画面串扰现象是指显示面板在同时显示两种不同灰阶画面时，不同灰阶画面之间会相互发生干扰。例如，同时显示黑白两种画面，黑色区域受白色区域影响会变得不够黑，白色区域受到黑色区域影响会变得不够白，从而影响显示效果。
目前画面串扰测试方法适用于一体式屏体，而不适用于异形屏。

其中，主屏对副屏的画面串扰度以及副屏对主屏的画面串扰度用于确定主屏与副屏之间的画面串扰影响。
第二方面，本申请实施例提供一种屏体画面串扰测试装置，屏体包括主屏和副屏，副屏至少具有第一功能状态和第二功能状态，副屏在第一功能状态与主屏一并显示画面，该屏体画面串扰测试装置包括：
画面串扰标准参量计算模块，用于在副屏处于第一功能状态且副屏与所述主屏同时显示不同灰阶画面时，根据主屏中心点的亮度以及副屏中心点的亮度确定主屏对副屏的画面串扰标准参量值及副屏对主屏的画面串扰标准参量值；
画面串扰实际参量计算模块，用于根据主屏上主屏中心点以外的n个对比测试点的亮度以及在副屏上副屏中心点以外的n个参考测试点的亮度，确定主屏对副屏的画面串扰实际参量值及副屏对主屏的画面串扰实际参量值，n为大于等于1的整数，n个对比测试点和n个参考测试点一一对应设置；
画面串扰度计算模块，用于根据主屏对副屏的画面串扰标准参量值以及主屏对副屏的画面串扰实际参量值，计算主屏对副屏的画面串扰度，并根据副屏对主屏的画面串扰标准参量值以及副屏对主屏的画面串扰实际参量值，计算副屏对主屏的画面串扰度；其中，主屏对副屏的画面串扰度以及副屏对主屏的画面串扰度用于确定主屏与副屏之间的画面串扰影响。

具体实施方式
下面将详细描述本申请的各个方面的特征和示例性实施例。在下面的详细描述中，提出了许多具体细节，以便提供对本申请的全面理解。
参看图1，画面串扰测试方法为：使显示面板100显示纯白画面，测试纯白画面中非中间区域的多个测试点101的第一亮度值，然后使显示面板100的中间区域显示纯黑画面，而显示面板100除中间区域的四周区域继续显示纯白画面，再次测试多个测试点101的第二亮度值，最后计算每个测试点101的第一亮度值与第二亮度值的差值，当多个测试点101中的一个或多个测试点101的第一亮度值与第二亮度值的差值大于一预设阈值时，判定显示面板的画面串扰测试不合格。该画面串扰测试方法适用于一体式屏体。
参看图2，异形屏包括主屏201和副屏202，203为副屏的轮廓线。
图2中示出的副屏202的形状和位置与摄像头相匹配。在一些实施例中，副屏202的形状、数量、位置也可以体现为其他形式。比如，副屏202的形状可以为矩形、圆形等，数量可以大于一个，位置可以处于边缘或者顶角区域，此处不做限定。
副屏202至少具有第一功能状态和第二功能状态。这里的第一功能状态包括显示功能，第二功能状态包括摄像头功能。副屏202在第一功能状态与主屏201一并显示画面时，呈现为全面屏模式。制备异形屏时，可以在制备主屏201时预留副屏202空间，以在主屏201的基础上进一步制备副屏202，由于主屏201和副屏202需要分别制备，因此，两者在驱动方式、像素结构、相对位置布局等方面可能存在不同。
本申请的发明人发现，对于异形屏(如图2所示)，由于主屏201和副屏202在驱动方式、像素结构、相对位置布局等方面均存在不同，上述适用于一体式屏体的画面串扰测试方法，并不适用于包含分离设计的主副屏的异形屏。
图3为本申请实施例提供的屏体画面串扰测试方法的流程示意图，适 用于包含分离设计的主副屏的异形屏。如图3所示，该屏体画面串扰测试方法包括步骤301至步骤303。
在步骤301中，在副屏处于第一功能状态且副屏与主屏同时显示不同灰阶画面时，根据主屏中心点的亮度以及副屏中心点的亮度确定主屏对副屏的画面串扰标准参量值及副屏对主屏的画面串扰标准参量值。
由于主屏与副屏之间的画面串扰主要分布在相靠近的区域，因此，主屏中心点和副屏中心点之间不存在画面串扰。故可以依据主屏及副屏显示不同的灰阶画面时，主屏中心点的亮度以及副屏中心点的亮度来确定主屏对副屏的画面串扰标准参量值及副屏对主屏的画面串扰标准参量值。
其中，画面串扰标准参量值为画面串扰为0时对应的参量值。
该步骤中，由于主屏中心点的亮度以及副屏中心点的亮度能够反映主屏和副屏间画面串扰为0时的状态，因此，依据主屏及副屏显示不同的灰阶画面时，主屏中心点的亮度以及副屏中心点的亮度来确定主屏对副屏的画面串扰标准参量值及副屏对主屏的画面串扰标准参量值，能够自适应于实际的灰阶显示画面，与采用预设值相比，更接近真实显示状态，准确度也更高。
在步骤302中，根据主屏上主屏中心点以外的n个对比测试点的亮度以及在副屏上副屏中心点以外的n个参考测试点的亮度，确定主屏对副屏的画面串扰实际参量值及副屏对主屏的画面串扰实际参量值，n为大于等于1的整数，n个对比测试点和n个参考测试点一一对应设置。
其中，画面串扰实际参量值为画面串扰不为0时对应的参量值，因此，可以根据主屏上主屏中心点以外的n个对比测试点的亮度以及在副屏上副屏中心点以外的n个参考测试点的亮度，确定主屏对副屏的画面串扰实际参量值及副屏对主屏的画面串扰实际参量值。
由于副屏面积远小于主屏面积，可以先选定副屏上的n个参考测试点的位置之后，再确定主屏上与之相对应的n个对比测试点的位置。
在一些实施例中，由于主屏与副屏之间的画面串扰主要分布在两者相邻近的区域，即主屏与副屏靠的越近，干扰越大。因此，可以使副屏上副屏中心点以外的n个参考测试点均匀分布在副屏的靠近主屏的边缘区域； 主屏上主屏中心点以外的n个对比测试点位于主屏的靠近副屏的边缘区域。并且，针对副屏上副屏中心点以外的n个参考测试点中的每一个参考测试点，在主屏的靠近参考测试点的边缘区域均存在一个对比测试点，对比测试点与参考测试点对应形成一个测试组，且分别位于副屏的轮廓线203的外侧和内侧，以全面且准确地计算主屏对副屏的画面串扰实际参量值及副屏对主屏的画面串扰实际参量值。
参看图4，Z0为主屏中心点，位于主屏的区域中心；F0为副屏中心点，位于副屏的区域中心，由于Z0与F0之间相距较远，因此，主屏中心点和副屏中心点之间不存在画面串扰。
F1、F2、F3为副屏的靠近主屏的边缘区域均匀分布的3个参考测试点，Z1、Z2、Z3为主屏的靠近副屏的边缘区域的3个对比测试点，其中，Z1为主屏的靠近F1的边缘区域的对比测试点，Z1与F1形成一个测试组，Z2为主屏的靠近F2的边缘区域的对比测试点，Z2与F2形成一个测试组，Z3为主屏的靠近F3的边缘区域的对比测试点，Z3与F3形成一个测试组。
在一些实施例中，为了提高主屏对副屏的画面串扰实际参量值及副屏对主屏的画面串扰实际参量值的计算精度，可以使副屏中心点以外的n个参考测试点以及主屏中心点以外的n个对比测试点形成的n个测试组中、每个测试组的对比测试点和参考测试点到副屏的轮廓线203的距离相等。
在一些实施例中，还可以使F1、F2和F3围绕副屏中心均匀分布，以提高测试精度。当主屏环绕副屏设置时，可以使副屏中心点以外的n个参考测试点以及主屏中心点以外的n个对比测试点形成的n个测试组中、每个测试组的对比测试点和参考测试点的连线延长线均经过副屏的中心。也就是说，使Z1与F1的连线延长线、Z2与F2的连线延长线以及Z3与F3的连线延长线相交并经过副屏的中心，以提高主屏对副屏的画面串扰实际参量值及副屏对主屏的画面串扰实际参量值的计算精度。
除主屏中心点Z0和副屏中点F0外，图4中针对主屏和副屏还分别示出了3个非中心测试点(Z1、Z2、Z3以及F1、F2、F3)，非中心测试点的数量越多计算结果越准确，但同时对计算资源的占用越多，耗时越长，因此，可以根据实际情况选择合适的非中心测试点的数量，此处不做限定。
在步骤303中，根据主屏对副屏的画面串扰标准参量值以及主屏对副屏的画面串扰实际参量值，计算主屏对副屏的画面串扰度，并根据副屏对主屏的画面串扰标准参量值以及副屏对主屏的画面串扰实际参量值，计算副屏对主屏的画面串扰度。
其中，主屏对副屏的画面串扰度以及副屏对主屏的画面串扰度用于确定主屏与副屏之间的画面串扰影响。
由于主屏和副屏存在驱动方式以及像素结构的区别，因此，主屏对副屏的画面串扰影响以及主屏对副屏的画面串扰影响可能存在不同，此处同时计算主屏对副屏的画面串扰度以及副屏对主屏的画面串扰度，能够更全面准确地衡量主屏与副屏之间的画面串扰影响。
如上所述，对于具有主屏及副屏的屏体结构，本申请实施例首先根据主屏对副屏的画面串扰标准参量值以及主屏对副屏的画面串扰实际参量值，计算出主屏对副屏的画面串扰度，然后根据副屏对主屏的画面串扰标准参量值以及副屏对主屏的画面串扰实际参量值，计算出副屏对主屏的画面串扰度，最后根据主屏对副屏的画面串扰度以及副屏对主屏的画面串扰度，确定出主屏与副屏之间的画面串扰影响，能够全面准确地衡量主屏与副屏之间的画面串扰影响，适用于异形屏的画面串扰测试，能够提高异形屏的画面串扰测试准确度。
另外，在进行画面串扰标准参量值计算时，本申请实施例选择了以主屏中心点的亮度以及副屏中心点的亮度作为基准，能够自适应于实际灰阶显示画面，与采用预设值相比，更接近真实显示状态，准确度也更高。
在本申请实施例中，亮度单位可以采用cd/m2表示，用于表示发光面明亮程度，具体指发光表面在指定方向的发光强度与垂直且指定方向的发光面的面积之比。亮度单位也可以采用Nt(尼特)，用于表示单位面积上、单位立体角中的光通量。
下面结合图5和图6说明主屏对副屏的画面串扰度计算方法。
在步骤501中，参看图6，使主屏显示第一灰阶画面，副屏显示第二灰阶画面。其中，第一灰阶大于第二灰阶，第一灰阶面面用符号W表示，第二灰阶画面用符号B表示。
对应地，主屏中心点Z0的亮度表示为W_Z0，主屏对比测试点Z1的亮度表示为W_Z1，主屏对比测试点Z2的亮度表示为W_Z2，主屏对比测试点Z3的亮度表示为W_Z3。副屏中心点F0的亮度表示为B_F0，副屏参考测试点F1的亮度表示为B_F1，副屏参考测试点F2的亮度表示为B_F2，副屏参考测试点F3的亮度表示为B_F3。
在步骤502中，计算副屏中心点的亮度与主屏中心点的亮度的比值，并将该比值作为主屏对副屏的画面串扰标准参量值。
示例性地，用S1表示主屏对副屏的画面串扰标准参量值，则有：
S1＝B_F0/W_Z0                (1)
在步骤503中，针对主屏上主屏中心点以外的n个对比测试点中的每一个，计算该对比测试点对应在副屏的边缘区域的参考测试点的亮度与该对比测试点的亮度的比值，并将比值确定为主屏对副屏的基于该对比测试点的画面串扰实际参量值。
示例性地，用RZi表示主屏对副屏的基于对比测试点i的画面串扰实际参量值，则有：
RZ1＝B_F1/W_Z1                (2)
RZ2＝B_F2/W_Z2                (3)
RZ3＝B_F3/W_Z3                (4)
在步骤504中，针对主屏上主屏中心点以外的n个对比测试点中的每一个，计算基于该对比测试点的主屏对副屏的画面串扰标准参量值与画面串扰实际参量值的差值的绝对值，得到n个绝对值，并将n个绝对值中的最大值确定为主屏对副屏的画面串扰度。
示例性地，用D1表示主屏对副屏的画面串扰度，则有：
D1＝max|S1-RZi|              (5)
示例性地，用Q1表示主屏对副屏的画面串扰度阈值(即第一串扰度阈值)，则D1＜Q1时，判定主屏对副屏的画面串扰影响符合品质要求。
下面结合图7和图8说明副屏对主屏的画面串扰度计算方法。
在步骤701中，参看图8，使主屏显示第二灰阶画面，副屏显示第一灰阶画面。其中，第一灰阶大于第二灰阶，第一灰阶面面用符号W表示， 第二灰阶画面用符号B表示。
对应地，主屏中心点Z0的亮度表示为B_Z0，主屏对比测试点Z1的亮度表示为B_Z1，主屏对比测试点Z2的亮度表示为B_Z2，主屏对比测试点Z3的亮度表示为B_Z3。副屏中心点F0的亮度表示为W_F0，副屏参考测试点F1的亮度表示为W_F1，副屏参考测试点F2的亮度表示为W_F2，副屏参考测试点F3的亮度表示为W_F3。
在步骤702中，计算主屏中心点的亮度与副屏中心点的亮度的比值，并将该比值作为副屏对主屏的画面串扰标准参量值。
示例性地，用S2表示副屏对主屏的画面串扰标准参量值，则有：
S2＝B_Z0/W_F0                 (6)
在步骤703中，针对副屏上副屏中心点以外的n个参考测试点中的每一个，计算该参考测试点对应在主屏的边缘区域的对比测试点的亮度与该参考测试点的亮度的比值，并将比值确定为副屏对主屏的基于该参考测试点的画面串扰实际参量值。
示例性地，用RFi表示副屏对主屏的基于参考测试点i的画面串扰实际参量值，则有：
RF1＝B_Z1/W_F1                (7)
RF2＝B_Z2/W_F2                (8)
RF3＝B_Z3/W_F3                (9)
在步骤704中，针对副屏上副屏中心点以外的n个参考测试点中的每一个，计算基于该参考测试点的副屏对主屏的画面串扰标准参量值与画面串扰实际参量值的差值的绝对值，得到n个绝对值，并将n个绝对值中的最大值确定为副屏对主屏的画面串扰度。
示例性地，用D2表示副屏对主屏的画面串扰度，则有：
D2＝max|S2-RFi|              (10)
示例性地，用Q2表示副屏对主屏的画面串扰度阈值为Q2(即第二串扰度阈值)，则D2＜Q2时，判定副屏对主屏的画面串扰影响符合品质要求。
其中，Q1和Q2的取值由客户提供，两者可以相等，也可以不相等， 此处不做限定。在主屏对副屏的画面串扰影响以及副屏对主屏的画面串扰影响均符合品质要求的情况下，可以确定主屏与副屏之间的画面串扰影响符合品质要求，即屏体整体的画面串扰影响符合品质要求。
上文对主屏和副屏进行不同灰阶画面显示时，仅限定第一灰阶大于第二灰阶，未限定灰阶的具体数值。比如，第一灰阶可以为255(显示为纯白)，第二灰阶可以为0(显示为纯黑)，第一灰阶和第二灰阶也可以均处于0～255之间(显示为灰度)。
由于127和255这两个灰阶串扰比较严重，因此，为了更快速、准确、有效地反映全面屏中主屏和副屏之间的画面串扰影响，可以将第一灰阶设为255，第二灰阶设为127。
图9为本申请实施例提供的屏体画面串扰测试装置的结构示意图，图3中的解释说明可以应用于本实施例。
如图9所示，该屏体画面串扰测试装置包括：画面串扰标准参量计算模块901(其具有与步骤301对应的功能)、画面串扰实际参量计算模块902(其具有与步骤301对应的功能)、画面串扰度计算模块903(其具有与步骤301对应的功能)。
其中，画面串扰标准参量计算模块901用于向主屏及副屏提供不同灰阶画面，根据主屏中心点的亮度以及副屏中心点的亮度确定主屏对副屏的画面串扰标准参量值及副屏对主屏的画面串扰标准参量值。
画面串扰实际参量计算模块902用于根据主屏上主屏中心点以外的n个对比测试点的亮度以及在副屏上副屏中心点以外的n个参考测试点的亮度，确定主屏对副屏的画面串扰实际参量值及副屏对主屏的画面串扰实际参量值，n为大于等于1的整数。
画面串扰度计算模块903用于根据主屏对副屏的画面串扰标准参量值以及主屏对副屏的画面串扰实际参量值，计算主屏对副屏的画面串扰度，并根据副屏对主屏的画面串扰标准参量值以及副屏对主屏的画面串扰实际参量值，计算副屏对主屏的画面串扰度。
其中，主屏对副屏的画面串扰度以及副屏对主屏的画面串扰度用于确定主屏与副屏之间的画面串扰影响。
屏体画面串扰测试装置可以为具有独立运算功能的处理器件，也可以集成在已有的屏体画面串扰测试装置中，此处不做限定。
如上所述，对于具有主屏及副屏的屏体结构，本申请实施例首先根据主屏对副屏的画面串扰标准参量值以及主屏对副屏的画面串扰实际参量值，计算出主屏对副屏的画面串扰度，然后根据副屏对主屏的画面串扰标准参量值以及副屏对主屏的画面串扰实际参量值，计算出副屏对主屏的画面串扰度，最后根据主屏对副屏的画面串扰度以及副屏对主屏的画面串扰度，确定出主屏与副屏之间的画面串扰影响，能够全面准确地衡量主屏与副屏之间的画面串扰影响，适用于异形屏的画面串扰测试，能够提高异形屏的画面串扰测试准确度。
