若所述触摸操作的响应信息的集合与所述预设的响应信息的集合一 致， 则执行 305。
303、 获得所述触摸操作的响应信息集合与预设的响应信息集合的交集 后， 得到所述交集和所述预设的响应信息集合的补集； 确定所述补集中包 括的触摸点位置对应的触摸点断路。
304、 若所述触摸操作的响应信息集合包括第一触摸点的位置， 则确定 所述第一触摸点的位置对应的触摸点短路； 所述第一触摸点位置为所述触 摸操作的响应信息集合中包括偶数个同一触摸点的位置。
305、 确定所述触摸屏的显示区域工作状态正常。 如图 2所示， 该触摸屏示例性的包括 9条 X轴和 9条 Y轴， 预设区域为沿 着该触摸屏的最左端从上之下移动到所述触摸屏的最低端， 然后从左至右 移动到屏幕的最右端。 在所述触摸屏工作状态正常时， 该触摸屏对该触摸 操作的响应信息中包括的触摸点个数为 18个， 则预设的响应信息集合中包 括的这 18个触摸点的位置信息。 假若， 第二行的 X轴的 A电极和 B电极断路，第三行的 X轴的电极无法连 通， 这样 C电极和 D电极之间无法产生电容变化，触摸屏感应不到电极 C和 D 组成的触摸点的电容变化， 则不会向电子设备上报中断信号， 电子设备也 无法接收到触摸屏上报的中断信号， 这样为了能够判断所述触摸屏从而所 述的显示区域工作状态不正常的位置和故障类型， 便于修复， 首先需要获 得触摸屏对预设区域的触摸操作的响应信息集合与预设的响应信息集合的 交集， 这样将该交集与所述预设响应信息集合的补集中包括的触摸点的位 置对应的触摸点确定为断路。 假若， 第四行 X轴的 E电极和第五行 X轴的 F电极之间短路， 由于第四行 的电极相连通， 第五行的电极也相连通， 这样在触摸操作移动到第四 X轴的 最左端的 M电极时， 不仅 M电极与第一列 Y轴的 L电极之间产生电容变化， 第五 X轴的最左端的 N电极与 L电极之间也会产生电容变化， 同样， 在触摸 操作移动到第五 X轴最左端的 N电极时，不仅 N电极与 L电极之间产生电容变 化， M电极也会与 L电极产生电容变化， 这样触摸屏则分别会向电子设备上 报两次 M电极和 L电极、 以及 N电极和 L电极组成的触摸点的位置。 从而对 该触摸操作响应包括的第一触摸点的位置， 所述第一触摸点位置为所述触 摸操作的响应信息集合中包括偶数个同一触摸点的位置。 若电子设备确定该触摸屏的显示区域断路或短路， 可以通过报警的方 式， 或者在触摸屏上显示异常的图案等方式， 本实施例对此不作具体限定。 当然， 若只是为了检测所述触摸屏的显示区域工作状态是否正常， 所 述电子设备获得的所述触摸屏对预设区域的触摸操作的响应消息只需要包 括响应的触摸点个数和触摸点位置的至少一个， 这样所述电子设备只需要 确定所述触摸操作的响应信息集合是否与预设的响应信息一致。 若所述触 摸操作的响应信息集合与预设的响应信息集合一致， 则所述触摸屏工作状 态正常， 若所述触摸操作的响应信息集合与预设的响应信息集合不一致， 即两个集合包括的触摸点的个数不同和 /或触摸点的位置不同， 则所述触摸 屏工作状态不正常。 若电子设备确定该触摸屏的显示区域断路或短路， 可以通过报警的方 式， 或者在触摸屏上显示异常的图案等方式， 本实施例对此不作具体限定。 需要说明的是， 在本实施例中， 示例性的预设区域为沿着该触摸屏的 最左端从上之下移动到所述触摸屏的最低端， 然后从左至右移动到屏幕的 最右端， 但是预设区域也可以其它的区域。 只要该预设区域可以覆盖每一 行的至少一个电极和每一列的至少一个电极即可， 对此本实施例不作具体 限定。
另外对于， 本发明实施例中的 303和 304没有必然的前后关系， 只要是 获得触摸操作的响应信息后确定触摸操作响应信息与预设的响应信息不一 致， 则可以先确定触摸屏是否短路， 也可以先判断触摸屏是否断路， 本发 明实施例对此不作具体限定。 本发明实施例提供的一种检测电容式触摸屏的方法， 根据获得的所述 触摸屏对所述预设区域的触摸操作的响应信息集合和预设的响应信息集合 包括的触摸点个数和 /或触摸点的坐标位置， 可以自动确定所述触摸屏工作 状态是否正常， 且可以根据触摸点的坐标位置确定该触摸屏故障类型， 例 如断路或短路的位置， 不需要根据人工来判断， 从而可以提高触摸屏的检 测效率。
实施例三、 如图 4所示， 为了能够检测非显示区域的触摸按键工作状态是否正常， 本发明实施例还提供了一种检测电容式触摸屏的方法， 本实施中将非显示 区域为电子设备上能够用于触摸的按键， 该触摸按键的位置位于显示区域 以外， 则所述预设区域位于非显示区域， 具体为非显示区域的触摸按键， 所述预设的响应信息集合包括预设的显示区域的触摸点位置， 该方法包括：
401、 根据所述触摸屏对所述触摸操作的响应， 获得所述触摸操作的响 应信息集合， 所述触摸操作的响应信息的集合包括对所述触摸操作响应的 显示区域的触摸点位置。
402、 若所述触摸操作的响应信息的集合包括的触摸点位置与所述预设 的响应信息集合包括的触摸点位置不一致， 则确定所述触摸屏的非显示区 域工作不正常。 如图 5所示， 所述非显示区域 51的触摸按键 511的预设响应信息集合为 显示区域 52的触摸点 G的坐标位置， 非显示区域 51的触摸按键 512的预设响 应信息集合为显示区域 52的触摸点 H的坐标位置，非显示区域 51的触摸按键 513的预设响应信息集合为显示区域 52的触摸点 J的坐标位置，若所述触摸按 键 511、 512、 513工作状态正常时， 则在触摸这三个按键时， 显示区域 52的 触摸点 G、 H、 J会进行响应。 若触摸按键 511断路， 这样电子设备获得的触 摸操作响应信息中不包括触摸点 G的坐标位置， 相应的， 若11、 J断路， 会出 现同样的问题。 若触摸按键 511和触摸按键 512短路， 电子设备获得的触摸 操作相应信息中包括触摸点 G和 H的坐标位置， 由此也可以判断触摸按键 511和触摸按键 512短路。 本实施例利用触摸屏的显示区域来检测电子设备的触摸按键， 若对某 一触摸按键进行触摸操作， 若触摸屏的显示区域进行响应的触摸点和预设 的触摸点的坐标位置一致， 则确定该触摸按键工作正常； 若触摸屏的显示 区域进行响应的触摸点和预设的触摸点的坐标位置不一致， 则确定该触摸 按键工作状态不正常。 本发明实施例提供的一种检测触摸屏的方法， 根据获得的所述触摸屏 对所述预设区域的触摸操作的响应信息集合和预设的响应信息集合中包括 的触摸点的坐标位置， 可以自动确定所述触摸屏的触摸按键工作状态是否 正常， 不需要根据人工来判断， 从而可以提高触摸屏的检测效率。
实施例四、 如图 6所示， 本发明实施例还提供了一种检测电容式触摸屏的装置， 其 中该装置上集成有触摸屏， 该装置包括： 触摸屏 61和处理器 62。 所述触摸屏 61 , 用于对预设区域的触摸操作进行响应， 并将响应的信 息发送给所述处理器。 所述处理器 62, 用于接收所述触摸屏发送的响应信息， 获得所述触摸 操作的响应信息的集合； 若所述触摸操作的响应信息的集合与预设的响应 信息集合不一致， 确定所述触摸屏工作状态不正常。 触摸屏 61在接收到触摸操作后， 若所述触摸操作触摸的触摸区域的触 摸点没有短路和断路， 则该触摸区域的触摸点的电容值会发生变化， 触摸 点向处理器 62上报一个中断信号和上报该触摸点的坐标位置中的至少一 个。 由于每次触摸操作依次可能会触摸到了该触摸屏的多个触摸点， 这样 该处理器 62根据所述触摸屏对所述触摸操作的响应， 获得所述触摸操作的 响应信息集合。 为了能够检测该触摸屏的工作状态是否正常， 该装置 60中存储有预设 的响应信息集合。 这样若处理器 62获得的所述触摸操作的响应信息集合与 预设的响应信息的集合不一致， 则处理器 62确定所述触摸屏工作状态不正 常。 若处理器 62获得的所述触摸操作的响应信息集合与预设的响应信息集 合一致， 则该处理器 62确定所述触摸屏工作状态正常。 具体的， 在检测触摸屏的显示区域工作状态是否正常时， 所述预设区 域在所述触摸屏的显示区域。 所述触摸操作的响应信息集合包括所述触摸屏对所述预设区域的触摸 操作响应的触摸点个数和触摸点的位置的至少一个。 所述预设的响应信息集合包括所述触摸屏工作状态正常时， 所述触摸 屏对所述预设区域的触摸操作响应的触摸点个数和触摸点位置的至少一 个。
若仅是为了检测所述触摸屏的显示区域的工作状态是否正常， 所述处 理器 62确定所述触摸屏工作状态不正常具体包括：
若所述触摸操作的响应信息的集合包括的触摸点个数和 /或触摸点位置 与所述预设的响应信息的集合包括的预设的触摸点个数和 /或触摸点位置不 一致， 确定所述触摸屏 61工作状态不正常。 若为了检测所述触摸屏 61的显示区域工作状态不正常的位置和故障类 型， 所述处理器 62确定所述触摸屏 61的显示区域的工作状态不正常具体包 括：
获得所述触摸操作的响应信息集合与预设的响应信息集合的交集后， 得到所述交集和所述预设的响应信息集合的补集； 则确定所述补集中包括 的触摸点位置对应的触摸点断路；
若所述触摸操作的响应信息集合包括第一触摸点的位置， 则确定所述 第一触摸点的位置对应的触摸点短路； 所述第一触摸点位置为所述触摸操 作的响应信息集合中包括偶数个同一触摸点的位置。 在检测触摸屏 61的非显示区域的触摸按键工作状态是否正常时， 所述 预设区域为所述触摸屏的非显示区域， 具体可以是任意触摸按键。 其中， 所述触摸操作的响应信息的集合包括对所述触摸操作响应的显 示区域的触摸点位置。 所述预设的响应信息集合包括预设的显示区域的触摸点位置。 所述处理器 62确定所述触摸屏 61的非显示区域的工作状态不正常具体 包括：
若所述触摸操作的响应信息的集合包括的触摸点位置与所述预设的响 应信息集合包括的触摸点位置不一致， 则确定所述触摸屏的非显示区域工 作不正常。 本发明实施例提供的一种检测电容式触摸屏的装置， 根据处理器获得 的所述触摸屏对所述触摸操作的响应信息集合和预设的响应信息集合中包 括的触摸点的个数和 /或坐标位置， 处理器可以自动确定所述触摸屏的触摸 按键工作状态是否正常， 不需要根据人工来判断， 从而可以提高触摸屏的 检测效率。 需要说明的是， 以上发明实施例提供的一种检测电容式触摸屏的装置， 具体可以是集成该触摸屏的电子设备， 例如手机、 电脑等。 本发明实施例还提供了一种移动终端， 包括上述实施例提供检测电容 式触摸屏的装置， 具体结构在此不再赘述。 本领域普通技术人员可以理解： 实现上述方法实施例的全部或部分步 骤可以通过程序指令相关的硬件来完成， 前述的程序可以存储于一计算机 可读取存储介质中， 该程序在执行时， 执行包括上述方法实施例的步骤； 而前述的存储介质包括： ROM、 RAM, 磁碟或者光盘等各种可以存储程序 代码的介质。 以上所述， 仅为本发明的具体实施方式， 但本发明的保护范围并不局 限于此， 任何熟悉本技术领域的技术人员在本发明揭露的技术范围内， 可 轻易想到变化或替换， 都应涵盖在本发明的保护范围之内。 因此， 本发明 的保护范围应以所述权利要求的保护范围为准。
