Description

一种触摸面板的抗干扰方法及装置 技术领域
本发明涉及通信领域，尤其涉及一种触摸面板的抗干扰方法及装置。
背景技术
触摸面板(Touch Panel，TP)是一种能够接收触摸等方式输入的讯号的感应式液晶显示装置，通常设置于各种电子设备上。TP能够取代机械式的按钮面板，并借由液晶显示画面产生出生动的影音效果，大大提高了用户操作电子设备的效率。
在通过充电适配器对设置有TP的电子设备进行充电时，充电适配器与电子设备连接，此时，若TP处于工作状态，充电适配器的共模噪声可能会对TP产生干扰，影响TP的正常工作，因此需要调整TP的工作频点，使TP工作在噪声比较小的频段内。现有的TP的抗干扰方法为：TP首先获取充电适配器的共模噪声，并判断TP当前的工作频点的共模噪声的幅度是否大于或者等于预设阈值，其中，充电适配器的共模噪声的大小会对TP产生不同程度的干扰。若TP当前的工作频点的共模噪声的幅度大于或者等于预设阈值，则说明充电适配器的共模噪声可能会影响TP的正常工作，因此TP需要调整自身的工作频点。
然而，在现有的TP的抗干扰方法中，TP在调整自身的工作频点时只能从预设的工作频点或者预设的工作频段中选择噪声最小的工作频点，从预设的工作频点或者预设的工作频段中选择噪声最小的工作频点并不一定是共模噪声小的工作频点。
发明内容

此外，本申请的说明书和权利要求书及附图中的术语“第一”和“第二”等是用于区别不同对象，而不是用于限定特定顺序。
本发明实施例提供的技术方案可以应用于为各种设置有TP的电子设备充电的场景中。当充电适配器为电子设备充电时，充电适配器与电子设备可以通过数据线连接，充电适配器或者电子设备的内部设置有TP的抗干扰装置。
本发明实施例中，充电适配器或电子设备获取在当前充电适配器产生的共模噪声的强度，然后判断获取到的共模噪声的强度是否大于或等于预设阈值，当确定出共模噪声的强度大于或等于预设阈值时，TP的抗干扰装置根据充电适配器的工作频率和充电适配器的抖动频率计算得到触摸面板工作的低噪区间或低噪频点，低噪区间或低噪频点用以调整触摸面板的工作频率，以使得触摸面板工作在充电适配器新产生的共模噪声的强度小于预设阈值的频点上。
在TP的抗干扰装置设置在充电适配器中的情况下，TP的抗干扰装置在根据充电适配器的工作频率和充电适配器的抖动频率计算得到触摸面板工作的低噪区间或低噪频点后，能够将其发送至电子设备，以使得电子设备的TP根据低噪区间或低噪频点选择性切换自身的工作频点；在TP的抗干扰装置设置在电子设备中的情况下，TP的抗干扰装置可以接收充电适配器发送的充电适配器的工作频率和充电适配器的抖动频率，从而根据充电适配器的工作频率和充电适配器的抖动频率，计算触摸面板工作的低噪区间，并从低噪区间中选择低噪频点，以供实现电子设备的TP选择性切换自身工作的频点。

示例性的，以电子设备为智能手机为例，对智能手机的通用硬件架构进行说明。如图1所示，智能手机100包括：射频(Radio Frequency，RF)电路110、存储器120、其他输入设备130、显示屏140、传感器150、音频电路160、I/O子***170、处理器180、以及电源190等部件。本领域技术人员可以理解，图1所示的智能手机100的结构并不构成对手机的限定，可以包括比图示更多或者更少的部件，或者组合某些部件，或者拆分某些部件，或者不同的部件布置。本领域技术人员可以理解显示屏140属于用户界面(UI，User Interface)，且智能手机100可以包括比图示更多或者更少的部件。

本发明下述实施例中所提到的触摸面板通常为图1所示的触摸面板142，也可以为集成有触摸面板142功能的其他装置，本发明对此不作限制。
实施例1
本发明实施例提供一种触摸面板的抗干扰方法，在第一种可能的实现方式中，触摸面板的抗干扰装置设置在电子设备中，如图2所示，该方法包括S101和S102：
S101、触摸面板的抗干扰装置获取充电适配器的工作频率和充 电适配器的抖动频率。
可以理解的是，本发明实施例所提到的充电适配器的工作频率是指充电适配器的开关芯片的工作频率，充电适配器的抖动频率是指充电适配器的开关芯片的抖动频率。
具体的，如图3所示，步骤S101可以包括S101a：
S101a、触摸面板的抗干扰装置接收充电适配器发送的充电适配器的工作频率和充电适配器的抖动频率。
由于触摸面板的抗干扰装置设置在电子设备中，因此触摸面板的抗干扰装置可以接收充电适配器主动上报的充电适配器的工作频率和充电适配器的抖动频率；触摸面板的抗干扰装置也可以向充电适配器发送请求消息，使得充电适配器根据请求消息，发送充电适配器的工作频率和充电适配器的抖动频率至触摸面板的抗干扰装置。
S102、触摸面板的抗干扰装置根据工作频率和抖动频率，利用预设算法，计算触摸面板工作的低噪区间，以使得触摸面板获取低噪区间，并在触摸面板受到的干扰超过预设范围时切换触摸面板的工作频率到低噪区间中。
其中，低噪区间为触摸面板受到的干扰在预设范围内的触摸面板工作的频率区间，且低噪区间为多个连续或者离散的工作频点的集合；低噪频点为低噪区间所包含的所有频点中的任意一个频点。可以理解的是，用户可以根据实际需求对预设范围进行设定，本发明对此不作限制。
需要说明的是，本发明实施例所提到的充电适配器可以工作在不同的工作模式，例如固定频率与抖频模式和波谷导通模式。
示例性的，充电适配器工作在固定频率与抖频模式下，如图4所示，步骤S102可以包括S102a：
S102a、触摸面板的抗干扰装置根据充电适配器的工作频率和充电适配器的抖动频率，利用第一公式，计算触摸面板工作的低噪区间，其中，第一公式为wp＝f-(2n+1)△f，wp为触摸面板工作的低噪区间，f为充电适配器的工作频率，△f为充电适配器的抖动频率，n为 正整数。
可以理解的是，如图5所示，为充电适配器工作在固定频率与抖频模式下的频率与噪声的关系图。其中，图中水平方向的虚线表示预设范围，触摸面板工作的低噪区间为处于虚线下方的多个工作频点的集合。
从图5可以看出，触摸面板工作的低噪区间可以通过第一公式计算，即：
wp＝(n+1)(f-△f)-n(f+△f)
＝nf+f-n△f-△f-nf-n△f
＝f-(2n+1)△f
其中，wp为触摸面板工作的低噪区间，f为充电适配器的工作频率，△f为充电适配器的抖动频率，n为正整数。
又示例性的，充电适配器工作在波谷导通模式下，如图6所示，步骤S102可以包括S102b：
S102b、触摸面板的抗干扰装置根据充电适配器的工作频率和充电适配器的抖动频率，利用第二公式，计算触摸面板工作的低噪区间，其中，第二公式为wp＝f-(n+1)△f，wp为触摸面板工作的低噪区间，f为充电适配器的工作频率，△f为充电适配器的抖动频率，n为正整数。
可以理解的是，如图7所示，为充电适配器工作在波谷导通模式下的频率与噪声的关系图。其中，图中水平方向的虚线表示预设范围，触摸面板工作的低噪区间为处于虚线下方的多个工作频点的集合。
从图7可以看出，触摸面板工作的低噪区间可以通过第二公式计算，即：
wp＝(n+1)(f-△f)-nf
＝nf+f-n△f-△f-nf
＝f-(n+1)△f
其中，wp为触摸面板工作的低噪区间，f为充电适配器的工作 频率，△f为充电适配器的抖动频率，n为正整数。
还需要补充的是，通过本发明实施例所提到的计算触摸面板工作的低噪区间的方法，由于n为任意的正整数，因此，计算出的触摸面板工作的低噪区间可以为多个离散的频段，下述触摸面板的抗干扰装置从低噪区间中选择触摸面板工作的低噪频点时可以从其中一个频段中选择，也可以从不同的频段中选择，本发明对此不做限制。当然可以理解的是，触摸面板的抗干扰装置从低噪区间中选择触摸面板工作的低噪频点时一定要考虑触摸面板的工作频段，即触摸面板的抗干扰装置从低噪区间中选择出的触摸面板工作的低噪频点一定位于触摸面板的工作频段内。
可选地，由触摸面板自己还可以在低噪区间中选择出进行切换的低噪频点，同时，触摸面板在选择时同样要考虑自身的工作频段，即触摸面板选出位于触摸面板的工作频段内的低噪区间和/或低噪频点。又可选的，触摸面板的抗干扰装置在计算低噪区间时，能够考虑触摸面板的工作频段，即触摸面板的抗干扰装置事先确定好n的取值。
可选的，本发明实施例提供的触摸面板的抗干扰方法还可以包括步骤S103：
S103、触摸面板的抗干扰装置从低噪区间中选择触摸面板工作的低噪频点。
需要说明的是，触摸面板工作的低噪频点可以是低噪区间中的任意一个频点。触摸面板的抗干扰装置从低噪区间中选择触摸面板工作的低噪频点的步骤能够节省触摸面板选择低噪频点的时间。优选地，触摸面板的抗干扰装置可以选择低噪区间中充电适配器的工模噪声对触摸面板干扰最小的频点作为触摸面板工作的低噪频点，本发明对比不做限制。
本发明实施例提供的触摸面板的抗干扰方法，由于触摸面板的抗干扰装置能够获取充电适配器的工作频率和充电适配器的抖动频率，并根据充电适配器的工作频率和充电适配器的抖动频率计算触 摸面板工作的低噪区间，从而从低噪区间中选择触摸面板工作的低噪频点。与传统的调整TP的工作频点的方法相比，由于低噪区间和/或低噪频点是通过充电适配器的工作频率和充电适配器的抖动频率计算得到，因此使得触摸面板在当前工作频点的共模噪声的幅度过大时，直接将自身的工作频点跳转到低噪区间内的低噪频点上，从而提升触摸面板切换工作频点的准确性。
在第二种可能的实现方式中，触摸面板的抗干扰装置设置在充电适配器中，如图8所示，该方法包括：
S201、触摸面板的抗干扰装置获取充电适配器的工作频率和充电适配器的抖动频率。
S202、触摸面板的抗干扰装置根据工作频率和抖动频率，计算触摸面板工作的低噪区间。
S203、触摸面板的抗干扰装置从低噪区间中选择触摸面板工作的低噪频点。
具体的，步骤S201-S203的具体实现方式已经在步骤S101-S103中进行了详细描述，为了简洁，此处不再赘述。同时，步骤S201与步骤S101不同的是，由于触摸面板的抗干扰装置设置在充电适配器中，因此，触摸面板的抗干扰装置和充电适配器之间无需再进行数据的发送和接收过程，触摸面板的抗干扰装置直接从充电适配器内读取充电适配器的工作频率和充电适配器的抖动频率即可。
进一步地，如图9所示，该方法还包括步骤S204：
S204、触摸面板的抗干扰装置发送低噪区间，或者低噪频点，或者低噪区间和低噪频点至触摸面板。
由于触摸面板的抗干扰装置设置在充电适配器中，因此触摸面板的抗干扰装置在获取到低噪区间和/或低噪频点后，需要发送低噪区间和/或低噪频点至触摸面板，以使得触摸面板根据低噪区间和低噪频点，调整自身的工作频点。具体地，可以发送至电子设备，有电子设备内部通信接口传递给触摸面板。
需要说明的是，若触摸面板的抗干扰装置只发送低噪区间至触 摸面板，则无须执行步骤S203，触摸面板的抗干扰装置在执行完步骤S202后，发送低噪区间至触摸面板后，触摸面板能够自行从低噪区间中选择低噪频点；若触摸面板的抗干扰装置发送低噪频点，或者低噪区间和低噪频点至电子设备，则节省了触摸面板选择低噪频点的时间。
上述实施例中，在触摸面板的抗干扰装置获取充电适配器的工作频率和充电适配器的抖动频率之前，触摸面板的抗干扰方法还可以包括：触摸面板的抗干扰装置获取在当前充电适配器产生的共模噪声的强度，并判断获取到的共模噪声的强度是否大于或等于预设阈值。当确定出共模噪声的强度大于或等于预设阈值时，触摸面板的抗干扰装置根据充电适配器的工作频率和充电适配器的抖动频率计算得到触摸面板工作的低噪区间或低噪频点。
或者，触摸面板的抗干扰装置将低噪区间和/或低噪频点发给触摸面板后，当触摸面板判断自身当前的工作频点上共模噪声的强度大于或等于预设阈值时，将触摸面板的工作频点切换到低噪区间中或低噪频点上。
本发明实施例提供一种触摸面板的抗干扰方法，通过获取充电适配器的工作频率和充电适配器的抖动频率；根据工作频率和抖动频率，计算触摸面板工作的低噪区间；从低噪区间中选择触摸面板工作的低噪频点。与传统的调整TP的工作频点的方法相比，由于低噪区间和/或低噪频点是通过充电适配器的工作频率和充电适配器的抖动频率计算得到的，因此使得触摸面板在当前工作频点的共模噪声的幅度过大时，直接将自身的工作频点跳转到低噪区间内的低噪频点上，从而提升触摸面板切换工作频点准确性。
