 本发明的实施方式
下面将结合本申请中的附图，对本申请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他实施例，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和解释本申请，并不用于限制本申请。在本申请中，在未作相反说明的情况下，使用的方位词如“上”和“下”通常是指装置实际使用或工作状态下的上和下，具体为附图中的图面方向；而“内”和“外”则是针对装置的轮廓而言的。
本申请提供一种双面显示面板及双面显示装置。以下分别进行详细说明。需说明的是，以下实施例的描述顺序不作为对实施例优选顺序的限定。
请同时参阅图1和图2。图1是本申请提供的双面显示面板的第一种结构示意图。图2是本申请提供的双面显示面板的第一种像素排列示意图。双面显示面板10包括支撑层1以及多个子像素组2。子像素组2设置在支撑层1上。每个子像素组2中均包括多种颜色的子像素2’。相邻两个同色子像素2’分别对应设置为第一像素结构10a和第二像素结构10b。
第一像素结构10a包括在支撑层1上依次层叠设置的第一阳极层211、第一发光功能层221以及第一阴极层231。第二像素结构10b包括在支撑层1上依次层叠设置的第二阴极层232、第二发光功能层222以及第二阳极层212。
可以理解的是，OLED显示面板的发光功能层通过阴极和阳极出射的光线在光谱上存在差异。在一些双面显示面板中，通过阴极出射的光线亮度比通过阳极出射的光线亮度大50%左右。因此，图1所示的双面显示面板10将相邻子像素组2中的同色子像素2’分别对应设置为第一像素结构10a和第二像素结构10b，使双面显示面板10在一显示面发出的光线为两种像素结构出射光线的平均。则在一个局部区域内，同色子像素2’朝同一侧发光的亮度、色度、视角等均是统一的，从而保证了双面显示面板10两侧的显示效果是统一的。
其中，第一发光功能层221包括第一红色发光功能层221a、第一绿色发光功能层221b以及第一蓝色发光功能层221c。第二发光功能层222包括第二红色发光功能层222a、第二绿色发光功能层222b以及第二蓝色发光功能层222c。在支撑层1上形成顺序排布的第一蓝色子像素B1、第一绿色子像素G1、第一红色子像素R1、第二蓝色子像素B2、第二绿色子像素G2以及第二红色子像素R2。
以图2所示的像素排列为示例进行说明。子像素组2中包括红色子像素R、绿色子像素G以及蓝色子像素B。双面显示面板10相邻两个子像素组2中的红色子像素R分别对应以第一像素结构10a和第二像素结构10b设置，以形成第一红色子像素R1和第二红色子像素R2。在远离支撑层1侧的显示面，第一红色子像素R1的亮度更高。在靠近支撑层1侧的显示面，第二红色子像素R2的亮度更高。因此，两面的红色子像素R的发光亮度均是第一红色子像素R1和第二红色子像素R2发光亮度的平均。由此，可以实现双面显示面板10在两个显示面亮度、色度以及视角的统一。
需要说明的是，本申请的图2提供的双面显示面板10的像素排布顺序仅为示意。图2所示的像素排布是以蓝色、绿色、红色顺序排布为例进行说明。实际上，像素排布还可以是蓝色、红色、绿色的顺序，或红色、蓝色、绿色的顺序等。本申请对此不做限制，在此不再赘述。
其中，如图1和图2所示。第一红色子像素R1是指以第一像素结构10a形成的红色子像素R。第二红色子像素R2是指以第二像素结构10b形成的红色子像素。第一绿色子像素G1是指以第一像素结构10a形成的绿色子像素G。第二绿色子像素G2是指以第二像素结构10b形成的绿色子像素G。第一蓝色子像素B1是指以第一像素结构10a形成的蓝色子像素B。第二蓝色子像素B2是指以第二像素结构10b形成的蓝色子像素B。红色子像素R、绿色子像素G以及蓝色子像素B均具有长边2a和短边2b，红色子像素R的长边2a、绿色子像素G的长边2a与蓝色子像素B的长边2a相互平行设置。
其中，支撑层1是用于承载子像素组2的基体构件。在一些实施例中，支撑层1可以是阵列基板。阵列基板包括层叠设置的基板、薄膜晶体管层以及像素定义层。阵列基板的结构与制程是本领域技术人员所熟知的技术手段，在此不再赘述。
其中，基板采用的材料为聚合物材料，具体地，柔性衬底采用的材料可以为聚酰亚胺（Polyimide, PI）、聚乙烯（Polyethylene, PE）、聚丙烯（Polypropylene, PP）、聚苯乙烯（Polystyrene, PS）、聚对苯二甲酸乙二醇酯（Polyethylene glycol terephthalate, PET）或聚萘二甲酸乙二醇酯（Polyethylene naphthalate two formic acid glycol ester, PEN）。聚合物材料的柔韧性好、质量轻、耐冲击，适用于柔性显示面板。其中，聚酰亚胺还能够实现良好的耐热性和稳定性。
其中，双面显示面板10中还包括透明显示区（图中未示出）。在双面显示面板10中，未设置第一发光功能层221和第二发光功能层222的区域为透明显示区。透明显示区中同样设置有支撑层、第一阳极层和第一阴极层，或支撑层、第二阳极层和第二阴极层。
可以理解的是，透明显示器可以实现透明显示。在透明显示器中设置有透明显示区。设置透明显示区使显示面板更容易实现双面显示。将本申请中的双面显示面板10设置透明显示区可以实现透明显示器的双面显示。对于透明显示器中透明显示区的结构是本领域技术人员所述所熟知的技术手段，在此不再赘述。
请参阅图3，图3是本申请提供的双面显示面板的第二种结构示意图。在一些实施例中，第一发光功能层221包括第一空穴注入层2211、第一空穴传输层2212、第一发光层2213、第一电子传输层2214以及第一电子注入层2215。第二发光功能层222包括第二空穴注入层2221、第二空穴传输层2222、第二发光层2223、第二电子传输层2224以及第二电子注入层2225。第一阳极层211包括第一透明电极层2111、第一金属层2112以及第二透明电极层2113。第二阳极层212包括第三透明电极层2121、第二金属层2122以及第四透明电极层2123。
第一阳极层211和第二阳极层212均采用透明电极层/金属层/透明电极层的叠层结构进行设置。并且第一发光功能层221和第二发光功能层222均包括空穴注入层、空穴传输层、发光层、电子传输层以及电子注入层结构。本申请提供的第一像素结构10a与第二像素结构10b采用完全上下对称的结构，因此可以平均双面显示面板10两侧的出光亮度。
在一些实施例中，第一发光功能层221和第二发光功能层222还可以包括空穴阻挡层和电子阻挡层。第一发光功能层221和第二发光功能层222的结构是本领域技术人员所熟知的技术手段，在此不再赘述。
其中，第一透明电极层2111、第二透明电极层2113、第三透明电极层2121以及第四透明电极层2123采用的材料可以为铟镓锌氧化物(IGZO)、铟锌锡氧化物（IZTO）、铟镓锌锡氧化物（IGZTO）、铟锡氧化物（ITO）、铟锌氧化物（IZO）、铟铝锌氧化物（IAZO）、铟镓锡氧化物（IGTO）或锑锡氧化物（ATO）中的任一种。以上材料具有很好的导电性和透明性，并且厚度较小，不会影响显示面板的整体厚度。同时，还可以减少对人体有害的电子辐射及紫外、红外光。
其中，第一金属层2112、第二金属层2122、第一阴极层231以及第二阴极层232采用的材料为银（Ag）、铝（Al）、镍（Ni）、铬（Cr）、钼（Mo）、铜（Cu）、钨（W）或钛（Ti）中的任一种。银、铝、铜等金属的导电性好，成本较低，在保证阳极的导电性的同时可以降低生产成本。
在一种实施例中，第一透明电极层2111、第二透明电极层2113、第三透明电极层2121以及第四透明电极层2123采用的材料为ITO。第一金属层2112、第二金属层2122、第一阴极层231以及第二阴极层232采用的材料为Ag。
请参阅图4，图4是本申请提供的双面显示面板的第二种像素排列示意图。在相邻两个子像素组2中，同色子像素2’呈轴对称排布。
其中，如图1和图4所示，每个子像素组2均包括红色子像素R、绿色子像素G以及蓝色子像素B。第一红色子像素R1是指以第一像素结构10a形成的红色子像素R。第二红色子像素R2是指以第二像素结构10b形成的红色子像素R。第一绿色子像素G1是指以第一像素结构10a形成的绿色子像素G。第二绿色子像素G2是指以第二像素结构10b形成的绿色子像素G。第一蓝色子像素B1是指以第一像素结构10a形成的蓝色子像素B。第二蓝色子像素B2是指以第二像素结构10b形成的蓝色子像素B。红色子像素R、绿色子像素G、蓝色子像素B均具有长边2a和短边2b，红色子像素R与绿色子像素G的短边2b均与蓝色子像素B的长边2a平行设置。
进一步的，如图4所示，蓝色子像素B的长边2a的长度等于红色子像素R与绿色子像素G的短边2b的长度之和。具体的，第一蓝色子像素B1的长边2a的长度等于第一红色子像素R1与第一绿色子像素G1的短边2b的长度之和。
图4所示的像素排列方式能够减小子像素2’的布局空间，从而增大双面显示面板10的分辨率。这种像素排列的双面显示面板10可以适用各种场景，应用范围更广。同时，这样的像素排列可以有效降低双面显示面板10的显示屏温度及显示器件温度，极大提高双面显示面板10的信赖性，提高显示品质。
请参阅图5，图5是本申请提供的双面显示面板的第三种像素排列示意图。在相邻两个子像素组2中，同色子像素2’呈中心对称排布。
图5所示的像素排列方式能够使子像素组2利用与之相邻的子像素组2显示更多的信息。例如，第一红色子像素R1、第一绿色子像素G1与第二蓝色子像素B2可以形成三原色混光，进行彩色画面显示。这样就达到了低分辨率像素排布完整显示高分辨率图像信息的功能。
请同时参阅图6和图7，图6是本申请提供的双面显示面板的第三种结构示意图。图7是本申请提供的双面显示面板的第四种像素排列示意图。双面显示面板10包括支撑层1以及多个子像素组2，子像素组2设置在支撑层1上。每个子像素组2中均包括多种颜色的子像素2’。每个子像素2’具有数量相等的第一子像素单元21和第二子像素单元22。第一子像素单元21对应设置为第一像素结构10a，第二子像素单元22对应设置为第二像素结构10b。
第一像素结构10a包括在支撑层1上依次层叠设置的第一阳极层211、第一发光功能层221以及第一阴极层231。第二像素结构10b包括在支撑层1上依次层叠设置的第二阴极层232、第二发光功能层222以及第二阳极层212。
如上所述，OLED显示面板的发光功能层通过阴极和阳极出射的光线在光谱上存在差异。在一些双面显示面板中，通过阴极出射的光线亮度比通过阳极出射的光线亮度大50%左右。因此，图6所示的双面显示面板10将子像素2’拆分为两个子像素单元，第一子像素单元21和第二子像素单元22分别对应设置为第一像素结构10a和第二像素结构10b。使双面显示面板10在一显示面发出的光线为两种像素结构出射光线的平均。则在一个局部区域内，同色子像素2’朝同一侧发光的亮度、色度、视角等均是统一的，从而保证了双面显示面板10两侧的显示效果是统一的。
图6所示的双面显示面板10在子像素2’维度上进行了第一像素结构10a和第二像素结构10b的结构设计。使得每个子像素2’均能在各显示面实现亮度、色度、视角等的统一。具体的实现原理与图1所示的双面显示面板10相同，在此不再赘述。
其中，第一发光功能层221包括第一红色发光功能层221a、第一绿色发光功能层221b以及第一蓝色发光功能层221c。第二发光功能层包括第二红色发光功能层222a、第二绿色发光功能层222b以及第二蓝色发光功能层222c。在支撑层1上形成顺序排布的蓝色子像素、绿色子像素以及红色子像素。其中，蓝色子像素中包括第一蓝色子像素单元B3和第二蓝色子像素单元B4。绿色子像素中包括第一绿色子像素单元G3和第二绿色子像素单元G4。红色子像素中包括第一红色子像素单元R3和第二红色子像素单元R4。
在制程条件允许的情况下，还可以将一个子像素2’拆分为两个第一子像素单元21和两个第二子像素单元22。或者，将一个子像素2’拆分为三个第一子像素单元21和三个第二子像素单元22甚至更多。只要保证第一子像素单元21与第二子像素单元22的数量相等，即可保证双面显示面板10两个显示面的发光均一性。本申请对此不做限制。
需要说明的是，图7所示的像素排布示意图是以第一蓝色子像素单元B3与第二蓝色子像素单元B4与子像素2’排布方向的垂直方向进行排布作为示例进行说明。第一蓝色子像素单元B3与第二蓝色子像素单元B4可以如图6所示与子像素2’排布方向的平行方向进行排布，本申请对此不做限制。第一绿色子像素单元G3、第二绿色子像素单元G4、第一红色子像素单元R3和第二红色子像素单元R4的排布同理，在此不再赘述。
请继续参阅图7。在子像素组2中，同色子像素2’的第一子像素单元21与第二子像素单元22呈轴对称排布。
采用图7所示的子像素2’排布方式，第一子像素单元21排列在一行，第二子像素单元22的排列在一行。这种排布方式能够方便第一发光功能层221和第二发光功能层222的制作。在图案化第一阳极层211、第二阳极层212、第一阴极层231以及第二阴极层232时，也能节约光刻成本。
请参阅图8，图8是本申请提供的双面显示面板的第五种像素排布示意图。在相邻两个子像素组2中，同色子像素2’的第一子像素单元21与第二子像素单元22呈中心对称排布。
采用图8所示的子像素2’排布方式，第一子像素单元21和第二子像素单元22在相邻子像素组2中交错排列，能够更好的实现第一发光功能层221和第二发光功能层222的混光。从而使显示面出射的光线更平均，实现更好的显示效果。
请参阅图9，图9是本申请提供的双面显示面板的第六种像素排布示意图。子像素2’包括第一类子像素2A与第二类子像素2B。第一类子像素2A中同色的第一子像素单元21和第二子像素单元22在相邻子像素组2中呈轴对称排布。第二类子像素2B中同色的第一子像素单元21和第二子像素单元22在相邻子像素组2中呈中心对称排布。
在图9中，以红色子像素为第一类子像素2A、绿色子像素为第二类子像素2B为例进行说明。红色子像素包括第一红色子像素单元R3和第二红色子像素单元R4。绿色子像素包括第一绿色子像素单元G3和第二绿色子像素单元G4。在相邻两个子像素组2中，第一红色子像素单元R3和第二红色子像素单元R4均呈轴对称排布。在相邻两个子像素组2中，第一红色子像素单元R3和第二红色子像素单元R4呈轴对称排布。在相邻两个子像素组2中，第一绿色子像素单元G3和第二绿色子像素单元G4呈轴对称排布。
在图9所示的像素排布中，第一子像素单元21和第二子像素单元22以相邻两个子像素组2为单位进行排布。这样能够使第一子像素单元21和第二子像素单元22在子像素组2中得到复用，在两个显示面均实现更好的混光效果。
本申请提供的双面显示面板10适应多种不同的像素排列方式。在不同的像素排列方式中，子像素2’的第一像素结构10a、第二像素结构10b也可以采用不同的排列方式。本申请提供的双面显示面板10可以适应不同的显示需求。需要说明的是，本申请以上像素排列方式仅为示意。将子像素2’拆分为第一子像素单元21和第二子像素单元22即可解决本申请的技术问题。本申请对像素排列方式不做限制。
本申请提供一种双面显示装置。请参阅图10，图10是本申请提供的双面显示装置的一种结构示意图。双面显示装置100包括一种双面显示面板10，双面显示面板10为以上所述的双面显示面板10，自此不再赘述。双面显示装置100还包括封装结构20，封装结构20设置在双面显示面板10上。
其中，封装结构20包括一无机层、一有机层或交替层叠设置的至少一无机层和至少一有机层。无机层可以选自氧化铝、氧化硅、氮化硅、氮氧化硅、碳化硅、氧化钛、氧化锆和氧化锌中的一种或多种的组合。有机层选自环氧树脂、聚酰亚胺、聚对苯二甲酸乙二醇酯、聚碳酸酯（Polycarbonate, PC）、聚乙烯和聚丙烯酸酯（Polyacrylate）中的一种或多种的组合。
本申请提供的双面显示装置100包括一种双面显示面板10。双面显示面板10将相邻子像素组中的同色子像素分别对应设置为第一像素结构和第二像素结构。或者，将子像素拆分为第一子像素单元和第二子像素单元，并使第一子像素单元和第二子像素单元分别对应设置为第一像素结构和第二像素结构。则双面显示面板10在一显示面发出的光线为两种像素结构出射光线的平均，从而使得在一个局部区域内，同色子像素朝同一侧发光的亮度、色度、视角等均是统一的，进而保证了双面显示面板10两侧的显示效果是统一的。
本申请提供的双面显示装置100可应用于电子设备中。电子设备为智能手机（smartphone）、平板电脑（tablet personal computer）、移动电话（mobile phone）、视频电话机、电子书阅读器（e-book reader）、台式计算机（desktop PC）、手提电脑（laptop PC）、上网本（netbook computer）、工作站（workstation)、服务器、个人数字助理（personal digital assistant）、便携式媒体播放器（portable multimedia player）、MP3播放器、移动医疗机器、照相机、游戏机、数码相机、车载导航仪、电子广告牌、自动取款机或可穿戴设备（wearable device）中的任一种。
以上对本申请所提供的双面显示面板及双面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。
