为使本公开实施例的目的、技术方案和优点更加清楚,下面将结合本公开实施例的附图,对本公开实施例的技术方案进行清楚、完整地描述。需要注意的是,附图中各图形的尺寸和形状不反映真实比例,目的只是示意说明本公开内容。并且自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。显然,所描述的实施例是本公开的部分而非全部实施例,基于所描述的本公开实施例,本领域普通技术人员在无需创造性劳动的前提下所获得的所有其它实施例,都属于本公开保护的范围。
除非另作定义,此处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。本公开说明书以及权利要求书中使用的“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。“内”、“外”、“上”、“下”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。
相关技术中的屏下摄像头技术,在摄像头(Camera)所在显示区仅保留发光器件,而发光器件对应的像素电路设置在Camera所在显示区外,并选用透明走线来实现Camera所在显示区外的像素电路和Camera所在显示区内发光器件的电气连接,以提升透光率、保证拍照效果。
受限于透明走线尺寸(Pitch)的工艺限制,目前多用三层或四层透明导电层(例如氧化铟锡,ITO)进行透明走线的布线。通常同层透明走线与至少一行或至少一列发光器件电连接,如图1至图3所示。其中,图1至图3中1、2、3表示三个不同的透明导电层,图1至图3中的方框表示发光器件的位置。
然而,由于不同透明导电层间制程工艺波动,会造成不同透明导电层的膜厚、线宽、线距等存在差异,故不同透明导电层中透明走线之间负载(Loading)及耦合电容不同,会造成显示不均。例如图1容易出现区域性条纹(Mura)、而图2容易出现竖条纹、而图3容易出现横条纹,极大影响了显示质量。
为了至少解决相关技术中存在的上述技术问题,本公开实施例提供了一种显示基板,如图4和图5所示,可以包括:
衬底基板101,该衬底基板101包括第一显示区AA1、以及至少位于第一显示区AA1一侧的第二显示区AA2;其中,第一显示区AA1的透光率大于第二显示区AA2的透光率;
发光器件层,位于衬底基板101之上,发光器件层包括位于第一显示区AA1的多个第一发光器件102;
驱动电路层,位于发光器件层与衬底基板101之间;驱动电路层包括多 个第一像素电路(图中未示出),多个第一像素电路在衬底基板101上的投影与第一显示区AA1没有重叠区域,多个第一像素电路与多个第一发光器件102电连接;
多个透明导电层,位于衬底基板101之上;每一透明导电层包括多条透明走线(图中未示出),多条透明走线连接于多个第一像素电路与多个第一发光器件102之间,同行第一发光器件102对应电连接的透明走线位于至少两个透明导电层,且同列第一发光器件102对应电连接的透明走线位于至少两个透明导电层。
在本公开实施例提供的上述显示基板中,通过设置同行第一发光器件102对应电连接的透明走线位于至少两个透明导电层,以及同列第一发光器件102对应电连接的透明走线位于至少两个透明导电层,使得各层透明走线的布线较均匀,从而降低了因不同透明导电层制程工艺或自身环境造成的Loading及耦合电容差异,改善了显示不均等不良。
在一些实施例中,多个第一像素电路可以位于第二显示区AA2,且多个透明导电层可以位于驱动电路层与发光器件层之间,以便于通过透明走线连接第一像素电路和第一发光器件102。另外,将多个第一像素电路设置于第二显示区AA2,利于提高屏占比,符合全面屏的发展趋势。
当然,在一些实施例中,多个第一像素电路还可以位于边框区,多个透明导电层的位置也不局限于驱动电路层与发光器件层之间,可根据需要灵活设置,在此不做具体限定。
在一些实施例中,如图5至图9所示,在第一方向Y上,任意相邻n个第一发光器件102对应电连接的透明走线异层设置,第一方向Y为行方向或列方向,n为透明导电层的总数。由图5至图9可以看出,各透明导电层电连接的发光器件102在第一方向Y上交替排布,使得多层透明走线在第一方向Y上均匀分布,有效解决了在第一方向Y所在行方向或列方向上的显示不均问题。
在一些实施例中,如图5至图9所示,每n排第一发光器件102为一组 在第一方向Y上周期排列;各透明导电层电连接的第一发光器件102,在一排第一发光器件102中的位置互补;同一透明导电层电连接的第一发光器件102,在一组第一发光器件102中的位置互补。这样设置,可以使得多层透明走线103在第一方向Y和第二方向X上分别均匀布线,有效解决了行方向和列方向上的显示不均问题。
在一些实施例中,如图5所示,在第二方向X上,任意相邻n个第一发光器件102对应电连接的透明走线103异层设置,第二方向X为行方向或列方向,且第二方向X与第一方向Y相互交叉。通过设计各透明导电层电连接的发光器件102在第二方向X上交替排布,使得多层透明走线在第二方向X上均匀分布,有效解决了在第二方向X所在行方向或列方向上的显示不均问题。
在一些实施例中,如图5所示,多个透明导电层可以包括层叠设置且相互绝缘层的第一透明导电层1、第二透明导电层2和第三透明导电层3;其中,第一透明导电层1包括多条第一透明走线,第二透明导电层2包括多条第二透明走线,第三透明导电层3包括多条第三透明走线;第一透明走线、第二透明走线、第三透明走线分别电连接的第一发光器件102在第一方向Y和第二方向X上均交替设置。由图5可以看出,第一透明导电层1、第二透明导电层2和第三透明导电层3在行方向和列方向上均做了交替的走线设计,可有效解决行方向和列方向的显示不均问题。
在一些实施例中,如图6和图8所示,在第二方向X上,任意相邻(n-1)个第一发光器件102对应电连接的透明走线异层设置;第二方向X为行方向或列方向,且第二方向X与第一方向Y相互交叉。这样可以使得各透明导电层在行方向、列方向和斜45°方向上的布线均为均匀设计,有效解决了行方向、列方向和斜45°方向上的显示不均问题,进一步提高了显示质量。
在一些实施例中,如图6和图8所示,多个透明导电层包括层叠设置且相互绝缘层的第一透明导电层1、第二透明导电层2和第三透明导电层3;其中,第一透明导电层1包括多条第一透明走线,第二透明导电层2包括多条 第二透明走线,第三透明导电层3包括多条第三透明走线;

第二透明走线与第1排第一发光器件中各重复单元的第2个第一发光器件、第4个第一发光器件、第9个第一发光器件,第2排第一发光器件中各重复单元的第1个第一发光器件、第6个第一发光器件、第8个第一发光器件,以及第3排第一发光器件中各重复单元的第3个第一发光器件、第5个第一发光器件、第7个第一发光器件电连接;
第三透明走线与第1排第一发光器件中各重复单元的第3个第一发光器件、第5个第一发光器件、第7个第一发光器件,第2排第一发光器件中各重复单元的第2个第一发光器件、第4个第一发光器件、第9个第一发光器件,以及第3排第一发光器件中各重复单元的第1个第一发光器件、第6个第一发光器件、第8个第一发光器件电连接。
在一些实施例中,如图7和图9所示,在第二方向X上,部分相邻(n-1)个第一发光器件对应电连接的透明走线异层设置、其余相邻(n-1)个第一发光器件对应电连接的透明走线同层设置;第二方向X为行方向或列方向,且 第二方向X与第一方向Y相互交叉。上述设置,可以使得各透明导电层在行方向、列方向和斜45°方向上的布线均为均匀设计,有效解决了行方向、列方向和斜45°方向上的显示不均问题,进一步提高了显示质量。
在一些实施例中,如图7和图9所示,多个透明导电层包括层叠设置且相互绝缘层的第一透明导电层1、第二透明导电层2和第三透明导电层3;其中,第一透明导电层1包括多条第一透明走线,第二透明导电层2包括多条第二透明走线,第三透明导电层3包括多条第三透明走线;
第一透明走线、第二透明走线、第三透明走线分别电连接的第一发光器件在第一方向Y上交替设置;
每9个第一发光器件为一重复单元在第二方向X上周期排列,在一重复单元中,位于最外侧的两个第一发光器件分别为第1个第一发光器件和第9个第一发光器件;
每3排第一发光器件为一组在第一方向Y上周期排列,在一组第一发光器件中,位于最外侧的两排第一发光器件分别为第1排第一发光器件和第3排第一发光器件;
第一透明走线与第1排第一发光器件中各重复单元的第1个第一发光器件、第5个第一发光器件、第9个第一发光器件,第2排第一发光器件中各重复单元的第3个第一发光器件、第4个第一发光器件、第8个第一发光器件,以及第3排第一发光器件中各重复单元的第2个第一发光器件、第6个第一发光器件、第7个第一发光器件电连接;
第二透明走线与第1排第一发光器件中各重复单元的第2个第一发光器件、第6个第一发光器件、第7个第一发光器件,第2排第一发光器件中各重复单元的第1个第一发光器件、第5个第一发光器件、第9个第一发光器件,以及第3排第一发光器件中各重复单元的第3个第一发光器件、第4个第一发光器件、第8个第一发光器件电连接;
第三透明走线与第1排第一发光器件中各重复单元的第3个第一发光器件、第4个第一发光器件、第8个第一发光器件,第2排第一发光器件中各 重复单元的第2个第一发光器件、第6个第一发光器件、第7个第一发光器件,以及第3排第一发光器件中各重复单元的第1个第一发光器件、第5个第一发光器件、第9个第一发光器件电连接。
由以上描述可以看出,在本公开实施例提供的上述显示基板中,多层透明走线只要交替电连接同行和同列的第一发光器件,即可有效解决显示不均的问题。并且,在第一发光器件的排布方式固定的情况下,多层透明走线与第一发光器件之间的电连接方式规律性越差,越利于提高显示均匀性。
在一些实施例中,为了尽可能减小透明走线的阻值,如图10至图13所示,可以将第一显示区AA1划分为第一子显示区AA11、第二子显示区AA12、第三子显示区AA13和第四子显示区AA14;其中,第一子显示区AA11与第二子显示区AA12在行方向上对称设置,第三子显示区AA13与第四子显示区AA14在行方向上对称设置,第一子显示区AA11与第三子显示区AA13在列方向上对称设置,第二子显示区AA12与第四子显示区AA14在列方向上对称设置;第一子显示区AA11的第一发光器件电连接的透明走线103向远离第二子显示区AA12的一侧延伸;第二子显示区AA12的第一发光器件电连接的透明走线103向远离第一子显示区AA11的一侧延伸;第三子显示区AA13的第一发光器件电连接的透明走线103向远离第四子显示区AA14的一侧延伸;第四子显示区AA14的第一发光器件电连接的透明走线103向远离第三子显示区AA13的一侧延伸。
需要说明的是,在具体实施时,第一子显示区AA11、第二子显示区AA12、第三子显示区AA13和第四子显示区AA14的位置不局限于上述对称关系,例如还可以采用分别沿行方向和列方向延伸的两条相交直线,将第一显示区AA1划分为四个非对称区域,分别作为第一子显示区AA11、第二子显示区AA12、第三子显示区AA13和第四子显示区AA14。在一些实施例中,第一子显示区AA11与第二子显示区AA12可以位于沿列方向延伸直线的两侧,第三子显示区AA13与第四子显示区AA14可以位于沿列方向延伸直线的两侧,第一子显示区AA11与第三子显示区AA13可以位于沿行方向延伸直线的两侧, 第二子显示区AA12与第四子显示区AA14可以位于沿行方向延伸直线的两侧,以利于透明走线的布线设计。
在一些实施例中,如图11至图13所示,各透明导电层中的透明走线103的数量可以相同,以利于第一发光器件102电连接的各层透明走线103均匀分布。
在一些实施例中,如图10至图13所示,每一透明导电层中的透明走线103互不交叠,不同透明导电层中的透明走线103在衬底基板101上的正投影可以互不交叠、也可以部分交叠或完全重合,在此不做限定。
在一些实施例中,驱动电路层还可以包括位于第二显示区AA2的多个第二像素电路,发光器件层还可以包括位于第二显示区AA2的多个第二发光器件,多个第二发光器件与多个第二像素电路电连接。如此,则可通过第二像素电路为第二发光器件提供驱动信号,从而实现第二显示区AA2的显示功能。
在一些实施例中,多个第二发光器件在第二显示区AA2的密度可以与多个第一发光器件102在第一显示区AA1的密度相同,从而保证第二显示区AA2的分辨率(PPI)与第一显示区AA1的分辨率相同,提高了整体显示效果。
在一些实施例中,第一发光器件102可以包括第一电极,第二发光器件可以包括第二电极,第一电极和第二电极同时为反射型阳极或反射型阴极;为了提高第一发光器件102所在第一显示区AA1的透光率,可以设计在第一发光器件102的发光颜色与第二发光器件的发光颜色相同时,第一电极在衬底基板上的正投影面积小于第二电极的正投影面积。
在一些实施例中,多个第二发光器件在第二显示区AA2的密度可以大于多个第一发光器件102在第一显示区AA1的密度,以提高第一显示区AA1的透光率。
在一些实施例中,第一发光器件102可以包括第一电极,第二发光器件可以包括第二电极,第一电极和第二电极同时为反射型阳极或反射型阴极;由于第一显示区AA1的分辨率小于第二显示区AA2的分辨率,即可提高第一 显示区AA1的透光率,因此无需减小第一电极的尺寸,基于此,第一发光器件的发光颜色与第二发光器件的发光颜色相同时,第一电极在衬底基板上的正投影面积可以等于第二电极的正投影面积。
在一些实施例中,如图4所示,第一显示区AA1被配置为安装取光模组,该取光模组可以为摄像头模组C等。
基于同一发明构思,本公开实施例还提供了一种显示面板,包括上述显示基板。该显示面板可以为有机电致发光显示面板(OLED)、量子点发光显示面板(QLED)、或微发光二极管显示面板(Micro LED)。由于该显示面板解决问题的原理与上述显示基板解决问题的原理相似,因此,本公开实施例提供的该显示面板的实施可以参见上述显示基板的实施,重复之处不再赘述。
基于同一发明构思,本公开实施例还提供了一种显示装置,包括:取光模组(例如摄像头模组),以及上述显示面板;其中,取光模组被设置在显示面板的第一显示区AA1。由于该显示装置解决问题的原理与上述显示基板解决问题的原理相似,因此,本公开实施例提供的该显示装置的实施可以参见上述显示基板的实施,重复之处不再赘述。
在一些实施例中,该显示装置可以为:手机、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪、智能手表、健身腕带、个人数字助理等任何具有显示功能的产品或部件。该显示装置包括但不限于:射频单元、网络模块、音频输出单元、输入单元、传感器、显示单元、用户输入单元、接口单元、存储器、处理器、以及电源等部件。本领域技术人员可以理解,上述显示装置的结构并不构成对显示装置的限定,显示装置可以包括上述更多或更少的部件,或者组合某些部件,或者不同的部件布置。
显然,本领域的技术人员可以对本发明实施例进行各种改动和变型而不脱离本发明实施例的精神和范围。这样,倘若本发明实施例的这些修改和变型属于本发明权利要求及其等同技术的范围之内,则本发明也意图包含这些改动和变型在内。
