Description

本发明涉及显示器制作领域， 尤其涉及一种显示面板的封框胶涂布方法 和显示面板。
液晶显示器 （Liquid Crystal Display, LCD) 包括阵列基板和彩膜基板， 液晶被封装在由阵列基板和彩膜基板通过对盒工艺形成的液晶盒内。 在进行 对盒工艺时， 在其中一块玻璃基板上滴入一定量液晶， 在另一块玻璃基板上 涂布环形封框胶， 在真空状态下利用高精度对准装置， 实现阵列基板和彩膜 基板的高精准贴合。
封框胶在 LCD中起到的最主要作用是密封液晶盒、防止液晶泄露或气体 进入液晶盒内， 封框胶的粘结强度是影响其密封性能的关键因素。 封框胶的 粘结强度与封框胶涂布宽度有关， 封框胶的宽度越宽， 则粘结强度越大， 反 之， 封框胶的宽度越窄， 粘结强度越小。
目前显示面板迸行封框胶涂布日寸， 一般采用均匀涂布方式， 显示面板上 涂布的封框胶宽度都一样， 一般为 1.2 mm左右， 部分精细化的封框胶宽度能 做到 0,7〜0,8 mm。 但实际上， 显示面板上不同区域对封框胶的粘结强度要求 是不同的， 例如显示面板的四边区域和四角区域对封框胶粘结强度要求是不 一样的， 四角区域相对于四边区域更容易导致剥离， 故四角区域需要的封框 胶的粘结强度要高于四边区域需要的封框胶的粘结强度。 另外阵列基板和彩 膜基板不齐平的边或角， 也比较容易受到外力作用产生阵列基板和彩膜基板 之间的剥离， 其对封框胶粘结强度要求也较高， 但阵列基板和彩膜基板齐平 的边或角， 不容易受到外力作用造成剥离， 其对封框胶粘结强度要求比较低。 故采用现有技术的相同宽度的封框胶涂布方法， 对不同粘结强度要求的区域 位置涂布相同宽度的封框胶， 会造成显示面板上某些粘结强度要求较高的区 域， 涂布的封框胶宽度过窄进而容易造成剥离， 而对于显示面板上某些粘结 强度要求较低的区域， 涂布的封框胶宽度过宽， 会造成封框胶的浪费。 本发明的目的是提供一种显示面板的封框胶涂布方法和显示面板， 以解 决现有的均匀涂布方法中封框胶涂布宽度过小造成显示面板剥离或者封框胶 涂布宽度过大造成封框胶浪费的问题。

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， 并 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做 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。
实施例一
本发明实施例一提供一种显示面板的封框胶涂布方法， 如图 1所示为本 发明实施例一提供的封框胶涂布方法的流程图， 包括：
SI01 : 根据显示面板上对封框胶粘结强度要求不同的子区域， 确定不同 的封框胶涂布子区域。
具体地， 显示面板上不同区域对封框胶的粘结强度要求是不同的， 例如 可按照如图 2 所示的方式测试显示面板上不同区域对封框胶的粘结强度要 求， 将待测试的显示面板 1放在测试设备平台 2上， 用设备压头 3对待测试 部位迸行顶压， 直到显示面板的两个基板剥离或断裂为止， 设备压头 3会自 动记录下剥离或断裂瞬间设备压头 3上的压力， 设备压头 3上的压力大小即 可以反映封框胶粘结强度， 粘结强度要求越高， 则剥离或断裂瞬间设备压头 3上的压力越大。
显示面板 1 上的四边区域和四角区域对粘结强度要求一般是不同的， 四 角区域由于最容易受外力作用产生剥离， 故四角区域的粘结强度要求一般高 于四边区域的粘结强度要求， 故根据不同粘结强度要求的子区域确定不同的 涂布子区域时， 可将涂布子区域划分为显示面板四边区域和显示面板四角区 域。 迸一步地， 显示面板四边区域内， 存在两基板对齐的区域以及两基板不 对齐的区域， 如图 3所示， 两基板不对齐的区域 4容易受到外力作用产生剥 离， 对封框胶粘结强度要求较高； 两基板对齐的区域 5不容易受到外力作用， 对封框胶粘结强度要求也相对较低； 故按照显示面板中四边区域中两基板对 齐的区域以及两基板不对齐的区域， 可将封框胶涂布子区域确定为齐平区域 和非齐平区域。
8102： 针对不同的封框胶涂布子区域， 分别确定每一封框胶涂布子区域 所需的封框胶涂布宽度。
具体地， 显示面板四角区域由于最容易受外力作用产生剥离， 故显示面 板四角区域的粘结强度要求一般高于显示面板四边区域的粘结强度要求， 而 封框胶涂布的宽度越大， 粘结强度越强， 故本发明实施例中可将显示面板四 角区域的封框胶涂布宽度设置为大于显示面板四边区域的封框胶涂布宽度。
进一步地， 显示面板四边区域中的非齐平区域相对于显示面板中的齐平 区域， 容易受到外力作用产生剥离， 故显示面板的非齐平区域相对于显示面 板的齐平区域， 对封框胶粘结强度要求更高， 故本发明实施例中可将显示面 板四边区域中的非齐平区域的封框胶涂布宽度设置为大于显示面板四边区域 中的齐平区域的封框胶涂布宽度。例如，现有的封框胶涂布宽度一般为 1.1〜1.3 u m, 本发明实施例中对于非齐平区域， 封框胶涂布宽度可以设 成 1.3〜1.5 rn, 对于齐平区域， 封框胶宽度可以设计为 0,9〜l .l m。
SI 03： 根据确定的每一封框胶涂布子区域所需的封框胶涂布宽度， 采用 封框胶涂布装置， 在各封框胶涂布子区域分别涂布所需宽度的封框胶。
具体地， 封框胶的涂布宽度与封框胶涂布装置进行封框胶涂布时的涂布 压力和涂布速度相关， 涂布压力越大、 涂布速度越慢， 则封框胶的涂布量就 越大， 在基板对盒后， 得到固化后的封框胶涂布宽度就越大。 因此， 本发明 实施例中在 S102 中确定了不同封框胶涂布子区域内所需的封框胶涂布宽度 后， 可根据所需的涂布宽度确定经过每一封框胶涂布子区域的涂布压力和涂 布速度， 并可根据封框胶涂布子区域确定封框胶涂布装置的涂布路径， 然后 按照确定的涂布路径， 在各封框胶涂布子区域内分别采用对应的涂布压力和 涂布速度， 涂布所需宽度的封框胶。
优选地，本发明实施例中 S101中确定的封框胶涂布子区域中可能存在一 些相对空间比较大的区域， 例如显示面板四角区域相对空间比较大， 而显示 面板四边区域中也有可能存在一些空间比较大的区域， 故本发明实施例中为 了进一步加强封框胶的粘结强度， 可在设定的封框胶涂布子区域内， 设计一 些封框胶涂布形状， 以加强封框胶的粘结强度， 然后根据设 i十的涂布形状， 采用封框胶涂布装置， 在设定的需要有设计的封框胶涂布形状的封框胶涂布 子区域内迸行封框胶的涂布。
迸一步优选地， 本发明实施例中可在显示面板四角区域内， 利用四角的 拐角空间， 将封框胶涂布形状设计为三角形， 如图 3所示， 当然也可以为其 它形状， 本发明实施例不做限定。
本发明实施例中， 还可在显示面板四边区域中一些空间比较大的区域内 设置一些加固点， 如图 4所示， 可在显示面板四边区域中具有长条形封框胶 涂布形状的长边方向的两侧设置一些加固点， 本发明实施例中加固点的形状 可优选方形或圆形， 并且加固点可设置为多个， 每两个加固点之间具有设定 的间距， 例如可以间隔 1〜5 mm设置一个加固点。
需要说明的是， 本发明实施例中封框胶涂布宽度、 显示面板四角区域封 框胶涂布形状、 大小、 加固点的形状、 尺寸以及分布， 可以根据产品空间和 需求迸行设 ， 本发明并不做限定。
本发明实施例提供的显示面板的封框胶涂布方法， 根据显示面板上对封 框胶粘结强度要求不同的子区域， 确定不同的封框胶涂布子区域， 并确定不 同的封框胶涂布子区域所需的封框胶涂布宽度， 在不同的封框胶涂布子区域 涂布不同宽度的封框胶， 能够在对封框胶粘结强度要求较高的区域涂布较宽 的封框胶， 避免造成封框胶涂布宽度过小造成基板剥离， 并且还可在粘结强 度要求较低的区域涂布较窄的封框胶， 避免封框胶的浪费。
进一步地， 本发明实施例中可根据显示面板中各区域的空间， 选择不同 的封框胶涂布形状， 以进一步加强封框胶的粘结强度。
实施例二
本发明实施例二提供一种显示面板， 如图 3所示， 该显示面板包括第一 基板 6和第二基板 7， 第一基板 6和第二基板 7相对设置， 第一基板 6和第 二基板 7的四周边缘设置有封框胶 8 , 该封框胶 8在显示面板上不同封框胶 粘结强度要求的子区域内对应有不同的涂布宽度。
优选地， 本发明实施例中显示面板上不同封框胶粘结强度要求的子区域 可包括显示面板四边区域和显示面板四角区域， 显示面板四角区域由于最容 易受外力作用产生剥离， 故显示面板四角区域的粘结强度要求一般高于显示 面板四边区域的粘结强度要求， 而封框胶涂布的宽度越大， 粘结强度越强， 故本发明实施例中可将显示面板四角区域的封框胶涂布宽度设置为大于显示 面板四边区域的封框胶涂布宽度， 参阅图 3所示。
进一步优选地， 本发明实施例中显示面板四边区域包括齐平区域和非齐 平区域， 显示面板四边区域中的非齐平区域相对于显示面板中的齐平区域， 更容易受到外力作用产生剥离， 故显示面板的非齐平区域相对于显示面板的 齐平区域对封框胶粘结强度要求更高， 故本发明实施例中可将显示面板四边 区域中的非齐平区域的封框胶涂布宽度设置为大于显示面板四边区域中的齐 平区域的封框胶涂布宽度， 可再次参阅图 3所示。 例如， 现有的封框胶涂布 宽度一般为 l. l〜1.3 m, 本发明实施例中对于非齐平区域， 封框胶涂布宽度 可以设 成 1.3〜1 ,5 μ m，对于齐平区域，封框胶宽度可以设 为 0,9〜1 , 1 μ m。
进一步优选地， 本发明实施例中可在显示面板四角区域内， 利用四角的 拐角空间， 将封框胶涂布形状设计为三角形， 如图 3所示， 当然也可以为其 它形状， 本发明实施例不做限定。
本发明实施例中， 还可在显示面板四边区域中一些空间比较大的区域内 设置一些加固点， 如图 4所示， 可在显示面板四边区域中具有长条形封框胶 涂布形状的长边方向的两侧设置方形加固点 9或圆形加固点 10， 本发明实施 例中加固点的形状优选方形或圆形， 并不引以为限， 并且加固点可设置为多 个， 每两个加固点之间具有设定的间距， 例如可以间隔 1〜5 mm设置一个加 固点。
需要说明的是， 本发明实施例中封框胶涂布宽度、 显示面板四角区域封 框胶涂布形状、 大小、 加固点的形状、 尺寸以及分布， 可以根据产品空间和 需求迸行设 ， 本发明并不做限定。
本发明实施例提供的显示面板， 对封框胶粘结强度要求不同的子区域内 设置有涂布宽度不同的封框胶， 对封框胶粘结强度要求较高的区域设置有涂 布宽带较大的封框胶， 避免由于封框胶涂布宽度过小造成两个基板剥离， 对 封框胶粘结强度要求较低的区域设置有涂布宽度较窄的封框胶， 避免封框胶 的浪费。
进一步地， 本发明实施例中可根据显示面板中各区域的空间， 选择不同 的封框胶涂布形状， 以进一步加强封框胶的粘结强度。
显然， 本领域的技术人员可以对本发明进行各种改动和变型而不脱离本 发明的精神和范围。 这样， 倘若本发明的这些修改和变型属于本发明权利要 求及其等同技术的范围之内， 则本发明也意图包含这些改动和变型在内。
