具体实施方式
相关技术中的显示装置中,需要将制作好的偏光片直接粘贴到显示装置的表面,每块偏光片只有一个方向的吸收轴,使显示装置难以实现立体显示,并且使得显示装置的集成度较低。
基于此,本公开实施提供了一种立体显示装置及其制造方法。下面结合附图和实施例对本公开作进一步的详细说明。可以理解的是,此处所描述的具体实施例仅仅用于解释相关公开,而非对该公开的限定。另外还需要说明的是,为了便于描述,附图中仅示出了与公开相关的部分。
需要说明的是,在不冲突的情况下,本公开中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本公开。
本公开实施例提供了一种立体显示装置,请参考图1和2,本公开的立体显示装置包括交替设置的第一显示区81和第二显示区82,还包括:
衬底基板1,例如衬底基板可以采用柔性材料制作;
多个显示器件10,位于第一显示区81和第二显示区82的衬底基板1之上;
第一偏振膜71,形成于第一显示区81的显示器件10背离衬底基板1的一侧;
第二偏振膜72,形成于第二显示区82的显示器件10背离衬底基板1的一侧;
第一偏振膜71的吸收轴方向与第二偏振膜72的吸收轴方向相互垂直。
在本公开的实施例中,第一显示区显示图像的光的偏振方向与第二显示区显示图像的光的偏振方向相互垂直,配合立体眼镜使得第一显示区的显示图像和第二显示区的显示图像会分别进入人的不同的眼睛,从而实现 立体显示。通过在显示器件背离衬底基板的一侧,形成位于第一显示区的第一偏振膜以及位于第二显示区的第二偏振膜,相比于将制作好的偏光片直接粘贴到显示器件的表面,本公开实施例可以更容易的在显示器件的出光侧形成吸收轴方向不同的偏振膜,并且可以减小立体显示装置的厚度,使得立体显示装置更加轻薄且集成度较高。
具体地,第一显示区的显示图像是通过显示器件发射的光经过第一偏振膜的形成,第二显示区的显示图像是通过显示器件发射的光经过第二偏振膜的形成。第一显示区中的显示器件发射出第一发射光,第一发射光中偏振方向与第一偏振膜的吸收轴平行的光被吸收,第一发射光中偏振方向与第一偏振膜的吸收轴垂直的光能够通过第一偏振膜,同样的,第二显示区发射出第二发射光,第二发射光中偏振方向与第二偏振膜的吸收轴平行的光被吸收,第二发射光中偏振方向与第二偏振膜的吸收轴垂直的光能够通过第二偏振膜。
在具体实施时,本公开实施例提供的立体显示装置需要配合立体眼镜,以实现立体显示,具体地,立体眼镜包括第一偏光镜片和第二偏光镜片,第一偏光镜片和第二偏光镜片可以采用偏光片制作,第一偏光镜片的吸收轴方向与第二偏光镜片的吸收轴方向相互垂直,并且,第一偏光镜片的吸收轴方向与第一偏振膜的吸收轴方向一致,第二偏光镜片的吸收轴方向与第二偏振膜的吸收轴方向一致。因而,在显示过程中,立体显示装置在第一显示区出射的光线仅能穿过第一偏光镜片,而无法穿过第二偏光镜片,立体显示装置在第二显示区出射的光线仅能穿过第二偏光镜片,而无法穿过第一偏光镜片,从而使第一显示区显示的图像与第二显示区显示的图像分别进入人的不同的眼睛,进入不同眼睛的两个图像经人的大脑融合,在人的大脑中形成立体图像。
在实际应用中,可以将第一偏振膜的吸收轴方向设置为与立体显示装置的长边平行,第二偏振膜的吸收轴方向设置为与立体显示装置的长边垂直,或者,可以将第一偏振膜的吸收轴方向设置为与立体显示装置的长边 垂直,第二偏振膜的吸收轴方向设置为与立体显示装置的长边平行,使得立体显示装置能够适应多种立体眼镜,提高产品的通用性。
在具体实施时,本公开实施例提供的立体显示装置中,上述第一显示区与第二显示区可以至少包括以下三种排布方式:
排布方式一:
如图1所示,第一显示区81与第二显示区82在第一方向X上交替排布;
排布方式二:
如图3所示,第一显示区81与第二显示区82在第二方向Y上交替排布;第二方向Y为与第一方向X交叉的方向;
排布方式三:
如图4所示,第一显示区81与第二显示区82在第一方向X上交替排布,并且,第一显示区81与第二显示区82在第二方向Y上交替排布;第二方向Y为与第一方向X交叉的方向。
也就是说,第一显示区和第二显示区可以在第一方向周期性排布,也可以在第二方向周期性排布,或者也可以在第一方向和第二方向均为周期性排布,当然,第一显示区和第二显示区的排列方式并不局限于上述所列三种,在具体实施时,可以根据实际需要进行设置,此处不做限定。
应该说明的是,在图1、图3和图4中,第一方向X或第二方向Y的箭头可以理解为,表示第一偏振膜或第二偏振膜的吸收轴方向。
在实际应用中,第一显示区中至少包括一个显示器件,第二显示区中至少包括一个显示器件,可以结合第一显示区与第二显示区的排布方式,来确定第一显示区和第二显示区中显示器件的数量和排布。
进一步地,本公开实施例提供的上述立体显示装置中,如图2所示,还可以包括:
第一四分之一波长相位差膜31,形成于第一显示区81的显示器件10与第一偏振膜71之间;
第二四分之一波长相位差膜32,形成于第二显示区82的显示器件10与 第二偏振膜72之间;
第一二分之一波长相位差膜51,形成于第一显示区81的第一四分之一波长相位差膜31与第一偏振膜71之间;
第二二分之一波长相位差膜52,形成于第二显示区82的第二四分之一波长相位差膜32与第二偏振膜72之间。
在第一显示区81内,第一四分之一波长相位差膜31、第一二分之一波长相位差膜51及第一偏振膜71构成圆偏光片,可以减少外界光从第一显示区进入立体显示装置,被显示器件10的第二电极15反射的反射光,从而提高立体显示装置的对比度,进而提高立体显示装置的显示效果。同理,在第二显示区82内,第二四分之一波长相位差膜32、第二二分之一波长相位差膜52及第二偏振膜72构成圆偏光片,可以减少外界光从第二显示区进入立体显示装置,被显示器件10的第二电极15反射的反射光,从而提高立体显示装置的对比度,进而提高立体显示装置的显示效果。
并且,本公开实施中,采用四分之一波长相位差膜、二分之一波长相位差膜及偏振片结合的方式,可以提高圆偏光片的光学性能,使得立体显示装置的抗反射性能更好,此外,为了简化立体显示装置的结构,也可以省去二分之一波长相位差膜。
具体地,本公开实施例提供的上述立体显示装置中,参照图2,第一四分之一波长相位差膜31的慢轴方向与第一偏振膜71的吸收轴方向的夹角为75°;
第二四分之一波长相位差膜32的慢轴方向与第二偏振膜72的吸收轴方向的夹角为75°;
第一二分之一波长相位差膜51的慢轴方向与第一偏振膜71的吸收轴方向的夹角为15°;
第二二分之一波长相位差膜52的慢轴方向与第二偏振膜72的吸收轴方向的夹角为15°。
图5为第一显示区中各光学膜层的简化结构示意图,以下以第一显示 区为例,对立体显示装置的抗反射原理进行详细说明:
外界光(一般为自然光)射向第一偏振膜71时,只有与第一偏振膜71的吸收轴方向c垂直的振动分量才能透过,从而将自然光转换为线偏振光,之后该线偏振光射向第一二分之一波长相位差膜51,由于第一二分之一波长相位差膜51的慢轴方向b与第一偏振膜71的吸收轴方向c的夹角为15°,因而该线偏振光经过第一二分之一波长相位差膜51后,该线偏振光的振动方向偏转30°,此时该线偏振光的振动方向与第一四分之一波长相位差膜31的慢轴方向a的夹角为45°,因而,该线偏振光透过第一四分之一波长相位差膜31后转换为圆偏振光,图中以右旋圆偏振光为例,之后该右旋圆偏振光射入到显示器件10中,被显示器件10中的第二电极反射转换为左旋圆偏振光,之后该左旋圆偏振光再次射入第一四分之一波长相位差膜31,偏振态被改变而转换为振动方向与方向c夹角为30°的线偏振光,该线偏振光再次经第一二分之一波长相位差膜51后,振动方向旋转30°,转换为与方向c平行的线偏振光,因而无法从第一偏振膜71出射,因此,射向该立体显示装置的外界光经显示器件10反射后,不能由出光侧射出,不会影响立体显示装置的显示效果。
第二显示区的抗反射原理与第一显示区类似,此处不再赘述。
具体地,本公开实施提供的上述立体显示装置中,第一四分之一波长相位差膜和第二四分之一波长相位差膜均包括聚合性液晶材料;
如图2所示,立体显示装置,还包括:
第一光配向膜21,形成于第一显示区81的显示器件10与第一四分之一波长相位差膜31之间;
第二光配向膜22,形成于第二显示区82的显示器件10与第二四分之一波长相位差膜32之间;
第一光配向膜21的配向方向与第二光配向膜22的配向方向相互垂直。
通过在第一显示区81的显示器件10之上形成第一光配向膜21,在第二显示区82的显示器件10之上形成第二光配向膜22,并采用聚合性液晶 材料在第一光配向膜21之上形成第一四分之一波长相位差膜31,以及在第二光配向膜22之上形成第二四分之一波长相位差膜32,可以提高立体显示装置的集成度和整体性。第一光配向膜21使第一四分之一波长相位差膜31内的液晶分子沿着第一光配向膜21的配向方向分布,第二光配向膜22使第二四分之一波长相位差膜32内的液晶分子沿着第二光配向膜22的配向方向分布。可以但不仅仅为,第一光配向膜的配向方向与第一偏振膜的吸收轴方向之间的夹角为75°或者105°,第二光配向膜的配向方向与第二偏振膜的吸收轴方向之间的夹角为75°或者105°。
由于第一四分之一波长相位差膜涵盖大部分的可见光,在外界光通过第一偏振膜进入立体显示装置内部后变成线偏振光,线偏振光经过第一四分之一波长相位差膜的旋转后形成出射光,出射光的偏振方向与第一偏振膜的吸收轴平行,无法从第一偏振膜射出,通过第一四分之一波长相位差膜与第一偏振膜配合,减少在外界光从第一显示区进入显示器件内部,被显示器件内的第二电极(金属阴极)反射后从第一偏振片射出的光,从而提高立体显示装置的对比度,进而提高立体显示装置的显示效果。第二四分之一波长相位差膜的作用与第一四分之一波长相位差膜的作用类似,此处不再赘述。
具体地,第一四分之一波长相位差膜和第二四分之一波长相位差膜中的聚合性液晶材料可以但不仅仅为正性光学液晶。
在具体实施时,本公开实施例提供的上述立体显示装置中,第一二分之一波长相位差膜和第二二分之一波长相位差膜均包括聚合性液晶材料;
如图2所示,立体显示装置,还包括:
第三光配向膜41,形成于第一显示区81的第一四分之一波长相位差膜31与第一二分之一波长相位差膜51之间;
第四光配向膜42,形成于第二显示区82的第二四分之一波长相位差膜32与第二二分之一波长相位差膜52之间;
第三光配向膜41的配向方向与第四光配向膜42的配向方向相互垂直。
通过在第一显示区81的第一四分之一波长相位差膜31之上形成第三光配向膜41,在第二显示区82的第二四分之一波长相位差膜32之上形成第四光配向膜42,并采用聚合性液晶材料在第三光配向膜41之上形成第一二分之一波长相位差膜51,以及在第四光配向膜42之上形成第二二分之一波长相位差膜52,可以提高立体显示装置的集成度和整体性。第三光配向膜使第一二分之一波长相位差膜内的液晶沿着第三光配向膜的配向分布,第四光配向膜使第二二分之一波长相位差膜内的液晶沿着第四光配向膜的配向分布。可以但不仅仅为,第三光配向膜的配向方向与第一偏振膜的吸收轴方向之间的夹角为15°或者165°,第四光配向膜的配向方向与第二偏振膜的吸收轴方向之间的夹角为15°或者165°。
通过第一(或第二)四分之一波长相位差膜、第一(或第二)二分之一波长相位差膜与第一(或第二)偏振膜配合,进一步减少在外界光从第一显示区进入显示器件内部,被显示器件中的第二电极(金属阴极)反射后从第一偏振膜射出的光,从而进一步提高立体显示装置的对比度,进而进一步提高立体显示装置的显示效果。
具体地,第一二分之一波长相位差膜和第二二分之一波长相位差膜中的聚合性液晶材料可以但不仅仅为正性光学液晶。
在实际应用中,本公开实施例提供的上述立体显示装置中,第一偏振膜包括二色性染料和聚合性液晶混合物;第二偏振膜包括二色性染料和聚合性液晶混合物;
如图2所示,立体显示装置,还包括:
第五光配向膜61,形成于第一显示区81的第一二分之一波长相位差膜51与第一偏振膜71之间;
第六光配向膜62,形成于第二显示区82的第二二分之一波长相位差膜52与第二偏振膜72之间;
第五光配向膜61的配向方向与第六光配向膜62的配向方向相互垂直。
第五光配向膜使第一偏振膜内的液晶分子沿着第五光配向膜的配向方 向分布,第六光配向膜使第二偏振膜内的液晶分子沿着第六光配向膜的配向分布,第五光配向膜的配向和第六光配向膜的配向方向相互垂直,从而提高立体显示装置的集成度和整体性,能够减少立体显示装置的厚度,使得立体显示装置更加轻薄。
举例来说,第一偏振膜的吸收轴可以设置为0°,第二偏振膜的吸收轴可以设置为90°,第五光配向膜的配向方向可以设置为0°,第六光配向膜的配向方向可以设置为90°,第一二分之一波长相位差膜的慢轴可以设置为15°,第二二分之一波长相位差膜的慢轴可以设置为105°,第三光配向膜的配向方向可以设置为15°,第四光配向膜的配向方向可以设置为105°,第一四分之一波长相位差膜的慢轴可以设置为75°,第二四分之一波长相位差膜的慢轴可以设置为165°,第一光配向膜的配向方向可以设置为75°,第二光配向膜的配向方向可以设置为165°。应该说明的是,此处只是举例说明,在具体实施时,可以根据实际情况来设置各膜层的角度,此处不做限定。
可选地,本公开实施例提供的立体显示装置中,参照图2和图6,还可以包括:用于分隔各显示器件10的像素界定层;
像素界定层,包括:位于相邻的第一显示区81和第二显示区82之间的位置处的遮光部13。
在本公开的实施例中,由于第一显示区81与第二显示区82中的光配向膜的配向方向不同,图6中以第五光配向膜61与第六光配向膜62为例进行示意,由于相邻的第五光配向膜61与第六光配向膜62接触区域的配向方向不同,会导致第五光配向膜与第六光配向膜相邻区域出现液晶排列紊乱,导致降反偏振失效,通过在相邻的第一显示区和第二显示区的像素层之间设置遮光部,可以减少从液晶排列紊乱区域的出射光,从而减少液晶排列紊乱对立体显示装置显示效果的影响。
具体地,本公开实施提供的上述立体显示装置中,上述遮光部包括黑色树脂材料,采用黑色树脂材料制作遮光部,可以使遮光部具有较好的遮光 效果,此外,也可以采用其他不透光材料制作遮光部,此处不做限定。
具体地,本公开实施例提供的立体显示装置中,如图2,显示器件10,包括:位于衬底基板1之上的第一电极16,位于第一电极16背离衬底基板1一侧的第二电极15,以及位于第一电极16与第二电极15之间的发光层11;例如第一电极16可以为阳极,第二电极15可以为阴极,立体显示装置中的各显示器件10的第二电极15为同一膜层。
像素界定层位于衬底基板1与第二电极15之间,采用遮光材料制作位于第一显示区81和第二显示区82位置处的像素界定层,以形成遮光部13,不会对其他膜层产生影响,像素界定层除遮光部13以外的部分可以采用透光材料制作,例如可以采用透明的聚酰亚胺材料。
此外,上述立体显示装置,还可以包括位于衬底基板1与第一电极16之间的驱动电路17,以及位于第二电极15背离衬底基板1一侧的封装层14,其中,驱动电路17可以控制各显示器件10发光,封装层14可以防止水汽和氧气侵入各显示器件10内。
基于同一发明构思,本公开实施例还提供了一种上述立体显示装置的制造方法,由于该制造方法解决问题的原理与上述立体显示装置相似,因此该制造方法的实施可以参见上述立体显示装置的实施,重复之处不再赘述。
本公开实施例提供的上述立体显示装置的制造方法,如图7所示,可以包括以下步骤:

S102、在显示器件背离衬底基板的一侧,形成位于第一显示区的第一偏振膜以及位于第二显示区的第二偏振膜;第一偏振膜的吸收轴方向与第二偏振膜的吸收轴方向相互垂直。
本公开实施例提供的制造方法,通过在显示器件背离衬底基板的一侧,形成位于第一显示区的第一偏振膜以及位于第二显示区的第二偏振膜,相比于将制作好的偏光片直接粘贴到显示器件的表面,本公开实施例可以更容易的在显示器件的出光侧形成吸收轴方向不同的偏振膜,并且可以减小 立体显示装置的厚度,使得立体显示装置更加轻薄且集成度较高。
具体地,同时参照图2,在上述步骤S101中,显示器件10可以包括:依次设置的第一电极16、发光层11及第二电极15,上述立体显示装置,还可以包括位于衬底基板1与第一电极16之间的驱动电路17,以及位于第二电极15背离衬底基板1一侧的封装层14。

参照图10,在第一光配向膜和第二光配向膜之上(及第一光配向层20)涂覆聚合性液晶材料30,并对聚合性液晶材料30进行固化,例如可以采用紫外光照射进行固化,以形成第一四分之一波长相位差膜31和第二四分之一波长相位差膜32,第一四分之一波长相位差膜31和第二四分之一波长相位差膜32内的液晶排布方向如图11所示。
在具体实施时,本公开实施例提供的上述制造方法中,形成第一四分之 一波长相位差膜和第二四分之一波长相位差膜之后,上述步骤S102之前,还可以包括:
参照图12,在第一四分之一波长相位差膜和第二四分之一波长相位差膜之上(即图中膜层30之上)涂覆第二光配向层40,并对第二光配向层40进行预固化和主固化;
参照图13,对位于第一显示区的第二光配向层进行取向处理,以形成第三光配向膜41,具体地,可以采用掩膜版对第二显示区进行遮挡,采用紫外光照射第一显示区中的第二光配向层,以完成对第一显示区中的第二光配向层的取向处理;
对位于第二显示区的第二光配向层进行取向处理,以形成第四光配向膜42,且第三光配向膜41的配向方向与第四光配向膜42的配向方向相互垂直;具体地,可以采用掩膜版对第一显示区进行遮挡,采用紫外光照射第二显示区中的第二光配向层,以完成对第二显示区中的第二光配向层的取向处理;
参照图14,在第三光配向膜和第四光配向膜之上(即图中膜层40之上)涂覆聚合性液晶材料50,并对聚合性液晶材料50进行固化,例如可以采用紫外光照射进行固化,以形成第一二分之一波长相位差膜51和第二二分之一波长相位差膜52,第一二分之一波长相位差膜51和第二二分之一波长相位差膜52内的液晶排布方向如图15所示。
具体地,本公开实施例提供的上述制造方法中,上述形成第一二分之一波长相位差膜和第二二分之一波长相位差膜之后,上述步骤S102之前,还可以包括:
参照图16,在第一二分之一波长相位差膜和第二二分之一波长相位差膜之上(即图中膜层50之上)涂覆第三光配向层60,并对第三光配向层60进行预固化和主固化;
参照图17,对位于第一显示区的第三光配向层进行取向处理,以形成第五光配向膜61;具体地,可以采用掩膜版对第二显示区进行遮挡,采用紫外光照射第一显示区中的第三光配向层,以完成对第一显示区中的第三光配向 层的取向处理;
对位于第二显示区的第三光配向层进行取向处理,以形成第六光配向膜62,且第五光配向膜61的配向方向与第六光配向膜62的配向方向相互垂直;具体地,可以采用掩膜版对第一显示区进行遮挡,采用紫外光照射第二显示区中的第三光配向层,以完成对第二显示区中的第三光配向层的取向处理;
上述步骤S102,可以包括:
参照图18,在第五光配向膜和第六光配向膜之上(即图中膜层60之上)涂覆二色性染料和聚合性液晶混合物70,并对二色性染料和聚合性液晶混合物70进行固化,以形成第一偏振膜71和第二偏振膜72,第一偏振膜71和第二偏振膜72内的液晶分子和二色性染料混合物的排布方向如图19所示。
二色性染料会对平行于其吸收轴方向的光吸收,垂直于其吸收轴方向的光透过。二色性染料显示根据其染料结构确定各种吸光特征,二色性染料通常吸收特定波长(诸如,红、蓝及黄)使得难以使用单一染料展示黑色。为此,一般混合复数种二色性染料中之三种或三种以上以展示黑色。一般而言,认为可见光之波长范围在380nm至780nm内,且若光吸收在此范围中恒定,则认为其系"黑色"。然而,考虑到暗适应性相对于人类视觉敏感性之标准视觉敏感性曲线,吸光令人合意地在400nm至650nm之波长范围内恒定。因此二色性染料的选取有以下,第一点,可选择吸收之波长色散在450nm至650nm的二色性染料组合物,第二点,二色性染料在液晶中得溶解度足够高。
本公开实施中,通过在显示器件之上形成第一(或第二)四分之一波长相位差膜、第一(或第二)二分之一波长相位差膜及第一(或第二)偏振膜,提高了立体显示装置的集成度和整体性。
进一步地,本公开实施例提供的上述制造方法中,参照图2和图6,还可以包括:采用黑色树脂材料,在衬底基板1之上形成位于相邻的第一显示区81和第二显示区82之间的位置处的遮光部13。采用黑色树脂材料制作遮光部,可以使遮光部具有较好的遮光效果,此外,也可以采用其他不透光材 料制作遮光部,此处不做限定。
在本公开的实施例中,由于第一显示区81与第二显示区82中的光配向膜的配向方向不同,图6中以第五光配向膜61与第六光配向膜62为例进行示意,由于相邻的第五光配向膜61与第六光配向膜62接触区域的配向方向不同,会导致第五光配向膜与第六光配向膜相邻区域出现液晶排列紊乱,导致降反偏振失效,通过在相邻的第一显示区的像素层和第二显示区的像素层之间设置遮光部,可以减少从液晶排列紊乱区域的出射光,从而减少液晶排列紊乱对立体显示装置显示效果的影响。
本公开实施例提供的立体显示装置及其制造方法,通过在显示器件背离衬底基板的一侧,形成位于第一显示区的第一偏振膜以及位于第二显示区的第二偏振膜,相比于将制作好的偏光片直接粘贴到显示器件的表面,本公开实施例可以更容易的在显示器件的出光侧形成吸收轴方向不同的偏振膜,并且可以减小立体显示装置的厚度,使得立体显示装置更加轻薄且集成度较高。
以上描述仅为本公开的较佳实施例以及对所运用技术原理的说明。本领域技术人员应当理解,本公开中所涉及的公开范围,并不限于上述技术特征的特定组合而成的技术方案,同时也应涵盖在不脱离公开构思的情况下,由上述技术特征或其等同特征进行任意组合而形成的其它技术方案。例如上述特征与本公开中公开的(但不限于)具有类似功能的技术特征进行互相替换而形成的技术方案。
