Description

显示面板的对盒方法 技术领域 本发明的实施例涉及显示技术领域， 尤其涉及显示面板的对盒 方法。 背景技术
随着显示技术的不断进步， 用户对显示装置的需求不断增加， TFT-LCD ( Thin Film Transistor-Liquid Crystal Display, 薄膜场效应晶体管液晶显示器） 凭借其低功耗、 低成本和无辐射等特点， 近年来更是得到了突飞猛进的发展。
在当前的液晶显示装置的成盒工艺中， 一般采用 ODF ( one drop filling, 快速滴注）工艺。 通常， ODF的工艺过程通过以下步骤实施： 在彩膜基板上 涂覆封框胶并在阵列基板上滴注液晶， 然后在对盒设备中对彩膜基板和阵列 基板进行对盒， 随后依次在紫外光照以及加热的条件下完成封框胶的固化。 在此 ODF工艺过程中，由于在彩膜基板的封框胶涂覆区域布置有黑矩阵 (以避 免周边发生漏光现象)， 因此紫外光通常是从阵列基板侧照射的， 并且， 需要 在紫外光源和阵列基板之间设置紫外光挡板， 以防止盒内的液晶受到紫外光 照射。
然而， 由于设计的需要， 在阵列基板的封框胶涂覆区域还设置有一些不 透明的金属线以及金属块， 这些不透明的金属线以及金属块会导致封框胶在 紫外光固化时的反应率较低。 发明内容
本发明的实施例提供了一种显示面板的对盒方法， 能够解决现有技术中 不透明的金属线以及金属块导致封框胶在紫外光固化时的反应率较低的问 题。
为达到上述目的， 本发明的实施例提供一种显示面板的对盒方法， 所述 显示面板包含第一基板和第二基板， 包括：
在所述第一基板的周边区域涂覆封框胶；
在所述第二基板上设置液晶； 对所述封框胶进行预固化处理；
在所述封框胶开始硬化前， 将所述第一基板和第二基板进行对盒， 使所 述第一基板涂覆有封框胶的一侧与所述第二基板设置有液晶的一侧相对。
所述封框胶为紫外光固化型封框胶。
所述封框胶的材料为丙烯酸脂类化合物。
所述对所述封框胶进行预固化处理的步骤包括：
利用紫外光对所述封框胶进行预固化处理。
所述紫外光的强度在 3000-lOOOOmJ/cm2的范围内。
所述紫外光的强度为 5000 mJ/cm2。
预固化所述封框胶所使用的紫外光的波长在 320nm至 380nm范围内。 预固化所述封框胶所使用的紫外光的波长在 330nm-340nm范围内。
所述对盒方法还包括：
对对盒后的所述第一基板及所述第二基板进行热处理。
热处理是在 100°C~140°C的温度范围内进行的。更进一步地，热处理是在 约 120 °C的温度下进行的。 热处理的持续时间为约 1小时。
本发明实施例所提供的显示面板的对盒方法， 包括在第一基板的周边区 域涂覆封框胶， 在第二基板上形成液晶， 对封框胶进行预固化处理， 在封框 胶开始硬化前， 将第一基板和第二基板进行对盒， 使第一基板涂覆有封框胶 的一侧与第二基板设置有液晶的一侧相对应。 由于对封框胶的预固化处理在 第一基板与第二基板对盒之前， 一方面， 该方法解决了现有技术中不透明的 金属线以及金属块导致封框胶在紫外光固化时反应率较低的问题， 另一方面， 该方法无需在紫外光源和阵列基板之间使用紫外光挡板以遮挡液晶， 筒化了 工艺步骤。 附图说明
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 筒单地介绍， 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为本发明提供的显示面板的对盒方法流程示意图；
图 2为本发明提供的显示面板的对盒方法的工艺流程示意图二； 以及 图 3为本发明提供的封框胶 E-200在紫外光固化处理过程中随时间的黏 度变化曲线。 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。
本发明实施例提供一种显示面板的对盒方法， 所述显示面板包含第一基 板和第二基板， 包括：
在所述第一基板的周边区域涂覆封框胶；
在所述第二基板上设置液晶；
对所述封框胶进行预固化处理；
在所述封框胶发生硬化反应前， 将所述第一基板和第二基板进行对盒， 使所述第一基板涂覆有封框胶的一侧与所述第二基板设置有液晶的一侧相 对。
图 1示出了本发明实施例提供的显示面板的对盒方法， 该方法包括： 步骤 S101、 制备第一基板和第二基板。
所述第一基板和所述第二基板的尺寸可以大于等于 10英寸。 这是由于， 10英寸以上的显示面板， 液晶能够在扩散了较长的时间后， 才接触到周边的 封框胶， 液晶与未固化封框胶接触时间短， 受到的污染较轻； 反之， 10英寸 以下的显示面板， 液晶扩散迅速接触到周边的封框胶， 液晶与未固化封框胶 接触时间长， 受到的污染可能较重。
步骤 S102、 在第一基板的周边区域涂覆封框胶。
在第一基板的周边区域涂覆封框胶， 这里所说的周边区域对应于显示面 板的非显示区域。 这里所说的涂覆， 指的是以任何方式将封框胶附着在基板 上。
例如， 所述封框胶可以采用紫外光固化型封框胶。
例如， 所述封框胶的材料可以为丙烯酸脂类化合物。
需要说明的是， 在本发明实施例中， 将封框胶涂覆在第一基板上为常用 方案。 还可以将封框胶涂覆于第二基板上。 本发明实施例并不做限制。 但是 不能将液晶和封框胶都布置在同一基板上。
步骤 S103、 对所述封框胶进行预固化处理。 例如， 利用紫外光进行预固 化处理。
所述预固化处理指的是利用紫外光对封框胶进行活性化， 在该预固化处 理过程中， 封框胶处于流体状态或胶状态的未开始固化状态， 并具有粘合性。 如图 3所示， 在涂覆光刻胶之后， 光刻胶处于流体状态或胶状态， 此时其反 应率较低， 对光刻胶进行预固化处理， 采用紫外光对光刻胶进行照射， 从图 上可以看到， 在照射过程中， 光刻胶的反应率逐渐增大， 但在开始照射的一 段时间内， 光刻胶仍然处于流体状态或胶状态， 并具有粘合性。 在光刻胶被 紫外光照射 5至 7分钟后， 光刻胶的反应率有一个很大的提升。 此时， 光刻 胶开始硬化， 快速进入固体状态， 并失去粘合性。
对所述光刻胶进行预固化的紫外光的强度可以在 3000-lOOOOmJ/cm2的范 围内。 例如， 所述紫外光的强度可以为 5000 mJ/cm2。
对所述光刻胶进行预固化的紫外光的波长可以在 320nm至 380nm的范围 内。 进一步地， 紫外光的波长在 330nm~340nm的范围内， 该波段紫外光对封 框胶的固化效果较好。
步骤 S104、 在第二基板上设置液晶。
例如， 以滴注的方式在第二基板上设置液晶。
在本发明实施例中， 步骤 S104可以与步骤 S102、 步骤 S103同时执行， 以保证后续第一基板能够在封框胶开始硬化前与设置有液晶的第二基板进行 对盒。
步骤 S105、 在所述封框胶开始硬化前， 将所述第一基板和第二基板进行 对盒， 使第一基板涂覆有封框胶的一侧与所述第二基板设置有液晶的一侧相 对。 如图 2所示。
液态的封框胶在受到紫外光预固化处理一段时间之后开始硬化， 如图 3 所示的开始硬化的时间点。 上述的在所述封框胶开始硬化前， 指的就是在用 紫外光对封框胶进行预固化之后， 在图 3所示的开始硬化的时间之前。 因此， 上述的步骤 S105需要在所述封框胶发生硬化反应前执行。 通常， 封框胶会在 紫外光照射后 5-7min开始迅速硬化， 因此需要在接受紫外光照后 5min以内 将两块基板进行对盒。
进一步地， 上述对盒方法还包括： 步骤 S106、 对对盒后的所述第一基板及所述第二基板进行加热处理。 需要说明的是， 步骤 S106中加热的目的是固化封框胶中的环氧组分， 使 封才 胶固化。 例如， 对基板的加热 40分钟以上， 再例如， 加热时间为 1个小 时； 加热温度的范围在 100°C~140°C , 再例如， 加热温度为 120°C。 这样使封 框胶完全固化。
下面， 通过具体示例， 分别对本发明实施例提供的显示面板的对盒方法 进行说明。
首先， 进行材料准备： 准备 4块 0.7mm厚、 25cm*25cm的玻璃基板， 在 其中 2块玻璃基板的距离玻璃基板边缘 5cm处的封框胶区域（封框胶区域的 宽度为约 lOOum )设置遮光的铬黑矩阵（Cr-black matrix, Cr-BM), Cr-BM的 宽度为 lOOum, 相邻 Cr-BM之间的间隔为 50um, 该表面处理用于模拟真实 阵列基板表面的不透明金属线或金属块。 使用的封框胶是日本积水（Sekisui ) 公司提供的 E-200。
如图 2所示， 本发明实施例的显示面板的对盒方法的流程为： 在设置有 Cr-BM的玻璃基板的中心位置上滴注液晶 0.2mL, 并在未设置有 Cr-BM的玻 璃基板上距离该玻璃基板边缘 5cm处涂覆宽 1mm的封框胶 E-200; 完成后， 将涂覆有封框胶的玻璃基板进行紫外光预固化处理， 由于没有液晶， 因此在 此过程中无需紫外光挡板，紫外光照射强度为 5000mJ/cm2;如图 3所示，Ε-200 在受到紫外光预固化处理 5-7min后开始硬化， 故需在涂覆有封框胶的玻璃基 板接受紫外光预固化处理 5min以内将两块玻璃基板进行对盒，控制涂覆有封 框胶的玻璃基板在接受紫外光预固化 3min后与另一块滴注有液晶的玻璃基板 进行对盒（此时，从液晶滴注工艺完成到开始对盒的时间需不超过 30min, 这 是由于， 若超过 30min, 液晶会扩散到显示面板边缘， 与未完全固化的封框胶 长时间接触， 液晶污染较重)； 对盒工艺可以持续 2min至 3min, 以保证对盒 完成后封框胶固化完毕； 之后对对盒后的基板进行加热， 加热温度为 120°C , 加热时间为 1 小时。 这样对盒形成的显示面板中的封框胶的反应率提高、 封 框胶对液晶的污染减小， 并且不使用额外的紫外光挡板， 节约了成本。
综上所述， 本发明实施例的显示面板的对盒方法， 有以下优点： 1 , 无需 使用遮挡液晶所用的紫外光挡板， 节约了成本； 2, 无需保持阵列基板在靠近 紫外光光源的一侧， 筒化了工艺； 3 , 解决了现有技术中不透明的金属线以及 金属块导致封框胶在进行紫外光固化时的反应率较低的问题。 另外， 还可以 通过控制紫外光照射时间和对盒时间， 在液晶没有大面积扩散到基板边缘并 与封框胶接触之前， 完成封框胶的固化， 这样减小封框胶对液晶的污染。
本发明实施例所提供的显示面板的对盒方法， 包括在第一基板的周边区 域形成封框胶， 在第二基板上形成液晶， 对封框胶进行预固化处理， 在封框 胶开始硬化前将第一基板和第二基板进行对盒， 其中， 第一基板形成有封框 胶的一侧与第二基板形成有液晶的一侧相对应。 由于将封框胶的预固化处理 设置在第一基板与第二基板对盒之前， 一方面， 该技术方案解决了现有技术 中不透明的金属线以及金属块导致封框胶在进行紫外光固化时的反应率较低 的问题， 另一方面， 无需在紫外光源和阵列基板之间使用紫外光挡板以遮挡 液晶， 提高了封框胶的反应率， 筒化了工艺步骤。
本发明实施例还提供了一种显示面板， 该显示面板为采用上述显示面板 的对盒方法所制成的显示面板， 该显示面板的对盒方法与上述实施例完全相 同， 此处不再赘述。
本发明实施例还提供了一种显示装置， 具有上述实施例所描述的任意特 征的显示面板。 该显示装置可以为液晶显示装置， 包括相对平行设置的彩膜 基板和阵列基板， 以及填充于所述彩膜基板和阵列基板之间的液晶。
本发明实施例提供的液晶显示装置， 所述液晶显示装置可以为液晶显示 器、 液晶电视、 数码相框、 手机、 平板电脑等具有显示功能的产品或者部件， 本发明对此不做限制。
以上所述仅是本发明的示范性实施方式， 而非用于限制本发明的保护范 围， 本发明的保护范围由所附的权利要求确定。
