随着多媒体技术的发展，智能交互平板等双系统电子设备由于具备人机交互功能，即通过触控技术供用户对显示界面中的内容进行操控来实现人机交互操作，逐渐替代传统的投影机、电视机以及视频会议终端等并被广泛应用，尤其是在教育教学、企业会议以及商业展示等领域。
其中，双系统电子设备设置有两个操作系统，即第一系统和第二系统，例如，第一系统可以是安卓系统且第二系统为Windows系统等。但是，目前双系统电子设备在第二系统下接收到用户输入的书写操作情况下，第二系统通常需要对书写操作的信号进行高清晰度多媒体接口(High Definition Multimedia Interface，HDMI)编码、传输以及HDMI解码等处理后，才能将书写操作对应的笔迹显示，整个过程繁琐且费时，从而使得双系统电子设备在第二系统下书写的效率较低。

本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象，而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施，且“第一”、“第二”等所区分的对象通常为一类，并不限定对象的个数，例如第一书写操作可以是一个，也可以是多个。此外，说明书以及权利要求中“和/或”表示所连接对象的至少其中之一，字符“/”，一般表示前后关联对象是一种“或”的关系。
下面结合附图，通过具体地实施例及其应用场景对本申请实施例提供的笔迹的显示方法进行详细地说明。
请参见图1，本申请实施例提供一种笔迹的显示方法，该笔迹的显示方法应用于双系统电子设备，如图1所示，方法包括如下步骤：
步骤101、在双系统电子设备的第二系统的显示界面中接收到输入第一书写操作的过程中，响应于第一书写操作，在第一系统的第一图层和第二图层，分别显示相叠设的第一笔迹和第二笔迹，其中，第二系统生成笔迹的速度比第一系统生成笔迹的速度慢，第一笔迹为第一系统生成的笔迹，第二笔迹为第二系统生成的笔迹；
步骤102、在检测到第一延时擦除事件触发的情况下，确定第一延时擦除事件是否满足预设延时擦除条件，其中，第一延时擦除事件为在第一书写操作的输入完成时触发的事件，且在第一延时擦除事件满足预设延时擦除条件的情况下，第二笔迹显示为第一笔迹的全部笔迹；
步骤103、在第一延时擦除事件满足预设延时擦除条件的情况下，将 第一笔迹擦除。
在本申请实施例中，在接收到在双系统电子设备的显示屏中输入第一书写操作的过程中，第一系统和第二系统可以分别将第一书写操作的笔迹显示与对应的图层，即第一系统对应的第一图层显示第一书写操作的第一笔迹，以及第二系统的第二图层显示第一书写操作的第二笔迹，且第一笔迹与第二笔迹相叠设，如此，通过本申请实施例，由于第一系统相比于第二系统具有更快的笔迹生成速度，通过第一系统实现对书写操作的笔迹加速显示，从而可以提升双系统电子设备在第二系统的显示界面下的书写效率；另外，在检测到第一书写操作完成时触发的第一延时擦除事件满足预设延时擦除条件的情况下，将第一笔迹擦除，此时第二图层显示的笔迹与第一图层显示的笔迹一致，从而能够避免双系统电子设备在擦除第一图层的笔迹时出现笔迹闪烁，进而提升笔迹的显示质量。
在上述步骤101中，若双系统电子设备的显示屏显示有第二系统的显示界面，则在接收到用户在第二系统的显示界面中输入的第一书写操作的过程中，双系统电子设备可以实现在第一图层显示由第一系统生成的第一笔迹，以及在第二图层显示由第二系统生成的第二笔迹，且第一笔迹与第二笔迹相互叠设。
需要说明的是，上述双系统电子设备包括显示屏、第一系统第二系统，显示屏用于显示第一系统或者第二系统的显示界面，以及，接收用户输入的操作(如书写操作等)；第一系统和第二系统可以理解为分别设置有不同操作系统的设备或者装置，第一系统和第二系统均设置有处理器以及存储器以实现独立运行。上述第一系统和第二系统的操作系统可以是包括Windows系统或者Android系统。
其中，在上述显示屏显示第二系统的显示界面的情况下，可以是在第一系统下将第二系统的显示界面以视频流的形式输出于显示屏，即第一系统为主系统，而第二系统为辅系统，例如，在Android系统运行的情况下，将Windows系统的显示界面以播放视频的方式在Android系统的显示界面中显示。
另外，上述双系统电子设备的第二系统为比第一系统具有更慢的笔迹 生成速度的装置或者设备，具体地，由于上述Windows系统相比Android系统具有更慢的笔迹生成速度，故上述第一系统可以是设置有Android系统的设备或者装置(后续简称“第一系统为Android系统”)，且上述第二系统可以是设置有Windows系统的设备或者装置(后续简称“第二系统为Windows系统”)。
本申请实施例中，上述响应于第一书写操作，在第一图层和第二图层，分别显示相叠设的第一笔迹和第二笔迹，可以是第一系统和第二系统分别获取第一书写操作的笔迹信息，通过笔迹信息计算得到上述第一笔迹和第二笔迹，且第一系统将其计算得到的第一笔迹在第一图层进行显示，而第二系统将其计算得到的第二笔迹在第二图层进行显示。
其中，上述第一图层和第二图层分别为第一系统的图层，第一图层用于显示第一系统的图像，第二图层用于显示第二系统的图像，且上述第一图层可以是透明覆盖于第二图层上，从而可以提升使用户无法感知第一图层，提升双系统电子设备的显示效果。
另外，上述第一系统和第二系统分别获取第一书写操作的笔迹信息，可以是在双系统电子设备的显示屏10在接收到第一书写操作的过程中，通过如下两种方式实现将接收到的第一书写操作的实时笔迹信息传输至第一系统和第二系统，具体如下：
方式一、显示屏10同时将第一书写操作的实时笔迹信息分别传输至第一系统11和第二系统12；
方式二、显示屏10将第一书写操作的实时笔迹信息传输至第一系统11，第一系统11再将接收到的实时笔迹信息转发至第二系统12。
可见，在方式一和方式二中，由于第二系统12比第一系统11具有更慢的生成笔迹的速度，那么，在第一系统11根据接收到的第一书写操作的所有笔迹信息生成第一笔迹并显示的情况下，此时第二系统12仍存在第一书写操作的部分笔迹信息未能计算出笔迹，从而导致在第一书写过程中，第二笔迹为第一笔迹的部分笔迹，即第一图层显示第一书写操作的全部笔迹时，第二图层对于第一书写操作最近输入的部分笔迹未能显示出。
在此，以第一系统为Android系统，第二系统为Windows系统为例， 在Windows系统显示界面书写“一”(即第一书写操作)时，在显示界面的Android系统对应的图层(即第一图层)显示“一”(即第一笔迹)，在Windows系统对应的图层(即第二图层)显示的是“一”的部分笔迹，例如，可以是四分之三的“一”，也可以是三分之二的“一”。
在上述步骤102中，在第一图层和第二图层分别显示第一书写操作过程中的第一笔迹和第二笔迹的情况下，当上述第一系统检测到上述第一书写操作完成时，第一系统触发第一延时擦除事件，并确定触发的第一延时擦除时间是否满足预设延迟擦除条件。
其中，上述第一系统检测到第一书写操作完成，可以是第一系统检测用户用于输入第一书写操作的手指或者书写笔等是否与显示屏分离，并在检测到手指或者书写笔与显示屏分离时，确认第一书写操作完成。
另外，上述预设延迟擦除条件可以基于第一系统当前的系统时间与触发上述第一延时擦除事件时第一系统的时间点(即第一书写操作完成时第一系统的时间点)之间的时长设置的条件，且在上述第一延时擦除事件满足上述预设延时擦除条件的情况下，上述第二笔迹显示为第一笔迹的全部笔迹，即此时第一书写操作最近书写的一段笔迹已在第二图层上显示。
本申请实施例中，由于第二系统相比第一系统生成笔迹存在延迟时间，那么第二图层显示与第一图层一致的笔迹会存在延时时间(在此简称“第二图层的笔迹延迟时长”)，因此，为保证第二图层显示第一图层一致的笔迹的情况下才擦除第一图层的第一笔迹，可以是在第一延时擦除时间触发时第一系统的时间点后经过一段时长再对第一笔迹进行擦除。
那么，可以是以第一延时擦除事件触发时第一系统的时间点后经过的时长设置上述预设延迟擦除条件。具体地，上述确定第一延时擦除事件是否满足预设延时擦除条件，可以包括：确定第一时间间隔的时长是否达到第一时长，其中，第一时间间隔为第一系统的系统时间与第一延时擦除事件触发时的的时间点之间的时间间隔；若第一时间间隔的时长达到第一时长，则确定上述第一延时擦除事件满足预设延时擦除条件；反之，则确定第一延时擦除事件不满足预设延时擦除条件。
本申请实施例中，上述第一时长可以根据第二图层的笔迹延迟时长来 确定，且该第一时长可以是预先设定的固定值。例如，可以将时长大于或者等于上述第二图层的笔迹延迟时长的预设时长作为上述第一时长。
需要说明的是，上述第一时长可以基于第二图层的笔迹延迟时长确定，可适当增加延迟时间，但延迟时间不宜过大，否则会造成第一系统的笔迹擦除不及时，如果用户在第一系统的笔迹擦除之前切换了第二系统的画面，没有及时擦除的第一笔迹会悬浮在屏幕上，对用户造成困惑。
或者，由于第二系统在不同场景下具有不同的运算速度，第二图层的笔迹延迟时长可能会存在波动，故上述第一时长也可以是上述第一系统基一段时间内的第二图层的笔迹延迟时长动态获取的时长。具体地，上述确定第一延时擦除事件是否满足预设延时擦除条件之前，还可以包括：
统计在第二时间间隔内的N个笔迹延迟时长，其中，N个笔迹延迟时长与N次历史书写操作对应，且笔迹延迟时长为第二图层显示所对应的历史书写操作的全部笔迹，相比于第一图层显示所对应的历史书写操作的全部笔迹存在的延迟时间，N为正整数；
基于N个笔迹延迟时长，确定第一时长。
这里，双系统电子设备可以根据一段时间内第二图层的笔迹延迟时长，确定上述第一时长，从而可以动态调节第一时长，且使确定的第一时长更合适，避免出现第一时长过长或者过短，进一步提升双系统电子设备的显示质量。
其中，上述第二时间间隔可以是时长预设且在接收到上述第一书写操作之前的时间间隔，具体地，上述第二时间间隔为第一时间点与接收到第一书写操作的第二时间点之间的时间间隔，第一时间点为在第二时间点之前的时间点，且第一时间点与第二时间点之间的时长为预设时长。
例如，可以是统计电子设备在接收到第一书写操作的前一天(即第二时间间隔)内的笔迹延迟时长。
需要说明的是，上述N个笔迹延迟时长中每一笔迹延迟时长，是第一系统对于上述第二时间间隔内的书写操作中，统计得到的第二图层相比于第一图层显示笔迹存在的延迟时长。
另外，上述基于第二时间间隔内的笔迹延迟时长，确定第一时长，可 以是按照预设的规则实现。具体地，N为大于1的整数；
基于N个笔迹延迟时长，确定第一时长，包括：
将N个笔迹延迟时长的平均值或者最高值，确定为第一时长。
这里，双系统电子设备可以将第二时间间隔内的多个笔迹延迟时长的平均值或者最高值确定为第一时长，使得确定第一时长的方式更灵活。
本申请实施例中，上述在检测到第一延时擦除事件触发的情况下，确定第一延时擦除事件是否满足预设延时擦除条件，还可以是通过其他方式实现，在此并不进行限定。具体地，第一书写操作为进行M次书写操作中的第M次书写操作，且M次书写操作中相邻两次书写操作之间的时间间隔小于或者等于第二时长，第一延时擦除事件为第M个延时擦除事件，M为大于1的整数；
在检测到第一延时擦除事件触发的情况下，确定第一延时擦除事件是否满足预设延时擦除条件，可以包括：
在检测到第M个延时擦除事件的情况下，启动定时器，并将第一笔迹添加至笔迹延迟擦除列表中，其中，第一笔迹为第M次书写操作的笔迹；
在定时器到达第二时长内，确定是否接收到在第二系统的显示界面中输入的第M+1次书写操作。
这里，第一系统可以根据第M次书写操作(即第一书写操作)书写完成时启动的定时器的定时时长(即第二时长)内是否接收到新的书写操作，确定第一延时擦除事件是否满足预设延时擦除条件，即在定时器的第二时长内未接收到第M+1次书写操作的情况下，确定第一延时擦除事件满足预设延时擦除条件；而在定时器的第二时长内接收到第M+1次书写操作的情况下，确定第一延时擦除事件不满足预设延时擦除条件。
例如，在用户完成书写“一”(即第一书写操作)时，双系统电子设备将“一”加入至笔迹延迟擦除列表中，并启动定时器，若定时器的第二时长内未接收到新的书写操作，则确定第一延时擦除事件满足上述预设延时擦除条件。
另外，若定时器到达第二时长之前确定接收到新的书写操作(即第M+1次书写操作)，则第一系统可以确定上述第一延时擦除事件不满足上 述预设延时擦除条件，此时，上述步骤102之后，还可以包括：若在定时器到第二时长内接收到第M+1次书写操作，则将第一书写操作更新为第M+1次书写操作，即重置并启动定时器，并将第M+1次书写操作的笔迹加入至笔迹延迟擦除列表中，且判断第M+1次书写操作完成时触发的延时擦除时间是否满足预设延时擦除条件。
这样，上述第一系统可以实现将新的书写操作的笔迹添加至笔迹延迟擦除列表，并重新判断新的书写操作完成时触发的第二延时擦除事件是否满足预设延时擦除条件，直至确定书写操作完成时触发的延时擦除事件满足预设延时擦除条。
例如，第一系统将“一”加入至笔迹延迟擦除列表之后，若在定时器的第二时长内接收到“一”上书写“丨”(即第M+1次书写操作)，如用户快速书写“十”字，则双系统电子设备将“丨”加入至笔迹延迟擦除列表，且重启确定时器，并判断在定时器的第二时长内是否接收到新的书写操作，若在定时器的第二时长内是否接收到新的书写操作，则确定第M+1次书写操作完成时触发的延时擦除事件满足上述预设延时擦除条件；否则，将新的书写操作的笔迹加入至至笔迹延迟擦除列表，且重启确定时器，直至确定新的书写操作完成时触发的延时擦除事件满足上述预设延时擦除条件。
在上述步骤103中，在确定第一延时擦除事件满足预设延时擦除条件之后，将第一系统可以将其第一图层上显示的第一笔迹擦除。
由上可知，上述确定第一延时擦除事件是否满足预设延时擦除条件，可以包括：
确定第一时间间隔的时长是否达到第一时长，其中，第一时间间隔为第一系统的系统时间与第一延时擦除事件触发的时间点之间的时间间隔；
那么，上述步骤103，可以包括：
在第一时间间隔的时长达到第一时长的情况下，将第一笔迹擦除。
这里，通过在第一书写操作完成之后的第一时长到达时擦除第一笔迹，从而不仅能够避免发生笔迹闪烁，还能使得擦除第一笔迹的实现方式更直观简单。
例如，在用户输入书写“一”的操作(即第一书写操作)的过程中，假设Windows系统的笔迹显示延迟时间为0.3毫秒，那么可以预设上述第一时长为0.4毫秒(即第一时长大于第二系统的笔迹显示延迟时间)，若双系统电子设备检测到书写“一”的操作完成，则Android系统在书写“一”的操作完成的时间点之后的0.4毫秒时擦除显示于第一图层的笔迹“一”。
或者，上述第一书写操作为进行M次书写操作中的第M次书写操作，第一延时擦除事件为第M个延时擦除事件，M为正整数；
步骤103，可以包括：
在检测到第M个延时擦除事件的情况下，启动定时器，并将第一笔迹添加至笔迹延迟擦除列表中，其中，第一笔迹为第M次书写操作的笔迹；
在定时器到达第二时长内，确定是否接收到在第二系统的显示界面中输入的第M+1次书写操作；
在第一延时擦除事件触发满足预设延时擦除条件的情况下，将第一笔迹擦除，包括：
若在定时器的第二时长内未接收到第M+1次书写操作，则将笔迹延迟擦除列表中的M次书写操作的笔迹擦除。
这里，第一系统可以根据第M次书写操作(即第一书写操作)书写完成时启动的定时器的定时时长(即第二时长)内是否接收到新的书写操作，确定是否对添加至笔迹延迟擦除列表中的M次书写操作的笔迹进行擦除，即在未接收到的新的书写操作的情况下，将M次书写操作的笔迹一次性擦除，从而使延时擦除笔迹的实现方式更多样。
需要说明的是，上述第一书写操作可以是连续多次书写操作(即M＝2)过程中的任意一次书写操作，而在连续多次书写操作过程中，由于多次书写操作的笔迹之间存在交叉，对于第一图层处于交叉位置的笔迹进行擦除，容易引起笔迹发生闪烁，而通过设置上述目标时长擦除每一次书写操作在第一图层的笔迹，虽然可以避免其他位置的笔迹出现闪烁，但交叉位置笔迹的可能仍然会出现闪烁，例如，在擦除前一次书写操作在第一图层的笔迹时，可能会将后一次书写操作在第一图层处于交叉位置的笔迹 擦除，而在擦除后第二图层又会延时显示后一次位于交叉位置的笔迹，引起笔迹闪烁。
而上述通过上述设置定时器和笔迹延迟擦除列表的方式，在上述第一书写操作为多次书写操作中最近一次书写操作(即M次书写操作的第M次书写操作)的情况下，第一系统可以根据第一书写操作书写完成时启动的定时器的定时时长内是否接收到新的书写操作，确定是否对多次书写操作的笔迹(即笔迹延迟擦除列表中的笔迹)进行擦除，即在未接收到的新的书写操作的情况下，将多次书写操作的笔迹一次性擦除，相比于在每次书写操作后进行笔迹擦除，可以避免比较交叉位置出现笔迹闪烁，进一步提升双系统电子设备的笔迹显示效果。
例如，在依次接收到上述书写“一”的操作(即第M-1次书写操作)和书写“丨”的操作(即第M次书写操作)的情况下，如用户快速书写“十”，双系统电子设备可以将笔迹“一”和笔迹“丨”加入至笔迹延迟擦除列表后，若在输入“丨”的书写操作完成时启动的定时器的第二时长内，未接受到新的书写操作，则第一系统将笔迹延迟擦除列表中的“一”和“丨”从第一图层上擦除。
需要说明的是，在上述定时器到达第二时长之前确定接收到新的书写操作(即第M+1次书写操作)，第一系统可以将新的书写操作的笔迹加入至笔迹延迟擦除列表，并重启定时器，以判断新的书写操作完成时触发的第二延时擦除事件是否满足预设延时擦除条件，直至确定书写操作完成时触发的延时擦除事件满足预设延时擦除条件，将笔迹延迟擦除列表的所有笔迹进行擦除，从而可以避免连续书写过程中出现的笔迹闪烁。
请参见图2，本申请实施例提供一种笔迹的显示装置，应用于双系统电子设备的第一系统，如图2所示，该笔迹的显示装置200包括：

延时擦除条件确定模块202，用于在检测到第一延时擦除事件触发的情况下，确定第一延时擦除事件是否满足预设延时擦除条件，其中，第一延时擦除事件为在第一书写操作的输入完成时触发的事件，且在第一延时擦除事件满足预设延时擦除条件的情况下，第二笔迹显示为第一笔迹的全部笔迹；
笔迹擦除模块203，用于在第一延时擦除事件满足预设延时擦除条件的情况下，将第一笔迹擦除。
基于此，在接收到在双系统电子设备的显示屏中输入第一书写操作的过程中，第一系统和第二系统可以分别将第一书写操作的笔迹显示与对应的图层，即第一系统对应的第一图层显示第一书写操作的第一笔迹，以及第二系统的第二图层显示第一书写操作的第二笔迹，且第一笔迹与第二笔迹相叠设，如此，通过本申请实施例，由于第一系统相比于第二系统具有更快的笔迹生成速度，通过第一系统实现对书写操作的笔迹加速显示，从而可以提升双系统电子设备在第二系统的显示界面下的书写效率；另外，在检测到第一书写操作完成时触发的第一延时擦除事满足预设延时擦除条件的情况下，将第一笔迹擦除，此时第二图层显示的笔迹与第一图层显示的笔迹一致，从而能够避免双系统电子设备在擦除第一图层的笔迹时出现笔迹闪烁，进而提升笔迹的显示质量。
可选的，延时擦除条件确定模块202，具体用于：
确定第一时间间隔的时长是否达到第一时长，其中，第一时间间隔为第一系统的系统时间与第一延时擦除事件触发的时间点之间的时间间隔；
笔迹擦除模块203，具体用于：
在第一时间间隔的时长达到第一时长的情况下，将第一笔迹擦除。
基于此，通过在第一书写操作完成之后的第一时长到达时擦除第一笔迹，从而不仅能够避免发生笔迹闪烁，还能使得擦除第一笔迹的实现方式更直观简单。
可选，装置200还包括：
时长统计模块，用于统计在第二时间间隔内的N个笔迹延迟时长，其中，N个笔迹延迟时长与N次历史书写操作对应，且笔迹延迟时长为第二 图层显示所对应的历史书写操作的全部笔迹，相比于第一图层显示所对应的历史书写操作的全部笔迹存在的延迟时间，N为正整数；
时长确定模块，用于基于N个笔迹延迟时长，确定第一时长。
基于此，笔迹的显示装置200可以根据一段时间内第二图层的笔迹延迟时长，确定上述第一时长，从而可以动态调节第一时长，且使确定的第一时长更合适，避免出现第一时长过长或者过短，进一步提升双系统电子设备的显示质量。
可选的，N为大于1的整数；
时长确定模块，具体用于：
将N个笔迹延迟时长的平均值或者最高值，确定为第一时长。
基于此，笔迹的显示装置200可以将第二时间间隔内的多个笔迹延迟时长的平均值或者最高值确定为第一时长，使得确定第一时长的方式更灵活。
可选的，第一书写操作为进行M次书写操作中的第M次书写操作，第一延时擦除事件为第M个延时擦除事件，M为正整数；
延时擦除条件确定模块202，包括：
定时单元，用于在检测到第M个延时擦除事件的情况下，启动定时器，并将第一笔迹添加至笔迹延迟擦除列表中，其中，第一笔迹为第M次书写操作的笔迹；
确定单元，用于在定时器到达第二时长内，确定是否接收到在第二系统的显示界面中输入的第M+1次书写操作；
笔迹擦除模块203，具体用于：
若在定时器的第二时长内未接收到第M+1次书写操作，则将笔迹延迟擦除列表中的M次书写操作的笔迹擦除。
基于此，第一系统可以根据第M次书写操作(即第一书写操作)书写完成时启动的定时器的定时时长(即第二时长)内是否接收到新的书写操作，确定是否对添加至笔迹延迟擦除列表中的M次书写操作的笔迹进行擦除，即在未接收到的新的书写操作的情况下，将M次书写操作的笔迹一次性擦除，从而使延时擦除笔迹的实现方式更多样。
