本申请首先提出一种电子墨水屏的控制方法，该控制方法应用于电子墨水屏。
电子墨水屏可包括多个电子墨水胶囊，该多个电子墨水胶囊可阵列排布于电子墨水屏的基板上，也可按照其它方式进行排布，具体可根据实际需求而定，此处不作限定。具体地，参见图6，图6是本申请电子墨水屏的一实施例的结构示意图，如图6所示，在一示例中，电子墨水屏10包括多个电子墨水胶囊11，多个电子墨水胶囊11包括目标胶囊111。
单个电子墨水胶囊中包括带正电荷的第一颜色微粒和带负电荷的第二颜色微粒，举例说明，在黑白电子墨水屏中，单个电子墨水胶囊中可包括带正电荷的白色微粒和带负电荷的黑色微粒，或者，带正电荷的黑色微粒和带负电荷的白色微粒，根据电子墨水屏所要显示的颜色的不同，该第一颜色微粒的颜色和该第二颜色微粒的颜色还可以是其它颜色组合，具体可根据实际需求而定，此处不作限定。
可通过向电子墨水胶囊发送相应的控制电压信号以对电子墨水胶囊施加相应的电场，使得电子墨水胶囊展示相应的颜色，完成颜色显示。该控制电压信号的幅值范围为预设最大负压值到预设最大正压值，在一电子墨水胶囊所对应的控制电压信号的幅值处于不同电压值时，可基于相应电场对电子墨水胶囊的作用，使得该电子墨水胶 囊基于不同数量组合的第一颜色微粒和第二颜色微粒展示不同的颜色。
可将多个电子墨水胶囊中的一胶囊作为目标胶囊，控制方法包括：
步骤S11：在预设时段内，使目标胶囊对应的正压刷新流程的次数和负压刷新流程的次数之间的差值不大于预设差值阈值。
其中，正压刷新流程包括：将控制电压信号的幅值提升至预设最大正压值，再将控制电压信号的幅值降低，以使目标胶囊基于控制电压信号进行颜色显示，以完成一帧的刷新。
负压刷新流程包括：将控制电压信号的幅值降低至预设最大负压值，再将控制电压信号的幅值提升，以使目标胶囊基于控制电压信号进行颜色显示，以完成一帧的刷新。
具体地，在单次正压刷新流程中，具体步骤可包括：
在目标胶囊完成一帧对应的颜色显示后，可控制目标胶囊所接收的控制电压信号的幅值进行提升，直至该幅值达到预设最大正压值，之后，再将幅值达到该预设最大正压值的控制电压信号的幅值进行降低，直至该幅值达到目标颜色所对应的目标电压值，以使得目标胶囊能够基于目标电压值的控制电压信号，显示出目标颜色，完成目标胶囊所对应的一帧的刷新，其中，目标颜色为目标胶囊在当前帧所要显示的颜色。
相应的，在单次负压刷新流程中，具体步骤可包括：
在目标胶囊完成一帧对应的颜色显示后，可控制目标胶囊所接收的控制电压信号的幅值进行降低，直至该幅值达到预设最大负压值，之后，再将幅值达到该预设最大负压值的控制电压信号的幅值进行提升，直至该幅值达到目标颜色所对应的目标电压值，以使得目标胶囊能够基于目标电压值的控制电压信号，显示出目标颜色，完成目标胶囊所对应的一帧的刷新。
举例说明，参见图1，图1是本申请控制电压信号的一实施例的波形示意图，如图1所示，假设预设时长为两帧时长，则在该两帧时长中的第一帧时长中，可在目标胶囊完成一帧刷新后，通过执行负压刷新流程以完成一帧的刷新，并在之后通过执行正压刷新流程完成另一帧的刷新，以确保两帧时长内，目标胶囊接收到幅值为预设最大负压值的控制电压信号的次数与接收到幅值为预设最大正压值的控制电压信号的次数相等。
区别于现有技术，在本申请的技术方案中，通过使预设时段内目标胶囊对应的正压刷新流程的次数和负压刷新流程的次数之间的差值不大于预设差值阈值，能够使得预设时段内目标胶囊对应的正压刷新流程的次数与负压刷新流程的次数较为接近，进而使得该预设时段内目标胶囊所接收的控制电压信号的幅值抵达最大正压值和最大负压值的次数相近，避免出现目标胶囊长期接收正压信号或负压信号的情况，减小电子墨水屏中的电子墨水胶囊受到损伤的可能性，进而减缓了电子墨水屏中的残影现象，改善了电子墨水屏的显示效果。
此外，相较于将控制电压信号的幅值从一帧对应的目标电压值直接调整至另一帧对应的目标电压值的方式，上述先将控制电压信号的幅值调整至预设最大正压值/预设最大负压值，再以预设最大正压值/预设最大负压值为基准，将控制电压信号的幅值调整至相应的目标电压值的方式，能够使得控制电压信号被调整后所达到的目标电压值更精准，也即，能够使目标胶囊所显示的颜色更准确，从而使得电子墨水屏中的残影现象进一步减少，进一步改善了电子墨水屏的显示效果。
具体地，步骤S11具体可包括：
在预设时段内，使目标胶囊对应的正压刷新流程的次数和负压刷新流程的次数相等。
基于上述方式，能够使目标胶囊基于正压刷新流程进行相应的一帧的颜色显示作业的次数，与目标胶囊基于负压刷新流程进行相应的一帧的颜色显示作业的次数相等，也即，使得该预设时段内目标胶囊所接收的控制电压信号的幅值抵达最大正压值和最大负压值的次数完全相同，使得目标胶囊分别受正压和负压的控制程度相同，将目标胶囊受到损伤的可能性降到最低，提高了电子墨水屏的可靠性。
在一实施例中，预设时段为与相邻的两帧对应的时段，将两帧中的一帧作为第一帧而另一帧作为第二帧。
步骤S11具体可包括：
在与第一帧对应的时段中，将控制电压信号的幅值提升至预设最大正压值，再将控制电压信号的幅值降低，以使目标胶囊基于控制电压信号进行颜色显示，以完成第一帧的刷新，而在与第二帧对应的时段中，将控制电压信号的幅值降低至预设最大负压值，再将控制电压信号的幅值提升，以使目标胶囊基于控制电压信号进行颜色显示，以完成一帧的刷新，或者，
在与第一帧对应的时段中，将控制电压信号的幅值降低至预设最大负压值，再将控制电压信号的幅值提升，以使目标胶囊基于控制电压信号进行颜色显示，以完成第一帧的刷新，而在与第二帧对应的时段中，将控制电压信号的幅值提升至预设最大正压值，再将控制电压信号的幅值提升，以使目标胶囊基于控制电压信号进行颜色显示，以完成一帧的刷新。
具体地，在预设时段有且仅包括第一帧所对应的时段和第二帧所对应的时段时，可在该两个时段中的任意一时段中执行一次正压刷新流程以完成相应一帧的刷新，并在另一时段中执行一次负压刷新流程，以完成相应另一帧的刷新。其中，完成正压刷新流程的时段可以是上述第一帧所对应的时段，也可以是上述第二帧所对应的时段，此处不作限定。
基于上述方式，能够使目标胶囊在任意的相邻两帧所对应的时段中，分别执行一次正压刷新流程和一次负压刷新流程，也即使目标胶囊在任意的相邻两帧所对应的时段中分别接收一次正压的控制电压信号和依次负压的控制电压信号，使得目标胶囊能够持续保持所接收的控制电压信号的幅值抵达最大正压值和最大负压值的次数相等或相差一的状态，使得电子墨水屏中的电子墨水胶囊受到损伤的可能性降低，改善了电子墨水屏的显示效果。
在一实施例中，预设时段包括第一时段和第二时段，第一时段的时长与第二时段的时长之间的差值不大于预设时差阈值。
步骤S11具体可包括：
在第一时段中，基于正压刷新流程控制目标胶囊进行每一帧的颜色显示。在第二时段中，基于负压刷新流程控制目标胶囊进行每一帧的颜色显示。
具体地，可在第一时段中的每一帧所对应的时段中，均基于正压刷新流程，使目标胶囊所接收的控制电压信号的幅值先提升至预设最大正压值再降低至目标电压值，以进行相应的颜色显示，并在第二时段中的每一帧所对应的时段中，均基于负压刷新流程，使目标胶囊所接收的控制电压信号的幅值先降低至预设最大负压值再提升至目标电压值，以进行相应的颜色显示。
由于预设时段中每一帧所对应的时段的时长均相同或相近，而第一时段所对应的时长和第二时段所对应的时长之间的差值不大于预设时差阈值，能够使第一时段内的目标胶囊接收正电压和负电压的控制电压信号的次数相近或相等，进而使得电子墨 水屏中的电子墨水胶囊受到损伤的可能性降低，改善了电子墨水屏的显示效果。
可选地，第一时段内的帧数与第二时段内的帧数相等，且第一时段内的帧数或第二时段内的帧数大于一。
基于上述方式，能够使第一时段内，目标胶囊接收正电压和负电压的控制电压信号的次数相等，进而使得电子墨水屏中的电子墨水胶囊受到损伤的可能性最小化，改善了电子墨水屏的显示效果。
在一实施例中，预设时段包括第一时段和第二时段，第一时段所对应的时段内的帧数与第二时段所对应的时段内的帧数相等，第一时段所对应的时段在第二时段所对应的时段。
步骤S11具体可包括：
基于第一时段中执行负压刷新流程的次数，确定第二时段中所需执行正压刷新流程的次数，记作正压次数，并基于第一时段中执行正压刷新流程的次数，确定第二时段中所需执行负压刷新流程的次数，记作负压次数。
在第二时段中，执行正压次数的正压刷新流程，和负压次数的负压刷新流程。
具体地，在第二时段中，可根据在第一时段中目标胶囊分别接收正压的控制电压信号和负压的控制电压信号以完成一帧的颜色显示的次数，确定第二时段中，为减小电子墨水屏中的电子墨水胶囊受到损伤的可能性，目标胶囊所需要分别接收正压的控制电压信号和负压的控制电压信号以完成一帧的颜色显示的次数，通过该方式能够使得目标胶囊在预设时段中总共接收的正压和负压的控制电压信号的次数相等，减缓了电子墨水屏中的残影现象，改善了电子墨水屏的显示效果。
可选地，步骤S11具体还可包括：
在第一时段内，在使目标胶囊基于控制电压信号进行颜色显示，以完成一帧的刷新时，确定预设最大负压值和预设最大正压值中与控制电压信号的当前幅值最接近的值，若最接近的值为预设最大负压值，则执行负压刷新流程，若最接近的值为预设最大正压值，则执行正压刷新流程，以完成下一帧的刷新。
具体地，在第一时段中，可在目标胶囊完成一帧的刷新后，根据目标胶囊在完成该帧刷新时控制电压信号的幅值，确定当前幅值分别与预设最大正压值和预设最大负压值之间的差值，并将预设最大正压值和预设最大负压值中所对应的该差值最小的值，确定为控制电压信号的幅值最接近的值。
在确定最接近的值为预设最大正压值时，可认为将当前的控制电压信号的幅值调整为预设最大正压值，比调整为预设最大负压值更快，因此，为使信号幅值的速度最快，可执行正压刷新流程，以完成下一帧的刷新。同理，在确定最接近的值为预设最大负压值时，可认为将当前的控制电压信号的幅值调整为预设最大负压值，比调整为预设最大正压值更快，因此，为使信号幅值的速度最快，可执行负压刷新流程，以完成下一帧的刷新。
基于上述方式，能够使第一时段中目标胶囊的刷新速度最快化，并使得，第二时段中仍能根据第一时段正压刷新流程和负压次数的执行次数确定所需要相应执行的正压刷新流程和负压刷新流程的执行次数，确保目标胶囊所对应的正压刷新流程和负压刷新流程的次数平衡，进而减缓了电子墨水屏中的残影现象，改善了电子墨水屏的显示效果。
进一步地，在第二时段中，执行正压次数的正压刷新流程，和负压次数的负压刷新流程，具体可包括：
在第二时段中，在使目标胶囊基于控制电压信号进行颜色显示，以完成一帧的刷新时，确定预设最大负压值和预设最大正压值中与控制电压信号的当前幅值最接近的值，若最接近的值为预设最大负压值，则执行负压刷新流程，若最接近的值为预设最大正压值，则执行正压刷新流程，以完成下一帧的刷新，直至在第二时段中执行正压刷新流程的次数达到正压次数或在第二时段中执行负压刷新流程的次数达到负压次数。
在第二时段中，若第二时段中执行正压刷新流程的次数达到正压次数，则基于负压刷新流程控制目标胶囊完成第二时段中尚未刷新的每一帧的刷新，若第二时段中执行负压刷新流程的次数达到负压次数，则基于正压刷新流程控制目标胶囊完成第二时段中尚未刷新的每一帧的刷新。
基于上述方式，能够进一步使得第二时段中的部分帧所对应的刷新速度最快化，并同时确保目标胶囊所对应的正压刷新流程和负压刷新流程的次数平衡，进而减缓了电子墨水屏中的残影现象，改善了电子墨水屏的显示效果。
在一实施例中，将预设差值阈值与在预设时段内的正压刷新流程的次数的比例记作第一比例，和/或，将预设差值阈值与在预设时段内的负压刷新流程的次数的比例记作第二比例。
第一比例不大于预设比例阈值，和/或，第二比例不大于预设比例阈值。
具体地，举例说明，假设预设比例阈值为0.1，若在预设时段内的正压刷新流程的次数为10次，则第一比例不大于0.1的含义具体为预设差值阈值不大于1次，同理，若在预设时段内的负压刷新流程的次数为20次，则第二比例不大于0.1的含义具体为预设差值阈值不大于2次，上述各数值仅为一示例，具体还可以是其它数值，此处不作限定。
基于上述方式，能够根据预设时段内的正压刷新流程的次数和/或负压刷新流程的次数的大小，对预设差值阈值进行适应性调整，避免预设差值阈值相对于预设时段内的正压刷新流程的次数和/或负压刷新流程的次数过大或过小，从而导致电子墨水胶囊在预设时段内接收正压和负压的次数相差过大的情况发生，进一步提高了上述控制方法的可靠性，以改善电子墨水屏的显示效果。
在一实施例中，预设时段的时长不大于预设数量帧对应的时长。
具体地，基于上述方式，能够避免预设时段的时长过长，导致预设时段内目标胶囊接收到持续正压或负压的时长过长而引发损伤的情况发生。
可选地，预设数量与目标胶囊的使用时长呈负相关关系。
具体地，目标胶囊的使用时长越长则目标胶囊因接收连续正压或负压而收到损伤的可能性越高，因此，可使预设数量与目标胶囊的使用时长呈负相关关系，进一步降低目标胶囊受损的可能性，改善电子墨水屏的显示效果。
可选地，将多个电子墨水胶囊中使用时长最大的一胶囊的使用时长记作目标使用时长。其中，预设数量与目标使用时长呈负相关关系。
具体地，可根据多个电子墨水胶囊的使用时长中最大的使用时长，也即根据目标使用时长，确定所有电子墨水胶囊所对应的上述预设数量，进一步降低目标胶囊受损的可能性，改善电子墨水屏的显示效果。
