本发明的实施方式
下面详细描述本申请的实施方式,所述实施方式的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施方式是示例性的,仅用于解释本申请,而不能理解为对本申请的限制。
请参阅图1,图1为本申请实施例所提供的OLED显示面板的第一种实施方式的截面示意图。
本申请实施例提供一种OLED显示面板100,包括:
发光基板10;
封装薄膜20,封装薄膜20包括设置在发光基板10上的第一无机层201,第一无机层201上设置有有机层202,且有机层202上设置有覆盖第一无机层201和有机层202的第二无机层203;其中,
第一无机层201朝向有机层202的表面上设置有第一凹凸结构30。
例如,该发光基板10可以是形成有聚酰亚胺(Polyimide,PI)、薄膜晶体管(Thin Film Transistor,TFT)器件以及有机发光层的玻璃基板。在发光基板10到有机层202的方向上,层叠设置有第一无机层201、有机层202以及第二无机层203。其中,该第一无机层201的材料与第二无机层203的材料均为氧化铝、氧化铁以及氧化锆中的任一种。
另外,该第一凹凸结构30与第一无机层201可以一体成型。比如,在发光基板10形成第一无机层201后,可以利用低温等离子或激光的工艺对第一无机层201进行处理,以形成第一突起结构30。即,在一些实施例中,第一无机层201与第一凹凸结构30一体成型。这样在提高封装可靠性的同时,还可以减小工艺生产的时间,提高了生产效率。
紧接着,请参阅图2、图3以及图4,图2为本申请实施例所提供的OLED显示面板的第二种实施方式的截面示意图,图3为本申请实施例所提供的OLED显示面板的第三种实施方式的截面示意图,图4为本申请实施例所提供的OLED显示面板的第四种实施方式的截面示意图。
在本申请实施例中,还包括挡墙50,挡墙50设置在发光基板10的边缘区域上;其中,第一无机层201上的第一凹凸30结构靠近挡墙50设置。
该挡墙50的材料可以有机物,也可以无机物,具体根据实际情况进行设定。形成挡墙的方法有很多种,在此不一一赘述。另外,该第一凹凸结构30的截面形状如图2、图3以及图4所示,当然还可以别的截面形状。在此,仅仅以这三种形状为例进行说明。
将挡墙50设置在发光基板10的边缘区域上,当需要在第一无机层201上形成有机层202时,能够使得有机层202在指定的区域上形成。并且,第一凹凸结构30增大了有机层202溢流的路径,因此挡墙50与第一凹凸结构30配合,可以避免有机层202在流平过程中出现扩散的问题,使得有机层202不会与空气接触,造成封装失效,从而提高了封装的可靠性。
请参阅图5、图6以及图7,图5为本申请实施例所提供的OLED显示面板的第五种实施方式的截面示意图,图6为本申请实施例所提供的OLED显示面板的第六种实施方式的截面示意图,图7为本申请实施例所提供的OLED显示面板的第七种实施方式的截面示意图。
第一凹凸结构30包括一主体部301以及多个突起部302;其中,
主体部301设置在第一无机层201上,多个突起部302与主体部301连接且间隔设置在主体部301上。
在本实施例中,主体部301设置在第一无机层201上,即第一凹凸结构30与第一无机层201不同层设置。比如,在发光基板10上形成第一无机层201后,再在第一无机层201上形成一层无机层。然后,通过蚀刻的工艺在第一无机层201上形成第一凹凸结构30,如图3所示。通过该方法,在形成第一凹凸结构30时,不会由于蚀刻而造成第一无机层201的损伤,从而导致封装可靠性下降。另外,突起部302的形状有很多种,在本实施例中,仅仅以突起部302的截面为三角形进行说明,当然突起部302的截面也可以为矩形或者圆形,也即,突起部302的截面为矩形、圆形或三角形,如图5、图6以及图7所示。
在一些实施例中,多个突起部302的形状、大小均一致。也即,每个突起部302的尺寸一致。将每个突起部302的尺寸设置成同一尺寸,不仅便于生产,提升了生产效率。并且,能够保证有机层202在第一凹凸结构30上分布均匀,避免在封装过程中,有机层202由于在第一凹凸结构30上分布不均匀,而出现溢流的问题,进一步提高了封装的可靠性。
请继续参阅图8、图9以及图10,图8为本申请实施例所提供的OLED显示面板的第八种实施方式的截面示意图,图9为本申请实施例所提供的OLED显示面板的第九种实施方式的截面示意图,图10为本申请实施例所提供的OLED显示面板的第十种实施方式的截面示意图。
在一些实施例中,还包括平坦层60,平坦层60设置在发光基板10上,第一无机层201覆盖平坦层60;
其中,平坦层60朝向第一无机层201的表面上设置有第二凹凸结构32,第一无机层201朝向平坦层60的表面上设置有第三凹凸结构33。
在第一无机层201朝向有机层的表面上设置第一凹凸结构30,并且在第一无机层201朝向平坦层60的表面上设置第三凹凸结构33。一方面,可以增加有机层20溢流方向的路径,阻挡有机层20向外溢出,提高了封装的可靠性;另一方面,通过设置第三凹凸结构33,可以增大第一无机层201与平坦层60的接触面积,从而有效的提高膜层的紧密性。
在一些实施例中,第一凹凸结构30、第二凹凸结构32以及第三凹凸结构33一一对应。
在一些实施例中,第一凹凸结构30在发光基板10上投影与第二凹凸结构32在发光基板10上的投影重合。
相应的,本申请还提供一种显示装置,包括本申请任一实施例提供的OLED显示面板。
