 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他实施例，都属于本申请保护的范围。
请参阅图1，图1为本申请提供的显示面板的第一种实施方式的结构示意图。本申请提供一种显示面板1，包括基板10、发光单元20、四分之一波片30以及线偏光层40。
基板10可以是玻璃基板或者其他材质的基板。多个发光单元20设置在基板10上，且多个发光单元20可以是呈阵列式排布，用于实现画面显示。其中，薄膜晶体管阵列的薄膜晶体管的漏极可以和发光像素单元20的阳极层201电连接，以实现薄膜晶体管和发光单元20的连接。其中，每个发光单元20对应一个阳极层201和一个有机发光层202，所有发光单元20可以共用一层阴极层203、一层空穴注入层204、一层空穴传输层205以及一层电子传输层206，即所有发光像素单元20的阴极层203连接为一整片式的阴极层203，所有发光单元20的空穴注入层204连接为一整片式的空穴注入层204，所有发光单元20的空穴传输层205连接为一整片式的空穴传输层205，所有发光单元20的电子传输层206连接为一整片式的电子传输层206。当然，各发光单元20的阴极层也可以是单独存在，各发光像素单元20的空穴注入层也可以是单独存在，以此类推空穴传输层和电子传输层的结构。
四分之一波片30设置在基板10上且覆盖多个发光单元20，线偏光层40设置在四分之一波片30上。其中，该线偏光层40可以包括多个线偏光块401，每一线偏光块401对应设置在相邻发光单元20之间。四分之一波片30和多个线偏光块401共同构成了圆偏光片结构。
在一种实施方式中，请继续参阅图1。多个发光单元20间隔排布。其中，每一线偏光块401对应设置在发光单元20的间隔处。需要说明的是，每个线偏光块401对应设置在发光单元20的间隔处指的是：每个线偏光块401在基板10上的正投影位于相邻发光单元20在基板上的正投影之间，如图1所示。
比如，当显示面板1工作时，发光单元20射出的垂直于发光单元20的线偏振光通过四分之一波片30后，转变成圆偏振光。因此，提高该显示面板1的发光亮度。另外，多个线偏光块401是设置在对应于相邻两个发光单元20之间的间隔处，多个线偏光块401和四分之一波片30的叠加可起到圆偏光片的作用，从而能够阻隔外界光的反射，有利于降低显示面板1的暗态反射率，提高显示面板1的对比度。
请参阅图2，图2为本申请提供的显示面板的第二种实施方式的结构示意图。本申请提供一种显示面板1。图2的显示面板1与图1的显示面板1的区别在于：显示面板1还包括第一配向层402。
该第一配向层402设置在四分之一波片30上，且多个线偏光块401间隔设置在第一配向层402上。
其中，在一种实施方式中，线偏光块401的材料为向列相液晶。该第一配向层402的材料可以是聚酰胺材料（Polyamide，PA）。该第一配向层402用于对线偏光块401配向，使得线偏光块401中的液晶按一定的方向整齐排列。该第一配向层402与多个线偏光块401共同构成了线偏光层40，该线偏光层40可以起到光学调制作用。
另外，四分之一波片30也可以是类似线偏光层40的结构。请参阅图3，图3为本申请提供的显示面板的第三种实施方式的结构示意图。本申请提供一种显示面板1。图3的显示面板1与图1的显示面板1的区别在于：四分之一波片30包括第二配向层301和液晶层302。其中，该第二配向层301设置在基板10上，且第二配向层301覆盖多个发光单元20，液晶层302设置在该第二配向层301上。
需要说明的是，由于图3中的四分之一波片30采用的是类似图2中线偏光层40的结构。因此，决定其是线偏光层40还是四分之一波片层30的因素有两个：（1）掺杂的液晶的比例；（2）配向工艺。掺杂的液晶的比例和配向工艺具体根据实际情况而定。
此外，还需要说明的是，现有的偏光片的结构多层结构，该多层结构至少包括保护膜、离型膜、压敏胶、聚乙烯醇以及两层三醋酸纤维素保护膜。相较于现有技术而言，本申请的圆偏光片可以为4层结构，即，多个线偏光块401、第一配向层402、第二配向层301以及液晶层302。因此，该圆偏光片不仅可以阻隔外界光的反射，有利于降低显示面板1的暗态反射率，提高显示面板1的对比度。并且，还有利于减小显示面板1的厚度。
在一种实施方式中，显示面板1还可以包括封装层50。请参阅图4，图4为本申请提供的显示面板的第四种实施方式的结构示意图。本申请还提供一种显示面板1。图4的显示面板1与图1的显示面板1的区别在于：显示面板1还包括封装层50。其中，该封装层50设置在线偏光层40上，且该封装层50覆盖多个线偏光块401。
通过设置封装层50，在提高显示面板1的对比度的同时，还避免该线偏光层40中线偏光块401出现损伤的情况。
另外，在另一种实施方式中，封装层50还可以设置在别的位置。请参阅图5，图5为本申请提供的显示面板的第五种实施方式的结构示意图。本申请还提供一种显示面板1。图5的显示面板1与图4的显示面板1的区别在于：封装层50设置在发光单元20与四分之一波片30之间。
将封装层50设置在发光单元20与四分之一波片30之间，可以保护四分之一波片30下方的膜层，如阴极层203。并且，为四分之一波片30与显示面板1之间的结合提供便利性。同时，四分之一波片30设置在封装层50上，当四分之波片30出现贴附不均的问题时，不会损伤显示面板1的发光元件。
此外，在线偏光层40上还可以设置透明光学胶层60，如图6所示。一方面，该透明光学胶层60可以保护线偏光层40。另一方面，该透明光学胶层60可以实现与盖板或者其他膜层的黏贴。
请参阅图7，图7为本申请提供的显示面板的第七种实施方式的结构示意图。本申请还提供一种显示面板1。图7的显示面板1与图1的显示面板1的区别在于：显示面板1还包括粘结层70。其中，该粘结层70设置在发光单元20与四分之一波片30之间。该粘接层70的材料可以为压敏胶，用于将四分之一波片30粘接在发光单元20上。
本申请将偏光块401设置在相邻发光单元20之间，当显示面板1发光时，发光单元20垂直射出的光线通过四分之一波片30后射出，不会经过线偏光块401。因此，减少了显示面板1发出的光线损耗，大大提高了显示面板1的发光亮度。
请参阅图8，图8为本申请提供的显示面板的制备方法的流程示意图。本申请提供一种显示面板的制备方法，该方法包括：
110、提供一发光基板。
其中，该发光基板包括基板以及设置在所述基板上的发光单元。基板10可以是玻璃基板或者其他材质的基板。多个发光单元20设置在基板10上，且多个发光单元20可以是呈阵列式排布，用于实现画面显示。其中，薄膜晶体管阵列的薄膜晶体管的漏极可以和发光像素单元20的阳极层201电连接，以实现薄膜晶体管和发光单元20的连接。其中，每个发光单元20对应一个阳极层201和一个有机发光层202，所有发光单元20可以共用一层阴极层203、一层空穴注入层204、一层空穴传输层205以及一层电子传输层206，即所有发光像素单元20的阴极层203连接为一整片式的阴极层203，所有发光单元20的空穴注入层204连接为一整片式的空穴注入层204，所有发光单元20的空穴传输层205连接为一整片式的空穴传输层205，所有发光单元20的电子传输层206连接为一整片式的电子传输层206。当然，各发光单元20的阴极层也可以是单独存在，各发光像素单元20的空穴注入层也可以是单独存在，以此类推空穴传输层和电子传输层的结构。如图1至图7所示。
120、在发光基板上形成四分之一波片。
比如，可以将预先制成的四分之一波片贴附在发光基板上。或者，在发光基板上涂敷一层配向层。然后，在该配向层上涂敷一层液晶，以形成图3、图4、图5、图6或图7中四分之一波片30的结构。具体结构请参阅前面实施例，在此不再赘述。
130、在四分之一波片上形成具有图案化的线偏光层。
其中，线偏光层包括多个线偏光块，每一线偏光块对应设置在相邻发光单元之间。
在一种实施方式中，“在四分之一波片上形成具有图案化的线偏光层”的步骤可以包括：
将掩膜板放置在四分之一波片上。
在掩膜板上涂覆液晶。
固化液晶，并去除掩膜板，以在四分之一波片上形成具有图案化的线偏光层。
在该实施方式中，掩膜板包括遮挡区域和涂覆区域。首先，将掩膜板放置在四分之一波片上。然后，在四分之一波片上涂敷一层液晶。由于掩膜板包括遮挡区域和涂覆区域。因此，遮挡区域对应在四分之一波片上的位置不会有液晶的存在。紧接着，可以采用光照对液晶进行固化。液晶根据涂敷区域的形状形成多个液晶块。最后，去除该掩膜板。此时，四分之一波片上已经形成具有图案化的线偏光层。具体结构请参阅前面实施例，在此不再赘述。
在另一种实施方式中，“在四分之一波片上形成具有图案化的线偏光层”的步骤可以包括：
将液晶注入模具中；
对模具进行光照处理，得到多个线偏光块；
将多个偏光块贴合至四分之一波片上，以在四分之一波片上形成具有图案化的线偏光层。
首先，将液晶注入进预先制成的模具中。该模具上设置有多个凹槽。线偏光块的尺寸根据该凹槽的尺寸而定。然后，对模具进行光照处理，使得液晶在模具中固化，从而得到多个线偏光块。最后，再将这多个线偏光块贴合至四分之一波片上，以在四分之一波片上形成具有图案化的线偏光层。具体结构请参阅前面实施例，在此不再赘述。
