Description
本申请要求2017年08月03日递交的发明名称为“液晶显示面板及具有液晶显示面板的液晶显示装置”的申请号为201710654355.6的在先申请优先权，上述在先申请的内容以引入的方式并入本文本中。
本发明涉及液晶显示技术领域，尤其涉及一种液晶显示面板及一种具有该液晶显示面板的液晶显示装置。
在液晶显示面板中，垂直配向(vertical alignment，VA)显示模式以其宽视野角、高对比度和无需摩擦配相等优势，成为大尺寸液晶显示装置的常见显示模式。然而，现有的VA显示模式下的液晶显示装置中通常存在以下两个问题：(1)受电压耦合(Feed through)的影响；(2)大视角观看时存在色偏。针对问题(1)，主要的解决手段为：增大存储电容(Cst)与共电极电压补偿等。通过增大存储电容可以减小电压耦合含量，但是现有技术中，存储电容通常会受到开口率等条件的限制而不能做的过大。此外，上述的共电极电压补偿的方式并不能针对所有灰阶的电压进行补偿，其原因是不同灰阶下液晶电容(Clc)的电容值存在明显差异，不同灰阶下正负电压的对称中心都会不同程度的偏离共电极电压(CFcom)，这将使得正帧时施加到液晶电容上的电位差Vlc与负帧时施加到液晶电容上的电位差Vlc的大小不一致，造成显示亮度存在一定差异而在画面品质上产生颗粒感。
针对问题(2)，通常采用特定的驱动方式来解决大视角下存在色偏的问题。请参照图1，其为现有LCD显示装置中的驱动方式。在该种驱动方式中，在相邻四行四列即4*4个像素单元中，左上的4个像素单元组成的显示单元10均为正(+)、右上4个像素单元组成的显示单元20均为负(-)、左下的4个像素单元组成的显示单元30均为-、右下的4个像素单元组成的显示单元40均为+。在该种驱动方式下，相邻的红色(R)像素单元、绿色(G)像素单元
或者蓝色(B)像素单元的极性均按照下述方式进行反转+、-、-、+或者-、-、+、+。也就是说，现有的驱动方式中，每一行中相同颜色的像素单元以两个像素单元作为周期进行极性的反转，例如，每一行中相邻的两个红色像素单元极性为+，与之相邻的另两个红色像素单元的极性为-，如此不断重复。然而，当相邻的两个或者多个同颜色的像素单元的极性相同时，不同灰阶下正负电压的对称中心都会不同程度的偏离共电极电压，仍会造成造液晶显示器的显示亮度存在一定差异，而且画面品质上容易因亮度不均产生颗粒感，影响观看效果。可见，现有的液晶显示面板中，其驱动方法虽然可以解决大视角色偏的问题，但是却无法弱化电压耦合造成显示画面上的颗粒感。

本发明实施例提供了一种液晶显示面板以及具有液晶显示面板的液晶显示装置，其不仅可以解决大视角观看时存在的色偏问题，还可以弱化电压耦合所造成的画面颗粒感，从而提升显示效果。以下分别进行详细说明。
请参阅图2，图2为根据本实施例的液晶显示装置200的结构示意图。该液晶显示装置200包括液晶显示面板210、扫描驱动单元220、数据驱动单元230，以及时序控制单元240。
所述扫描驱动单元220与数据驱动单元230分别电连接至液晶显示面板210。时序控制单元240电连接至扫描驱动单元220和数据驱动单元230，用以控制扫描驱动单元220扫描所述液晶显示面板210，并控制所述数据驱动单元230驱动液晶显示面板210以显示图像。
请参阅图2，本发明的液晶显示面板210包括多条数据线(图未标)、多条扫描线(图未标)和由像素单元212组成的像素单元阵列，所述数据线连接至所述数据驱动单元230以及所述像素单元阵列中的一列像素单元，用以在数据驱动单元230的控制下对相连接的所述像素单元提供数据信号，所述扫描线连接至所述扫描驱动单元220以及所述像素单元阵列中的一行像素单元，用以在扫描驱动单元220的控制下对相连接的所述像素单元提供扫描信号，所述像素单元阵列由红、绿、蓝三种颜色的像素单元212沿着行方向依次重复排列形成，并且所述像素单元阵列中每相邻的两行像素单元形成一个像素单元组，每一像素单元组中位于同一列的两个像素单元212的极性相同，而相邻的两个像素单元组中位于同一列相邻的两个像素单元212的极性相反，因此可解决大视角观看时存在的色偏问题。例如，在图2中，为了便于说明，在像素单元阵列中相邻的两行像素单元定义为第一像素单元组213，将像素单元阵列中另外相邻的两行像素单元定义为第二像素单元组214，该第二像素单元组214与所述第一像素单元组213相邻。可以理解的是，在本实施例中，所述像素单元阵列还包括第三像素单元组、第四像素单元组、第六像素单元组等，在此并不对其数量进行具体限制。为便于描述，本实施例以第一像素单元组213与第二像素单元组214为例加以说明。
所述第一像素单元组213中位于第一列的两个像素单元212的极性都为正(+)，第二像素单元组214中位于第一列的两个像素单元212的极性相同，并且与第一像素单元组213中第一列的两个像素单元212的极性相反，极性为负(-)；第一像素单元组213中第二列的两个像素单元212的极性都为正(+)，第二像素单元组214中第二列的两个像素单元212的极性相同，并且与第一像素单元组213中第二列的两个像素单元212的极性相反，极性为负(-)；第一像素单元组213中第三列的两个像素单元212的极性都为负(-)，第二像素单元组214中第三列的两个像素单元212的极性相同，并且与第一像素单元组213中第三列的两个像素单元212的极性相反，极性为正(+)。另外，同一行中的像素单元以12个像素单元212作为一个周期，同一周期内相邻的红色像素单元的极性相反以及相邻的蓝色像素单元的极性相反，以尽可能的弱化红色像素单元与蓝色像素单元受电压耦合所造成显示画面上的颗粒感。
请一并参照图3，图3为本发明第一实施方式的液晶显示面板210的结构示意图。在本发明第一实施例中，以4*12的像素单元阵列(包含第一像素单元组213与第二像素单元组214、每个像素单元组包括2*12个像素单元)、12条数据线、4条扫描线为例对本实施例的显示面板进行说明。
在本发明实施方式中，4个红色像素单元、4个绿色像素单元与4个蓝色像素单元按照红(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像素单元，每一条扫描线连接至位于同一行的像素单元，并且所述扫描线连接至所述扫描驱动单元220(如图1所示)，所述数据线连接至所述数据驱动单元230(如图1所示)，所述扫描线在扫描驱动单元220的驱动下输出扫描信号至相连接的每一所述像素单元，所述数据线在所述数据驱动单元230的驱动下输出数据信号至与之相连接的每一所述像素单元，从而在位于同一列像素单元中，处于同一像素单元组(第一像素单元组213或者第二像素单元组214)内的像素单元的极性相同，并且与相邻像素单元组(第二像素单元组214或者第一像素单元组213)中的像素单元的极性相反。此外，其中一像素单元组(例如第一行与第二行像素单元组成的第一像素单元组213)中每行的12个像素单元的极性依次按照如下方式反转：正、正、负、负、正、正、正、负、负、负、负、正；相邻的像素单元组(例如第三行与第四行像素单元组成的第二像素单元组214)中每行的12个像素单元的极性依次按照如下方式反转：负、负、正、正、负、负、负、正、正、正、负。
在本发明实施方式的液晶显示面板210中，所述像素单元阵列中每两行像素单元作为一个像素单元组进行极性反转，可解决大视角观看时存在的色偏问题。此外，每一行的像素单元中相邻的红色像素单元之间的极性交替变化，相邻的蓝色像素单元之间的极性也交替变化。例如，4*12像素单元阵列中，第一像素单元组213中每行的红色像素单元的极性依次如下：正(+)、负(-)、正(+)、负(-)，蓝色像素单元的极性依次如下：负(-)、正(+)、负(-)、正(+)，第二像素单元组214中每行的红色像素单元的极性依次如下：负(-)、正(+)、负(-)、正(+)，蓝色像素单元的极性依次如下：正(+)、负(-)、正(+)、负(-)。该种极性交替变换的方式可大大的弱化像素单元由于受电压反馈可能造成的颗粒感。具体原理如下：假设红色像素单元在极性为+时由于
受到电压耦合的影响而导致显示画面具有颗粒感，此时，若能将造成画面颗粒感的极性为+的红色像素单元均匀分布在像素单元阵列中，即将极性为+的红色像素单元与极性为-的红色像素单元交替设置，显然可削弱红色像素单元受电压耦合影响所产生的颗粒感；而若将造成画面颗粒感的极性为+的多个红色像素单元集中分布在像素单元阵列中，即将极性为+的两个或者多个红色像素单元相邻设置，此时相当于在显示画面上将多个颗粒聚集到一处，显然无法弱化红色像素单元受电压耦合影响所产生的颗粒感。
在本发明实施方式的液晶显示面板210中，相邻的绿色像素单元的极性并非是交替变化的，而是以两个绿色像素单元作为周期进行极性反转的，例如，4*12像素单元阵列中，第一像素单元组213中每行的绿色像素单元的极性依次如下：正(+)、正(+)、负(-)、负(-)，第二像素单元组214中每行的绿色像素单元的极性依次如下：负(-)、负(-)、正(+)、正(+)。该种极性反转方式虽然无法弱化绿色像素单元受电压耦合影响而产生的颗粒感，但是由于人眼对高灰阶的颜色(例如绿色)中存在的亮度差不敏感，而对低灰阶颜色(例如红色、蓝色)中存在的亮度差较为敏感，因此，虽然本实施例的显示面板中未能削弱绿色像素单元可能造成的颗粒感，但是由于已经大大地消弱了由红色像素单元与蓝色像素单元造成的颗粒感，即可大大的消除显示画面中由于电压耦合所造成的颗粒感。
在本实施方式的液晶显示面板210，不仅能解决大视角色偏的问题，还通过使每行相邻的红色像素单元以及相邻的蓝色像素单元的极性交替变化，从而削弱红色像素单元以及蓝色像素单元由于受电压耦合影响而在画面上产生的颗粒感，而由于人眼只对低灰阶颜色的像素单元(红色像素单元与蓝色像素单元)产生的颗粒感较为敏感，因此，只要削弱了红色像素单元与蓝色像素单元产生的颗粒感，即可削弱整个显示画面上产生的颗粒感，提升了液晶显示面板整体的显示效果。
参照图4，图4为本发明第二实施方式的液晶显示面板210的结构示意图。本实施方式的液晶显示面板210与第一实施例的液晶显示面板210相似，其不同之处在于：像素单元阵列中的像素单元的极性反转方式不同。具体的，以4*12的像素单元阵列(包含第一像素单元组213与第二像素单元组214、每个
像素单元组包括2*12个像素单元)为例，其中一像素单元组(例如第一行与第二行像素单元组成的第一像素单元组213)中每行的12个像素单元的极性依次按照如下方式反转：正、正、正、负、正、负、正、负、正、负、负、负(即，+、+、+、-、+、-、+、-、+、-、-、-)；相邻的另一个像素单元组(例如第三行与第四行像素单元所组成的第二像素单元组214)中每行的12个像素单元的极性依次按照如下方式反转：负、负、负、正、负、正、负、正、负、正、正、正(即，-、-、-、+、-、+、-、+、-、+、+、+)。
在本发明实施方式的液晶显示面板210中，所述像素单元阵列中每两行像素单元作为一个像素单元组进行极性反转，可解决大视角观看时存在的色偏问题。此外，每一行的像素单元中相邻的红色像素单元之间的极性交替变化，相邻的蓝色像素单元之间的极性也交替变化。例如，4*12像素单元阵列中，第一像素单元组213中每行的红色像素单元的极性依次如下：正(+)、负(-)、正(+)、负(-)，蓝色像素单元的极性依次如下：正(+)、负(-)、正(+)、负(-)，第二像素单元组214中每行的红色像素单元的极性如下：负(-)、正(+)、负(-)、正(+)，蓝色像素单元的极性依次如下：正(+)、负(-)、正(+)、负(-)。该种极性交替变换的方式可大大的弱化像素单元由于受电压反馈可能造成的颗粒感。虽然每相邻的两个绿色像素单元的极性并非交替变化的，但是由于人员对高灰阶颜色像素单元(绿色像素单元)所造成的亮度差不敏感，而对低灰阶颜色像素单元(红色像素单元与蓝色像素单元)所造成的亮度差较为敏感，因此，本实施方式中削弱了红色像素单元与蓝色像素单元可能产生的颗粒感，即可大大的削弱显示画面中存在的颗粒感。
综上，在本实施方式的液晶显示装置以及液晶显示面板210，不仅能解决大视角色偏的问题，还通过使每行相邻的红色像素单元以及相邻的蓝色像素单元的极性交替变化，从而削弱红色像素单元以及蓝色像素单元由于受电压耦合影响而在画面上产生的颗粒感，即可削弱整个显示画面上产生的颗粒感，最终大大的提升了显示效果。
上述显示面板以及具有显示面板的液晶显示装置，其不仅可解决大视角观看下存在的色偏问题，还能尽可能的消除由于电压耦合影响所造成显示画面上存在的颗粒感，从而大大提高了液晶显示面板的显示效果。
