为使本领域的技术人员更好地理解本发明的技术方案, 下面结 合附图和具体实施方式对本发明的显示面板、显示面板的制备方法及 显示装置作进一步详细描述。应当注意的是, 附图中示出的各层结构 的厚度、 大小等均为示例性的, 其目的仅在于对本发明进行说明, 而 不反映实际应用中的尺寸, 更不是对本发明的限制。 实施例 1 : 本实施例提供一种显示面板, 该显示面板划分为显示区和非显 示区, 且该显示面板包括对合在一起的上基板和下基板, 下基板上的 显示区中设置有控制结构和显示结构,上基板上的显示区中设置有感 应结构, 感应结构与显示结构相对应地设置, 感应结构中设置有稳定 子结构。
图 1示出了该实施例的显示面板的剖视图。
如图 1 所示, 显示面板的下基板包括依次层叠设置的第一衬底 1、 控制结构 3和显示结构 4。 显示面板的上基板包括依次层叠设置 的第二衬底 2和第一感应结构 51。 。 此外, 显示面板还包括封框材 料 7, 其设置在显示结构 4的周边, 以将控制结构 3与第一感应结构
51进行粘接, 且将显示结构 4密封在控制结构 3、 第一感应结构 51 以及封框材料 7之间, 从而使得下基板与上基板相互粘接。 结果, 如 图 1所示, 形成了从下往上依次为第一衬底 1、 控制结构 3、 显示结 构 4和封框材料 7、 第一感应结构 51、 第二衬底 2的层叠结构。
此外, 在一些示例中, 上基板中第二衬底 2 的远离显示结构 4 的一侧还设置有用来提高对比度的上偏光片 61, 该上偏光片 61优选 为圆偏光片。
优选地, 控制结构 3为薄膜晶体管层, 显示结构 4为有机电致 发光层。 更优选地, 有机电致发光层至少包括阳极层、 发光层和阴极 层。
第一感应结构 51是本发明的感应结构的一个示例。如图 2所示, 第一感应结构 51包括按远离第二衬底 2的方向依次设置的感应膜层 511和稳定子结构 512。 也就是说, 在本发明的显示面板中, 针对感 应膜层设置了一层稳定子结构, 从而有助于感应膜层的稳固性。优选 地, 稳定子结构与感应膜层可以具有实质相同的大小, 即稳定子结构 可以基本覆盖感应膜层的整个表面。优选地, 稳定子结构可以形成为 将感应膜层夹在该稳定子结构与第二衬底之间的保护层,从而使得感 应膜层不容易受到损伤。稳定子结构 512可以由能够保护感应膜层的 任何适当的材料形成。优选地, 稳定子结构 512可以由防电磁干扰的 材料形成, 例如由有机材料形成。 采用有机材料形成的稳定子结构 512一方面能够使显示面板免受内部或外部的电磁干扰, 从而确保显 示面板的性能稳定; 另一方面, 该稳定子结构 512坚固耐用, 能很好 地保护感应膜层 511, 使感应膜层 511不容易被磕碰损坏。 优选地, 感应膜层 511可以采用碳纳米管或氧化铟锡材料形成。
优选地, 第一衬底 1与第二衬底 2可以采用透明玻璃材料形成。 更优选地,可以通过化学减薄工艺对第一衬底 1和第二衬底 2进行减 薄处理,例如使得第一衬底 1与第二衬底 2的厚度范围为 0. 1-0. 3 mmo 通过这种方式,由于稳定子结构 512的添加而增大的整体厚度得到了 减小, 使得显示面板更加轻薄, 既美观又便于携带。
在一些示例中, 显示面板还包括外围电路 (图 1 中未示出) 。 优选地, 将上基板与下基板错位设置, 并将外围电路设置于通过错位 而裸露出的非显示区内。如此设置, 使得外围电路的设置更加灵活方 便, 且可进一步縮小显示面板的非显示区, 有利于显示面板向轻便小 型化方向发展。
优选地, 显示面板的上基板和下基板的显示区的尺寸相同, 非 显示区的尺寸也相同, 并且非显示区仅设置在显示区的一侧。在上基 板和下基板的对合中,上基板和下基板的显示区在正投影方向上相对 应地设置,从而上基板的非显示区和下基板的非显示区设置在相对的 两侧。这种方式既使得显示区能互相对应, 又使上基板中的非显示区 和下基板中的非显示区由于错位而均得以裸露出来,从而使得外围电 路在非显示区的设置更加方便。
本实施例还提供一种上述显示面板的制备方法。 该制备方法包 括: 分别形成上基板和下基板的步骤; 以及将上基板与下基板对合在 一起以形成显示面板的步骤, 其中, 下基板上的显示区中形成有控制 结构和显示结构, 上基板上的显示区中形成有感应结构, 感应结构与 显示结构相对应地设置, 感应结构中形成有稳定子结构。
本实施例的显示面板的具体制备过程如图 3A至图 3H所示。 首先, 制备下基板。 形成下基板的步骤具体包括以下步骤 S10-Sl l o
步骤 S10 : 准备第一衬底 1 (如图 3A所示) 。 步骤 S l l : 在第一衬底 1 上形成包括控制结构 3 的图形 (如图 3B所示) 。 优选地, 控制结构 3为薄膜晶体管层。
步骤 S 1 1之后还进一步包括在控制结构 3的上方形成显示结构 4 的步骤 (如图 3C所示) 。 优选地, 显示结构 4为有机电致发光层。 可以采用蒸镀方式在真空蒸镀环境中形成显示结构 4。
至此, 下基板制备完毕。
随后, 制备上基板。 形成上基板的步骤具体包括以下步骤 S20- S21。
步骤 S20 : 准备第二衬底 2 (如图 3D所示) 。
步骤 S21 : 在第二衬底 2的一侧形成包括感应结构(即第一感应 结构 51 ) 的图形 (如图 3E所示) 。 感应结构形成于上基板与下基板 对合时第二衬底 2的靠近显示结构 4的一侧。其中, 感应结构包括按 远离第二衬底 2的方向依次设置的感应膜层和稳定子结构。 优选地, 稳定子结构为采用有机材料形成的保护层。其中, 形成感应结构的步 骤具体可以包括以下步骤 S50-S51。
步骤 S50 : 形成包括感应膜层的图形。可以采用碳纳米管通过拉 制工艺来形成感应膜层的图形。作为替代,也可以采用氧化铟锡材料, 通过构图工艺形成包括所述感应膜层的图形。
步骤 S51 : 在感应膜层上形成作为保护层的稳定子结构。 可以采 用有机材料通过涂布工艺来形成稳定子结构。该稳定子结构既能使显 示面板免受内部或外部的电磁干扰,又能很好地保护感应膜层免遭磕 碰损坏
至此, 上基板也制备完毕。
应当注意的是, 稳定子结构的设置会使得显示面板的厚度加大。 因此, 在后续的上基板和下基板对合步骤完成后, 可以执行对第一衬 底和第二衬底进行减薄的步骤, 以减小显示面板的整体厚度。
需要说明的是, 对上基板和下基板的制备顺序不做限定, 可以 先制备下基板再制备上基板, 也可以先制备上基板再制备下基板, 或 者上基板和下基板同时制备,在实际生产过程中可根据设备条件或工 艺情况进行灵活安排。 另外, 在上基板和下基板对合时, 可以是上基 板与下基板均已经全部制备完毕, 也可以是上基板和 /或下基板的部 分制备完毕(这种情况主要是针对后面的感应结构的设置位置不同于 本实施例的感应结构的设置位置的实施例而言) 。
然后, 将上基板和下基板对合以形成显示面板。 该对合步骤具 体包括以下步骤 S3-S31。
步骤 S30 : 在下基板的非显示区的边缘区域涂布封框材料 7。 其中, 封框材料 7 可以为低熔点玻璃粉浆料, 其熔化温度的范 围为 60 °C -80 °C。 当然, 也可以在上基板的非显示区的边缘区域涂布 封框材料 7。
步骤 S31 : 在步骤 S30之后, 将上基板与下基板对合 (如图 3F 所示) 。 通过封框材料 7, 将上基板和下基板粘结在一起。
在上基板和下基板对合之后,还可以进行对下基板中第一衬底 1 的远离显示结构 4 的一侧和上基板中第二衬底 2 的远离显示结构 4 的一侧进行减薄的步骤 (如图 3G所示为减薄后的剖视图) , 减薄的 步骤具体包括以下步骤 S40-S42。
步骤 S40 : 在上基板和下基板之间的非显示区涂布保护材料。 其中, 保护材料可以为热固化材料或光固化材料, 该材料能够 防止在化学减薄过程中化学溶液对显示结构、控制结构及感应结构等 显示面板的内部结构及因上基板和下基板错位设置而裸露的非显示 区的腐蚀损坏。
步骤 S41 :对下基板中第一衬底 1的远离显示结构 4的一侧和上 基板中第二衬底 2的远离显示结构 4的一侧进行减薄。
其中, 可以采用化学减薄工艺来进行上述减薄。 化学减薄主要 有两种方式:一种方式为将对合的上下基板浸泡在混酸溶液中, 混酸 溶液对第一衬底 1和第二衬底 2进行化学腐蚀减薄,通过控制浸泡的 时间和温度, 使第一衬底 1和第二衬底 2分别被减薄到 0. 1-0. 3 mm 的厚度范围内; 另一种方式为对对合的上下基板进行混酸溶液喷淋, 通过控制喷淋的压力、 喷淋时间、 温度及喷淋量, 使第一衬底 1和第 二衬底 2分别被减薄到 0. 1-0. 3 mm的厚度范围内。
在本实施例中, 采用化学减薄工艺对第一衬底和第二衬底进行 减薄。 由于化学减薄工艺比较成熟且成本较低, 因此很容易控制第一 衬底和第二衬底的减薄厚度,同时能够低成本地实现显示面板的薄型 化。
步骤 S42 : 去除所述保护材料。
在上述减薄步骤完成之后, 继续进行如下步骤 S32-S33 , 以完成 对合。
步骤 S32 : 在上基板的外侧贴附偏光片 (即上偏光片 61 ) (如 图 3H所示) 。
步骤 S33 : 在完成步骤 S32的上基板和下基板上贴附外围电路。 基于本实施例的显示面板的结构, 外围电路贴附于上基板和下 基板上的因错位而裸露出的非显示区内。
至此, 显示面板制备完毕。 实施例 2 :

需要说明的是, 该感应结构的形成是在上基板和下基板对合后 进行的, 而上基板和下基板对合是在下基板制备完毕之前进行的。具 体地,在下基板中已经形成控制结构 3和显示结构 4但还未形成感应 结构时, 上基板与尚未制备完毕的下基板对合, 然后经过化学减薄工 艺减薄第一衬底和第二衬底。在这种状态下, 在第一衬底 1的远离控 制结构 3的一侧形成感应结构。
