 附图说明
为了更清楚地说明本申请实施例中的技术方案，下面将对本申请实施例中所需要使用的附图进行说明。
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；
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；
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；
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。
 本发明的实施方式
下面详细描述本申请的实施方式，所述实施方式的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施方式是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。
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、像素定义层20以及发光单元30。其中，像素定义层20设置在基板10上。并且，该像素定义层20包括多个间隔排布的像素块21，发光单元30设置在相邻像素定义块21之间，且该发光单元两侧均设置有遮光部40。
该基板10为柔性基板或者刚性基板，并且，该基板10根据实际需求可以包括各种电路结构和/或基板结构。比如，该基板10可以包括基底11以及薄膜晶体管12。该薄膜晶体管12设置在基底11上，且发光单元与该薄膜晶体管的漏极121相连接。
多个像素块21间隔设置在该基板10上。该多个像素定义块21可以通过喷墨打印工艺预先在基板10上制作像素定义层20。然后以限定墨滴并且精确的喷入制定的区域形成像素定义块21。形成像素定义块21的材料为疏液性材料，且该像素定义块21的纵向截面形状可以为梯形。当该像素定义块21的纵向截面形状为梯形时，可以提高该显示面板1的开口率，从而提高显示效果。当然，该像素定义块21的纵向截面形状也可以为矩形，具体根据实际需求进行设置。
此外，发光单元30设置在相邻像素定义块21之间。其中，发光单元30的两侧均设置有遮光部40。该遮光部40的材料可以为黑色树脂材料。当显示面板1工作时，由于在发光单元30的两侧分别设置遮光部40，发光单元30发出的光线不会从发光单元30的两侧射出。因此可以提高该显示面板1的对比度，从而提高了显示面板1的显示效果。
请继续参阅图1，如图1所示，像素定义块21包括相对设置的第一端部211、第二端部212，以及设置在第一端部211与第二端部212之间的侧部213.遮光部40沿着侧部213设置。发光单元30可以包括依次层叠设置的阳极31、发光层32以及阴极33。其中，遮光部40设置在阳极31上，且遮光部40设置在侧部213与发光层32之间。
需要说明的是，该遮光部40围绕发光层32以及阴极33设置。比如，该遮光部40沿着侧部213设置，且设置在侧部213和发光层32之间。其中，该遮光部40远离阳极31的一端到阳极31的距离D大于阴极33到阳极31的距离L，如图1所示。当显示面板1工作时，发光单元30发出的光线不会从发光单元30的侧部射出。因此，可以避免显示面板1的对比度下降问题，从而提高了显示面板1的显示效果。
在一些实施方式中，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。本申请还提供一种显示面板1。图2的显示面板1与图1的显示面板1的区别在于：遮光部40远离阳极31的一端到阳极31的距离D等于阴极33到阳极31的距离L。即，遮光部40远离阳极31的一端与阴极33的表面平齐。
当显示面板1工作时，由于在发光单元30的两侧均设置有遮光部40，所以发光单元30发出的光线不会从发光单元30的侧部射出。因此，可以避免显示面板1的对比度下降问题，从而提高了显示面板1的显示效果。
另外，由于遮光部40远离阳极31的一端到阳极31的距离D等于阴极33到阳极31的距离L，在制作遮光部40的过程中，可以减少该遮光部40的用料。因此，达到降低生产成本的目的。
在另一种实施方式中，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。本申请还提供一种显示面板1。图3的显示面板1与图1的显示面板1的区别在于：遮光部40可以设置在阳极31和阴极33之间。
比如，遮光部40可以设置在阳极31和阴极33之间，且遮光部40、阳极31以及阴极33包围发光层32设置。由于阳极31和阴极33之间的相互作用导致发光层32发光。因此，将遮光部40设置在阳极31和阴极33之间，也可以使得发光单元30发出的光线不会从发光单元30的侧部射出。避免了显示面板1的对比度下降的问题，进而提高了显示面板1的显示效果。另外，还可以减少遮光部40的用料，达到降低生产成本的目的。
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：
像素定义块21的侧部213朝向发光单元30的一侧设置有多个凹槽2131，且多个凹槽2131连续设置，遮光部40填充设置在凹槽2131内。其中，遮光部40包括多个遮光块41，遮光块41设置在凹槽2131内。并且，遮光块41与凹槽2131相适应，以使得侧部213朝向发光单元30的一侧表面平整。
首先，可以在像素定义块21的侧部213设置多个凹槽2131。然后在凹槽2131的内部设置遮光块41。由于多个凹槽2131是连续设置的。因此，多个遮光块41靠近发光单元30的一侧，会形成有一层遮光薄膜。这样不仅可以避免显示面板1的对比度下降的问题。同时，还可以提高遮光部40与像素定义块21之间的粘合性，从而提高显示面板1的产品良率。
另外，由于像素定义块21的侧部上设置有多个凹槽2131。在制作遮光部40时，只需沿着凹槽2131涂布遮光材料，以在凹槽2131内形成遮光块41。这样不仅制作遮光部40的工艺简便，还可以避免遮光部40过厚造成发光区域过小的问题。
需要说明的是，每个遮光块41均对应一个凹槽2131，且每个遮光块41的纵向截面形状与该遮光块41对应对应的凹槽的凹陷区域形状一致。比如，遮光块41的纵向截面形状为长方形，且该长方形的长为6微米，长方形的宽为3微米。该遮光块41对应的凹槽的凹陷区也应为长方形，且凹陷区的长为6微米，凹陷区的宽为3微米。此外，凹槽2131的个数根据实际情况设置。图中仅仅只是示意，并非作为对本申请的限制。
相应的，本申请还提供了一种显示装置。该显示装置包括显示面板1，其中，该显示面板1请参阅前面实施例，在此不再赘述。
以上对本申请实施例提供的显示面板以及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。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。
