具体实施方式
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。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，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，都属于本公开保护的范围。
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。“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1A和图1B为两种针对异形显示区域的遮光层的设计方式。图1A为一种直线式遮光层结构设计方案中的局部显示面板示意图，如图1A所示，阴影区域为设置有遮光层15的非显示区域，空白区为包括多个阵列排布的像素单元10的显示区域，像素单元10包括红绿蓝(RGB)三个子像素11。遮光层15与显示区域之间的分界线12为锯齿形状，在显示区域边缘设计具有如图1A 所示的锯齿状边缘的遮光层15可以形成整体上呈现圆形或者多边形等非矩形形状的显示区域，例如，可以实现显示区域边缘为近似曲边的显示效果。
在研究中，本申请的发明人发现：采用图1A示出的设计方案设计的显示面板在显示时，使用者会明显看到显示图像在显示区域边缘呈现的锯齿形状，因而影响使用者的观看体验。
图1B为一种曲边式遮光层结构设计方案中的局部显示面板示意图，如图1B所示，以遮光层15的边缘根据实际显示区域需要的曲线边缘来设计为例进行描述，这里的遮光层15的曲线边缘设计可以避免出现图1A中显示区域边缘呈锯齿形状的情况的发生。
但是，本申请的发明人发现：由于图1B中的遮光层15的边缘没有沿着实际像素单元10的边缘，遮光层15对显示区域中的同一个像素单元10中的每个子像素11的遮光面积不相同，因而，显示区域边缘的像素单元10呈现在使用者眼中的色彩混色比例会受遮光层15的位置的影响。
如图1B所示，位于A区域的像素单元10中的红色(R)子像素11被遮光层15遮挡的面积大于绿色(G)子像素11和蓝色(B)子像素11被遮光层15遮挡的面积，因此，使用者观看到A区域呈现偏蓝色的显示图像；而位于B区域的像素单元10中的蓝色(B)子像素11被遮光层15遮挡的面积大于绿色(G)子像素11和红色(R)子像素11被遮光层15遮挡的面积，因此，使用者观看到B区域呈现偏红色的显示图像，因此，上述色偏问题的存在会影响到使用者的观看体验。
图1C为一种显示面板的整体平面结构示意图，图1D为图1C示出的显示面板中C区域的放大示意图。如图1C和1D所示，这里采用具有直线边缘的遮光层15的设计方案，即，遮光层15与显示区域边缘之间的边界为锯齿状，因此，图1C中的显示区域的边缘会看到细微的锯齿结构。显示区域的形状为近似圆形，当该显示面板在进行显示时，使用者会明显看到显示图像在显示区域边缘呈现的锯齿形状，因而影响使用者的观看体验。
本公开的实施例提供一种显示面板以及显示装置，该显示面板包括：沿行方向和列方向排布的多个像素单元，并且，显示区域的边缘包括沿行方向和列方向延伸的线段相连形成的折线，以相邻两个线段为邻边在显示区域内形成的平行四边形区域包括多行以及至少一列或者多列以及至少一行像素单元，并且，从相邻两个线段的相交点到相邻两个线段的除相交点之外的端点的方向分 别为第一方向和第二方向，在平行四边形区域中，沿第一方向和第二方向的至少之一排布的像素单元的开口率逐渐增大。本公开实施例提供的显示面板可以弱化显示区域边缘的锯齿形状，以使显示区域在进行显示时，显示区域的边缘几乎看不到锯齿形状，从而改善显示区域的视觉效果。
图2A为本公开一实施例提供的一种显示面板中显示区域边缘的局部平面示意图，如图2A所示，显示面板包括：沿行方向和列方向排布的多个像素单元110，这里的行方向即为与X方向平行的方向，列方向即为与Y方向平行的方向。显示面板包括显示区域100，显示区域100的边缘包括沿行方向和列方向延伸的线段101，102(沿行方向延伸的第一线段101以及沿列方向延伸的第二线段102)相连形成的折线，这里的显示区域100与被第一遮光层150遮住的非显示区域之间的分界线为由第一线段101以及第二线段102相连的折线，例如为图2A示出的锯齿状，因此显示区域100的边缘为由折线围成的锯齿形状。以相邻两个线段，即第一线段101和第二线段102为邻边在显示区域100内形成的平行四边形区域120包括多行以及至少一列或者多列以及至少一行像素单元110，图2A示出的示例为平行四边形区域120包括多行以及一列像素单元110的情况。从相邻两个线段101，102的相交点1011到相邻两个线段101，102的除相交点之外的端点(例如，第一线段101的端点1012以及第二线段102的端点1013)的方向分别为第一方向和第二方向。
例如，本实施例以从相交点1011到第一端点1012的方向(X方向的箭头所指的方向)为第一方向，从相交点1011到第二端点1013的方向(Y方向的箭头所指的方向)为第二方向为例进行说明。本实施例不限于此，第一方向与第二方向可以互换。在平行四边形区域120中，沿第一方向和第二方向的至少之一排布的像素单元110的开口率逐渐增大，以使得位于显示区域100边缘的平行四边形区域120在进行显示时其整体锯齿感弱化，即，显示区域100的边缘几乎看不到锯齿形状，从而改善显示区域100的视觉效果。
一般显示区域100在进行显示时，平行四边形区域120中像素单元110的行数或者列数越多，平行四边形区域120中的发光亮度越高，因此，使用者会明显感觉到显示区域100边缘的锯齿形状。由于平行四边形区域120中的两条邻边正好位于显示区域100的边缘折线(第一线段101和第二线段102)上，因此，显示区域100进行显示时，靠近这两条邻边的相交点1011的像素单元110的亮度越高，这两条邻边的夹角的形状就会被越清晰的显示出来以使使用 者明显感觉到锯齿形状。
在本公开的实施例的平行四边形区域120中，沿第一方向和第二方向的至少之一(图2A中仅为沿第二方向)排布的像素单元110的开口率逐渐增大，即，该平行四边形区域120中越靠近由显示区域100边缘折线中相邻两个折线的相交点1011的像素单元110的开口率越小。因此，在本实施例提供的显示区域进行显示时，通过对位于显示区域边缘的像素单元的开口率的调节以弱化显示区域边缘的锯齿形状，从而使显示区域边缘的锯齿几乎不能被肉眼识别。
例如，本实施例提供的显示区域100的形状包括非矩形形状。例如，显示区域100的形状可以包括近似圆形、近似多边形等异形形状，因此，本实施例提供的显示面板主要以异形显示面板为例。
例如，如图2A所示，行方向和列方向彼此垂直，即，显示区域100边缘的沿行方向和列方向延伸的相邻的两条线段，即第一线段101和第二线段102之间的夹角为直角，因此，以相邻两个线段为邻边在显示区域100内形成的平行四边形区域120为矩形区域。例如，本实施例中的行方向和列方向可以互换。
例如，如图2A所示，本实施例中的沿行方向和列方向延伸的线段相连形成的折线基本上也是沿着位于显示区域100边缘的像素单元110的边缘延伸的。例如，由于像素单元的边缘可能并非严格的直线段，因此，上述线段可以是基本上沿着像素单元的边缘。
例如，如图2A所示，本实施例中的像素单元110为双畴设计，本实施例包括但不限于此，例如，像素单元110也可为单畴设计。
例如，以图2A示出的平行四边形区域120中包括一列以及六行像素单元110为例进行描述，平行四边形区域120中的沿第二方向(Y方向)排布的相邻两行的像素单元110的开口率不相同。
例如，在平行四边形区域120中包括的像素单元110的行数较少时，相邻两行像素单元110的开口率可以不相同，以实现沿第二方向，像素单元110的开口率依次增大的变化趋势，从而可以较好的弱化显示区域100边缘的锯齿形状。
例如，在平行四边形区域120中，沿第一方向和第二方向的至少之一，任意相邻的两个像素单元110的开口率之差(透光面积之差)均相等，本实施例包括但不限于此。
例如，如图2A所示，在本实施例的一示例中的平行四边形区域120中， 沿第二方向，每个像素单元110的开口率逐渐增大可以包括：沿Y方向排布的第一行的像素单元110的开口面积为像素单元110总面积的1/6，第二行的像素单元110的开口面积为像素单元110总面积的2/6，第三行的像素单元110的开口面积为像素单元110总面积的2/6，第四行的像素单元110的开口面积为像素单元110总面积的3/6，第五行的像素单元110的开口面积为像素单元110总面积的4/6，第六行的像素单元110的开口面积为像素单元110总面积的5/6。本实施例不限于上述开口率的分布方式，只要在平行四边形区域120中，沿第二方向，每个像素单元110的开口率的变化趋势为逐渐增大即可。
例如，图2B为本公开的实施例的另一示例提供的显示面板中显示区域边缘的局部平面示意图，如图2B所示，平行四边形区域120中包括的像素单元110的行数较多时，可以相邻的两行或者三行的像素单元110的开口率相同，因此，平行四边形区域120中的像素单元110沿第二方向的开口率的整体变化趋势为逐渐增大。
例如，以图2B示出的平行四边形区域120中包括一列以及十行像素单元110为例进行描述，如图2B所示，沿第二方向，像素单元110的开口率逐渐增大可以包括：沿Y方向排布的第一行和第二行的像素单元110的开口面积为像素单元110总面积的1/6，第三行和第四行的像素单元110的开口面积为像素单元110总面积的2/6，第五行和第六行的像素单元110的开口面积为像素单元110总面积的3/6，第七行和第八行的像素单元110的开口面积为像素单元110总面积的4/6，第九行和第十行的像素单元110的开口面积为像素单元110总面积的5/6。本实施例不限于上述开口率的分布方式，需要根据平行四边形区域120中像素单元110的行数来划分每行像素单元110的开口率以及具有相同开口率的像素单元110的行数。
例如，图2C为本公开的实施例的一示例提供的显示面板中显示区域边缘的局部平面示意图，本示例中像素单元110的单畴设计仅是示意性的，可根据实际需要对像素单元110的具体结构进行设计。
例如，如图2C所示，每个像素单元110包括沿行方向(即平行于X方向)排布的多种颜色的子像素111。
例如，如图2C所示，本示例提供的像素单元110包括红绿蓝(RGB)三种颜色的子像素111，但不限于此。
例如，如图2C所示，在平行四边形区域120中，沿第一方向和第二方向 的至少之一，例如，本示例以沿第一方向(X方向)为例进行描述，具有相同颜色的子像素111的开口率逐渐增大。图2B中以平行四边形区域120中的不同颜色的子像素111上覆盖的遮挡层的填充图案不同以清楚表示对不同颜色的子像素111的遮挡。
例如，沿第一方向，蓝色(B)子像素111的开口率逐渐增大。
例如，沿第一方向，绿色(G)子像素111的开口率逐渐增大。
例如，沿第一方向，红色(R)子像素111的开口率逐渐增大。
在平行四边形区域中，沿第一方向和第二方向的至少之一，通过对具有相同颜色的子像素的开口率的控制，可以使得沿第一方向和第二方向的至少之一排列的像素单元的开口率逐渐增大，以降低平行四边形区域中的色偏。
图2D-图2F为本公开的实施例的另一示例提供的显示面板中显示区域边缘的局部平面示意图，例如，如图2D所示，在平行四边形区域120中，每个像素单元110中的各子像素111的开口率相同。
例如，以平行四边形区域120中的每个像素单元110包括红绿蓝(RGB)三种颜色的子像素为例进行示意，则每个像素单元110中的三种颜色的子像素111的开口率均相同，但本示例不限于此，例如，每个像素单元还可以包括两种颜色的子像素或者四种颜色的子像素。
一方面，由于本实施例中的第一遮挡层150的边缘基本上沿着像素单元110的边缘，因此，第一遮光层150对同一个像素单元110中每个子像素111的遮光面积相同；另一方面，由于每个像素单元110包括的子像素111的开口率相同，因此，显示区域100的边缘不会出现色偏，提高了显示面板的良率与显示质量。
例如，如图2D所示，本示例中的平行四边形区域120包括多行以及多列像素单元110，例如包括两行以及两列像素单元110。本示例中沿第二方向排列的像素单元110的开口率逐渐增大，而沿第一方向排列的像素单元110的开口率不变。
例如，如图2E所示，本示例中的平行四边形区域120包括多行以及多列像素单元110，例如包括两行以及两列像素单元110。本示例中沿第一方向排列的像素单元110的开口率逐渐增大，而沿第二方向排列的像素单元110的开口率不变。
例如，如图2F所示，本示例中的平行四边形区域120包括多行以及多列 像素单元110，例如包括两行以及两列像素单元110。本示例中沿第一方向以及第二方向排列的像素单元110的开口率都呈逐渐增大的趋势，即，沿相邻的两个线段101的相交点1011向平行四边形区域120的中心的方向，像素单元110的开口率呈逐渐增大的趋势。在平行四边形区域包括多行以及多列的情况下，沿第一方向以及第二方向排列的像素单元110的开口率都呈逐渐增大的趋势，可以使该区域在进行显示时，锯齿形状被更好的弱化，从而更好的改善显示区域的视觉效果。
例如，图2G为本公开的实施例的另一示例提供的显示面板中显示区域边缘的局部平面示意图，例如，如图2G所示，本示例提供的包括一行以及四列像素单元110的平行四边形区域120的边缘与显示区域100的边缘的重叠部分包括一个沿行方向延伸的第一线段101，以及两个沿列方向延伸的第二线段102。第二线段102的除与第一线段101的相交点1011之外的端点1013与其他的平行四边形区域中的沿行方向延伸的线段相连，即，第二线段102和与其相连的其他的位于显示区域边缘的线段不是处于同一直线上的。上述的行方向和列方向可以互换。
在平行四边形区域120中，从第一线段101与两个第二线段102的相交点1011到第一线段101的中点的方向(即沿X1方向和X2方向且到第一线段101的中点为截止点)，像素单元110的开口率逐渐增大，因而，在显示区域进行显示时，位于第一线段101与两个第二线段102的相交点1011处的锯齿均能够被弱化以使显示区域边缘的锯齿几乎不能被肉眼识别。
例如，本示例中从第一线段101与第二线段102的相交点1011到第一线段101的中点的方向，即，沿第一线段101的两个端点1011向中点的方向排列的像素单元110的开口率的变化趋势均为逐渐增大，但是，位于第一线段101的最靠近两个端点1011的两个像素单元110的开口率可以相同也可以不相同，并且像素单元110的开口率沿X1方向与沿X2方向的变化率也可以相同或者不同，并且位于最靠近第一线段101中点的两侧的两个像素单元110的开口率可以相同也可以不相同，本示例对此不作限制。
例如，在图2G所示的平行四边形区域120以包括偶数列或者偶数行为例进行描述，本实施例不限于此。
例如，平行四边形区域120中包括至少一行以及奇数列或者至少一列以及奇数行像素单元110的情况下，像素单元110的开口率的变化趋势与上述描述 相同，且位于第一线段101中点的像素单元110的开口率最大。例如，第一线段与第二线段也可以互换。
例如，如图2A所示，平行四边形区域120中的每个像素单元110中包括遮光结构130，沿第一方向和第二方向的至少之一排布的像素单元110中的遮光结构130的遮光面积逐渐减小，以使开口率逐渐增大。
例如，图2A所示的示例中，沿第二方向(Y方向)排布的像素单元110中的遮光结构130的遮光面积逐渐减小，以使沿第二方向排布的像素单元110中的开口率逐渐增大。
例如，如图2E所示的示例中，在平行四边形区域120中，沿第一方向(X方向)排布的像素单元110中的遮光结构130的遮光面积逐渐减小，以使沿第一方向排布的像素单元110中的开口率逐渐增大。
例如，如图2F所示的示例中，在平行四边形区域120中，沿第一方向以及第二方向排列的像素单元110的遮光结构130的遮光面积均呈逐渐减小的趋势，以使沿第一方向以及第二方向排布的像素单元110中的开口率都呈逐渐增大的趋势。
例如，如图2A所示，相邻的像素单元110(相邻的子像素111)之间设置有遮光层140，例如，相邻的像素单元110之间设置有黑矩阵。
例如，如图2A所示，相邻的像素单元110之间设置的遮光层140与显示区域100边缘以外的第一遮挡层150可以采用相同的材料和/或利用同一个掩模板在同一步图案化工艺中制作完成。
例如，相邻的像素单元110之间设置的遮光层140与显示区域100边缘以外的第一遮挡层150均为黑矩阵。
例如，如图2A所示，遮光结构130包括沿列方向延伸的至少一个子遮光结构131，子遮光结构131与遮光层140中包括的沿列方向延伸的子遮光层141的形状及尺寸相同。
例如，遮光层140包括设置在沿行方向排布的相邻的像素单元110(相邻的子像素111)之间的子遮光层141，子遮光结构131的材料与子遮光层141的材料可以均采用黑矩阵材料制作。
例如，子遮光结构131与子遮光层141可以通过同一个掩模板在同一步图案化工艺中制作完成，从而节省工艺步骤，本实施例包括但不限于此。
例如，如图2A所示，在平行四边形区域120中靠近相交点1011的像素单 元110中设置的遮光结构130包括沿列方向延伸的且沿行方向排布的多个子遮光结构131，沿行方向，该多个子遮光结构131连续设置，即相邻的子遮光结构131之间没有空隙。
例如，图3A为本公开实施例的一示例提供的遮光结构的示意图，如图3A所示，在平行四边形区域中的像素单元中设置的遮光结构130包括沿列方向延伸的间隔设置的多个子遮光结构131，即，相邻的子遮光结构131之间有空隙。本示例中可以通过调节子遮光结构的数量与宽度而精确调整每个像素单元的开口率。
例如，图3B为本公开实施例的另一示例提供的遮光结构的示意图，如图3B所示，在平行四边形区域中，遮光结构130包括沿行方向延伸的至少一个第一子遮光结构132，以及沿列方向延伸的至少一个第二子遮光结构133。
例如，如图3B所示，遮光结构130包括多个第一子遮光结构132，沿行方向，多个第一子遮光结构132既可以连续设置也可以间隔设置，本示例示出了多个第一子遮光结构132间隔设置的情况。此时，可以仅设置一个第二子遮光结构133，也可以设置多个第二子遮光结构133，本示例对此不作限制。
例如，如图3B所示，遮光结构130包括多个第二子遮光结构133，沿列方向，多个第二子遮光结构133既可以连续设置也可以间隔设置，本示例示出了多个第二子遮光结构133间隔设置的情况。此时，可以仅设置一个第一子遮光结构132，也可以设置多个第一子遮光结构132，本示例对此不作限制。
例如，如图3B所示，本示例示意性示出了遮光结构130包括多个第一子遮光结构132以及多个第二子遮光结构133，且多个第一子遮光结构132以及多个第二子遮光结构133均为间隔设置，本示例不限于此。
例如，在遮光结构130包括多个第一子遮光结构132以及多个第二子遮光结构133的情况下，多个第一子遮光结构132以及多个第二子遮光结构133均可以间隔设置或者连续设置。本示例中可以通过调节第一子遮光结构以及多个第二子遮光结构的数量与宽度而精确调整每个像素单元的开口率。
本公开另一实施例提供一种显示装置，包括上述实施例提供的任一种显示面板，采用该显示装置可以弱化显示区域边缘的锯齿形状，以使显示区域在进行显示时，显示区域边缘的视觉效果得到了改善。
例如，该显示装置可以为液晶显示装置、有机发光二极管(Organic Light-Emitting Diode，OLED)显示装置等显示器件以及包括该显示装置的电 视、数码相机、手机、手表、平板电脑、笔记本电脑、导航仪等任何具有显示功能的产品或者部件，本实施例不限于此。
