具体实施方式
下面将详细描述本申请的各个方面的特征和示例性实施例，为了使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及具体实施例，对本申请进行进一步详细描述。应理解，此处所描述的具体实施例仅被配置为解释本申请，并不被配置为限定本申请。对于本领域技术人员来说，本申请可以在不需要这些具体细节中的一些细节的情况下实施。下面对实施例的描述仅仅是为了通过示出本申请的示例来提供对本申请更好的理解。
在诸如手机和平板电脑等电子设备上，需要在显示面板10的一侧集成诸如前置摄像头、红外光传感器、接近光传感器等感光组件。在一些实施例中，可以在上述电子设备上设置透光显示区，将感光组件设置在透光显示区背面，在保证感光组件正常工作的情况下，实现电子设备的全面屏显示。
为提高透光显示区的透光率，往往将透光区域的驱动电路设置于非透光区域，这就会导致显示面板中同列的像素单元的驱动电路可能不位于同列，难以实现逐行逐列驱动显示面板的像素单元。
为解决上述问题，本申请实施例提供了一种显示面板及显示装置，以下将结合附图对显示面板及显示装置的各实施例进行说明。
本申请实施例提供一种显示面板，该显示面板可以是有机发光二极管(Organic Light Emitting Diode，OLED)显示面板。
图1示出根据本申请一种实施例的显示面板10的俯视示意图。
如图1所示，显示面板10具有第一显示区AA1、过渡显示区AA2、第二显示区AA3以及围绕第一显示区AA1、过渡显示区AA2、第二显示区AA3的非显示区NA，第一显示区AA1的透光率大于过渡显示区AA2的透光率。可选的，第一显示区AA1的透光率大于第二显示区AA3的透光率。
本文中，第一显示区AA1的透光率大于或等于15％。为确保第一显示区AA1的透光率大于15％，甚至大于40％，甚至具有更高的透光率，本实施例中显示面板10的各个功能膜层的透光率均大于80％，甚至至少部分功能膜层的透光率均大于90％。
根据本申请实施例的显示面板10，第一显示区AA1的透光率大于过渡显示区AA2的透光率，使得显示面板10在第一显示区AA1的背面可以集成感光组件，实现例如摄像头的感光组件的屏下集成，同时第一显示区AA1能够显示画面，提高显示面板10的显示面积，实现显示装置的全面屏设计。
第一显示区AA1和过渡显示区AA2的个数设置方式有多种，例如第一显示区AA1和过渡显示区AA2的个数为1个，用于实现感光组件的屏下集成或者用于实现指纹识别。或者，在另一些可选的实施例中，第一显示区AA1和过渡显示区AA2的个数为两个，其中一组第一显示区AA1和过渡显示区AA2用于实现感光组件的屏下集成，另一组第一显示区AA1和过渡显示区AA2用于实现指纹识别。
请一并参阅图2和图3，图2是图1中Q区域的局部放大结构示意图。图3是图2的局部放大结构示意图。
如图2和图3所示，本申请实施例提供的显示面板10包括：第一像素单元110，位于第一显示区AA1，第一像素单元110包括第一子像素110a、第二子像素110b和第三子像素110c，第一子像素110a、第二子像素110b和第三子像素110c成阵列排布；第一像素电路210，位于过渡显示区AA2，第一像素电路210包括用于驱动第一子像素110a的第一电路211、用于驱动第二子像素110b的第二电路212和用于驱动第三子像素110c的第三电路213，第一电路211、第二电路212和第三电路213在过渡显示区AA2成阵列排布；其中，用于驱动同列第一像素单元110的第一像素电路210位于至少相邻的两列中，且第一电路211、第二电路212的排布规律与其驱动的第一子像素110a、第二子像素110b的排布规律相同。
可选的，第一电路211、第二电路212和第三电路213的排布规律与其驱动的第一子像素110a、第二子像素110b和第三子像素110c的排布规律相同。
在本申请第一方面实施例提供的显示面板10中，用于驱动第一像素单元110的第一像素电路210位于过渡显示区AA2，能够减小第一显示区AA1的布线，提高第一显示区AA1的透光率。第一像素单元110包括第一子像素110a、第二子像素110b和第三子像素110c，通过第一子像素110a、第二子像素110b和第三子像素110c实现显示面板10的彩色化显示。第一像素电路210包括用于驱 动第一子像素110a的第一电路211、用于驱动第二子像素110b的第二电路212和用于驱动第三子像素110c的第三电路213，通过第一电路211、第二电路212和第三电路213驱动第一子像素110a、第二子像素110b和第三子像素110c显示。此外，用于驱动同列第一像素单元110的第一像素电路210位于至少相邻的两列中，使得多个第一像素电路210可以环绕第一显示区AA1设置，减小第一像素电路210和被其驱动的第一像素单元110之间的间距。第一电路211、第二电路212和第三电路213的排布规律与其驱动的第一子像素110a、第二子像素110b和第三子像素110c的排布规律相同，能够简化显示面板10的布线，避免第一像素单元110和第一像素电路210不对应导致的图像显示错乱，提高显示面板10的控制精度和显示效果。
在本申请实施例中，第一电路211、第二电路212和第三电路213的排布规律与其驱动的第一子像素110a、第二子像素110b和第三子像素110c的排布规律相同是指：例如第一子像素110a和第二子像素110b沿第二方向交替排布形成第一像素列，第一电路211和第二电路212沿第二方向排布形成第一电路列，且用于驱动第一像素列的第一电路211和第二电路212沿第二方向交替排布并位于相邻的两列第一电路列中。本申请实施例以第二方向Y为列方向、第一方向X为行方向进行举例说明。
如图3所示，当相邻的两个第一像素列错位设置，使得第一子像素110a和第二子像素110b沿第一方向交替排布时，用于驱动第一像素列的第一电路211和第二电路212沿第二方向交替排布并位于相邻的两个第一电路列中，这就导致第一电路列的排布规律与第一像素列的排布规律不同。
在另一些实施例中，例如多个第三子像素110c沿第二方向排布形成第二像素列，第三电路213沿第二方向排布形成第二电路列，且用于驱动第二像素列的第三电路213沿第二方向排布并位于相邻的两列第二电路列中。
如图3所示，由于第二像素列只有第三子像素110c，第二电路列只有第三电路213，因此即使用于驱动同列第二像素列的第三电路213位于相邻的两个第二电路列中，第二电路列的排布规律也与第二像素列的排布规律相同。
请一并参阅图4和图5，图4示意出另一实施例中图2的局部放大结构示意图，图5是图4的细节结构示意图。图5中略去了部分信号线。
图4和图5中以位于第一显示区AA1的B表示第一子像素110a，以位于过渡显示区AA2的b1表示用于驱动第一子像素110a的第一电路211；以位于第一显示区AA1的R表示第二子像素110b，以位于过渡显示区AA2的r1表示用于驱动第二子像素110b的第二电路212；以位于第一显示区AA1的G表示第三子像素110c，以位于过渡显示区AA2的g1表示用于驱动第三子像素110c的第三电路213。
在另一些可选的实施例中，例如第一子像素110a和第二子像素110b沿第二方向交替排布形成第一像素列，第三子像素110c沿第二方向排布形成第二像素列，第一像素列和第二像素列沿第一方向交替排布。用于驱动同列第一像素单元110的第一像素电路210位于至少相邻的两列中，第一电路211和第二电路212沿第二方向排布形成第一电路列，第三电路213沿第二方向依次排布形成第二电路列。当用于驱动同列第一像素单元110的第一像素电路210位于至少相邻的两列中时，第一电路列和第二电路列可以位于同一列第一像素电路210中，只要用于驱动第一像素列的第一电路211和第二电路212沿第二方向依次交替排布，用于驱动第二像素列的第三电路213沿第二方向依次排布，使得第一电路211、第二电路212和第三电路213的排布规律与其驱动的第一子像素110a、第二子像素110b和第三子像素110c的排布规律相同即可。用于驱动第一像素列的第一电路211和第二电路212可以位于两列第一像素电路210中，用于驱动第二像素列的第三电路213也可以位于两列第一像素电路210中。在一些可选的实施例中，第一电路211与其所驱动的第一子像素110a同行设置，第二电路212与其所驱动的第二子像素110b同行设置，第三电路213与其所驱动的第三子像素110c同行设置。能够简化显示面板10的布线，提高显示面板10的制备效率。
在一些可选的实施例中，如图4所示，显示面板还包括：信号线，包括位于过渡显示区AA2的第一信号线310，第一信号线310连接于用于驱动同列第一像素单元110的多个第一像素电路210；其中，用于驱动同列的第一像素单元110的多个第一像素电路210位于沿第一方向相邻的至少两列及沿第二方向相邻的至少两行中，第一信号线310包括相继连接的第一分部311和第二分部312，第一分部311用于连接位于不同行的第一像素电路210，第二分部312用于连接位于不同列的第一像素电路210，第二分部312的材料包括透明材料。
用于驱动同列第一像素单元110的多个第一像素电路210中，该多个第一像素电路210可以用于驱动一列的第一像素单元110，或者用于驱动相同两列以上的第一像素单元110。
在本申请第一方面实施例提供的显示面板10中，连接第一像素电路210的第一信号线310位于过渡显示区AA2，能够减小第一显示区AA1的布线，提高第一显示区AA1的透光率。第一信号线310包括相继连接的第一分部311和第二分部312，第一分部311用于连接在第二方向上位于不同行的第一像素电路210，那么第一分部311沿第二方向延伸。第二分部312用于连接在第一方向上位于不同列的第一像素电路210，那么第二分部312沿第一方向延伸。第二分部312的材料包括透明材料，能够改善由于第一信号线310弯折导致的第二显示区AA3和过渡显示区AA2之间的显示差异，提高显示面板10的显示效果。
信号线例如为数据线，本申请实施例以信号线为数据线进行举例说明。在其他实施例中，信号线还可以为扫描线。
用于驱动同列的第一像素单元110的多个第一像素电路210位于沿第一方向相邻的至少两列及沿第二方向相邻的至少两行中：同一行内可以具有一个或两个以上的第一像素电路210，同一列内也可以具有一个或两个以上的第一像素电路210。
例如，当第一像素电路210与其连接的第一像素单元110同行设置时，第二分部312连接的两个第一像素电路210位于相邻的两列，第二分部312连接的两个第一像素电路210可以位于相邻的两列或者不相邻的两列。用于驱动同列的第一像素单元110的多个第一像素电路210中，同一行内具有一个第一像素电路210，用一列内具有一个或两个以上的第一像素电路210。
过渡显示区AA2和第二显示区AA3的像素单元对应的数据线通常沿第二方向延伸成型，而第一显示区AA1的像素单元对应的第一信号线310沿弯折路径延伸成型，第一信号线310的第一分部311与过渡显示区AA2和第二显示区AA3的像素单元对应的数据线平行设置，而第二分部312与过渡显示区AA2和第二显示区AA3的像素单元对应的数据线交叉设置，如果第一分部311和第二分部312与过渡显示区AA2和第二显示区AA3的像素单元对应的数据线采用相同的材料(例如金属)制成，就会导致过渡显示区AA2的显示效果与第二显示区AA3存在差异。在本申请实施例中，第二分部312的材料包括透明材料，能够改善由于第一信号线310弯折导致的第二显示区AA3和过渡显示区AA2之间的显示差异，提高显示面板10的显示效果。
此外，用于驱动同列的第一像素单元110的多个第一像素电路210中：至少两个相邻的第一像素电路210沿第一方向分布，至少两个相邻的第一像素电路210沿第二方向分布，即对应于同列的第一像素单元110至少位于相邻两行的第一像素电路210错位设置，这时第一信号线310沿呈台阶状的弯折路径延伸并包括第一分部311和第二分部312。这样设置使得第一信号线310既能够连接于对应于同列的第一像素单元110的多个第一像素电路210，还能够使得相邻两个第一信号线310不会交叉，保证相邻第一信号线310之间相互绝缘。
请参阅图6，图6是图4的部分结构示意图。为了更加清晰的展示第一信号线310的结构，图6与图4不同之处在于没有示意出像素电路和像素单元。
在一些可选的实施例中，如图4至图6所示，多个像素单元还包括位于过渡显示区AA2的过渡像素单元120；像素电路还包括用于驱动过渡像素单元120、并位于过渡显示区AA2的过渡像素电路220；信号线还包括位于过渡显示区AA2的过渡信号线320，过渡信号线320连接于用于驱动同 列过渡像素单元120的多个过渡像素电路220，且位于同列的第一像素单元110和过渡像素单元120对应的第一信号线310和过渡信号线320相互连接。
图4中，以位于过渡显示区AA2的R、G、B表示过渡像素单元120，以位于过渡显示区AA2的r2、g2和b2表示用于驱动过渡像素单元120的过渡像素电路220。
可选的，过渡像素电路220和其驱动的过渡像素单元120对应设置，第一像素电路110和过渡像素电路220的设置位置对应于同一过渡像素单元120，即过渡显示区AA2内部分单个过渡像素单元120对应设置有两个像素电路，部分单个过渡像素单元120对应设置有过渡像素电路220及第一像素电路110。
过渡信号线320的延伸路径设置方式有多种，可选的，过渡信号线320沿直线路径延伸成型，便于过渡信号线320的制备。那么如图4所示，经过过渡显示区AA2并呈直线状的信号线为过渡信号线320，经过过渡显示区AA2并呈弯折状具有第一分部311和第二分部312的为第一信号线310。
用于驱动同列过渡像素单元120的多个过渡像素电路220中，该多个过渡像素电路220可以用于驱动用一列的过渡像素单元120，或者驱动相同两列以上的过渡像素单元120。在这些可选的实施例中，同列的第一像素单元110和过渡像素单元120对应的第一信号线310和过渡信号线320相互连接，同列的第一像素单元110和过渡像素单元120可以使用同列的驱动信号驱动。
在一些可选的实施例中，在对应于同列第一像素单元110和过渡像素单元120的第一信号线310和过渡信号线320中，过渡信号线320位于该列第一像素单元110在第二方向上的至少一侧，第一信号线310沿弯折路径延伸并连接于过渡信号线320。
在这些可选的实施例中，过渡信号线320位于该列第一像素单元110的一侧，第一信号线310位于该列第一像素单元110在第一方向上的一侧，第一信号线310沿弯折路径延伸以后可以连接于过渡信号线320，位于该列的第一像素单元110和过渡像素单元120可以通过同一信号进行驱动，实现逐列驱动。

在本申请第一方面实施例提供的显示面板10中，用于驱动同列第一像素单元110的第一像素电路210在同一环形区域内依次分布，使得对应于同列第一像素单元110的第一信号线310能够在环形区域内依次连接第一像素电路210。由于不同列第一像素单元110对应的第一像素电路210位于不同的环形区域，因此不同的第一信号线310在不同的环形区域内延伸以连接第一像素电路210，使得相邻的两条第一信号线310不会相交，能够避免信号串扰。
在一些可选的实施例中，如图4和图6所示，显示面板10还包括：连接导线400，第一像素电路210与其连接的第一像素单元110同行设置，连接导线400沿第一方向延伸并用于连接第一像素单元110和第一像素电路210，连接导线400的材料包括透明材料。图4和图6中仅示意出了其中一个第一像素单元110和第一像素电路210连接，在图4和图6示出的实施例中，第一像素电路210和第一像素单元110可以一一对应设置。
在这些可选的实施例中，为了使得第一像素电路210和第一像素单元110相互连接，设置了连接导线400。连接导线400的一部分位于第一显示区AA1，连接导线400的另一部分位于过渡显示区AA2。过渡显示区AA2的连接导线400相对于第二显示区AA3来说是多出来的导线，过渡显示区AA2具有部分连接导线400，但是第二显示区AA3没有连接导线400，这就有可能导致过渡显示区AA2和第二显示区AA3之间出现显示差异。连接导线400的材料包括透明材料，一方面能够提高第一显示区AA1的透光率，另一方面能够改善过渡显示区AA2和第二显示区AA3之间的显示差异。
可选的，连接导线400和第二分部312同层设置，能够简化显示面板10的制备工艺，提高显示 面板10的制备效率。
第一信号线310和过渡信号线320的设置方式有多种，在一些可选的实施例中，请一并参阅图7，图7是图1中Q处在另一实施例中的局部放大结构示意图。为了更好的展示第一像素电路210的结构，图7中略去了过渡像素电路220。

在这些可选的实施例中，关于第二对称轴线N对称分布的两列第一像素单元110对应的第一像素电路210位于同一环形区域，且第一像素电路210位于其连接的第一像素单元110背离第二对称轴线N的一侧。因此关于第二对称轴线对称分布的两列第一像素单元110对应的第一像素电路210分设于第二对称轴线N的两侧，这些第一像素电路210即使位于同一环形区域内也不会相互交叉。且在本申请实施例中，第一像素电路210的排布更加规律并便于布置，第一像素电路210的分布也更加均匀，能够改善显示面板10的显色不均问题。
可选的，两条用于连接同一环形区域内的第一像素电路210的过渡信号线320关于第二对称轴线N对称分布。由于关于第二对称轴线N对称分布的两列第一像素单元110对应的第一像素电路210位于同一环形区域，因此同一环形区域内分部有两列第一像素单元110对应的第一像素电路210，需要两条第一信号线310连接这些第一像素电路210。这两条第一信号线310关于第二对称轴线N分布，便于布线设置并便于第一像素电路210和第一信号线310相互连接。
可选的，多个第一像素电路210关于第二对称轴线N对称设置。使得多个第一像素电路210的排布更加均匀，能够进一步改善显示面板10的显色不均问题。
可选的，多个第一像素电路210关于沿第一方向延伸的第一对称轴线M对称设置，第一对称轴线M经过第一显示区AA1的中心。
第一显示区AA1的形状设置方式有多种，第一显示区AA1例如呈正多边形或者圆形。本申请实施例以第一显示区AA1呈圆形为例进行举例说明。在其他实施例中，第一显示区AA1的形状还可以为椭圆形或者正多边形，正多边形例如可以为正方形、等边三角形等。
当第一显示区AA1呈圆形时，环形区域沿第一显示区AA1的边缘延伸呈圆环状，多个第一像素电路210成行成列分布，至少两行相邻的第一像素电路210中，其中一行第一像素电路210的数量大于另一行第一像素电路210的数量。
在这些可选的实施例中，当第一显示区AA1呈圆形时，至少两行相邻的第一像素单元110中，其中一行的第一像素单元110数量大于另一行第一像素单元110的数量。使得第一像素电路210的排布图形与第一像素单元110的排布图形相适配，第一像素电路210的排布更加科学。
可选的，在对应于同列第一像素单元110且位于不同行的多个第一像素电路210中，部分相邻的第一像素电路210错位设置。
在一些实施例中，第一像素电路210的像素电路结构是2T1C电路、7T1C电路、7T2C电路、或9T1C电路中的任一种。本文中，“2T1C电路”指像素电路中包括2个薄膜晶体管(T)和1个电容(C)的像素电路，其它“7T1C电路”、“7T2C电路”、“9T1C电路”等依次类推。
可选的，过渡像素电路220的电路结构是2T1C电路、7T1C电路、7T2C电路、或9T1C电路中 的任一种。
可选的，过渡显示区AA2呈环绕第一显示区AA1设置的圆环状，过渡显示区AA2包括在远离第一显示区AA1圆心方向上等间距设置的多个环形区域。
在这些可选的实施例中，环形区域等间距设置是指多个环形区域的宽度尺寸相同，例如环形区域包括间隔分布的两边缘时，各环形区域两边缘之间的最小距离相同。当第一像素电路210在等间距设置的多个环形区域内分布时，使得多个第一像素电路210的分布更加均衡，显示面板10的显示效果更加均一。
如图7所示，以第一显示区AA1呈圆形，且第一显示区AA1包括8行8列第一像素单元110为例。8行8列第一像素单元110既关于第一对称轴线M对称分布，也关于第二对称轴线N对称分布。用于驱动第一像素单元110的第一像素电路210分设于第二对称轴线N的两侧，并关于第二对称轴线N对称设置。
过渡显示区AA2具有四个环形区域，关于第二对称轴线N对称设置的多个第一像素电路210位于同一环形区域。用于驱动图7中左起第1列第一像素单元110的第一像素电路210和用于驱动图7中左起第8列第一像素单元110的第一像素电路210位于同一、且距离第一显示区AA1最远的环形区域。用于驱动图7中左起第4列第一像素单元110的第一像素电路210和用于驱动图7中左起第5列第一像素单元110的第一像素电路210位于同一、且距离第一显示区AA1最近的环形区域。
可选的，例如图7中左起1列的第一像素单元110为第二像素列，第二像素列包括沿第二方向排布的四个第三子像素110c，那么左起第2列的第一像素单元110为第一像素列，第一像素列包括沿第二方向交替排布的第一子像素110a和第二子像素110b，左起第3列为第二像素列，左起第4列为第一像素列。左起第5列为第二像素列，左起第6列为第一像素列，左起第7列为第二像素列，左起第8列为第一像素列。
其中，相邻的两列第一像素列错位设置，即图7中左起第4列的第一像素列和左起第2列的第一像素列错位设置，使得左起第4列的第一像素列中的第一子像素110a与左起第2列的第二子像素110b沿第一方向对应设置，左起第4列中的第二子像素110b与左起第2列的第一子像素110a沿第一方向对应设置。左起第6列的第一像素列与左起第4列的第一像素列错位设置，左起第6列的第一像素列与左起第2列的第一像素列沿第一方向对齐设置。左起第8列的第一像素列与左起第6列的第一像素列错位设置，左起第8列的第一像素列与左起第4列的第一像素列沿第一方向对齐设置。
由于第一像素电路210在过渡显示区AA2内沿环形区域分布，存在部分第一像素单元110列对应的第一像素电路210列设置于相邻的两列中。例如左起第2列的第一像素列对应的第一电路211和第二电路212位于相邻的两列第一像素电路210中，左起第3列的第二像素列对应的第三电路213位于相邻的三列第一像素电路210中，左起第4列的第一像素列对应的第一电路211和第二电路212位于相邻的三列第一像素电路210中。
由于第一显示区AA1呈圆形，因此至少相邻两行的第一像素单元110数量不同。例如第一显示区AA1内，图7中上起第1行的第一像素单元110个数小于第2行的第一像素单元110个数。那么，第1行第一像素单元110对应的第一像素电路210个数小于第2行的第一像素电路210的个数，第1行第一像素单元110对应的第一像素电路210与第2行的第一像素电路210的在第一方向上错位设置。

在这些可选的实施例中，第一比值与第二比值相等。例如当第一比值为1，一列第二像素单元130对应有一条第二信号线330时，第二比值也为1，一列过渡像素单元120对应有一条第一信号线310或过渡信号线320。能够进一步改善过渡显示区AA2和第二显示区AA3之间的显示差异，提高显示面板10的显示效果。
可选的，当部分第二像素单元130和过渡像素单元120位于同一列时，同列第二像素单元130和过渡像素单元120对应的第二信号线330和过渡信号线320首尾相连。或者同列第二像素单元130和过渡像素单元120对应的第二信号线330和过渡信号线320沿第二方向依次分布。

感光组件可以是图像采集装置，用于采集外部图像信息。例如，感光组件为互补金属氧化物半导体(Complementary Metal Oxide Semiconductor，CMOS)图像采集装置，在其它一些实施例中，感光组件也可以是电荷耦合器件(Charge-coupled Device，CCD)图像采集装置等其它形式的图像采集装置。感光组件可以不限于是图像采集装置，例如在一些实施例中，感光组件也可以是红外传感器、接近传感器、红外镜头、泛光感应元件、环境光传感器以及点阵投影器等光传感器。
根据本申请实施例的显示装置，第一显示区AA1的透光率大于过渡显示区AA2的透光率，使得显示面板10在第一显示区AA1的背面可以集成感光组件，实现例如图像采集装置的感光组件的屏下集成，同时第一显示区AA1能够显示画面，提高显示面板10的显示面积，实现显示装置的全面屏设计。
在另一些可选的实施例中，感光组件还可以为指纹识别传感器。由于第一显示区AA1的透光率较高，使得感光组件能够通过第一显示区AA1获取较为准确的指纹信息。
依照本申请如上文所述的实施例，这些实施例并没有详尽叙述所有的细节，也不限制该发明仅为所述的具体实施例。显然，根据以上描述，可作很多的修改和变化。本说明书选取并具体描述这些实施例，是为了更好地解释本申请的原理和实际应用，从而使所属技术领域技术人员能很好地利用本申请以及在本申请基础上的修改使用。本申请仅受权利要求书及其全部范围和等效物的限制。
