本发明针对现有的采用屏下摄像头的OLED显示面板中，摄像头区域不显示画面，无法呈现全屏显示的效果，影响用户体验的技术问题。
一种显示装置，如图1所示，所述显示装置包括显示面板10，所述显示面板10包括主显示区11和功能附加区12，所述功能附加区12的至少一部分被所述主显示区11围绕。

功能附加区12既可以用于显示图像，从而使得显示面板10可以呈现全屏显示的效果，又可以用于安装摄像头、光学触控组件以及指纹识别传感器等感光元件，提高用户体验。
需要说明的是，功能附加区12中的像素密度可以与主显示区11中的像素密度相同，也可以不同；功能附加区12处的显示亮度可以与主显示区11处的显示亮度相同，也可以不同。

其中，所述功能附加区12中设有至少一个透光区121，所述透光区121中排布有多个第一像素122。
通过在所述功能附加区12中设置至少一个透光区121，利用透光区121提高功能附加区12的整体透光率，保证功能附加区12的整体透光率，从而可以在功能附加区12同时实现良好的显示和摄像功能，提升用户体验。
如图2所示，所述显示面板10包括基板50、设置在所述基板50上且位于所述透光区121的外围的多个第一驱动电路1221、设置于所述基板50上的至少两层绝缘层，所述第一驱动电路1221被所述绝缘层覆盖，所述第一驱动电路1221与所述第一阳极20通过位于至少两层所述绝缘层中的透明导线电性连接。
进一步的，所述透明导线包括至少两层位于不同层别的连接走线。
进一步的，所述基板50上设置有位于所述主显示区11中的第二驱动电路1112，所述第二像素111通过设于至少两层所述绝缘层中的导电层与所述第二驱动电路1112电性连接。
在一实施方式中，所述显示面板10包括设置于所述基板50上的第一驱动电路1221、覆盖所述第一驱动电路1221的第一绝缘层61、设置于所述第一绝缘层61上的第一搭接走线71、覆盖所述第一搭接走线71的第二绝缘层62、设置于所述第二绝缘层62上的第二搭接走线72、覆盖所述第二搭接走线72的第三绝缘层63、设置于所述第三绝缘层63上的第三搭接走线73、覆盖所述第二搭接走线72的第四绝缘层64、设置于所述第四绝缘层64上的像素阳极以及像素定义层80，所述像素定义层80上具有对应于像素阳极的像素开口81。
位于所述透光区121的搭接走线为透明导线；位于不同层别的搭接走线通过过孔电性连接，通过位于不同层别的所述搭接走线的电性连接，实现第一阳极20与第一驱动电路1221的电性连接，从而便于布线排布。
具体的，位于同一层别的相邻两条搭接走线之间的间距大于2微米，以避免位于同一层别的相邻两条搭接走线之间发生短路；每条搭接走线的线宽大于1微米。
其中，所述像素阳极包括第一阳极20和用于驱动第二像素111的第二阳极1111，所述第二阳极1111位于所述主显示区11，所述导电层可以与所述透明导线的结构和制程相同，所述第二阳极1111通过多层搭接走线与第二驱动电路1112电性连接。
需要说明的是，实际实施中，导电层也可以为位于主显示区11中的多层不透明的导电走线形成，即位于主显示区11中的搭接走线为不透明的导电走线。
需要说明的是，图2中仅示意了第一阳极20通过位于透光区121的搭接走线与第一驱动电路1221电性连接的情况，实际实施中，第一阳极20还可以通过位于功能附加区12中其他区域处的搭接走线或主显示区11中的搭接走线与所述第一驱动电路1221电性连接。
需要说明的是，图2中仅示意了具有三层搭接走线的情况，实际实施中，还可以设置成两层、四层、五层或更多层搭接走线。
需要说明的是，所述透明导线的制备材料包括但不限于铟锡金属氧化物、铟锌金属氧化物、氟锡金属氧化物或纳米银线；绝缘层由透明材料制备，绝缘层包括但不限于氧化硅或氮化硅。
具体的，如图3所示，每个所述透光区121的面积均大于或等于0.32平方毫米。
可以理解的是，透光区121的设置可以增加功能附加区12的光透光率，而第一像素122的驱动需要与之电性连接的透明导线，透光区121的面积越大，可以减小用于驱动第一像素122的透明导线对光的干涉和衍射，从而提升摄像头等感光元件的使用效果。
如图3所示，每个所述透光区121的面积均小于或等于120平方毫米。
进一步的，每个所述透光区121的面积均为0.36～100平方毫米。
需要说明的是，对于本领域技术人员可知，透光区121的面积越大，需要设置的搭接走线的层数越多，制程上难度就会越大，成本越高，因此对透光区121的面积范围进行合理的设置，可以在保证透光区121显示和透光功能的情况下，降低制程难度。
在一实施方式中，每个所述透光区121的面积可以为0.5平方毫米、2平方毫米、10平方毫米、20平方毫米、50平方毫米或80平方毫米，在此不一一列举。
需要说明的是，所述透光区121设置有一个时，可以根据功能附加区12的实际面积将透光区121的面积设置的尽可能大，如透光区121的面积可以为120平方毫米；所述透光区121设置有两个或两个以上时，可以根据功能附加区12的实际面积将透光区121的面积设置的尽可能大，并且可以理解的是，透光区121的个数越多，每个透光区121的面积越小。
具体的，每个所述透光区121的面积大于或等于每个所述第二像素111的面积的50倍。
进一步的，每个所述透光区121的面积小于或等于每个所述第二像素111的面积的210000倍。
更进一步的，每个所述透光区121的面积为每个所述第二像素111的面积的70～200000倍。
在一实施方式中，每个所述透光区121的面积可以为每个所述第二像素111的面积的100倍、500倍、1000倍、5000倍、10000倍或50000倍，在此不一一列举。
至少一个所述透光区121中设置有用于驱动所述第一像素122的第一阳极1222。
具体的，位于所述透光区121中的所有所述第一阳极20的面积之和小于或等于对应的透光区121的面积的50%。
进一步的，位于所述透光区121中的所有所述第一阳极20的面积之和大于或等于对应的透光区121的面积的5%。
需要说明的是，参见图8可知，第一阳极20的部分可能会被像素定义层80遮挡，在一实施方式中，位于所述透光区121中的所有所述第一阳极20未被所述像素定义层80遮挡的部分的面积之和小于或等于对应的透光区121的面积的50%。
需要说明的是，对于本领域技术人员可知，第一阳极20的制备材料一般包括不透明材料，如层叠设置的第一透明导电膜层、银膜层和第二透明导电膜层，通过对第一阳极20的所占透光区121的面积进行限制，保证第一像素122的密度的同时，防止第一阳极20影响透光区121的显示。
需要说明的是，在限定透光区121的面积时，参见图3至图9，通过对透光区121的整体形状进行设计，也可以提高功能附加区12的整体透光性。
在一实施方式中，所述透光区121的整体形状呈圆形（如图3）、大半圆形（如图4）或小半圆形（如图5），所述透光区121的直径的长度为1.0～10毫米。
实际实施中，所述透光区121的直径的长度可以为1毫米、2毫米、5毫米或其他数值，在此不一一列举。
在另一实施方式中，所述透光区121的整体形状呈椭圆形（如图6）、大半椭圆形（如图7）或小半椭圆形（如图8），所述透光区121的短轴的长度为1.0～10毫米，长轴的长度为1.5～200毫米。
实际实施中，所述透光区121的短轴的长度可以为1毫米、2毫米、5毫米或其他数值，在此不一一列举；长轴的长度可以为1.5毫米、2毫米、5毫米、20毫米、50毫米、100毫米，在此不一一列举。
需要说明的是，所述透光区121的整体形状还可以呈规则的多边形，如矩形（如图9）、三角形或五边形等，所述透光区121的短边的长度为1.0～10毫米，长边的长度为1.5～200毫米。
需要说明的是，实际实施中，所述透光区121的整体形状还可以为方形、圆角矩形或不规则多边形等形状，在此不一一列举。
需要说明的是，图3至图9中仅示意了功能附加区12中设置一个透光区121的情况。
需要说明的是，实际实施中，如图10所示，也可以根据实际需求，例如增加功能附加区12中的像素密度，为了便于对第一像素122进行驱动，或由于工艺条件的限制等因素，功能附加区12中还可以设置两个、三个甚至更多个透光区121。
其中，多个透光区121间隔排布，每个透光区121中均设有第一像素122，每个透光区121的周侧均分布有第一驱动电路1221和信号走线，所述第一驱动电路1221与所述第一像素122电性连接，以用于驱动所述第一像素122。
需要说明的是，透光区121可以阵列排布，也可以随机分布，图11中仅示意了所有透光区121的形状均呈圆形的情况，实际实施中，透光区121的形状可以为上述列举的任意形状，所有透光区121的形状可以相同，也可以不同。
需要说明的是，在功能附加区12中具有多个透光区121时，可根据实际实施中功能附加区12的形状和大小以及透光区121的预设面积选择透光区121的数量。
需要说明的是，功能附加区12的整体透光率与透光区121的数量相关，透光区121的数量越多，功能附加区12中第一驱动电路1221和信号走线分布越零散，第一驱动电路1221和信号走线不透光导致透光率下降，因此，在一实施方式中，可仅在功能附加区12中设置一个透光区121，此时透光区121的单孔面积最大，功能附加区12的整体透光率最高。
如图11和图12所示，所述透光区121的周侧设置有由像素驱动电路聚集而形成的多个像素驱动电路岛30和信号走线。
其中，所述像素驱动电路岛30包括所述第一驱动电路1221，所述信号走线与所述第一驱动电路1221电性连接，以向像素驱动电路岛30输入各种电信号；所述透光区121中未设置像素驱动电路岛30和信号走线。
需要说明的是，第一驱动电路1221的设置需要占据一定的区域面积，通过将第一驱动电路1221相对聚集形成像素驱动电路岛30，可以增加透光区121的面积尺寸；而通过将驱动第一像素122的第一驱动电路1221和信号走线设置在透光区121的周侧，以保证透光区121中不需要设置像素驱动电路岛30，从而防止第一驱动电路1221和信号走线对透光区121的显示和透光造成影响。
需要说明的是，至少部分所述透光区121中设置第一阳极1222是指在一个透光区121或多个透光区121中设置第一阳极1222，实际实施中，也可在所有透光区121中均设置第一阳极1222。
需要说明的是，所述第一驱动电路1221可以用于驱动透光区121中的多个第一像素122，以保证透光区121中不需要设置驱动电路，从而使得透光区121具有高透光率；第一驱动电路1221还可以用于驱动功能附加区12中除透光区121外其他区域中的第一像素122。
需要说明的是，第一驱动电路1221和信号走线可以设置于功能附加区12中，也可以设置于主显示区11中；像素驱动电路岛30除了可以对功能附加区12中的第一像素122进行驱动，也可以负责对主显示区11中的靠近功能附加区12的部分第二像素111进行驱动。
需要说明的是，每个像素驱动电路岛30是将多个像素驱动电路呈岛状集中聚集在一起而形成，而集中聚集在一起是相对于传统技术中像素驱动电路较分散而言的，即相对于传统技术中一个像素对应一个像素驱动电路。像素驱动电路包括多个开关元件、电容器以及信号线等，开关元件可以为薄膜晶体管、二极管或者其他器件。
具体的，信号走线包括多个第一信号线41和多个第二信号线42，第一信号线41和第二信号线42均与像素驱动电路岛30电性连接，以向像素驱动电路岛30输入各种电信号；像素驱动电路岛30通过透明导线与第一阳极1222电性连接，以将电信号传输给第一阳极1222。
其中，第一信号线41可以包括扫描线、控制有机发光二极管发光的发光信号线、控制有机发光二极管的阳极复位的复位线中的至少一种。每个第一信号线41包括第一直线段411、第一迂回段413以及第一过渡段412。
具体的，所述显示面板10还包括多个第一扇形区21和多个第二扇形区22，所述第一扇形区21是由多个第一过渡段412呈扇形排布定义出的区域，所述第二扇形区22是由多个第二过渡段422呈扇形排布定义出的区域。
其中，多个第一直线段411水平平行设置，第一过渡段412位于第一扇形区21，多个第一过渡段412在第一扇形区21呈扇形分布。第一直线段411延伸至第一扇形区21与第一过渡段412电性连接，以使多个第一信号线41集成多组第一信号线41，改变多组第一信号线41的延伸路径以避开透光区121。第一扇形区21中相邻两个第一过渡段412之间的间距小于相邻两个第一直线段411之间的间距。为了避免相邻两个第一过渡段412之间间距较小而出现短路，可以使得第一扇形区21的多个第一过渡段412分成至少两层设置。
其中，第一迂回段413依次电性连接第一组像素驱动电路岛30中的所有像素驱动电路岛30，第一迂回段413也可以是直线，也可以是弧形，或者包括多个折线段。
具体的，第二信号线42可以包括数据线；每个第二信号线42包括第二直线段421、第二迂回段423以及第二过渡段422。
其中，多个第二信号线42的多个第二直线段421竖直平行设置。多个第一信号线41的多个第一直线段411在显示面板10上的垂直投影与多个第二信号线42的多个第二直线段421在显示面板10上的垂直投影互相垂直相交。第二过渡段422位于第二扇形区22，多个第二过渡段422在第二扇形区22呈扇形分布。第二直线段421延伸至第二扇形区22与第二过渡段422电性连接连接，以使多个第二信号线42集成多簇第二信号线42，改变多簇第二信号线42的延伸方向以避开透光区121。第二扇形区22中相邻两个第二过渡段422之间的间距小于相邻两个第二直线段421之间的间距。
多个第二信号线42的多个第二直线段421分成多簇分别延伸至多个第二扇形区22以与多个第二过渡段422电性连接。每簇第一直线段411对应延伸至一个第二扇形区22中。多个第二过渡段422分为多簇，每簇第二过渡段422位于同一个第二扇形区22中。多个第二扇形区22对称设置于功能附加区12相对两侧且靠近第一迂回线设置。多个第二信号线42的第二迂回段423设置于透光区121的边缘。第二过渡段422与第二迂回段423一对一地电性连接。第一迂回段413与第二迂回段423位于不同层。
其中，每簇第二迂回段423的两端分别与一簇第二过渡段422电性连接，即第二迂回段423与第二过渡段422电性连接。
需要说明的是，多个第一迂回段413、多个第二迂回段423以及至少部分像素驱动电路岛30围合成的区域即为透光区121。
进一步地，透光区121对应于第一迂回段413的边缘处的第一组像素驱动电路岛30的边缘凸出或凹陷，以增加功能附加区12中透光区121的透光面积。
如图12所示，显示面板10还包括多个连接线90，连接线90与第二迂回段423位于不同层，每组第二迂回段423包括至少两簇长度不同的第二迂回段423，每簇第二迂回段423的两端分别通过连接线90与第一组像素驱动电路岛30中的两个互相镜像设置的像素驱动电路岛30电性连接，以避免同一组相邻两簇第二迂回段423为了实现与像素驱动电路岛30电性连接，在延伸的过程中相交而出现短路。
如图13和图14所示，图13所示的显示面板10与图11所示显示面板10的结构基本相似，不同之处在于，所述第二信号线42的第二迂回段423呈弧形排布。
具体的，所述第二信号线42的第二迂回段423呈圆弧线设置，此时透光区121的整体形状呈圆形；所述第二信号线42的第二迂回段423呈椭圆弧线设置，此时透光区121的整体形状呈椭圆形。
如图15和图16所示，图15所示的显示面板10与图11所示显示面板10的结构基本相似，不同之处在于，至少部分所述第二信号线42的第二迂回段423环绕整个透光区121设置。
部分像素驱动电路岛30呈环形均匀排列设置于透光区121的边缘。多个第二信号线42的第二迂回段423环绕透光区121设置且与至少部分像素驱动电路岛30依次电性连接。多个第一信号线41的第一迂回段413依次电性连接像素驱动电路岛30中的任意两个相邻的像素驱动电路岛30。
传统技术中，每个显示子像素的下方对应设置一个像素驱动电路，使得多个显示像素对应的多个像素驱动电路分散地分布。通过在透光区121的外围设置多个由像素驱动电路相对集中形成的像素驱动电路岛30，像素驱动电路岛30中的第一驱动电路1221用于驱动透光区121中的多个第一像素122，以使得透光区121中不设置驱动电路，从而使透光区121的透光率提高。多个像素驱动电路岛30的设置也使透光区121的尺寸增加。多个第一信号线41和多个第二信号线42配合多个像素驱动电路岛30设置于透光区121的外围，进一步地提高透光区121的透光率。
本发明的有益效果为：通过对透光区121的形状以及面积进行合理的设置，并对位于透光区121中的第一阳极20的面积进行限制，提高功能附加区12的整体透光率，保证功能附加区12既可以用于显示图像，从而使得显示面板10可以呈现全屏显示的效果，又可以用于安装摄像头等感光元件，提高用户体验。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
