具体实施方式
为了使本申请的目的、技术方案及优点更加清楚明白，下面通过具体实施方式结合附图对本申请实施例作进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本申请，并不用于限定本申请。
为了尽可能避免或降低电子设备的屏幕产生色差而影响视觉体验，本实施例提供的屏幕显示控制方法，在通过电子设备的屏幕显示过程中，获取电子设备的待校准屏幕的校准参数，该校准参数为基于该待校准屏幕与预设标准屏幕之间的色差得到的；然后根据获取的校准参数生成待校准屏幕的补偿图层，将得到的补偿图层与待校准屏幕的其他图层进行叠加显示，使得电子设备的待校准屏幕的颜色显示效果与预设标准屏幕的颜色显示效果基本保持一致，从而避免电子设备的屏幕产生色差时影响视觉体验。
在本实施例的一种可选示例中，待校准屏幕的色差可为待校准屏幕与预设标准屏幕相比所产生的色差。为了便于理解，本实施例下面结合一种示例的屏幕显示控制方法进行说明，该方法参见图1所示，其包括：
S101：获取电子设备的待校准屏幕的校准参数；
S102：根据获取的校准参数生成待校准屏幕的补偿图层；
S103：将生成的补偿图层与待校准屏幕的其他图层进行叠加显示。
本实施例S101中的校准参数为基于电子设备的待校准屏幕与预设标准屏幕之间的色差得到的。且应当理解的是，S101中的获取待校准屏幕的校准参数包括但不限于以下方式之一：
方式一：在一示例中，该校准参数可以是预先得到保存的，此时S101中的获取则可为获取预先保存的校准参数；
方式二：在另一示例中，该校准参数也可以是实时获取的，此时S101中的获取则可为根据电子设备的待校准屏幕与预设标准屏幕之间的色差实时获取校准参数。
在本实施例中，具体采用哪种获取方式获取校准参数可以根据具体应用场景灵活选择确定。
另外，在本实施例中，电子设备可以为仅设置有一个屏幕(即一个显示屏)的单屏幕设备，也可为设置有两个屏幕以上(例如两个显示屏、或 三个显示屏等)多屏幕设备。
在一示例中，当电子设备为单屏幕设备时，例如该电子设备仅包括第一屏幕，此时本实施例中的预设标准屏幕可为电子设备之外的其他设备的屏幕。在该示例中，可以在但屏幕设备生成过程中，将其第一屏幕与预设标准屏幕进行显示比较获取二者的色差从而得到校准参数，和/或，在单屏幕电子设备出厂使用过程中(例如使用预设时长后或检测到屏幕老化情况满足预设条件时等)，将当前的第一屏幕与预设标准屏幕进行显示比较获取二者的色差从而得到校准参数。在本示例中，预设标准屏幕可为满足预设标准显示条件的屏幕，且预设标注显示条件具体可根据应用场景需求灵活设置。
在另一示例中，当电子设备为多屏幕设备时，预设标准屏幕可为电子设备之外的其他设备的屏幕，也可为电子设备的其中一个屏幕。例如当该电子设备为包括第一屏幕和第二屏幕的双面屏设备时，此时在一种应用场景中，可设置第一屏幕为预设标准屏幕，第二屏幕为待校准屏幕，或设置第二屏幕为预设标准屏幕，第一屏幕为待校准屏幕，此时则只需针对双面屏设备的第一屏幕或第二屏幕生成对应的补偿图层进行叠加显示；在另一种应用场景中，也可设置电子设备的第一屏幕和第二屏幕都为待校准屏幕，此时的预设标准屏幕可为电子设备之外的其他设备的屏幕，且该应用场景中的预设标准屏幕可为满足预设标准显示条件的屏幕，且预设标注显示条件具体可根据应用场景需求灵活设置；此时则需针对双面屏设备的第一屏幕和第二屏幕分别生成对应的补偿图层进行叠加显示；当然若某一屏幕与预设标准屏幕之间没有色差时，针对该屏幕则可选择性的不生成补偿图层，或生成一个全透明的空白补偿图层。
应当理解的是，对于包括三个或三个以上屏幕的电子设备，待校准屏幕和预设标准屏幕的设置方式也可采用上述所示例的方式，在此不再赘述。
在本申请的一种可选实施例中，根据待校准屏幕与预设标准屏幕之间的色差获取校准参数的过程参见图2所示，包括：
S201：根据待校准屏幕与预设标准屏幕的显示差异，确定待校准屏幕上需要进行色差补偿的待补偿区域。
在本实施例中，确定出的需要进行色差补偿的待补偿区域可能是一个，也可能是两个以上，是一个时，该区域有可能覆盖整个屏幕，也可能是屏幕中的其中一部分区域。当然，在一些情况下，确定出的待补偿区域个数也可能为0。
应当理解的是，在本实施例中，待补偿区域的确定和选择可通过手动实现，例如由操作人员比对分析待校准屏幕与预设标准屏幕存在显示差异的区域，并在待校准屏幕上划分出该部分区域作为待补偿区域。在本实施例中，待补偿区域的确定和选择也可通过预先设定的算法自动计算分析实现。
S202：获取待补偿区域的区域确定参数，以及待补偿区域与预设标准屏幕上对应区域的色差值。
例如，假设在一种示例中，针对一个待校准屏幕，确定出其上存在两个待补偿区域，本实例中分别称为第一待补偿区域和第二待补偿区域，则分别获取第一待补偿区域的第一区域确定参数和第二待补偿区域的第二区域确定参数，并分别获取第一待补偿区域的第一色差值和第二待补偿区域的第二色差值。且在本示例中，区域确定参数和色差值的获取过程并无严格的时序限制，二者可同时获取，也可不同时获取。
另外，应当理解的是，在本实施例中，待校准屏幕与预设标准屏幕上对应区域的色差值的具体计算方式可以根据应用场景灵活确定。其中，色值是指一种颜色在不同的颜色模式中所对应的颜色值。而颜色模式包括但不限于红绿蓝模式(RGB模式)(其中R代表红色，G代表绿色，B代表蓝 色)、印刷色彩模式(即CMYK模式，其中，C代表青色，M代表洋红，Y代表黄色，K代表黑色)，色相饱和度亮度(Hue-Saturation-Brightness，HSB)模式或LAB模式(其中，L代表亮度，A代表颜色是从深绿色(底亮度值)到灰色(中亮度值)再到亮粉红色(高亮度值)；B代表颜色是从亮蓝色(底亮度值)到灰色(中亮度值)再到黄色(高亮度值)。LAB模式的色域最宽，它包括RGB色域和CMYK色域中的所有颜色，在使用LAB模式进行转换时可不会造成任何色彩上的损失。其中色差(Chromatic Aberration，CA)它表示为在一种颜色模式中两种颜色的色值的差别，其单位为美国国家标准局(National Bureau of Standard，NBS)，在数学上由颜色空间中两个色点间的距离表示。
在本实施例中，可以将待校准屏幕和标准屏幕在相同的模式下显示相同的颜色图谱，对于待校准屏幕中与标准屏幕对应区域存在色差的区域(也即待校准区域)，可以记录待校准屏幕当前显示的色彩作为初始色彩，然后改变待校准屏幕中该区域的色彩直到其显示效果与标准屏幕中对应区域的显示效果无或基本无色差，将此时该待校准屏幕中该区域的色彩作为目标色彩；然后计算目标色彩与初始色彩的差值得到色差，该色差则可作为待校准屏幕与标准屏幕对应区域的色差值。且应当理解的是，本实施例中待校准区域的划分方式可以根据具体应用场景灵活设定。
S203：将待补偿区域的区域确定参数和色差值关联保存。
例如，将第一待补偿区域的第一区域确定参数和第一色差值关联保存，并将第二待补偿区域的第二区域确定参数和第二色差值关联保存。应当理解的是，当待补偿区域的个数大于2个时或为1个时，待补偿区域的区域确定参数和色差值的关联保存方式以此类推，在此不再赘述。
在本申请的一种可选实施例中，所述根据待校准屏幕的校准参数生成待校准屏幕的补偿图层的过程参见图3所示，包括：
S301：生成与待校准屏幕匹配的空白图层；
S302：根据校准参数中关联保存的区域确定参数和色差值，确定出空白图层上待渲染的区域，并根据对应的色差值对相应待渲染的区域进行渲染，并将图层设置为透明，得到补偿图层。
例如，仍以上述待校准屏幕存在第一待补偿区域和第二待补偿区域的示例进行示例说明。在该示例中，则可根据第一区域确定参数和第二区域确定参数确定出图层上待渲染的第一待渲染区域和第二待渲染区域，然后根据分别根据对应的第一色差值和第二色差值对第一待渲染区域和第二待渲染区域进行渲染处理，也即根据第一色差值和第二色差值对第一待渲染区域和第二待渲染区域的显示颜色进行设置。应当理解的是，当待补偿区域的个数大于2个时或为1个时，对空白图层的渲染过程以此类推，在此不再赘述。
另外，应当理解的是，在本实施例中，将图层设置为透明(也即将图层的alpha值设置为0(全透))的步骤，与对图层进行上述渲染的步骤可以同时进行，也可不同时进行，且不同时进行时，两个步骤之间的执行顺序可以灵活设置，例如可以先将图层设置为透明之后，再对其按上述过程进行渲染，也可先对图层按上述过程渲染之后，再将其设置为透明。
在本申请的一种可选实施例中，所述将待校准屏幕的补偿图层与待校准屏幕的其他图层进行叠加显示可包括：将待校准屏幕的补偿图层设置于待校准屏幕的其他图层之上进行叠加显示，也即将该补偿图层设置于待校准屏幕的所有图层的最上方，使得电子设备的待校准屏幕的颜色显示效果与预设标准屏幕的颜色显示效果基本保持一致，从而尽量避免或减少电子设备的屏幕产生色差时影响视觉体验。
为了便于理解，本实施例下面以电子设备为具有两个以上显示屏(即屏幕)的电子设备，包括各种双面屏电子设备，甚至三屏及以上的电子设 备。本实施例下面一双面屏电子设备为示例进行说明。
本实施例中的双面屏电子设备可以是各种形式的双屏智能电子设备。例如参见图4-1至图4-3所示的一种双面屏电子设备，在图4-1所示状态下，双面屏电子设备4的两个显示屏处于折叠状态，位于电子设备正面的第一屏幕41面对用户。在图4-2所示状态下，双面屏电子设备1的两个显示屏处于打开过程中的状态，第一屏幕41和第二屏幕42可相对转动实现展开，最终的一种示例展开状态可参见图4-3所示，此时第一屏幕41和第二屏幕42处于同一个平面或基本处于同一个平面。
又例如参见图5-1至图5-2所示的一种双面屏电子设备5，该双面屏电子设备5具有处于电子设备正面的第一屏幕51，以及处于电子设备背面的第二屏幕52，两个显示屏的位置是固定的。第一屏幕51和第二屏幕52的尺寸可相同，也可不同，具体可根据需求灵活设置。例如一种示例中可设置第二屏幕52的尺寸小于第一屏幕51。
应当理解的是，本实施例中的双面屏电子设备并不限于上述示例结构，例如在某些示例中，其第一屏幕和第二屏幕都同时位于电子设备的正面等。
为了便于理解，本实施例下面以图4-1至图4-3所示的双面屏电子设备的应用进行示例说明，但应当理解的是，对于其他形式的多面屏电子设备的显示控制过程类似，在此不再赘述。
在一些应用场景中，图4-1至图4-3所示的双面屏电子设备包括但不限于以下四种显示的模式中的至少一种：
大A模式：两个屏作为一个屏来显示同一个应用，各显示一个应用的一部分，可选地，可根据横竖屏的变化情况分别显示应用的左右半部或者上下半部。
AB模式：两个屏分别显示不同的应用，此时两个屏类似于两个设备的显示屏，二者之间可基本不存在什么连续或者关联性。
AA模式(即镜像模式)：两个屏同时显示同一个应用，但是每个屏都会完全的显示应用的所有部分，只是它们是按照轴对称的形式显示。
AX模式：当前只有一个显示屏开启可用，例如第一屏幕开启，第二屏幕关闭；或第一屏幕关闭，第二屏幕开启)。
在上述模式中，AA模式、AB模式、大A模式实现的前提都是设备的两个显示屏当前都需要处于开启状态，如果当前两个屏幕存在色差，那么该现象极易被发现，尤其是在大A模式或AA模式下，这种现象会更为明显，导致用户体验的满意度差。本实施例提供的方法屏幕显示控制方法可适用于上述四种模式，也可仅针对上述四种模式中的部分模式，例如可在判断设备处于AA模式、AB模式、大A模式时，或处于AA模式、大A模式时，才启用本实施例提供的屏幕显示控制方法对第一屏幕和/或第二屏幕进行显示控制。在本实施例中，将双面屏电子设备的第一屏幕作为待校准屏幕，第二屏幕作为预设标准屏幕(当然在一些应用场景中，也可将双面屏电子设备的第二屏幕作为待校准屏幕，第一屏幕作为预设标准屏幕，或者直接将双面屏电子设备的第一屏幕和第二屏幕都作为待校准屏幕，采用其他设备的屏幕作为预设标准屏幕)。在本实施例中，通过校准计算得出两个屏幕各区域之间的色差值，有了各个区域色差值之后，可以在电子设备的第一屏幕的显示图层中添加一个补偿图层，这个补偿图层可按照上述各区域色色差设置颜色值及alpha值，这里的颜色值和alpha值就是通过计算得出的两个屏幕对应区域的色差值，只需要在待校准屏幕(即第一屏幕)中添加一个补偿图层，即可使得用户最终看到的第一屏幕和第二屏幕基本无色差，提升视觉效果。对于具有两个以上屏幕的设备也可采用该控制方式，使得多个屏幕基本无色差。
在一种示例中，该控制过程可包括校准参数获取过程，以及显示过程中的补偿处理过程。
一种示例中，校准参数获取过程可包括：让第一屏幕和第二屏幕进入校准对比界面，例如让两个屏幕显示白色，确定第一屏幕为待校准屏幕，第二屏幕为预设标准屏幕，确定一屏幕相对第二屏幕需要进行校准的区域，也即待校准区域，例如可包括但不限于显示偏红或者偏绿的区域；然后可通过线性的显示红色及绿色到待校准屏幕，初步为各个待校准区域选择合适的色差并确认，将这些区域的色差值存储起来作为后续显示补偿中进行颜色填充的参数；并可将确定各待校准区域的区域参数与各交校准区域的色差值进行关联保存。
一种示例中，显示过程中的补偿处理过程可包括：在电子设备进入正常开机显示过程，当系统框架启动完成并且尚未进入应用界面之前，可在窗口管理系统中读取校准参数获取过程得到的校准参数(当然此时也可实时的按照上述参数获取过程获取校准参数)，根据校准参数添加一个补偿图层到待校准屏幕，具体可设置其处于待校准屏各涂层的最上方，且可设置对应区域的色差(即补偿色)作为该补偿图层中对应区域的显示色，并可设置补偿图层的alpha值为全透明。
通过本实施例提供的方法，可通过添加补偿图层补偿色差的方式将双屏的色差补齐，从而达到双屏显示无色差的视觉效果。下面结合一种示例的校准参数获取过程为示例进行说明，请参见图6所示，包括:
S601：双面屏电子设备进入校准界面，此时可在第一屏幕和第二屏幕同时显示白色。
S602：确定是否需要进行校准，如是，执行S603；否则，执行S608。
在一种示例中，可通过操作人员或预设算法根据两个屏显示情况判断是否需要进行校准，若无色差则不需要进行校准进入步骤S608，若有色差则需要进行校准进入S603，例如可通过选中待校准屏幕(即第一屏幕)上对应的控制图标，触发将当前屏幕作为待校准屏进入校准流程。
S603：在待校准屏幕确定与标准屏幕有色差的区域，选定一个或者多个色差区域作为待校准区域。
例如，选定的待校准区域参考图7所示，图7中C1和C2所标记的两个区域为待校准区域，并可获取确定C1和C2的区域确定参数。
S604：在选定的待校准区域上通过对色彩RGB各个分量线性递减的方式显示色谱。
在本示例中，可依次取出图7中圈定的待校准区域作为当前待校准区域进入S604，若所有已选定区域均已完成校准，则校准完毕。
S605：根据待校准区域色谱的显示，对比另一个预设标准屏幕，选择一个颜色与其一致的色彩，并进行预览对比，直至最终两屏幕预览显示色彩一致。
S606：根据上一步骤选定的色彩(即目标色彩)，计算出当前待校准屏幕色彩(即初始色彩)与上一步骤选择的目标色彩的色差值。
S607：将待校准区域(例如C1和C2区域)的区域确定参数和色差值写入文件保存下来。
S608：说明第一屏幕和第二屏幕两者无色差，可推出校准流程或则生成色差值为0的文件进行保存。
下面结合一种示例的显示过程中的补偿处理过程进行说明，请参见图8所示，包括:
S801：电子设备开机启动，窗口、屏幕等进入就绪即将启动的应用窗口界面。
S802：读取校准参数获取过程写入的校准信息文件，判断读取是否成功，如是，执行S803；否则，执行S806。
当然在本步骤中可以采用图6所示的方式实时获取校准参数。
S803：解析校准信息文件内容得到对应的区域确定参数和色差值。
在本申请的一种可选实施例中，当读取到的色差值为0时，也可直接转至S806。
S804：生成一个补偿图层，并使用S803解析出的区域确定参数和色差值来渲染该补偿图层，例如假设一补偿图层的渲染区域参见图9所示。
S805：将S804生成的补偿图层添加到待校准屏幕中，并将该补偿图层始终显示在待校准屏幕所有图层的最上方。例如，一种叠加显示示意图可参见图10所示，其中1001、1002和1003分别为壁纸图层(Wallpaper)、应用图层(APP)和状态栏图层(StatusBar)，1004则为补偿图层1004，且补偿图层1004始终处于壁纸图层1001、应用图层1002和状态栏图层1003上方。当然，如果是以双面屏电子设备之外的其他设备的屏幕作为标准屏幕时，在一种示例中，在第一屏幕和第二屏幕中都可生成补偿图层1004进行叠加显示。
S806：进入正常的应用启动流程。
可见，通过本实施例提供的显示控制方法，可以使得双面屏电子设备的两块屏幕的颜色基本无色差显示，因此可提升双面屏电子设备屏幕显示的一致性和用户体验的满意度。
本实施例还提供了一种屏幕显示控制装置，该屏幕显示控制装置可设置于设备中，参见图11所示，包括：
参数获取模块1101，配置为获取电子设备的待校准屏幕的校准参数。

显示控制模块1103，配置为将所述图层生成模块1102生成的补偿图层与待校准屏幕的其他图层进行叠加显示，具体的叠加显示过程参见上述各实施例所示，在此也不再赘述。
在本申请的一种可选实施例中，当电子设备为单屏幕设备时，例如该电子设备仅包括第一屏幕，此时本实施例中的预设标准屏幕可为电子设备之外的其他设备的屏幕。在该示例中，可以在但屏幕设备生成过程中，将其第一屏幕与预设标准屏幕进行显示比较获取二者的色差从而得到校准参数，和/或，在单屏幕电子设备出厂使用过程中(例如使用预设时长后或检测到屏幕老化情况满足预设条件时等)，将当前的第一屏幕与预设标准屏幕进行显示比较获取二者的色差从而得到校准参数。在本示例中，预设标准屏幕可为满足预设标准显示条件的屏幕，且预设标注显示条件具体可根据应用场景需求灵活设置。
在本申请的一种可选实施例中，当电子设备为多屏幕设备时，预设标准屏幕可为电子设备之外的其他设备的屏幕，也可为电子设备的其中一个屏幕。例如当该电子设备为包括第一屏幕和第二屏幕的双面屏设备时，此时在一种应用场景中，可设置第一屏幕为预设标准屏幕，第二屏幕为待校准屏幕，或设置第二屏幕为预设标准屏幕，第一屏幕为待校准屏幕，此时则只需针对双面屏设备的第一屏幕或第二屏幕生成对应的补偿图层进行叠加显示；在另一种应用场景中，也可设置电子设备的第一屏幕和第二屏幕都为待校准屏幕，此时的预设标准屏幕可为电子设备之外的其他设备的屏幕，且该应用场景中的预设标准屏幕可为满足预设标准显示条件的屏幕，且预设标注显示条件具体可根据应用场景需求灵活设置；此时则需针对双面屏设备的第一屏幕和第二屏幕分别生成对应的补偿图层进行叠加显示；当然若某一屏幕与预设标准屏幕之间没有色差时，针对该屏幕则可选择性的不生成补偿图层，或生成一个全透明的空白补偿图层。
应当理解的是，对于包括三个或三个以上屏幕的电子设备，待校准屏幕和预设标准屏幕的设置方式也可采用上述所示例的方式，在此不再赘述。
在本申请的一种可选实施例中，所述参数获取模块1101，配置为根据待校准屏幕与预设标准屏幕的显示差异，确定待校准屏幕上需要进行色差补偿的待补偿区域，并获取待补偿区域的区域确定参数，以及待补偿区域与预设标准屏幕上对应区域的色差值，并将待补偿区域的区域确定参数和色差值关联保存。
在本实施例中，确定出的需要进行色差补偿的待补偿区域可能是一个，也可能是两个以上，是一个时，该区域有可能覆盖整个屏幕，也可能是屏幕中的其中一部分区域。当然，在一些情况下，确定出的待补偿区域个数也可能为0。
应当理解的是，在本实施例中，待补偿区域的确定和选择可通过手动实现，例如由操作人员比对分析待校准屏幕与预设标准屏幕存在显示差异的区域，并在待校准屏幕上划分出该部分区域作为待补偿区域。在本实施例中，待补偿区域的确定和选择也可通过预先设定的算法自动计算分析实现。
例如，假设在一种示例中，针对一个待校准屏幕，确定出其上存在两个待补偿区域，本实例中分别称为第一待补偿区域和第二待补偿区域，则分别获取第一待补偿区域的第一区域确定参数和第二待补偿区域的第二区域确定参数，并分别获取第一待补偿区域的第一色差值和第二待补偿区域的第二色差值。且在本示例中，区域确定参数和色差值的获取过程并无严格的时序限制，二者可同时获取，也可不同时获取。
例如，将第一待补偿区域的第一区域确定参数和第一色差值关联保存，并将第二待补偿区域的第二区域确定参数和第二色差值关联保存。应当理解的是，当待补偿区域的个数大于2个时或为1个时，待补偿区域的区域 确定参数和色差值的关联保存方式以此类推，在此不再赘述。
在本申请的一种可选实施例中，所述图层生成模块1102，配置为生成与待校准屏幕匹配的空白图层，根据校准参数中关联保存的区域确定参数和色差值，确定出空白图层上待渲染的区域，并根据对应的色差值对相应待渲染的区域进行渲染，并将图层设置为透明，得到补偿图层。
例如，仍以上述待校准屏幕存在第一待补偿区域和第二待补偿区域的示例进行示例说明。在该示例中，则可根据第一区域确定参数和第二区域确定参数确定出图层上待渲染的第一待渲染区域和第二待渲染区域，然后根据分别根据对应的第一色差值和第二色差值对第一待渲染区域和第二待渲染区域进行渲染处理，也即根据第一色差值和第二色差值对第一待渲染区域和第二待渲染区域的显示颜色进行设置。应当理解的是，当待补偿区域的个数大于2个时或为1个时，对空白图层的渲染过程以此类推，在此不再赘述。
另外，应当理解的是，在本实施例中，将图层设置为透明(也即将图层的alpha值设置为0(全透))的步骤，与对图层进行上述渲染的步骤可以同时进行，也可不同时进行，且不同时进行时，两个步骤之间的执行顺序可以灵活设置，例如可以先将图层设置为透明之后，再对其按上述过程进行渲染，也可先对图层按上述过程渲染之后，再将其设置为透明。
在本申请的一种可选实施例中，所述显示控制模块1103，配置为将待校准屏幕的补偿图层设置于待校准屏幕的其他图层之上进行叠加显示，也即将该补偿图层设置于待校准屏幕的所有图层的最上方，使得电子设备的待校准屏幕的颜色显示效果与预设标准屏幕的颜色显示效果基本保持一致，从而尽量避免或减少电子设备的屏幕产生色差时影响视觉体验。
应当理解的是，上述参数获取模块1101、图层生成模块1102和显示控制模块1103的功能可通过电子设备的处理器或控制器实现。且通过本实施 例提供的屏幕显示控制装置，可使得电子设备的待校准屏幕的显示效果与预设标准屏幕的显示效果基本保持一致，从而避免电子设备的待校准屏幕产生色差时影响视觉体验，提升用户体验满意度。
