Description

对盒后的母板及其制作方法、 液晶显示面板及其制作方法 技术领域
本发明的实施例涉及一种对盒后的母板及其制作方法、 以及液晶显示面 板及其制作方法。 背景技术
液晶盒主要由对向基板、 阵列基板以及位于该两基板之间的液晶分子组 成。 在实际的液晶盒的制作过程中, 首先在两张母板上分别对应制作呈矩阵 排列的多个对向基板区域和多个阵列基板区域, 然后在两张母板之间涂覆封 框胶, 并进行对盒工艺, 最后分别沿各对向基板区域和各阵列基板区域对两 张母板进行切割, 形成多个小的液晶盒。
如图 la和图 lb所示, 对盒后的母板包括相对而置的第一母板 101和第 二母板 102; 在第一母板 101和第二母板 102之间设置有呈矩阵排列的多个 液晶盒 103, 每个液晶盒 103均具有显示区域 104和非显示区域。 在第一母 板 101和第二母板 102之间, 在每个液晶盒 103中的非显示区域涂覆有第一 封框胶 105,第一封框胶 105用于支撑第一母板 101和第二母板 102,并有效 地密封填充在两个母板之间的液晶分子。 在第一母板 101和第二母板 102之 间, 在呈矩阵排列的液晶盒 103以外的边缘区域涂覆有第二封框胶 106, 第 二封框胶 106仅在对盒后的切割工艺中起到支撑第一母板 101 和第二母板 102的作用, 在将对盒后的母板切割成多个液晶盒后, 第二封框胶 106所在 的母板区域会被切除。
在对上述对盒后的母板进行切割工艺时, 两个母板受到挤压会使封框胶 容易发生形变, 由于封框胶的弹性较弱, 其产生的形变较难恢复, 这样会导 致最后形成的液晶盒的盒厚不均匀, 进而产生显示亮度不均匀的问题, 影响 显示口口/贝。
因此, 如何有效避免在切割对盒后的母板时引起的液晶盒的盒厚不均匀 的问题, 是本领域技术人员亟需解决的问题。 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 la和图 lb分别为现有技术中对盒后的母板的侧视图和俯视图; 图 3为本发明实施例提供的对盒后的母板的俯视图; 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。
附图中各膜层的形状和厚度不反映真实比例, 目的只是示意说明本发明 实施例的内容。
本发明实施例提供的一种对盒后的母板, 如图 2a和图 2b所示, 包括: 相对而置的第一母板 1和第二母板 2; 在第一母板 1和第二母板 2之间设置 有呈矩阵排列的多个具有显示区域 3的液晶盒 4,在第一母板 1和第二母板 2 之间具有包围各液晶盒 4的显示区域 3的边界闭合的第一封框胶 5, 在第一 母板 1与第二母板 2之间具有包围呈矩阵排列的液晶盒 4所在区域的边界闭 合的第二封框胶 6;
如图 2a所示, 在第一母板 1与第一封框胶 5和 /或第二封框胶 6的接触 处设置有具有弹性的第一弹性部件 7; 和 /或如图 2b所示, 在第二母板 2与 第一封框胶 5和 /或第二封框胶 6的接触处设置有具有弹性的第二弹性部件 8。 作为示例,图 2a中示出了在第一母板 1与第一封框胶 5和第二封框胶 6的接 触处均设置有第一弹性部件 7。 作为示例, 图 2b中示出了在第二母板 2与第 一封框胶 5和第二封框胶 6的接触处均设置有第二弹性部件 8。
本发明实施例提供的上述对盒后的母板, 由于在第一母板 1与第一封框 胶 5和 /或第二封框胶 6的接触处增加第一弹性部件 7, 和 /或, 在第二母板 2 与第一封框胶 5和 /或第二封框胶 6的接触处增加第二弹性部件 8, 在切割对 盒后的母板时, 由于增加的弹性部件具有一定的弹性, 因此可以避免由于封 胶弹性不足使其产生的形变不能恢复, 而导致的液晶盒的盒厚不均匀的问 题, 从而避免制作出的液晶盒显示亮度不均匀的问题, 改善了显示品质; 并 且, 在封框胶的对应区域增加弹性部件还能减少封框胶的用量, 降低生产成 本。
例如, 为了保证增加的弹性部件具有较好的弹性性能, 在本发明实施例 提供的上述母板中, 如图 2a和图 2b所示, 可以将第一弹性部件 7的材料设 置为与位于液晶盒 4内的隔垫物 9的材料相同, 将第二弹性部件 8的材料设 置为与位于液晶盒 4内的隔垫物 9的材料相同。 这是由于形成隔垫物 9的材 料具有较好的弹性和强度, 其对环境的污染较小, 并且, 釆用形成隔垫物 9 的材料制作弹性部件, 工艺上也容易实现。 当然, 也可以釆用其他具有较好 弹性性能的材料制作弹性部件, 在此不做限定。
在具体实施时, 新增的弹性部件的设置可以有很多种情况。 例如, 可以 仅在第一母板 1与第一封框胶 5的接触处设置第一弹性部件 7; 也可以仅在 第一母板 1与第二封框胶 6的接触处设置第一弹性部件 7; 也可以仅在第二 母板 2与第一封框胶 5的接触处设置第二弹性部件 8;也可以仅在第二母板 2 与第二封框胶 6的接触处设置第二弹性部件 8; 还可以将上述情况任意组合 进行设置, 在此不做限定。
在本发明实施例提供的上述母板中, 在第一母板 1与第一封框胶 5的接 触处设置第一弹性部件 7, 同时在第二母板 2与第一封框胶 5的接触处设置 第二弹性部件 8, 这样可能会存在由于第一封框胶 5的厚度过薄所导致的断 胶问题, 进而产生液晶分子泄露等不良。 虽然通过减小第一弹性部件 7和第 二弹性部件 8的厚度可以避免断胶问题的发生, 但是第一弹性部件 7和第二 弹性部件 8的厚度过薄又会减弱其弹性性能。 因此, 在第一母板 1与第一封 框胶 5的接触处设置第一弹性部件 7并同时在第二母板 2与第一封框胶 5的 接触处设置第二弹性部件 8的情形下,需要对第一弹性部件 7、第一封框胶 5 及第二弹性部件 8的厚度进行适当的选择, 以避免上述问题。
例如, 在本发明实施例提供的上述母板中, 可以在形成有隔垫物 9的母 板一侧形成弹性部件, 这是由于在常规的液晶盒结构中, 隔垫物 9一般设置 在对向基板一侧, 设置在对向基板一侧的诸如彩色滤光片等膜层的材料一般 为高分子材料, 而弹性部件一般釆用和隔垫物 9相同的材料, 一般也为高分 子材料, 那么将弹性部件与隔垫物 9制作在相同的母板上, 可以使弹性部件 更好地粘附于母板上, 防止弹性部件从母板上脱落。
例如, 为了避免增加额外的制作工艺, 在本发明实施例提供的上述母板 中,在第一母板 1面向第二母板 2的一侧设置每个液晶盒 4内的隔垫物 9时, 第一弹性部件 7可以与隔垫物 9同层设置, 即釆用一次构图工艺同时形成隔 垫物 9和第一弹性部件 7, 这样不需要增加新的掩模板, 不会增加制作工艺, 进而不会降低生产效率。
当然, 也可以在第二母板 2面向第一母板 1的一侧设置每个液晶盒 4内 的隔垫物 9, 此时, 第二弹性部件 8可以与隔垫物 9同层设置, 即釆用一次 构图工艺同时形成隔垫物 9和第二弹性部件 8, 这样也不需要增加新的掩模 板, 不会增加制作工艺, 进而不会降低生产效率。
例如, 为了保证第一封框胶 5和第二封框胶 6的厚度适中以避免断胶问 题, 以及考虑第一弹性部件 7和第二弹性部件 8的制作工艺, 在本发明实施 例提供的上述母板中, 第一封框胶 5沿垂直于第一母板 1和第二母板 2方向 的第一厚度与液晶盒 4沿垂直于第一母板 1和第二母板 2方向的盒厚之比为 1 : 1.2-1 : 2, 第二封框胶 6沿垂直于第一母板 1和第二母板 2方向的第二厚 度与液晶盒 4沿垂直于第一母板 1和第二母板 2方向的盒厚之比为 1 : 1.2-1 : 2。
进一步地, 例如在本发明实施例提供的上述母板中, 第一封框胶 5沿垂 直于第一母板 1和第二母板 2方向的第一厚度与液晶盒 4的盒厚之比为 1 : 1.5,第二封框胶 6沿垂直于第一母板 1和第二母板 2方向的第二厚度与液晶 盒 4的盒厚之比为 1 : 1.5。
例如, 为了使弹性部件与封框胶接触均匀, 以避免断胶问题, 在本发明 实施例提供的上述母板中, 可以将在第一母板 1与第一封框胶 5的接触处设 置的第一弹性部件 7与第一封框胶 5的接触面设置为平面, 在第一母板 1与 第二封框胶 6的接触处设置的第一弹性部件 7与第二封框胶 6的接触面为平 面, 在第二母板 2与第一封框胶 5的接触处设置的第二弹性部件 8与第一封 框胶 5的接触面为平面, 在第二母板 2与第二封框胶 6的接触处设置的第二 弹性部件 8与第二封框胶 6的接触面为平面。
当然, 也可以根据实际需要对上述接触面进行构图工艺, 这样可以增大 弹性部件与封框胶的接触面积。 由根据本发明实施例的对盒后的母板切割成的液晶盒 4可以应用于高级 超维场开关(ADS )型液晶显示屏或平面内开关(IPS )型液晶显示屏, 即像 素电极和公共电极都位于阵列基板面向液晶层的一侧; 也可以应用于扭转向 歹 |J ( TN )型液晶显示屏或垂直排列 (VA )型液晶显示屏, 即像素电极位于 阵列基板面向液晶层的一侧, 公共电极位于对向基板面向液晶层的一侧, 在 此不作限定。
在本发明实施例提供的上述母板切割后得到的液晶盒 4应用于 TN型液 晶显示屏或 VA型液晶显示屏时, 在每个液晶盒 4中公共电极与像素电极分 别位于第一母板 1和第二母板 2,即公共电极位于第一母板 1面向第二母板 2 的一侧, 像素电极位于第二母板 2面向第一母板 1的一侧; 或者, 像素电极 位于第一母板 1面向第二母板 2的一侧, 公共电极位于第二母板 2面向第一 母板 1的一侧。 该类液晶显示屏需要电性导通第一母板 1与第二母板 2, 如 图 3所示, 可以在第一母板 1和第二母板 2之间且位于液晶盒 4的显示区域 3以外的区域设置至少一个第三封框胶 10, 这样第一母板 1通过第三封框胶 10可以实现与第二母板 2电性连接。
进一步地, 由于形成第一弹性部件 7和第二弹性部件 8的材料均为绝缘 材料, 因此,上述第三封框胶 10的设置尤其适用于在第一母板 1与第一封框 胶 5的接触处设置有第一弹性部件 7, 和 /或, 在第二母板 2与第一封框胶 5 的接触处设置有第二弹性部件 8的情况。
当然, 也可以釆用在第一弹性部件 7和第二弹性部件 8中加入导电球的 方式, 以使他们具有导电性能, 省去设置第三封框胶 10, 来达到电性导通第 一母板 1和第二母板 2的效果, 在此不做限定。
此外, 在本发明实施例提供的上述母板切割后得到的液晶盒 4应用于 ADS型液晶显示屏或 IPS型液晶显示屏时, 由于公共电极和像素电极均位于 第一母板 1面向第二母板 2的一侧, 或者, 公共电极和像素电极均位于第二 母板 2面向第一母板 1的一侧, 因此, 该类液晶显示屏不需要电性导通第一 母板 1与第二母板 2, 这样也可以不需要在第一母板 1和第二母板 2之间且 位于液晶盒 4的显示区域 3以外的区域设置第三封框胶 10。 还提供了一种对盒后的母板的制作方法, 具体步骤可以包括: ( 1 )、在第一母板上形成呈矩阵排列的多个具有显示区域的对向基板的 图形, 在第二母板上对应形成呈矩阵排列的多个具有显示区域的阵列基板的 图形;
需要说明的是, 在第一母板上形成对向基板的图形与在第二母板上形成 阵列基板的图形没有先后顺序, 在此不做限定。
( 2 )、在第一母板或第二母板上形成包围各显示区域的边界闭合的第一 封框胶; 在第一母板上形成包围呈矩阵排列的对向基板的图形所在区域的边 界闭合的第二封框胶, 或在第二母板上形成包围呈矩阵排列的阵列基板的图 形所在区域的边界闭合的第二封框胶;

例如, 为了避免增加额外的制作工艺, 本发明实施例提供的上述方法在 具体实施时, 由于隔垫物设置在第一母板面向第二母板的一侧, 因此, 在第 一母板上形成与第一封框胶的涂覆区域对应的和 /或与第二封框胶的涂覆区 域对应的第一弹性部件的图形, 可以包括: 釆用一次构图工艺, 在形成各对 向基板的图形中的隔垫物图形的同时形成第一弹性部件的图形, 即第一弹性 部件与隔垫物同层设置, 这样不需要增加新的掩膜板, 不会增加制作工艺, 不会降低生产效率。
