图7为本申请实施例中显示驱动方法的一个具体示例的示意图；
图8为本申请实施例中显示装置的一个具体示例的示意图。
具体实施方式
由于异形显示屏中驱动芯片实际送出至异形开槽处的图形为0灰阶黑色图形，当正常显示画面为255灰阶或高灰阶亮画面时，可能会导致画面显示不良。
下面将结合附图对本申请的技术方案进行清楚、完整地描述，
此外，下面所描述的本申请不同实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互结合。
正如背景技术所述，如图1所示，异形显示屏的驱动芯片1实际送入异形开槽处2的图形为0灰阶黑色图形；当正常显示区3的显示画面为255 灰阶或高灰阶画面时，由于数据走线之间及数据走线与驱动电源(ELVDD)之间的相互耦合作用，在异形开槽处2与正常显示区3的边界位置容易出现横向串扰4(cross talk)，可能会导致数据传输的丢失和传输错误，进而导致画面显示不良。其中，所述的异形显示屏可以是异形AMOLED(Active-matrix organic light-emitting diode，即，有源矩阵有机发光二极体或主动矩阵有机发光二极体)显示屏。或者，进一步地，所述异形显示屏可以是异形AMOLED全面屏。
基于此，本申请提供了一种显示数据的修正方法，如图2所示，该显示数据的修正方法包括：
步骤S1：接收针对异形显示屏的像素单元的显示数据。
步骤S2：判断像素单元是否处于待修正区域。
具体地，可以对异形显示屏的各像素单元配置地址，以便像素单元被独立驱动。对于定制的异形显示屏，该异形显示屏待修正区域的各像素单元的地址集合是确定的，因此，通过判断显示数据对应的像素单元的配置地址是否属于该地址集合，能够判断该像素单元是否处于待修正区域。或者，也可以采用其他方式判断像素单元是否处于待修正区域。
请参见图1，异形显示屏的待修正区域即异形开槽处2。对于显示面板而言，该区域为挖空区域；对于驱动芯片1而言，该区域为正常送入显示数据区域。该区域可以是如图1所示的椭圆形，也可以是如图3所示的矩形或如图4所示的半圆形，还可以是椭圆形、矩形和半圆形的组合图形，本申请不以此为限。
如图5所示，上述步骤S2具体可以包括以下步骤S21至步骤S24：
步骤S21：提取显示数据对应的像素单元的配置地址。
步骤S22：确定待修正区域的各像素单元的地址集合。
步骤S23：判断各配置地址是否属于地址集合。
步骤S24：当配置地址属于地址集合时，判定所述配置地址对应的像素单元处于待修正区域。
具体地，对于定制的异形显示屏，该异形显示屏的各个像素单元对应的配置地址是固定的，且异形显示屏的待修正区域的各个像素单元的地址也是固定的。因此，可以将待修正区域的各个像素单元的地址形成一个地址集合，在提取出显示数据对应的像素单元的配置地址后，将配置地址与对应于待修正区域的地址集合进行比较，以判断各个配置地址是否属于地址集合。当确定出某个配置地址属于地址集合时，则判定该配置地址对应的像素单元处于待修正区域。
步骤S3：当像素单元相对于异形显示屏处于待修正区域时，对像素单元对应的显示数据进行修正，生成修正后的显示数据。
本申请实施例提供的显示数据的修正方法，通过判断接收到的显示数据对应的像素单元的配置地址是否属于地址集合，判断像素单元是否处于待修正区域，从而通过将处于待修正区域的像素单元对应的显示数据设置为预设灰阶值、高阻态或在待修正区域的预设方向上设置渐变灰阶值的方式，对处于待修正区域的像素单元对应的显示数据进行修正，从而减轻以至消除了横向串扰，实现了异形显示屏画面的正常显示。
可选地，在本申请的一些实施例中，对像素单元对应的显示数据进行修正，可以是将处于待修正区域的像素单元对应的显示数据设置为预设灰阶值，该预设灰阶值为介于0灰阶至255灰阶之间的中间灰阶值。例如可以设置为127灰阶或128灰阶，也可以设置为中间灰阶区间内的某个值，例如可以是120灰阶至135灰阶的范围中的一个灰阶值。
可选的，在本申请的另外一些实施例中，对像素单元对应的显示数据进行修正，可以是将处于待修正区域的像素单元对应的显示数据设置为高阻态。
可选地，在本申请的另外一些实施例中，对像素单元对应的显示数据进行修正，还可以是将处于待修正区域的像素单元对应的显示数据设置为多个灰阶值，每个灰阶值的显示数据分别对应待修正区域的至少一个像素单元。例如，将待修正区域划分为多个子区域，每个子区域内具有至少一个像素单元，其中，每个子区域对应一个灰阶值。即，可以理解为，同一子区域内的像素单元对应一个灰阶值。当同一子区域内具有一个像素单元时，则灰阶值与像素单元一一对应；当同一子区域内具有两个及以上的像素单元时，则一个灰阶值对应同一子区域内的两个及以上的像素单元。
其中，可选地，将处于所述待修正区域的像素单元对应的显示数据的灰阶值设置为在待修正区域的预设方向上渐变。例如，请参见图1，所述的预设方向为由下向上，具体为将待修正区域2中从靠近正常显示区3到远离正常显示区3的方向定义为由下向上。那么，所述待修正区域的像素单元对应的显示数据对应的灰阶值在由下向上的方向上由大变小。
具体地，多个灰阶值中的最大值为127灰阶或128灰阶，多个灰阶值中的最小值为0灰阶。例如可以是将待修正区域的灰阶值设置为由下向上的方向上灰阶值由127灰阶至0灰阶递减。该实施方式只是示意性地举例说明，在本申请的其他实施例中还可以是采用其他的方式，本申请不以此为限。
本申请实施例还提供了一种显示驱动方法，如图6所示，该显示驱动方法包括：
步骤S4：接收针对异形显示屏的像素单元的显示数据，详细内容可参见上述显示数据的修正方法实施例的步骤S1的相关描述。
步骤S5：将显示数据输出至异形显示屏的各像素单元。具体地，在接收到显示数据之后，对该显示数据不做处理，直接将该显示数据(即，全分辨率无处理图像全图)输出至异形显示屏的各像素单元。
步骤S6：判断像素单元是否处于待修正区域。详细内容可参见上述显示数据的修正方法实施例的步骤S2的相关描述。
步骤S7：当像素单元处于待修正区域时，对像素单元对应的显示数据进行修正，生成修正后的显示数据。详细内容可参见上述显示数据的修正方法实施例的步骤S3的相关描述。
步骤S8：驱动处于待修正区域的像素单元对修正后的显示数据进行显示。
本申请实施例提供的异形显示屏的显示驱动方法，先将接收到的显示数据输出至异形显示屏的各像素单元，然后判断像素单元是否处于待修正 区域，通过将处于待修正区域的像素单元对应的显示数据设置为预设灰阶值、高阻态或在待修正区域的预设方向上设置渐变灰阶值的方式，对处于待修正区域的像素单元对应的显示数据进行修正，从而减轻以至消除了横向串扰，实现了异形显示屏画面的正常显示。
在具体应用中,如图7所示,异形显示屏的显示驱动方法可以包括以下步骤:
步骤S9:应用处理器(AP,Application Processor)将全分辨率无处理矩形图像传输至驱动芯片。
步骤S10:驱动芯片将接收到的上述图像全图输出到显示面板(panel)。
步骤S11：对U区(异形开槽区)局部开窗，将修正后的显示数据单独送入U区，修正方法可参考上述显示数据的修正方法实施例中的相关描述。
通过上述步骤S9至步骤S11，本申请实施例提供的异形显示屏的显示驱动方法实现了对U区显示数据的修正，减轻以至消除了横向串扰，实现了异形显示屏画面的正常显示。
