触控组件294包括触控屏和触控芯片，触控屏中包括显示面板，用于显示图像，视频等。触控屏中还可以包括触控电路，用于接收用户的触控操作。触控芯片用于向触控屏输出周期性的驱动信号，并从触控屏接收检测信号，当用户对触控屏进行触控操作时，检测信号发生变化。在一些实施方式中，终端设备200可以包括一个或多个触控组件294。在另一些实施方式中，触控组件294中的触控屏可以为折叠屏。
示例性的，如图2和图3中所示，触控屏的显示面板可以包括第一触控区域31和第二触控区域32，当触控屏进行折叠时，第一触控区域31和第二触控区域32可以位于不同平面，其中，图2中的触控屏向外折叠，使得折叠后第一触控区域31和第二触控区域32对用户可见，用户仍可以对触控屏进行触控操作，图3中的触控屏向内折叠，使得完全折叠后第一触控区域31和第二触控区域32相对，有利于保护触控屏的显示面板。本申请实施例提供的触控屏可以为图2所示的向外折叠的折叠屏，还可以应用于图3所示的向内折叠的折叠屏。
如图4所示，以触控屏为电容屏为例，触控屏的触控电路包括多个驱动(drive，DRV)电极41和多个检测(sense，SEN)电极42，多个驱动电极41与多个检测电极42交叉分布，多个驱动电极41与多个检测电极42之间无电连接，从而在每个交叉点形成电容形式的触控点43。多个驱动电极41分别输入来自触控芯片的周期性的驱动信号(例如正弦波或方波)，不同驱动电极41输入驱动信号相当于在横轴坐标上扫描触控操作的位置。由于人体是良导体，当用户的手指点击触控屏的某一位置(即产生触控操作)时，手指会与触控屏形成耦合电容从而改变该位置的触控点43的电容值，该触控点43对应的检测电极42向触控芯片输出的检测信号(电压或电流)相应发生改变，相当于在纵轴坐标上确定触控操作的位置。即通过触控点43的电容值的变化识别触摸操作的横纵坐标。
当图2所示的向外折叠的触控屏进行折叠后，一侧显示面板可以不显示内容，但是该侧的触控区域(例如第二触控区域32)仍处于有效状态，检测电极仍会检测到该触控区域的噪声，并且手掌或手指在该触控区域的操作也成为了噪声。另外，随着触控屏的尺寸不断增大，检测电极的长度增加，导致触控屏的检测电极输出的噪声也成倍增加，使得触控屏的信噪比(有效信号与噪声之比)降低，从而影响触控屏的触控性能，有可能产生误触控操作。
为此，本申请实施例将触控屏中的触控电路分成多个触控电路，每个触控电路包括独立的驱动电极和检测电极，降低单个触控电路中驱动电极的长度，从而降低触控屏的检测电极输出的噪声。
如图5和图6所示，本申请实施例提供的触控组件包括触控屏51和触控芯片52。
其中，触控屏51包括显示面板(图中未示出)和N个触控电路511，N为大于1的整数，显示面板包括N个触控区域，每个触控电路511位于一个触控区域。每个触控电路511包括多个驱动电极5111和多个检测电极5112，不同触控电路511包括的驱动电极5111的数目可以相同或不同，不同触控电路511包括的检测电极5112的数目可以相同或不同，本申请实施例中，以触控电路511包括b个驱动电极5111(例如DRV11-DRV1b，DRVn1-DRVnb、DRVN1-DRVNb)和a个检测电极5112(例如SEN11-SEN1a，SENn1-SENna、SENN1-SENNa)为例，但并不意在限定于此。1≤n≤N，且n为整数，a、b为正整数。
在每个触控电路511中，多个驱动电极5111和多个检测电极5112之间无电连接地交叉分布于所在触控区域，从而在每个交叉点形成电容形式的触控点。本申请实施例中多个驱动电极5111沿横轴排列，多个检测电极5112沿纵轴排列，但并不意在限定于此，多个驱动电极5111也可以沿纵轴排列，多个检测电极5112也可以沿横轴排列。属于不同触控电路511的多个驱动电极5111之间无电连接，并独立电连接至触控芯片52，使得属于不同触控电路511的多个驱动电极5111之间电气隔离。属于不同触控电路511的检测电极5112之间无电连接，并独立电连接至触控芯片52，使得属于不同触控电路511的多个检测电极5112之间电气隔离。即使得各个触控电路511之间是相互独立的。
触控芯片52包括控制电路521、N组驱动管脚522、N组检测管脚523和多个模拟前端(analog front end，AFE)电路524。N组驱动管脚522分别电连接至N个触控电路511的驱动电极5111(每组驱动管脚522电连接至一个触控电路511的驱动电极5111)，N组检测管脚523分别电连接至N个触控电路511的检测电极5112(每组检测管脚523电连接至一个触控电路511的检测电极5112)。N组检测管脚523还电连接至多个模拟前端电路524的输入端。
可选的，如图6所示，触控芯片52还包括多个选择开关525。N组检测管脚523通过多个选择开关525电连接至多个模拟前端电路524的输入端。受控于控制电路521，多个选择开关525可以选择一组检测管脚523电连接至多个模拟前端电路524的输入端，从而实现分时复用模拟前端电路524，降低模拟前端电路524的数量，降低触控芯片52的成本，减小触控芯片52的面积。
下面对触控屏51和触控芯片52的工作原理进行说明。
触控屏51包括N个触控电路511，在每个检测周期内，触控芯片52向一个触控电路511输出驱动信号，并检测该触控电路511输出的检测信号，所以共需要N个检测周期完成对整个触控屏51的触控操作的检测。
在第n(1≤n≤N，且n为整数)个检测周期内，触控芯片52的控制电路521通过N组驱动管脚522中的第n组驱动管脚，向触控51屏的第n个触控电路511的多个驱动电极5111分别输出周期性的驱动信号(例如正弦波或方波)，控制电路521可以采用轮询的方式依次向第n个触控电路511的多个驱动电极5111分别输出驱动信号，以实现在横轴坐标上扫描触控操作的位置。
当用户的手指未点击第n个触控电路511所在触控区域的任一位置时，第n个触控电路511的多个检测电极512向触控芯片52的N组检测管脚523中的第n组检测管脚输出的检测信号(电压或电流)相同。由于人体是良导体，当用户的手指点击第n个触控电路511所在触控区域的任一位置时，手指会与触控屏形成耦合电容从而改变该位置的触控点的电容值，该触控点对应的检测电极512输出的检测信号(电压或电流)相应发生改变，触控芯片52的多个模拟前端电路524对输入的检测信号进行模数转换得到数字信号，终端设备的处理器根据该数字信号可以确定触控操作对应哪个检测电极512，相当于在纵轴坐标上确定触控操作的位置，再结合在横轴坐标上扫描触控操作的位置，即可以确定触控操作的横纵坐标的位置。
可选的，对于图6中触控芯片52还包括多个选择开关525来说，在第n个检测周期内，控制电路521还可以控制多个选择开关525选择第n组检测管脚电连接至多个模拟前端电路524的输入端。使得多个模拟前端电路524能够对第n组检测管脚输入的检测信号进行模数转换得到数字信号。
下面以代表性的触控屏包括两个触控电路为例对触控组件进行说明。
如图7和图8所示，触控屏71可以包括第一触控电路711和第二触控电路712，第一触控电路711包括多个驱动电极7111(例如DRV11-DRV1b)和多个检测电极7112(例如SEN11-SEN1a)，第二触控电路712包括多个驱动电极7121(例如DRV21-DRV2b和多个检测电极7122(例如SEN21-SEN2a)。第一触控电路711的多个检测电极7111与第二触控电路712的多个检测电极7112独立电连接至触控芯片72；第一触控电路711的多个驱动电极7111与第二触控电路712的多个驱动电极7121之间电气隔离，并且独立电连接至触控芯片72。
触控芯片72包括第一组驱动管脚721、第二组驱动管脚722、第一组检测管脚723、第二组检测管脚724、控制电路725和多个模拟前端电路726。第一组驱动管脚721电连接至第一触控电路711的多个驱动电极7111，第一组检测管脚723电连接至第一触控电路711的多个检测电极7112；第二组驱动管脚722电连接至第二触控电路712的多个驱动电极7121，第二组检测管脚724电连接至第二触控电路712的多个检测电极7122。
触控芯片72在第一检测周期通过第一组驱动管脚721向第一触控电路711的多个驱动电极7111输出驱动信号，通过第一组检测管脚723从第一触控电路711的多个检测电极7112接收第一检测信号，第一检测信号用于对第一触控电路711所在第一触控区域的触控操作进行检测。触控芯片在第二检测周期通过第二组驱动管脚722向第二 触控电路的多个驱动电极输出驱动信号，通过第二组检测管脚724从第二触控电路712的多个检测电极7112接收第二检测信号，第二检测信号用于对第一触控电路711所在第二触控区域的触控操作进行检测。
多个模拟前端电路726用于对第一检测信号和或第二检测信号进行模数转换。
可选的，如图8所示，触控芯片72还包括多个选择开关727，控制电路725控制多个选择开关727选择第一组检测管脚或第二组检测管脚电连接至多个模拟前端电路的输入端。
如图9所示，第一触控电路711可以位于触控屏的显示面板的第一触控区域73，第二触控电路712位于触控屏的显示面板的第二触控区域74。特别地，当触控屏为沿折叠线75进行折叠的折叠屏时，第一触控区域73和第二触控区域74可以位于折叠线75两侧，即第一触控电路711和第二触控电路712可以位于折叠线75两侧。
在触控屏折叠后，当第一触控电路711在第一触控区域73检测用户的触控操作时，第二触控电路712可以处于失效状态，即第二触控电路712不在第二触控区域74检测用户的触控操作，手掌或手指在第二触控区域74的操作不会成为噪声，因此可以降低触控屏输出的噪声。
本申请实施例提供的触控组件，不仅适用于中大触控屏(例如平板电脑、笔记本电脑等的触控屏)以及折叠屏(例如折叠手机的触控屏)，制造成本低。并且由于通过将触控电路分成多个，每个触控电路具有独立的检测电极和驱动电极，降低了单个触控电路中检测电极的长度，检测电极的负载以及产生的噪声成倍降低，使得触控屏的信噪比(有效信号与噪声之比)大幅提高，从而提高触控屏的触控性能。
