 with electric conductivity.
As mentioned above, YFPC82 links to each other with turntable driving plate 73, ZFPC84 by connector 104 with link to each other with Y-Z retaining plate (sustainer board) 74 that turntable driving plate 73 has a difference in height.Here, Y FPC82 is connected with the front (is benchmark with PDP70) or the back side of turntable driving plate 73.Z FPC82 is connected with the front or the back side of Y-Z retaining plate (sustainer board) 74.
For example, as shown in Figure 7 and Figure 8, Y FPC82 is connected with the back side of turntable driving plate 73, and Z FPC84 is connected with the front of Y-Z retaining plate (sustainer board) 74.Therefore, even one side Y FPC82 unites being connected of plate 100 with ZFPC84 with Y-Z, turntable driving plate 73 and Y-Z retaining plate (sustainer board) 74 is isolated by their difference in height, can prevent to come in contact each other.Therefore, can guarantee that driving is stable.In addition, Z FPC84 so that heat shield panel 86 can not be brought into play the effect of transmission current, thereby can be reduced to minimum degree via being connected with Z buffer zone 96 between PDP70 and the heat shield panel 86 with the electromagnetic interference (EMI) of PDP70.
But, as mentioned above, if the Z buffer zone 96 that wants to be arranged on the PDP70 according to the plasma display module of the present invention the 1st embodiment is connected by Y-Z retaining plate (sustainer board) 74, just must have via the Z FPC84 between PDP70 and the heat shield panel 86.This Z FPC84 is longer than connecting required length, so its work is just relatively more difficult, and this is its existing problem.Just developed PDP module as shown in Figure 9 in order to address this problem.
Fig. 9 is the PDP module diagram of expression according to the present invention the 2nd embodiment, and Figure 10 is the sectional view of expression PDP modular structure shown in Figure 9.
Fig. 9 and PDP module shown in Figure 10 are made of following components: PDP170; Be arranged on the heat shield panel 186 at the PDP170 back side; Be arranged on the Y-Z associating plate 200 at heat shield panel 186 back sides; Data-driven plate 180; Control panel 172; And respectively to the power panel of above-mentioned plate 200,180,172 supply powers (not indicating on the figure).
192 one-tenth co-ordinative constructions of upper plate 190 and lower plate of PDP170, and leave gas discharge space.Here, scanning electrode wire (Y1 to Ym) and keep electrode wires (Z1 to Zm) and on upper plate 190, be arranged side by side (as shown in Figure 2).And data electrode wire (X1 to Xn) is positioned on the lower plate 192.In addition, be provided with Y and Z buffer zone 194 in a side of upper plate 190, and the Y pad (not having on the figure to indicate) that is connected with scanning electrode wire of formation with keep the Z pad that electrode wires (not have sign figure on) is connected (on the figure less than sign).And, be provided with X buffer zone (not indicating on the figure) in a side of lower plate 192, and the X pad that is connected with data electrode wire of formation (on the figure less than indicating).Y on this upper plate 190 and the lower plate 192 and Z buffer zone 194 and X buffer zone (not indicating on the figure) all are emerging in the outside.
For heat shield panel 186 can be distributed the heat that PDP170 produced at an easy rate to the outside, overlapping setting be carried out in heat shield panel 186 back sides complete and PDP170.
Data-driven plate 180 is used to supply with to the data electrode wire of PDP170 via X FPC188 then from the X of control panel 172 timing controling signal generation data pulse (DP) as shown in Figure 3.Here, X FPC188 links to each other with X buffer zone (not indicating on the figure) on being arranged on data-driven plate 180 and PDP170.
As shown in Figure 3, turntable driving plate 173 is used to be created in the scanning impulse (SP) of restarting pulse (RP) and supplying with in the addressing time period (APD) that reboot time section (APD) is supplied with to scanning electrode wire from the Y of control panel 172 timing controling signal.And turntable driving plate 173 is supplied with to the scanning electrode wire of PDP170 via Y/Z FPC182 and is restarted pulse (RP) and scanning impulse (SP).
As shown in Figure 3, Y-Z retaining plate (sustainer board) 174 is used to be created in Y that the section of holding time (SPD) supplies with to scanning electrode wire from the Y of control panel 172 and Z timing controling signal and keeps pulse (SUSPy) and keep pulse (SUSPy) with Y and alternately keep pulse (SUSPz) to keeping the Z that electrode wires supplies with.And as shown in Figure 3, Y-Z retaining plate (sustainer board) 174 also is created in reboot time section (RPD) and addressing time period (APD) to keeping the bias pulse (BP) that electrode wires is supplied with.For this reason, Y-Z retaining plate (sustainer board) 200 comprises following two loops: the Y that production Y keeps pulse (SUSPy) keeps loop (not indicating on the figure); The Z that generation bias pulse (BP) and Z keep pulse (SUSPz) keeps loop (not indicating on the figure).This Y-Z retaining plate (sustainerboard) 174 is via connector 175-〉turntable driving plate 173-〉Y/Z FPC182 supplies with Y to the scanning electrode wire of PDP70 and keeps pulse (SUSPy).And Y-Z retaining plate (sustainer board) 174 is via connector 175-〉turntable driving plate 173-〉Y/Z FPC182 keeps to PDP70's that electrode wires is supplied with bias pulse (BP) and Z keeps pulse (SUSPz).
Here, as shown in figure 10, Y/Z FPC182 is electrically connected with Y-Z associating plate 200, and is connected with the Y/Z buffer zone 194 that is arranged on PDP170 one side.That is to say, as shown in figure 11, the Y pad 194a that links to each other with scanning electrode wire with keep the side that Z pad 194b that electrode wires links to each other is positioned at PDP170, and be connected, thereby can simply be connected with 200 realizations of Y-Z associating plate by a Y/Z FPC connector 82 with Y-Z associating plate 200.In view of the above, can carry out work more easily.At this moment, the side of PDP170 forms Y and Z pad 194a, 194b simultaneously.Therefore, as shown in figure 12, the pin number of the connection of Y/Z FPC182 increases twice than the Y FPC that is connected with original Y buffer zone.But as shown in figure 13, under the situation of YY-ZZ electrode structure, keeping electrode wires is common electrode wires.Therefore, two lines are merged, as shown in figure 14, just passable if the pin number that increases of being connected with Z pad 194b is half of scanning electrode wire.
On the other hand, as shown in figure 15, electrode structure shown in Figure 13 only from one side of PDP170 to scanning electrode wire with keep the electrode wires service voltage, the voltage that being caused by electrode impedance just appears in therefore opposite one side descends gradually, thereby causes the PDP170 both sides to produce luminance difference.That is to say that to scanning electrode wire with keep A point that electrode wires begins service voltage to scanning electrode wire with to keep the voltage that electrode wires supplies with big, so two electric discharge between electrodes frequently take place, thereby improve its brightness.But, more and more littler with the voltage of keeping the electrode wires supply at the B point to scanning electrode wire, so its brightness will reduce gradually.Afterwards, significantly reduce to scanning electrode wire and the voltage of keeping the electrode wires supply at the C point, a little less than two electric discharge between electrodes just become more and more.So the brightness of ordering at C significantly reduces.Therefore, difference appears in the both sides brightness of PDP170, and its comparative reduces.Just worked out electrode structure as shown in figure 16 for addressing these problems.
With reference to Figure 16 as can be seen, for improving the comparative of PDP170, keep formation black matrix (Black Matrix) 195 between the electrode wires at adjacent two that merge.At this moment, black matrix 195 can use the material with electric conductivity, as shown in figure 13, for keeping electrode wires supplying electric current (voltage) to adjacent two, forming pad Y and Z194a, the opposite location of 194b, the position that promptly forms original Z pad is kept black matrix 195 electrode wires and is connected with adjacent two.Therefore, as shown in figure 16, keep the electric currents (voltage) that electrode wires supplies with to adjacent two and form current delivery, keep the electrode wires supply that circulates to adjacent respectively by black matrix 195 then along dotted arrow symbol direction.Thus, though only from one side of PDP170 to scanning electrode wire with keep the electrode wires service voltage, also can make scanning electrode wire and keep the certain voltage difference of maintenance between the electrode wires, thereby can make PDP170 obtain uniform brightness.
In addition, as shown in figure 16, electrode structure shown in Figure 16 forms current delivery by black matrix 195 along dotted arrow symbol direction, and to keeping electrode wires supplying electric current (voltage).Therefore, the electric current of supplying with to scanning electrode wire (voltage) and opposite to the direction of keeping the electric current (voltage) that electrode wires supplies with, its magnitude of current is identical.So cancel out each other in magnetic field, thereby mutual electromagnetic interference (EMI) can be minimized.
