所述第二封装层1042内还设置有至少一纤维网,所述纤维网具有至少两网孔,所述网孔的直径小于所述聚苯乙烯-聚氮-异丙基丙烯酰胺纳米粒子和/或聚甲基丙烯酸甲酯纳米粒子的直径,所述纤维网用于使得所述第二封装层1042中的所述聚苯乙烯-聚氮-异丙基丙烯酰胺纳米粒子和/或聚甲基丙烯酸甲酯纳米粒子有序排列,从而提高所述聚苯乙烯-聚氮-异丙基丙烯酰胺纳米粒子和/或聚甲基丙烯酸甲酯纳米粒子在所述第二封装层1042中分布的均匀度。所述纤维网还用于使得所述第二封装层1042中的所述聚苯乙烯-聚氮-异丙基丙烯酰胺纳米粒子和/或聚甲基丙烯酸甲酯纳米粒子分层排列,以提高所述第二封装层1042对水氧的阻隔效果。
所述纤维网所对应的平面与所述第二封装层1042所对应的平面(或所述第一封装层1041所对应的平面)平行或大致平行。
所述纤维网设置有延伸部,所述延伸部自所述纤维网的纤维网主体往所述纤维网主体的外部延伸,所述延伸部与所述纤维网主体所对应的具有预定夹角,所述预定夹角处于30度至90度的范围内,例如,所述预定夹角为30度、35度、40度、45度、50度、55度、60度、65度、70度、75度、80度、85度、90度。所述延伸部用于支撑所述纤维网主体,以使所述纤维网主体与所述第二封装层1042所对应的平面(或所述第一封装层1041所对应的平面)平行或大致平行。
所述网孔设置于所述纤维网主体中。
在本发明中,由于所述封装构件104的所述第一封装层1041和所述第三封装层1043的材料均为无机材料,夹设于所述第一封装层1041和所述第三封装层1043之间的所述第二封装层1042的材料为有机材料10421,所述第二封装层1042中设置有有机纳米粒子10422,因此,本发明能提高对显示面板外部的水氧的阻隔效果,以有效防止显示面板外的水氧进入到显示面板内。
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。
