【技术领域】
本发明涉及液晶显示领域，特别是涉及一种液晶显示面板及其制造方法以及液晶显示装置。
【背景技术】
目前，在平板显示装置中，薄膜晶体管液晶显示器（Thin Film Transistor Liquid Crystal Display，TFT-LCD）在当前的平板显示器市场中占据了主导地位。并且，近年来，窄边框的产品已经成为了客户需求的主要产品趋势。
在TFT-LCD中，导电盘(Transfer Pad)是必要设计之一，其主要功能是为了导通TFT（Thin Film Transistor，薄膜晶体管）基板和CF（Color Filter，彩色滤光片）基板，进而对TFT-LCD中的液晶形成驱动电场。
请参见图1，图1是现有技术的液晶显示面板的结构设计示意图。如图1所示，配向膜11的边缘位于液晶显示面板的显示区域12的边缘的外侧，在配向膜11的边缘外侧和液晶显示面板的切割边缘15之间设置框胶涂布区域13以及导电盘14。

在本实施例中，TFT基板22包括导电盘221，导电盘221紧邻显示区域26的边缘的外侧设置在TFT基板22的内表面上，并且第一配向膜24覆盖在导电盘221上。其中，框胶23的涂布区域设置在TFT基板22上，并且框胶23的涂布区域的边缘位于显示区域26的边缘的外侧。
在本实施例中，导电盘221和框胶23的涂布区域均设置于显示区域26的边缘与第一配向膜24的边缘之间的区域。即，第一配向膜24完全覆盖导电盘221，框胶23的涂布区域完全设置在第一配向膜24上。此外，第二配向膜25设置在CF基板21的公共电极28上，并且第二配向膜25的边缘设置在显示区域26的边缘的外侧。
请再参见图4-5所示，图4是在电子显微镜下金属球压穿配向膜的实验结果示意图，图5是金属球压穿配向膜的压痕在胶框上的示意图。在将配向膜扩大到覆盖导电盘点位，且将金属球涂布在配向膜上的实验条件下，如图4所示，实验证实，在CF基板21和TFT基板22对盒后，金属球能够压穿配向膜，即：导电盘221通过金属球压穿第一配向膜24和第二配向膜25与CF基板21的公共电极28连接导通。其中，压痕231为金属球在框胶23上的压痕，压痕232为金属球在配向膜（第一配向膜24或第二配向膜25）上的压痕。
下文以32寸液晶显示面板20和一个导电盘221进行说明。在其他实施例中，在TFT基板22上设置导电盘221的数量越多，导电盘221与CF基板21的公共电极28导通率越好。
在本实施例中，如图2所示，导电盘221的中心位置和液晶显示面板20的显示区域26在同一平面上的距离为L4约为1.7mm，导电盘221的中心位置和液晶显示面板20的切割边缘27在同一平面上的距离L5约为1.5mm。因此，本实施例的液晶显示面板20的边框的宽度为L6=L4+L5=3.2mm。
如前所述，相对于现有技术中液晶面板的导电盘14设计在配向膜11的外侧，而本实施例将导电盘221和框胶23的涂布区域向内移动至第一配向膜24区域，使第一配向膜24覆盖导电盘221，框胶23的涂布区域完全设置在第一配向膜24上，以使本实施例的液晶显示面板20的边框的宽度为3.2mm，缩减了现有技术中边框宽度（宽达6mm左右）的一半以上，进而显著节省液晶显示面板20的显示区域26的边缘到液晶显示面板20切割边缘27的距离，实现液晶显示面板20的窄边框设计，提高用户的体验效果。
应理解，在本发明的其他实施例中，本领域的技术人员完全可以将图3所示的第二配向膜25的边缘设置在框胶23密封区域的内侧，如：第二配向膜25的边缘与显示区域26的边缘一致，与本发明图3所示的第一实施例不同之处在于：此时，在CF基板21和TFT基板22对盒后，导电盘221通过框胶23的金属球压穿第一配向膜24与CF基板21的公共电极28连接导通。
请参见图6，图6是根据本发明第二实施例的液晶显示面板的结构设计示意图。如图6所示，第二实施例的液晶显示面板与第一实施例的液晶显示面板20在结构设计上的不同之处在于：框胶33的涂布区域部分设置在第一配向膜34上，即：框胶33的涂布区域与第一配向膜34部分重合。其中，导电盘321的中心位置和液晶显示面板的显示区域36在同一平面上的距离为L7约为1.7mm，导电盘321的中心位置和液晶显示面板的切割边缘37在同一平面上的距离L8约为1.5mm。因此，本实施例的液晶显示面板的边框的宽度为：
L9=L7+L8=3.2mm。
值得注意的是，本领域的技术人员完全可以通过增加框胶23中混入的金属球的含量来增加导电盘与CF基板的公共电极导通率。此外，在其他实施例中，本领域的技术人员还可以将金属球设置为带刺金属球。
如图7所示，本发明进一步提供一种上述液晶显示面板的制造方法，其包括以下步骤：
步骤S1：提供第一基板，在第一基板上沉积导电盘；
在步骤S1中，第一基板为TFT基板，导电盘紧邻液晶显示面板的显示区域的边缘的外侧设置在第一基板的内表面上。此外，在第一基板上还进一步包括数据线、扫描线、TFT开关以及像素电极等用于驱动液晶显示面板的线路，其中，导电盘可在沉积TFT开关结构的同时进行沉积。液晶显示面板的第一基板、导电盘等不涉及本发明主要改进之处的具体制程方法可参照现有的技术，在此不进行详细说明。
步骤S2：在第一基板的配向膜涂布区域涂布第一配向膜，且第一配向膜覆盖在导电盘上；
步骤S3：在框胶中混入金属球后将框胶涂布在第一配向膜上，其中，框胶涂布区域的边缘位于液晶显示面板的显示区域的边缘的外侧，且框胶涂布区域至少部分设置在第一配向膜上；
步骤S4：提供第二基板，在第二基板上涂布第二配向膜；
在步骤S4中，第二配向膜可仅涂布在液晶显示面板的显示区域，也可涂布到液晶显示面板的显示区域的外侧。
步骤S5：将第一基板和第二基板对盒。
在本实施例中，由于金属球是在具有弹性的球状高分子材料上电镀一层导电性能良好的金属，因此金属球存在一定的压缩率，在第一基板和第二基板对盒后，金属球可压穿第一配向膜和第二配向膜，实现第一基板和第二基板导通。
其中，第一配向膜的厚度和第二配向膜的厚度优选为1000Å。
进一步的，如图8所示，本发明还提供一种液晶显示装置，该液晶显示装置包括液晶显示面板41以及背光模组42，背光模组42为液晶显示面板41提供光源，其中液晶显示面板41为上述实施例的液晶显示面板，在此也不再赘述。
综上，本发明的液晶显示面板及其制造方法以及液晶显示装置通过将导电盘和框胶的涂布区域向内移动至第一配向膜区域，使第一配向膜覆盖导电盘，框胶的涂布区域至少部分设置在第一配向膜上，以显著节省液晶显示面板的显示区域边缘到液晶显示面板的切割边缘的距离，从而减少边框的宽度，实现液晶显示面板的窄边框设计，提高用户的体验效果。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
