Description

显示面板及电子装置 技术领域
本发明涉及显示技术领域，尤其涉及一种显示面板及电子装置。
 背景技术
随着显示技术的不断发展，有机发光二极管（organic light-emittingdiode,OLED）显示面板逐渐占据了智能手机应用的主要地位，其外观形态逐渐向高屏占比的全面屏发展。为了提高显示面板的屏占比，屏下摄像（camera under panel,CUP）技术成为各大面板生产厂商的关注热点，采用屏下摄像技术的智能终端产品也已经进入了消费市场。
 技术问题
在当前采用屏下摄像技术的显示面板中，为了提高摄像头的成像效果，显示面板中显示区的像素阵列会被用于屏下摄像的感光区分隔开，以此提高摄像头正上方显示面板的透过率，增强摄像头的光线收集能力。由于像素阵列被分隔开后，位于像素阵列边缘且靠近感光区的像素驱动电路与位于像素阵列内部的像素驱动电路所处的环境存在差异，导致靠近感光区的像素驱动电路中的薄膜晶体管的电信号与位于像素阵列内部的像素驱动电路中的薄膜晶体管的电信号不一致，使得位于像素阵列边缘且靠近感光区的像素驱动电路控制的发光单元存在突变，导致像素阵列在靠近感光区的边缘与像素阵列内部产生显示亮度不均的问题。
综上所述，现有显示面板及电子装置存在屏下摄像区域显示亮度不均的问题。故，有必要提供一种显示面板及电子装置来改善这一缺陷。

在本申请实施例中，显示区10中仅具有一个附加功能区11，附加功能区11可以设置于显示区10的任意区域。在实际应用中，显示区10中具有的附加功能区11的数量不仅限于上述的1个，也可以为2个及以上。当显示区10中设置有多个附加功能区11时，每个附加功能区11除显示功能外，可以具有的传感功能可以不同也可以相同，各个附加功能区11可以设置在一起也可以分散设置。
在本申请实施例中，光学传感器可以为摄像头，如此可以在提高显示面板的屏占比的同时，实现屏下摄像的功能。在实际应用中，光学传感器的类型不仅限于上述的摄像头，还可以包括但不限于指纹传感器、红外传感器、激光传感器等。
如图1所示，附加功能区11包括过渡显示区111和透光显示区112，过渡显示区111设置于透光显示区112的外围，主显示区12设置于过渡显示区111的外围。
在本申请实施例中，过渡显示区111为环形，透光显示区112为圆形。在实际应用中，透光显示区112的形状不仅限于圆形，还可以为矩形、圆角矩形或不规则多边形等。
进一步的，如图2所示，图2为本申请实施例提供的附加功能区的第一种结构示意图，所述显示面板100还包括多个第一显示像素以及多个第一像素驱动电路13，多个所述第一显示像素可以设置于过渡显示区111和透光显示区112，多个所述第一像素驱动电路13用于驱动过渡显示区111和透光显示区112内的多个所述第一显示像素发光，以使过渡显示区111和透光显示区112均可以实现画面显示的功能。
多个所述第一像素驱动电路13设置于所述过渡显示区111，以保证透光显示区112内不需要设置第一像素驱动电路13，从而减少或避免第一像素驱动电路13中的金属膜层或其他不透光膜层对光线的反射，提高透光显示区112的光线透过率。
在本申请实施例中，每个所述第一像素驱动电路13与对应的一个所述第一显示像素电连接，以驱动对应的一个所述第一显示像素发光。在实际应用中，每个所述第一像素驱动电路13电连接的第一显示像素的数量不仅限于上述的1个，每个第一像素驱动电路13还可以与对应的2个及以上的第一显示像素电连接，以驱动对应的2个及以上的第一显示像素发光。
在本申请实施例中，附加功能区11内仅设置有一个透光显示区112，光学传感器与附加功能区11中的透光显示区112对位设置。在实际应用中，若显示面板100具有多个光学传感器时，附加功能区11内可以设置有相互间隔设置的多个透光显示区112。
在本申请实施例中，每个第一像素驱动电路13包括器件以及布线，器件可以包括开关元件以及电容器，布线可以包括信号走线。开关元件可以包括薄膜晶体管或二极管等其他开关器件。
在本申请实施例中，每一个第一显示像素可以包括第一红光子像素、第一绿光子像素和第一蓝光子像素，第一红光子像素、第一绿光子像素和第一蓝光子像素均为有机发光二极管。在实际应用中，第一红光子像素、第一绿光子像素和第一蓝光子像素不仅限于上述的有机发光二极管，还可以为迷你发光二极管或微发光二极管等发光器件中的任意一种。
主显示区12中包括多个第二显示像素以及多个第二像素驱动电路，所述第二像素驱动电路与对应的所述第二显示像素电连接，多个所述第二像素驱动电路用于驱动多个所述第二显示像素发光。
在本申请实施例中，每个所述第二显示像素可以包括第二红光子像素、第二绿光子像素和第二蓝光子像素，第二红光子像素、第二绿光子像素和第二蓝光子像素均为有机发光二极管。在实际应用中，第二红光子像素、第二绿光子像素和第二蓝光子像素不仅限于上述的有机发光二极管，还可以为迷你发光二极管或微发光二极管等发光器件中的任意一种。
在本申请实施例中，每个第二像素驱动电路包括器件以及布线，器件可以包括开关元件以及电容器，布线可以包括信号走线。开关元件可以包括薄膜晶体管或二极管等其他开关器件。
进一步的，透光显示区112中的第一显示像素的像素密度可以小于主显示区12中的第二显示像素的像素密度；和/或，透光显示区112中任意相邻两个第一显示像素之间的间距大于主显示区12中任意相邻两个第二显示像素的间距；和/或，透光显示区112的第一显示像素的尺寸可以小于主显示区12中的第二显示像素的尺寸，以使透光显示区112的透光率大于主显示区12的透光率。
进一步的，过渡显示区111中的第一像素驱动电路13的密度可以大于主显示区12中的第二像素驱动电路的密度，以使原本设置于透光显示区112中的第一像素驱动电路可以全部设置于过渡显示区111中，从而可以进一步提高透光显示区112的透光率。
如图2所示，过渡显示区111中的多个所述第一像素驱动电路13沿第一方向y延伸设置成列，多列所述第一像素驱动电路13沿第二方向x排布设置，所述第一方向y与所述第二方向x不同。
在本申请实施例中，所述第一方向y垂直于所述第二方向x。在实际应用中，所述第一方向y可以与第二方向x交叉但不垂直。
进一步的，所述显示面板还包括多个虚拟像素驱动电路14，所述虚拟像素驱动电路14设置于所述过渡显示区111。每列所述第一像素驱动电路13中，至少部分所述第一像素驱动电路13在所述第二方向x至少一侧边的预设距离范围内，具有相邻设置的所述第一像素驱动电路13或相邻设置的所述虚拟像素驱动电路。
需要说明的是，所述预设距离范围指的是过渡显示区111中任意相邻两列所述第一像素驱动电路13的中线之间的距离或者任意相邻两列所述第一像素驱动电路13同一侧之间的距离。图2至图4中采用多个矩形表示第一像素驱动电路13以及虚拟像素驱动电路14，并不代表实际应用中的第一像素驱动电路13和虚拟像素驱动电路14的形状，并且图2至图4仅对过渡显示区111中的部分第一像素驱动电路13和虚拟像素驱动电路14的排布方式进行了示意，并不代表实际应用中第一像素驱动电路13以及虚拟像素驱动电路14的数量。
以图2所示的附加功能区11为例进行说明，过渡显示区内具有m列第一像素驱动电路13，m为正整数且大于或等于6。图2中仅示意了依次并排设置的第(n-2)列、第(n-1)列、第n列、以及依次并排设置的第(n+1)列、第(n+2)列和第(n+3)列第一像素驱动电路13。多个虚拟像素驱动电路14包括第一虚拟像素驱动电路141和第二虚拟像素驱动电路142。
第(n-1)列第一像素驱动电路13中，各个第一像素驱动电路13在第二方向x左侧的预设距离范围内均设置有第一像素驱动电路13，在第二方向x的右侧均设置有第一像素驱动电路13。第n列第一像素驱动电路13中，各个第一像素驱动电路13在第二方向x右侧的预设距离范围内均设置有第一虚拟像素驱动电路141。
第(n+1)列第一像素驱动电路13中，各个第一像素驱动电路13在第二方向x左侧的预设距离范围内均设置有第二虚拟像素驱动电路142，在第二方向x右侧的预设距离范围内均设置有第一像素驱动电路13。
如图2所示，当附加功能区11未设置透光显示区112时，第n列的第一像素驱动电路13与第(n+1)列的第一像素驱动电路13相邻，此时第n列第一像素驱动电路13中各个第一像素驱动电路13在第二方向x左右两侧均设置有第一像素驱动电路13，以使第n列第一像素驱动电路13与第(n-1)列第一像素驱动电路13所处的电路环境相同，即第n列第一像素驱动电路13所受到的耦合电容、相邻第一像素驱动电路13中信号跳变带来的干扰与第(n-1)列相同，此时第n列的第一像素驱动电路13控制的第一显示像素的亮度可以与第(n-1)列第一像素驱动电路13控制的第一显示像素的亮度相同或相近。
基于上述相同的原因，位于第(n+1)列第一像素驱动电路13控制的第一显示像素也能够与第(n+2)列第一像素驱动电路13控制的第一显示像素保持相同或相近的亮度，此时显示面板在附加功能区11的显示亮度可以保持一致。
如图2所示，当设置透光显示区112后，由于透光显示区112内不能设置有第一像素驱动电路13，透光显示区112将第n列第一像素驱动电路13中的部分第一像素驱动电路13与第(n+1)列第一像素驱动电路13中的部分第一像素驱动电路13间隔开。由于透光显示区112内并未设置有第一像素驱动电路13，使得第n列第一像素驱动电路中的第一像素驱动电路13的右侧以及第(n+1)列第一像素驱动电路13中的第一像素驱动电路13的左侧并未设置有第一像素驱动电路13，导致第n列的第一像素驱动电路13与第(n-1)列中的第一像素驱动电路13所处的电路环境不同，同时也导致第(n+1)列的第一像素驱动电路13与第(n+2)列中的第一像素驱动电路13所处的电路环境不同，进而导致第n列第一像素驱动电路13以及第(n+1)第一像素驱动电路13控制的第一显示像素的发光亮度与过渡显示区111中其他列第一像素驱动电路13控制的第一显示像素的发光亮度的差异增大，最终导致显示面板100在附加功能区11内出现显示亮度不均的问题。
通过在第n列的第一像素驱动电路13中的各个第一像素驱动电路13右侧的预设距离范围内设置有第一虚拟像素驱动电路141，以及在位于第(n+1)列第一像素驱动电路13中的各个第一像素驱动电路13左侧的预设距离范围内设置第二虚拟像素驱动电路142，第一虚拟像素驱动电路141和第二虚拟像素驱动电路142均可以与第一像素驱动电路13一同接收数据信号和扫描信号，但第一虚拟像素驱动电路141和第二虚拟像素驱动电路142均不参与控制第一显示像素发光，如此可以在保证附加功能区11的显示效果的情况下，使得第n列的第一像素驱动电路13的左右两侧均设置有像素驱动电路，第(n+1)列的第一像素驱动电路13的左右两侧也同样都设置有像素驱动电路，如此可以减小第n列的第一像素驱动电路13与第(n-1)列中的第一像素驱动电路13所处的电路环境之间的差异，以及减小第(n+1)列的第一像素驱动电路13与第(n+2)列的第一像素驱动电路子像素13所处的电路环境之间的差异，避免第n列的第一像素驱动电路13和第(n+1)列的第一像素驱动电路13的信号发生突变，从而改善附加功能区11内存在的显示亮度不均的问题。
进一步的，显示面板还包括多条数据线16，所述数据线16沿所述第一方向y延伸，多条所述数据线16沿所述第二方向x间隔排布设置。多个所述虚拟像素驱动电路14沿所述第一方向y延伸设置成列，位于同一列的多个所述虚拟像素驱动电路14连接于同一条所述数据线16。
多列所述第一像素驱动电路13中的至少两列所述第一像素驱动电路13在所述第二方向x一侧边的所述预设距离内具有相邻设置的至少一列所述虚拟像素驱动电路14，一列所述虚拟像素驱动电路14与其相邻的一列所述第一像素驱动电路分别与两条相邻的所述数据线16电连接。
如图2所示，在所述过渡显示区111中，沿着第二方向x，位于最靠近透光显示区112的第n列所述第一像素驱动电路13与所述透光显示区112之间设置有对应的一列第一虚拟像素驱动电路141，位于该列第一虚拟像素驱动电路141中的多个所述第一虚拟像素驱动电路141均连接于同一条数据线。位于最靠近透光显示区112的第(n+1)列第一像素驱动电路13与所述透光显示区112之间同样设置有对应的一列第二虚拟像素驱动电路142，位于该列所述第二虚拟像素驱动电路142中的多个所述第二虚拟像素驱动电路142均连接于同一条数据线16。
进一步的，沿所述第二方向x，位于所述透光显示区112一侧的一列所述虚拟像素驱动电路14与位于所述透光显示区另一侧的一列所述第一像素驱动电路13对应的所述数据线16电连接。
在一实施例中，如图2所示，第n列第一像素驱动电路13与对应的第n条数据线电连接，第(n+1)列第一像素驱动电路13与对应的第(n+1)条数据线电连接。沿所述第二方向x，位于所述透光显示区112左侧的一列所述第一虚拟像素驱动电路141通过信号走线绕过透光显示区112的相对端，与位于所述透光显示区112右侧且最靠近所述透光显示区112的第(n+1)列第一像素驱动电路13对应的第(n+1)条数据线电连接。位于透光显示区112右侧的一列所述第二虚拟像素驱动电路142通过信号走线绕过透光显示区112的相对端，与位于透光显示区112左侧且最靠近透光显示区112的第n列第一像素驱动电路13对应的第n条数据线电连接。
在实际应用中，过渡显示区111内可以设置有m条数据线16，m为正整数且大于或等于6。图2中仅示意出第(n-2)条、第(n-1)条、第n条、第(n+1)条、第(n+2)条以及第(n+3)条数据线16，位于第n列第一像素驱动电路13右侧的一列所述第一虚拟像素驱动电路141可以通过信号走线绕过透光显示区112的相对端与位于透光显示区112另一侧的第a条数据线电连接，其中a大于或等于n+1且小于或等于m。当a=n+1时，位于第n列第一像素驱动电路13右侧的一列所述第一虚拟像素驱动电路141可以与第(n+1)列第一像素驱动电路13共同连接于第(n+1)条数据线，当a=n+2或n+3时，位于第n列第一像素驱动电路13右侧的一列第一虚拟像素驱动电路141还可以与第n+2或n+3条数据线电连接。
位于第(n+1)列第一像素驱动电路13左侧的一列第二虚拟像素驱动电路142可以与位于透光显示区112另一侧的第b条数据线电连接，其中b大于或等于1且小于或等于n。当b=n时，位于第(n+1)列第一像素驱动电路13左侧的一列第二虚拟像素驱动电路142与第n列第一像素驱动电路连接于第n条数据线，当b=n-1或n-2时，位于第(n+1)列第一像素驱动电路13左侧的一列第二虚拟像素驱动电路142还可以与第n-1或n-2条数据线电连接。如此可以使得第n列以及第(n+1)列第一像素驱动电路13所处的电路环境与功能附加区11中未设置透光显示区112时第n列以及第(n+1)列第一像素驱动电路13所处的电路环境相同，以此避免第n列第一像素驱动电路13和第(n+1)列第一像素驱动电路13的信号发生突变，从而改善附加功能区11内存在的显示亮度不均的问题。
位于透光显示区112一侧的一列虚拟像素驱动电路还可以与位于透光显示区112同一侧的一列第一像素驱动电路13对应的数据线电连接。
在一实施例中，如图3所示，图3为本申请实施例提供的附加功能区的第二种结构示意图，位于透光显示区112左侧的一列第一虚拟像素驱动电路141（即第n列第一像素驱动电路靠近第(n+1)列第一像素驱动电路的侧边设置的一列第一虚拟像素驱动电路141）与位于透光显示区同侧的第a列第一像素驱动电路13对应的第a条数据线电连接，其中a大于或等于且小于或等于n-1。当a=n-1时，位于透光显示区112左侧的一列第一虚拟像素驱动电路141与第(n-1)列第一像素驱动电路13对应的第(n-1)条数据线电连接，a还可以为n-2或n-3等。
位于透光显示区112右侧的一列第二虚拟像素驱动电路142（即第(n+1)列第一像素驱动电路13靠近第n列第一像素驱动电路的侧边设置的一列第二虚拟像素驱动电路142）与第b列第一像素驱动电路13对应的第b条数据线电连接，其中b大于或等于n+2且小于或等于m。当b等于n+2时，位于透光显示区112右侧的一列第二虚拟像素驱动电路142与第(n+2)列第一像素驱动电路13对应的第(n+2)条数据线电连接，b还可以为n+3或n+4等。
在一实施例中，如图4所示，图4为本申请实施例提供的附加功能区的第三种结构示意图，第n列第一像素驱动电路13的右侧设置有相邻的两列第一虚拟像素驱动电路141，该两列所述第一虚拟像素驱动电路141分别与第(n+1)列和第(n+1)列第一像素驱动电路对应的第(n+1)条以及第(n+2)条数据线电连接。第(n+1)列第一像素驱动电路13的左侧同样也设置有相邻的两列所述第二虚拟像素驱动电路142，该两列第二虚拟像素驱动电路142分别与第n条和第(n-1)条数据线16电连接。
在实际应用中，第n列第一像素驱动电路13的右侧以及第(n+1)列第一像素驱动电路13的左侧分别可以设置的虚拟像素驱动电路14的列数不仅限于上述实施例中的1列或2列，也可以为3列及以上，此处不做限制。
在本申请实施例中，在一实施例中，如图5所示，图5为本申请实施例提供的附加功能区的第三种结构示意图，所述过渡显示区111内设有多个间隔分布的像素驱动电路岛15，每个所述像素驱动电路岛15包括多个第一像素驱动电路13，相邻所述像素驱动电路岛15之间的距离大于所述预设距离范围。所述像素驱动电路岛15在第二方向靠近相邻所述像素驱动电路岛的一侧边缘设有一列对应的虚拟像素驱动电路14。
需要说明的是，每个像素驱动电路岛15是将多个第一像素驱动电路13呈岛状集中聚集在一起而形成，而呈岛状集中聚集在一起是相对于传统像素驱动电路较分散而言的，即相对于传统技术中一个子像素对应一个驱动电路而言的。
图5中仅示出了两个相邻设置的像素驱动电路岛，分别为第一像素驱动电路岛151和第二像素驱动的电路岛152，第一像素驱动电路岛151具有第(n-2)列、第(n-1)列以及第n列第一像素驱动电路13，第二像素驱动电路岛152具有第(n+1)列、第(n+2)列以及第(n+3)列第一像素驱动电路13，第一像素驱动电路岛151与第二像素驱动电路岛152之间的距离大于相邻两列所述第一像素驱动电路13之间的距离，以此保证第一像素驱动电路岛151和第二像素驱动电路152的边缘有足够的空间可以放置虚拟像素驱动电路14。
如图5所示，第一像素驱动电路岛151在第二方向靠近第二像素驱动电路岛152的一侧边缘设有一列第一虚拟像素驱动电路141，第n列第一像素驱动电路13为第一像素驱动电路岛151中最靠近第二像素驱动电路岛152的一列第一像素驱动电路，第n列第一像素驱动电路和相邻设置的一列第一虚拟像素驱动电路141分别与相邻设置的第n条数据线和第(n+1)条数据线电连接。如此，可以使得位于第一像素驱动电路岛151边缘的第n列第一像素驱动电路与第一像素驱动电路岛151中的其他列第一像素驱动电路13所处的电路环境相同，以此降低第n列第一像素驱动电路13控制的第一显示像素与其他列第一像素驱动电路13控制的第一显示像素之间的亮度差异。
第二像素驱动电路岛152在第二方向靠近第一像素驱动电路岛151的一侧边缘设有一列第二虚拟像素驱动电路142，第(n+1)列第一像素驱动电路13为第二像素驱动电路岛152中最靠近第一像素驱动电路岛151的一列第一像素驱动电路，第(n+1)列第一像素驱动电路13和相邻设置的一列第二虚拟像素驱动电路142分别与相邻设置的第(n+1)条数据线和第n条数据线电连接。
第二虚拟像素驱动电路岛152靠近透光显示区112的一侧边缘还设置有一列第三虚拟像素驱动电路142，第三虚拟像素驱动电路143设置于第(n+3)列第一像素驱动电路13与透光显示区之间。第(n+3)列第一像素驱动电路13与第(n+3)条数据线电连接，该列第三虚拟像素驱动电路143与第(n+4)条数据线电连接。如此可以使得位于第二像素驱动电路岛152边缘的第(n+1)列第一像素驱动电路13以及第(n+3)列第一像素驱动电路13与第二像素驱动电路岛152中其他列第一像素驱动电路13控制的第一显示单元的发光亮度的差异，从而改善功能附加区11内的显示亮度不均的问题。
本申请实施例的有益效果：本申请实施例提供一种显示面板及电子装置，所述电子装置包括所述显示面板，所述显示面板具有附加功能区，所述具有附加功能区包括过渡显示区和透光显示区，所述过渡显示区设置于所述透光显示区的外围，过渡显示区和透光显示区均设置有多个第一显示像素，过渡显示区设有多个第一像素驱动电路以及多个虚拟像素驱动电路，所述第一像素驱动电路与对应的至少一个所述第一显示像素电连接，多个第一像素驱动电路沿第一方向延伸设置成列，多列第一像素驱动电路沿第二方向排布设置，第一方向与第二方向不同，每列第一像素驱动电路中，至少部分第一像素驱动电路在第二方向至少一侧边的预设距离范围内，具有相邻设置的第一像素驱动电路或相邻设置的虚拟像素驱动电路，以此减小过渡显示区中靠近透光显示区的第一像素驱动电路所处的电路环境与第一子显示区中其他位置的第一像素驱动电路所处的电路环境差异，从而减少过渡显示区中靠近感光区的第一像素驱动电路控制的第一显示像素与其他第一像素驱动电路控制的第一显示像素的亮度差异，进而改善显示面板及电子装置在附加功能区存在的显示亮度不均的问题。
综上所述，虽然本申请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申请，本领域的普通技术人员，在不脱离本申请的精神和范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为基准。
