为了更清楚地说明本发明实施例中的技术方案，下面将对实施例中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动性的前提下，还可以根据这些附图获得其他的附图。

下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清 楚、完整地描述，显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
本发明的说明书和权利要求书及所述附图中的术语“第一”、“第二”等是用于区别不同对象，而不是用于描述特定顺序。此外，术语“包括”和“具有”以及它们任何变形，意图在于覆盖不排他的包含。例如包含了一系列步骤或单元的过程、方法、系统、产品或设备没有限定于已列出的步骤或单元，而是可选地还包括没有列出的步骤或单元，或可选地还包括对于这些过程、方法、产品或设备固有的其它步骤或单元。
在本文中提及“实施例”意味着，结合实施例描述的特定特征、结构或特性可以包含在本发明的至少一个实施例中。在说明书中的各个位置出现该短语并不一定均是指相同的实施例，也不是与其它实施例互斥的独立的或备选的实施例。本领域技术人员显式地和隐式地理解的是，本文所描述的实施例可以与其它实施例相结合。
请参阅图1，本发明第一实施例提供一种触控面板10，触控面板10包括辅助触控层200和触控层400，辅助触控层200用于响应触控面板10形变产生参考电容变化值。触控层400与辅助触控层200层叠且间隔设置，触控层400用于响应触控以及触摸面板10形变而产生电容变化值，触控层400产生的电容变化值与辅助触控层200产生的参考电容变化值的差值用于确定触控层400是否发生触控事件。
当触控面板10发生形变但没有被触控时，触控层400和辅助触控层200都会因为形变而产生电容变化，触控层400产生电容变化值后一般会发生响应，进而产生错误的触控信号，但事实上此时并没有触控；当触控面板10在发生形变的同时也被触控时，触控层400产生的电容变化值实际上是触控层400 被触控和因形变而造成的叠加后的电容变化值，如果叠加后的电容变化值用于确定触控层400的位置时会出现错误报点。因此在本发明中将触控层400因触控和形变产生的电容变化值与辅助触控层200因形变产生的参考电容变化值的差值用于确定触控层400是否确定是否发生触控事件，可以消除触控层400因为形变而产生的电容变化值，进而得到准确触控报点或者被触控的准确触控位置。
本发明提供的触控面板10能够消除因触控面板10形变产生的电容变化的影响，得到准确触控报点或者被触控的准确触控位置。
如图1所示，所述触控面板10还包括基板100和隔离层300，辅助触控层200设置在基板100的承载侧，隔离层300设置在辅助触控层200远离基板100的一侧，触控层400设置在隔离层300远离辅助触控层200的一侧。其中隔离层300用于将辅助触控层200和触控层400电性隔离，防止辅助触控层200和触控层400在工作时互相电性干扰，而影响触控层400产生的电容变化值和辅助触控层200产生的参考电容变化值的准确性。可以理解的是，当隔离层300为导电层时，隔离层300接地连接，防止具有导电性质的隔离层300对辅助触控层200造成影响。优选地，所述隔离层300采用电性绝缘材料制成。
在进一步的实施例中，触控层400响应触摸面板10形变产生的电容变化值与辅助触控层200响应触摸面板10发生的形变产生的参考电容变化值相等或者相差第一预设范围值。以使辅助触控层200用于辅助获得触控层400在形变时产生的电容变化值更准确。当相差第一预设范围值时，触控面板10可根据第一预设范围值矫正电容变化值或者参考电容变化值。
可以理解的是，触控层400与辅助触控层200在包括拉伸在内的形变过程中，两者中的电极面积、电极间距可以保持一致或者保持基本一致。在一些实施例中，触控层400和辅助触控层200的电极图案完全重叠一致。
在进一步的实施例中，触控面板10还包括处理器500，处理器500用于根据辅助触控层200产生的参考电容变化值和触控层400产生的电容变化值确定触控层400是否发生触控事件。可以理解的是，处理器500在接收到辅助触控层200产生的参考电容变化值和触控层400产生的电容变化值之后，通过计算辅助触控层200产生的参考电容变化值和触控层400产生的电容变化值的差值确定触控层400是否发生触控事件。
在一些实施例中，所述处理器500还在确定触控层发生触控事件时确定触控的位置信息，其中被触控时的位置信息可通过触控层400的产生电容变化值的触控电极来确定，例如，每个触控电极预先映射有对应的位置信息，所述处理器500在确定触控层400被触控时，则进一步确定触控的位置信息为产生电容变化值的电极所映射的位置信息。可以理解的是，处理器500与触控层400及辅助触控层200连接，以获取触控层400产生的电容变化值和辅助触控层200产生的参考电容变化值。
在进一步的实施例中，处理器500用于将触控层400产生的电容变化值减去辅助触控层200产生的参考电容变化值而得到一目标电容变化值，并根据目标电容变化值确定触控层400是否发生触控事件。当目标电容变化值大于等于预设电容值时，处理器500可以确定触控层400被触控，此时再根据产生电容变化值的触控电极来确定被触控时的位置信息。当目标电容变化值小于预设电容值时，处理器500可以确定触控层400没有被触控，处理器500控制触控层400不响应电容变化值，也就是说触控面板10此时不报点，不产生触控信号，也不进行确定被触控的位置信息，此时可以确定触控面板10是发生形变而不是被触控。
在进一步的实施例中，辅助触控层200与触控层400的初始电容值相等或者相差第二预设范围值。也就是说在未发生形变或者未发生触控时，辅助触控 层200与触控层400的初始电容值相等或者相差第二预设范围值，使得辅助触控层200在用于辅助获得触控层400在被触控时的位置信息更准确。可以理解的是，触控层400和辅助触控层200的电极图案完全重叠一致或者大致一致。
请参阅图2，在进一步的实施例中，触控层400为互电容式触控层，包括驱动电极层410和感应电极层420。驱动电极层410包括若干驱动电极411，感应电极层420包括若干感应电极421，感应电极421和驱动电极411共同用于响应触控以及触摸面板10形变而产生电容变化值。如图2所示，可将感应电极421设置在驱动电极411远离隔离层300的一侧，且感应电极421和驱动电极411排列方向相交，优选为绝缘垂直交叉。
在进一步的实施例中，辅助触控层200为互电容式触控层，包括辅助驱动电极层210和辅助感应电极层220。辅助驱动电极层210包括若干辅助驱动电极211，辅助感应电极层220包括若干辅助感应电极221，辅助感应电极221和辅助驱动电极211共同用于响应触摸面板10形变而产生参考电容变化值。将辅助触控层200与触控层400均设置为互电容式触控层，且设置成一样的电极图案，优选采用相同的电极材料，有利于获得更准确的触控位置信息。
请参阅图3，本发明第二实施例提供一种触控面板10a，在触控面板10a中，触控层400为自电容式触控层，包括若干触控电极430，每一触控电极430包括相对设置的第一端431和第二端432，若干触控电极430并排且首尾交错设置，每一触控电极430的第一端431与相邻的触控电极430的第二端432正对，且每一触控电极430的宽度自第一端431向第二端432逐渐减小。如图3所示，触控电极430可设置成三角形，可以理解的是，由于触控电极430从第一端431到第二端432的宽度不一致，因此当其被触控时会产生特定信号以用于确定其位置信息。
在进一步的实施例中，辅助触控层200为自电容式触控层，包括若干辅助 触控电极230，每一辅助触控电极230包括相对设置的第三端231和第四端232，若干辅助触控电极230并排且首尾交错设置，每一辅助触控电极230的第三端231与相邻的辅助触控电极230的第四端232正对，且每一辅助触控电极230的宽度自第三端231向第四端232逐渐减小。将辅助触控层200与触控层400均设置为自电容式触控层，且设置成一样的电极图案，优选采用相同的电极材料，有利于获得更准确的触控位置信息。优选的，每一辅助触控电极230在触控层400上的投影与对应的触控电极430重合。可以理解的是，在该实施例中，隔离层设置在辅助触控层200与触控层400之间，防止辅助触控层200和触控层400在工作时互相电性干扰，而影响触控层400产生的电容变化值和辅助触控层200产生的参考电容变化值的准确性。可以理解的是，当隔离层300为导电层时，隔离层300接地连接，防止具有导电性质的隔离层300对辅助触控层200造成影响。优选地，所述隔离层300采用电性绝缘材料制成。
请参阅图4，本发明第三实施例提供一种触控面板10b，在触控面板10b中还包括薄膜晶体管层600，薄膜晶体管层600设置在基板100和辅助触控层400之间。也就是说将辅助触控层200邻近薄膜晶体管层600设置或者设置在其一侧。薄膜晶体管层600可用于驱动触控层400或者辅助触控层200工作。当触控面板10b为触控显示面板时，薄膜晶体管600可以用于驱动触控显示面板发光。
请参阅图5，本发明第四实施例提供一种触控面板10c，在触控面板10c中，包括薄膜晶体管层600，薄膜晶体管层600设置在基板100的承载侧，辅助触控层200设置在薄膜晶体管层600中。可以理解的是，可通过印刷、光刻等工艺将辅助触控层200形成在薄膜晶体管层600中，以降低触控面板10c的厚度。
在进一步的实施例中，触控面板10c包括有源区11和非有源区12，薄膜 晶体管层600包括阵列分布的薄膜晶体管610，薄膜晶体管610设置在有源区11中，辅助触控层200设置在非有源区12中。将辅助触控层200设置在非有源区12，可以避免当薄膜晶体管610工作时对辅助触控层200的电性干扰。
请参阅图6，本发明第五实施例提供一种触控面板10d，在触控面板10d中，还包括发光功能层700，发光功能层700设置在基板100的承载侧，辅助触控层200设置在发光功能层700中。该实施例中的触控面板10d为触控显示面板，可以理解的是，可通过印刷、光刻等工艺将辅助触控层200形成在发光功能层700中，以降低触控面板10d的厚度。
请参阅图7，本发明还提供一种触控装置20，触控装置20包括上述任一项的触控面板10。触控装置20可以为但不仅限于为手写板、电子书、智能手机(如Android手机、iOS手机、Windows Phone手机等)、平板电脑、柔性掌上电脑、柔性笔记本电脑、移动互联网设备(MID，Mobile Internet Devices)或穿戴式设备等，或者可以为有机电致发光二极管(Organic light-emitting diodes，OLED)触控装置、有源矩阵有机发光二极管(Active Matrix Organic Light Emitting Diode，AMOLED)触控装置。

在进一步的实施例中，在“计算触控层400产生的电容变化值与辅助触控层200产生的参考电容变化值的差值”之前，触控面板10的控制方法还包括步骤S300和步骤S400。详细步骤介绍如下所述。

采用本实施例的控制方法可以消除触控层400因为形变而产生的电容变化值，进而得到准确触控报点或者被触控的准确触控位置。
