为让本发明的上述内容能更明显易懂,下文特举优选实施例,并配合所附图式,作详细说明如下:
图1为现有的显示面板的结构示意图。
图2为本发明实施例提供的显示面板的第一结构示意图。
图3为本发明实施例提供的显示面板的第二结构示意图。
以下各实施例的说明是参考附加的图式,用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语,例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等,仅是参考附加图式的方向。因此,使用的方向用语是用以说明及理解本发明,而非用以限制本发明。
在图中,结构相似的单元是以相同标号表示。
在本文中提及“实施例”意味着,结合实施例描述的特定特征、结构或特性可以包含在本发明的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例,也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是,本文所描述的实施例可以与其它实施例相结合。
本发明实施例提供了一种显示装置,该显示装置包括显示面板。请参照图2,图2为本发明实施例提供的显示面板的第一结构示意图。显示面板1包括基板11、有机发光器件12、多个阻隔柱13、吸水层14以及薄膜封装层15。
基板11用于承载设置在其上的有机发光器件12。在一实施例中,基板11可以为采用聚酰亚胺、聚碳酸酯、聚醚砜、聚对苯二甲酸乙二醇酯、聚萘二甲酸乙二醇酯、多芳基化合物等柔性材料组成的柔性基板。基板11上还可以设置薄膜晶体管层。
有机发光器件12可以包括两层电极以及夹在两层电极之间的有机发光层。其中,有机发光器件12可以为下发光型器件,也可以为上发光型器件。
如图2或3所示,多个阻隔柱13设置在基板11上,并且环绕有机发光器件12设置。阻隔柱13位于显示面板1的非显示区域,其可以阻隔薄膜封装层15外溢。
在一实施例中,为了防止显示面板1边缘区域的薄膜封装层15坡度过大,可以设置分布在有机发光器件12周围的两圈阻隔柱13。需要说明的是,阻隔柱13的圈数可以显示面板1边缘区域的薄膜封装层15形状进行设置,在此不做具体限定。
当显示面板1中设有不止一圈阻隔柱13时,可以依次减少靠近显示面板1边缘区域的阻隔柱13的高度,即离显示面板1边缘区域越近的阻隔柱13,其高度越小。这样可以使显示面板1边缘区域的薄膜封装层15的坡度平滑减小,降低其断裂的可能性。
在一实施例中,阻隔柱13包括本体和设置本体上的吸水膜层。其中,本体可以采用光阻材料制成,吸水膜层可以采用具有吸水性能的材料制成,比如树脂、丙烯酸酯等有机吸水材料,和/或碳酸钙等无机吸水材料。
吸水层14设置在基板11上,该吸水层14在薄膜封装层15发生断裂时,可以有效吸收外界侵入的水汽。
在一实施例中,不论阻隔柱13为一圈还是多圈,吸水层14都可以设置在全部阻隔柱13的外围,即环绕全部阻隔柱13设置。此时,可以设置吸水层14的高度小于阻隔柱13的高度,以使显示面板1边缘区域的薄膜封装层15的坡度平滑减小,降低其断裂的可能性。
在一实施例中,可以将吸水层14的高度范围设置为0.1微米至0.3微米之间。这样,吸水层14还可以起辅助支撑薄膜封装层15的作用。
在一实施例中,如果设置了两圈间隔设置的阻隔柱13,也可以将吸水层14设置在两个阻隔柱13之间的位置。
在一实施例中,吸水层14的组成材料可以包括无机吸水材料,也可以包括有机吸水材料。即吸水层14可以采用无机吸水材料制作,也可以是无机吸水材料制作,还可以采用二者共同制作。在一实施例中,无机吸水材料可以包括碳酸钙,有机吸水材料可以包括树脂和/或丙烯酸酯。
其中,吸水层14可以与阻隔柱13间隔设置。具体的,可以使用丙烯酸酯,通过喷墨打印方式,形成上述吸水层14。也可以使用环氧树脂、亚克力树脂和固化剂,形成上述吸水层14。
薄膜封装层15可以包括多层薄膜结构。如图2所示,薄膜封装层15包括第一薄膜封装层151、第二薄膜封装层152和第三薄膜封装层153。其中,第一薄膜封装层151、第三薄膜封装层153可以为无机薄膜层,第二薄膜封装层152可以为有机薄膜层。具体的,可以先在基板11、有机发光器件12以及阻隔柱13上进行CVD(chemical vapor
deposition,化学气相沉积)操作,形成第一薄膜封装层151。然后在第一薄膜封装层151上进行喷墨打印操作,形成第二薄膜封装层152。其中,第二薄膜封装层152位于阻隔柱13靠近有机发光器件12的一侧。最后在第二薄膜封装层152、第一薄膜封装层151以及吸水层14上进行CVD操作,形成第三薄膜封装层153。
本发明的显示面板及显示装置,通过设置吸水层,可以在薄膜封装层断裂时,吸收外界水汽,提高显示面板的良率。
综上所述,虽然本发明已以优选实施例揭露如上,但上述优选实施例并非用以限制本发明,本领域的普通技术人员,在不脱离本发明的精神和范围内,均可作各种更动与润饰,因此本发明的保护范围以权利要求界定的范围为准。
