附图说明
为了更清楚地说明本公开实施例的技术方案，下面将对实施例的附图作简单地介绍，显而易见地，下面描述中的附图仅仅涉及本公开的一些实施例，而非对本公开的限制。

图2A是一种显示基板的示意图；
图2B是另一种显示基板的示意图；

图4是本公开一个实施例提供的另一种显示基板的平面示意图；

具体实施方式
为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例的附图，对本发明实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本发明的一部分实施例，而不是全部的实施例。基于所描述的本发明的实施例，本领域普通技术人员在无需创造性劳动的前提下所获 得的所有其他实施例，都属于本发明保护的范围。
除非另外定义，本公开使用的技术术语或者科学术语应当为本发明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。同样，“一个”、“一”或者“该”等类似词语也不表示数量限制，而是表示存在至少一个。“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。“连接”或者“相连”等类似的词语并非限定于物理的或者机械的连接，而是可以包括电性的连接，不管是直接的还是间接的。“上”、“下”、“左”、“右”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。
图2A示出了一种显示基板500的示意图，该显示基板500可以作为例如可穿戴显示装置(例如，如图1所示的智能手表)的显示基板；如图1所示，该智能手表具有圆角矩形显示屏，与常规的矩形屏相比，其四个角为弧形，类似的平面可以被称为异形屏。其他类型的异形屏包括例如圆形屏等。为了实现异形屏的非规则边缘(例如，既不平行于显示面板列方向，也不平行于显示面板横向方向的边缘)，需要改变部分显示像素的布置方式或者可视部分的形状；例如，为了改变边缘位置的显示区域的可视部分的形状，例如可以改变黑矩阵的覆盖区域，以将黑矩阵延伸至原本用于显示发光的像素区域之中，从而例如可以使得矩形的显示像素的可视部分变为三角形。例如，该显示基板500可能存在边缘锯齿或/和边缘彩条问题。例如，如图2A所示，该显示基板500包括沿第一方向D1排布的多个像素组510。每个像素组510包括沿第一方向D1顺次排布的第一像素列511、第二像素列512和第三像素列513；第一像素列511包括沿与第一方向D1相交(例如垂直)的第二方向D2排布的多个第一显示像素5111；第二像素列512包括沿第二方向D2排布的多个第二显示像素5121；第三像素列513包括沿第二方向D2排布的多个第三显示像素5131。例如，如图2A所示，该显示基板500的显示区域的轮廓线520(也即，在显示区域的边界形成的轮廓线)包括锯齿形的轮廓线。发明人注意到，该锯齿形的轮廓线有可能致使显示基板500存在边缘锯齿的问题。此外，发明人还注意到，图2A示出的显示基板500存在连续缺失4 个同一显示像素的问题，并因此会导致边缘彩条问题。例如，在第一显示像素5111、第二显示像素5121和第三显示像素5131的颜色分别为红色、绿色和蓝色的情况下，区域530中分别连续缺失4个红色显示像素、2个绿色显示像素和0个蓝色显示像素，在此种情况下，将导致显示基板500存在蓝绿色的边缘彩条。
发明人又注意到，可以采用图2B示出的显示基板500降低边缘彩条问题，也即，使得显示区域中，每个像素组510中第一显示像素5111、第二显示像素5121和第三显示像素5131的个数相同，然而，发明人注意到图2B示出的显示基板500将导致边缘锯齿的问题进一步地恶化，由此降低了用户的使用体验。
本公开的实施例提供了一种显示基板、显示面板和显示装置，可以在缓解边缘锯齿问题的情况下缓解边缘彩条问题。
本公开的一个实施例提供了一种显示基板，该显示基板包括沿第一方向排布的多个像素组。每个像素组至少包括沿第一方向顺次排布的第一像素列和第二像素列；第一像素列包括一个第一显示像素或者沿与第一方向相交的第二方向排布的多个第一显示像素；第二像素列包括一个第二显示像素或者沿第二方向排布的多个第二显示像素；显示基板的显示区域的轮廓线包括与第二方向和第一方向均不平行的第一轮廓线。
例如，图3是本公开一个实施例提供的一种显示基板100的平面示意图，该显示基板100适用于形成具有例如圆形轮廓的显示面板和显示装置。例如，如图3所示，该显示基板100包括沿第一方向D1排布的多个像素组110。例如，每个像素组110至少包括沿第一方向D1顺次排布的第一像素列111和第二像素列112；第一像素列111包括一个第一显示像素1111或者沿与第一方向D1相交(例如，垂直)的第二方向D2排布的多个第一显示像素1111；第二像素列112包括一个第二显示像素1121或者沿第二方向D2排布的多个第二显示像素1121。例如，根据实际应用需求，每个像素组110还可以包括第三像素列113；第三像素列113可以包括一个第三显示像素1131或者可以包括沿第二方向D2排布的多个第三显示像素1131。例如，根据实际应用需求，每个像素组110还可以包括第四像素列、第五像素列(图中未示出)等，在此不再赘述。例如，根据实际应用需求，每个像素组110所包括的像素列 的个数可以均相等；例如，在每个像素组110所包括的像素列的个数为3个的情况下，每个像素组110可以仅包括沿第一方向D1顺次排布的第一像素列111、第二像素列112和第三像素列113。
例如，第一显示像素1111的颜色与第二显示像素1121的颜色不同。例如，在每个像素组110还包括第三像素列113的情况下，第三显示像素1131的颜色可以与第一显示像素1111的颜色以及第二显示像素1121的颜色均不同。例如，第一显示像素1111的颜色、第二显示像素1121的颜色和第三显示像素1131的颜色分别为红色、绿色和蓝色，但本公开的实施例不限于此；例如，第一显示像素1111的颜色、第二显示像素1121的颜色和第三显示像素1131的颜色还分别为蓝色、红色和绿色。例如，根据实际应用需求，第一显示像素1111的颜色、第二显示像素1121的颜色和第三显示像素1131的颜色还可以均相同(例如，均为蓝色)。
例如，显示基板100可以不发射光线，例如，显示基板可以实现为液晶显示面板的彩膜基板，在此种情况下，第一显示像素1111的颜色、第二显示像素1121的颜色和第三显示像素1131的颜色可以指第一显示像素1111、第二显示像素1121和第三显示像素1131的透射光线的颜色。又例如，根据实际应用需求，在显示基板100不发射光线的情况下，显示基板100还可以实现为液晶显示面板的阵列基板，在此种情况下，第一显示像素1111的颜色、第二显示像素1121的颜色和第三显示像素1131的颜色可以指阵列基板的第一显示像素1111、第二显示像素1121和第三显示像素1131所对应的彩膜基板的滤光片的透射光线的颜色。再例如，显示基板100还可以发射光线(例如，显示基板可以为有机发光二极管显示面板)，在此种情况下，第一显示像素1111的颜色、第二显示像素1121的颜色和第三显示像素1131的颜色可以指第一显示像素1111、第二显示像素1121和第三显示像素1131的发射光线的颜色。
例如，第一显示像素1111、第二显示像素1121和第三显示像素1131的形状可以为正方形或长方形，但本公开的实施例不限于此，例如，根据实际应用需求，第一显示像素1111、第二显示像素1121和第三显示像素1131的形状还可以为三角形或椭圆形。例如，在第一显示像素1111、第二显示像素1121和第三显示像素1131的形状均为长方形的情况下，第一显示像素1111、 第二显示像素1121和第三显示像素1131在第一方向D1上的尺寸与在第二方向D2上的尺寸可以为1:3，但本公开的实施例不限于此。
例如，如图5所示，该显示基板100可以包括显示区域161和周边区域162。例如，显示区域161可以位于显示基板100的中间区域，周边区域162可以为显示区域161之外、显示基板100的边界之内的区域。例如，显示基板100的显示区域161的轮廓线120形成在显示区域161和周边区域162相接的位置。例如，根据实际应用需求，该显示基板100还可以包括设置在多个像素组110的出光侧的遮光元件130，遮光元件130例如可以设置在显示基板100的周边区域162，由此可以使得周边区域162不出射光线，并由此可以形成显示基板100的显示区域161的轮廓线120。例如，遮光元件130可以遮挡经由显示像素出射的光线，例如，被遮光元件130遮挡的光线的强度与对应于入射到遮光元件130上的光线的强度的比值可以大于99.9％，但本公开的实施例不限于此。图5中位于边缘轮廓线的显示像素中用虚线示出的部分即为被遮光元件130遮挡的部分，而未被遮光元件130遮挡的部分构成该显示像素的可视部分。
需要说明的是，遮光元件130的大小和形状可以根据实际应用需求进行设定，本公开的实施例对此不做具体限定。例如，遮光元件130和显示区域161的形状可以互补，也即，遮光元件130和显示区域161的俯视图可以形成正方形或长方形。又例如，任一遮光元件(例如，图5中位于边缘轮廓线的显示像素中用虚线示出的部分)和与斜边1211相接的显示像素的形状可以互补，也即，任一遮光元件和与斜边1211相接的显示像素的俯视图可以形成正方形或长方形。
例如，如图6A和6B所示，根据实际应用需求，该显示基板100还可以包括设置于相邻的显示像素之间的黑矩阵140(例如，设置在第一显示像素1111和第二显示像素1121之间的黑矩阵140)，在此种情况下，遮光元件130可以与显示区域161中的黑矩阵140同层。需要说明的是，根据实际应用需求，黑矩阵140可以不仅仅设置于相邻的显示像素之间，黑矩阵140还可以延伸到相邻的显示像素的部分区域。
例如，图6A示出了一种液晶显示面板的剖面示意图。例如，如图6A所示，该液晶显示面板可以包括如图5所示的显示基板，并且图6A的至少部 分可通过沿图5所示的A-A’线剖切得到。例如，该液晶显示面板可以包括阵列基板153、液晶层152和对置基板151。例如，对置基板151可以包括第一滤光片1112、第二滤光片1122、第三滤光片1132、黑矩阵140和遮光元件130。例如，第一滤光片1112、第二滤光片1122和第三滤光片1132可以分别为红色、绿色和蓝色，但本公开的实施例不限于此。例如，如图6A所示，图5示出的显示基板100可以实现为对置基板151，在此种情况下，即使阵列基板153上的对应于周边区域的像素单元未被遮挡或者未被切割掉，由于在对置基板151设置了遮光元件，周边区域将依然没有光线出射，由此可以简化制作工艺。
例如，图6B是一种自发光显示面板的剖面示意图。例如，如图6B所示，该自发光显示面板可以包括如图5所示的显示基板，并且图6B的至少部分可通过沿图5所示的A-A’线剖切得到。例如，该自发光显示面板可以包括第一显示像素1111、第二显示像素1121、第三显示像素1131、黑矩阵140和遮光元件130。例如，第一显示像素1111、第二显示像素1121、第三显示像素1131可以发射光线，例如，第一显示像素1111、第二显示像素1121、第三显示像素1131可以分别发射红光、绿光和蓝光，但本公开的实施例不限于此。例如，如图6B所示，图5示出的显示基板100可以实现为图6B示出的自发光显示面板。
例如，如图3所示，该显示基板100还可以仅包括显示区域161。例如，可以在制作过程中仅制作对应于显示区域161的显示像素(例如，第一显示像素1111)。又例如，还可以在制作过程中同时制作对应于显示区域161的显示像素以及对应于周边区域162的显示像素，然后，沿显示区域161的轮廓线120切割基板，使得切割后的显示基板100仅包括显示区域161。例如，可以使用激光沿显示区域161的轮廓线120切割基板。
例如，如图3所示，显示基板100的显示区域161的轮廓线120可以包括与第二方向D2和第一方向D1均不平行的第一轮廓线121。例如，第一轮廓线121可以与对应的像素组110相交，并可以形成与第二方向D2和第一方向D1均不平行的斜边1211；例如，本公开的实施例的斜边1211可以是一条直线，为清楚起见，下面以斜边1211为直线为例对本公开做具体说明，但本公开的实施例不限于此，例如，根据实际应用需求，本公开的实施例的斜 边1211还可是弧形边。
例如，每个斜边1211的至少部分可以与对应的像素组110(也即，与该斜边1211相接的像素组110)中与斜边1211相接的第一显示像素1111和第二显示像素1121的中心的连线重合；例如，斜边1211的至少部分可以与位于相邻行和相邻列的第一显示像素1111和第二显示像素1121的中心的连线重合。例如，在第一显示像素1111和第二显示像素1121的形状为正方形或长方形的情况下，斜边1211的至少部分可以与对应的像素组110中与斜边1211相接的第一显示像素1111和第二显示像素1121的对角线重合，也即，该斜边1211(或第一轮廓线121)可以使得与该斜边1211相邻的第一显示像素1111和第二显示像素1121的形状由正方形或长方形变为直角三角形。
例如，如图3所示，在每个像素组110还包括第三像素列113的情况下，斜边1211的至少部分可以与对应的像素组110中与斜边1211相接的第一显示像素1111、第二显示像素1121和第三显示像素1131的中心的连线重合。例如，在第一显示像素1111、第二显示像素1121和第三显示像素1131的形状为正方形或长方形的情况下，斜边1211的至少部分可以与对应的像素组110中与斜边1211相接的第一显示像素1111、第二显示像素1121和第三显示像素1131的对角线重合，也即，该斜边1211(或第一轮廓线121)可以使得与该斜边1211相邻的第一显示像素1111、第二显示像素1121和第三显示像素1131的形状由正方形或长方形变为直角三角形。
例如，由于显示基板100的轮廓线120包括斜边1211，因此可以缓解形状为异形的显示基板100的边缘锯齿效应。又例如，在第一显示像素1111、第二显示像素1121和第三显示像素1131的颜色均不同的情况下，通过使得轮廓线120包括斜边1211还可以避免连续缺失多个(例如，4个)同一颜色的显示像素(例如，第一显示像素)，由此可以缓解显示基板100的边缘彩条问题。
例如，如图3所示，根据实际应用需求，显示基板100的显示区域161的轮廓线120还可以包括设置在相邻的斜边1211之间的、与第二方向D2平行的第二轮廓线122。例如，第二轮廓线122在第二方向D2上的尺寸等于第一显示像素1111在第二方向D2上的尺寸的整数倍(例如，1-5倍)，也即，使得相邻的斜边1211在第二方向上间隔N行(例如，1-5行)显示像素。例 如，如图3所示，通过在相邻的斜边1211之间设置与第二方向D2平行的第二轮廓线122，可以增加显示基板100边缘区域的第一显示像素1111的面积比例，也即，可以增加经由第一显示像素1111出射的光线的强度与经由第一显示像素1111、第二显示像素1121和第三显示像素1131出射的光线的强度总和的比值，由此可以进一步地缓解边缘彩条问题。此外，通过在相邻的斜边1211之间设置与第二方向D2平行的第二轮廓线122，还可以使得显示基板100的轮廓形状多样化。
例如，本公开的实施例的斜边1211和显示区域161的轮廓线120的形状不限于图3所示的形状。例如，根据实际应用需求，斜边1211和轮廓线120的形状还可以设置为图4所示的形式，在此种情况下，显示区域161的轮廓线120还可以包括设置于斜边1211和第二轮廓线122之间的、平行于第一方向D1的第三轮廓线123，由此可以使得显示基板100的轮廓形状更加多样化。
例如，本公开的实施例的斜边1211的设置方式不限于图3和图4所示的形状。例如，根据实际应用需求，斜边1211与第二方向D2的夹角可以为10°到80°，例如，斜边1211与第二方向D2的夹角可以为15°、30°、45°、60°、75°等。
例如，斜边1211与第二方向D2的夹角可以根据对应的显示区域161的轮廓线120的倾斜角度进行设置，例如，对于显示区域161的轮廓线120的相对第二方向D2的倾斜角度大的区域，斜边1211的倾斜角度相对于第二方向D2的倾斜角度可以比较大；而对于显示区域161的轮廓线120的相对于第二方向D2的倾斜角度小的区域，斜边1211的倾斜角度可以比较小。
例如，如图3所示，在显示区域161的轮廓线120包括多个斜边1211的情况下，多个斜边1211可以相互平行，例如，可以将多条斜边1211的倾斜角度均设置为45°、60°或30°，但本公开的实施例不限于此。例如，根据实际应用需求，也可以使得多个斜边1211设置不平行，也就是说，不同的斜边1211之间可以存在夹角。
例如，可以基于显示像素(例如，第一显示像素1111)的形状来设置斜边1211的形状。例如，对于正方形的显示像素，与斜边1211相接的显示像素可以沿着正方形的对角线切割形成；对于长方形形状的显示像素，与斜边1211相接的显示像素可以沿着长方形的对角线切割形成，此时可以降低轮廓 线120的形成难度。例如，本公开的实施例的斜边1211不限于沿对角线切割形成，斜边1211还可以沿实际应用需要的任意直线切割形成。又例如，斜边1211还可以通过使用遮光元件130遮挡周边区域162形成。再例如，斜边1211还可以在制作显示像素(第一显示像素1111)的过程中直接形成，例如，可以直接形成形状为直角三角形的显示像素。
本公开的至少一个实施例还提供了一种显示面板10，该显示面板10可以包括本公开的任一实施例提供的显示基板100。例如，该显示面板可以为液晶显示面板、有机发光二极管显示面板或发光二极管显示面板。本公开的至少一个实施例还提供了一种显示装置20，该显示装置可以包括本公开的任一实施例提供的显示基板100或者包括本公开的任一实施例提供的显示面板10。
需要说明的是，对于该显示面板10和显示装置20的其它必不可少的组成部分(例如薄膜晶体管控制装置、图像数据编码/解码装置、行扫描驱动器、列扫描驱动器、时钟电路等)可以采用适用的常规部件，这些是本领域的普通技术人员所应该理解的，在此不做赘述，也不应作为对本发明的限制。
本公开的实施例提供了一种显示基板、显示面板和显示装置，可以在缓解边缘锯齿问题的情况下缓解边缘彩条问题。
显然，本领域的技术人员可以对本公开的实施例进行各种改动、变型、组合而不脱离本公开的精神和范围。这样，倘若本公开的实施例的这些修改、变型、组合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。
以上所述仅是本发明的示范性实施方式，而非用于限制本发明的保护范围，本发明的保护范围由所附的权利要求确定。
