Description

显示面板及其制造方法和显示器件 技术领域
本发明的实施例涉及一种显示面板及其制造方法和显示器件。 背景技术
在液晶显示器制造工程中, 传统的取向层摩擦方法都是同一基板取向相 同, 因此显示器件具有只能显示一种显示模式的优势, 同时也显示出了该模 式的劣势。 将各种模式的优劣情况综合起来成为显示领域的目标。 半透半反 模式显示就是一种将透射与反射结合起来的显示模式, 提高了应用产品的性 能, 扩大了应用产品的应用领域, 所以研发的热度也在与日倶增。 纵观显示 领域的发展现状, 在户外应用的显示产品, 半透半反模式已备受关注。
光敏高分子作为活泼的高分子材料, 其应用的范围也在日益扩大。 在光 敏高分子的使用过程中, 主要是利用光照来进行光敏高分子的稳定和降解。 旋涂工艺可在塑料基板或者添加粘合剂后在玻璃基板上进行, 挥发掉有机溶 剂后, 进行取向工艺, 而后进行紫外光照射使得光敏高分子稳定以达到取向 效果。
发明人发现传统工艺中半透半反传统的取向工艺是使用树脂材料先做好 阶梯状的层状结构, 然后摩擦取向 rubbing工艺在阶梯状的基板上进行, 这 样的工艺结果使得阶梯交界处发生工艺不良, 进而影响画面的整体品质。 发明内容

为了更清楚地说明本发明实施例的技术方案, 下面将对实施例的附图作 简单地介绍,显而易见地,下面描述中的附图仅仅涉及本发明的一些实施例, 而非对本发明的限制。
图 1为本发明实施例提供的显示面板制造过程中的结构一示意图; 图 2为本发明实施例提供的显示面板制造过程中的结构二示意图; 图 3为本发明实施例提供的显示面板制造过程中的结构三示意图; 图 4为本发明实施例提供的显示面板制造过程中的结构四示意图; 图 5为本发明实施例提供的显示面板制造过程中的结构五示意图; 图 6为本发明实施例提供的显示面板制造过程中的结构六示意图; 以及 图 7为本发明实施例提供的一种显示面板结构示意图。 具体实施方式
为使本发明实施例的目的、 技术方案和优点更加清楚, 下面将结合本发 明实施例的附图,对本发明实施例的技术方案进行清楚、 完整地描述。显然, 所描述的实施例是本发明的一部分实施例, 而不是全部的实施例。 基于所描 述的本发明的实施例, 本领域普通技术人员在无需创造性劳动的前提下所获 得的所有其他实施例, 都属于本发明保护的范围。
本发明实施例提供的阵列基板的制造方法, 包括以下步骤:
S101、 在基板 1上形成像素单元层 2。
当然,根据现有技术,这里像素单元层可包括纵横交叉的栅线和数据线, 以及被数据线和栅线围成的像素单元。 像素单元包括开关元件, 开关元件一 般为薄膜场效应晶体管 (Thin Film Transistor, TFT )开关。 TFT开关包括: 源极、 漏极、 栅极和有源层。 在(扭曲向列) TN 的显示面板中, 该像素单 元层还包括与 TFT开关漏极相连的像素电极; 在(平面转换) IPS模式和边 缘场开关 (FFS )模式的显示面板中该像素单元层还包括公共电极层。 对于 根据本发明实施例的阵列基板对像素单元的结构没有特别限定, 可以使用任 何合适类型的像素结构。
此外, 该像素单元层还可包括一层覆盖在其上方的钝化层用来保护像素 单元层中的电学器件。
S102、 在像素单元层 2上形成第一光敏高分子层 50。
5103、 对第一光敏高分子层 50进行第一方向的摩擦取向。
结合图 1所示,该第一光敏高分子层 50包括光敏高分子材料和易挥发溶 剂。
其中可选的, 光敏高分子材料包括选自聚乙烯醇肉桂酸酯、 聚乙烯氧肉 桂酸乙酯、聚对亚苯基二丙烯酸酯、聚乙烯醇肉桂叉乙酸酯、二乙烯苯、 Ν,Ν- 亚曱基双丙烯酰胺、 双丙烯酸乙二醇酯和安息香酶酯中的至少一种; 易挥发 有机溶剂包括选自丙酮、 乙醇和环烷烃中的至少一种。
5104、 对第一光敏高分子层 50进行干燥和光照固化形成第一取向层 5。 结合图 2所示, 可选的,将阵列基板置于 80°C~100°C的环境中 4~6分钟 对第一光敏高分子层 50进行干燥, 以便挥发掉第一高敏光分子层 50中的易 挥发溶剂,然后釆用紫外线照射对第一光敏高分子层 50进行光固化进而形成 第一取向层 5。
5105、 在第一取向层 5上对应反射区的位置形成一层反射层 4, 所述反 射层 4的材质例如为金属。
如图 3所示, 可选的, 该反射层 4可以为金属铝, 此外反射层 4的面积 在显示面板的每个像素单元上占二分之一。
5106、 在第一取向层 5和反射层 4上形成第二光敏高分子层 60。
5107、 对第二光敏高分子层 60进行第二方向的摩擦取向。
结合图 4所示,该第二光敏高分子层 60包括光敏高分子材料和易挥发溶 剂; 其中可选的, 光敏高分子材料包括选在聚乙烯醇肉桂酸酯、 聚乙烯氧肉 桂酸乙酯、聚对亚苯基二丙烯酸酯、聚乙烯醇肉桂叉乙酸酯、二乙烯苯、 Ν,Ν- 亚曱基双丙烯酰胺、 双丙烯酸乙二醇酯和安息香酶酯中的至少一种; 易挥发 有机溶剂包括选自中的丙酮、 乙醇、 环烷烃至少一种。
此外, 可选的这里摩擦取向所釆用的第二方向可以与制作第一取向层 5 所选取的第一方向相同, 亦或根据需求釆取不同的取向方向。
S108、 对第二光敏高分子层 60进行干燥处理并通过掩模板对反射层 4 正上方的第二光敏高分子层 60进行光照固化处理形成第二取向层 6,得到阵 列基板;
结合图 5所示,可选的将阵列基板置于 80°C~100°C的环境中 4~6分钟对 第一光敏高分子层 50进行干燥, 以便挥发掉第一光敏高分子层 50中的易挥 发溶剂,然后釆用紫外线同过掩模板 70对位于金属反射层 4正上方的第二光 敏高分子层 60照射光固化, 形成第二取向层 6, 如图 6所示; 这里由于阵列 基板上的透射区的取向层和反射区的取向层分开进行摩擦取向, 因此避免了 釆用传统工艺的一次摩擦取向技术造成的第一取向层和第二取向层的阶梯交 界处的摩擦不良现象的发生。
另外, 在通过掩模板 70对反射层正上方的光敏高分子层进行光固化后, 还可包括将反射层之外的区域中的高分子材料层去除的步骤。 由于该区域的 高分子材料层未经受光照射, 因此没有被固化而可以容易地通过任何合适的 方法去除。 例如, 可以使用任何合适的溶剂将未经受光照射的部分去除。
S109、 将上述阵列基板与制作成型的彩膜基板对盒并注入液晶。
本发明的实施例提供的显示面板制造方法, 釆用光敏高分子材料制作取 向层, 摩擦取向工艺分步进行, 能够避免半透半反的液晶显示器的摩擦工艺 不良发生, 提高画面整体品质。
