下面结合附图,对本公开实施例提供的显示基板及显示装置进行具体说明。
本公开实施例提供的一种显示基板,一般指的是OLED显示基板,如图1和图2所示,包括矩阵排列的多个像素P1或者P2、沿第一方向Y延伸且沿第二方向X排列的多条信号线;其中:
多条信号线包括多条数据线D_A、D_B和D_C和多条公共信号线(图1和图2中的V11);
每一像素P1或者P2包括至少三个不同颜色的子像素(图1和图2中以像素P1或者P2中包括A、B、C三个子像素为例进行示意),且像素P1或者P2中的每一子像素A、B、C分别对应连接一条数据线D_A、D_B和D_C;
以沿第二方向X排列的每相邻N个像素为一像素重复单元10,像素重复单元10中的N个像素共用一条公共信号线V11;N为大于1的整数;
对于沿第二方向X相邻设置的任意两个像素P1和P2,两个像素P1和P2中相同颜色的子像素的两侧的信号线呈对称设置。例如,像素P1中子像素 A两侧的信号线与像素P2中子像素A两侧的信号线呈对称设置,像素P1中子像素B两侧的信号线与像素P2中子像素B两侧的信号线呈对称设置,像素P1中子像素C两侧的信号线与像素P2中子像素C两侧的信号线呈对称设置。
本公开实施例提供的显示基板,每一像素包括至少三个不同颜色的子像素,且像素中的每一所述子像素分别对应连接一条所述数据线;以沿第二方向排列的每相邻N个像素为一像素重复单元,由于像素重复单元中的N个像素共用一条公共信号线;N为大于1的整数;因此可以减少整个显示面板中公共信号线的数量,从而有利于实现高PPI的显示面板。并且,对于沿第二方向相邻设置的任意两个像素,两个像素中相同颜色的子像素的两侧的信号线呈对称设置。这样可以保证相同颜色子像素周边信号线分布一致,即相同颜色子像素的版图布局一致,从而使相同颜色子像素受周边信号线的影响程度一致,进而保证同色子像素的发光均一性。
在具体实施时,子像素的出光主要由子像素的开口面积决定。因此,相关显示基板中相同颜色子像素的开口面积是相同的。但是通过研究发现,子像素周边的信号线的一致性(即版图布局的一致性)也会影响子像素的发光。这是因为,如果相同颜色的子像素的周边信号线分布不一致,能会影响发光层的出光角度,并且,信号线分布不一致,会导信号线上的阻抗不一致,从而影响发光电流。因此,本公开实施例中,通过使两个像素中相同颜色的子像素的两侧的信号线呈对称设置,使相同颜色子像素受周边信号线的影响程度一致,从而可以保证同色子像素的发光均一性。
可选地,在本公开实施例提供的显示基板中,如图1和图2所示,多条公共信号线V1包括多条第一公共电压线V11;
以沿第二方向X排列的每相邻两个像素P1和P2为一像素重复单元10,即N=2;
任一像素重复单元10中,两个像素P1和P2共用一条第一公共电压线V11,且共用的第一公共电压线V11位于两个像素P1和P2之间;
任一像素重复单元10中,两个像素P1和P2中的子像素A、B、C的排 列关于共用的第一公共电压线V11呈对称设置;
在沿所述第二方向相邻的任意两个所述像素中,与相同颜色的子像素A、B或C连接的数据线D_A、D_B和D_C呈对称设置。例如图1和图2中,与像素P1中的子像素A对应连接的数据线D_A和与像素P2中的子像素A对应连接的数据线D_A呈对称设置,与像素P1中的子像素B对应连接的数据线D_B和与像素P2中的子像素B对应连接的数据线D_B呈对称设置,与像素P1中的子像素C对应连接的数据线D_C和与像素P2中的子像素C对应连接的数据线D_C呈对称设置。从而实现相同颜色的子像素的两侧的信号线呈对称设置。
在具体实施时,在本公开实施例提供的显示基板中,对像素中子像素的排列顺序不作限定,例如图1所示,像素P1或P2中所有子像素A、B、C沿第二方向X排列设置,或者,像素中所有子像素沿第一方向排列设置,在此不作限定。
下面以像素中所有子像素沿第二方向排列设置为例,对本公开进行详细说明。需要说明的是,本实施例是为了更好的解释本公开,但不限制本公开。
可选地,在本公开实施例提供的显示基板中,如图1和2所示,与子像素A、B和C连接的数据线D_A、D_B和D_C与该子像素A、B、C相邻设置。即与子像素A连接的数据线D_A与该子像素A相邻设置,与子像素B连接的数据线D_B与该子像素B相邻设置,与子像素C连接的数据线D_C与该子像素C相邻设置,从而使子像素和与其连接的数据线的距离尽可能的近,便于数据线与子像素连接。
在具体实施时,公共信号线上的压降可能会影响对子像素的发光亮度,因此为了降低显示面板上公共信号线的压降,公共信号线的线宽大于数据线的线宽。
可选地,在本公开实施例提供的显示基板中,如图1和图2所示,对于与第一公共电压线V11相邻的子像素C,与子像素C连接的数据线D_C位于该子像素C远离第一公共电压线V11的一侧。避免将数据线D_C和第一公共 电压线V11设置在一起,从而使沿属于不同像素的相邻子像素之间的间隙较大,而同一像素中的相邻子像素之间的间隙较小。
可选地,在本公开实施例提供的显示基板中,如图3所示,多条公共信号线还包括多条第二公共电压线V12;
每一像素重复单元10的两侧分别设置有一条第二公共电压线V12,且沿第二方向X相邻的两个像素重复单元10之间仅设置有一条第二公共电压线V12;
位于该第二公共电压线V12两侧且均与该第二公共电压线V12相邻的两个像素共用该第二公共电压线V12。
这样,在本公开实施例提供的显示基板,相邻的像素共用第二公共电压线可以进一步提高显示面板PPI,第二公共电压线和第一公共电压线交替设置在相邻像素之间,保证相同颜色的子像素两侧的信号线布局一致。
可选地,在本公开实施例提供的显示基板中,对于与第二公共电压线V12相邻的子像素A,与子像素A连接的数据线D_A位于子像素远离第二公共电压线V12的一侧。避免将数据线D_A和第二公共电压线V12设置在一起,从而使沿属于不同像素的相邻子像素之间的间隙较大,而同一像素中的相邻子像素之间的间隙较小。
在具体实施时,在本公开实施例提供的显示基板中,公共信号线是指输入至每一子像素的信号是相同的信号线。例如电源电压线、参考信号线。因此,在具体实施时,第一公共电压线和第二公共电压线可以分别为电源电压线和参考信号线,在此不作限定。
需要说明的是,在本公开实施例中,仅是以两个像素共用其中一种公共信号线,或者共用两种公共信号线为例进行说明。对于两个像素共用三种公共信号线,或者更多种公共信号线的情况,实施原理与上述实施例相同,在此不作赘述。
在具体实施时,在显示基板中,一般相同颜色的子像素的开口形状是相同的。但是为了进一步提高相同颜色子像素的发光均一性,可选地,在本公 开实施例提供的显示基板中,如图4所示,在任一像素重复单元10中,相同颜色的子像素的开口形状关于共用的第一公共电压线V11呈对称设置。这样进一步的提高了相同颜色子像素与周边信号线的分布一致性。
在具体实施时,在本公开实施例提供的显示基板,同一像素中不同颜色的子像素的开口面积和开口形状可以相同,也可以不同,在此不作限定。
在具体实施时,在显示基板中,还包括与每一像素一一对应连接的像素驱动电路;每一像素驱动电路中一般包括多个晶体管和至少一个电容,本公开对像素驱动电路的具体结构不作限定。例如图5所示的像素驱动电路,包括晶体管T1~T3和电容C1,但不限于此。
可选地,在显示基板中,每一像素驱动电路的结构是相同的,即不同像素驱动电路中具有相同功能的晶体管的尺寸和膜层结构均是相同的,同样具有相同功能的电容的电容值大小和膜层结构也均是相同的。
可选地,在本公开实施例提供的显示基板中,在任一像素重复单元中,相同颜色的子像素对应连接的像素驱动电路关于共用的第一公共电压线呈对称设置。即像素驱动电路中具有相同功能的器件也是对称设置的,例如图6中,以子像素A为例,在任一像素重复单元中,相同颜色的子像素A对应连接的像素驱动电路关于共用的第一公共电压线V11呈对称设置。从而进一步保证相同颜色子像的版图布局一致,从而进一步保证相同颜色子像素的发光均一性。
在具体实施时,在本公开实施例提供的显示基板中,对像素中子像素的数量不作限定,例如像素中子像素的数量为3个、4或5个等,在此不作限定。目前,常见的显示基板中,像素中子像素的数量一般为3个或者4个。当像素中子像素的数量为3个时,3个子像素可以分别为红色子像素、蓝色子像素和绿色子像素。当像素中子像素的数量为4个时,4个子像素可以分别为红色子像素、蓝色子像素、绿色子像素和白色子像素。
可选地,在本公开实施例提供的显示基板中,如图1至图3所示,还包括:多条沿第二方向X延伸且沿第一方向Y排列扫描线G,每一像素的两侧 分别设置有至少一条扫描线G;位于每一像素的两侧的扫描线G的数量相同。从而使扫描线G对同色子像素的影响一致。
基于同一发明构思,本公开实施例还提供了一种显示装置,包括本公开实施例提供的上述任一种显示基板。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、导航仪等任何具有显示功能的产品或部件。该显示装置的实施可以参见上述显示基板的实施例,重复之处不再赘述。
本公开实施例提供的一种显示基板及显示装置,每一像素包括至少三个不同颜色的子像素,且像素中的每一所述子像素分别对应连接一条所述数据线;以沿第二方向排列的每相邻N个像素为一像素重复单元,由于像素重复单元中的N个像素共用一条公共信号线;N为大于1的整数;因此可以减少整个显示面板中公共信号线的数量,从而有利于实现高PPI的显示面板。并且,对于沿第二方向相邻设置的任意两个像素,两个像素中相同颜色的子像素的两侧的信号线呈对称设置。这样可以保证相同颜色子像素周边信号线分布一致,即相同颜色子像素的版图布局一致,从而使相同颜色子像素受周边信号线的影响程度一致,进而保证同色子像素的发光均一性。
显然,本领域的技术人员可以对本公开进行各种改动和变型而不脱离本公开的精神和范围。这样,倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内,则本公开也意图包含这些改动和变型在内。
