Description

液晶面板的制造方法及液晶面板、 液晶显示装置
【技术领域】
本发明涉及液晶显示领域， 更具体的说， 涉及一种液晶面板的制造方法及 液晶面板、 液晶显示装置。
【背景技术】
液晶显示面板是液晶显示装置的主要组件， 其包括阵列基板、 彩膜基板以 及封闭在阵列基板和彩膜基板之间的液晶， 其中， 液晶通过涂覆在玻璃上的配 向层进行配向， 使液晶按特定的方向排列。
如图 1 是一种现有的液晶面板的边缘处局部截面图， 其包括阵列基板和彩 膜基板； 所述彩膜基板包括上层玻璃 10 ( top plate ), 该上层玻璃 10上设置有上 电极 30 ( Top electrode ), 所述阵列基板包括下层玻璃 20 ( bottom plate ), 该下 层玻璃 20上设置有下电极 40 ( bottom electrode ), 在上层玻璃 10与下层玻璃 20 上还涂覆有配向层 50 ( Alignment laye ); 图 1中， A到 A，连线表示可视区 (active area)的可视边界 101 ; 而 B到 B，连线表示配向层 50的配向边界 51 ; 由于受到配 向层 50涂布精度以及在配向层 50涂布边缘处会产生膜厚不均勾的情形等因素 的限制， 因此， 可视边界 101与配向边界 51之间必须要预留一段间隔 X, 否则 面板容易在可视区内的边缘处发生液晶配向不良或是显示不均匀（mura)等不良 现象。
图 1 中， Y代表框胶 60(sealant)涂布的范围即框胶区， 其中框胶 60中已经 含有具有支撑液晶盒厚 (cell gap)的间隙子 (spacer) ； 而 Z代表可涂布金球 70(Au ball)的空间即中转区（ransfer pad)， 一般常见的垂直配向（Vertical alignment)或是 扭转向列型（Twist Nematic)等显示模式在上层玻璃 10 都具有透明的上电极 30(Top electrode) , 但实际的液晶面板仅会在下玻璃 20处进行印刷电路板 (PCB) 或是 IC的连接 ( bonding ), 所以上板的上电极 30必须要透过金球 70(Au ball) 将下电极 40的讯号传递至上电极 30。 一般而言， 配向层 (Alignment layer)通常具有很高的电阻值， 因此当配向层 覆盖到中转区 （ transfer pad )处的上电极或是下电极， 金球 (Au ball)就无法有效 地将下电极的讯号传递至上电极， 液晶面板的显示即会出现异常。 所以， 如图 1 所示： 为了使中转区 Z ( transfer pad ) 的金球 70能够有效地运作， 配向层 50的 边缘必须要与中转区 Z ( transfer pad )保持一段距离， 避免配向层 50在涂覆时 覆盖住中转区 Z， 造成金球 70(Au ball)不能能正常导通上下板电极， 所以此设计 在玻璃边缘处通常会具有较大宽度的边框 (此处边框代表玻璃上非可视区域的宽 度)。
【发明内容】
本发明所要解决的技术问题是提供一种窄边框的液晶面板的制造方法。 本发明的目的是通过以下技术方案来实现的： 一种液晶面板的制造方法， 包括步骤：
A: 在液晶面板的电极表面， 至少对与金球接触的接触表面进行表面处理以 减小所述接触表面对配向液的附着作用， 使配向液无法披覆在所述接触表面上； B: 进行配向液的涂布或印刷。
优选的， 所述步骤 B 中， 进行配向液的涂布或印刷时， 配向液的涂布或印 刷边界至少在所述液晶面板的框胶区内或在框胶区的边界外。 这样， 在配向层 形成时， 边缘处的配向层层厚较为均 ， 从而使边缘处的液晶分子也得到良好 的配向， 使得可视区的边界可以进一步接近于框胶区， 提高可视区的范围， 同 时使得边框的范围变窄。
优选的， 所所述步骤 B 中， 所述框胶区内还设有用于设置金球的中转区， 进行配向液涂布或印刷时， 配向液的涂布或印刷边界在所述中转区的边界外。 以获得可视区的边缘处的配向层层厚更均勾， 使得可视区的边界更加接近于框 胶区， 提高可视区的范围， 同时使得边框的范围变窄。
优选的， 所述步骤 A中， 在电极的中转区上金球与所述电极的接触表面进 行表面处理是在所述接触表面涂覆一层亲油性的膜层。 涂覆亲油性膜层的方式 比较方便， 快捷， 易于加工。
优选的， 所述步骤 A中， 在电极的中转区上金球与所述电极的接触表面进 行表面处理是对所述接触表面进行抛光处理， 降低所述中转区表面对配向液的 附着作用。 进行抛光处理， 加工简单， 不需要外加材料。
优选的， 所述步骤 A中， 对所述整个中转区的表面进行表面处理。 这样使 的中转区整个表面均无配向层， 确保金球与电极的接触。
一种液晶面板， 包括对置的上层玻璃及下层玻璃， 所述上层玻璃上设置有 上电极， 所述下层玻璃上设置有下电极， 所述上电极与下电极的边缘区域设有 用于布置金球的中转区； 所述上层玻璃及下层玻璃的的内侧面设有配向层， 而 中转区的内侧面分别设置有无配向层附着的处理层。
优选的， 所述处理层为亲油性的膜层。 涂覆亲油性膜层的方式比较方便， 快捷， 易于加工。 行抛光处理， 加工筒单， 不需要外加材料。
优选的， 所述配向层的边界在所述液晶面板的框胶区内或在框胶区的边界 外。 使得可视区的边界更加接近于框胶区， 提高可视区的范围， 同时使得边框 的范围变窄。
优选的， 所述中转区在所述框胶区内， 所述配向层的边界在所述中转区的 边界外。 以得到较好的配向层边缘。
优选的， 所述配向层的边界在所述框胶区的边界外。 以得到较好的配向层 边缘， 同时以便于加工， 不用过高的精度便可。
优选的， 所述中转区的整个电极上表面上都为无配向层附着的处理层。 确 保金球与电极的接触， 确保通信的可靠。
一种液晶显示装置， 其特征在于， 包括了上所述的液晶面板。 本发明由于在液晶面板的配向层涂布或印刷之前， 在上层玻璃和下层玻璃 需要涂布金球粒子的位置电极表面 （即中转区） 处先涂布一层亲油性的膜层或 是进行表面处理以减小该区域对配向液的附着作用， 这样， 可以将配向液的涂 布范围进一步扩大， 即使扩大到框胶区的中转区范围上， 配向液配向液也无法 披覆在该位置的表面上， 在之后的烘烤形成配向层时中转区表面也不会有配向 层的产生。 在此情况下， 配向层的边界可以做的更宽， 也就是说， 配向层的边 界与框胶区或是其中的中转区不需要再预留间隔空间， 即使配向液涂布到该中 转区上， 也不会在该中转区的电极表面形成配向层， 使可视区随之往框胶方向 扩大， 同时使得配向层在靠近框胶处的膜层均匀性更好、 精度更高， 进而提高 液晶面板靠近框胶区处的显示效果， 使得可视区的边界进一步得以向框胶偏移。

【具体实施方式】
下面结合附图和较佳的实施例对本发明作进一步说明。
本发明提供一种液晶面板的制造方法及使用该方法所获得的液晶面板、 液 晶显示装置， 所述液晶面板的制作方法包括步骤： A、 在电极表面框胶区内的中 转区上， 至少对与金球接触的接触表面进行表面处理以减小所述接触表面对配 向液的吸附作用， 使配向液无法披覆在所述接触表面上， 所述接触表面为所述 电极的中转区的表面； B、 进行配向液的涂布或印刷。 所述液晶面板包括上层玻 璃及下层玻璃， 所述上层玻璃及下层玻璃的边缘设置有框胶区用于涂覆框胶， 所述上层玻璃以及下层玻璃表面设置有电极层， 所述电极层上还设置有配向层； 所述配向层的边界在所述框胶区内或在框胶区的边界外。
如图 2所示为根据本发明的一种实施例， 液晶面板包括上层玻璃 10、 下层 玻璃 20以及设置在两层玻璃中间的液晶， 在上层玻璃 10的表面上设置有上电 极 30, 在上电极 30之上还设置有配向层 50, 在下层玻璃 20上也设置有下电极 40以及配向层 50。 液晶面板的边缘处， 上层玻璃 10与下层玻璃 20之间还设置 有框胶 60, 框胶 60的设置区域即框胶区为图中 Y所示的范围， 在框胶区 Y内， 还设置有中转区 Z, 中转区 Z的设置区域为图中 Z所示的范围， 中转区 Z内设 置有金球 70, 用于将下电极 40的信号传到上电极 30上。 配向层 50的配向边界 51在框胶区 Y的框胶边界 61外， 但是， 在中转区 Z的电极表面上， 并没有配 向层的存在， 因此， 金球 70仍然可以将下电极 40的信号传递到上电极 30。 由 于配向层 50的配向边界 51在框胶区 Y的框胶边界 61外， 因此， 可视区的可视 边界 101 也随之向液晶面板的边界偏移， 进而使得可视区的范围变的更大， 同 时， 减小了液晶面板的边框宽度。 如图 1所示， 现有液晶面板中， 可视边界 101 到液晶面板的边界的距离为 dl , 如图 2所示， 本实施例中， 可视边界 101到液 晶面板的边界的距离为 d2, 通过对比， dl>d2, dl和 d2分别是液晶面板的边框 宽度， 也就是说， 本实施例中， 液晶面板的边框要比现有液晶面板的边框窄。
在本实施例中， 在液晶面板的制造过程中， 添加了对中转区 Z的表面处理 工艺， 使得中转区 Z的表面形成一处理层， 从而使得在中转区 Z, 电极的表面 在配向层涂覆和印刷工艺中不会覆盖有配向层。 如图 3 所示， 以本实施例的下 层玻璃 20为例， 在中转区 Z内， 对下电极 40的表面进行表面处理形成处理层 41 , 即在下电极 40的表面涂覆一层亲油性的薄膜， 以减小中转区 Z处的下电极 40的表面对配向液的附着作用， 使配向液无法披覆在下电极 40的表面上， 从而 在配向层形成后， 在中转区 Z处的电极表面上， 不会形成有配向层。 而上层玻 例的处理方式与下层玻璃的一样， 同样在中转区 Z对应的电极表面， 进行亲油 性薄膜的涂覆， 然后才进行配向液的印刷或涂布。
另外， 对中转区 Z的电极表面进行处理的方式也可以是通过对该处的电极 表面进行抛光处理， 从而减小该处表面对配向液的附着作用。
在本实施例中， 对中转区 Z的表面处理是为了使此处的电极表面没有配向 层的覆盖， 从而不会影响金球的导电， 但是金球不会与整个中转区 Z的表面接 触， 实际上， 只需要对与金球接触的接触表面进行表面处理以减小所述接触表 面对配向液的附着作用， 使配向液无法披覆在所述接触表面上即可， 所述接触 表面为所述电极的中转区 Z的表面。 在进行配向液的涂布或印刷时， 配向液的 涂布或印刷边界至少在框胶区内或在框架区的边界外， 最好的效果是， 配向液 的涂布或印刷范围要覆盖住中转区 Z的电极表面， 即配向液的边界在中转区 Z 的边界外， 以使配向液靠近框胶区的地方形成较好较均 的配向层， 使得此处 的显示效果与液晶面板内部的显示效果无差异。 如图 4所示， 配向层的配向边 界 51处于中转区边界 67外， 而可视边界 101靠近框胶区， 另外， 在配向液的 涂布或印刷时， 不能将配向液的边界扩展到接合区 90处， 避免影响到接合区 90 的使用。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明， 不 能认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通 技术人员来说， 在不脱离本发明构思的前提下， 还可以做出若千简单推演或替 换， 都应当视为属于本发明的保护范围。
