Description

基板、 液晶显示面板、 液晶显示装置及密封胶涂布方法
【技术领域】
本发明涉及液晶显示领域， 更具体的说， 涉及一种基板、 液晶显示面板、 液晶显示装置及密封胶涂布方法。
【背景技术】
液晶显示装置包括液晶面板， 液晶面板的生产都是在大面板组上按预定尺 寸进行切割形成， 大面板组由内含薄膜晶体管（TFT )的阵列基板和具有多个彩 色滤光片的滤光基板贴合而成， 贴合之前需要在其中一块基板上涂布密封胶 ( sealant ), 涂布形成若干个四边形区域， 该区域为液晶面板的显示区域， 形状 大小和所需切割的液晶面板的尺寸相适应， 在所述区域内滴注液晶， 然后将两 块基板进行热压贴合， 贴合后沿密封胶周边进行切割， 形成所需要尺寸的液晶 面板。 现有技术的涂布过程起始于显示区域的其中一条边框上， 涂布终止的时 候会越过起始位置， 形成交接区段， 以确保密封性。 由于加工精度难于控制， 交接区段上的胶量往往过多， 压合后， 容易有材料间相互污染的问题， 比如对 液晶的污染， 影响显示品质； 另外， 交接区段胶量过多而造成压合后所需的胶 材线宽难控制。
美国专利 US7,408,614公开了一种密封图形结构和及其形成方法， 如图 1 所示， 涂布的时候先从区域外开始涂布， 形成起始区段； 然后向内弯进显示区 域的一边开始正式的涂布作业， 终止的时候由内向外弯出延伸涂布， 形成终止 区段， 起始区段和终止区段交叉形成交接区段， 由于重叠面积小， 因此可以有 效防止交接区段堆积过量的密封胶， 但是该方法中起始区段和终止区段都是往 外弯曲， 因此交接区段会偏离所在的边框， 使得交接区段所在的边框宽度明显 大于显示区域其它三个边框的宽度， 仍然存在压合后所需的胶材线宽难控制的 问题； 另外交接区段在边框上， 裁剪的时候不容易把交接区段部位裁剪平整。 【发明内容】
本发明所要解决的技术问题是提供一种密封交接区段容易加工平整、 胶材 线宽容易控制的用于液晶显示面板的基板、 液晶显示面板、 液晶显示装置及加 工液晶显示装置时使用的密封方法。
本发明的目的是通过以下技术方案来实现的：
一种用于液晶显示面板的基板， 包括由密封胶包围形成的四边形显示区域， 所述显示区域周边的密封胶的起始端点和终止端点重叠形成交接区段， 其中所 述交接区段位于所述显示区域的角位置。
所述密封胶的起始端点和终止端点在所述角位置外继续延伸分别形成有起 始区段及终止区段， 所述起始区段和终止区段的重叠区域形成交接区段。 这样 的设计使得无需刻意控制涂布作业的精度， 可以在保证显示区域可靠密封的同 时， 也不会导致交接区段胶量过多。
所述起始区段和终止区段为互相垂直的直线段。
所述起始区段和终止区段为弧线段。
所述起始区段和终止区段向内弯曲的一侧相互对置。
所述起始区段和终止区段向外弯曲的一侧相互对置。
一种液晶显示面板， 包括基板， 所述的基板包括由密封胶包围形成的四边 形显示区域， 所述显示区域周边的密封胶的起始端点和终止端点重叠形成交接 区段， 其特征在于所述交接区段位于所述显示区域的角位置。
一种液晶显示装置， 所述的液晶显示装置使用了上述液晶显示面板。
一种加工液晶显示装置时使用的密封胶涂布方法， 包括以下步骤：
A、在要涂布的基板上预设的显示区域的其中一个角位置开始， 围绕显示区 域涂布密封胶， 并在角位置终止。
优选的， 所述步骤 A中涂布时从显示区域外开始， 然后抵达所述角位置， 形成起始区段； 涂布终止时回到所述角位置后继续往外延伸， 形成终止区段， 所述起始区段和终止区段的重叠区域形成交接区段。 无需刻意控制涂布作业的 精度， 可以在保证显示区域可靠密封的同时， 也不会导致交接区段胶量过多。 优选的， 所述步骤 A中， 所述起始区段和终止区段为互相垂直的直线段。 此为一种具体实施方式。
优选的， 所述步骤 A中， 所述起始区段和终止区段为弧线段。 此为另一种 具体实施方式。
优选的， 所述起始区段和终止区段向内弯曲的一侧相互对置。 此为一种具 体实施方式。
优选的， 所述起始区段和终止区段向外弯曲的一侧相互对置。 此为一种具 体实施方式。
本发明由于使密封胶的涂布接点刚好在角落上， 涂布接点刚好在角落上， 使得在进行裁切时便能直接将多余的密封胶材料一并裁切掉； 另外也可避免密 封胶在压合后， 因交接点涂布量过厚而造成材料的挤压污染， 并可减少多次切 割工时。 密封交接区段在显示区域的角位置， 不会偏离显示区域， 解决了线宽 难于控制的问题； 并且交接区段位于角位置， 在显示区域其中两条边框的交接 处， 在沿显示区域边框进行裁切的时候该交接区段可以接受两次切割， 提高了 交接区段的平整程度。

所述密封胶的起始端点和终止端点在所述角位置外继续延伸分别形成有起 始区段及终止区段， 所述起始区段和终止区段的重叠区域形成交接区段。 这样 的设计使得无需刻意控制涂布作业的精度， 可以在保证显示区域可靠密封的同 时， 也不会导致交接区段胶量过多， 延伸形成的起始区段及终止区段在后续的 裁切工序中会被切除。
上述加工液晶显示装置时使用的密封胶涂布方法， 包括以下步骤：
A、 在要涂布的基板上预设的显示区域的其中一个角位置开始， 围绕显示区 域涂布密封胶， 并在角位置终止。
下面选择阵列基板作为涂布基板为例子， 结合具体实施例进一步阐释所述液 晶显示装置的密封胶涂布方法：
实施例一： 如图 2和 3所示， 按所需液晶面板的尺寸在阵列基板上限定多个 显示区域， 然后从显示区域其中一个角位置开始进行密封胶涂布作业， 为了更 好地确保形成完整密封的显示区域， 可以选择在远离显示区域的位置开始涂布， 以直线方式从角位置进入显示区域的一边开始涂布作业， 涂布终止时从该角位 置直线延伸涂布到显示区域外。 涂布作业的起始位置和所述角位置之间形成起 始区段； 涂布作业的终止位置和所述角位置之间形成终止区段， 两者之间互相 垂直。 起始区段和终止区段在所述角位置处交叉， 形成所述的交接区段。 使用 时先将液晶注入所述显示区域， 然后再盖上滤光基板进行热贴合， 最后沿显示 区域边框进行切割形成所述液晶显示装置的面板。 切割时紧贴显示区域边框， 可以将密封胶的起始区段和终止区段一并切除， 无需额外增加切割工序就能得 到平整的液晶面板。
实施例二： 如图 2和 4所示， 按所需液晶面板的尺寸在阵列基板上限定多个 显示区域， 然后从显示区域其中一个角位置开始进行密封胶涂布作业， 为了更 好地确保形成完整密封的显示区域， 可以选择在远离显示区域的位置开始涂布， 以弧线方式从角位置进入显示区域的一边开始涂布作业， 涂布终止时从该角位 置以弧线方式延伸涂布到显示区域外。 涂布作业的起始位置和所述角位置之间 形成起始区段； 涂布作业的终止位置和所述角位置之间形成终止区段， 两者向 内弯曲的一侧相互对置。 起始区段和终止区段在所述角位置处交叉， 形成所述 的交接区段。 使用时先将液晶注入所述显示区域， 然后再盖上滤光基板进行热 贴合， 最后沿显示区域边框进行切割形成所述液晶显示装置的面板。 切割时紧 贴显示区域边框， 可以将密封胶的起始区段和终止区段一并切除， 无需额外增 加切割工序就能得到平整的液晶面板。
实施例三： 如图 2和 5所示， 按所需液晶面板的尺寸在阵列基板上限定多个 显示区域， 然后从显示区域其中一个角位置开始进行密封胶涂布作业， 为了更 好地确保形成完整密封的显示区域， 可以选择在远离显示区域的位置开始涂布， 以弧线方式从角位置进入显示区域的一边开始涂布作业， 涂布终止时从该角位 置以弧线方式延伸涂布到显示区域外。 涂布作业的起始位置和所述角位置之间 形成起始区段； 涂布作业的终止位置和所述角位置之间形成终止区段， 两者向 外弯曲的一侧相互对置。 起始区段和终止区段在所述角位置处交叉， 形成所述 的交接区段。 使用时先将液晶注入所述显示区域， 然后再盖上滤光基板进行热 贴合， 最后沿显示区域边框进行切割形成所述液晶显示装置的面板。 切割时紧 贴显示区域边框， 可以将密封胶的起始区段和终止区段一并切除， 无需额外增 加切割工序就能得到平整的液晶面板。
以上实施方式也可用在滤光基板上， 所述起始区段和终止区段的形状和相互 位置不局限于上述形式， 凡是涂布从显示区域外开始并从显示区域任意一个角 位置导入显示区域的一边进行涂布作业、 涂布终止时从该角位置延伸到显示区 域外的实施方案， 都在本发明的保护范围之内。 本发明由于涂布接点刚好在角 落上， 使得 cell裁切时便能直接将多余的 sealant材料一并裁切掉； 另外也可避 免 sealant在压合后， 因交接点涂布量过厚而造成材料的挤压污染。 并可减少多 次切割工时。 密封交接区段在显示区域的角位置， 不会偏离显示区域， 解决了 线宽难于控制的问题； 并且交接区段位于角位置， 在显示区域其中两条边框的 交接处， 在沿显示区域边框进行裁切的时候该交接区段可以接受两次切割， 提 高了交接区段的平整程度。
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。
