Description

显示面板及其驱动方法 技术领域
本发明是有关于一种显示面板，特别是有关于一种使用极性反转驱动方式的显示面板。
 背景技术
随着科技的发展，显示面板的分辨率要求也相对提高，现有提高面板色度可视角的方法主要有两种，第一种方法为显示面板的创新性设计，例如：多象限垂直配向技术；第二种方法为对输入数据的预处理，即对子像素进行亮/暗（H/L）处理。相对于第一种方法的高成本要求，第二种方法可以在较低成本的情况下实现色度可视角的提高，但是驱动方式和数据映像之间的合理搭配是实现色度可视角的提高的关键。
请参照图1和图2，分别示出了两种现有的驱动方式，图1所示的第一种驱动方式所驱动的显示面板10的水平方向上的子像素110、111、112、113的极性分别设置为：正极性、负极性、负极性、正极性，在竖直方向上的子像素110、116、117、118的极性设置为：1+2行反转，数据映像为亮、暗(其中暗是以斜线标示)。图2所示的第二种驱动方式所驱动的显示面板20的水平方向上的子像素210、211、212、213的极性设置为：正极性、负极性、正极性、负极性，在竖直方向上的子像素210、216、217、218的极性设置为：列反转，数据映像为亮、亮、暗、暗(其中暗是以斜线标示)。
两种驱动方式均存在不同的显示缺陷，第一种驱动方式中的同一条数据线上的正、负极性的切换非常频繁，造成驱动器的负载增大，从而增加了功耗，容易产生亮暗线，而第二种驱动方式会造成数据信号经过处理后使颗粒感加重，并且会出现串音的问题，只适合在8k或者更高解析度的面板上使用，并不适用于4k面板。
此外，在液晶显示面板的数据走线、电极以及薄膜晶体管之间存在着大量的耦合电容，耦合电容会衍生出很多显示问题，例如：使像素电极上的电压亦产生一馈通电压，导致画面显示的亮度不均匀。
 技术问题
故，有必要提供一种显示面板，以解决现有技术所存在的问题。

请参照图3所示，本发明的一实施例的显示器30主要包括时序控制器301、源极驱动器302、栅极驱动器303、显示面板304以及公共电压输出驱动器305，时序控制器301将数据信号、亮度信号和极性控制信号发送到源极驱动器302，以及将扫瞄信号和输送信号发送到栅极驱动器303，源极驱动器302输出数据电压，公共电压输出驱动器305输出公共电压，数据电压以及公共电压的电压差(即驱动电压)驱动液晶分子转动完成显示，从而使显示面板304显示图像，当数据电压高于公共电压时，驱动电压的极性为正极性，反之，驱动电压的极性为负极性。
为方便图示说明本发明的实施例，图4A、图4B、图5A及图5B中的子像素的行的数量以4行为例，图4A、图4B、图5A及图5B中的子像素的列的数量以本发明的一实施例的最小单位(16列)来绘示，本发明的一实施例的显示面板可以包括16列以上的子像素以及任意数量的行的子像素。
请参照图4A和图4B，图4A和图4B分别是本发明的一实施例的显示面板40中的多个子像素(如子像素421至439等)在奇数帧和偶数帧时的极性排列的示意图。本发明的一实施例的显示面板40包含多条数据线401至404以及多个子像素(如子像素421至439等)，数据线401至404用于传送数据信号，子像素是显示面板40的基本显像单位，每个像素41包括三个子像素421、422、423。数据信号包括极性控制信号和亮度信号，子像素421至439根据极性控制信号呈现不同极性，子像素421至439根据亮度信号呈现不同亮度，在本发明的一实施例中，同一列的子像素(例如：子像素421、437、438、439)连接在同一条数据线401上。时序控制器(见图3的301)在显示面板40中的多个子像素(如子像素421至439等)上施加极性控制信号，使得多个子像素(如子像素421至439等)在奇数帧和偶数帧之间交替地进行正、负极性反转。
每个子像素(如子像素421至439等)的两端分别接收公共电压和数据线电压以进行充电，在本发明的一实施例中，公共电极的电压既可以选择彩色滤光片基板上的公共电极的电压值，也可以选择阵列基板上的公共电极的电压值。使得相应的驱动电路的设计更具灵活性。
多个子像素(如子像素421至439等)呈矩阵排列，每个子像素是选自于第一子像素、第二子像素以及第三子像素所组成的群组，每个像素41中的三个子像素421、422、423互相不同，并且按顺序排列。每个子像素(如子像素421至439等)各自对应于一种颜色，在本发明的一实施例中，第一子像素为红色子像素，第二子像素为绿色子像素，第三子像素为蓝色子像素。在本发明的一实施例中，6个红色子像素、5个绿色子像素与4个蓝色子像素按照红(R)、绿(G)、蓝(B)的顺序沿行方向重复排列形成。每一条数据线连接至位于同一列的子像素。在本发明的一实施例中，子像素421、424、427、430、433、436及其垂直方向上的子像素为第一子像素，例如：红色子像素，子像素422、425、428、431、434及其垂直方向上的子像素为第二子像素，例如：绿色子像素，子像素423、426、429、432、435及其垂直方向上的子像素为第三子像素，例如：绿色子像素。
请参照图4A和图4B，显示面板40中的所有子像素(如子像素421至439等)呈矩阵排列，形成N列子像素及M行子像素，其中N和M为整数，多个子像素被划分为第一区域410、第二区域411、第三区域412以及第四区域413，每个区域410至413包括以4×M矩阵排列的多个子像素；第一区域410和第四区域413中的第一行子像素的极性设置为第一极性排列，第二区域411和第三区域412中的第一行子像素的极性设置为第二极性排列；在第一极性排列中，如第一区域410中第一行的子像素421、422、423、424的极性排列所示，相邻的多个子像素的极性互相相反。第二极性排列与第一极性排列颠倒，如第二区域411中第一列的子像素425、426、427、428的极性排列所示。设置为正极性的子像素受正电压驱动，设置为负极性的子像素受负电压驱动。
在本发明的一实施例中，当显示面板具有N条数据线连接N列子像素和M行子像素时，N列子像素被划分为4K个区域群组，每个区域群组具有K个如图4A和图4B所示的区域(即第一区域410、第二区域411、第三区域412以及第四区域413)，每个区域410至413包括以4×M矩阵排列的多个子像素。例如：当解析度为4096×2160时，每一列子像素中具有4096×3个子像素，每一行子像素中具有2160个子像素，即N等于4096×3，M等于2160，则所述划分为768个区域群组，共3072个区域，即4K等于768，K等于3072，因此，每个区域群组中的每个区域具有以4×2160矩阵排列的多个子像素。
在本发明的一实施例中，第一极性排列依次为正极性、负极性、正极性、负极性，第二极性排列依次为负极性、正极性、负极性、正极性，每个区域中的同一列(例如：第一区域410中第一列的子像素421、437、438、439)上的多个子像素均具有相同的极性，每一列的子像素在偶数帧(例如：第二帧)时承载与奇数帧(例如：第一帧)相反的极性，如图4A和图4B，“+”表示具有相对于公共电压为正电压的子像素，“-”表示具有相对于公共电极电压为负电压的子像素，在极性控制信号的控制下，任意相邻的子像素极性相反，并且每一个子像素在任意相邻的两帧中的极性相反，设置在竖直方向上（即同一列）的子像素(例如：图4A的第1列的子像素421、437、438、439)的极性相同，解决了同一条数据线上正、负极性的切换非常频繁的问题，有效降低驱动器的负载，从而实现降低功耗的目的。
从图4A和图4B可看出，位于第一区域410的第4列子像素的极性与位于第二区域411的第5列子像素的极性相同，位于第三区域412的第12列子像素的极性与位于第四区域413的第13列子像素的极性相同，因此，第一区域410的公共电压和数据线电压之间的第一馈通电压与第二区域411中的公共电压和数据线电压之间的第二馈通电压互相抵消，第三区域412中的公共电压和数据线电压之间的第三馈通电压与第四区域413中的公共电压和数据线电压之间的第四馈通电压互相抵消，大大减少了在液晶显示面板的数据走线、电极以及薄膜晶体管之间存在的耦合电容，解决现在显示面板的画面显示的亮度不均匀、出现亮暗线的问题。
此外，由于每个子像素(如子像素421至439等)的极性在奇数帧和偶数帧时正负交替变换，因此，每个子像素(如子像素421至439等)的总体平均电压为0，不偏向某一极性，避免液晶长时间朝一个极性方向旋转而极化，并且防止液晶分子烧附而失去旋转能力和形成残像的问题。
请参照图5A和图5B所示，图5A和图5B分别是本发明的一实施例的显示面板50的所述多个子像素(如子像素521至539等)在奇数帧和偶数帧时的数据映像的示意图，相邻的多个子像素中的一个子像素的第一显示亮度大于另一个子像素的第二显示亮度。在本发明的实施例中，第一子像素521设置为亮度较高，在水平方向上，与第一子像素521相邻的第二子像素522设置为亮度较低，与第二子像素522相邻的第三子像素523设置为亮度较高，与第三子像素523相邻的第一子像素524设置为亮度较低，如此类推；在垂直方向上，与第一子像素521相邻的另一第一子像素537设置为亮度较低，与第一子像素537相邻的另一第一子像素538设置为亮度较高。
因此，本发明的一实施例中，将欲显示的亮度拆分成一亮一暗的亮度信号的组合，分别传送到相邻的两个代表同种颜色的子像素中，例如：欲显示的亮度所代表的灰阶值为100，通过将相邻的两个代表同种颜色的子像素(例如：子像素521和537，或是子像素521和524)中其中一个子像素(例如：子像素521)的灰阶值设置为120，另一个子像素(例如：子像素537或524)的灰阶值设置为80，由于所述两个子像素的平均值仍然为100，使得显示面板中的液晶排列更丰富，色度可视角更大，得到更高的解析度。
由于同一类型的子像素(如子像素521、524、527、530、533、536、537至539等)是以亮/暗间隔排列，因此能够避免当显示某一特定颜色时，其中代表一不需要的颜色的子像素因为被设置为较暗而成为肉眼可以轻易看出其间夹杂的黑色斑点，导致本来应该是纯净的颜色表面出现颗粒感和网纹的问题，本发明的子像素由于相邻的子像素中的液晶的取向更加丰富，因此，避免产生颗粒感，提高显示面板的色度可视角及分辨率。
图5A和图5B分别表示本案的一实施例中的子像数在奇数帧以及偶数帧时的数据映像，在本发明的一实施例中，子像素(如子像素521至539等)可以在接收到来自于时序控制器(见图3的301)的亮度信号后，将多个子像素(如子像素521至539等)的亮度排列切换至与原来显示的亮度排列相反的亮度排列，如图5A和图5B所示，“H”表示亮、亮度较高或灰阶值较高，“L”表示暗、亮度较低或灰阶值较低，在亮度控制信号的控制下，相邻的两个所述子像素中的一个所述子像素在偶数帧时的第一显示亮度大于在奇数帧时的第一原始亮度，另一个所述子像素在所述第二帧时的第二显示亮度小于在所述第一帧时的第二原始亮度。例如：相邻的两个子像素521和522：在奇数帧时，子像素521设置为亮(H)，而子像素522设置为暗(L)；在偶数帧时，子像素521设置为暗(L)，而子像素522设置为亮(H)。
图6的本发明的一实施例的显示面板的驱动方法的流程图，如图6所示，在本发明的一实施例中，还提供了一种显示面板的驱动方法：
S101：将多个子像素(如图4A和图4B的子像素421至439) 按矩阵排列，形成N列子像素及M行子像素，划分为第一区域410、第二区域411、第三区域412以及第四区域413，每个所述区域包括4×M个所述子像素；
S102：时序控制器 (见图3的301)传送极性控制信号到所述多个子像素(如子像素421至439)；
S103：根据极性控制信号以第一极性排列驱动所述第一区域410和所述第四区域413中的所述多个子像素，以第二极性排列驱动所述第二区域411和所述第三区域412；在所述第一极性排列中，同一行上的相邻的所述多个子像素(如子像素421、422)的极性互相相反，所述第二极性排列与第一极性排列颠倒，每个所述区域中的同一列上的所述多个子像素(如子像素421、437、438、439)均具有相同的极性，每个所述子像素(如子像素421、437、438、439)在第二帧时承载与第一帧相反的极性。
S104：时序控制器301传送数据信号到所述多个子像素(如子像素421至439)；以及
S105：改变所述子像素(如子像素421至439)的亮度，使得相邻的所述多个子像素中的一个(如图5A和图5B的521)所述子像素的第一显示亮度大于另一个所述子像素(如图5A和图5B的522、537)的第二显示亮度。
本发明的显示面板及其驱动方法解决了同一条数据线上正、负极性的切换非常频繁的问题，有效降低驱动器的负载，从而实现降低功耗的目的，也通过使不同区域的公共电压和数据线电压之间的第一馈通电压与第二区域中的公共电压和数据线电压之间的第二馈通电压互相抵消，大大减少了在液晶显示面板的数据走线、电极以及薄膜晶体管之间存在的耦合电容，解决现在显示面板的画面显示的亮度不均匀、出现亮暗线的问题。此外，本发明的显示面板及其驱动方法使液晶的取向更加丰富，避免了颗粒感和网纹的出现，提高显示面板的色度可视角及分辨率。
本发明已由上述相关实施例加以描述，然而上述实施例仅为实施本发明的范例。必需指出的是，已公开的实施例并未限制本发明的范围。相反地，包含于权利要求书的精神及范围的修改及均等设置均包括于本发明的范围内。
