具体实施方式
为使本公开的上述目的、特征和优点能够更加明显易懂，下面将结合本公开的一些实施例中的附图，对本公开的一些实施例中的技术方案进行清楚、完整地描述。显然，所描述的实施例仅仅是本公开的一部分实施例， 而不是全部的实施例。
异形显示屏中的显示区域的边界包括曲线边界，在该曲线边界的相应位置处，异形显示屏中的多列(或多行)像素通常呈台阶状排布，也即在异形显示屏的曲线边界处，一像素列的靠近曲线边界的一端会比与其相邻的像素列的靠近曲线边界的一端多出或少出一定数目的像素，或者一像素行的靠近曲线边界的一端会比与其相邻的像素行的靠近曲线边界的一端多出或少出一定数目的像素，以使显示区域的曲线边界处在宏观上呈现曲线的视觉效果。
在相关技术中，靠近异形显示屏的曲线边界处的像素的子像素中通常会排布有除绿色子像素以外的其他颜色的子像素(如红色子像素或蓝色子像素等)。根据图12中所示的视见函数可知，在可见光谱中，人眼对于绿色子像素显示的绿色光的感知强度较强，对于除绿色子像素以外的其他颜色子像素显示的光的感知强度较弱，这样容易产生曲线边界处的显示感知不连续性，引起曲线边界处显示的锯齿感和颗粒感。
本公开的一些实施例提供了一种像素结构100，请参阅图1、图2以及图5，该像素结构100包括多个像素1所述多个像素1通常呈阵列状排布。所述多个像素1中的每个像素1包括至少一个绿色子像素101及至少一个其它颜色的子像素(例如：红色子像素102或蓝色子像素103)。所述多个像素1所确定的显示区域包括一主显示区域B及至少一个异形显示区域A，所述至少一个异形显示区域A的边界包括一条弧形边a，位于弧形边a相应位置处的每个像素1中，所述至少一个绿色子像素101位于所述至少一个其他颜色的子像素的靠近弧形边a的一侧。
在一些实施例中，请参阅图1，所述至少一个异形显示区域A中的每个异形显示区域A的边界还包括与弧形边a的一端连接的一条第一直边L 1以及和弧形边a的另一端连接的一条第二直边L 2，其中，第一直边L 1平行于所述多个像素1的行方向，第二直边L 2平行于所述多个像素1的列方向，且第一直边L 1的未与弧形边a连接的一端和第二直边L 2的未与弧形边a连接的一端相交呈直角。
本公开的一些实施例所提供的像素结构100中，上述异形显示区域A的形状与其边界的弧形边a的形状相关。
在一些示例中，请参阅图1，弧形边a朝向上述直角弯曲，也即弧形边a的曲率中心位于弧形边a的朝向直角的一侧，此时，异形显示区域A 的形状则为如第一异形显示区域A 1所示的形状。
在另一些示例中，请继续参阅图1，弧形边a背向上述直角弯曲，也即弧形边a的曲率中心位于弧形边a的背离直角的一侧，此时，异形显示区域A的形状则为如第二异形显示区域A 2所示的形状。此处，在异形显示区域A包括两个第二异型显示区域A 2，且该两个异形显示区域A 2相配合形成凹陷部C的情况下，可利用该凹陷部C集成设置终端的附属部件(例如手机的听筒、摄像头等)。
上述多个像素1中的部分像素1位于弧形边a相应位置处，表现为：该部分像素1与弧形边a相接近(如图2所示)；或者，该部分像素1与弧形边a相切(如图5所示)。
上述部分像素1的每个像素1中，所述至少一个绿色子像素101位于所述至少一个其它颜色的子像素的靠近弧形边a的一侧，也就是说，异形显示区域A中最靠近弧形边a的每个像素1中，所述至少一个绿色子像素101相对于所述至少一个其他颜色的子像素位于最靠近弧形边a的位置处。
本公开的一些实施例所提供的像素结构100中，将位于异形显示区域A的弧形边a相应位置处的每个像素1中的所述至少一个绿色子像素1设置在最靠近弧形边a的一侧，这样可以利用人眼对绿色光最敏感、感知强度最强的特点，提高人眼对于弧形边a处(即多个像素1所确定的显示区域的曲线边界)的子像素的感知强度，保证曲线边界处的子像素的显示亮度，提高曲线边界处的显示感知的连续性，减少曲线边界处显示的锯齿感和颗粒感，进而有利于提高异形显示屏的显示效果。
在本公开的一些实施例中，如图1所示，位于异形显示区域A内的每个子像素的有效显示面积与位于主显示区域B内的相应颜色的每个子像素的有效显示面积相等。这样能够避免由于位于显示区域的曲线边界处的各子像素的有效显示面积与主显示区域的对应像素的有效显示面积不一致而带来的色偏问题，可以有效提高异形显示屏的显示效果。
此处，上述“有效显示面积”是指在每个子像素中实际用于显示的面积。例如，在OLED(Organic Light-Emitting Diode，有机发光二极管)显示面板中，“有效显示面积”指是的每个子像素中的发光面积；在液晶显示面板中，“有效显示面积”指的是每个子像素中的透光面积。
上述像素结构100中，位于异形显示区域A的相邻像素行或相邻像素列，在靠近弧形边a相应位置处的一端具有像素1个数的差异，该差异的 数值跟每一像素行或像素列中位于弧形边a对应位置处的像素1的中心与D 0点之间的连线和第二直边L 2之间的夹角相关。
下面以第一异形显示区域A 1为例，对其中的相邻像素行或相邻像素列在靠近弧形边a相应位置处的一端的像素1个数差异进行示意性描述。
请参阅图2～图4，记第一异形显示区域A 1的第一直边L 1和第二直边L 2的交点为D 0，第一直边L 1与第二直边L 2相交所呈的直角的角平分线L 0与弧形边a的交点为D 1，D 1点将弧形边a分成第一弧段a 1和第二弧段a 2。
请参阅图3，称第一弧段a 1与第一直边L 1的交点为D 2，过交点D 1且平行于多个像素1的列方向的直线与第一直边L 1的交点为D 3，在由交点D 2指向交点D 3的方向上，第一弧段a 1对应N列像素，N≥2，且N为正整数，第j列像素1中位于弧形边a对应位置处的像素1的中心O与D 0点之间的连线L＇，与第二直边L 2之间的夹角为α j，j为1至N之间的任一整数，此处，45°≤α j≤90°。第j列像素1靠近第一弧段a 1的一端与第j-1列像素1靠近第一弧段a 1的一端的像素1的个数差异值(也即第j列像素1靠近第一弧段a 1的一端超出第j-1列像素1靠近第一弧段a 1的一端的像素1的个数)等于tanα j的值取整数的值。也就是说，在交点D 2指向交点D 3的方向上，第一弧段a 1所对应的各列像素1中，后一列像素1靠近第一弧段a 1的一端超出前一列像素1靠近第一弧段a 1的一端的像素10的个数可根据tanα j的取整数的值来设置。
在上述像素结构100中，将每个像素1近似看作正方形，假设每个像素1的边长为d，第j列像素1比第j-1列像素1靠近第一弧段a 1的一端超出的长度为h，分别以d和h作为两条直角边确定出直角三角形S 1，直角三角形S 1的斜边c与直角边d的夹角设为α。第j列像素1中处于弧形边a(第一弧段a 1)相应位置处的像素1的中心O与D 0点之间的连线与第一弧段a 1的交点处的切线的斜率，与直角三角形S 1的斜边c的斜率近似相等，因此可以将角α与角α j看作近似相等，则由上述几何关系可以得到等式：tanα j＝tanα＝h/d。因为d对应一个像素1，h对应所第j列像素1比第j-1列像素1靠近第一弧段a 1的一端超出的像素1的个数，则tanα j的值h/d取整数后的值可为第j列像素1比第j-1列像素1靠近第一弧段a 1的一端的像素1的超出个数。
此处，tanα j的值取整数依据四舍五入原则。示例性的，α j＝85°，tanα j＝11.43，tanα j取整数的值为11，则在α j为85°的情况下所对应的像素 列相对于其前一列像素在靠近第一弧段a 1的一端需要超出11个像素1。示例性的，α j＝50°，tanα j＝1.19，tanα j取整数的值为1，则在α j为50°的情况下所对应的像素列相对于其前一列像素在靠近第一弧段a 1的一端需要超出1个像素1。
需要说明的是，α j在45°～90°之间依次递减的过程中，靠近第一弧段a 1的一端具有像素1个数差异的像素列的列数逐渐增加，α j在45°～90°之间依次递增的过程中，靠近第一弧段a 1的一端具有像素1个数差异的像素列的列数逐渐递减；相邻像素列的靠近第一弧段a 1的一端的像素1的个数差异值也会逐渐产生相应的变化。
通过上述设置方式来对显示区域的曲线边界处呈台阶状排布的像素1的个数进行设置，能够提高上述像素结构100在曲线边界处的像素排布的平滑性，降低曲线边界处在视觉上的锯齿感和颗粒感，从而可以提高异形显示屏的视觉效果。
请参阅图4，称第二弧段a 2与第二直边L 2的交点为D 4，过交点D 1且平行于多个像素1的行方向的直线与第二直边L 2的交点为D 5，在由交点D 4指向交点D 5的方向上，第二弧段a 2依次对应M行像素1，M≥2，且M为正整数，第i行像素1中处于弧形边a对应位置处的像素1的中心O与D 0点之间的连线L＇，与第二直边L 2之间的夹角为α i，i为1至M之间的任一整数，此处0°≤α i＜45°。第i行像素1靠近第二弧段a 2的一端与第i-1行像素1靠近第二弧段a 2的一端的像素1的个数差异值(也即第i行像素1靠近第二弧段a 2的一端超出第i-1行像素1靠近第二弧段a 2的一端的像素1的个数)等于tanα i的值的倒数取整数的值。也就是说，在交点D 4指向交点D 5的方向上，第二弧段a 2所对应的各行像素1中，后一行像素1靠近第一弧段a 1的一端超出前一行像素1靠近第二弧段a 2的一端的像素1的个数可根据tanα j的值的倒数的整数值来设置。
在上述像素结构100中，将每个像素1近似看作正方形，假设每个像素1的边长为d，第i行像素1比第i-1行像素1靠近第二弧段a 2的一端超出的长度为h，分别以d和h作为两条直角边确定出直角三角形S 2，直角三角形S 2的斜边c与直角边h的夹角设为β。第i行像素1中处于弧形边a(第二弧段a 2)相应位置处的像素1的中心O与D 0点之间的连线与第二弧段a 2的交点处的切线的斜率，与直角三角形S 2的斜边c的斜率近似相等，因此可以将角β与角α i看作近似相等，则由上述几何关系可以得到等式： tanα i＝tanβ＝d/h。因为d对应一个像素1，h对应第i行像素1比第i-1行像素1靠近第二弧段a 2的一端超出的像素1的个数，则tanα i的值的倒数h/d取整数后的值可为第i行像素1比第i-1行像素1靠近第二弧段a 2的一端的像素1的超出个数。
此处，tanα i的值取整数依据四舍五入原则。示例性的，α i＝25°，tanα i的倒数为2.14，tanα i的倒数取整数的值为2，则在α i为25°的情况下所对应的像素行相对于其前一行像素在靠近第二弧段a 2的一端需要超出2个像素1。示例性的，α i＝10°，tanα i的倒数为5.67，tanα i的倒数取整数的值为6，则在α i为10°的情况下所对应的像素行相对于其前一行像素在靠近第二弧段a 2的一端需要超出6个像素1。
需要说明的是，α j在0°～45°之间依次递减(或依次递增)的过程中，靠近第二弧段a 2的一端具有像素1个数差异的像素行的行数逐渐递减(或逐渐增加)，相邻像素行的靠近第二弧段a 2的一端的像素1的个数差异值也会逐渐产生相应的变化。
通过上述设置方式来对显示区域的曲线边界处呈台阶状排布的像素1的个数进行设置，能够提高上述像素结构100在曲线边界处的平滑性，降低曲线边界处视觉上的锯齿感和颗粒感，从而能够提高异形显示屏的视觉效果。
在本公开的一些实施例中，上述像素结构100中，位于弧形边a相应位置处的每个像素1中的子像素的结构包括多种，该结构根据实际需要选择设置，本公开的一些实施例对此不做限定。
在一些示例中，请参阅图6，位于弧形边a相应位置处的每个像素1中，所述至少一个绿色子像素101的靠近弧形边a的一侧具有第一斜边d 1，该第一斜边d 1与弧形边a的相应位置处的切线之间呈夹角设置。示例性的，第一斜边d1与弧形边a的相应位置处的切线之间的夹角的取值范围为0°～45°。也即，第一斜边d1与弧形边a的相应位置处的切线之间平行或趋近于平行。这样可以减弱弧形边a处因相邻像素行或相邻像素列之间的像素1数目差异导致的视觉上的突出感，使显示区域的曲线边界处的显示在宏观上更加平滑，降低曲线边界处视觉上的锯齿感和颗粒感，提高异形显示屏的视觉效果。
此处，所述至少一个绿色子像素101的形状包括多种。示例性的，所述至少一个绿色子像素101的形状包括如图6所示的三角形，或者包括五 边形(例如由矩形的一个顶角缺角而形成的五边形)，或者包括梯形或菱形等。
在另一些示例中，请参阅图7，位于弧形边a相应位置处的每个像素1中，所述至少一个其它颜色的子像素(例如红色子像素102或蓝色子像素103)的靠近弧形边a的一侧具有第二斜边d2，该第二斜边d2与弧形边a的相应位置处的切线之间呈夹角设置。示例性的，第二斜边d2与弧形边a的相应位置处的切线之间的夹角取值范围为0°～45°。也即，第二斜边d2与弧形边a的相应位置处的切线之间平行或趋近于平行。这样可以进一步减弱弧形边a处因相邻像素行或相邻像素列之间的像素1数目差异导致的视觉上的突出感，使显示区域的曲线边界在宏观上更加的平滑，进一步降低曲线边界处视觉上的锯齿感和颗粒感，提高异形显示屏的视觉效果。
此处，所述至少一个其他颜色的子像素的形状包括多种。示例性的，所述至少一个其它颜色的子像素的形状包括三角形，或者包括五边形(例如由矩形的一个顶角缺角而形成的五边形)，或者包括梯形或菱形等。
本公开的一些实施例所提供的像素结构100中，其所包括的多个像素1有多种设计方式，该多种设计方式与每个像素1的结构相关。
在一些实施性中，像素结构100所包括的多个像素1中，包括多个第一像素11和多个第二像素12，所述多个第一像素11中的每个第一像素11包括至少一个绿色子像素101和一个红色子像素102，所述多个第二像素12中的每个第二像素12包括至少一个绿色子像素101和一个蓝色子像素103。
此处，多个像素1的设计方式有多种。请参阅图2、图8和图9，以下对多个像素1的多种设计方式进行示意性说明。
在一些示例中，请参阅图2，在多个像素1的行方向上，由多个第一像素11排列而成的第一像素行与由多个第二像素12排列而成的第二像素行交替排布。在多个像素1的列方向上，同一列的多个像素1中，第一像素11与第二像素12交替排布，且各第一像素11中的所述至少一个绿色子像素101和各第二像素12中的所述至少一个绿色子像素101排成一列，各第一像素11中的红色子像素102和各第二像素12中的蓝色子像素103排成一列。
在另一些示例中，在多个像素1的行方向上，同一行的多个像素1中，第一像素11与第二像素12交替排布。此时，在多个像素1的列方向上， 多个像素1有多种设计方式。
示例性的，请参阅图8，在多个像素1的列方向上，同一列的多个像素1中，第一像素11与第二像素12交替排布，各第一像素11中的所述至少一个绿色子像素101和各第二像素12中的所述至少一个绿色子像素101排成一列，各第一像素11中的红色子像素102和各第二像素12中的蓝色子像素103排成一列，这样可以有效减弱色偏。
示例性的，请参阅图9，在多个像素1的列方向上，由多个第一像素11排列而成的第一像素列与由多个第二像素12排列而成的第二像素列交替排布，且第一像素列的各第一像素11中的所述至少一个绿色子像素101排成一列，红色子像素102排成一列，第二像素列的各第二像素12中的所述至少一个绿色子像素101排成一列，蓝色子像素103排成一列。
