具体实施方式
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。
此外，以下各实施例的说明是参考附加的图示，用以例示本发明可用以实施的特定实施例。本发明中所提到的方向用语，例如，“上”、“下”、“前”、“后”、“左”、“右”、“内”、“外”、“侧面”等，仅是参考附加图式的方向，因此，使用的方向用语是为了更好、更清楚地说明及理解本发明，而不是指示或暗指所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本发明的限制。
在本发明的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸地连接，或者一体地连接；可以是机械连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本发明中的具体含义。

请参见图2，图2是本发明实施例提供的一种电容式触摸屏20的结构示意图，所述触摸屏20包括玻璃基板260和感测电路(图未标)，其中，所述感测电路包括第一引线231、第二引线232、第三引线233、信号输入通道221、222、223、224和信号输出通道211、212、213、214、215、216，且所述感测电路中的第一引线231、第二引线232和第三引线233布设于所述玻璃基板260上，以下是对各个模块的详细描述。可以理解的是，在本发明的其他实施例中，所述信号输入通道、信号输出通道及引线的数量并不局限于上述的数量，还可 以根据具体的实际需要设置为其他数量个。
所述第一引线231布设于所述玻璃基板260上。
具体地，该第一引线231由导电材料制作而成，具体可为但不限于Ag、Al等金属以及高分子导电化合物。为了保证屏幕光线的透射率，该导电材料可以具备透光性，例如，可将Al制作成厚度较小的铝片或铝箔，以透射光线。另外，布设于玻璃基板260上的第一引线231可以是通过电镀工艺镀上的。进一步地，所述第一引线231的数量不作具体限制，当第一引线231数量为多个时，相邻两条第一引线231可以是互相平行的，并且相邻两条第一引线231之间的距离可以为一个预设的固定值，或者一个预设的范围值，也即是说，多条第一引线231在所述玻璃基板260上均匀分布。在图2中，为了便于描述，只对其中的一条第一引线231进行了标号，显然，与已标号的第一引线231具有相同剖面的图形也属于第一引线。所述玻璃基板260的作用包括但不限于作为各种引线的支撑，该玻璃基板260在功能上可作为引线的依托，在性能上应具备透射性，此处不对该玻璃基板260所使用的材料作限制。
所述第二引线232布设于玻璃基板260上，第二引线232的数量为N条，其中，N为大于等于2的偶数，两条相邻的所述第二引线232互相平行，另外，该第二引线232与第一引线231绝缘且交叉。
具体地，为了与所述第三引线233加以区分，该第二引线232上标注有向上的箭头“▲”，应当理解的是，这些箭头的区分仅用于在理解本发明方案的时候对第二引线和第三引线进行区分，在实际的产品当中，不一定会呈现箭头所述的箭头。所述第二引线232可由导电材料制作而成，可为但不限于Ag、Al等金属以及高分子导电化合物。为了保证屏幕光线的透射率，该导电材料可以具备透光性，例如，由Al制成的第二引线232可制成厚度较小的铝片或铝箔，以透射光线。另外，布设于玻璃基板260上的第二引线232可以是通过电镀工艺镀上的。
进一步地，所述第二引线232的数量为N条，其中，N为大于等于2的偶数，并且该N条第二引线232中的任意两条第二引线232之间相互平行，任意两条相邻的第二引线232之间的距离为一个预设的固定值，或者为一预设的范围值，也即是说，N条第二引线232在玻璃基板上均匀分布。在图2中， 为了便于描述，只对其中的一条第二引线232进行了标号，显然，与已标注出的第二引线232具有相同箭头方向的线条也属于第二引线。
需要说明的是，虽然第二引线232和第一引线231同处玻璃基板260上且相互交叉，但是，第二引线232与第一引线231之间绝缘，在具体操作时，可在第一引线231与第二引线232相交的位置设置相应的桥接电路，具体地，连接于两个连接点236之间的第二引线232以该连接点236作为支撑，跨过与之相交的第一引线231，以保证第一引线231和第二引线232在均匀遍布玻璃基板260的同时，彼此之间绝缘，图2中，只对一个连接点236进行了标号，可以理解的是，其他具有相同剖面的图形也属于连接点236。另外，由于所述第二引线232与所述第一引线231相交的位置存在桥接，所以必定有一种引线呈凹凸状，但由于凹凸的程度较小，依然可视该凹凸状的引线为呈线性，并具备线性特征。
所述第三引线233布设于玻璃基板260上，第三引线233的数量为N条，该第三引线233分别与第二引线232和第一引线231之间绝缘，并与所述第一引线231相交叉。
具体地，为了与所述第二引线232加以区分，该第三引线233上标注有向下的箭头“▼”，可以理解的是，“▼”的使用仅用于协助理解本发明方案，不代表实际产品中具有“▼”。所述第三引线233由导电材料制作而成，可为但不限于Ag、Al等金属以及高分子导电化合物，为了保证屏幕光线的透射率，该导电材料可以具备透光性，例如，由Al制成的第三引线233可制成厚度较小的铝片或铝箔以透射光线，另外，布设于玻璃基板上的所述第三引线233可以是通过电镀工艺镀上的。
进一步地，所述第三引线233的数量为N条，更确切的说是遍布整个玻璃基板260，相邻两条第三引线233可以是互相平行的，并且相邻两条第三引线233之间的距离可以为一个预设的固定值，或者一个预设的范围值，也即是说，多条第三引线233在玻璃基板260上均匀分布，在图2中，为了方便描述，只对其中的一条第三引线233进行了标号，显然，与已标注出的一条第三引线233具有相同箭头方向的线条也属于第三引线。
所述玻璃基板260的作用包括但不限于作为各种引线的支撑，该玻璃基板 260在功能上可作为引线的依托，在性能上应具备透射性，此处不对该玻璃基板使用的材料作限制。
所述信号输入通道221、222、223、224分别连接至对应的所述第一引线231。
具体地，以信号输入通道224为例，该信号输入通道224用于向与之相连接的所述第一引线231传输脉冲信号TX4，具体地，该脉冲信号TX4可以是方波信号。需要说明的是，在图2中，221至224均为信号输入通道，每个信号输入通道均连接一条与之对应的第一引线231。
所述信号输出通道包括第二引线信号输出通道211、212、213、214和第三引线信号输出通道215、216。其中，每一条第三引线信号输出通道均连接N/2条第三引线233，每一条第三引线233连接一条第三引线信号输出通道，第二引线信号输出通道的数量为N/2，每一条第二引线信号输出通道连接2条第二引线232，且每一条第二引线232只与其中的一条第二引线信号输出通道相连接。
需要补充说明的是，以上都是在假设N为偶数的情况下展开描述的，在实际应用中，N还可以是奇数，当N为奇数时，权利要求书和说明书中的第三引线信号输出通道中，有一个第三引线信号输出通道连接(N+1)/2条第三引线233，另一个第三引线信号输出通道连接(N-1)/2条第三引线233，同时第二引线信号输出通道的数量为(N+1)/2。可以理解的是，在N为奇数时的感测电路设计与本申请所述的N为偶数时的感测电路设计相似，可由图2所示的电容式触摸屏推导获得，因此本发明的实施例虽然仅对当N为偶数的情况进行了详细说明，基于本发明的上述实施例，本领域普通技术人员在基于N为奇数时所获得的所有其他实施例，都属于本发明保护的范围。
具体地，信号输出通道可以包括第二引线信号输出通道211、212、213、214和第三引线信号输出通道215、216。第二引线信号输出通道的数量与第三引线信号输出通道的数量相关，由于第三引线信号输出通道为2条，因此第二引线信号输出通道的数量为将第二引线的数量进行平分为2份得到的数量，具体为N/2条，其中，所述第二引线信号输出通道与第二引线232相连接，具体地，每一条第二引线信号输出通道连接2条第二引线232，且每一条第二引线 232只与一条第二引线信号输出通道相连接。相应的，所述第三引线信号输出通道与所述第三引线233相连接，具体地，每一条第三引线信号输出通道连接N/2条第三引线233，且每一条第三引线233只与一条第三引线信号输出通道相连接。
以上是对一种电容式触摸屏的结构的描述，为了方便理解本发明方案的技术改进点，以下提供基于上述结构的应用实例，需要说明的是，该应用实例仅为一种可选的用于支撑本发明方案的例子，不用于限制本发明的保护范围。
步骤1、配置有触摸屏的终端通过信号输入通道向与该信号输入通道电性连接的第一引线231输入脉冲信号，更确切地说是方波信号。当有多条第一引线231时，每条第一引线231对应一个信号输出通道，终端通过信号输入通道输入方波信号时，是按照预设的时间间隔依次给各个信号输入通道输入方波信号(更确切的说是高电平信号)，相应地，各条第一引线轮流接收到方波信号，因此，终端可根据第一引线上的信号判断任意时刻由哪条信号输入通道输入脉冲信号。假设某一个时刻，从信号输入通道221输入了脉冲信号TX1，那么与信号输入通道221相连接的第一引线231接收到脉冲信号TX1，由于第一引线231与第二引线232绝缘但距离较近，并且与第三引线233绝缘但距离较近，因此，所述第一引线231与第二引线232之间会形成一个电容(为了方便后续描述取名为第一引线电容，如图3中的电容Cx)，所述第一引线231与第三引线233之间也会形成一个电容(为了方便后续描述取名为第二引线电容，类似于图3中的Cx)。当与所述信号输入通道221连接的第一引线231接收到脉冲信号后，会分别给第一引线电容和第二引线电容进行均匀充电，充电过程如图5所示。在图5中，稳定充电情况下，需要耗时t2-t1，即可将电压从1.7v充到1.8v。
步骤2、在信号输入通道221输入脉冲信号TX1时，触摸屏接收来自外界的触碰，通常情况是来自手指250(如图4所示)的触碰，但不排除其他形式的触碰，以图2所示的触碰点为例，当人体通过手指250触碰左点241时，人体与第一引线231之间也形成了电容(为了方便后续描述取名为等效电容，如图4中的Cg)，因此，在给所述第一引线电容和所述第二引线电容充电的同时，还需要给等效电容Cg充电，这势必会导致图6所示的情景，即给第一引线电 容Cx充电的参数会发生改变，起始电压将为1.6v，要充到饱和状态下的1.8v需要t3-t1的时间，(t3-t1)大于(t2-t1)，即充电时间增加。此外，第二引线电容充电的参数也发生了类似变化，进而与第二引线电容相连接的第三引线233输出给第三引线信号输出通道215的RXL信号发生改变，相应地，与第一引线电容相连接的第二引线信号输出通道213的RX3信号也发生改变。
需要说明的是，终端的处理器会实时对信号输出通道211、212、213、214、215和216输出的信号进行扫描以获取各条第二引线232和第三引线233输出信号的变化情况，对该第二引线232和第三引线233的扫描在时间上是独立的，可以先对第二引线232输出的信号进行扫描，也可以先对第三引线233输出的信号进行扫描。优选的，本实施例中，先对所述第三引线233输出的信号进行扫描，再对第二引线232输出的信号进行扫描，在该案例中，扫描之后即可得出第三引线信号输出通道215和第二引线信号输出通道213的信号发生了改变。
步骤3、请参见图2，由于终端预先记录了每个时刻由哪个信号输入通道输入信号，假设感测到触碰时脉冲信号是从信号输入通道221输入，后又经终端的处理器经扫描到第三引线信号输出通道215和第二引线信号输出通道213的信号发生了改变。具体地，由第三引线信号输出通道215可以首先确定触碰点在触摸屏的左边，再由第二引线信号输出通道213可以确定触碰点在左边部分中水平方向上的位置，进而由信号输入通道221可以进一步确定该触碰点在垂直方向上的位置，通过上述感测到的数据即可确定触碰了左点241。
需要说明的是，步骤3中出现了“水平方向”和“垂直方向”的描述，该描述是以图2作为参考展开的，在实际应用中，参考的对象不一样，描述的方式也不一样，但只要具有相同的原理就应落入本发明的保护范围。
进一步地，所述第一引线231的数量可以为多条，每相邻的两条所述第一引线231可以设置为相互平行，所述信号输入通道的数量可以为多条，每相邻的两条所述信号输入通道可以相互平行，所述第一引线231与所述信号输入通道一一对应连接。
进一步地，所述第一引线231与所述第二引线232可以互相垂直。
进一步地，所述第三引线233可以平行于所述第二引线232，所述感测电 路包括两个部分，每个部分布设N/2条第三引线233，每个部分的N/2条第三引线连接同一条所述第三引线信号输出通道。
进一步地，所述第一引线231、所述第二引线232或所述第三引线233为由规则图形的电性材料串接形成的引线。需要说明的是，对于第一引线231、第二引线232以及第三引线233的形状，此处不作限制，权利要求书中提到了平行、垂直等关系，这并不代表第一引线231、第二引线232或者第三引线233一定呈线性，第一引线231、第二引线232或者第三引线233可能是由规则图形拼接而成，如果其各自延伸的方向为同一个方向，那么也可以认为拼接形成的引线具备线性特征(如平行、垂直等关系)，以方便后续描述。
以图7为例，231、232和233分别对应第一引线、第二引线和第三引线，每一条引线都是由多个长方体状结构串接而成，每一条引线各自串接延伸的方向在同一条直线上，显然，构成第一引线、第二引线和第三引线的单位不限于方块状，还可以是三角形、菱形等其他形状，其形成引线的方式可参照方格的形成方式，此处不再赘述。另外，由于第一引线231与第二引线232交叉且绝缘，因此在第一引线231和第二引线232之间会形成桥接电路234。同理，由于所述第一引线231与所述第三引线233也交叉且绝缘，因此在该第一引线231和第三引线233之间会形成桥接电路235。
通过实施本发明实施例，将信号输出通道设置为至少两个类，一类用于检测发生变化的信号来自触摸屏的左边部分还是右边部分(还可以分为更多部分)，另一类用于判断发生变化的信号来自左边部分或右边部分的具体位置，以这种方式几乎可以将信号输出通道的数量减半，大大节省了材料成本。
在本说明书的描述中，参考术语“一个实施例”、“一些实施例”、“示例”、“具体示例”或“一些示例”等的描述意指结合该实施例或示例描述的具体特征、结构、材料或者特点包含于本发明的至少一个实施例或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施例或示例。而且，描述的具体特征、结构、材料或特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
以上所揭露的仅为本发明一种较佳实施例而已，当然不能以此来限定本发明之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流 程，并依本发明权利要求所作的等同变化，仍属于发明所涵盖的范围。
