 本发明的实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其它实施例，都属于本申请保护的范围。此外，应当理解的是，此处所描述的具体实施方式仅用于说明与解释本申请，并不用于限制本申请。此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个所述特征。
本申请提供一种3D显示装置，以下进行详细说明。需要说明的是，以下实施例的描述顺序不作为对本申请实施例优选顺序的限定。
请参阅图1，图1是本申请提供的3D显示装置的第一结构示意图。在本申请中，3D显示装置100包括多条发光纤维10和多条电极走线20。多条发光纤维10间隔排布，且设置在不同平面内。多条电极走线20间隔排布，且与相应的发光纤维10交叉接触设置，以形成立体网络结构。
由此，本申请利用发光纤维10和电极走线20接触交叉，形成立体网络结构。发光纤维10与电极走线20之间的每一交叉点Q即为一像素点。每一交叉点Q的发光状态由相应的发光纤维10以及电极走线20控制。因此，通过向发光纤维10和电极走线20施加不同的驱动电压，可以使相应的交叉点Q发光，从而使3D显示装置100显示出更全面真实的立体图像。
请同时参阅图2和图3，图2是本申请提供的发光纤维的一种结构示意图。图3是图2所示的发光纤维沿AA’处的第一剖面结构示意图。在本申请中，发光纤维10包括由内向外同轴设置的导电层11和绝缘介电层12。绝缘介电层12中设有发光材料13。
在本申请中，导电层11和电极走线20的材料可以是铜、铝、钼等金属导电材料。导电层11和电极走线20的材料也可以是有机导电聚合物、氧化铟镓锌、石墨烯、离子导电水凝胶、氧化铟镓锌、氧化铟镓锡、氧化锑锡等透明导电材料。其中，有机导电聚合物可以是聚(3,4-亚乙基二氧噻吩)等。离子导电水凝胶可以是氯化铝-聚丙烯酰胺导电水凝胶等。氯化铝-聚丙烯酰胺导电水凝胶表现出稳定的可拉伸性和足够的离子电导率。
在本申请中，介电层12具有绝缘特性。当发光材料13为分散的发光颗粒时，介电层12的材料需要能够分散发光材料颗粒。介电层12的材料可以是聚二甲基硅氧烷(Polydimethylsiloxane, PDMS)、聚酰亚胺、聚对苯二甲酸乙二酯(Polyethylene terephthalate, PET)等透明聚合物材料。介电层12的厚度一般在5μm到500μm之间。比如，介电层12的厚度可以是5μm、50μm、100μm、250μm、400μm、500μm等，在此不一一赘述。
具体的，介电层12的尺寸可以基于所选的发光材料13的颗粒粒径、以及显示的分别率进行调节。可以理解的是，介电层12的厚度越小，发光纤维10的横截面尺寸越小。则3D显示装置100的分辨率可以做得更高。此外，介电层12的厚度要大于掺杂其中的发光材料13的颗粒粒径，以便起到绝缘保护的作用。
在本申请中，发光材料13主要包括基体材料和发光中心两部分。基体材料通常是II-VI族化合物、三元硫化物、氧化物、氟化物等。II-VI族化合物可以是ZnS、ZnSe、CaS、SrS等。三元硫化物可以是CaGaS 4、SrGa 2S 4等。氧化物可以是Zn 2Si 1-xCe xO 4、ZnGa 2O 4、Ga 2O 3等。发光中心的元素通常为过渡金属、稀土金属等。过渡金属可以是锰、铜、铬等。稀土金属可以是铈、镨、铕、铽等。比如，发光材料13可以是ZnS:Mn、SrS:Ce、SrS:Cu、SrS:Ag/Cu、掺杂稀土元素的ZnS、硫代乙醇酸盐、其它碱土金属硫化物等。
其中，发光材料13的颗粒尺寸通常在50nm到10μm之间。比如，发光材料13的颗粒尺寸可以是50nm、100nm、50nm、500nm、1μm、5μm、10μm等，在此不一一赘述。
其中，不同种类的发光材料13具有不同的发光颜色。对于同一种发光材料13，不同的颗粒尺寸也可能具有不同的发光颜色。本申请可以在介电层12中设置同一种发光材料13，也可以设置不同种类的发光材料13。
可以理解的是，上述发光材料13采用电致发光的方式进行发光。在申请一些实施例中，还可以在绝缘介质层12中掺杂光致发光材料，以利用能量转移过程实现光致发光材料的发光，从而获得更丰富的发光颜色。其中，光致发光材料可以是量子点、上转换纳米颗粒、荧光粉等，在此不一一赘述。
在本申请一些实施例中，3D显示装置100可以是透明的，以达到更好的显示效果。对此，可将发光纤维10设置为透明发光纤维。也即，导电层11和绝缘介电层12均可由上述的透明材料制成。此外，电极走线20也可由透明材料制成，可以进一步提高3D显示装置100的透明度。当然，电极走线20的材料也可以是铜、铝、钼等不透明导电金属。当电极走线20由不透明材料制成时，3D显示装置100的开口率（透明度）由编织的密度决定。
进一步的，导电层11、绝缘介质层12以及电极走线20均由可拉伸材料制成。比如，导电层11和电极走线20的材料均为离子导电水凝胶等可拉伸导电材料，以及绝缘介电层12的材料为PDMS等可拉伸介电材料。从而获得可拉伸的柔性3D显示装置100。则通过拉伸发光纤维10和电极走线20可以改变3D显示装置100的大小。
请同时参阅图3和图4，图4是本申请提供的发光纤维和电极走线的发光原理图。在本申请实施例中，发光纤维10仅包括导电层11和绝缘介电层12。发光纤维10的结构简单，生产效率更高，且可以降低生产成本。但是基于电致发光的原理，当使用图3所示的发光纤维10时，还需要额外设置电极走线20与发光纤维10共同作用发光。
其中，导电层11和电极走线20分别作为电极，以向发光材料13供电。具体的，可向第一透明导电层11和电极走线20施加交流电。当电压足够高时，电子从绝缘-半导体（介电层12和发光材料13）界面层注射到发光材料13中。注入电子在强电场中获得能量，这些高能电子或热电子通过碰撞而激发充当“发光中心”的离子(比如Cu +)，处于激发态的发光中心通过发射光子回到基态，穿过发光材料13的电子被陷在另一侧的绝缘-半导体界面层。当交流电的电压反向时，同样的过程再重复发生一次。于是，第一透明导电层11和电极走线20的交叉点Q便能够在交流电场作用下发光。交叉点Q的亮度可以通过提高交流电的电压值和频率来提高。
具体的，交流电的电压值范围为0.1-200V，频率为50Hz-50KHz。比如，交流电的电压值可以是0.1V、5V、50V、100V、200V等。频率可以为50Hz、100Hz、10KHz、300KHz、50KHz等。
其中，由于多条电极走线20分别与发光纤维10接触形成交叉点Q，且仅在交叉点Q处可实现发光。因此，通过控制施加至发光纤维10和电极走线20的电压，可以控制不同的交叉点Q发光。也即，通过给特定的像素点加电实现该像素点的点亮发光，进而由立体的像素点组成所需的立体图像。同时，通过调整发光纤维10与电极走线20的排布密度，可以调整3D显示装置100的分辨率。
请继续参阅图3，在本实施例中，发光材料13包括多个发光颗粒。发光颗粒均匀掺杂在绝缘介电层12中。其中，发光材料13的掺杂浓度为1mg/mL-1000mg/mL。比如，发光材料13的掺杂浓度可以是1mg/mL、10mg/mL、100mg/mL、500mg/mL、800mg/mL、1000mg/mL等，在此不一一赘述。
由于发光颗粒的粒径一般较小，本实施例直接将发光颗粒掺杂在绝缘介电层12中，可以进一步提高发光纤维10的透明度。
请同时参阅图2和图5，图5是图2所示的发光纤维沿AA’处的第二剖面结构示意图。与图3所示的发光纤维10的不同之处在于，在本实施例中，发光材料13为一发光层131。绝缘介电层12包括第一介电层121和第二介电层122。发光层131、第一介电层121以及第二介电层122均同轴设置。第一介电层121包覆在导电层11的外侧。发光层131包覆在第一介电层121的外侧。第二介电层122包覆在发光层131的外侧。
本实施例在发光纤维10中设置发光层131，使得绝缘介质层12的材料选择范围更大，不需要考虑对发光颗粒的分散性。此外，发光层131完全覆盖第一导电层11，使得发光纤维10处处均可导电，可进一步提高3D显示装置100的像素密度。
在本申请中，发光纤维10和电极走线20的数量可根据3D显示装置100的尺寸以及分辨率进行设计，本申请对此不作具体限定。
在本申请中，多条发光纤维10可以沿同一方向延伸，也可以沿不同方向延伸，只要保证3D显示装置100中的任意两条发光纤维10不相交即可。每条电极走线20可以与一条发光纤维10接触相交，也可以与多条发光纤维10接触相交，具体可根据发光纤维10和电极走线20的排布方式进行设定。此外，电极走线20可以与发光纤维10垂直相交，也可以只相交不垂直。
具体的，请继续参阅图1，在本申请一些实施例中，沿第一方向Z，3D显示装置100具有多个相互平行的显示平面101。在每一显示平面101内，多条发光纤维10沿第二方向X排布。多条电极走线20沿第三方向Y排布。第二方向X和第三方向Y交叉。第二方向X和第三方向Y均垂直于第一方向Z。
本实施例将发光纤维10和电极走线20沿着第一方向Z、第二方向X以及第三方向Y，在空间内规则排布，从而获得规则排布的像素矩阵。规则排布的像素点使得3D显示装置100显示亮度更均匀，从而达到更好的显示效果。此外，由于各像素点均匀排布，更易于通过控制施加至相应的发光纤维10和电极走线20的电压，控制像素点的发光，避免各驱动电压信号之间发生干扰。此外，当3D显示装置100为透明显示装置时，规则排布的发光纤维10和电极走线20可以进一步提高3D显示装置100的外观美观性。
可选的，第二方向X垂直于第三方向Y。也即，发光纤维10与电极走线20垂直相交。本实施例可以进一步提高发光纤维10与电极走线20的排布规整性。此外，由于发光纤维10与电极走线20可以通过编织的方式交叉设置。因此，发光纤维10与电极走线20垂直相交，可以提高发光纤维10与电极走线20之间的稳定性，避免发光纤维10与电极走线20之间发生晃动。
在本申请一些实施例中，在每一显示平面101内，多条电极走线20可以覆盖在相应的发光纤维10上，以实现与发光纤维10的接触相交。本实施例可以简化发光纤维10与电极走线20的结构，进而简化工艺制程。
在本申请另一些实施例中，在每一显示平面101内，可以利用编织的方式将多条电极走线20与多条相应的发光纤维10编织在一起，以实现电极走线20与发光纤维10的接触相交。本实施例可以提高发光纤维10与电极走线20的结构稳定性，避免发光纤维10与电极走线20在3D显示装置100的移动过程中晃动，发生接触不良的问题。
可以理解的是，本申请提供的3D显示装置100用于显示立体的图像。该立体的图像可以由同一颜色构成，也可以由不同的颜色构成。
对此，在本申请中，多条发光纤维10可以显示同一颜色。仅需要通过控制施加至发光纤维10和电极走线20的电压值大小，即可控制不同交叉点Q的亮度，从而实现立体的图像显示。
当然，在本申请中，相邻的发光纤维10可以发射不同颜色的光。该设置通过显示颜色以及显示亮度的双重显示效果，可使得3D显示装置100显示的图像更加立体。
进一步的，在本申请实施例中，发光纤维10包括红色发光纤维、绿色发光纤维以及蓝色发光纤维。在同一显示平面101内，红色发光纤维、绿色发光纤维以及蓝色发光纤维以任一排列组合重复排列。在相邻显示平面101内，发光纤维一一对应设置。从而获得规则排布的彩色像素矩阵，实现彩色的立体图像显示。
具体的，在同一显示平面101内，红色发光纤维、绿色发光纤维以及蓝色发光纤维可以以RGB、RBG、BGR、BRG、GRB、GBR等排列组合中的任一排列组合为单位重复排列，本申请对此不作具体限定。
当然，本申请并不限于此。3D显示装置100还可以在RGB像素排列的基础上增加白色像素点，形成RGBW像素排列架构。也即，增加白色发光纤维。白色发光纤维的加入，使得3D显示装置100的透光率得到明显提升，3D显示装置100的亮度也在传统RGB像素排列架构的基础上得到提升。
请继续参阅图1，在本申请中，3D显示装置100还包括相对设置的第一基板31和第二基板32，以及相对设置的第三基板33和第四基板34。第一基板31、第二基板32、第三基板33以及第四基板34首尾相接。
其中，每一发光纤维10的一端固定在第一基板31上。每一发光纤维10的另一端固定在第二基板32上。每一电极走线20的一端固定在第三基板33上。每一电极走线20的另一端固定在第四基板34上。
其中，第一基板31、第二基板32、第三基板33以及第四基板34可以由透明材料制成，以便从3D显示装置100外部的不同角度观看立体图像。比如，第一基板31、第二基板32、第三基板33以及第四基板34可以是透明玻璃基板。
其中，第一基板31、第二基板32、第三基板33以及第四基板34的平面结构可以是长方形、正方形、弧形等。则第一基板31、第二基板32、第三基板33以及第四基板34首尾相接形成的立体结构可以是正方体、长方体或球体。从而使得3D显示装置100在不发光时呈现为正方体或长方体或球体等状态，提高3D显示装置100的外观美观性。
其中，发光纤维10可以通过粘贴、卡和等方式固定在第一基板31和第二基板32之间。电极走线20也可以通过粘贴、卡和等方式固定在第三基板33和第四基板34之间。
本申请通过设置第一基板31、第二基板32、第三基板33以及第四基板34，可以将发光纤维10和电极走线20稳定地固定在3D显示装置100中，避免发光纤维10和电极走线20在3D显示装置100的移动过程中发生晃动而产生接触不良的问题。从而提高3D显示装置100的显示稳定性。
进一步的，在本申请中，3D显示装置100还包括相对设置的第五基板35和第六基板36。第一基板31、第二基板32、第三基板33、第四基板34、第五基板35以及第六基板36形成一封闭结构。第五基板35和第六基板36均由透明材料制成。
本申请设置第五基板35和第六基板36，从而利用第一基板31、第二基板32、第三基板33、第四基板34、第五基板35以及第六基板36形成一封闭结构，作为3D显示装置100的外壳，可以保护3D显示装置100中的显示结构。进一步提高3D显示装置100的稳定性。
请参阅图6，图6是本申请提供的3D显示装置的第二结构示意图。与图1所示的3D显示装置100的不同之处在于，在本实施例中，第一基板31、和/或第二基板32上设置有第一过孔310。第三基板33和/或第四基板34上设置有第二过孔330。每一发光纤维10通过第一过孔310延伸至第一基板31或第二基板32的外侧。每一电极走线20通过第二过孔330延伸至第三基板33或第四基板34的外侧。
可以理解的是，本申请需要通过向发光纤维10和电极走线20施加电压，使得相应的交叉点Q发光，从而达到立体显示的效果。因此，需要将发光纤维10和电极走线20的端部引出，以便于施加电压。
具体的，当3D显示装置100的分辨率较低时，发光纤维10的分布密度较小。因此，可以仅在第一基板31或第二基板32上设置第一过孔310，以将发光纤维10的端部引出至第一基板31或第二基板32的外侧。同理，电极走线20的分布密度较小。因此，可以仅在第三基板33或第四基板34上设置第二过孔330，以将发光纤维10的端部引出至第三基板33或第四基板34的外侧。从而使得延伸出的发光纤维10或电极走线20仅位于3D显示装置100的一个侧面，提高电路的集中性。
当3D显示装置100的分辨率较高时，发光纤维10的分布密度较大。由于第一基板31或第二基板32的尺寸有限，本申请将多个第一过孔310分别设置在第一基板31和第二基板32上。一方面，可以提供足够数量的第一过孔310。第二方面，避免相邻发光纤维10在穿过第一过孔310时，发生交叉短路。同理，第二过孔330的设置亦然，在此不再赘述。
其中，第一过孔310的孔径与发光纤维10的横截面的径向尺寸相适配。在保证发光纤维10顺利穿过第一过孔310的同时，使得发光纤维10可稳定地卡和在第一过孔310中。同理，第二过孔330的孔径与电极走线20的横截面的径向尺寸相适配，在此不再赘述。
进一步的，第一基板31、第二基板32、第三基板33以及第四基板34的外侧可设置驱动芯片40。驱动芯片40与相应的发光纤维10或电极走线20连接，以提供驱动电压至发光纤维10或电极走线20。需要说明的，图6仅为示例，未将所有第一过孔310、第二过孔330、延伸至外侧的发光纤维10以及电极走线20画出，但不能理解为对本申请的限定。
可选的，请参阅图7，图7是本申请提供的3D显示装置中第一基板的一种结构示意图。与图6所示的3D显示装置100的不同之处在于，在本实施例中，第一基板31包括衬底基板311、第一导电引脚312以及第一连接走线313。每一发光纤维10的一端与相应的第一导电引脚312电性连接。发光纤维10通过第一导电引脚312与第一连接走线313。
进一步的，3D显示装置100还包括驱动芯片40。驱动芯片40分别与发光纤维10以及电极走线20连接，用于提供驱动电压至发光纤维10以及电极走线20。
其中，发光纤维10可以与电极走线20连接至同一驱动芯片40。发光纤维10也可以与电极走线20分别连接至不同的驱动芯片40。驱动芯片40的数量可根据发光纤维10以及电极走线20的数量设置。其中，驱动芯片40可以设置在第一基板31、第二基板32、第三基板33或第四基板34上，也可以设置在3D显示装置100的其它位置处，本申请对此不作具体限定。
其中，每一发光纤维10的一端可以通过导电胶与第一导电引脚312电性连接。第一导电引脚312和第一连接走线313以及驱动芯片40可以设置在第一基板31的内侧壁或外侧壁。当第一导电引脚312、第一连接走线313以及驱动芯片40设置在第一基板31的外侧壁时，第一导电引脚312贯穿第一基板31，以实现发光纤维10与第一连接走线313之间的连接。
本实施例通过在第一基板31上设置第一导电引脚312，可以避免将发光纤维10引出第一基板31的外侧，从而更好的保护发光纤维10，提高3D显示装置100的寿命。
当然，第二基板32上也可设置第一导电引脚312和第一连接走线313。具体可参阅第一基板31的结构，在此不再赘述。
同理，请参阅图8，图8是本申请提供的3D显示装置中第三基板的一种结构示意图。在本实施例中，第三基板33包括衬底基板331、第二导电引脚332以及第二连接走线333。每一电极走线20的一端与相应的第二导电引脚332电性连接。电极走线20通过第二导电引脚332与第二连接走线333连接。
其中，每一电极走线20的一端可以通过导电胶与第二导电引脚332电性连接。第二导电引脚332和第二连接走线333以及驱动芯片40可以设置在第三基板33的内侧壁或外侧壁。当第二导电引脚332、第二连接走线333以及驱动芯片40设置在第三基板33的外侧壁时，第二导电引脚332贯穿第三基板33，以实现电极走线20与第二连接走线333之间的连接。
本实施例通过在第三基板33上设置第二导电引脚332，可以避免将电极走线20引出第三基板33的外侧，从而更好的保护电极走线20，提高3D显示装置100的寿命。
当然，第四基板34上也可设置第二导电引脚332和第二连接走线333。具体可参阅第三基板33的结构，在此不再赘述。
以上对本申请提供的3D显示装置进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的方法及其核心思想；同时，对于本领域的一般技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
