From the result, as Fig. 5 a, plasma display system of the present invention has reduced the on-off element of composition data drive integrated circult than the existing plasma display system of Fig. 3.Promptly, the on-off element that constitutes existing data-driven integrated circuit is as shown in Figure 3, with Top switch (Qt1, Qt2 is Qt3) with Bottom switch (Qb1, Qb2, Qb3) constitute, and the present invention is shown in Fig. 5 a, and the on-off element of composition data drive integrated circult has only driving voltage that switch 500 is provided, one of Q.
Here, the driving voltage of described Fig. 5 a provides switch 500, Q be with existing Fig. 3 in Top switch in the on-off element of composition data drive integrated circult (Qt3) same on-off element is good for Qt1, Qt2.In other words, the data-driven integrated circuit of the plasma display system of the present invention shown in Fig. 5 a can be described as and omit Bottom switch (Qb1, Qb2, structure Qb3) in the data-driven integrated circuit of the existing plasma display system shown in Fig. 3.
In the present invention, described driving voltage provides switch 500, the magnitude of voltage that Q was loaded with is to provide gauge tap 501 by data voltage, the data voltage that S1 provided (Va) and provide gauge tap 502 by bias voltage, the bias voltage that S2 provided (Vb) poor.Be loaded with on the data-driven integrated circuit of the present invention such as the little voltage of data voltage that is loaded with on the existing drive integrated circult shown in Figure 3.
As above give an account of and continue, plasma of the present invention shows the on-off element quantity that can reduce the composition data drive integrated circult, and reduces the voltage that data-driven integrated circuit was loaded with, and reduces the manufacturing cost of plasma display system.
In addition, provide gauge tap 501 at Fig. 5 a at data voltage, bias voltage provides gauge tap 502, and ground voltage provides and only connects the situation that a driving voltage provides switch 500 on the gauge tap 503.But these data voltages provide gauge tap 501, and bias voltage provides gauge tap 502, and ground voltage provides and can connect a plurality of driving voltages on the gauge tap 503 switch 500 is provided.Concrete as Fig. 5 b.
The explanation of repetition is omitted as Fig. 5 a in statement earlier in Fig. 5 b explanation.
As Fig. 5 b, difference and described Fig. 5 a, data voltage provides gauge tap 501, and bias voltage provides gauge tap 502, and ground voltage provides on the gauge tap 503 and to connect a plurality of driving voltages switch 500 is provided.For example, as Fig. 5 b, 3 driving voltages provide switch, and (500a, 500b 500c) provide gauge tap 501 at the 1st node and data voltage, and bias voltage provides gauge tap 502, and ground voltage provides gauge tap 503 to connect jointly.Also have, each driving voltage provides switch, and (500a, 500b 500c) are connected with different addressing electrodes (X) separately.That is, driving voltage provides switch 500 to be connected with the Xa addressing electrode, and driving voltage provides switch 500 to be and the Xb addressing electrode, and driving voltage provides switch to be connected with the Xc addressing electrode.
And, the driving voltage of such plural number provides switch (500a, 500b, 500c) easiness in order to control, form such field effect transistor internal body diodes (Da, Db with each field effect transistor (Field Effect Transistor:FET), Dc) each positive pole (Anode) terminal is addressing electrode (X) direction of Plasmia indicating panel, and negative pole (Cathode) is that gauge tap (501) direction is provided is good to data voltage.
Here, described plural driving voltage provide switch (500a, Qa), (500b, Qb), (500c is to provide gauge tap 501, S1 with each data voltage Qc), ground voltage provides gauge tap 503, S3 and bias voltage provide gauge tap 502, and S2 is independent mutually, constitute a module (Module) separately for good.That is, such driving voltage provide switch (500a, Qa), (500b, Qb), (500c, Qc) be a data drive integrated circult (Data Drive IC) independent with other on-off elements.
As Fig. 5 b, be connected the on-off element of addressing (X), promptly, driving voltage provides switch, and (500c) quantity reduces to 1 from existing 2 shown in Figure 3 for 500a, 500b, reduce employed on-off element quantity on the whole plasma display system, reduce manufacturing cost.For example, the addressing electrode that forms on the Plasmia indicating panel is altogether 100 the time, as the existing plasma display system of Fig. 3 in order to drive this 100 addressing electrodes, at least need 200 on-off elements, but as Fig. 5, plasma display system of the present invention is to provide switch (500a with 100 driving voltages one by one that are connected addressing electrode separately, 500b, 500c) 50, data voltage provides gauge tap (501, S1) 1, bias voltage provides gauge tap, and (502, S2) 1, ground voltage provides gauge tap (503 in addition, S3) 1,53 on-off elements drive 100 addressing electrodes altogether.
The action of the 1st embodiment of such plasma display system of the present invention and Fig. 6 combine and see, as follows: in the 1st examples of implementation of the plasma display system of the present invention here, only switch is provided (situation of Fig. 5 b 500c) describes for 500a, 500b at having a plurality of driving voltages., be why because Fig. 5 b is the situation that comprises Fig. 5 a only for the example of 5b.
Fig. 6 is the action for the plasma display system of the present invention of key diagram 5b, the process flow diagram of expression action.When Fig. 6 article on plasma display device drove, the particular data Pattern that is provided to addressing electrode (X) carried out diagram and explanation.In this statement, this is just for convenient to explanation of the present invention, and plasma display system of the present invention does not limit to and the moving of data pattern shown in Figure 6.
As figure, between addressed area, give when importing the data pulse of data voltage (Va) on Xa addressing electrode and the Xc addressing electrode, data voltage provides gauge tap 501, S1 is an opening, and bias voltage provides gauge tap 502, and S2 keeps closed condition, ground voltage provides gauge tap 503, and S3 is a closed condition.Under such state, driving voltage provides switch 500a and driving voltage to provide switch 500c to open, and driving voltage provides switch 500b to keep closed condition.
Thereupon, the data voltage that the data power supply provides (Va) is to provide gauge tap 501 through data, and S1 and driving voltage provide switch 500a and 500c to be provided to Xa addressing electrode and Xc addressing electrode.The data pulse of data voltage (Va) is provided on Xa addressing electrode and the Xc addressing electrode like this.At this moment, the corresponding discharge cell on Xa addressing electrode and the Xc addressing electrode is by addressing (Addressing).

Like this, when the voltage of the 1st node (node) became bias voltage (Vb), Xa addressing electrode and Xc addressing electrode voltage were data voltage (Va), thus Xa addressing electrode and Xc addressing electrode voltage ratio the 1st node (node) (n1) voltage is higher.
Here, described driving voltage provide switch 500a and driving voltage that switch 500c internal body diodes is provided (Da, direction Dc) is that (Xa is Xc) to the suitable direction of the 1st node (n1) from addressing electrode.In other words, such internal body diodes (Da, Dc) positive pole (Anode) is towards addressing electrode (X), negative pole (Cathode) provide gauge tap 501 towards data voltage, S1, therefore, through such internal body diodes (Da, Dc), the voltage transitions of described Xa addressing electrode and Xc addressing electrode becomes bias voltage (Vb).
Like this, bias voltage (Vb) is to provide switch (500a according to described driving voltage, 500b, internal body diodes (Da 500c), Db, Dc) addressing electrode (X) voltage is set, so driving voltage provides switch 500a, driving voltage provide switch 500b and driving voltage provide switch 500c be open or closed condition all it doesn't matter.In order to represent that driving voltage provides switch 500a, driving voltage provides unlatching that switch 500b and driving voltage provide switch 500c or closed condition, and it doesn't matter, represents with X in the grid among Fig. 6.
For the addressing electrode (X) of importing data pulse carries out initialization, the interval that stops to import data voltage (Va) data pulse on the addressing electrode (X) is called the interval of stopping (d2).The interval (d2) of stopping is that the data voltage that addressing electrode (X) is gone up the data pulse of input data voltage (Va) provides interval (d3) afterwards.
Provide interval (d3) at data voltage, when importing the data pulse of data voltage (Va) on the Xb electrode between addressed area, turn-on data voltage provides gauge tap 501, S1, closing bias voltage provides gauge tap 502, S2, ground voltage provides gauge tap 503, and S3 keeps closed condition.Described here ground voltage provide switch (503, S3) between addressed area, keep closed condition always.
Under such state, driving voltage provides switch 500b, Qb to open, and driving voltage provides switch 500a, Qa and driving voltage to provide switch 500c, Qc to close.
Thereupon, data voltage (Va) that the data power supply is provided provides switch 501 through data voltage, S1 and, driving voltage provides switch 500b, Qb to be input to the Xb addressing electrode.Just import the data pulse of data voltage (Va) to the Xb addressing electrode.Thereupon, corresponding discharge cell on the Xb addressing electrode by addressing (addressing) at this moment, it is to be exactly closed condition when bias supply is accepted bias voltage (Vb) that the driving voltage of 500a provides the driving voltage of switch (Qa) and 500c that switch (Qc) is provided, it is greater than ground voltage (GND), less than change (Floating) in the scope of data voltage (Va) that the driving voltage that the driving voltage that is connected 500a provides the addressing electrode (Xa) of switch (Qa) and is connected to 500c provides the addressing electrode (Xc) of switch (Qc).
In other words, provide interval at such d3 data voltage, Xa addressing electrode and Xc addressing electrode are changes (Floating) under the state of input bias electrode (Vb).Therefore, Xa addressing electrode and Xc addressing electrode are the magnitudes of voltage that keeps being fit to produce address discharge.
Be more preferably, it is that data voltage provides gauge tap 501 between addressed area that the driving voltage that the driving voltage that is connected to 500a provides the addressing electrode (Xa) of switch (Qa) and is connected to 500c provides the addressing electrode (Xc) of switch (Qc), keeps bias voltage (Vb) under the S1 closing state.Thereupon, Xa addressing electrode and Xc addressing electrode are the magnitudes of voltage that keeps being fit to not produce address discharge.
In addition, the driving voltage of 500a provides the driving voltage of switch (Qa) and 500c to provide the size of the switch load that (Qc) is loaded with (Load) to be, as shown in Figure 3, the load that on-off element was loaded with is data voltage (Va) on existing plasma display system; On the contrary, shown in Fig. 5 b, it is the poor of data voltage (Va) and bias voltage (Vb) that the driving voltage of 500a provides the driving voltage of switch (Qa) and 500c that the switch load (Load) that (Qc) is loaded with is provided.That is Va-Vb.This is because between addressed area, for the addressing electrode of the data pulse of input data voltage (Va) is to be kept by the change (Floating) of bias voltage (Vb).
As a result, in the plasma display system of the present invention, load that on-off element was loaded with existing technology that compares is little, thereby the withstand voltage of each on-off element is relatively little also out of question.In other words, in plasma display system of the present invention, the voltage endurance of each on-off element is relatively little also to have no relations.For example, tentation data voltage (Va) is 60V, and when bias voltage (Vb) was 30V, this possessed 60V-30V each on-off element of plasma display system of the present invention, and promptly the voltage endurance of 30V gets final product.Just reduce the manufacturing cost of plasma display system.D1 data voltage discussed above is kept the interval, the d2 interval of stopping, and the d3 data voltage is kept in the interval, and described bias voltage provides switch 502, and S2 provides interval d1 at data voltage, and the interval of stopping (d2) between the d3 is an opening.That is, bias voltage provides gauge tap 502 in the interval of stopping (d2), and S2 opens, and (Xa Xc) carries out initialization to the addressing electrode that provides interval (d1) to import data voltage (Va) to preceding data.
And, further observe described Fig. 6, data voltage provides gauge tap 500 as can be known, and S1 and bias voltage provide gauge tap 502, and S2 is can the while opening.That is, data voltage provides gauge tap 501, and S1 and bias voltage provide gauge tap 502, and when having one to be closed condition among the S2, another is to open (Turn On) state; Data voltage provides gauge tap 501, and S1 and bias voltage are put forward gauge tap 502, and among the S2, when an opening was arranged, another was a closed condition.

As Fig. 7 b, the on-off element that links to each other with addressing electrode (X), promptly, driving voltage provides switch 700a, Qa, 700b, Qb, 700c, Qc reduce to 1 from existing as Fig. 32 and reduce the employed on-off element of whole plasma display system, reduce manufacturing cost.For example, on the whole Plasmia indicating panel formed addressing electrode add up to 100 the time, the plasma display system of existing Fig. 3 needs 200 on-off elements at least in order to drive 100 such addressing electrodes, but the plasma display system of the present invention as Fig. 7 b is that the driving voltage that links to each other one by one on 100 addressing electrodes provides switch 700a, Qa, 700b, Qb, 700c, Qc 50, data voltage provides gauge tap 701,1 of S1, also have ground voltage that gauge tap 702 is provided, 1 of S2 drives 100 addressing electrodes by 52 on-off elements altogether.
To the action of second embodiment of plasma display system of the present invention and Fig. 8 combine describe as follows.Only provide switch 700a, Qa here at a plurality of driving voltages that possess among the 2nd embodiment of plasma display system of the present invention, 700b, Qb, the situation as Fig. 7 b of 700c, Qc illustrates.Because Fig. 7 b comprises the situation shown in Fig. 7 a.
Fig. 8 is the process flow diagram of the plasma display system action of the present invention of key diagram 7b.Fig. 8 diagram also illustrates when plasma display system drives, the specific data pattern (Pattern) that is provided to addressing electrode (X).In this statement, this just is convenient to illustrate the present invention, and plasma display system of the present invention is not to have only data pattern shown in Figure 8 to move.
As Fig. 8, when providing the data pulse of data voltage (Va) between addressed area on Xa addressing electrode and Xc addressing electrode, data voltage provides switch 701, and S1 is an opening, and ground voltage provides gauge tap 702, and S2 is a closed condition.Under such state, it is to open that the driving voltage of 700a provides the driving voltage of switch (Qa) and 700c that switch (Qc) is provided, and it is to keep closed condition that the driving voltage of 700b provides switch (Qb).
Thereupon, the data voltage (Va) that the data power supply is provided provides gauge tap 701 through the data film, and the driving voltage of S1 and 700a and 700c provides switch, and (Qa Qc) is provided to Xa addressing electrode and Xc addressing electrode.At this moment, providing voltage on Xa addressing electrode and the Xc addressing electrode is data voltage (Va) data pulse.Corresponding discharge cell on Xa addressing electrode and the Xc addressing electrode is by addressing (addressing) then.

At this moment, it is exactly closed condition since connection point power receives ground voltage (GND) that the driving voltage of 700a provides the driving voltage of switch (Qa) and 700c that switch (Qc) is provided, therefore, providing the switch addressing electrode that (Qa) links to each other (Xa) with the driving voltage of 700a is in ground voltage (Vb) change (Floating) with providing the switch addressing electrode that (Qc) links to each other (Xc) with the driving voltage of 500c.
In other words, provide interval at the d3 data voltage, Xa addressing electrode and Xc addressing electrode are changes (Floating) under the state that ground voltage (GND) is provided.Just keep the Xa addressing electrode and the Xc addressing electrode is kept the voltage that does not produce address discharge.
In addition, the driving voltage of 700a provides the driving voltage of switch (Qa) and 700c to provide the switch load (Load) that (Qc) is loaded with to be, is data voltage (Va) as load that on-off element was loaded with on the existing plasma display system of Fig. 3; As Fig. 7 b, it is ground voltage (GND) poor of data voltage (Va) and the Floating of institute that the driving voltage of 700a provides the driving voltage of switch (Qa) and 700c that the switch load (Load) that (Qc) is loaded with is provided.That is, (Va-Floating GND).As seen, ground voltage (GND) is kept the Floating state among the 2nd embodiment of described plasma display system of the present invention, and the voltage endurance that each on-off element had is relatively little also passable.Simultaneously, can reduce the manufacturing cost of plasma display system.
D1 data voltage discussed above is kept the interval, the d2 interval of stopping, and the d3 data voltage is kept the interval, and described ground voltage provides gauge tap 702, and S2 provides interval d1 at data voltage, and the interval of stopping (d2) between the d3 is an opening.That is, the interval of stopping (d2) ground voltage provide gauge tap (702, S2) be opening, (Xa Xc) carries out initialization to the addressing electrode that provides interval (d1) that data voltage (Va) is provided at data voltage before.
And, further see described Fig. 8 as can be known, data voltage provides empty verbiage switch 700, and S1 and ground voltage provide gauge tap 702, and S2 does not open simultaneously.That is, data voltage provides gauge tap 701, and S1 and ground voltage provide gauge tap 702, and among the S2, one when being closed condition, another is out the device state; Data voltage provides gauge tap 701, and S1 and bias voltage provide gauge tap 702, and among the S2 one when being opening, another is a closed condition.
As above-mentioned explanation, plasma display system of the present invention is to reduce on-off element than prior art, and the voltage endurance of each on-off element also can drive plasma display system smoothly than prior art is low.
