Description

一种具有新型像素设计的液晶显示面板
本申请要求于2017年10月17日提交中国专利局、申请号为201710966626.1、发明名称为“一种具有新型像素设计的液晶显示面板”的中国专利申请的优先权，上述专利的全部内容通过引用结合在本申请中。
技术领域
本发明涉及显示领域，特别涉及一种具有新型像素设计的液晶显示面板。
背景技术
现有市场上的液晶显示器大部分为背光型液晶显示器，其包括壳体、设于壳体内的液晶显示面板及设于壳体内的背光模组。液晶显示面板是液晶显示器的主要组件，但液晶显示面板本身不发光，需要借由背光模组提供的光源来正常显示影像。
通常液晶显示面板由两片玻璃基板贴合而成，且在两片玻璃基板之间灌入液晶，分别在两片玻璃基板的相对内侧设置像素电极、公共电极，通过通电与否来控制液晶分子改变方向，将背光模组的光线折射出来产生画面。
现有的LCD中，大视角下会发生严重的色偏(color washout)现象，这种状况在垂直配向(Vertical Alignment，VA)型的LCD中更为明显，VA模式液晶显示器由于在不同视野角下，液晶分子双折射率差异较大，所以色偏现象比较严重。现有技术已经通过采用多畴(multi domain)显示的像素设计来LCD改善大视角下色偏，例如，在一些例子中，需要将像素设置为主区(Main)像素电极和次区(Sub)像素电极，每一区分别包括多畴(如4畴)，分别通过不同的薄膜晶体管(Thin Film Transistor，TFT)来控制主区像素电极和次区像素电极，并分别给主区像素电极和次区像素电极提供不同的驱动电压，使主区像素电极和次区像素电极的液晶产生不同的转动行为，从而对大视角下的伽马(Gamma)特性进行混合补偿，来达到改善色偏的目的。
如图1所示，示出了现有的一种液晶显示面板，其中示出了设置于两条数据线1’之间的一个像素电极结构，其采用8畴显示的像素设计，其中主区像素电极30’和次区像素电极31’均为4畴，TFT单元2’和栅级线4’设置在主区像素电极30’和次区像素电极31’之间；从中可以看出，现有的这种结构中，一个像素电极一般需要至少三个TFT单元2’，其控制电路比较复杂，且会降低像素的开口率。

同时，在本发明实施例中，由于每一像素单元只需要采用一个薄膜晶体管和一条栅极线，从而使驱动电路更加简单，并提高了像素的开口率。
附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其它的附图。
图1是现有技术中一种像素结构的示意图；
图2是本发明提供的一种具有新型像素设计的液晶显示面板一个实施例的结构示意图；
图3是图2中像素单元的一个实施例的示意图；
图4是图2中像素单元的另一个实施例的示意图；
图5是图2中像素单元的又一个实施例的示意图；
图6是图2中像素单元的再一个实施例的示意图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚完整地描述，显然，所描述的实施例仅仅是本发明的一部分实施例，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的前提下所获得的所有其它实施例，都属于本发明保护的范围。
在此，还需要说明的是，为了避免因不必要的细节而模糊了本发明，在附图中仅仅示出了与根据本发明的方案密切相关的结构和/或处理步骤，而省略了与本发明关系不大的其他细节。
如图2所示，是本发明提供的一种具有新型像素设计的液晶显示面板的一个实施例的结构示意图。在该实施例中，该液晶显示面板至少包括：相对设置的第一基板1和第二基板2，在所述第一基板1和第二基板2之间设置有液晶层4，其中：
所述第一基板1正对所述第二基板2的一侧表面设有公共电极层6；
所述第二基板2一侧表面上设置有像素电极层5，其上设置有多条栅极线和多条数据线，所述多条栅极线和所述多条数据线限定出多个像素单元。
进一步地，请参照图3所示，其示出了本发明的液晶显示面板中一个像素单元的一个实施例的结构示意图。
可以理解的是，所述第二基板2设置有沿列方向排布的多条数据线51和沿行方向排布的多条栅极线50，相邻两条数据线51和相邻两条栅极线50共同限定出一个像素单元。在一个像素单元中，其包括相连接的主区像素电极30与次区像素电极31，所述像素单元中还包括有一薄膜晶体管(TFT)7，所述主区像素电极30与所述次区像素电极31均通过所述薄膜晶体管7获取显示信号。具体地，所述薄膜晶体管7包括栅极72、源极70和漏极71，所述栅极72连接一栅极线50，所述源极70连接一数据线51，所述漏极71连接所述主区像素电极30与次区像素电极31。
其中，所述主区像素电极30与所述次区像素电极31并列设置。所述主区像素电极30与所述次区像素电极31内均包括主干电极线和与所述主干电极线连接的支干电极线，所述主区像素电极30的主干电极线与所述次区像素电极31内的主干电极线连接。具体地，在所述主区像素电极30中包括将所述主区像素电极分隔成四个畴的竖向主干电极线300和横向主干电极线301，所述竖向主干电极线300和横向主干电极线301大致成“十”字设置，在每一个畴中均分别设置有多条平行的支干电极线302，其中，每一畴中的支干电极线均302至少与所述竖向主干电极线300和横向主干电极线302中一个相连接；同样，所述次区像素电极31也包括有竖向主干电极线310和横向主干电极线311，所述竖向主干电极线310和横向主干电极线311将所述次区像素电极31分成四个畴，每一畴中均设置有多条支干电极线312。其中，所述主区像素电极30的竖向主干电极线300与所述次区像素电极31内的竖向主干电极线310相连接。
在图3中，所述主区像素电极30整体呈“米”字图案，所述次区像素电极31也为“米”字图案，可以理解的是，在其他的例子中，也可以将所述次区像素电极31设置为其他形状，例如设置为面状或梳状。
在本发明中，需要将所述主区像素电极30的图案与次区像素电极31的图案设计成存在差别。
具体地，在本发明的一个实施例中，所述次区像素电极31中支干电极线的线宽线距比值(Line/Space，L/S)与所述主区像素电极30中支干电极线的线宽线距比值存在差别，在图中，所述次区像素电极31的支干电极线的线宽线距比值小于所述主区像素电极30的支干电极线的线宽线距比值。
可以理解的是，在该实施例中，通过将所述次区像素电极31中支干电极线的线宽线距比值设置小于所述主区像素电极30中支干电极线的线宽线距比值；从而在薄膜晶体管(TFT)53对像素电极进行驱动时，使主区像素电极30与公共电极6之间的电势差，与次区像素电极31与公共电极6之间的电势差存在差别；具体地，在该例子中，由于所述次区像素电极31中支干电极线的线宽线距比值小于所述主区像素电极30中支干电极线的线宽线距比值。可以理解的是，由于电极线的线宽更小或线距更大，从而使次区像 素电极31与公共电极6之间的电势差更小，同时此区域对应的电场强度更小，从而使次区像素电极对应的液晶的偏转角度小于主区像素电极对应的液晶的偏转角度，在液晶偏转角度较小的情形下，大视角下的亮度会较强，从而上述差别可以使液晶显示面板获得较大视角。同时，由于每一像素电极只需要一个薄膜晶体管和一条栅极线，就可以驱动主区像素电极和次区像素电极的液晶，获得不同的偏转角度，从而使驱动电路更加简单，并提高了像素的开口率。
可以理解的是，在其他的实施例中，也可以将次区像素电极31中支干电极线的线宽线距比值设置成大于所述主区像素电极30中支干电极线的线宽线距比值，基于上一段所描述的原理，同样也可以达至增加液晶显示面板的视角的目的。
进一步的，对于需要将所述主区像素电极的图案与次区像素电极的图案设计成存在差别。请参照图4所示，其示出了本发明提供的液晶显示面板中一个像素单元的又一个实施例的结构示意图。
在图4所示了的实施例中，将所述次区像素电极中支干电极线和所述次区像素电极中主干电极线之间的夹角与所述主区像素电极中支干电极线和所述主区像素电极中同一方向主干电极线之间的夹角大小设置成不同。
具体地，在所述图4中，所述主区像素电极30中支干电极线302和所述主区像素电极30中竖向主干电极线300之间的夹角(图中标示为b)大于或等于45°，所述次区像素电极31中支干电极线312和所述次区像素电极31中竖向主干电极线310之间的夹角(图中标示为a)小于45°。一般地，可以将上述夹角称为倾斜角，可以理解地，在次区像素电极中，减少该倾斜角可以减小次区像素电极所对应的液晶的方位角，从而可以改善液晶显示面板的视角。
同样，可以理解的是，在其他的实施例中，也可以将主区像素中支干电极线的倾斜角设置成小于45度，同时将次区像素中支干电极线的倾斜角设置成小于或等于45度；同样，在其他的实施例中，也可以将主区像素中支干电极线的倾斜角和次区像素中支干电极线的倾斜角设置成相同，例如都设置成45°。
请参照图5所示，其示出了一个像素电极的又一个实施例的结构示意图。在该实施例中，其与图3示出的结构的区别在于，在该实施例中，所述主区像素电极30与所述次区像素电极交错设置；所述次区像素电极进一步包括第一次区像素电极32以及第二次区像素电极33，所述第一次区像素电极32和所述第二次区像素电极33均包括两个畴，所述主区像素电极30仍包括四个畴，所述主区像素电极30设置于所述第一次区像素电极32以及所述第二次区像素电极33之间。具体地，在所述主区像素电极30中包括将所述主区像素电极分隔成四个畴的竖向主干电极线300和横向主干电极线301，在每一个畴中均分别设置有多条平行的支干电极线302。所述第一次区像素电极32以及所述第二次区像素电极33分别包括竖向主干电极线310和横向主干电极线311，在每一畴中均设置有多条支干电极线312。其中，所述主区像素电极30的竖向主干电极线300分别与所述第一次区像素电极32和第二次区像素电极32内的竖向主干电极线310相连接。该实施例的其他结构与图3中示出的相同，在此不进行赘述。
可以理解的是，对于图4的结构，同样可以将所述主区像素电极30中支干电极线302和竖向主干电极线300之间的夹角，与所述第一次区像素电极32(或第二次区像素电极33)中支干电极线312和竖向主干电极线310之间的夹角设置成相同或不同。
请参照图5所示，其示出了一个像素电极的再一个实施例的结构示意图。在该实施例中，其与图3示出的结构的区别在于，在该实施例中，所述主区像素电极30与所述次区像素电极31嵌套设置，所述次区像素电极31设置于所述主区像素电极30的中心位置。
具体地，其中，所述主区像素电极30与所述次区像素电极31内均包括主干电极线和与所述主干电极线连接的支干电极线，所述主区像素电极30的主干电极线与所述次区像素电极31内的主干电极线连接。具体地，所述次区像素电极31也包括有竖向主干电极线310和横向主干电极线311，所述竖向主干电极线310和横向主干电极线311将所述次区像素电极31分成四个畴，每一畴中均设置有多条支干电极线312。在所述主区像素电极30中，所述竖向主干电极线300、横向主干电极线301以及包围所述次区像素电极 31的框形电极线303形成了主干电极线，所述主干电极线将所述主区像素电极分隔成四个畴，在每一个畴中均分别设置有多条平行的支干电极线302，其中，每一畴中的支干电极线均302至少与所述竖向主干电极线300、横向主干电极线302或框形电极线303中一个相连接；同样，其中，所述主区像素电极30的竖向主干电极线300与所述次区像素电极31内的竖向主干电极线310相连接。该实施例的其他结构与图3中示出的相同，在此不进行赘述。
可以理解的是，对于图5的结构，同样可以将所述主区像素电极30中支干电极线302和竖向主干电极线300之间的夹角，与所述次区像素电极31中支干电极线312和竖向主干电极线310之间的夹角设置成相同或不同。

本发明实施例中，通过将每一像素单元中的像素电极分成主区像素电极与次区像素电极，并且通过将所述主区像素电极的图案与次区像素电极的图案设置成存在差别，例如将所述次区像素电极中支干电极线的线宽线距比值设置成与所述主区像素电极中支干电极线的线宽线距比值存在差别，或者将所述次区像素电极中支干电极线和所述次区像素电极中主干电极线之间的夹角与所述主区像素电极中支干电极线和所述主区像素电极中同一方向主干电极线之间的夹角大小设置成不同；从而在薄膜晶体管对像素电极进行驱动时，使主区像素电极与公共电极之间的电势差，与次区像素电极与公共电极之间的电势差存在差别；上述差别可以使其中一个区域对应的液晶的偏转角度小于另一个区域对应的液晶的偏转角度，从而可以使液晶显示面板获得较大视角。
在发明实施例中，通过所述次区像素电极中支干电极线与竖向主干电极线的夹角设置成与主区像素电极中支干电极线与竖向主干电极线的夹角大小不同，可以减小部分像素电极所对应的液晶的方位角，从而可以改善液晶显示面板的视角；
