Description

像素结构及其驱动方法、阵列基板和显示装置 技术领域
本发明涉及显示技术领域，尤其涉及一种像素结构及其驱动方法、阵列基板和显示装置。
背景技术
液晶显示器(LCD)包括不同颜色的子像素。不同颜色的子像素通常具有不同的电压-透过率曲线(如图8所示)，导致各自的饱和电压不同，从而不同颜色的子像素在不同灰阶下的亮度比例不同。
具体地，例如在平面转换型(IPS)LCD、超级高维场转换技术型(Advanced Super Dimension Switch，简称ADS)LCD之类的在像素结构中包含有狭缝电极的LCD中，在包括红色子像素、绿色子像素和蓝色子像素的情况下，红色子像素、绿色子像素和蓝色子像素在不同灰阶下的亮度比不同。例如，在某一低灰阶的时候红色子像素、绿色子像素和蓝色子像素的亮度比为1:5:0.2，因此从红色子像素、绿色子像素和蓝色子像素射出的光线混合得到的白色光的色坐标是(0.300,0.320)；在某一高灰阶的时候，红色子像素、绿色子像素和蓝色子像素的亮度比为1:6:0.2，即绿色子像素的亮度比例增大，因此从红色子像素、绿色子像素和蓝色子像素射出的光线混合得到的白色光的色坐标为(0.310，0.330)。因此，在用户观看过程中，显示图像中的白色部分有的偏蓝有的偏黄，导致色彩还原差，显示图像质量不理想。
发明内容
为了使得用户观看的显示图像的白色部分在任何灰阶下均具有适当、一致的色彩，从而实现理想的显示图像质量，通常需要在LCD输出显示图像之前对图像数据进行伽马(Gamma)校正。在现有技术中，分别采用不同的Gamma曲线对红色子像素、绿色子像素和蓝色子像素进行校正，以使得红色子像素、绿色子像素和蓝色子像素的亮度 比在高灰阶和低灰阶时一致。然而，本发明人发现，采用上述方法对LCD进行Gamma校正后，LCD的透过率降低，因此显示图像的亮度降低，从而LCD的显示图像质量仍然不理想。
针对现有技术中存在的上述技术问题，本发明提供了一种像素结构及其驱动方法、阵列基板和显示装置，其能够在不降低显示图像的亮度的情况下使得不同颜色的子像素的亮度比在不同灰阶处一致，从而提高LCD的显示图像质量。

具体实施方式
下面将结合附图对本发明的实施例进行清楚、完整地描述。显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明实施例提供了一种像素结构，具体地，该像素结构包括至少两种颜色的子像素，每个子像素包括相互绝缘设置的板状电极(如图2和图5中带阴影线的部分)和狭缝电极，不同颜色的子像素包括的狭缝电极被配置为具有不同的结构，以使得不同颜色的子像素的电压-透过率曲线一致。在此情况下，不同颜色的子像素的饱和电压相同，因此能够采用相同的伽马曲线对不同颜色的子像素进行伽马校正，从而保证了LCD的透过率在进行伽马校正后不会降低，使得显示图像的亮度较高，LCD显示的图像的质量较理想。
需要说明的是，上述板状电极可以为公共电极或者像素电极，相应地，上述狭缝电极可以为像素电极或者公共电极，只要保证靠近液晶分子的电极为狭缝电极即可。本发明实施例中优选板状电极为公共电极，狭缝电极为像素电极。
具体地，上述“不同颜色的子像素包括的狭缝电极被配置为具有不同的结构”可以是不同颜色的子像素包括的狭缝电极的电极的宽度、狭缝的宽度和狭缝与子像素的排列方向之间的夹角之中的至少一个不同。在一个示例中，不同颜色的子像素包括的狭缝电极的狭缝与子像素的排列方向之间的夹角被布置为相同，并且不同颜色的子像素 包括的狭缝电极的电极的宽度和狭缝的宽度之和布置为相同，然而不同颜色的子像素包括的狭缝电极的电极/狭缝的宽度不同。在另一个示例中，不同颜色的子像素包括的狭缝电极的狭缝与子像素的排列方向之间的夹角被布置为相同，不同颜色的子像素包括的狭缝电极的电极的宽度和狭缝的宽度之和布置为不同，并且不同颜色的子像素包括的狭缝电极的电极的宽度和狭缝的宽度均不同。在又一个示例中，不同颜色的子像素包括的狭缝电极的狭缝与子像素的排列方向之间的夹角被布置为不同，并且不同颜色的子像素包括的狭缝电极的电极的宽度和狭缝的宽度中的任一个相同或者两者均不同。显然，本发明不限于这些示例。
下面以像素结构包括红色、绿色和蓝色子像素的情况为例，结合附图详细地描述本发明的优选实施例。
图1为根据本发明一个实施例的像素结构的平面示意图。如图1所示，像素结构包括红色子像素1、绿色子像素2和蓝色子像素3。其中，红色子像素1包括第一狭缝电极11，绿色子像素2包括第二狭缝电极21，蓝色子像素3包括第三狭缝电极31。
图2为图1中的不同颜色的子像素沿A-A’方向的截面示意图。如图1和图2所示，第一狭缝电极11、第二狭缝电极21和第三狭缝电极31的狭缝与子像素的排列方向之间的夹角相同，第一狭缝电极11、第二狭缝电极21和第三狭缝电极31中的每一个的电极的宽度(即每个狭缝电极中的单个电极的宽度)与狭缝的宽度(即每个狭缝电极中的单个狭缝的宽度)之和相同(W1+S1＝W2+S2＝W3+S3)，且第一狭缝电极11、第二狭缝电极21和第三狭缝电极31的电极的宽度和狭缝的宽度均不同(W1≠W2≠W3，且S1≠S2≠S3)，以使得红色子像素1、绿色子像素2和蓝色子像素3的电压-透过率曲线一致。此时，红色子像素1、绿色子像素2和蓝色子像素3的电压-透过率曲线如图3所示。
现有技术中的红色子像素、绿色子像素和蓝色子像素的电压-透过率曲线如图8所示。由图8可以看出，随着电压的增大，红色子像素的透过率的增幅最大，蓝色子像素的透过率的增幅最小。因此，在 本发明的一个优选实施例中，将第一狭缝电极11、第二狭缝电极21和第三狭缝电极31的电极的宽度配置为逐渐增大，且将第一狭缝电极11、第二狭缝电极21和第三狭缝电极31的狭缝的宽度配置为逐渐减小，以使得红色子像素1、绿色子像素2和蓝色子像素3的电压-透过率曲线一致(如图3所示)。
在一个具体示例中，红色子像素1、绿色子像素2和蓝色子像素3中每一个设置为具有26微米的宽度和78微米的长度，第一狭缝电极11、第二狭缝电极21和第三狭缝电极31中的每一个的电极的宽度与狭缝的宽度之和设置为6.2微米。
第一狭缝电极11的电极的宽度W1为1.8微米，第一狭缝电极11的狭缝的宽度S1为4.4微米。
第二狭缝电极21的电极的宽度W2为2.1微米，第二狭缝电极21的狭缝的宽度S2为4.1微米。

需要说明的是，本实施例中的红色子像素1、绿色子像素2和蓝色子像素3的尺寸并不局限于此，同时第一狭缝电极11、第二狭缝电极21和第三狭缝电极31的结构并不局限于以上所述的具体尺寸。当红色子像素1、绿色子像素2和蓝色子像素3的尺寸改变时，第一狭缝电极11、第二狭缝电极21和第三狭缝电极31的结构也应相应的改变，在此不再进行赘述。
图4为根据本发明另一实施例的像素结构的平面示意图。图5为图4中的不同颜色的子像素沿B-B’方向的截面示意图。如图4和图5所示，第一狭缝电极11、第二狭缝电极21和第三狭缝电极31的狭缝与子像素的排列方向之间的夹角相同，第一狭缝电极11、第二狭缝电极21和第三狭缝电极31的电极的宽度与狭缝的宽度之和不同(W1+S1≠W2+S2≠W3+S3)，且第一狭缝电极11、第二狭缝电极21和第三狭缝电极31的电极的宽度和狭缝的宽度均不同(W1≠W2≠W3，且S1≠S2≠S3)，以使得红色子像素1、绿色子像素2和蓝色子像素3的电压-透过率曲线一致。此时，红色子像素1、绿色子像素2和蓝 色子像素3的电压-透过率曲线如图6所示。
在一个具体示例中，红色子像素1、绿色子像素2和蓝色子像素3中的每一个设置为具有26微米的宽度和78微米的长度。
第一狭缝电极11的电极的宽度与狭缝的宽度之和为5.1微米，第一狭缝电极11的电极的宽度W1为2.1微米，第一狭缝电极11的狭缝的宽度S1为3.0微米。

第三狭缝电极31的电极的宽度与狭缝的宽度之和为6.2，第三狭缝电极31的电极的宽度W3为2.8微米，第三狭缝电极31的狭缝的宽度S3为3.4微米。
需要说明的是，本实施例中的红色子像素1、绿色子像素2和蓝色子像素3的尺寸并不局限于此，同时第一狭缝电极11、第二狭缝电极21和第三狭缝电极31的结构并不局限于以上所述的具体尺寸。当红色子像素1、绿色子像素2和蓝色子像素3的尺寸改变时，第一狭缝电极11、第二狭缝电极21和第三狭缝电极31的结构也相应地改变，在此不再进行赘述。
尽管上文以包括红色、绿色和蓝色子像素的像素结构为例描述了本发明的优选实施例，然而可以想到的是，本发明不限于上述示例，而是可以应用于包括其它颜色的子像素的像素结构。例如，像素结构可以包括C(青色)、M(品红)、Y(黄色)和G(绿色)四种颜色的子像素，或者可以包括R(红色)、G(绿色)、B(蓝色)和E(翠绿色)四种颜色的子像素。
本发明实施例提供了一种像素结构，该像素结构包括至少两种颜色的子像素，每个所述子像素包括相互绝缘设置的板状电极和狭缝电极，不同颜色的所述子像素包括的狭缝电极配置为具有不同的结构，从而使得不同颜色的所述子像素的电压-透过率曲线一致。因此，不同颜色的所述子像素的饱和电压相同，从而能够采用相同的伽马曲线对不同颜色的子像素进行伽马校正。由此保证了LCD的透过率在进 行伽马校正后不会降低，使得显示图像的亮度较高，LCD显示的图像的质量较理想。
此外，本发明实施例还提供了一种阵列基板，该阵列基板包括根据本发明实施例的像素结构。
