请参阅图1至图4。本申请第一实施例提供的液晶显示面板100包括相对设置的阵列基板11和彩膜基板12以及设置在阵列基板11和彩膜基板12之间的液晶13。阵列基板11包括公共电极线14、栅极15和透明电极层16。透明电极层16设置在公共电极线14和栅极15上。在平行于阵列基板11所在平面的方向上,公共电极线14和栅极15之间具有间隔区域AA’。其中,透明电极层16包括遮光电极161和像素电极162。遮光电极161和像素电极162电性连接,且遮光电极161覆盖间隔区域AA’。
由此,本申请第一实施例提供的液晶显示面板100通过用遮光电极161覆盖栅极15和公共电极线14之间的间隔区域AA’,并将遮光电极161与像素电极162电性连接,使得遮光电极161和像素电极162具有相同电位,进而在暗态时,位于间隔区域AA’的液晶13与像素开口区的液晶13电场保持一致,避免了该处的液晶13因受到栅极15附近电场的影响而发生异常偏转。当面板受到按压或挤压时,即使阵列基板11和彩膜基板12发生偏移而出现对位异常,由于偏移区域的液晶13可以保持暗态不透光状态,从而有效防止了偏移区域发生漏光现象,提升了液晶显示面板的画质。
请继续参阅图1至图3。液晶显示面板100包括多个阵列排布的子像素单元100a。具体的,子像素单元100a包括主像素电极区和次像素电极区,以及设置在主像素电极区和次像素电极区之间的薄膜晶体管驱动区(图中未标识)。遮光电极161位于薄膜晶体管驱动区。
如图4所示,具体的,阵列基板11还包括第一基板11a。第一基板11a可以为玻璃基板。彩膜基板12包括依次设置的第二基板12a和黑色矩阵121。黑色矩阵121设置在彩膜基板12靠近阵列基板11的一侧。此外,阵列基板11还包括源极、漏极、半导体层和层间绝缘层等膜层结构(图中未示出),彩膜基板12还包括彩色滤光层和公共电极层等膜层结构(图中未示出),阵列基板11和彩膜基板12的具体结构均可以参照现有技术,在此不再赘述。
请继续参阅图3和图4。在本申请第一实施例中,公共电极线14和栅极15同层设置。栅极15位于相邻的公共电极线14之间。在一些实施例中,公共电极线14和栅极15也可以为异层设置,本申请对此不作限定。
在本申请第一实施例中,遮光电极161部分覆盖间隔区域AA’。具体的,在平行于阵列基板11所在平面的方向上,遮光电极161和栅极15之间具有预设水平距离b。
在本申请第一实施例中,预设水平距离b大于零。预设水平距离b的具体数值根据实际应用情况进行设定,本申请对此不作限定。
上述设置通过使得遮光电极161和栅极15之间留有一定空间,可以避免遮光电极161与栅极15之间产生寄生电容。同时,上述设置还可以减小阵列基板11和彩膜基板12之间的对位精度误差,避免因阵列基板11和彩膜基板12发生偏移而产生色偏问题。
进一步的,在本申请实施例中,遮光电极161于阵列基板100所在平面的正投影和公共电极14于阵列基板100所在平面的正投影部分重叠,该设置可以使得遮光电极161与公共电极14的重叠部分产生存储电容。
在一些实施例中,遮光电极161完全覆盖间隔区域AA’。具体的,遮光电极161恰好完全覆盖间隔区域AA’,或者,遮光电极161于阵列基板所在平面的正投影和栅极14于阵列基板11所在平面的正投影部分重叠。上述设置可以完全遮蔽栅极15附近的漏光区域,进而最大程度地降低该区域液晶13发生异常偏转的几率。
可选的,遮光电极161的图案为条形、方形或其他不规则形状。遮光电极161的具体图案可以根据实际情况进行设定,本申请对此不作限定。
在本申请第一实施例中,遮光电极161的图案为条形。
在本申请第一实施例中,遮光电极161和像素电极162同层设置。另外,在一些实施例中,遮光电极161和像素电极162也可以为异层设置,在此不再赘述。
进一步的,遮光电极161通过过孔161a与像素电极162电性连接,如图3所示。该设置使得遮光电极161与像素电极162具有相同的电位,进而当面板处于暗态时,间隔区域AA’的液晶13在遮光电极161与彩膜基板12上公共电极形成的电场作用下保持暗态不透光状态,从而避免了漏光现象的发生。
具体的,像素电极162通过过孔161a与阵列基板11中的漏极电性连接,过孔161a内填充有透明导电材料,遮光电极161即可通过过孔161a与像素电极162电性连接。可以理解的是,遮光电极161也可以通过其他方式与像素电极162电性连接,本实施例不能理解为对本申请的限制。
请继续参阅图3和图4。在本申请第一实施例中,遮光电极161与像素电极162一体成型。该设置可以节省光罩数量,简化工艺制程,从而有利于节约工艺成本。另外,在一些实施例中,遮光电极161与像素电极162还可以为分体结构,在此不再赘述。
进一步的,像素电极162包括主像素电极1621和次像素电极1622。主像素电极1621和次像素电极1622并排且间隔设置。遮光电极161包括第一遮光电极1611和第二遮光电极1612。第一遮光电极1611与主像素电极1621电性连接。第二遮光电极1612与次像素电极1622电性连接。
具体的,第一遮光电极1611通过主电极区上的过孔1611a与主像素电极1621电性连接。第一遮光电极1611和主像素电极1621一体成型。第二遮光电极1612通过次电极区上的过孔1612a与次像素电极1622电性连接。第二遮光电极1612和次像素电极1622一体成型。
进一步的,第一遮光电极1611于阵列基板11所在平面的正投影为第一投影。第二遮光电极1612于阵列基板11所在平面的正投影为第二投影。第一投影和第二投影关于栅极15于阵列基板11所在平面的正投影对称设置。该设置通过将第一遮光电极1611与第二遮光电极1612对称设置,保证了薄膜晶体管区域两侧的电场相同,降低了因液晶13不正常偏转而导致暗纹产生的可能性。
本申请第一实施例提供的液晶显示面板100通过用遮光电极161覆盖栅极15和公共电极线14之间的间隔区域AA’,并将遮光电极161与像素电极162电性连接,使得遮光电极161和像素电极162具有相同电位,进而在暗态时,位于间隔区域AA’的液晶13与像素开口区的液晶13电场保持一致,避免了该处的液晶13因受到栅极15附近电场的影响而发生异常偏转。当面板受到按压或挤压时,即使阵列基板11和彩膜基板12发生偏移而出现对位异常,由于偏移区域的液晶13可以保持暗态不透光状态,从而有效防止了偏移区域发生漏光现象,提升了液晶显示面板的画质。
请参阅图5和图6。图5为本申请第二实施例提供的液晶显示面板的平面结构示意图;图6为图5中沿PP’线的剖面结构示意图。
本申请第二实施例提供的液晶显示面板100与第一实施例的不同之处在于:在垂直于阵列基板11所在平面的方向上,黑色矩阵121和像素电极162错开设置。
具体的,在垂直于阵列基板11所在平面的方向上,黑色矩阵121分别与主像素电极1621和次像素电极1622错开设置。该设置可以提高像素开口率,进而提升了液晶显示面板的穿透率,进一步提升了液晶显示面板的显示质量。
在本申请第二实施例中,黑色矩阵121包括第一边界线121a,第一边界线121a位于黑色矩阵121靠近像素电极162的一侧,公共电极线14包括第二边界线14a,第二边界线14a位于公共电极线14靠近栅极15的一侧。在垂直于阵列基板11所在平面的方向上,第一边界线121a到栅极15的距离不小于第二边界线14a到栅极15的距离。
具体的,第一边界线121a到栅极15的距离大于或者等于第二边界线14a到栅极15的距离。当第一边界线121a到栅极15的距离等于第二边界线14a到栅极15的距离时,黑色矩阵121靠近栅极15的一侧与公共电极线14靠近栅极15的一侧对齐。由于栅极15附近设置有遮光电极161,上述设置在遮蔽栅极15附近漏光区域的同时,可以最大程度减小黑色矩阵121的覆盖面积,不仅提高了像素开口率,还可以节约工艺成本,从而进一步提升了产品竞争力。
本申请第二实施例提供的液晶显示面板100通过用遮光电极161覆盖栅极15和公共电极线14之间的间隔区域AA’,并将遮光电极161与像素电极162电性连接,使得遮光电极161和像素电极162具有相同电位,进而在暗态时,位于间隔区域AA’的液晶13与像素开口区的液晶13电场保持一致,避免了该处的液晶13因受到栅极15附近电场的影响而发生异常偏转。当面板受到按压或挤压时,即使阵列基板11和彩膜基板12发生偏移而出现对位异常,由于偏移区域的液晶13可以保持暗态不透光状态,从而有效防止了偏移区域发生漏光现象,提升了液晶显示面板的画质。此外,通过将黑色矩阵121和像素电极162错开设置,还可以提高像素开口率,从而进一步提升了显示面板的显示质量。
本申请还提供一种显示装置,该显示装置包括液晶显示面板100,该液晶显示面板100为本申请上述任一实施例中的液晶显示面板100。其中,液晶显示面板100的具体结构可参见前述实施例的描述,在此不再赘述。
相较于现有技术中的液晶显示面板,本申请提供的液晶显示面板通过用遮光电极覆盖栅极和公共电极线之间的漏光区域,并使得遮光电极和像素电极具有相同电位,解决了栅极附近因液晶异常偏转而导致的漏光问题,提升了液晶显示面板的画质。
