在本实施例中，所述黑色遮挡层600与所述黑色挡墙310共同形成遮光结构。可以理解的是，这种遮光结构，通过在所述黑色遮挡层600来吸收所述显示面板的所述台阶子区3000的漏光，结构简单，且实现工艺简单，仅需要在第一基板100和第二基板200对盒后，在所述第一偏光片410的延伸段一侧形成黑色遮挡层600，然后在所述显示面板的出光侧粘附所述第一偏光片410即可，可降低制作工艺的复杂性，降低成本；当然，所述填充层700可在所述显示面板的出光侧粘附所述第一偏光片410前进行制备，或者在所述显示面板的出光侧粘附所述第一偏光片410后进行制备，本实施例对此不做具体限制。
请参阅图5，本申请实施例所提供的显示模组的第二种结构示意图。
在本实施例中，所述显示面板的结构与上述实施例所提供的显示面板的第一种结构相似/相同，具体请参照上述实施例中的显示面板的描述，此处不再赘述，两者的区别仅在于：
在本实施例中，所述黑色遮挡层600包括向所述显示区1000延伸且位于所述黑色挡墙310上方的黑色遮挡子层610，所述黑色挡墙310在所述第二基板200上的正投影覆盖所述黑色遮挡子层610在所述第二基板200上的正投影。
在本实施例中，所述黑色遮挡子层610至少覆盖所述黑色挡墙310和所述填充层700的间隙处，且所述黑色遮挡子层610未覆盖所述显示面板的所述显示区1000。可以理解的是，所述黑色遮挡子层610与所述黑色遮挡层600的材料可以相同，且所述黑色子遮挡层与所述黑色遮挡层600均位于所述第一偏光片410的同一侧，因此所述黑色子遮挡层与所述黑色遮挡层600可以同时制备，从而减少所述显示面板的制备过程。
本实施例通过在所述黑色遮挡层600向所述显示区1000延伸且位于所述黑色挡墙310上方设置黑色遮挡子层610，所述黑色遮挡子层610至少覆盖所述黑色挡墙310和所述填充层700的间隙处，从而进一步防止所述黑色挡墙310与所述填充层700之间的缝隙造成漏光，且所述黑色遮挡子层610未覆盖所述显示面板的所述显示区1000，以避免对所述显示面板的所述显示区1000域造成干涉。
请参阅图6，本申请实施例所提供的显示模组的第三种结构示意图。
在本实施例中，所述显示面板的结构与上述实施例所提供的显示面板的第二种结构相似/相同，具体请参照上述实施例中的显示面板的描述，此处不再赘述，两者的区别仅在于：
在本实施例中，所述显示模组还包括绑定于所述绑定段101上的覆晶薄膜800；其中，所述黑色遮挡层600在垂直于所述显示面板方向上的正投影覆盖所述覆晶薄膜800和所述绑定段101在垂直于所述显示面板方向上的正投影。
具体地，所述显示模组采用COF结构，所述显示模组还包括覆晶薄膜800（Chip On Flex, or, Chip On Film,常称COF），所述覆晶薄膜800绑定于所述绑定段101上，所述覆晶薄膜800上设置有驱动电路900；所述黑色遮挡层600在垂直于所述显示面板方向上的正投影覆盖所述覆晶薄膜800、所述绑定段101以及所述驱动电路900在垂直于所述显示面板方向上的正投影。

需要说明的是，所述第一基板100可以为阵列基板和彩膜基板中的一者，所述第二基板200可以为阵列基板和彩膜基板中的另一者，本实施例对此不做具体限制。
在本实施例中，所述显示面板还包括设置于述第一基板100和所述第二基板200之间的黑色矩阵300，所述黑色矩阵300位于所述非显示区2000，其中，所述黑色矩阵300包括靠近所述台阶子区3000的黑色挡墙310。
步骤S20：提供一第一偏光片410，所述第一偏光片410包括一延伸段，在所述延伸段一侧形成黑色遮挡层600。
请结合图8，在所述步骤S20中，包括以下步骤：
步骤S21：提供偏光膜片400，所述偏光膜片400包括第一偏光片410和形成于所述第一偏光片410上的离型膜430，所述第一偏光片410包括一延伸段。
具体地，所述偏光膜片400还包括位于所述第一偏光片410远离所述离型膜430一侧的保护膜440。
步骤S22：裁切所述离型膜430形成与所述延伸段相对应的离型子膜431。
步骤S23：去除所述离型子膜431，在所述延伸段上形成所述黑色遮挡层600。
具体的，所述步骤S23包括但不限于利用卷取装置去除所述离型子膜431，并同时在所述延伸段上形成所述黑色遮挡层600，或者利用裁切机器完全去掉所述离型子膜431，然后在所述延伸段上形成所述黑色遮挡层600，可以理解的是，本实施例对此不做具体限制。
步骤S30：在所述显示面板的出光侧粘附所述第一偏光片410，所述第一偏光片410设置于所述第二基板200远离所述第一基板100一侧，其中，所述黑色遮挡层600在所述第一基板100上的正投影至少覆盖所述绑定段101。
具体地，在本实施例中，所述黑色遮挡层600在所述第一基板100上的正投影与所述黑色挡墙310在所述第一基板100上的正投影相邻，且间距等于0。
在本实施例中，所述黑色遮挡层600与所述黑色挡墙310共同形成遮光结构。可以理解的是，这种遮光结构，通过在所述黑色遮挡层600来吸收所述显示面板的所述台阶子区3000的漏光，结构简单，且实现工艺简单，仅需要在所述第一偏光片410的延伸段一侧形成黑色遮挡层600，然后在所述显示面板的出光侧粘附所述第一偏光片410即可，可降低制作工艺的复杂性，降低成本。
进一步地，在本实施例中，所述显示模组的制作方法还包括以下步骤：
步骤S40：提供一第二偏光片420。
步骤S50：在所述显示面板远离所述出光侧粘附所述第二偏光片420，所述第二偏光片420设置于所述第一基板100远离所述第二基板200一侧，且所述第二偏光片420在所述第一基板100上的投影位于所述第一基板100内。
步骤S60：在所述黑色遮挡层600与所述绑定段101之间形成填充层700；其中，所述黑色遮挡层600在垂直于所述显示面板方向上的正投影至少覆盖所述填充层700在垂直于所述显示面板方向上的正投影。
具体的，所述填充层700靠近所述第二基板200一侧的侧边与所述黑色遮挡层600靠近所述第二基板200一侧的侧边平齐，所述填充层700远离所述第二基板200一侧的侧边与所述黑色遮挡层600远离所述第二基板200一侧的侧边平齐，从而使所述填充层700对所述第一偏光片410起到支撑作用，防止所述第一偏光片410在所述台阶子区3000形成凹陷，即，在所述台阶子区3000设置所述填充层700，使所述第一偏光片410为一平整面，从而可以保证所述显示面板的平坦，确保四边无边框显示模组的整体平面的设计感。
需要说明的是，所述填充层700的材料包括但不限于光学胶，并且，在所述显示面板的台阶子区3000，所述第一偏光片410的边缘不仅超出第二基板200的边缘，还超出第一基板100的衬底基板边缘，且超出所述第一基板100的衬底基板的长度大约为1～3mm，这样，可以保证在第一偏光片410与第一基板100的衬底基板之间更容易制备所述填充层700。
可以理解的是，所述填充层700还可在所述步骤S30之前进行制备，即，在所述显示面板的出光侧粘附所述第一偏光片410之前，在所述台阶子区3000内，在所述第一基板100位于所述台阶子区3000内的绑定段101上形成所述填充层700，所述填充层700靠近所述第二基板200一侧的侧边与所述第二基板200的边缘齐平。
步骤S70：在所述绑定段101上绑定覆晶薄膜800；其中，所述黑色遮挡层600在垂直于所述显示面板方向上的正投影覆盖所述覆晶薄膜800和所述绑定段101在垂直于所述显示面板方向上的正投影。
本实施例还提供一种显示装置，包括上述实施例中任一所述显示模组。
其中，所述显示模组已经在上述实施例中进行了详细的说明，在此不在重复说明。
在具体应用时，所述显示装置可以为智能手机、平板电脑、笔记本电脑、智能手环、智能手表、智能眼镜、智能头盔、台式机电脑、智能电视或者数码相机等等设备的显示屏，甚至可以应用在具有柔性显示屏的电子设备上。
