Description

PSVA液晶显示面板 技术领域
本发明涉及显示面板制造领域，尤其涉及一种PSVA液晶显示面板。
 背景技术
PS-VA技术中，液晶中需加入化学单体，在配向过程中，化学单体受紫外光照射，聚合形成polymer bump（聚合物凸点），用于固定液晶形成预倾角。PS-VA的制程工艺为，对基板加电压序列，液晶在电场作用下有序倾倒，接着保持电压不变，同时加紫外光，使化学单体聚合，固定液晶形成预倾角。
对于PSVA产品，配向制程一般有两种方式。A.Array probe curing（阵列基板侧配向电路），curing pad（金属触板）设计在array（阵列基板）侧，加电顶针（Pin）接触curing pad，对面板加电配向；B. CF probe curing（彩膜基板侧配向电路），因加电顶针（Pin）直接接触CF基板，Array侧无curing pad设计。Array侧讯号通过金胶（Au）点，把电讯号导向Array。
随着世代线越来越大，从6代线到8.5代线，再发展到以后的10.5代线，每片基板可设计容纳的panel（显示面板）数量可能会越来越多，对于Array probe curing，每个panel都会有一组curing pad；尤其对于GOA（Gate on Array）产品，Curing pad的数量会更多。
另外，配向时相同讯号的pad无法通过设计进行相连，否则易造成Array检测的漏检，引起品质不良。
针对以上两点，对检测所需的治具Probe bar（探测棒）提出了高规格的要求，Probe bar太长，太大，易造成probe bar上的pin与curing pad接触不良，导致配向不良，画质下降。
综上所述，现有技术的PS-VA显示面板，液晶母板包含Panel片数越来越多，配向电路需要的curing pad数量增加，每一curing pad需要通过相对应的Pin连接Probe bar，导致Pin数量增多，增大了Pin与curing pad连接不良的风险。

本发明针对现有的PSVA液晶显示面板，阵列基板侧的配向电路中，每一curing pad需要通过相对应的Pin连接Probe bar，导致Pin数量增多，增大Pin与curing pad连接不良的风险的技术问题；本实施例能够解决该缺陷。
如图1所示，本发明提供的PSVA液晶显示面板，包括母板101，所述母板101包括至少两块子显示面板102。
所述子显示面板102包括：彩膜基板，所述彩膜基板至少包括：第一玻璃衬底、以及制备于所述第一玻璃衬底一侧的公共电极层；阵列基板，与所述彩膜基板相对设置；所述阵列基板面向所述彩膜基板的一侧设置有驱动电路、TFT（Thin Film Transistor，薄膜晶体管）器件阵列、以及靠近所述阵列基板边缘的至少两个配向模块；所述驱动电路包括：用以向所述TFT器件传导数据信号的数据线，以及用于向所述TFT器件传导控制信号的扫描线，所述扫描线与所述数据线异面垂直相交形成像素单元。
每个所述配向模块至少包括两条配向线路，每条所述配向线路的输入端连接有一金属触板106，所述配向线路的输出端连接所述驱动电路；属于同一所述配向模块的所述配向线路为相同讯号的线路。
探测棒107，位于所述阵列基板的一侧；所述探测棒107的一侧设置有至少两个探测针108，所述探测针108与相对应的所述金属触板106接触连接；所述探测棒107可通过所述探测针108，将配向信号导入至相对应的配向模块。
属于同一所述配向模块的两个所述金属触板106之间通过导电金球连接，并且，两个所述金属触板106通过所述导电金球连接所述公共电极层；所述探测针108与相对应的所述配向模块的其中一个所述金属触板106接触连接。
各所述金属触板106呈一字型排列，将相同讯号的所述金属触板106成为一组，并在每一组所述金属触板106表面涂布金属胶层110，所述金属胶层110内均匀分布有多个所述导电金球，使得并列的相同讯号的所述金属触板106之间导通；同一组所述金属触板106只需连接一个所述探测针108即可实现相同讯号配向线的同时导通。

如图2a、2b所示，本发明的PSVA液晶显示面板，包括阵列基板201；金属触板202，制备于所述阵列基板201表面；彩膜基板，与所述阵列基板201相对设置；公共电极层203，制备于所述彩膜基板表面；以及金属胶层204，位于所述金属触板202与所述公共电极层203之间，所述金属胶层204内按照一定比例均匀分布有导电金球205，用以实现所述金属触板202与所述公共电极层203的电性连接；所述导电金球的尺寸大小为微米量级，与实际面板的盒厚相对应；所述金属触板的尺寸为毫米量级，一个所述金属触板表面分布有500至1000颗所述导电金球。
由于所述公共电极层203需要与所述像素电极之间形成电势差，因此需要使所述公共电极层203与所述像素电极具有不同的电压。
不同讯号的所述金属触板202所对应的公共电极区域之间绝缘设置，以实现不同讯号的单独导入。例如，将所述公共电极层203经图案化形成至少两个所述公共电极区域，所述公共电极区域与相对应的所述金属触板202连接。

例如，相邻所述公共电极区域的间隔宽度为30um～300um。
所述驱动电路包括数据线、扫描线以及公共线；所述数据线包括红色子数据线、绿色子数据线以及蓝色子数据线。
所述阵列基板201表面设置有数据讯号配向模块、扫描讯号配向模块和公共讯号配向模块；其中，所述数据讯号配向模块包括至少两条数据讯号配向线，所述数据讯号配向线连接所述数据线；所述扫描讯号配向模块包括至少两条扫描讯号配向线，所述扫描讯号配向线连接所述扫描线；所述公共讯号配向模块包括至少两条公共讯号配向线，所述公共讯号配向线连接所述公共线。
进一步，所述数据讯号配向模块包括：红色像素配向模块、绿色像素配向模块以及蓝色像素配向模块；所述红色像素配向模块对应连接所述红色子数据线，所述绿色像素配向模块对应连接所述绿色子数据线，所述蓝色像素配向模块对应连接所述蓝色子数据线。
所述公共电极层203的膜厚为200Å～1500Å。
所述公共电极层203的电极材料采用ITO（Indium Tin Oxides，铟锡氧化物半导体透明导电膜）或者IZO（indium-doped zinc oxide，掺铟氧化锌氧化物半导体透明导电膜）。
本发明的有益效果为：相较于现有的PSVA液晶显示面板，本发明提供的PSVA液晶显示面板，阵列基板201侧的配向电路，将相同讯号的curing pad成组连接Pin，进而减少Pin数量，简化curing pad与Probe bar的连接；以解决每一curing pad需要通过相对应的Pin连接Probe bar，导致Pin数量增多，增大Pin与curing pad连接不良的风险的技术问题。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
