Abstract
本发明公开了一种用于驱动等离子显示面板的方法,其能够改进显示质量。该方法在用于提供驱动波形的数据驱动周期期间和用于将提供驱动波形的电压升高到所需电压的预备周期期间分开地驱动PDP,以在每个放电单元中显示图像,其中在数据驱动周期的维持周期期间提供给电极的波形和在预备周期的维持周期期间提供给电极的波形不同。该方法在维持周期期间不产生维持放电,并且防止当PDP接通时显示由先前状态引起的残留影像,从而改进显示质量。另外,在提供数据驱动波形之前,通过提供地电压给电极1-3秒,优选地2秒,来消除在放电单元中的电荷。因此,防止在整个屏幕上显示残留影像,并且可以改进显示质量。
Description
这个非临时申请要求于2003年12月31日在韩国提交的专利申请No.10-2003-0102174在35 U.S.C.119(a)下的优先权,并且将其整个内容完全包括在这里并作为参考。
技术领域
本发明涉及等离子显示面板,并且特别涉及能够改进显示质量的驱动等离子显示面板的方法。
背景技术
在近来的信息社会中,更加关注作为视觉信息传输介质的显示装置的重要性。广泛使用的阴极射线管或布老恩管沉重并且笨重。但是,正在开发多种能够克服阴极射线管的缺点的平板显示装置。
这些平板显示装置包括等离子显示面板(PDP),场致发射显示器、电荧光显示器等。
这些装置中的PDP,通过在He+Xe,Ne+Xe或He+Ne+Xe的混合气体放电期间产生的147nm紫外线辐射荧光材料来显示包括字符和图形的图像和动画。随着近来的技术进步,这种PDP易于被制造得厚度薄而且尺寸大,而且还易于大大改进图像质量。
具体地说,三电极AC(交流电)表面放电PDP通过使用介质层累积势垒电荷而降低放电需要的电压,并且具有低电压驱动工作和长寿命的优点。
图1是示出了通常的三电极AC表面放电PDP的放电单元的透视图。
参考图1,该PDP的放电单元包括在上基片10上形成的扫描电极Y和维持电极Z,以及在下基片18上形成的寻址电极X。扫描和维持电极Y和Z分别包括透明电极12Y和12Z,并且分别包括行宽度小于透明电极12Y和12Z、并且形成在透明电极12Y和12Z的边缘的金属总线电极13Y和13Z。
形成在上基片10上的透明电极12Y和12Z通常由铟锡氧化物(ITO)制成。在透明电极12Y和12Z上形成的金属总线电极13Y和13Z通常由金属(例如铬(Cr))制成,并用于减少由具有高阻抗的透明电极12Y和12Z引起的电压降。在其中平行形成扫描和维持电极的上基片10上形成上介质层14和保护层16。在上介质层14上形成在等离子放电期间产生的阻挡电荷(barrier charge)。保护层16保护上介质层14不受在等离子放电期间产生的溅射损坏,并且改进次级电子辐射的效率。通常将氧化镁(MgO)用作保护层16。
下介质层22和阻挡条24形成在其上形成寻址电极X的下基片18上。将荧光材料层26涂覆在下介质层22和阻挡条24的表面上。寻址电极X垂直于扫描和维持电极Y和Z。阻挡条24和寻址电极X平行形成,并防止由放电产生的紫外线和可见光泄漏进相邻的放电单元。荧光材料层26用在等离子放电期间产生的紫外线来激励以产生红色、绿色和蓝色可见光中的任意一个。将惰性混合气体注入在上基片10和下基片18以及阻挡条24之间提供的放电空间。
为了实现图像的灰度级,以时分基础驱动PDP,将一帧划分为多个子场,其中每个子场具有不同的辐射数量。每个子场具有用于复位整个屏幕的复位周期、用于选择扫描线并在所选的扫描线中选择单元的寻址周期以及用于根据放电的数量实现灰度级的维持周期。
将复位周期进一步划分为用于提供上升沿波形的建立周期和用于提供下降沿波形的撤除周期。例如,如果希望以256级来显示图像,则将对应于1/60秒的帧周期(16.67ms)划分为八个子场SF1-SF8,如图2所示。将8个子帧SF1-SF8中的每一个进一步划分为如上所述的复位周期、寻址周期和维持周期。对于每个子场,在每一子场中的复位和寻址周期相同,然而维持周期以2n(n=0,1,2,3,4,5,6,7)的比率增加。
图3是示出了PDP的驱动方法的波形图。
参考图3,该PDP根据用于复位整个屏幕的复位周期、用于选择单元的寻址周期和用于维持所选单元的放电的维持周期来单独地驱动。
在复位周期期间,在建立周期期间将上升沿波形同时加到所有扫描电极Y。在这个情况下,扫描电极Y被升高到用于放电单元的电压Vp。通过这个上升沿波形,在整个屏幕的单元中发生弱放电(weakdischarge),并且在单元中创建壁电荷。在提供上升沿波形之后的撤除周期期间,将从低于上升沿波形的峰值电压的正极性电压下降的下降沿波形同时加到所有扫描电极Y。该下降沿波形在单元中产生弱的擦除放电,在整个屏幕的单元中擦除壁电荷中不需要的电荷和由建立放电产生的空间电荷,并且均匀地维持寻址放电需要的壁电荷。
在寻址周期期间,将负极性的扫描脉冲Scan循序加到扫描电极Y,并且在同时将正极性的数据脉冲加到寻址电极。将在扫描脉冲的电压Vy和数据脉冲的电压Va之间的差值加到在复位周期期间产生的壁电压,以在单元中产生寻址放电。在由寻址放电所选的单元中产生壁电荷。
同时,在撤除周期和寻址周期期间,将维持电压电平Vs的正极性直流(DC)电压提供给维持电极Z。
在维持周期期间,将维持电压电平Vs的维持脉冲Sus交替加到扫描电极Y和维持电极Z。然后通过寻址放电将在单元中的壁电压加到维持脉冲Sus,并且无论何时应用每一维持脉冲Sus,在扫描和维持电极Y和Z之间作为表面放电的形式产生维持放电。最后,在完成维持放电之后,将具有窄的脉冲宽度的擦除倾斜波形施加到维持电极Z,擦除单元中的壁电荷。
在上述PDP中,在如图4所示的预备周期中施加预备波形(preliminary waveform),以保证当接通电源时将多个电压源Vp、Vs、Vy和Va升高到所需电压的时间。
在这个情况下,在寻址周期期间不提供数据脉冲,从而在预备周期期间不产生放电。在复位和维持周期期间,应用与图3相同的波形,并且因此不再给出其详细描述。
但是,在预备周期期间,发生不需要的维持放电,并且在面板上显示残留影像。更为具体的说,由用户在任意时间随机关闭PDP的电源,壁电荷留在放电单元中。具体地说,在关闭PDP的电源之前,这种壁电荷大部分留在显示亮的发光的放电单元中,并且在预备周期的维持周期期间,由这些剩余的电荷发生不需要的维持放电。因此,当关闭PDP的电源时,在显示亮的屏幕的放电单元的一部分中显示残留影像。
发明内容
因此,本发明的目的是至少解决现有技术的问题和缺点。
根据本发明的方面,提供了一种用于驱动具有扫描电极、寻址电极和维持电极的等离子显示面板的方法,该方法包括:数据驱动周期包含复位周期、寻址周期和维持周期,且在寻址周期期间提供数据脉冲到寻址电极;以及用于将提供驱动波形的电压升高到所需电压的预备周期位于数据驱动周期之前,在预备周期的寻址周期期间施加地电压到该寻址电极,从而分别在预备周期和数据驱动周期期间驱动等离子显示面板以便在每个放电单元中显示图像,其中在数据驱动周期的维持周期期间提供给扫描电极和维持电极的波形不同于在预备周期的维持周期期间提供给扫描电极和维持电极的波形,且在预备周期的维持周期期间不发生维持放电。
根据本发明,可以改进亮度、效率和对比度,并且实现高速驱动。

具体实施方式
下面将详细描述本发明的优选实施例,在附图中示出了其实例。
为了在每个放电单元中显示图像,在根据本发明的用于驱动PDP的方法中,该PDP在用于提供驱动波形的数据驱动周期期间和用于将用于提供驱动波形的电压升高到所需电压的预备周期期间被分别地驱动,在该情况下,在数据驱动周期的维持周期期间提供给电极的波形与在预备周期的维持周期期间提供给电极的波形不同。
在该方法中,在预备周期中包括的子场的维持周期期间,将地电压提供给包括在放电单元中的扫描电极和维持电极。
该方法包括步骤:在预备周期中包括的子场的维持周期期间,将第一维持脉冲提供给包括在放电单元中的扫描电极;以及将与第一维持脉冲同步的第二维持脉冲提供给放电单元中包括的维持电极。
在该方法中,在该预备周期中包括的子场的维持周期期间,在放电单元中包括的扫描电极或维持电极被浮接。
在该方法中,将维持脉冲提供给不浮接的其它电极。
在该方法中,在预备周期中包括的子场的维持周期期间,将在放电单元中包括的扫描电极和维持电极浮接。
在该方法中,在预备周期中包括的子场的维持周期期间,将地电压提供给包括在放电单元中的电极。
在该方法中,在预备周期中包括的子场的维持周期期间,将地电压施加到包括在放电单元中的电极1-3秒,优选的是2秒。
下面将参考图5到9详细描述本发明的优选实施例。
图5示出了根据本发明第一实施例的PDP的预备放电波形。
参考图5,根据用于复位放电单元的复位周期、用于选择放电单元的寻址周期和用于维持该单元的放电的维持周期单独地驱动预备放电波形。在如图3所示的数据驱动波形之前提供预备波形。
在复位周期期间,将上升沿波形在建立周期期间同时施加到所有扫描电极Y。通过这个上升沿波形,在整个屏幕的单元中发生弱放电,在单元中产生壁电荷。因为上升沿波形的电压没有升高到所需电压Vp,在放电单元中没有发生复位放电。在施加上升沿波形之后的撤除周期期间,将从低于上升沿波形的峰值电压的正极性电压下降的下降沿波形同时施加到扫描电极Y。
在寻址周期期间,将负极性的扫描脉冲Scan循序加到扫描电极Y,并且将地电压加到寻址电极X。因为没有足够的电压差值来产生在扫描电极Y和寻址电极X之间的寻址放电,就是说,因为没有提供数据脉冲,所以,不发生寻址放电。
同时,在撤除和寻址周期期间,将维持电压电平Vs的正极性DC电压提供给维持电极Z。
在维持周期期间,将地电压施加到扫描电极Y和维持电极Z。因此,如果将地电压加到扫描电极Y和维持电极Z,则在预备周期中包括的子场的维持周期期间不发生维持放电。就是说,因为在扫描电极Y和维持电极Z之间不发生放电,可以防止在预备周期期间显示残留影像。
实际上,在预备周期中应用如图5所示的多个子场,从而将电极Y、Z和X的电压升高到所需电压,例如,Vp、Vy、Vs或Va。之后,将如图3所示的数据驱动波形施加到扫描、维持和寻址电极以实现PDP的图像。如图3和5所示,预备放电波形和数据驱动波形彼此是不同的。
图6示出了根据本发明第二实施例的PDP的预备放电波形。
参考图6,根据用于复位放电单元的复位周期、用于选择放电单元的寻址周期和用于维持单元的放电的维持周期来单独地驱动预备放电波形。
复位周期和寻址周期具有和本发明的第一实施例相同的波形,并且因此省略其详细描述。
在维持周期期间,将同步的维持脉冲Sus,就是说相同幅度和相同时间周期的维持脉冲Sus加到扫描电极Y和维持电极Z。因此,如果将同步的维持脉冲Sus加到扫描电极Y和维持电极Z,因为在扫描电极Y和维持电极Z之间没有电压差值,在扫描电极Y和维持电极Z之间不发生维持放电。因此,可以防止在预备周期期间显示残留影像。
实际上,在预备周期中施加如图6所示的多个子场,从而将电极Y、Z和X的电压升高到所需电压,例如,Vp、Vy、Vs或Va。然后,将如图3所示的数据驱动波形施加到扫描、维持和寻址电极以实现PDP的图像。如图3和6所示,预备放电波形和数据驱动波形彼此不同。
图7示出了根据本发明第三实施例的PDP的预备放电波形。
参考图7,预备放电波形是根据用于复位放电单元的复位周期、用于选择放电单元的寻址周期和用于维持单元的放电的维持周期来单独地驱动的。
复位周期和寻址周期具有和本发明的第一实施例相同的波形,并且因此省略其详细描述。
在维持周期期间,将维持脉冲Sus加到扫描电极Y和维持电极Z的至少其中之一。将一半维持脉冲Sus感应到其它电极Y或Z。在这个情况下,维持脉冲Sus的一半被感应为浮接状态(floating state)。这样,在扫描电极Y和维持电极Z之间不发生维持放电。因此,可以防止在预备周期中显示残留影像。
实际上,在预备周期中施加如图7所示的多个子场,从而将电极Y、Z和X的电压升高到所需电压,例如,Vp、Vy、Vs或Va。然后,将如图3所示的数据驱动波形加到扫描、维持和寻址电极以实现PDP的图像。如图3和7所示,该预备放电波形和数据驱动波形彼此不同。
图8示出了根据本发明第四实施例的PDP的预备放电波形。
参考图8,该预备放电波形根据用于复位放电单元的复位周期、用于选择放电单元的寻址周期和用于维持单元的放电的维持周期来单独地驱动。
复位周期和寻址周期具有和本发明的第一实施例相同的波形,并且因此省略其详细描述。
在维持周期期间,将浮接状态的维持脉冲Sus加到扫描电极Y和维持电极Z。这样,在扫描电极Y和维持电极Z之间不发生维持放电。因此,在预备周期中可以防止显示残留影像。
实际上,在预备周期中应用如图8所示的多个子场,从而将电极Y、Z和X的电压升高到所需电压,例如,Vp、Vy、Vs或Va。然后,将如图3所示的数据驱动波形加到扫描、维持和寻址电极以实现PDP的图像。如图3和8所示,该预备放电波形和数据驱动波形彼此不同。
图9示出了根据本发明的第五实施例的PDP的预备放电波形。
参考图9,在用于提供驱动波形的数据驱动周期之前的预备周期期间,将地电压加到电极Y、Z和X,以在每个放电单元中显示图像。将该预备周期设置为1-3秒,优选地为2秒,从而将驱动波形的电压升高到所需电压,例如,Vp、Va、-Vy或Vs。换句话说,如图5的PDP的预备放电波形所示,在1-3秒,优选地为2秒的时间中,将地电压提供给扫描电极Y、维持电极Z和寻址电极X。在这个情况下,在预备放电周期期间,在PDP的先前驱动状态期间(也就是,在PDP的关闭操作期间)在放电单元中存在的电荷被消除。因此,不发生由先前的驱动状态引起的残留影像,并且可以改进PDP的显示质量。然后,在数据驱动周期期间,将所需电压提供给扫描电极Y、维持电极Z和寻址电极X,并且该PDP稳定地显示图像。
根据本发明的用于驱动PDP的方法在维持周期期间不产生维持放电,并且当接通PDP时防止显示由先前状态引起的残留影像,从而改进显示质量。另外,在提供数据驱动波形之前,该方法通过在1-3秒,优选地是2秒的时间中提供地电压给电极来消除在放电单元中的电荷,从而防止显示残留影像,并改进显示质量。
根据本发明,可以改进亮度、效率和对比度,并且实现高速驱动。
虽然参照具体的示例性实施例描述了本发明,但本发明并不由实施例限定而仅由权利要求限定,应该认可本领域的普通技术人员可以在不脱离本发明的范围和精神的情况下修改或变更实施例。
