 本发明的实施方式
在此处键入本发明的实施方式描述段落。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。
本申请提供一种显示装置，显示装置100可以为液晶显示装置，也可以为有机发光二极管显示装置。具体地，显示装置100为有机发光二极管显示装置。
请参阅图1及图2所示，图1为本申请实施例显示装置的平面示意图，图2为图1所示显示装置中第一显示像素和第二显示像素的分布示意图。显示装置100具有显示透光区100a、主显示区100c以及过渡显示区100b。显示装置100包括多个第一显示像素、多个第一像素驱动电路（未示出）、多个第二显示像素、多个像素驱动电路岛、多个第一信号线102以及多个第二信号线103。
过渡显示区100b设置于显示透光区100a和主显示区100c之间。主显示区100c和过渡显示区100b均用于显示。显示透光区100a用于显示的同时，还具有高透光特性。显示透光区100a的透光率大于主显示区100c和过渡显示区100b的透光率。主显示区100c的面积大于过渡显示区100b的面积以及显示透光区100a的面积。
显示透光区100a具有弧形边界，显示透光区100a的形状为椭圆形、圆形、倒角正方形或者其他形状。过渡显示区100b为环形。过渡显示区100b为椭圆环形、圆环形或者正方环形中的任意一种。
具体地，显示透光区100a的形状为圆形。显示透光区100a关于第一对称轴A-A和第二对称轴B-B对称设置，第一对称轴A-A与第二对称轴B-B垂直。过渡显示区100b为环形，过渡显示区100b靠近显示透光区100a的边界为圆形。
多个第一显示像素均匀地设置于主显示区100c，每个第一显示像素包括第一红色子像素100c1、第一绿色子像素100c3以及第一蓝色子像素100c2。第一红色子像素100c1、第一绿色子像素100c3以及第一蓝色子像素100c2在主显示区100c呈Pentile设计分布。第一绿色子像素100c3的形状为椭圆形，第一红色子像素100c1和第一蓝色子像素100c2呈八边形。
多个第一像素驱动电路也设置于主显示区100c。一个第一像素驱动电路对应驱动主显示区100c的一个子像素（第一红色子像素100c1、第一绿色子像素100c3以及第一蓝色子像素100c2中的一个）发光。第一像素驱动电路可以采用常见的7T1C、6T1C、5T1C、4T1C、3T1C以及2T1C中的任意一种。每个第一像素驱动电路包括多个金属膜层，且多个第一像素驱动电路阵列地设置于主显示区100c，导致主显示区100c的透光率低。
多个第二显示像素均匀地设置于显示透光区100a和过渡显示区100b。每个第二显示像素包括第二红色子像素100a1、第二绿色子像素100a3以及第二蓝色子像素100a2。第二红色子像素100a1、第二绿色子像素100a3以及第二蓝色子像素100a2在显示透光区100a和过渡显示区100b均呈Pentile设计分布。第二红色子像素100a1、第二绿色子像素100a3以及第二蓝色子像素100a2的形状均为圆形。

与主显示区100c中不同，一个第二像素驱动电路1011可以用于驱动多个第二红色子像素100a1、多个第二绿色子像素100a3以及多个第二蓝色子像素100a2中的至少两个，以减少第二像素驱动电路1011的数目，减少像素驱动电路岛101占用的空间，从而使得显示透光区100a的尺寸可以增大或过渡显示区100b具有过更多的空间。第二像素驱动电路1011可以用于驱动多个第二红色子像素100a1、多个第二绿色子像素100a3以及多个第二蓝色子像素100a2中发出色光相同的子像素和/或发出色光不同的子像素。在显示透光区100a，为同一个第二像素驱动电路1011驱动的子像素通过透明导线电性连接。

多个第一信号线102从主显示区100c延伸至过渡显示区100b，且多个第二信号线103从主显示区100c延伸至过渡显示区100b，多个第一信号线102和多个第二信号线103不设置于显示透光区100a。多个第一信号线102和多个第二信号线103的制备材料均为金属，金属包括但不限于钼、铝、钛以及铜。多个第一信号线102以及多个第二信号线103不设置于显示透光区100a，进一步地提高显示透光区100a的透光率。
具体地，第一信号线102为数据线，数据线用于传输数据信号。第二信号线103选自扫描线、复位线以及发光控制信号线中的至少一种，其中，扫描线用于传输扫描信号，复位线用于传输复位信号和/或初始化信号，发光控制信号线用于传输发光控制信号。
在主显示区100c，多个第一信号线102与多个第二信号线103垂直相交，多个第一信号线102相互平行且任意相邻两个第一信号线102之间的间距相等，且多个第二信号线103相互平行且任意相邻两个第二信号线103之间的间距相等，多个第二信号线103与多个第一信号线102垂直相交。
在过渡显示区100b，由于多个第二像素驱动电路1011组成多个像素驱动电路岛101，每个像素驱动电路岛101是与多个第一信号线102中的至少两个电性连接，且与多个第二信号线103中的至少两个电性连接，使得多个第一信号线102延伸至过渡显示区100b时需要调整且分为多组第一信号线102，每组第一信号线102与一个像素驱动电路岛101连接，且多个第二信号线103延伸至过渡显示区100b时需要换线且分为多组，每组第二信号线103串接多个像素驱动电路岛101。
如图3以及图4所示，每个第一信号线102包括第一连接段1021，多个第一信号线102的第一连接段1021连接多个像素驱动电路岛101，以使数据信号传输至多个像素驱动电路岛101的第二像素驱动电路1011，多个第一信号线102的第一连接段1021设置于多个像素驱动电路岛101和显示透光区100a之间。
相对于公开号为CN110491917A的中国专利中多个第二信号线的第二迂回段设置于像素驱动电路岛的外围时，多个第二信号线的第二迂回段需要通过换线以与对应的像素驱动电路岛连接会增加布线的复杂程度，且多个第二信号线的第二迂回段的长度较长会使得导致具有第二迂回段的第二信号线与主显示区的第二信号线之间的阻抗差异较大，导致主显示区出现显示不均的问题。本申请将多个第一信号线102的第一连接段1021设置于多个像素驱动电路岛101和显示透光区100a之间，使得多个第一信号线102的第一连接段1021不需要换线就可以直接与对应的像素驱动电路岛101连接，使得多个第一信号线102的第一连接段1021的布线复杂程度减小，且多个第一信号线102的第一连接段1021设置于多个像素驱动电路岛101和显示透光区100a之间使得多个第一信号线102的第一连接段1021的长度减小，改善多个第一信号线102的第一连接段1021的长度过长导致具有第一连接段1021的第一信号线102与主显示区100c的第一信号线的阻抗差异较大的问题，从而改善主显示区100c中与具有第一连接段1021的第一信号线102连接的像素和与直线形第一信号线连接的像素之间存在显示的不均问题。
请结合图3和图6，图6为主显示区和过渡显示区交界处的局部放大示意图。每个第一信号线102还包括第一过渡段1022，多个第一信号线102的第一过渡段1022设置于多个像素驱动电路岛101和主显示区100c之间，且与多个像素驱动电路岛101连接。一方面，部分第一信号线102的第一过渡段1022相对于主显示区100c的第一信号线102调整以适应第一信号线102分别与主显示区100c的第一像素驱动电路和过渡显示区100b的像素驱动电路岛101连接时存在的差异，第一过渡段1022的布设需要占用多个像素驱动电路岛101和主显示区100c之间的空间以进行调整进而与多个像素驱动电路岛101连接。另一方面，多个像素驱动电路岛101更加靠近显示透光区100c的中心位置设置，保证对应显示透光区100a中心位置第二显示像素的像素驱动电路岛101中的第二像素驱动电路1011能驱动中心位置处的第二显示像素。
至少部分第一过渡段1022包括扇形区段10221和与扇形区段10221连接的直线区段10222，多个第一过渡段1022的扇形区段10221聚集且呈扇形分布，收窄成一组第一信号线102，且通过多个第一过渡段1022的直线区段10222与像素驱动电路岛101连接。
多个像素驱动电路岛101环绕显示透光区100a分布，以使多个像素驱动电路岛101适应显示透光区100a的形状设置，减少多个像素驱动电路岛101中的第二像素驱动电路1011与对应的子像素之间的间距，从而减小连接第二像素驱动电路1011与对应子像素的导线的阻抗，提高第二显示像素的发光的均一性。
如图4所示，多个像素驱动电路岛101包括第一组像素驱动电路岛101a和第二组像素驱动电路岛101b，第一组像素驱动电路岛101a中的像素驱动电路岛101呈弧形分布，第二组像素驱动电路岛101b中的像素驱动电路岛101呈弧形分布，第一组像素驱动电路岛101a中的像素驱动电路岛101与第二组像素驱动电路岛101b中的像素驱动电路岛101关于第二对称轴B-B对称设置。第一组像素驱动电路岛101a中的像素驱动电路岛101关于第一对称轴A-A对称设置。第二组像素驱动电路岛101b中的像素驱动电路岛101关于第一对称轴A-A对称设置。每个第一信号线102的连接段连接于第一组像素驱动电路岛101a中的像素驱动电路岛101和第二组像素驱动电路岛101b中对应的像素驱动电路岛101之间，使得数据信号在第一组像素驱动电路岛101a中的像素驱动电路岛101和第二组像素驱动电路岛101b中对应的像素驱动电路岛101之间传输。
从靠近第一对称轴A-A至远离第一对称轴A-A的方向上，第一组像素驱动电路岛101a中的至少部分像素驱动电路岛101中的第二像素驱动电路1011的数目递减；从靠近第一对称轴A-A至远离第一对称轴A-A的方向上，第二组像素驱动电路岛101b中的至少部分像素驱动电路岛101中的第二像素驱动电路1011的数目递减，以使包括较多第二像素驱动电路1011的像素驱动电路岛101可以对应驱动更多第二显示像素的子像素，包括较少第二像素驱动电路1011的像素驱动电路岛101可以对应驱动较少第二显示像素的子像素，适应显示透光区100a中从靠近第一对称轴A-A至远离第一对称轴A-A的第二显示像素的子像素的数目递减且像素驱动电路岛101的部分第二像素驱动电路1011驱动显示透光区100a中与像素驱动电路岛101对应的第二显示像素（像素驱动电路岛101正下方或正上方的第二显示像素）时，部分像素驱动电路岛101驱动显示透光区100c的子像素的数目从靠近第一对称轴A-A至远离第一对称轴A-A发生递减的情况。第一组像素驱动电路岛101a中的像素驱动电路岛101和第二组像素驱动电路岛101b中对应的像素驱动电路岛101用于驱动两者所在位置处、两者之间以及两者附近的第二显示像素。
具体地，多个像素驱动电路岛101呈条状，多个像素驱动电路岛101的宽度相同，从靠近第一对称轴A-A至远离第一对称轴A-A的方向上，第一组像素驱动电路岛101a中的至少部分像素驱动电路岛101的高度递减；从靠近第一对称轴A-A至远离第一对称轴A-A的方向上，第二组像素驱动电路岛101b中的至少部分像素驱动电路岛101的高度递减。每个像素驱动电路岛101的宽度可以为60微米-100微米，例如宽度为70微米。
第一组像素驱动电路岛101a中靠近第一对称轴A-A的部分相邻像素驱动电路岛101的高度相同，第二组像素驱动电路岛101b中靠近第一对称轴A-A的部分相邻像素驱动电路岛101的高度相同，以适应靠近第一对称轴A-A的过渡显示区100b和显示透光区100a中对应位置的第二显示像素的数目相同且像素驱动电路岛101驱动的第二显示像素的子像素数目相同的情况。
第一组像素驱动电路岛101a中至少部分像素驱动电路岛101中的任意相邻两个像素驱动电路岛101之间的间距均相等；第二组像素驱动电路岛101b中至少部分像素驱动电路岛101中的任意相邻两个像素驱动电路岛101之间的间距均相等。
具体地，第一组像素驱动电路岛101a和第二组像素驱动电路岛101b中靠近第一对称轴A-A的相邻两个像素驱动电路岛101之间的间距为50微米-70微米，例如间距为60微米。
在从靠近第一对称轴A-A至远离第一对称轴A-A的方向上，至少部分第一组像素驱动电路岛101a中的像素驱动电路岛101与第二组像素驱动电路岛101b中对应的像素驱动电路岛101之间的间距递减，以使得多个像素驱动电路岛101环绕显示透光区100a设置时适应显示透光区100a的圆形设计的同时，有利于缩短连接第一组像素驱动电路岛101a中的像素驱动电路岛101与第二组像素驱动电路岛101b中对应的像素驱动电路岛101之间的第一信号线102的长度，避免第一信号线102的连接段1021长度较长导致阻抗较大进而影响显示效果。
第一组像素驱动电路岛101a包括靠近第一对称轴A-A且相邻设置的第一像素驱动电路岛101a1和第二像素驱动电路岛101a2，第二组像素驱动电路岛101b包括与第一像素驱动电路岛101a1对应设置的第三像素驱动电路岛101b1和与第二像素驱动电路岛101a2对应设置的第四像素驱动电路岛101b2，第一像素驱动电路岛101a1与第三像素驱动电路岛101b1之间的间距等于第二像素驱动电路岛101a2与第四像素驱动电路岛101b2之间的间距。第一像素驱动电路岛101a1包括的第二像素驱动电路1011的数目与第三像素驱动电路岛101b1包括的第二像素驱动电路1011的数目相同。第二像素驱动电路岛101a2包括的第二像素驱动电路1011的数目与第四像素驱动电路岛101b2包括的第二像素驱动电路1011的数目相同。
多个第一信号线102的第一连接段1021包括第一组迂回连接段102a和第二组迂回连接段102b，第一组迂回连接段102a与第二组迂回连接段102b位于显示透光区100a的相对两侧且关于第一对称轴A-A对称设置，且第一组迂回连接段102a和第二组迂回连接段102b均环绕显示透光区100a设置，第一组迂回连接段102a和第二组迂回连接段102b均设置于显示透光区100a和多个像素驱动电路岛101之间，第一组迂回连接段102a中的第一连接段1021关于第二对称轴B-B对称设置，第二组迂回连接段102b中的第一连接段1021关于第二对称轴B-B对称设置。第一组迂回连接段102a中的第一连接段1021和第二组迂回连接段102b中的第一连接段1021均为弧线，以使第一信号线102避开显示透光区100a设置的同时，第一组迂回连接段102a中的第一连接段1021和第二组迂回连接段102b中的第一连接段1021的形状与显示透光区100a的形状适应使得第一连接段1021的长度最小化，减少具有第一组迂回连接段102a和第二组迂回连接段102b中的第一连接段1021的第一信号线102的长度与主显示区100c的第一信号线102的长度的差异，进而最大程度地改善主显示区100c由于阻抗差异导致显示不均的问题。
在从靠近第二对称轴B-B至远离第二对称轴B-B的方向上，第一组迂回连接段102a中的第一连接段1021的数目递减，第二组迂回连接段102b中的第一连接段1021的数目递减，以使第一组像素驱动电路岛101a中靠近第一对称轴A-A的像素驱动电路岛101与第二组像素驱动电路101b中对应的像素驱动电路岛101之间通过具有长度更长的弧线形第一连接段1021连接，第一组像素驱动电路岛101a中远离第一对称轴A-A的像素驱动电路岛101与第二组像素驱动电路岛101b中对应的像素驱动电路岛101之间通过具有长度更短的弧线形第一连接段1021连接，使得多个第一连接段1021串接第一组像素驱动电路岛101a中的像素驱动电路岛101与第二组像素驱动电路101b中对应的像素驱动电路岛101的同时，多个第一连接段1021的长度最小化，进而改善主显示区100c的显示差异，且避免多个第一连接段1021之间短路。
多个第一信号线102的第一连接段1021还包括直线连接段10211，一部分直线连接段10211连接于第一组像素驱动电路岛101a中的像素驱动电路岛101与第二组像素驱动电路岛101b中对应的像素驱动电路岛101之间，且位于第一组迂回连接段102a以及第二组迂回连接段102b远离显示透光区100a的一侧。相对于背景技术中多个第二信号线的第二迂回段全部为绕线设计，本申请中部分连接段为直线连接段，更进一步地减小第一信号线的阻抗差异导致的显示不均问题。
另一部分直线连接段10211连接于第一组迂回连接段102a和第二组迂回连接段102b中的第一连接段1021与多个像素驱动电路岛101之间，以进一步地缩短多个第一信号线102的第一连接段1021的长度，进一步地减小第一信号线的阻抗差异，进一步地改善主显示区100c的显示不均问题。
结合图4、图6以及图7，图7为图1所示显示装置的第二种局部示意图，延伸至过渡显示区100b的第二信号线103分成多组，每组串接对应的像素驱动电路岛101，以使扫描信号传输至相互串接的像素驱动电路岛101。每个第二信号线103包括连接第一组像素驱动电路岛101a和第二组像素驱动电路岛101b中相邻两个像素驱动电路岛101的第二连接段1031，第二连接段1031可以为直线、折线或者弧形。每个第二信号线103还包括第二过渡段1032，多个第二信号线103的第二过渡段1032设置于多个像素驱动电路岛101和主显示区100c之间。
在从靠近第一对称轴A-A至远离第一对称轴A-A的方向上，与第一组像素驱动电路岛101a中的至少部分像素驱动电路岛101电性连接的第二信号线103的数目递减；在从靠近第一对称轴A-A至远离第一对称轴A-A的方向上，与第二组像素驱动电路岛101b中的至少部分像素驱动电路岛101电性连接的第二信号线103的数目递减，以适应部分靠近第一对称轴A-A的像素驱动电路岛101包括的第二像素驱动电路1011较多，而远离第一对称轴A-A的像素驱动电路岛101包括的第二像素驱动电路1011较少。
本申请还提供一种电子设备，电子设备包括显示装置100以及感光单元，感光单元对应显示透光区100a设置。感光单元为摄像头、光学触控组件以及光学指纹识别传感器等。具体地，感光单元为摄像头。显示透光区100a具有高透光率，能减小光的干涉和衍射，有利于提升电子设备的拍照效果。
