具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请具体实施例及相应的附图对本申请技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。

请参见图1，为本申请的一个实施例提供的异形显示屏的局部微观结构。
异形显示屏具有轮廓线101以界定有效显示区的范围。有效显示区可以用于呈现图片或动态显示画面。当有效显示区设置有触控传感器的时候，还可以感应操作者的动作，并做出响应。在具体应用中，异形显示屏可以是电视的曲面屏，或者是手机的曲面屏。
异形显示屏包括重复排列的若干第一发光单元102和重复排列的若干第二发光单元103。
其中，第一发光单元102包含的子像素的数量多于第二发光单元103包含的子像素数量。
所述第一发光单元连续排布并在所述有效显示区形成主显示区。
至少一个所述第二发光单元孤立分布并在所述有效显示区形成边缘显示区。
所述第一发光单元102包含至少一个像素单元。所述第二发光单元103包含至少一个子像素。
下面以第一发光单元102包含两个像素单元，第二发光单元103包括一个像素单元为例进行具体描述，其中一个像素单元包含一个红色子像素、一个绿色子像素和一个蓝色子像素。如图1所示，第一发光单元102包括两个第一子像素、两个第二子像素和两个第三子像素。
第一子像素、第二子像素、第三子像素可以各自发出不同颜色的光。第一子像素、第二子像素、第三子像素可以发出红色(R)、绿色(G)、蓝色(B)这三种颜色的光中的任意一种，但是第一子像素、第二子像素、第三子像素不能发出同一种颜色的光。第一发光单元102显示的颜色取决于其包含的第一子 像素、第二子像素、第三子像素的种类。
结构上，三种子像素两两排布可构成六种不同形式的第一发光单元102。在本实施例中，可以选取其中一种，在本申请中选择的第一发光单元102的像素排布方式为B-R/R-G/G-B。横向(图1中的左右方向)上，第一排蓝色子像素的中心与红色子像素的中心的连线相对于水平线倾斜。第二排红色子像素的中心与绿色子像素的中心的连线平行于第一排蓝色子像素的中心与红色子像素的中心的连线，第三排绿色子像素的中心与蓝色子像素的中心的连线平行于第一排蓝色子像素的中心与红色子像素的中心的连线。纵向(图1中的上下方向)上，第一列B-R-G子像素的中心位于同一直线上，第二列R-G-B子像素的中心也位于同一直线。采用此种结构的第一发光单元102的形状容易拟合异形显示屏轮廓线101的形状。
第一发光单元102的子像素还可采取其他排布方式，如两个第一子像素、两个第二子像素和两个第三子像素以两行三列或三行两列的方式排布等。第一发光单元102中的子像素的排布方式并不限于以上几种，只要满足显示屏的色彩显示需求即可。第二发光单元103包括一个第一子像素、一个第二子像素和一个第三子像素。
第一子像素、第二子像素、第三子像素同样可以发出不同颜色的光，例如可以分别发出红色(R)、绿色(G)、蓝色(B)三色。三个子像素发出的光的颜色互不相同。由这三个子像素构成的第二发光单元103的显色原理与第一发光单元102相同，在此不再赘述。
结构上，归属于第二发光单元103的一个第一子像素、一个第二子像素和一个第三子像素呈三角形排布。第二发光单元103与第一发光单元102相互结合可以拟合异形显示屏的轮廓线101。
归属于第二发光单元103的第一子像素、第二子像素、第三子像素还可采取其他排布方式，如第一子像素、第二子像素、第三子像素的中心位于同一直线上，前述子像素的排列顺序并不限于以上几种，只要满足显示屏的色彩显示需求即可。
如图3所示，第一发光单元102由标准RGB排列的两个像素单元构成。具体的，在图3中第一行为由红色(R)子像素、绿色(G)子像素、蓝色(B)子像素构成的一个像素单元，第二行同样为由红色(R)子像素、绿色(G)子像素、蓝色(B)子像素构成的一个像素单元，两个像素单元在列的方向(图3中的上下方向)上堆叠设置。当沿列的方向看时，红色(R)子像素构成一列，绿色(G)子像素构成一列，蓝色(B)子像素构成一列。应当指出的是，可以将这里的列改变成行。
第二发光单元103为成行排列的红色(R)子像素、绿色(G)子像素、蓝色(B)子像素。也就是说，第一子像素为红色(R)子像素，第二子像素为绿色(G)子像素，第三子像素为蓝色(B)子像素。当然这里的第一子像素、第二子像素和第三像素的排列顺序可以根据具体情形进行调整。
可以理解的是，第二发光单元103的子像素可以为其他数量，只要保证第二发光单元103的子像素数量少于第一发光单元102的子像素数量即能满足本申请的目的。具体的，当第一发光单元102包括两个第一子像素、两个第二子像素和两个第三子像素时，第二发光单元可以为两个第一子像素、两个第二子像素、一个第三子像素，或者可以为两个第一子像素、一个第二子像素、一个第三子像素，或者可以为一个第一子像素、一个第二子像素、一个第三子像素，或者可以为一个第一子像素、一个第二子像素、一个第三子像素中的任意两个子像素，或者可以为一个第一子像素、一个第二子像素和一个第三子像素中的 任意一个子像素。
对应的，当第一发光单元102包括的子像素数量减少时，第二发光单元103包括的数量可以相应减少。例如，第一发光单元102可以包括以下之一：
两个第一子像素、两个第二子像素、一个第三子像素；
两个第一子像素、一个第二子像素、一个第三子像素；
一个第一子像素、一个第二子像素、一个第三子像素。
应当重点指出的是，这里的第一子像素为红色(R)子像素，第二子像素为绿色(G)子像素，第三子像素为蓝色(B)子像素，然而这仅是一种举例，第一子像素、第二子像素、第三子像素中的至少一者可以为红、绿、蓝三原色之外的其他颜色。
根据本申请的另一个实施例提供的异形显示屏，所述异形显示屏具有轮廓线以界定有效显示区的范围。
所述异形显示屏包括重复排列的若干第一发光单元和重复排列的若干第二发光单元。
其中，所述第一发光单元所在表面的曲率半径大于所述第二发光单元所在表面的曲率半径。
所述第一发光单元连续排布并在所述有效显示区形成主显示区。
至少一个所述第二发光单元孤立分布并在所述有效显示区形成边缘显示区。
由于所述主显示区的第一发光单元所在表面的曲率半径大于所述边缘显示区的第二发光单元所在表面的曲率半径，使得边缘显示区的发光亮度低于主显示区的发光亮度，从而，降低了边缘显示区在微观尺度观察时，呈现明显的锯齿感或颗粒感，以提高异形显示屏的显示品质。
进一步的，在本申请提供的实施例中，第一发光单元102规则地重复排列在有效显示区内并构成主显示区104。第二发光单元103孤立分布并在有效显示区内形成边缘显示区105。
边缘显示区105的第二发光单元103满足如下条件：从第二发光单元103的中心到轮廓线101的法向距离不超过预设距离阈值。可以根据统计数据设定预设距离阈值，以确定一个发光单元是否位于边缘显示区105。例如，根据统计数据发现，对于特定尺寸的发光单元，如果从轮廓线101向内偏移3mm会到达主显示区104，则可以设定该3mm为预设距离阈值。当然，这里的预设距离阈值为3mm仅是一种举例，具体的预设距离阈值的范围与轮廓线101的曲率和发光单元的尺寸有关。
第二发光单元103中包含的子像素的数量少于第一发光单元102中包含的子像素的数量，故第二发光单元103的发光面积小于第一发光单元102的发光面积。由于第二发光单元103位于靠近异形显示屏轮廓线101的边缘显示区105，并且具有不同外形的第一发光单元102和第二发光单元103以拟合异形显示屏的轮廓线101的方式相互结合排列，所以可以降低在微观尺寸观察时显示的锯齿感。
应当指出的是，第一发光单元中包含的子像素的数量多于第二发光单元中包含的子像素数量。这里的第一发光单元102为两个红色(R)子像素、两个绿色(G)子像素、两个蓝色(B)子像素。可以理解的是，这里的第一发光单元102还可以具有某个子像素被共用的情形，只要满足第一发光单元中包含的子像素的数量多于第二发光单元中包含的子像素数量即可。例如，第一发光单元102包括一个红色(R)子像素、两个绿色(G)子像素和两个蓝色(B)子像素，其中红色(R)子像素被共用。还可以是第一发光单元102包括一个红色(R) 子像素、一个绿色(G)子像素和两个蓝色(B)子像素，其中红色(R)子像素和绿色(G)子像素被共用。
请参见图2，为本申请的实施例提供另一种异形显示屏的局部微观结构。
该异形显示屏具有轮廓线201以界定有效显示区的范围。有效显示区的作用与参见图1所述的实施例中的相似，在此不再赘述。
异形显示屏包括重复排列的若干第一发光单元202和重复排列的若干第二发光单元203。
其中，所述第一发光单元中包含的子像素的数量等于所述第二发光单元中包含的子像素数量。
在第一方向(图2中的左右方向)上，所述第一发光单元和所述第二发光单元分别连续排布。
在第二方向(图2中的上下方向)上，所述第一发光单元和所述第二发光单元交替排布。
第一发光单元202包括一个第一子像素、一个第二子像素和一个第三子像素。三种子像素可以各自发出不同颜色的光。在本实施例中，三个子像素发出的光的颜色可以分别为红色(R)、绿色(G)、蓝色(B)。
归属于第一发光单元202的三个子像素呈三角形排列，当三个子像素均匀等量发光时，第一发光单元202达到白平衡。
进一步的，在本申请提供的又一实施例中，所述三角形为锐角三角形或直角三角形。
对于锐角三角形，相邻两行或两列的子像素之间的距离为半个子像素的尺寸，这样可以最大程度的近似于异形显示屏的轮廓线，从而，降低异形显示屏的锯齿感和颗粒感。
对于直角三角形，在堆叠子像素时，可以借助直角边堆叠子像素，从而提供便利性。
进一步的，所述第一子像素、所述第二子像素和所述第三子像素中的一者的发光面积与另外两者的发光面积不同，例如，假设第一子像素为红色子像素，第二子像素为绿色子像素，第三子像素为蓝色子像素，因为蓝光材料的发光效率低，所以可以将第三子像素的发光面积设置为大于第一子像素或第二子像素的发光面积。当然这只是举例，还可以有其他的发光面积关系。
第一发光单元202的结构不限于此，也可以为三个子像素的中心位于同一直线上，还可以为第一发光单元202包含其他数量的子像素，例如可以包含2个、4个或其他个数的子像素，只要满足显示屏的色彩显示需求即可。
第二发光单元203包括一个第一子像素、一个第二子像素和一个第三子像素。三个子像素可以各自发出不同颜色的光，具体的，例如可以发出红色(R)、绿色(G)、蓝色(B)的光。
归属于第二发光单元203的三个子像素呈三角形排列，第二发光单元203的结构与第一发光单元202呈镜像对称。
第二像素单元的结构不限于此，也可以为三个子像素的中心位于同一直线上，还可以为第二发光单元203包含其他数量的子像素，例如可以包含2个、4个或其他个数的子像素，只要满足显示屏的色彩显示需求即可。
在第一方向上，即在横向上，第一发光单元202连续排布，第二发光单元203也为连续排布。在第二方向上，即在纵向上，第一发光单元202和第二发光单元203交替排布。在显示屏的边缘，不同结构的第一发光单元202和第二发光单元203相互结合并交替排布，从而可以拟合异形显示屏的轮廓线201的形状，边缘显示的画面贴近异形屏的轮廓线201。在微观尺度观察时，能降低显示 的锯齿感。
应当指出的是，这里的第一发光单元202与上例中的第一发光单元102是不同的。这里的第一发光单元202包含三个子像素，上例中的第一发光单元102包含六个子像素。
本申请的实施例提供一种显示装置，包括：前述异形显示屏；电源模块，用于为显示屏供电；存储模块，用于存储媒体信息；处理模块，其与异形显示屏、电源模块和存储模块电性连接，用以控制电源模块的电能供给，并且处理模块将媒体信息显示于异形显示屏。
异形显示屏为输入输出设备，它可将电子信息通过传输设备以图像形式显示到屏幕上。显示屏可以为LCD、CRT、PDP、OLED等，显示的颜色越多则显示的图像越复杂，画面层次也更丰富。
电源模块是可直接贴装于印刷电路板上的电源供应站，为异形显示屏的驱动电路、信息存储模块、图像处理模块供电。电源模块还可以是可接入市电的电源适配器或电压转换装置，用以将市电的电压220v转换为异形显示屏的工作电压。
存储模块用于存储或缓存子像素的驱动信号。计算机领域中采取每一像素用24比特表示，三种原色——红、绿、蓝——各分到8比特。每一种原色的强度依照8比特的最高值28分为256个值。
像素单元的驱动信号指的是三种原色的强度。处理模块与异形显示屏、电源模块和存储模块电性连接。处理模块控制电源模块对各其他模块的电能供给。电源模块供电后，处理模块即时处理图像数据，根据图像数据生成驱动信号输入到异形显示屏，控制异形显示屏的子像素发光。邻近的子像素发出的光混合并最终呈现便于人眼识别的图像。
本申请提供的异形显示屏和集成该异形显示屏的显示装置，采用不同结构的第一发光单元和第二发光单元相互组合并布满异形显示屏，所述不同结构可以是子像素的数目不同，也可以是发光单元所在表面的曲率半径不同，还可以是镜像结构等等。通过在有效显示区的主显示区和边缘显示区设置不同结构的第一发光单元和第二发光单元，以降低边缘显示区在微观尺度观察时呈现明显的锯齿感或颗粒感，以提高异形显示屏的显示品质。
下面介绍本申请的具体应用场景：
对于已经设计好的异形显示屏结构，异形显示屏的轮廓线是确定的。对于具有曲面屏幕的电视或者具有曲面屏幕的便携式终端设备(例如手机)，为了实现异形显示屏的功能，需要对像素单元进行排布。然而，考虑到像素单元是具有一定尺寸的确定形状的物理实体，当像素单元沿着轮廓线排布时，由于轮廓线通常为光滑曲线，两者并不完成重合，所以会呈现一定程度的锯齿状。为了减轻因像素单元拟合轮廓线排布而在显示时存在的锯齿感，可以采用下列方式。
在本申请提供的一种实施例中，使用包含6个子像素的第一发光单元，使用包含3个子像素的第二发光单元。当然，由于第一发光单元中包含的子像素数量多，所以局部白平衡性能好。而使用3个子像素构成的第二发光单元排布于第一发光单元与轮廓线之间，可以很好地减轻显示时的锯齿感。
在3个子像素中，第一像素、第二像素和第三像素可以三角形状排布，也可以沿直线排布。
在本申请提供的另一种实施例中，使用3个子像素的第一发光单元，使用3个子像素的具有另一种结构的第二发光单元。在第一方向上，第一发光单元连续排列。在第一方向上，第二发光单元同样连续排列。在与第一方向相交的第二方向上，第一发光单元和第二发光单元交替排列。这样排列的第一发光单元 和第二发光单元同样可以很好地减轻显示时的锯齿感。
综上，作为本申请解决显示时的锯齿感的手段，一种手段为使不同大小的发光单元组合，即用面积相对较大的发光单元构成显示屏的大部分区域(主显示区域)，而在无法容纳一个完整的面积相对较大的发光单元的区域(边缘显示区域)内布置面积相对较小的发光单元。另一种思路为通过子像素的不同排列方式，形成至少两类面积相对较小的发光单元，面积相对较小的发光单元可以通过错位排列的形式构成显示屏的整个发光区域。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
