Description

显示面板及显示装置 技术领域
本发明属于显示技术领域，具体涉及一种显示面板及一种显示装置。
背景技术
液晶显示技术广泛应用于电视、手机以及公共信息显示，液晶显示主要可以分为扭曲向列(Twisted Nematic，简称TN)模式、垂直排列(Vertical-Aligned，简称VA)模式、面内开关(In-Plane Switching，简称IPS)模式。其中，垂直排列模式的液晶显示技术具有高对比度、容易获得宽视角的特点，因此在大尺寸液晶显示装置产品方面得到了广泛应用。
随着显示技术的发展，目前垂直排列模式技术领域中出现了多畴(Multi-domain)显示技术。多畴显示技术即在电场作用下将一个亚像素区内的液晶的取向分成多个畴，不同畴的液晶之间的亮度差异在各个角度方向上互相补偿或抵消，即可在每一个亚像素区内实现多畴液晶显示，从而实现广视角化。但是，在现有技术中，由于不同亚像素区的相邻两个亚像素电极之间的间隙区附近存在液晶排列方向的差异，例如图1所示的8畴液晶排列，在相邻两个亚像素电极152(i)和151(i+1)之间的间隙区附近的液晶排列出现位错，在显示效果上会表现为暗区，图中152(i)为第i行栅线对应的第二亚像素电极，151(i+1)为第i+1行栅线对应的第一亚像素电极。
因此，如何设计出一种在相邻两个亚像素区的相邻两个亚像素电极之间的间隙区附近的液晶排列不会出现位错，从而实现显示上无暗区的显示装置已成为目前液晶显示技术领域中亟待解决的技术问题。
发明内容
针对现有技术中存在的上述技术问题，本发明的目的是提供一种显示面板及一种显示装置，其中，通过在第一基板的分属不同亚像素区的两个相邻亚像素电极之间的间隙区中设置凸起物，以减小间隙区附近的液晶排列位错造成的像素暗区，从而提高显示质量。

具体实施方式
为使本领域技术人员更好地理解本发明的技术方案，下面结合附图和具体实施方式对本发明的显示面板及显示装置作进一步详细描述。
第一实施例：
本实施例提供一种显示面板，该显示面板包括多个亚像素区。如图2至图4所示，显示面板包括对盒设置的第一基板2和第二基板1以及设置于第一基板2和第二基板1之间的液晶层3，第二基板1的与每一亚像素区相对应的每一个区域内均设置有第一亚像素电极151和第二亚像素电极152。如图4所示，在显示面板的分属不同亚像素区的相邻的第一亚像素电极151和第二亚像素电极152之间的间隙区中设置有凸起物24，凸起物24的投影至少部分覆盖与间隙区对应的液晶层3的区域。该显示面板中，通过设置凸起物24来调整相邻两个亚像素电极之间的间隙区附近的液晶层3中液晶分子30的排列，从而减小间隙区附近的液晶分子30的位错，减弱或消除了像素暗区。
在下文中，将以第一基板2是彩膜基板、第二基板1是阵列基板为例来进行说明。应该理解的是，彩膜基板和阵列基板有时会集成在一起以形成COA基板。
如图2所示，阵列基板1还包括垂直交叉设置的多条栅线11和多条数据线，每一亚像素区内设置的第一亚像素电极151和第二亚像素电极152沿数据线的延伸方向交替排列，栅线11穿过亚像素区、且每一亚像素区内的第一亚像素电极151和第二亚像素电极152位于对应栅线11的两侧。其中，第一亚像素电极151和第二亚像素电极152中均开设有狭缝，如图2所示，狭缝与栅线11所成角度的绝对值范围为30°～60°。例如，可以将狭缝沿逆时针方向与栅线11所成的锐角定义为正角，将狭缝沿顺时针方向 与栅线11所成的锐角定义为负角。
在图2中，与第i行栅线11(i)对应的亚像素电极包括第一亚像素电极151(i)和第二亚像素电极152(i)；第一亚像素电极151(i)和第二亚像素电极152(i)分别位于第i行栅线11(i)的两侧；与第i+1行栅线11(i+1)对应的亚像素电极包括第一亚像素电极151(i+1)和第二亚像素电极152(i+1)，第一亚像素电极151(i+1)和第二亚像素电极152(i+1)分别位于第i+1行栅线11(i+1)的两侧。其中，作为示例，与第i行栅线11(i)对应的第二亚像素电极152(i)与第i+1行栅线11(i+1)对应的第一亚像素电极151(i+1)相邻，该两个亚像素电极被称为分属不同亚像素区的两个相邻亚像素电极。
在本实施例的显示面板中，液晶分子30可以为负性液晶。位于同一亚像素区内的第一亚像素电极151和第二亚像素电极152使得对应亚像素区内的液晶分子30形成2n个具有不同取向的液晶畴，其中，n为自然数，且2≤n≤4。即多畴液晶显示模式可以为4畴液晶显示模式、8畴液晶显示模式甚至16畴液晶显示模式。在该多畴液晶显示模式的显示面板中，凸起物24设置于彩膜基板2中，凸起物24使得分属不同亚像素区的相邻的第一亚像素电极151和第二亚像素电极152之间的间隙区附近的液晶分子30的排列得到改善，从而减小间隙区中的液晶分子30的位错，减弱或消除了像素暗区。
作为一种示例，当n＝3时，该显示面板处于8畴液晶显示模式，每一亚像素区形成垂直排列的两个区域，该两个区域分别设置有第一亚像素电极151和第二亚像素电极152，第一亚像素电极151和第二亚像素电极152使得该亚像素区中的液晶层3形成8个不同的取向，即形成8畴液晶显示。
在本实施例的显示面板中，凸起物24为中轴对称形状(即，凸起物24关于其中轴对称)，凸起物24设置于与不同亚像素区相对应的相邻的第一亚像素电极151和第二亚像素电极152之间的间隙区的中心，且凸起物24垂直于显示面板的投影的中心点与间隙区的中心点重合。其中，彩膜基板2包括第二衬底20以及依 次设置于第二衬底20上方的彩膜层21、保护层22、公共电极层23和取向层(图3和图4中均未示出)，凸起物24的投影至少覆盖分属不同亚像素区的相邻的第一亚像素电极151和第二亚像素电极152之间的间隙区的中心宽度区域，宽度区域即指分属不同亚像素区的第一亚像素电极151和第二亚像素电极152沿数据线延伸方向形成的间隙区的尺寸，而中心宽度区域即指该宽度区域在对应间隙区沿着栅线延伸方向(栅线延伸方向垂直于数据线延伸方向)的中间区域。例如，分属不同亚像素区的相邻的第一亚像素电极151和第二亚像素电极152之间的间隙区的宽度范围为3μm-10μm，凸起物24在第二衬底20上的投影的最大尺寸为15μm-30μm。
在该显示面板中对凸起物24的位置不做限定，在实际显示面板的制备过程中可根据客户需求或显示精度进行灵活选择。例如：凸起物24可以设置于第二衬底20上，彩膜层21覆盖凸起物24；或者，凸起物24设置于彩膜层21上，保护层22覆盖凸起物24；或者，凸起物24设置于保护层22上，公共电极层23覆盖凸起物24；或者，凸起物24设置于公共电极层23上，取向层覆盖凸起物24。
同时应该理解的是，在本实施例的显示面板中对凸起物24的形状不做限制，凸起物24的形状包括长方体、四面体、楔形体、棱柱、立方体、圆柱体和半球体中的任一种。优选的是，凸起物24在第一衬底10上的投影形状为圆形，即上述凸起物24的形状至少具有一个圆形或弧形的部分，以便于凸起物24的制备。
为了保证凸起物24具有较佳的均衡液晶层3中的液晶分子30排列的效果，凸起物24的高度与液晶层3的厚度保持一定的关系，液晶层3的厚度越大，凸起物24的高度越高。例如，液晶层3的厚度范围为3μm-6μm，凸起物24的高度范围为1μm-2μm。
凸起物24可以采用感光树脂材料制备，并通过构图工艺形成，其中，构图工艺可以采用曝光、显影工艺，或，凸起物24还可以采用打印、喷墨等其他用于形成预定图形的工艺形成；可根 据本发明中所形成的凸起物24的结构来选择相应的构图工艺。本实施例的显示面板中的凸起物24的制备过程包括：涂覆感光树脂材料，对感光树脂材料执行曝光、显影工艺，以得到包括凸起物24的结构。
在本实施例的显示面板中，每一栅线11设置在同一亚像素区的第一亚像素电极151和第二亚像素电极152之间，并分别与第一薄膜晶体管T1的栅极和第二薄膜晶体管T2的栅极连接，使得第一亚像素电极151和第二亚像素电极152同时被扫描和驱动。具体的，与第i行栅线11(i)对应的第一亚像素电极151(i)通过与第i行栅线11(i)对应的第一薄膜晶体管T1(i)的漏极来连接第一数据线121(其与第一薄膜晶体管T1(i)的源极连接)，与第i行栅线11(i)对应的第二亚像素电极152(i)通过与第i行栅线11(i)对应的第二薄膜晶体管T2(i)的漏极来连接第二数据线122(其与第二薄膜晶体管T2(i)的源极连接)；与第i+1行栅线11(i+1)对应的第一亚像素电极151(i+1)通过与第i+1行栅线11(i+1)对应的第一薄膜晶体管T1(i+1)的漏极来连接第一数据线121(其与第一薄膜晶体管T1(i+1)的源极连接)，与第i+1行栅线11(i+1)对应的第二亚像素电极152(i+1)通过与第i+1行栅线11(i+1)对应的第二薄膜晶体管T2(i+1)的漏极来连接第二数据线122(其与第二薄膜晶体管T2(i+1)的源极连接)；第一数据线121上的数据信号Va(i)通过与第i行栅线11(i)对应的第一薄膜晶体管T1(i)的源极写入与第i行栅线11(i)对应的第一亚像素电极151(i)，第二数据线122上的数据信号Vb(i)通过与第i行栅线11(i)对应的第二薄膜晶体管T2(i)的源极写入与第i行栅线11(i)对应的第二亚像素电极152(i)；第i行栅线11(i)对应的第一亚像素电极151(i)上的电压Va(i)与第i行栅线11(i)对应的第二亚像素电极152(i)上的电压Vb(i)大小有一定差异，使第i行栅线11(i)对应的第一亚像素电极151(i)上的液晶分子的倾角不同于第i行栅线11(i)对应的第二亚像素电极152(i)上的液晶分子的倾角；在本实施例中，如图2所示，第i行栅线11(i)对应的第一亚像素电极151(i)上的液晶分子形成4畴排列，第i行栅线11(i) 对应的第二亚像素电极152(i)上的液晶分子形成另一个不同倾角的4畴排列，第i行栅线11(i)对应的亚像素区总共形成了8畴的液晶排列；第一数据线121上的数据信号Va(i+1)通过与第i+1行栅线11(i+1)对应的第一薄膜晶体管T1(i+1)的源极写入与第i+1行栅线11(i+1)对应的第一亚像素电极151(i+1)，第二数据线122上的数据信号Vb(i+1)通过与第i+1行栅线11(i+1)对应的第二薄膜晶体管T2(i+1)的源极写入与第i+1行栅线11(i+1)对应的第二亚像素电极152(i+1)；同样地，可以在第i+1行栅线11(i+1)对应的亚像素区形成8畴的液晶排列。
以顶栅型薄膜晶体管为例，如图3所示，薄膜晶体管包括：栅极141(连接图2中与栅极141同层形成的栅线11)、栅极141上方的栅极绝缘层142、栅极绝缘层142上方的有源层143、有源层143上方同层设置的源极144和漏极145、源极144和漏极145上方的钝化层146，钝化层146中开设的过孔(图3中，过孔中已填充亚像素电极的材料，因此未添加附图标记)。亚像素电极通过过孔与漏极145连接。
本实施例的显示面板中，阵列基板1还包括公共电极线(与栅极141同层形成)，如图2所示，该公共电极线包括与第i行第一亚像素电极151(i)对应的第一公共电极线131(i)和与第i行第二亚像素电极152(i)对应的第二公共电极线132(i)，第一公共电极线131(i)和第二公共电极线132(i)分别位于第i行栅线11(i)的两侧。其中，第一公共电极线131(i)包括朝向第一亚像素电极151(i)、且沿第一数据线121和第二数据线122方向延伸并与第一亚像素电极151(i)的投影至少部分重叠的部分，第一公共电极线131(i)与第i行的对应第一亚像素电极151(i)形成存储电容Csta(i)；第二公共电极线132(i)包括朝向第二亚像素电极152(i)、且沿第一数据线121和第二数据线122方向延伸并与第二亚像素电极152(i)的投影至少部分重叠的部分，第二公共电极线132(i)与第i行的对应第二亚像素电极152(i)形成存储电容Cstb(i)。以此类推，第i+1行第一亚像素电极151(i+1)的对应第一公共电极线131(i+1)与第i+1行的对 应第一亚像素电极151(i+1)形成存储电容Csta(i+1)，第i+1行第二亚像素电极152(i+1)的对应公共电极线132(i+1)与第i+1行的对应第二亚像素电极152(i+1)形成存储电容Cstb(i+1)。
本实施例中显示面板的电路原理图如图5所示，当栅极141被扫描时，第一数据线121上的数据信号Va(i)通过与第i行栅线11(i)对应的第一薄膜晶体管T1(i)写入存储电容Csta(i)、通过与第i+1行栅线11(i+1)对应的第一薄膜晶体管T1(i+1)写入存储电容Csta(i+1)，第二数据线122上的数据信号Vb(i)通过与第i行栅线11(i)对应的第二薄膜晶体管T2(i)写入存储电容Cstb(i)、通过与第i+1行栅线11(i+1)对应的第二薄膜晶体管T2(i+1)写入存储电容Cstb(i+1)，从而实现图像显示。
这里应该理解的是，在图5中，CLCa(i)和CLCb(i)分别为第i行第一亚像素电极151(i)和第i行第二亚像素电极152(i)与彩膜基板2上的公共电极层23形成的液晶电容，CLCa(i+1)和CLCb(i+1)为第i+1行第一亚像素电极151(i+1)和第二亚像素电极152(i+1)与彩膜基板2上的公共电极层23形成的液晶电容，液晶电容的电容值与存储电容的电容值相比要小很多，因此在讨论显示原理的时候，液晶电容通常可以忽略不计。
图1是在彩膜基板上未设置凸起物24的情况下在分属不同亚像素区的相邻两个亚像素电极之间的间隙区附近的液晶分子30的排列示意图，在此情况下将会出现较大的暗区(如图1中黑线包围的区域)，会严重影响显示质量，并造成亮度均匀度劣化、对比度下降和亮度降低。如图6所示，在彩膜基板2上设置凸起物24的情况下，在分属不同亚像素区的相邻两个亚像素电极之间的间隙区附近的液晶分子30的排列在凸起物24的作用下得到改善，从而减小间隙区附近的液晶分子30的位错现象，减弱或消除了像素暗区。
本实施例的显示面板中，通过在彩膜基板的分属不同亚像素区的两个相邻亚像素电极之间的间隙区中设置凸起物，从而改善两个相邻亚像素电极之间的间隙区附近的液晶分子排列，可以减 小间隙区附近的液晶分子排列造成的像素暗区，提高显示质量。
第二实施例：
本实施例提供一种显示装置，该显示装置包括第一实施例中的显示面板。
该显示装置可以为：液晶面板、电子纸、手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
由于该显示装置所采用的显示面板中，采用了广视角的多畴液晶显示技术，并通过在彩膜基板的分属不同亚像素区的两个相邻亚像素电极之间的间隙区中设置凸起物，从而改善相邻两个亚像素电极之间的间隙区附近的液晶分子排列，可以减小间隙区液晶分子排列位错造成的像素暗区，因此所述显示装置具有较佳的视角范围和较好的显示效果。
应该理解的是，以上实施方式仅仅是为了说明本发明的原理而采用的示例性实施方式，然而本发明并不局限于此。对于本领域内的普通技术人员而言，在不脱离本发明的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也属于本发明的保护范围。
