Description

液晶显示面板 技术领域
本申请涉及显示技术领域，尤其涉及一种液晶显示面板。
 背景技术
在传统的像素结构中，通常在数据线上方设置黑矩阵（Black matrix，BM）进行遮光，以提高显示面板的对比度。但在制备过程中，往往由于上下基板对位精度存在偏差，导致黑矩阵发生左右移动，进而导致数据线漏光。现有的像素结构采用DBS（Data line BM Less）技术，去除数据线上方的黑矩阵，在数据线上方设置DBS电极，并使得DBS电极的电位与彩膜基板上的公共电极电位相同，使得数据线上方对应的液晶分子始终保持未偏转状态，进而起到遮光的作用，另外，DBS电极与数据线同位于阵列基板上，对准精度偏差较小，能够避免由于黑矩阵移动导致的漏光问题。

如图1所示，本申请实施例提供一种液晶显示面板100，包括相对设置的彩膜基板20和阵列基板10、以及夹设于所述彩膜基板20和阵列基板10之间的液晶层30。其中，所述阵列基板10包括多条数据线12和多个设置于所述数据线12上方的DBS电极。
所述DBS电极14的宽度大于所述数据线12的宽度，每一数据线12的上方对应设有一个所述DBS电极14。
如图2所示，相邻的所述DBS电极14通过桥接线16连接，所述DBS电极14与彩膜基板20上的公共电极23的电位相同，从而使得数据线12对应处的液晶分子始终保持未偏转状态，从而起到遮光作用。
但是由于现有结构中，在厚度方向上，DBS电极完全与数据线重合，导致数据线的寄生电容较大，限制了DBS电极在高频率、大尺寸面板中的应用，因此本申请实施例通过改变DBS电极的结构，在DBS电极14上增设狭缝状开口141以解决上述缺陷。
所述DBS电极14包括至少一个间隔设置的狭缝状开口141，所述狭缝状开口141能够减少DBS电极14与数据线12的重合面积，从而达到降低数据线12的寄生电容的效果。
由于所述DBS电极14上开设有所述狭缝状开口141，为了进一步增强遮光效果，可在所述彩膜基板20朝向所述阵列基板10的一侧设置黑矩阵22，且所述黑矩阵22覆盖与其对应的所述狭缝状开口141，从而弥补由于所述狭缝状开口141的存在导致的遮光不足。
所述彩膜基板20与所述阵列基板10对位时，由于对位精度存在偏差，所述黑矩阵可能发生左右移动，因此可将所述黑矩阵22的宽度设置为大于或等于所述数据线12的宽度。
如图3所示，进一步地，由于黑矩阵22的对位精度有限，至少一个所述狭缝状开口141在所述数据线12上的正投影可位于所述数据线12的延伸方向的中心线121上，使得所述狭缝状开口141处的漏光处于数据线的中心处，该部分的漏光由黑矩阵22遮盖，且即使黑矩阵22对位发生偏移，也能使得黑矩阵22覆盖所述狭缝状开口141。
所述数据线12与所述DBS电极14同处于阵列基板10上，对位精度偏差较小，因此，至少一个所述狭缝状开口141可间隔设置于所述DBS电极14的延伸方向的中心线上，通过在所述DBS电极14的中心处挖孔形成所述狭缝状开口141。
多个所述狭缝状开口141可等间距设置，相邻的两个所述狭缝状开口141之间的距离视实际的设计需要而定，这里不做限制。
相邻的两个所述狭缝状开口141之间的距离可为零，此时，所述DBS电极14上仅开设一个狭长的所述狭缝状开口141。
所述狭缝状开口141贯穿所述DBS电极14上下表面。
所述狭缝状开口141的延伸方向（长度方向）与所述DBS电极14的延伸方向相同，所述狭缝状开口141为封闭形状的开口，避免所述狭缝状开口141设置于所述DBS电极的边缘，从而保证所述DBS电极14边缘的遮光能力，以补偿所述黑矩阵22移动造成的漏光问题。
在本申请实施例中，所述狭缝状开口141为矩形，在其他实施例中，如图4所示，所述狭缝状开口141为椭圆形，还可为其他形状，如三角形、圆形、正方形等形状。
所述狭缝状开口141的宽度不能过宽，避免所述DBS边缘漏光，所述狭缝状开口141的具体尺寸视实际像素大小和所述数据线的宽度而定。
当所述狭缝状开口141为矩形时，所述狭缝状开口141的长度范围为5微米至20微米，所述狭缝状开口的宽度范围为2.5微米至数据线宽度的三分之一，具体地，在本实施例中，所述狭缝状开口长度可为10微米，宽度可为3微米。
当所述狭缝状开口141为三角形时，所述三角形的高度可与所述矩形的长度相同，宽度可与所述矩形的宽度相同。虽然三角形状的开口面积没有矩形的开口面积大，减小寄生电容的程度没有矩形明显，但对比度相对于矩形开口的对比度更高。
所述阵列基板10上还设置有像素电极15，所述DBS电极14可与所述像素电极15同层设置，可经过同一构图工艺形成所述像素电极15和所述DBS电极14。
相邻的所述DBS电极14可通过桥接线16连接，当所述DBS电极14与所述桥接线16异层设置时，所述桥接线16可通过过孔桥接两所述DBS电极14；当所述DBS电极与所述桥接线16同层设置时，所述桥接线16可直接连接两所述DBS电极。
在本实施例中，所述阵列基板10包括第一衬底基板11、设置于所述第一衬底基板11上的数据线12、与所述数据线12同层设置的源极和漏极（图中未示出）、设置于所述数据线12上的绝缘层13、以及同层设置且设置于所述绝缘层上的多个DBS电极14和像素电极15。所述阵列基板10还包括栅极、扫描线、有源层等，可参考现有技术，这里不再赘述。
当所述DBS电极14、所述桥接线16、以及所述像素电极15同层设置时，所述像素电极15可包括隔开的主像素电极和次像素电极，所述桥接线16设置于所述主像素电极和次像素电极之间。
所述扫描线设置于所述主像素电极和所述次像素电极之间，且所述主像素电极和所述次像素电极均与该行子像素对应的扫描线连接。
所述桥接线16沿着扫描线的边缘进行走线，从而降低信号线之间的信号干扰。
所述像素电极15、所述桥接线16、以及所述像素电极15可均为氧化铟锡材料。
所述彩膜基板20包括第二衬底基板21、设置于所述第二衬底基板21朝向所述阵列基板10一侧的黑矩阵22、以及设置于所述黑矩阵22之上的公共电极23。
所述阵列基板10可为COA（Color Filter On Array，彩色滤光片整合于阵列基板上）基板，所述阵列基板10还包括彩色虑光层（图中未示出），所述彩色虑光层设置于所述数据线12的上方。
通过在数据线12上方的DBS电极14上增设至少一个狭缝状开口141，且保留数据线12上方的黑矩阵22以对狭缝状开口141进行遮光，从而解决现有的像素结构中由于数据线与DBS电极始终保持重合，导致数据线的寄生电容较大的问题。本实施例通过模拟设计，相对于现有技术，在单个像素中数据线的寄生电容能够降低30%，有利于DBS电极在高频率、大尺寸显示面板中的应用。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
