Description
本申请要求在2003年10月30日提交的韩国专利申请No.10-2003-0076198的优先权,其内容在此处并入列为参考。
技术领域
本发明涉及用于驱动等离子体显示板(PDP)的方法和装置,并且更具体地,涉及用于驱动具有简化的扫描电极驱动电路的PDP的方法和装置。
背景技术
图1是内部透视图,示出了典型的表面放电型三极管PDP,而图2是图1所示的PDP的单个放电单元的剖面图。
参考图1和图2,在表面放电PDP 1的前玻璃基板10和后玻璃基板13之间提供了地址电极线AR1,AG1,...,AGm,ABm、介电层11和15、Y电极线Y1,...,Yn、X电极线X1,...,Xn、磷光层16、阻挡壁17、和保护层12。
在后玻璃基板13的前表面上以预定的图案形成了地址电极线AR1,AG1,...,AGm,ABm。后介电层15覆盖了地址电极线AR1,AG1,...,AGm,ABm。阻挡壁17形成在后介电层15上在地址电极线AR1,AG1,...,AGm,ABm之间并且与地址电极线AR1,AG1,...,AGm,ABm平行。阻挡壁17划分各个放电单元的放电区域,并且防止了放电单元之间的串扰。在后介电层15上和阻挡壁17的两个侧面上形成了磷光层16。
在前玻璃基板10的后表面上成对地形成了X电极线X1,...,Xn和Y电极线Y1,...,Yn,以便正交于地址电极线AR1,AG1,...,AGm,ABm,并且它们的交点定义了放电单元。每条X电极线X1,...,Xn和Y电极线Y1,...,Yn可以包括由透明导电材料,例如氧化铟锡(ITO)形成的透明电极部分X1a,...,Xna和Y1a,...,Yna,和金属电极部分X1b,...,Xnb和Y1b,...,Ynb,用于增加电导率。前介电层11覆盖了X电极线X1,X2,...,Xn和Y电极线Y1,Y2,...,Yn。可以由氧化镁(MgO)层形成的保护层12保护面板1免于受到强电场的影响,并且其被淀积在前介电层11上。在放电空间14中气密性密封了用于形成等离子体的气体。
美国专利No.5,541,618公开了用于驱动具有图1所示结构的PDP的地址-显示分离(ADS)的方法。
图3是用于图1的PDP 1的典型驱动装置2的框图。参考图3,驱动装置2包括图像处理器26、逻辑控制器22、地址驱动器23、X驱动器24、和Y驱动器25。图像处理器26将外部模拟图像信号转换为内部图像信号,例如,8位红色(R)视频数据、8位绿色(G)视频数据、8位蓝色(B)视频数据、时钟信号、垂直同步信号、和水平同步信号。逻辑控制器22响应来自图像处理器26的内部图像信号产生驱动控制信号SA、SY和SX。
地址驱动器23处理地址信号SA以产生显示数据信号,并且将该显示数据信号施加到地址电极线。X驱动器24处理X驱动控制信号SX并且将结果施加到X电极线。Y驱动器25处理Y驱动控制信号SY并且将结果施加到Y电极线。
图4是示出了驱动图1 PDP 1的ADS方法的时序图。参考图4,为了实现时分灰阶显示,单位帧可以分为多个子域SF1,...,SF8。单独的子域SF1,...,SF8可以进一步分别分为复位周期R1,...,R8、寻址周期A1,...,A8、和维持周期S1,...,S8。
PDP 1的亮度与单位帧中的维持周期S1,...,S8的总长度成比例,其为255T(T是时间单位)。时间2n-1被设定为第n个子域SFn的维持周期Sn。这样,通过适当地选择子域来显示,可以执行256灰阶,包括灰阶0的显示。
图5是示出驱动信号示例的时序图,该驱动信号以图4所示的单位子域施加到图1所示的PDP 1的电极线。
在图5中,参考数字SAR1...ABm是施加到地址电极线(图1的AR1,AG1,...,AGm,ABm)的驱动信号,SX1...Xn是施加到X电极线(图1的X1,...,Xn)的驱动信号,而SY1...Yn是施加到Y电极线(图1的Y1,...,Yn)的驱动信号。
参考图5,单位子域SF包括复位周期PR、寻址周期PA、和维持周期PS。在复位周期PR中,施加到X电极线X1,...,Xn的电压从地电压VG上升到第一电压Ve,并且同时地电压VG施加到Y电极线Y1,...,Yn和地址电极线AR1,AG1,...,AGm,ABm。
接着,施加到Y电极线Y1,...,Yn的电压从第二电压VS(例如,155V)上升到最大电压(VSET+VS)(例如,355V),并且同时地电压VG施加到X电极线X1,...,Xn和地址电极线AR1,AG1,...,AGm,ABm。
接着,当施加到X电极线X1,...,Xn的电压维持在第二电压VS时,施加到Y电极线Y1,...,Yn的电压从第二电压VS减小到地电压VG,而同时将地电压VG施加到地址电极线AR1,AG1,...,AGm,ABm。
这样,在寻址周期PA中,当向地址电极线AR1,AG1,...,AGm,ABm施加显示数据信号时,地电压VG的扫描信号顺序地施加到偏置在第四电压VSCAN的Y电极线Y1,...,Yn,由此地址Y电极线Y1,...,Yn。将地址电压VA的显示数据信号施加到地址电极线AR1,AG1,...,AGm,ABm来选择各个放电单元,并且在对应的放电单元未被选中时,地电压VG施加到地址电极线。这样,在将地电压VG施加到对应的Y电极时将地址电压VA施加到地址电极,由于地址放电而在对应的放电单元中产生了壁电荷。为了促进该地址放电,在寻址周期中X电极线X1,...,Xn可以维持第一电压Ve。
在维持周期PS中,第二电压VS的维持脉冲交替地施加到Y电极线Y1,...,Yn和X电极线X1,...,Xn,由此,在寻址周期PA中所选择的这些放电单元中激发了显示放电。
图6是用于驱动PDP的传统装置的Y驱动器的电路图,图7是示出了施加到扫描驱动集成电路(IC)的扫描控制信号的示例的时序图,而图8是示出了驱动PDP的传统方法中所使用的扫描控制信号的示例的时序图。
参考图6,Y驱动器25处理Y驱动控制信号SY用以产生显示数据信号,并且将其施加到Y电极线。Y驱动器25可以包括电路部分和扫描驱动IC 251。电路部分在复位周期PR中、寻址周期PA中和维持周期PS中将不同的电压(例如,Vs、Vset或者Vscan)施加到Y电极线。扫描驱动IC 251在寻址周期PA期间能够将扫描脉冲顺序地施加到Y地址线。
扫描驱动IC 251可以包括多个输出端,并且对于每条Y地址线可以形成一个扫描驱动IC。
扫描驱动IC 251接收如图7所示的扫描控制信号,并且在寻址周期期间将扫描脉冲输出到Y电极线。尽管可以依赖于扫描驱动IC251的类型改变扫描驱动信号,但是它们典型地包括时钟信号CLK、数据信号Data、选通信号STB、消隐信号BLK、和高阻抗控制信号HIZ。
扫描驱动IC 251在寻址周期PA期间向Y电极线输出扫描脉冲,并且在维持周期PS和复位周期PR期间放电脉冲和复位脉冲可以通过其内部的二极管路径。因此,如图8所示,扫描驱动IC 251可以被接地在浮动的电势电平上,其随时间变化,而不是绝对的“0”电平。可能需要用于使扫描驱动IC 251的输入控制信号同其输出控制信号电隔离的器件,用以提供该浮动地。
通常,可以使用光耦合器或者变压器使扫描驱动输入信号同输出信号电隔离。用于驱动PDP的典型装置利用了光耦合器252,如图6所示。然而,在批量生产PDP时,提供光耦合器252可能会增加元件的离散和缺陷产品,由此降低了产量。

具体实施方式
下文通过参考附图描述了本发明的示例性实施例。
图9是示出了根据本发明的示例性实施例的驱动PDP方法的时序图,而图13是示出了根据本发明的方法中所使用的扫描驱动信号的示例的时序图。
参考图9,在复位周期PR和维持周期PS期间,Y电极线Y1,...,Yn维持在参考电平GND。在寻址周期PA期间,Y电极线Y1,...,Yn偏置在第一电平Vscan,同时参考电平GND的扫描信号顺序施加到其上。
在复位周期PR期间,Y电极线Y1,...,Yn处于参考电平GND,地址电极线AR1,AG1,...,AGm,ABm也维持在参考电平GND,并且从第二电平Vs下降至第三电平Vs+Vset的下降斜脉冲施加到X电极线X1,...,Xn,并且然后从参考电平GND上升至第四电平Ve的上升斜脉冲施加到X电极线X1,...,Xn。
在寻址周期Pa期间,X电极线X1,...,Xn维持在第四电平Ve,而Y电极线Y1,...,Yn偏置在第一电平Vscan。参考电平GND的扫描信号顺序施加到Y电极线Y1,...,Yn用以地址Y电极线Y1,...,Yn,并且地址电压VA施加到待显示的放电单元的地址电极线AR1,AG1,...,AGm,ABm。地址电极线与施加到Y电极线Y1,...,Yn的扫描信号同步。
在维持周期PS期间,各自具有处于第二电平VS的电压的正维持脉冲和负维持脉冲交替地施加到X电极线X1,...,Xn,而同时Y电极线Y1,...,Yn和地址电极线AR1,AG1,...,AGm,ABm维持在参考电平GND。
因此,根据本发明的第一示例性实施例,扫描脉冲施加到Y电极线Y1,...,Yn,而维持脉冲和复位脉冲施加到X电极线X1,...,Xn。
因此,在根据第一示例性实施例的驱动PDP的方法中,用于Y电极的扫描驱动IC仅需要产生扫描脉冲。因此,用于产生复位放电和维持放电的电路部分不是必需的。因此,与传统的PDP驱动装置不同,该扫描驱动IC使用绝对的地取代浮动的地。因此,不再需要用于电隔离扫描驱动IC以产生浮动地的隔离器件。
结果,典型地用作典型PDP驱动装置的隔离器件的光耦合器(图6的252)不再需要,这在大量生产PDP时可以增加产量。
而且,由于扫描驱动IC可以使用绝对地取代浮动地,因此在绝对地GND的基础上,施加到扫描驱动IC的扫描控制信号甚至可以具有仅需用于寻址周期的信号电平。
图13示出了根据本发明的第一示例性实施例的扫描控制信号的示例,其基于绝对地而不是浮动地而施加。与图8相比较,低电平信号0UTL、高电平信号OUTH和时钟信号CLK具有绝对地GND的电平。
图10是示出了根据本发明的第二示例性实施例的驱动PDP方法的时序图。
与第一示例性实施例不同,如图10所示,复位脉冲和维持脉冲可以施加到Y电极线Y1,...,Yn。在复位周期PR的第一部分中,Y电极线Y1,...,Yn在参考电平GND的基础上维持在第一电平Vscan,并且在复位周期PR的第二部分期间,将它们维持在参考电平GND。在寻址周期PA期间,Y电极线Y1,...,Yn偏置到第一电平Vscan,并且参考电平GND的扫描信号顺序施加到其上。在维持周期PS期间,第一电平Vscan的Y维持脉冲Pys施加到Y电极线Y1,...,Yn。
在复位周期PR的第一部分中,从第五电平V5下降至第六电平V6的下降斜脉冲施加到X电极线X1,...,Xn,并且然后在第二部分中,从参考电平GND上升至第四电平Ve的上升斜脉冲施加到其上。在复位周期PR中,地址电极线AR1,AG1,...,AGm,ABm(未示出)维持在参考电平GND。
第二示例性实施例的寻址周期PA的执行与第一示例性实施例的寻址周期PA相似;因此,在这里不作进一步的讨论。
在维持周期PS期间,具有基于参考电平GND的第二电平Vs的正维持脉冲Pps、和具有基于参考电平GGND的第五电平V5的负维持脉冲Pms交替地施加到X电极线X1,...,Xn。而且,具有基于参考电平GND的第一电平Vscan的Y维持脉冲Pys施加到Y电极线Y1,...,Yn。地址电极线AR1,AG1,...,AGm,ABm(未示出)维持在参考电平GND。
优选地,在负维持脉冲Pms施加到X电极线X1,...,Xn的同时,将Y维持脉冲Pys施加到Y电极线Y1,...,Yn。换言之,优选的是,Y维持脉冲Pys的电平和负维持脉冲Pms的电平之间的差等于电压Vs,其是对于传统维持脉冲的典型值。
因此,第五电平V5优选地对应于第一电平Vscan和第二电平Vs之间的差。在此情况中,在第一复位周期期间的X电极和Y电极之间的电学关系可以与传统情况中的相同。
由于通过参考图10所述的第二示例性实施例执行了与通过参考图9所述的第一示例性实施例相同的功能,因此在这里不再重复关于其内容的详细描述。
图11是示出了根据本发明示例性实施例的用于驱动PDP的装置的框图,图12是示出了图11所示装置的扫描驱动器的框图,而图14是示出了图11所示PDP的X驱动器和Y驱动器的电路图。
参考图11,用于驱动PDP的装置4包括控制器41、Y驱动器45、地址驱动器42、复位/维持电路44和X驱动器43。包括X电极线X1,...,Xn和Y电极线Y1,...,Yn的平行的维持电极线对交替地排列,并且设置为与地址电极线AR1,AG1,AB1...正交。维持电极线和地址电极线之间的交点定义了放电单元Cij。
控制器41处理输入图像数据以产生扫描控制信号、地址控制信号、复位/维持控制信号、和公共控制信号。Y驱动器45响应扫描控制信号,将扫描驱动信号施加到Y电极线Y1,...,Yn。地址驱动器42响应地址控制信号,将地址驱动信号施加到地址电极线AR1,AG1,AB1...。复位/维持电路44响应复位/维持控制信号,将复位/维持驱动信号施加到X电极线X1,...,Xn,X驱动器43响应公共控制信号,将公共驱动信号施加到X电极线X1,...,Xn。
Y驱动器可以包括扫描驱动器,其将扫描脉冲施加到Y电极线Y1,...,Yn,以便在寻址周期PA期间地址Y电极线Y1,...,Yn。
这里,输出自控制器41的扫描控制信号没有被电隔离,并且其可以直接输入到扫描驱动器。如图14所示,连接到扫描驱动器451的地可以是绝对地GND。而且,在每个复位周期PR和维持周期PS期间,可将扫描控制信号维持在地电平GND。
X驱动器43可以在复位周期PR和维持周期PS期间向X电极线X1,...,Xn提供复位脉冲和维持脉冲,并且在寻址周期PA期间,将X电极线X1,...,Xn偏置在基于参考电平GND的第四电平Ve。
因此,如图14所示,用于驱动PDP的装置可以包括平板电容器Cp,其具有连接到X驱动器43的一端和连接到Y驱动器45的另一端。
X驱动器43可以包括能量回收器431、维持电压发生器432、复位电路433、和偏置电压发生器434。Y驱动器45可以包括扫描驱动器451,其将扫描电压Vscan施加到Y电极线。
能量回收器431将充电/放电能量回收并充电至平板电容器Cp。维持电压发生器432将正维持电压Vs和负维持电压-Vs施加到X电极线。复位电路433将复位电压施加到X电极线,并且可以包括负斜电压发生器R1。偏置电压发生器434在寻址周期期间将偏置电压施加到X电极线,并且可以包括用于施加偏置电压的斜电压发生器R2。
传统的用于驱动PDP的装置可以使用如图6所示的Y驱动器25,以便向各个电极线施加具有图5所示波形的电压。传统的Y驱动器25可以包括维持电压发生器、包括斜升(ramp)的复位电路、和偏置电压发生器。然而,如图14所示,根据本发明的示例性实施例,X驱动器43包括能量回收器431、维持电压发生器432、复位电路433、和偏置电压发生器434,以便于向各个电极线施加具有图9或10所示波形的电压。
如上文所表明的,传统的用于驱动PDP的装置可能需要能够使用浮动地的光耦合器,以便于向Y电极线施加扫描脉冲、维持脉冲、复位电压和偏置电压。
然而,在根据本发明的示例性实施例的装置中,Y驱动器45包括用于向Y电极施加扫描脉冲的扫描驱动器451,而X驱动器43包括能量回收器431、维持电压发生器432、复位电路433、和偏置电压发生器434。因此,不需要光耦合器。
由于本发明的装置根据图9或者图10所说明的PDP驱动方法驱动PDP,因此这里省略了关于其功能和作用的详细描述。
如迄今所解释的,本发明确实不需要诸如光耦合器的隔离器件,其传统地用于电隔离施加到扫描驱动IC的扫描控制信号。因此,可以简化扫描电极驱动电路。
而且,本发明解决了可能由诸如光耦合器的隔离器件失效而引起的问题,此类问题常发生于传统的批量生产PDP的过程中,因此极大地增加了产量。
而且,在扫描电极中仅执行扫描放电,而不是复位或者维持放电时,可以很容易地设计集成了X电极和Y电极的驱动器板。
而且,由于不需要诸如光耦合器的隔离器件,其占据了PDP生产成本中的很大部分,因此可以减小生产成本。
对于本领域的技术人员显而易见的是,在不偏离本发明的精神和范围的前提下,可以对本发明进行不同的修改和变化。这样,目的在于,本发明涵盖了在附属权利要求的范围内提供的本发明的修改和变化以及其等效物。
