为使本发明的实施例的目的、 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的实施例的技术方案进行清楚、 完整的描述。 显 然, 所描述的实施例仅是本发明的一部分示例性实施例, 而不是全部的实施 例。 基于所描述的本发明的示例性实施例, 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它实施例都属于本发明的保护范围。

本发明实施例提供了一种封装方法, 如图 1-3所示, 所述封装方法包 括步骤:
S01、 在第一基板 10的封装区域 10a形成如图 3所示的玻璃胶 30图 案层。 虽然图中仅显示出图案中的一个单独封装区,但是整个图案可以包 含多个这样的单独封装区。
502、 结合图 3和图 4所示, 将形成有所述玻璃胶 30的第一基板(也 可称为封装基板)和同样具有封装区的第二基板 20 (因其上设置有待封 装器件, 因此也可称为器件基板)贴合, 使所述封装基板的所述封装区域 10a与所述器件基板的封装区域 10a对位。
例如, 第一和第二基板 10, 20均可为玻璃基板, 也可为其他材质基 板, 例如石英, 塑料等。
第二基板 20上设置有一个或多个待封装器件, 所述一个或多个待封 装器件位于所述第二基板上形成的封装区围成的一个或多个空间中。
503、 如图 5和图 6所示, 通过对所述封装区域进行激光 40照射, 对所述玻璃胶 30进行烧结,并在所述激光 40照射的同时,对所述封装区 域施加均匀的压合力 50。
当所述玻璃胶 30经过烧结并经冷却后, 可在所述封装基板与所述器 件基板之间形成固化的封装玻璃, 由于玻璃具有良好的隔离作用,从而可 以将所述器件基板中待封装器件密闭起来。
需要说明的是,本领域相关技术人员应当明白,所述器件基板的封装 区域 10a与所述器件基板的待封装的器件位于所述器件基板的同一面上。
对于上述步骤 S02 中的对位, 是指当所述封装基板的封装区域 10a 与所述器件基板的封装区域 10a面对面准确贴合后,使所述封装基板的封 装区域 10a与所述器件基板的封装区域 10a垂直对应, 这样, 在所述封装 基板与所述器件基板之间的空间内便形成了一个将所述器件基板的待封 装器件包围住的封装区域。
在本发明实施例中,所述封装基板的作用是与所述器件基板之间形成 一个密闭空间,以使所述器件基板中的待封装器件与周围环境隔绝。因此, 本领域相关技术人员应该明白, 对于整体母板而言, 所述玻璃胶 30的图 案是一个具有镂空部分的图案, 其中待封装器件位于所述玻璃胶 30的图 案中的镂空部分, 也即, 玻璃胶 30与第一基板 10和第二基板 20形成多 个中空的空间,位于第二基板 20上的待封装器件 21位于该中空的空间中。
考虑到所述玻璃胶 30在所述步骤 S03中的激光烧结过程中会有适量 的体积收缩, 而所述玻璃胶 30需使所述封装基板与所述器件基板之间形 成密闭的空间, 因此, 所述玻璃胶 30图案层的厚度需略大于所述器件基 板待封装器件的厚度, 并且, 所述玻璃胶 30图案层中的镂空部分的面积 应大于所述待封装器件图案的面积。该空间的尺寸可以根据实际情况进行 设定,以能够实现对所述待封装器件的封装且不影响所述待封装器件的其 他性能为准。
在所述步骤 S03中, 对所述封装区域进行激光 40照射可以釆用以下 方式:从所述封装基板的一侧对所述封装区域进行照射,或从所述器件基 板的一侧对所述封装区域进行照射。
这里, 为了更清楚地理解本发明的实施例, 在所述封装基板中, 可以 将所述第一玻璃基板 10 远离所述玻璃胶 30 的一面称为第一非封装面 10b; 同理, 在所述器件基板中, 可以将所述第二玻璃基板 20远离所述待 封装器件的一面称为第二非封装面。
考虑到所述激光 40的光束和所述均勾的压合力 50与同一个基板直接 接触时,在使得所述封装基板与所述器件基板贴合紧密的同时能够尽可能 地减少所述玻璃胶 30在受到所述激光 40照射的过程中产生的热应力,因 此, 本发明实施例可以为, 参考图 5或图 6所示, 所述激光 40的光束和 所述均匀的压合力 50均与所述封装基板的所述第一非封装面 10b同时接 触,即:所述激光 40的光束直接照射到所述封装基板的第一非封装面 10b, 并穿透所述第一玻璃基板 10照射到位于封装区域 10a的所述玻璃胶 30, 同时, 所述均勾的压合力 50直接施加在所述第一非封装面 10b上。
所述激光 40的光束和所述均匀的压合力 50也可以均与所述器件基板 的所述第二非封装面同时接触, 在此不再赘述。
本发明实施例提供了一种封装方法,所述封装方法包括: 在第一玻璃 基板 10的封装区域 10a形成玻璃胶 30图案层; 将形成有所述玻璃胶 30 的封装基板和器件基板贴合,使所述封装基板的所述封装区域 10a与所述 器件基板的封装区域 10a对位; 通过对所述封装区域 10a进行激光 40照 射, 对所述玻璃胶 30进行烧结, 并在所述激光 40照射的同时, 对所述封 装区域 10a施加均勾的压合力 50。
通过上述封装方法, 一方面, 在所述激光 40的光束照射到所述封装 区域 10a的同时, 给所述封装区域 10a施加均勾的压合力, 能够尽可能地 使所述封装基板与所述器件基板贴合紧密, 这样有利于所述玻璃胶 30经 所述激光 40的照射熔融后将所述封装基板与所述器件基板密封, 并且, 由于在本发明实施例提供的封装方法中,对所述封装区域 10a的所述玻璃 胶 30进行所述激光 40照射的同时还对所述封装区域 10a施加有均勾的压 合力, 因而与现有技术相比,本发明实施例可简化所述封装方法的工艺过 程。另一方面, 由于所述玻璃胶 30受到所述激光 40照射的同时还受到施 加在所述封装区域 10a的均勾的压合力, 可减少所述玻璃胶 30在受到所 述激光 40照射的过程中由于受热而产生的应力, 从而减少由于所述激光 40的光束照射到所述玻璃胶 30时产生的应力而导致的所述玻璃胶 30经 烧结后形成的封装玻璃开裂或剥离等封装不良现象。
可选的, 对于所述步骤 S01, 可以包括几个子步骤:
S101、 对所述第一玻璃基板 10进行清洗。 5102、 对清洗过的所述第一玻璃基板 10进行干燥处理, 去除所述第 一玻璃基板 10表面的水汽。
5103、 对干燥后的所述第一玻璃基板 10的所述封装区域 10a进行表 面处理, 并釆用例如点胶涂覆或丝网印刷的方法, 在所述第一玻璃基板 10的所述封装区域 10a形成玻璃胶 30图案层。
例如, 对所述第一玻璃基板 10的所述封装区域 10a进行所述表面处 理为釆用等离子体进行表面处理, 以使所述玻璃胶 30能够与所述第一玻 璃基板 10更牢固地结合。
可选的, 所述步骤 S03中的压合力 50可釆用气流压合力、 或磁力压 合力、 或机械压合力等。 考虑到在实现上述封装过程中, 气流压合力操作 灵活简便, 因此,本发明实施例釆用的所述压合力 50例如为气流压合力。 所述气流可包含惰性气体或氮气气体。
基于此, 对于所述步骤 S03, 可以包括如下两种方式:
第一种方式为: 参考图 5所示,在所述封装基板的所述第一非封装面 10b,通过控制所述激光 40的光束沿所述封装区域 10a移动,对所述玻璃 胶 30进行烧结, 并控制所述气流与所述激光 40的光束同步移动。
也可以在所述器件基板的第二非封装面, 通过控制激光 40的光束沿 所述封装区域 10a移动, 对所述玻璃胶 30进行烧结, 并控制所述气流与 所述激光 40的光束同步移动。
考虑到所述器件基板中待封装器件往往是具有规则图案的薄膜器件, 因此, 可选的, 所述封装区域 10a为封闭矩形环; 其中, 由于常规的激光 束的光斑为圓形, 而所述激光 40的能量往往集中在光束的光斑中心处, 因此,为了使所述玻璃胶 30能够均勾地吸收所述激光 40的光束,所述矩 形环的环宽度小于所述激光束的光斑直径。
为了避免所述激光 40的光束照射到所述器件基板中待封装的器件, 使所述待封装的器件受热而影响其性能, 沿所述器件基板的板面垂直方 向, 所述激光 40光束的光斑还应远离所述待封装的器件。
此外, 本发明实施例不限定实现所述气流与所述激光 40的光束同步 的具体方式, 例如可以使发射所述激光 40光束的设备与产生所述气流的 设备连接同一个马达,通过控制设备给该马达输入特定指令,使发射所述 激光 40光束的设备与产生所述气流的设备沿所述封装区域移动, 从而使 激光 40的光束和气流同步沿所封装区域 10a移动。
第二种方式为: 参考图 6所示,在所述封装基板的所述第一非封装面 10b,通过控制所述激光 40的光束沿所述封装区域 10a移动,对所述玻璃 胶 30进行烧结,并在所述激光 40照射的同时,对整张所述封装基板施加 所述气流。
也可以在所述器件基板的第二非封装面, 通过控制激光 40的光束沿 所述封装区域 10a移动, 对所述玻璃胶 30进行烧结, 并在所述激光 40 照射的同时, 对整张所述器件基板施加所述气流。
此处,由于所述气流是与整张所述封装基板或所述器件基板直接接触 的, 应根据所述玻璃胶 30的厚度来严格控制所述气流的大小, 从而避免 在所述激光 40照射所述玻璃胶 30时,由于所述气流的压合力过大使得所 述封装基板与所述器件基板之间的距离过小,导致所述封装基板对所述待 封装器件产生挤压, 从而影响所述待封装器件的性能。
在上述基础上,考虑到封装方法常应用在封装制造有机电致发光二极 管( Organic Light Emitting Diode, 简称 OLED )显示器领域中, 因此, 下 面以待封装器件为 OLED为例进行说明。
由于 OLED显示器包括 OLED发光器件 21,所述 OLED发光器件 21 包括有机功能层、 阴极和阳极, 而有机功能层的材料极易与周围环境中的 水汽、 氧发生反应, 从而导致所述 OLED发光器件 21的性能失效, 因而 需要在制造 OLED显示器的过程中对所述 OLED发光器件 21进行封装, 以使所述 OLED发光器件与周围环境严格地隔离开。
在使用所述封装基板进行封装时, 考虑到所述 OLED发光器件 21往 往具有一定的厚度, 而位于所述封装基板上的所述玻璃胶 30的厚度需要 大于所述 OLED发光器件 21的厚度, 才能在所述封装基板与所述器件基 板之间形成封闭空间用以隔离所述 OLED发光器件 21与外界环境。因此, 所述激光 40的光束需要对所述玻璃胶 30进行较长时间的照射才能够使所 述玻璃胶 30吸收足够的光能进而烧结, 这就有可能使得所述封装基板与 所述器件基板之间发生粘合不良或不均匀; 并且,较长时间的激光照射有 可能使所述激光 40的热量传递至所述 OLED发光器件 21 内, 进而影响 所述 OLED发光器件 21的性能; 此外, 在所述激光 40照射的过程中, 所述玻璃胶 30 受热会将其中的有机物成分会挥发出来, 有可能与所述 OLED发光器件 21发生反应。
因此, 例如, 在上述 S01和 S02之间还包括: 对形成有所述玻璃胶 30的所述封装基板进行预加热, 以使所述玻璃胶 30形成无机玻璃。
这里, 应根据所述玻璃胶 30的材料确定所述预加热的升温曲线, 例 如, 对于常规的 OLED显示器封装用玻璃胶 30, 可以将形成有所述玻璃 胶 30的封装基板放置在加热炉中, 通过与加热炉连接的温控设备, 使所 述玻璃胶 30通过一定的升温曲线逐渐加热, 经冷却后形成无机玻璃。
在此情况下, 在上述步骤 S03中, 可以对所述玻璃胶 30预加热后形 成的无机玻璃进行烧结, 从而使所述无机玻璃能够在后续的所述激光 40 加热过程中形成固化的封装玻璃。
此外, 考虑到所述 OLED发光器件 21需要严格地与大气环境中的水 汽、 氧隔离开, 因此, 例如, 所述步骤 S02和步骤 S03均在无水、 无氧 的环境中进行。
需要说明的是, 本发明实施例不限于封装 OLED发光器件 21, 还可 封装其他薄膜器件,例如,可以釆用本发明实施例提供的所述封装方法封 装太阳能电池、 或薄膜传感器等。
基于上述的描述,由于所述玻璃胶 30需要将吸收的所述激光 40的光 能转化为热能来使所述玻璃胶 30烧结, 因此,所述玻璃胶 30釆用的材料 应对所述激光 40具有较强吸收能力, 因而, 例如, 所述玻璃胶 30包括玻 璃粉、 有机溶剂以及粘合剂。
所述有机溶剂以及粘合剂用来使所述玻璃粉具有一定的粘性,并能够 固定在所述第一玻璃基板 10的表面。
可以根据所述玻璃胶 30中的玻璃粉的光学吸收系数以及所述玻璃胶 30的厚度来确定所述激光 40的波长和功率。
下面提供一个示例, 以详细描述上述的封装方法。 在该示例中, 所述
OLED显示装置包括器件基板和封装基板;所述器件基板包括第二玻璃基 板 20、 以及设置在所述第二玻璃基板 20上的 OLED发光器件 21, 所述 OLED发光器件 21包括有机功能层、 阴极和阳极; 所述封装基板包括第 一玻璃基板 10。
所述封装方法包括如下步骤:
Sl l、 对第一玻璃基板 10 进行清洗, 对清洗过的所述第一玻璃基板 10进行干燥处理, 去除所述第一玻璃基板 10表面的水汽; 对干燥后的所 述第一玻璃基板 10的所述封装区域 10a进行等离子体表面处理, 并釆用 点胶涂覆方法, 在所述第一玻璃基板 10的所述封装区域 10a形成玻璃胶 30的图案层。
S12、 对形成有所述玻璃胶 30 图案的所述封装基板进行加热, 使所 述玻璃胶 30形成无机玻璃。 升温曲线如下所述:
第一升温阶段: 将形成有所述玻璃胶 30的所述封装基板放置于加热 炉内, 使所述封装基板从室温均匀加热至 150~200°C, 并在此温度范围内 保温 30min。
第二升温阶段:在加热炉内使所述封装基板从上述 150~200°C温度范 围内均勾加热至 300~350°C, 并在此温度范围内保温 20min, 以除去所述 玻璃胶 30内的有机溶剂和粘合剂中的有机成分。
第三升温阶段:在加热炉内使所述封装基板从上述 300~350°C度范围 内均匀加热至 400~500°C, 并在此温度范围内保温 60min, 从而使所述玻 璃胶 30熔融, 经緩慢冷却至室温后形成硬化的无机玻璃。
S 13、 将形成有所述无机玻璃的所述封装基板和所述器件基板贴合, 使所述封装基板的所述封装区域 10a与所述器件基板的封装区域 10a对 位。
S14、 参考图 6所示, 控制红外激光 40从所述封装基板的第一非封 装面 10b直接照射到所述封装区域 10a, 使所述红外激光 40的光束穿透 所述封装基板的第一玻璃基板 10,对形成在所述封装基板的封装区域 10a 的所述无机玻璃进行烧结, 并控制所述红外激光 40沿所述封装区域 10a 移动,与此同时给所述封装基板的第一非封装面 10b施加均匀的气流压合 力。
此处, 由于所述气流是与整张所述封装基板直接接触的,应根据所述 玻璃胶 30预加热后形成的所述无机玻璃的厚度来严格控制所述气流的大 小,从而避免在所述红外激光照射所述无机玻璃时, 由于所述气流的压合 力过大使得所述封装基板与所述器件基板之间的距离过小,使所述封装基 板对所述 OLED发光器件 21产生挤压, 影响所述 OLED发光器件 21的 性能。
通过上述步骤 S11 S14便可在所述封装基板与所述器件基板之间形 成固化的封装玻璃, 由于玻璃具有良好的隔离作用,从而可以将所述器件 基板中待封装的 OLED发光器件 21密闭起来。
在上述基础上,本发明实施例还提供了一种显示装置, 包括封装基板 和器件基板,所述封装基板和所述器件基板按照上述的所述封装方法进行 封装。
所述显示装置还包括釆用上述封装方法形成在所述封装基板和所述 器件基板之间的固化的封装玻璃。
所述显示装置可以是有机电致发光二极管显示装置、有机电致发光二 极管显示面板、 电子纸、 等离子显示装置、 显示器、 数码相框、 手机、 平 板电脑等具有任何显示功能的产品或部件。考虑到 OLED显示装置中的发 光器件需要严格地与周围环境中的水、氧隔离开来, 以使发光器件的密闭 性达到水汽渗透率小于 l(T6g/m2/天, 氧气渗透率小于 l(T3cm3/ m2/天的使 用要求, 因此, 根据本发明的一个示例, 所述显示装置为 OLED显示装 置, 所述器件基板包括设置在所述第二玻璃基板上的 OLED发光器件; 其中, 所述 OLED发光器件包括有机功能层、 阴极和阳极。 一方面,可以减小所述 OLED显示装置的封装工艺过程,提高所述 OLED 显示装置的封装效率; 另一方面, 由于釆用上述封装方法可以避免所述封 剥离等封装不良现象, 可以减小由于封装不良而引起的所述 OLED发光 器件性能失效,从而降低所述 OLED显示装置的不良率,延长所述 OLED 显示装置的使用寿命。
需要说明的是,本发明所有附图是所述封装方法中涉及封装基板以及 器件基板的简略的示意图, 以清楚地描述本发明的技术方案,对于其他未 显示的结构可以为常规结构。
通过上述封装方法,一方面,在所述激光的光束照射到所述封装区域 的同时,给所述封装区域施加均勾的压合力, 能够尽可能地使所述封装基 板与所述器件基板贴合紧密,这样有利于所述玻璃胶经所述激光的照射熔 融后将所述封装基板与所述器件基板密封, 并且, 与常规技术相比, 本发 明的实施例可简化所述封装方法的工艺过程; 另一方面, 由于所述玻璃胶 受到所述激光照射的同时还受到施加在所述封装区域的均匀的压合力,可 减少所述玻璃胶在受到激光照射的过程中由于受热而产生的应力,从而减 少由于所述激光的光束照射到所述玻璃胶时产生的应力而导致的所述玻 璃胶经烧结后形成的封装玻璃开裂或剥离等封装不良现象。
当所述封装方法应用于显示装置时,可以减少所述显示装置的封装工 艺步骤, 提高所述显示装置的封装效率。 同时, 由于釆用上述封装方法可 装玻璃开裂或剥离等封装不良现象,也可以减小由于封装不良而引起的所 述显示装置性能失效,从而降低了所述显示装置的不良率,延长了所述显 示装置的使用寿命。
以上所述, 仅为本发明的示例性实施方式, 但本发明的保护范围并不 可轻易想到许多变化或替换, 这些变化或替换都应涵盖在本发明的保护范 围之内。 因此, 本发明的保护范围以随附权利要求的保护范围为准。
