Description

液晶面板的制造方法以及液晶玻璃
【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以 及液晶玻璃。
【背景技术】
在液晶显示装置的 PSVA ( Polymer Stabilized Vertical Aligment, 聚合物稳 定型垂直配向技术)制程需要在液晶 (LC ) 中或是配向层(PI )表面加入对光 线敏感的单体分子( monomer )以在后续的 PS VA制程中反应形成辅助配向的聚 合物 (polymer ), 如图 1所示, 在 PSVA制程前的 SUV (框胶紫外光固化)制 程中, 使用紫外光(UV ) 照射框胶 15 ( sealant ) 时, 需要使用一个紫外光掩膜 7 ( UV Mask )去阻挡紫外光的照射以避免可视区 (Active area/AA区)的液晶分子 8在 PSVA制程之前受到紫外光的照射而提前作用 (此即所谓的 pre-cured作用), 由于还必须要考虑斜向光的作用以及紫外光掩膜 7 ( UV Mask )的制作或对位精 度等,因此设计时可视区 (Active area/AA区)的边界必须要距离紫外光掩膜 7( UV Mask ) 的边界一段距离, 否则在可视区周围会因单体分子提前反应而使得液晶 预倾角(pre-tilt)与大部分可视区的液晶分子不同, 可视区周边有画面不均匀 ( around mura ) 的现象发生, 即如图 2所示, 虚线框中的液晶分子由于受到紫 外光的作用而提前倾倒, 致使在后续的 PSVA制程中不能形成垂直配向, 从而 造成液晶面板周边处的画面不均匀, 这样也影响到液晶显示装置的窄边框化。
【发明内容】
本发明所要解决的技术问题是提供一种提高液晶显示装置的显示效果, 增 大液晶面板可视区的液晶面板的制造方法以及液晶玻璃。
本发明的目的是通过以下技术方案来实现的: 1、一种液晶面板的制造方法, 包括: A: 在彩膜基板上形色阻材料层时, 在彩膜基板对应于阵列基板焊盘的位置 通过形成堆叠的红色色阻材料层、 绿色色阻材料层以及蓝色色阻材料层形成凸 起的步骤;
B: 在彩膜基板上形成导电层, 并使导电层覆盖所述凸起的步骤;
C: 将彩膜基板与阵列基板压合使所述导电层与所述焊盘接触的步骤;
D: 使用紫外光固化框胶的步骤。
本发明的目的还可以通过以下技术方案来实现: 一种液晶面板的制造方法, 包括:
A: 在彩膜基板对应于阵列基板焊盘的位置形成凸起的步骤;
B: 在彩膜基板上形成导电层, 并使导电层覆盖所述凸起的步骤;
C: 将彩膜基板与阵列基板压合使所述导电层与所述焊盘接触的步骤;
D: 使用紫外光固化框胶的步骤。
优选的, 所述步骤 A中, 在彩膜基板上形成所述凸起是在所述彩膜基板形 成色阻的步骤中通过在所述与焊盘对应的位置上形成堆叠的色阻材料层形成 的。 利用在彩膜基板上形成色阻的步骤形成堆叠的色阻材料层形成凸起, 从而 不需要另外为了形成凸起而增加新的工艺步骤。
优选的, 所述步骤 A中, 在彩膜基板上形成堆叠的色阻材料层是通过在所 述彩膜基板上对应所述阵列基板焊盘的位置形成两层色阻材料层形成的。 根据 色阻材料的厚度, 加上导电层的厚度, 可以使用两层色阻材料层堆叠形成凸起。 或两层色阻材料层分别为红色色阻材料层与蓝色色阻材料层; 或两层色阻材料 层分别为绿色色阻材料层与蓝色色阻材料层。 根据色阻材料层的形成先后工艺, 可以选择相应的色阻材料层组合, 以方便色阻的形成以及凸起的形成。
优选的, 所述步骤 A中, 在彩膜基板上形成堆叠的色阻材料层是通过在彩 膜基板上对应所述阵列基板焊盘的位置形成三层色阻材料层形成的。 根据不同 液晶面板的厚度, 也可以利用三层色阻材料层堆叠形成凸起。 优选的, 所述三层色阻材料层分别为红色色阻材料层、 绿色色阻材料层以 及蓝色色阻材料层。 利用三原色色阻材料层形成堆叠的凸起, 从而不需要增加 额外的工艺步骤。
优选的, 所述步骤 B中, 所述导电层为 ITO材料层。 ITO材料透明, 不影 响液晶面板的透光性。
优选的, 所述步骤 A中, 在彩膜基板上形成所述凸起是在所述彩膜基板形 成色阻以及黑矩阵的步骤中通过在所述与焊盘对应的位置上形成堆叠的黑矩阵 材料层以及色阻材料层形成的。 根据液晶面板上的材料层制作工艺, 也可以利 用三层色阻材料层堆叠写成凸起。
一种液晶玻璃, 包括上层基板以及下层基板, 所述下层基板包括有多个阵 列基板单元, 所述上层基板包括有多个与所述阵列基板单元对应的彩膜基板单 元; 所述下层基板上的每个阵列基板单元的边缘处设置有焊盘; 所述彩膜基板 单元对应于所述焊盘的位置设置有凸起, 所述彩膜基板单元上设置有导电层, 所述导电层覆盖所述凸起, 所述凸起上的导电层与所述焊盘接触。
本发明由于在液晶面板的制造方法中在彩膜基板上对应于阵列基板焊盘的 位置处形成凸起, 并在凸起上设置导电层, 使得在紫外光固化框胶的步骤中, 彩膜基板与阵列基板导通而具有相同的电位, 这样就避免了由于紫外光照射下 使得被照射的液晶分子发生提前倾倒形成预倾角, 也就避免了在液晶面板的边 缘处由于液晶分子具有预倾角而造成边缘处画面不均勾的现象; 也就是说, 液 晶面板边缘的液晶分子紫外光照射时液晶面板的边缘处不会发生液晶分子提前 倾倒, 从而使得液晶面板边缘处的显示效果均匀, 可视区的范围进一步扩大, 也就是扩大了液晶面板的有效显示区域, 使得液晶显示装置的窄边框化可以更 容易实现。

【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。
如图 11所示为本发明所述的液晶面板的制造方法所包含的几个步骤:
A: 在彩膜基板对应于阵列基板焊盘的位置形成凸起的步骤; B: 在彩膜基 板上形成导电层, 并使导电层覆盖所述凸起的步骤; C: 将彩膜基板与阵列基板 压合使所述导电层与所述焊盘接触的步骤; D: 使用紫外光固化框胶的步骤; 以 及后续的 PSVA制程步骤。
如图 3-5所示, 在框胶 15外、 阵列基板 20的边缘处设置有焊盘 21 , 在液 晶面板的 PSVA制程之前,需要对彩膜基板 10的边缘进行切割以使阵列基板 20 上的焊盘 21棵露出来, 从而可以施加电压进行线路测试。
如图 6所示, 在对彩膜基板 10的边缘进行切割之前, 在彩膜基板 10的制 造工艺中, 包括本发明所述的步骤 A以及步骤 B, 即在彩膜基板的待切割边缘 对应于阵列基板焊盘 21的位置处形成一凸起 30, 并在该彩膜基板 10的导电层 11形成步骤中使导电层覆盖凸起 30。 在之后的将彩膜基板 10与阵列基板 20压 合的步骤中, 包括本发明所述的使导电层 11与焊盘 21接触的步骤, 从而使压 合后的彩膜基板 10上的导电层 11与阵列基板 20上的焊盘 21之间具有相同的 电位, 而焊盘 21与阵列基板 20上的线路是连接的, 从而使上下对置的彩膜基 板 10与阵列基板 20间不存在电位差。 如图 7及图 8所示, 在本发明所述的步 骤 D即紫外光固化框胶的步骤中, 由于上下对置的彩膜基板 10与阵列基板 20 间不存在电位差,则液晶面板边缘处的液晶分子 8 (图中虚线框内的液晶分子 8 ) 在受到紫外光照射时就不会发生倾倒形成预倾角, 而是会自然的相对于配向层 表面垂直, 这样一来, 即使可视区(AA区)周边直接照射到紫外光其所造成之 画面不均匀的现象 (mura)也可以大幅改善,可视区边界与紫外边界之距离也可以 大幅缩短, 此外, PSVA模式的液晶显示器之窄边框化设计亦会更容易达成。
如图 9所示, 在本发明所述的步骤 A中, 在彩膜基板基板 10上形成凸起 30的工艺可以在彩膜基板的色阻形成步骤中, 利用不同色阻形成工艺的先后步 骤在彩膜基板上形成堆叠的色阻材料层, 从而形成凸起 30。 如图 9所示, 本发 明可提供的具体实施方式可以是在彩膜基板 10上形成第一色阻材料层 31 ,并在 形成第二色阻材料层 32的时候使第二色阻材料层 32的形成区域在要形成凸起 的位置与第一色阻材料层 31重合, 故而形成凸起。 第一色阻材料层 31以及第 材料层与蓝色色阻材料层; 或是绿色色阻材料层与蓝色色阻材料层。
如图 10所示, 本发明还可以提供另一种具体实施方式, 在彩膜基板 10上 形成第一色阻材料层 31 ,并在形成第二色阻材料层 32的时候使第二色阻材料层 32的形成区域在要形成凸起的位置与第一色阻材料层 31重合,同时再在重合处 再形成第三色阻材料层 33而最终形成凸起 30; 第一色阻材料层 31、 第二色阻 材料层 32以及第三色阻材料层 33分别可以是红色色阻材料层、 绿色色阻材料 层以及蓝色色阻材料层。
另外, 彩膜基板上的材料层形成制程及顺序分别是: 黑矩阵, 色阻材料(即 红色、 绿色以及蓝色色阻材料层) 以及 ITO层。 因此, 彩膜基板上的材料层并 不限于色阻材料, 因此也可以在其他材料层形成步骤中形成, 也可以在多种类 型的材料层形成步骤中形成, 如可以在黑矩阵材料层以及色阻材料层的形成步 骤中形成凸起, 或是这些材料层与 PI层共同形成的步骤中使黑矩阵、 色阻以及 PI层在对应于焊盘的位置处重合, 从而也可以形成凸起。
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, 还可以做出若干筒单推演或替 换, 都应当视为属于本发明的保护范围。
