交流等离子体平板显示器通过对一个电视场内的脉冲数目调制技术来实现灰度显示。 AC plasma flat-panel display is achieved by a number of pulses of the television field modulation gradation display. 目前普遍采用的驱动方式主要有ADS(AddressDisplay-period Seperation)方式,和CLEAR(hiContrast & LowEnergy Address & Reduction of false contour sequence)方式。 Driving method now widely used mainly ADS (AddressDisplay-period Seperation) mode, and CLEAR (hiContrast & amp; LowEnergy Address & amp; Reduction of false contour sequence) mode. ADS方式将一个电视场分为若干个子场,每个子场又分复位期、寻址期和维持期,不同子场的维持期中维持脉冲的个数不同,有选择地点亮子场就可实现灰度显示。 ADS manner a television field is divided into several subfields, each subfield is divided into a reset period, an address period and a sustain period, the sustain period of the different sub-field different numbers of sustain pulses, the subfields are selectively lit gradation can be achieved display. 如将一场分为8个子场,各子场中维持脉冲数的比例为20、21、22、23、24、25、26、27,可实现256级灰度。 As will be divided into 8 subfields a, the ratio of each subfield, sustain pulses is 20,21,22,23,24,25,26,27, 256 levels of gray can be achieved. 在各子场的复位期中,目前都采取首先加一个全写入脉冲,使得全屏放电,再利用自擦除放电或者宽、窄脉冲擦除放电等方式来擦除壁电荷,使得全屏复位。 In the reset period of each subfield, currently take a full writing pulse is applied first, so that the full screen discharge, self-erase discharge or reuse wide, narrow pulse erase discharges for erasing wall charges, etc., so that the full screen reset. 图三所示为日本富士通公司采用的一种ADS驱动方案,详见美国专利5,446,344。 Figure III represents a typical driving scheme ADS Fujitsu used, see U.S. Patent No. 5,446,344. 图中所示为一个子场中各电极的驱动电压波形,在复位期,首先在X电极上加全写入脉冲Vs+Vw,使X、Y电极间的电位差大于它们之间的放电电压Vfxy,全屏放电,X电极上带负的壁电荷,Y电极上带正的壁电荷,且使X、Y电极间的壁电压也大于它们之间的放电电压,因此在撤去全写入脉冲后,X、Y电极之间在壁电压的作用下产生自擦除放电。 FIG subfield as a driving voltage waveforms of each electrode in the reset period, first full writing pulse applied Vs + Vw on the X electrode, so that X, Y potential difference between the electrodes is greater than the discharge voltage between them after Vfxy, fullscreen discharge, negative wall charges in the X electrode, positive wall charges on the Y electrode, and that the X, the wall voltage between the Y electrode may be greater than the discharge voltage between them, so the full writing pulse removed , X, is generated between the Y electrode under the effect of self-erase discharge wall voltage. 由于器件制造过程中的不均匀性,各显示单元的放电电压存在一定范围的零散。 Due to non-uniformity of device fabrication process, the discharge voltage of each cell shows the presence of a range of scattered. 对于那些没能产生自擦除放电的单元,全写入脉冲后加在Y电极上的维持脉冲Vs可使其壁电荷极性反转,之后,X、Y电极上同时加相反脉冲,X为Va,Y为-Vy,在该脉冲作用下,壁电荷被放大,同时极性再次反转,然后再在Y电极上加斜坡电压擦除脉冲,擦除这部分壁电荷。 For those who are not capable of generating self erase discharge unit, after the full writing pulse is applied to the Y electrode sustain pulse Vs may have its polarity wall charges, then, X, Y electrodes while the pulse applied contrary, X is VA, Y is -Vy, in this pulse, the wall charges are enlarged, while the polarity is reversed again, and then ramp the voltage applied erase pulse, the wall charges erase part in which the Y electrode. 该方案虽可做到有效复位,但是由于每一个子场均需加全写入脉冲,产生全屏放电,全屏放电是与显示图象无关的放电,而且亮度大,导致背景显示亮度增大,对比度下降,而且功耗增大。 While this scheme may be effective reset, but since each subfield required plus full writing pulse, discharge is generated full-screen, full-screen discharge is a discharge regardless of the display image, and the brightness is large, resulting in increased background display brightness, contrast decline, and power consumption increases. 另外,斜坡电压擦除脉冲产生小规模放电,放电后仍可保留小部分壁电荷,其极性与放电前相同,此处,Y电极在擦除脉冲后仍带有小部分正电荷,极性与寻址时所加寻址电压极性相反,不利于低压寻址。 Further, erasing ramp voltage pulse generating small-scale discharge, the discharge may retain a small portion of the wall charges whose polarity is the same as the pre-discharge, where, Y electrodes remain after the erase pulse having a small partial positive charge, polarity, when addressing the applied address voltage of opposite polarity, it is not conducive to low voltage addressing.

图四所示为CLEAR驱动方式示意图,详见NIKKEI ELECTRONICS1999.10.25(NO.755)中驅動法ゃセル構造を變えてPDPの畫質を高めゐ一文。 As shown in Figure IV is a schematic CLEAR driving method, see NIKKEI ELECTRONICS1999.10.25 (NO.755) driving method in Daicel configured ゃ variant e te wo wo high quality PDP の Circular ru article. 该方式将一场分为12个子场,每个子场包括寻址期和显示期,各显示期中维持脉冲数完全相等。 The embodiment will be divided into a 12 subfields, each subfield including an address period and a display period, each display period exactly equal to the number of sustain pulses. 每一场仅在开始处有一个复位期,且每一场仅复位期全屏放电一次,因此背景亮度低对比度高,复位期使所有像素单元带上相同的壁电荷。 Only every game at the beginning of a reset period, and each of a full-screen reset discharge only once, the high brightness of the background low contrast, all of the pixel cells to reset the same wall charge belt. 其后在各子场的寻址期利用擦除脉冲将不该点亮单元的壁电荷擦除,由于各显示单元放电电压存在一定范围的零散,擦除脉冲的动态范围小,采用擦除式寻址方式的寻址准确率不及写入式寻址方式。 Then using the address period of each subfield of the wall charges erase pulse should erase the lighting unit, each display cell by the presence of a range of discharge voltage fragmented, small dynamic range of erase pulses used to erase the formula addressing addressing accuracy of less than a write-addressing. 在其后的显示期,未被擦除壁电荷的单元在维持脉冲的作用下继续点亮,而擦除了壁电荷的单元就不再点亮。 In the subsequent display period, wall charges are not erased in units continue to light in the sustain pulse action, the wall charge erase unit is no longer lit. 因此通过选择各显示单元上擦除脉冲所在子场的位置,就可控制显示灰度。 Therefore, by selecting the position of each display unit is located on an erase pulse subfield, you can control the display gradation. 由于共有12个子场,可显示12级灰度,若要显示256级灰度,还需通过dither法或误差扩散理论对显示数据进行处理,这就必然要增加显示数据处理电路的复杂性。 Since there are twelve subfields, gray scale 12 may be displayed, to display 256 gray levels, the display data processing needed by diffusion theory dither method or an error, which is bound to increase the complexity of the display data processing circuit.

本发明的目的旨在解决以往驱动方案中存在的这些不足之处,在ADS方式的基础上提出了一种一场只需全屏放电一次的驱动方法,寻址仍采用写入式寻址方式,且在保证准确寻址的前提下,能够增大寻址电压动态范围,并且降低寻址电压。 The present invention is intended to address these deficiencies in the conventional driving scheme, and proposes a method of driving a discharge only once in the full screen mode based on the ADS addressing still using write-mode addressing, in addressing and ensure accurate premise, the address voltage can be increased dynamic range, and reducing the address voltage. 图五为本发明所采用的各电极驱动电压波形图。 Figure V of the present driving voltage waveforms of each electrode used in the invention. 这里作为例子仍将一场分为8个子场,各子场中维持脉冲的比例为20∶21∶22∶23∶24∶25∶26∶27,图中仅给出前两个子场的波形图。 Examples of this will be divided into 8 subfields a, the ratio of each subfield sustain pulse is 20:21:22:23:24:25:26:27, the figure shows only the waveform diagram of the first two sub-fields. 每一个子场仍旧分为复位期、寻址期和维持期。 Each sub-field is still divided into a reset period, an address period and a sustain period. 在第一个子场的复位期,为了使全屏的所有像素单元回复到同一状态,首先加全写入脉冲:X电极加维持电压Vs,Y电极加寻址电压-Vy,两者之间电位差大于它们之间的放电电压Vfxy,全屏放电,X电极带负的壁电荷,Y电极带正的壁电荷,为降低全屏放电的强度,X、Y电极上均采用斜坡电压脉冲,使放电处于小规模状态。 In the reset period of the first subfield, all the pixel units in order to make full-screen return to the same state, the first full writing pulse applied: the potential applied between the X electrode sustain voltage Vs, Y electrode address voltage -Vy applied, both difference is greater than the discharge voltage Vfxy between them, fullscreen discharge, wall charges having the negative electrode X, Y electrodes with positive wall charges reduce the strength of the full screen is discharged, X, are made of a ramp voltage pulse to the Y electrode, the discharge is small state. 全写入脉冲后,X电极回到零电位,Y电极加维持脉冲Vs,维持电压加上X、Y电极间的壁电压大于放电电压Vfxy,再次全屏放电,壁电荷极性反转,X电极为正,Y电极为负。 After full writing pulse, X back to the zero potential electrode, Y electrode sustain pulse Vs of the addition, the sustain voltage plus the wall voltage between the X, Y electrodes is greater than the discharge voltage Vfxy, full screen again discharge, wall charges polarity reversal, X electrode is positive, Y is a negative electrode. 然后给X、Y电极加擦除脉冲,擦除屏上壁电荷,以便在寻址期能够实现写入式寻址。 Then to the X, Y electrodes applied erase pulse, the wall charges erase the screen, in order to enable the address of the write-in address. 擦除脉冲采用斜坡电压脉冲,X电极为+Vsc斜坡电压脉冲,Y电极为-Vy斜坡电压脉冲;或者X电极直接加+Vsc电压,Y电极加-Vy斜坡电压脉冲。 Using a ramp pulse erase voltage pulse, X + Vsc electrodes ramp voltage pulse, Y electrode voltage -Vy ramp pulse; or X + Vsc applied direct voltage electrode, Y electrode voltage applied ramp pulse -Vy. 采用这种斜坡电压脉冲的好处如下:一方面,由于器件制造过程中的不均匀性,使各显示单元的放电电压存在一定范围的零散,因此对于方波型宽及窄擦除脉冲,前者可能擦除不彻底,后者则可能擦除过度(形成极性相反的壁电荷),导致寻址期间发生误写入,而采用斜坡电压脉冲擦除就可有效避免上述情况。 The advantage of using such a ramp voltage pulse is as follows: on the one hand, due to the unevenness of the device manufacturing process, the discharge voltage of each display unit is present in a range of fragmented, thus for square wave pulse width and narrow erase, the former may be is not completely erased, the latter may excessively erased (polarity wall charges are formed opposite to), resulting in the occurrence of erroneous write address period, a ramp voltage pulse is employed to avoid the above situation can be effectively erased. 首先因为斜坡电压脉冲放电为小规模放电,放电后壁电荷极性不会反转,所以不会产生擦除过度的情况;其次在斜坡电压脉冲的末端,X、Y电极间所加电压差为Vsc+Vy大于维持电压Vs,因此对于寻址时未被写入壁电荷的单元,维持脉冲到来时不会产生误放电;另外由于擦除脉冲末端X、Y电极上的电位恰与寻址期扫描到的行上的电位情况一致,所以寻址时不该点亮的单元不会因为X、Y电极间的电位差产生误放电,这样就确保了有效地擦除。 First, because the ramp voltage pulse discharge is small discharge, discharge of the rear wall charge polarity is not reversed, so that no excessively erased; followed between the end of the ramp voltage pulse, X, Y electrode voltage difference is applied Vsc + Vy greater than Vs of the sustain voltage, so wall charges respect to the addressed cell is not written, erroneous discharge does not occur when the sustain pulse arrives; in addition, as the end of the erase pulse X, the potential at the Y electrodes and the address of just where the same potential to the scan line, so should not lit when the addressed cells since the potential difference between the X, Y electrodes to generate erroneous discharge, thus ensuring efficient erasure. 另一方面,由于斜坡电压脉冲放电是在X、Y电极紧邻的区域上小规模进行,所以只有紧邻区域的壁电荷被中和,而在X、Y电极的远离区域仍可保留一些原来极性的壁电荷,且其极性与寻址时寻址脉冲的极性一致,因此对于实现低压寻址十分有利。 On the other hand, since the ramp voltage pulse discharge is small in the X, Y electrodes immediately adjacent area, only the region close to the wall charges are neutralized, and the X, Y electrodes away from the region may still retain some of the original polar wall charges and the polarity address pulse having identical polarity when addressing and therefore very advantageous for achieving low voltage addressing. 进入寻址期,X电极上始终加Vsc的电压,Y电极上逐行扫描,扫描到的行加扫描电压-Vy,未扫描到的行及扫描过的行加-Vsc电压,寻址电极A则根据扫描到的行上的显示数据有选择的在相应列上加寻址电压Va。 Entering the address period, voltage Vsc is always applied to the X electrode, the Y electrode progressive scan, the scan voltage -Vy of a scan line applied, not to the row scanning lines and scanned applied voltage -Vsc, the address electrode A the display data on the scanned row selectively applied on the corresponding column address voltage Va. 对于子场中需要点亮的单元,寻址电极A与扫描电极Y在扫描到时电位差为Va+Vy大于它们之间的放电电压Vfay,产生放电,放电后A电极与X电极上带负的壁电荷,Y电极上带正的壁电荷,因此显示数据就以壁电荷的形式记忆在屏上。 Required for the lighting unit subfield, the address electrode A and scanning electrode Y when the scanning potential difference Va + Vy higher than the discharge voltage Vfay therebetween, discharge is generated with the negative electrode on the A electrode and the X discharge wall charged, positive wall charges on the Y electrode, so the data is displayed in the form of a wall charge on the memory screen. 在寻址期令X电极上的电位Vsc=Va,可使寻址放电时产生的负电荷尽可能多地吸附在X电极上成为对维持放电有用的壁电荷。 In the address period so that the potential at the X electrode Vsc = Va, the negative charge can make the address discharge generated at the time as much as possible to the X electrode adsorbing a useful wall charge of the sustain discharge. 另外扫描过的行上X、Y电极间所加电位差为2Vsc,而且极性与所写入的与显示数据有关的壁电荷的极性相反,使壁电荷能够稳定地吸附在显示电极上,以待维持期到来。 Further on the scanned line X, between Y electrodes a potential difference is applied 2Vsc, but opposite polarity to the polarity of the wall charges associated with the display data written, so that the wall charges can be stably adsorbed on the display electrodes, pending the arrival of the maintenance period. 到了维持期,Y、X电极上交替加维持脉冲Vs,第一个维持脉冲的极性与寻址时写入的壁电荷的极性相同,其和大于它们之间的放电电压Vfxy,产生维持放电,壁电荷极性反转,再与下一个维持脉冲迭加,再次产生维持放电,依次类推就可显示出图像。 To sustain period, Y, are applied alternately pulse Vs of the sustain electrode X, the wall charges of the same polarity as the polarity of the writing and addressing a first sustain pulses, which is greater than the discharge voltage Vfxy between them, the sustain discharge, wall charges polarity inversion, and then the next superimposed sustain pulse, sustain discharge is generated again, and so an image can be displayed. 在维持期,A电极上始终加电压Vaw=Vs/2,使其对正负离子的吸引程度相同,避免其上积累壁电荷。 In the sustain period, the voltage is always applied Vaw = Vs / 2 on the A electrode, so that the same level of attraction of positive and negative ions, which prevent the accumulation of wall charges. 这里我们将维持脉冲的个数选为奇数个,如:21-1、22-1、23-1、24-1、25-1、26-1、27-1、28-1,使最后一个维持脉冲加在Y电极上。 Here we will maintain the number of pulses selected as an odd number, such as: 21-1,22-1,23-1,24-1,25-1,26-1,27-1,28-1, the last one sustain pulse applied to the Y electrode. 这样在维持期结束时,对于那些在该子场中被点亮的单元,X电极带正的壁电荷,Y电极带负的壁电荷,这恰与复位期中维持脉冲后壁电荷的极性一致;而对于那些未被点亮的单元,壁电荷仍处于复位期中擦除脉冲后的状态。 Thus at the end of the sustain period, to those in the sub-field unit to be lit, positive wall charges of the X electrode, wall charges having the negative electrode Y, the sustain pulse just this rear wall charges in the reset period and the polarity coincides ; for those elements is not illuminated, the wall charges remain in the state after the reset period of the erase pulse. 因此,当下一个子场的复位期到来时,无需再从全写入脉冲开始,而只需从擦除脉冲开始即可。 Therefore, when the next reset period of one subfield of arrival, no need to start from the full write pulse, but only from the beginning to erase pulses. 上一场中被点亮单元的壁电荷将被有效擦除,而未被点亮单元的壁电荷本身已处于上一场中被擦除时的状态,未再发生变化,因此就可实现一场仅全屏放电一次,极大地降低了显示的背景亮度,提高了对比度,并可在一定程度上减小功耗。 Last was lit cells will be effectively erased wall charges, while the unit is not illuminated wall charge itself in a state where the upper is erased, no further changes occurred, and therefore can achieve a only one full-screen discharge field, greatly reducing the background brightness of the display, contrast is improved, and power consumption is reduced to some extent.

综上所述,本发明是关于三电极表面放电型交流等离子体平板显示器的驱动方法,在ADS方式的基础上提出了一种一场仅全屏放电一次的驱动方案。 In summary, the present invention relates to a method for driving a three-electrode surface discharge type AC plasma flat panel displays, on the basis of the ADS method presents a full-screen only discharged once a drive scheme. 在本方案中,一个显示场被分为若干个子场,每个子场又分复位期、寻址期和维持期。 In the present embodiment, one display field is divided into several subfields, each subfield is divided into a reset period, an address period and a sustain period. 第一个子场的复位期包括一个全写入脉冲,一个维持脉冲和一个擦除脉冲,其它子场的复位期均只有一个擦除脉冲。 The reset period of the first subfield includes a full writing pulse, a sustain pulse and an erasing pulse, the reset period of the other subfields have only one erase pulse. 全写入脉冲采用分别加在X、Y电极上的斜坡电压脉冲,X为+Vs,Y为-Vy,全屏放电,X电极带负壁电荷,Y电极带正壁电荷。 Respectively, using full writing pulse applied to the X, Y electrode voltage pulse ramp, X is + Vs, Y discharged to -Vy, full screen, X electrode negative wall charges, Y electrodes with positive wall charges. 其后的维持脉冲令壁电荷极性反转。 Subsequent sustain pulses so that a wall charge polarity reversal. 擦除脉冲或者采用分别加在X、Y电极上的斜坡电压脉冲,X为+Vsc,Y为-Vy;或者采用X电极上直接加+Vsc电压,Y电极上加-Vy斜坡电压脉冲。 Or with erase pulse are applied to the X, Y electrode voltage pulse ramp, X + Vsc is, -Vy is Y; or with the X electrode is directly applied + Vsc voltage applied to the Y electrode ramp voltage pulse -Vy. 擦除脉冲末端X、Y电极电位与它们在寻址期中被扫描到时电位一致,且擦除脉冲后Y电极所带壁电荷极性与其在寻址期所加脉冲极性相同。 The end of the erase pulse X, Y electrode potential when they are consistent with the potential is scanned into the address period, the erase pulse and the Y electrode carried by the wall charge polarity of the same address in its polarity pulses applied. 寻址期仍采用写入式寻址方式。 Still uses the address of the write-addressing. 维持期中维持脉冲的个数为奇数,使维持期结束时被点亮单元壁电荷的极性与复位期中维持脉冲后壁电荷的极性相同。 The number of sustain pulses of the sustain period is an odd number, so that the lighting unit is the wall charges at the end of the sustain period and the reset period of the same polarity as the polarity of the sustain pulse of the rear wall charge. 本发明能够降低背景亮度,提高对比度,减小功耗,还可增大寻址电压动态范围,并在保证准确寻址的前提下,降低寻址电压。 The present invention is capable of reducing the background brightness, enhance the contrast, reduce power consumption, the address voltage may also increase the dynamic range, and ensure accurate addressing the premise of reducing the addressing voltage.

4.根据权利要求书1,在第一个子场的复位期中,维持脉冲之后,以及其它子场的复位期中加擦除脉冲。 According to claims 1, in the reset period of the first subfields, after the sustain pulse, and a reset period of the other subfields applied erase pulse. 擦除脉冲的特征是采用分别加在X、Y电极上的斜坡电压脉冲,且斜坡电压脉冲末端的电位与X、Y电极在寻址期中被扫描到时的电位一致,X为+Vsc,Y为-Vy。 Characterized by the use of the erase pulse are applied to the X, Y electrode voltage pulse ramp, and the ramp voltage pulse potential terminal X, Y electrodes are scanned at the same potential in the address period, X is + Vsc, Y as -Vy. 由于斜坡电压脉冲放电为小规模放电,放电后残余壁电荷极性与放电前相同,即X带正壁电荷,Y带负壁电荷,此极性与寻址期中Y电极所加寻址脉冲极性相同。 Since the ramp voltage discharge pulse discharge is small, the residual wall charges after the discharge before discharging the same polarity, i.e. positive wall charges are X, Y and negative wall charges with this polarity of the Y electrode in an address period address pulse applied electrode same sex.
5.根据权利要求书1,在第一个子场的复位期中,维持脉冲之后,以及其它子场的复位期中加擦除脉冲。 According to claims 1, in the reset period of the first subfields, after the sustain pulse, and a reset period of the other subfields applied erase pulse. 擦除脉冲的特征是X电极上直接加+Vsc电压,Y电极上加-Vy斜坡电压脉冲,擦除脉冲末端的电位与X、Y电极在寻址期中被扫描到时的电位一致。 Wherein the erase pulse is applied directly to the voltage + Vsc to the X electrode, the Y electrode voltage applied ramp pulse -Vy, the end of the erase pulse potential and X, Y electrode potential during the address period are scanned to coincide. 由于斜坡电压脉冲放电为小规模放电,放电后残余壁电荷极性与放电前相同,即X带正壁电荷,Y带负壁电荷,此极性与寻址期中Y电极所加寻址脉冲极性相同。 Since the ramp voltage discharge pulse discharge is small, the residual wall charges after the discharge before discharging the same polarity, i.e. positive wall charges are X, Y and negative wall charges with this polarity of the Y electrode in an address period address pulse applied electrode same sex.
6.根据权利要求书1,维持期中维持脉冲的个数为奇数,最后一个维持脉冲加在Y电极上。 According to claims 1, the number of sustain pulses is odd sustain period, a last sustain pulse applied to the Y electrode. 使该子场中被点亮单元在维持期结束时,X电极带正壁电荷,Y电极带负壁电荷,与复位期中维持脉冲后的极性相同;而未被点亮单元中壁电荷的状态维持在该子场复位期中擦除脉冲后的状态,未再发生变化,因此下一子场复位期到来时,仅需从擦除脉冲开始既可。 The sub-field unit is lit at the end of the sustain period, X wall charges with a positive electrode, Y electrode and negative wall charges with the same polarity of the reset period after the sustain pulse; cell wall charge without being lit state is maintained in the state after the reset period of the subfield erase pulse, no further change occurs, therefore when the arrival of the next subfield reset period, an erase pulse can only begin.
