实施例四
本实施例与上述实施例中的任一项显示面板100相同或相似,不同之处进一步描述了显示面板100的结构。
请参阅图4至图8,图4为本申请一实施例提供的一种显示面板的聚光层的夹角和遮光层的夹角示意图;图5为本申请一实施例提供的一种显示面板的聚光层和遮光层在基底上的正投影的第一种示意图;图6为本申请一实施例提供的一种显示面板的聚光层和遮光层在基底上的正投影的第二种示意图;图7为本申请一实施例提供的一种显示面板的聚光层和遮光层在基底上的正投影的第三种示意图;图8为本申请一实施例提供的一种显示面板的聚光层和遮光层在基底上的正投影的第四种示意图。
在一些实施例中,聚光层17在第二开口171部位的侧壁与聚光层17的底面之间的夹角大于或等于45度。
具体地,如图4所示,聚光层17在第二开口171部位的侧壁与聚光层17的底面之间的夹角为第一倾角α,第一倾角α的角度大于或等于45度。具体地,如图4所示,聚光层17的部分部位和遮光层16设置于一显示面板100的第一膜层21上,第一膜层21可以为封装层14或触控层15等,第一膜层21的结构后续进一步描述,第一膜层21的具体结构名称和作用不限定,只需要第一膜层21能够承载聚光层17的部分部位和遮光层16即可。
具体地,聚光层17的底面为聚光层17与第一膜层21接触的表面,或聚光层17的底面为聚光层17靠近基底11的表面。
具体地,如图4所示,聚光层17在第一膜层21表面上的倾角大于或等于45度,即第一倾角α的角度大于或等于45度。
具体地,当第一倾角α的角度大于或等于45度时,发光器件131发出显示光线经过聚光层17发生反射或折射时,反射或折射的光线更加趋向于正视的光线,可以起到更好聚光效果,从而可以更好的提升显示面板100的正视亮度,可以减小显示面板100的功耗。
在一些实施例中,遮光层16在第一开口161部位的侧壁与遮光层16的底面之间的夹角,小于或等于聚光层17在第二开口171部位的侧壁与聚光层17的底面之间的夹角。
具体地,遮光层16的底面为遮光层16与第一膜层21接触的表面,或遮光层16的底面为遮光层16靠近基底11的表面。
具体地,如图4所示,遮光层16在第一开口161部位的侧壁与遮光层16的底面之间的夹角为第二倾角β,即遮光层16在第一膜层21表面上的倾角为第二倾角β,第二倾角β的角度小于第一倾角α的角度。
具体地,如图3所示,第二倾角β的角度小于第一倾角α的角度,可以避免第一折射显示光线32被遮光层16阻挡或吸收,从而减小光线损失,从而可以更好的提升显示面板100的正视角的亮度,可以减小显示面板100的功耗。
进一步地,优选地,第一倾角α的角度大于或等于45度,第二倾角β的角度小于或等于45度,可以很好地减小光线损失。
在一些实施例中,第一开口161在基底11上的正投影的边缘至第二开口在基底11上的正投影的对应边缘之间的距离大于或等于2微米。
具体地,如图5和图6所示,第一开口161在基底11上的正投影的边缘至第二开口在基底11上的正投影的对应边缘之间的距离为第一距离d1,第一距离d1大于或等于2微米。
具体地,在聚光层17的制作过程中,可能存在对位或图案化等的制程偏差,第一距离d1大于或等于2微米,可以使得显示面板100上遮光层16在第一开口161的全部的部位均被聚光层17覆盖,避免遮光层16在第一开口161部位露出。
在一些实施例中,第一开口161的形状与第二开口171的形状相同。
具体地,第一开口161的形状与第二开口171的形状相同,使得聚光层17在各个部位的光汇聚效应相同或相近,避免出现色偏。
具体地,如图5所示,举例示意了第一开口161的形状与第二开口171的形状均为圆形;如图6所示,举例示意了第一开口161的形状与第二开口171的形状均为矩形。
需要说明的是,当在一些显示面板100中,用户对色偏的要求降低等情况时,第一开口161的形状与第二开口171的形状也可以不同,例如,图7举例示意了第一开口161的形状为矩形,第二开口171的形状为圆形;图8举例示意了第一开口161的形状为椭圆形,第二开口171的形状为矩形。
进一步地,在一些实施例中,聚光层17为透明材料。
具体地,聚光层17为透明材料,可以对发光器件131发出的显示光线进行折射,在反射显示光线的基础上增加折射效用,可以更好的起到光的汇聚效果。
在一些实施例中,聚光层17的可见光的透过率大于或等于90%。
具体地,聚光层17的可见光的透过率大于或等于90%,可以减小聚光层对发光器件131发出的显示光线的吸收,提升显示面板100的亮度,减小功耗。
进一步地,在一些实施例中,聚光层17的材料包括聚甲基丙烯酸甲酯、聚酰亚胺聚、对苯二甲酸乙二醇酯中至少一种。

在一些实施例中,聚光层17在第二开口171部位的侧壁的表面粗糙度小于遮光层16在第一开口161部位的侧壁的表面粗糙度。
具体地,聚光层17在第二开口171部位的侧壁的表面粗糙度较小,或者聚光层17在第二开口171部位的侧壁的表面为光滑表面,可以避免显示光线在聚光层17在第二开口171部位的侧壁表面上发生漫反射,减小显示光线的光损失,避免发生色偏的问题。
在一些实施例中,聚光层17与色阻层18之间的粘结力大于色阻层18与遮光层16之间的粘结力。
具体地,例如在图1所示实施例中,聚光件1711与色阻层18之间的粘结力大于色阻层18与遮光层16之间的粘结力。
具体地,聚光层17与色阻层18之间的粘结力大于色阻层18与遮光层16之间的粘结力,使得遮光层16、聚光层17和色阻层18之间的粘结强度更大,避免膜层分离,避免聚光层17或聚光件1711由于与遮光层16或色阻层18接触面积较小而发生膜层分离。
进一步地,聚光层17的折射率与遮光层16的折射率的差异较小,或聚光层17的折射率与遮光层16的折射率的差异小于或等于0.5,避免显示光线在聚光层17与遮光层16接触的界面发生反射、折射等光学现象,避免显示光线损失。
进一步地,色阻层18的折射率大于聚光层17的折射率,或色阻层18的折射率较聚光层17的折射率大0.1,可以起到较好的光汇聚作用。
在一些实施例中,色阻层18的折射率较聚光层17的折射率大,色阻层18的折射率与聚光层17的折射率差异大于或等于0.2,且色阻层18的折射率与聚光层17的折射率差异小于或等于0.5。
具体地,色阻层18的折射率较聚光层17的折射率大,色阻层18的折射率与聚光层17的折射率差异大于或等于0.2,可以起到较好的光汇聚效果。
具体地,色阻层18的折射率较聚光层17的折射率大,色阻层18的折射率与聚光层17的折射率差异小于或等于0.5,避免色阻层18的折射率较聚光层17的折射率大太多使得光汇聚效果太强,避免侧视角或斜视角亮度衰减过大。
在一些实施例中,遮光层16的光密度大于或等于1.5。
