目前，随着全屏幕显示的市场发展需求，将摄像头集成设置于显示面板的下方，成为当前显示装置结构设计的主要方向。
对于集成于显示面板下方的摄像头，为实现拍摄功能，要求显示面板对应摄像头的区域设置为能够透光的显示区域，目前用户对屏下摄像头中摄像头对应透光显示区域的透光要求日益提高，为呈现更好的前置拍摄效果，通常需要增加前置摄像头的尺寸，这就要求对应透光显示区域的尺寸也需要相应增大。
然而，由于透光显示区域还需要满足显示功能，基于透光显示区域内用于图像显示的像素单元的布置要求，受驱动信号走线的空间限制，透光显示区可驱动的像素个数受到限制，从而制约了透光显示区的尺寸，导致前置摄像头的尺寸也就受到影响。

本公开实施例中，可选地，如图1所示，透光区100形成为显示面板的 显示区3的其中一部分区域。可选地，显示面板为OLED显示面板，发光器件单元111为OLED像素单元中的OLED发光单元，发光驱动单元121为OLED像素单元中用于驱动OLED发光单元发光的驱动单元。
其中，发光器件单元111和发光驱动单元121制作于透明衬底上，在第一透光区110，可选地，发光器件单元111采用透光材料制作，也即形成为能够透光的结构，从而形成第一透光区110的透光效果；可选地，发光器件单元111不限于仅能够采用透光材料制作，也可以利用间隔分布的发光器件单元111之间间隙的透光功能，形成第一透光区110的透光效果。
在第二透光区120，多个发光驱动单元121采用透光材料制作，形成为能够透光的结构，从而形成第二透光区120的透光效果。
本公开实施例中，可选地，如图1所示，显示面板还包括显示区3，显示区3内设置有多个阵列排列的像素单元，可选地，显示区3围绕透光区100设置，或者透光区100设置于显示区3的其中一边缘。可选地，显示区3内设置的像素单元可以采用透光材料制作，也可以不采用透光材料制作，在此不作限定。
采用该实施结构所述显示面板，在透光区100远离显示面板的一侧，可以设置摄像头，利用透光区100的第一透光区110和/或第二透光区120的透光功能，入射至显示面板的光线能够传输至摄像头，用于图像拍摄。
本公开实施例中，透光区100利用发光驱动单元121驱动发光器件单元111发光，能够实现透光区100的显示功能。因此，显示面板的整个显示区3均能够用于图像显示，不会由于透光区100的设置影响显示效果。

采用该实施方式，在透光区100内，第一透光区110的发光器件单元111的阳极可以复用为第一连接线1，延伸至第二透光区120，与发光驱动单元121的驱动电极1211连接。由于不需要单独设置连接线，相较于上述实施第一连接线的实施方式，可以达到增加可控像素结构数量的效果。
由于发光器件单元111的阳极通常为不透光结构，本公开实施例中，可选地，第一连接线1可以采用部分采用透明的ITO材料制作，另一部分采用发光器件单元111的阳极复用的方式。
需要说明的是，上述透光区内发光器件单元和发光驱动单元的实施结构，以及透光区内第一连接线和第二连接线的设置结构仅为举例说明，具体并不以此为限，例如，第一连接线和/或第二连接线可以设置为多层结构，在此不再详细举例说明。
本公开实施例所述显示面板，能够增加摄像头透光显示区发光器件的控制数量，增大透光显示区尺寸；对于前置摄像头尺寸较小的产品，可以提高透光显示区的像素密度，提高显示质量。

可选地，所述的显示装置，还包括摄像头模组，所述摄像头模组在所述显示面板所在平面的正投影，位于所述第一透光区内。
具体地，摄像头模组形成为显示装置的前置摄像头，并构成为屏下摄像头结构。
根据以上所述显示面板的详细描述，本领域技术人员应该了解采用本公开实施例所述显示面板的显示装置的具体结构，在此不再详细说明。

结合图4和图5，并参阅以上的详细描述，本领域技术人员应该能够了解本公开实施例所述显示面板的具体制备过程，在此不再详细说明。
除非另外定义，本公开使用的技术术语或者科学术语应当为本公开所属领域内具有一般技能的人士所理解的通常意义。本公开中使用的“第一”、“第二”以及类似的词语并不表示任何顺序、数量或者重要性，而只是用来区分不同的组成部分。“包括”或者“包含”等类似的词语意指出现该词前面的元件或者物件涵盖出现在该词后面列举的元件或者物件及其等同，而不排除其他元件或者物件。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”等仅用于表示相对位置关系，当被描述对象的绝对位置改变后，则该相 对位置关系也可能相应地改变。
可以理解，当诸如层、膜、区域或基板之类的元件被称作位于另一元件“上”或“下”时，该元件可以“直接”位于另一元件“上”或“下”，或者可以存在中间元件。
在上述实施方式的描述中，具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
