图 1是本发明实施例所提供的显示面板母版的结构示意图。
图 2是本发明实施例所提供的显示面板的结构示意图。
图 3是本发明实施例所提供的显示面板加工方法的步骤流程图。
具体实施方式
下面将结合本发明实施例中的附图， 对本发明实施例中的技术方案进行清 楚、 完整地描述， 显然， 所描述的实施例仅仅是本发明一部分实施例， 而不是 全部的实施例。 基于本发明中的实施例， 本领域普通技术人员在没有作出创造 性劳动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。 如图 1所示， 本发明实施例所提供的显示面板母版 1包括第一基板 10、 第 二基板 12及设置在所述第一基板 10与第二基板 12之间的液晶分子 14。所述第 一基板 10与第二基板 12上分别包括相互对应的显示区域 A及非显示区域 B。 所述第一基板 (10)及第二基板 (12)中的至少一个的非显示区域 B包括与所述显示 区域 A相邻的有效部 C及位于有效部 C外侧的切割部 D。 所述液晶分子 14通 过封装体 16密封在第一基板 10与第二基板 12的显示区域 A内。所述第一基板 10及第二基板 12的显示区域 A上设置有电极 18。所述第一基板 10及第二基板 12中的至少一个的非显示区域 B设置有用于控制电极 18所施加电压的控制电路 19及设置在切割部 D上所述控制电路 19的外接端子 19a。 所述第一基板 10及 第二基板 12中的至少一个的非显示区域 B上对应所述控制电路 19的位置设置 有绝缘膜图案 17。 所述外接端子 19a处不设置绝缘膜图案 17。 所述第一基板 10 及第二基板 12 选自薄膜晶体管 (Thin Film Transistor, TFT)基板及彩色滤光片 (Color Filter, CF)基板中的一个。 所述控制电路 19可全部设置在有效部 C, 也可 以一部分设置在有效部 C而另一部分设置在切割部 D上。 在本实施例中， 所述 第一基板 10为 TFT基板。 所述第二基板 12为 CF基板。 所述控制电路 19全部 设置在所述有效部 C。
所述控制电路 19用于根据所接收的显示信号来控制施加至显示区域 A内的 电极 18上的电压， 以调节液晶分子 14的转向而达到调制光线实现图像显示的 效果。在本实施例中，所述第一基板 10的非显示区域 B上所设置的控制电路 19 为固化电路。所述第一基板 10的显示区域 A上所设置的电极 18为像素电极 18a。 所述像素电极 18a与位于非显示区域 B内的固化电路 19电连接。 所述固化电路 19用于在对液晶分子 14进行光配向时通过像素电极 18a对液晶分子 14施加预 设电压以对液晶分子 14的配向进行固定。
所述第二基板 12上所设置的电极 18为公共电极 18b。所述公共电极 18b覆 盖所述第二基板 12的显示区域 A与非显示区域 B。所述公共电极 18b用于提供 一相同的电位， 以与所述第一基板 10上对应的像素电极 18a形成电场以控制所 述液晶分子 14的转动。
在本实施例中，所述非显示区域 B内对应所述固化电路 19的位置处所设置 的有绝缘膜图案 17为高分子聚合的光配向膜， 材料为聚酰亚胺 (Polyimide)。
因为所述绝缘膜图案 17绝缘防电， 所以即使在显示面板的生产过程中会有 金属粒子或其他导电性杂质 2散落在固化电路上也会被绝缘的绝缘膜图案 17所 阻挡而不会与其他电路或端口导通而导致短路。
可以理解的是， 所述绝缘膜图案 17还可以设置在所述第一基板 10的非显 示区域 B上或者同时设置在第一基板 10及第二基板 12的非显示区域 B上。
如图 2所示， 本发明实施例所提供的显示面板 3的结构与所述显示面板母 版 1基本相同， 其区别在于： 所述显示面板 3的第一基板 10与第二基板 12的 非显示区域 B的切割部 D在完成光配向后被切除。 即， 形成在所述切割部 D上 的控制电路 19的外接端子 19a或部分控制电路 19被切掉。 所述第一基板 10及 第二基板 12中的至少一个的非显示区域 B设置有切割后所残余的用于控制所述 电极 18上所施加电压的控制线路， 所述第一基板 10及第二基板 12中的至少一 个的非显示区域 B上对应残余的所述控制线路的位置处设置有绝缘膜图案 17。
如图 3所示， 本发明实施例所提供的显示面板的加工方法， 其包括： 步骤 S11 , 提供平行相对的第一基板 10及第二基板 12, 所述第一基板 10 与第二基板 12上分别包括相互对应的显示区域 A及非显示区域 B, 所述非显示 区域 B包括与所述显示区域 A相邻的有效部 C及位于有效部 C外侧的切割部 D。
所述第一基板 10及第二基板 12选自薄膜晶体管 (Thin Film Transistor, TFT) 基板及彩色滤光片（Color Filter, CF)基板中的一个。 所述控制电路 19可全部设置 在有效部 C, 也可以一部分设置在有效部 C而另一部分设置在切割部 D上。 在 本实施例中， 所述第一基板 10为 TFT基板。 所述第二基板 12为 CF基板。 所 述控制电路 19全部设置在所述有效部 C。
步骤 S12,在所述第一基板 10及第二基板 12的显示区域 A上设置电极 18。 在本实施例中， 所述第一基板 10的显示区域 A上所设置的电极 18为像素电极 18a。 所述像素电极 18a与位于非显示区域 B内的控制电路 19电连接。 所述控 制电路 19控制施加于所述像素电极 18a上的电压。 所述第二基板 12上所设置 的电极 18为公共电极 18b。所述公共电极 18b覆盖所述第二基板 12的显示区域 A与非显示区域 B。所述公共电极 18b用于提供一相同的电位， 以与所述第一基 板 10上对应的像素电极 18a形成电场以控制所述液晶分子 14的转动。
步骤 S13 , 在所述第一基板 10及第二基板 12中至少一个的非显示区域 B 上设置用于控制所述电极 18上所施加电压的控制电路 19及在切割部 D上设置 所述控制电路 19的外接端子 19a。所述控制电路 19用于根据所接收的显示信号 来控制施加至显示区域 A内的电极 18上的电压， 以调节液晶分子 14的转向而 达到调制光线实现图像显示的效果。
在本实施例中， 所述第一基板 10的非显示区域 B上所设置的控制电路 19 为固化电路。所述固化电路用于在对液晶分子 14进行光配向时通过像素电极 18a 对液晶分子 14施加预设电压以对液晶分子 14的配向进行固定。
步骤 S14,在所述第一基板 10及第二基板 12中的至少一个的非显示区域 B 上对应所述控制电路 19的位置处设置绝缘膜图案。 在本实施例中， 所述非显示 区域 B内对应所述固化电路 19的位置处所设置的有绝缘膜图案 17为高分子聚 合的光配向膜， 材料为聚酰亚胺 (Polyimide)。
因为所述绝缘膜图案 17绝缘防电， 所以即使在显示面板的生产过程中会有 金属粒子或其他导电性杂质 2散落在固化电路上也会被绝缘的绝缘膜图案 17所 阻挡而不会与其他电路或端口导通而导致短路。
步骤 S15, 通过封装体 16将液晶分子 14密封在所述第一基板 10与第二基 板 12的显示区域 A之间。
步骤 S16, 通过控制电路 19向所述电极 18施加预定电压以对液晶分子 14 进行光配向。
步骤 S17, 将所述第一基板 10及第二基板 12的切割部 D切除， 以获得显 示面板 3。
以上所揭露的仅为本发明一种较佳实施例而已， 当然不能以此来限定本发 明之权利范围， 因此依本发明权利要求所作的等同变化， 仍属本发明所涵盖的 范围。
