"确认" 和 /或 "取消 " 等字符、 图标等。 本发明实施例中可根据需要显示的 字符数量设定触摸显示屏 1的数量， 例如在常用的 ATM机上的密码输入装 置可设置 12个功能键， 并且分别用于显示 "0-9" 这 10个数字以及 "确认" 和 "取消" 。
进一步的， 例如， 本发明一些实施例中各触摸显示屏 1之间彼此相互分 立， 即各触摸显示屏在结构上和功能上是相互独立的； 此时， 例如一个触摸 显示屏相当于原有密码输入装置中的一个机械按键，并被控制器 2独立控制。
进一步的， 例如， 本发明一些实施例中触摸显示屏 1的排布方式也可灵 活设置， 本发明一些实施例中各触摸显示屏之间具有设定的间距， 并以设定 方式排布。例如密码输入装置设置 12个触摸显示屏，并且分别用于显示" 0-9" 这 10个数字以及 "确认" 和 "取消" 时， 可釆用 4行 3列的方式排布， 如 图 2所示。 另外， 各个触摸显示屏 1之间可以具有设定的间隔。 当然该设定 的间隔可以尽量的小， 使得各触摸显示屏之间能够紧密接触， 外观上呈现为 无缝设置。 例如， 图 2所示的密码输入装置， 12个触摸显示屏为彼此分立的 触摸显示屏，这 12个触摸显示屏 1被控制器 2独立控制，并分别显示不同的 字符。
需要说明的是， 本发明一些实施例中构成触摸显示装置的功能键对应的 触摸显示屏 1 可以为具有显示功能和能够对触控操作进行感应的简单触摸 屏，例如在一般的显示屏上设置能够对触摸操作进行感应的感应器 101即可， 如图 3所示。 本发明一些实施例中感应器 101可以是能够感应到触控操作的 任何形式的感应器， 即本发明实施例中进行触控操作的感应通过一个感应器 即可简单实现， 无需复杂的触控扫描定位等操作。
较佳的， 例如， 本发明一些实施例中触摸显示屏 1可以是电容式触摸显 示屏、 电阻式触摸显示屏或电感式触摸显示屏， 本发明对此没有限制。 本发明的一个实施例中构成各触摸显示屏 1 例如为扭曲向列 （Twisted Nematic )型液晶显示屏。 扭曲向列型液晶显示屏具有窄视角的特点， 使得非 密码输入者很难窥视到功能键上显示的字符， 进一步提高安全性。
本发明一些实施例提供的密码输入装置包括至少两个彼此相互分立的触 摸显示屏， 由触摸显示屏替代现有密码输入装置中的机械按键， 并由控制器 控制触摸显示屏随机显示字符，故能够使作为密码的字符排布方式灵活多变， 提高密码输入的安全性。
本发明一些实施例中， 控制器 2控制触摸显示屏 1随机显示字符， 该显 示的字符可以包括但不限于 "0-9" 这 10个数字， 以及 "确认" 和 "取消" 等字符； 所有触摸显示屏上显示的字符最终的排布方式可以是乱序排布的， 也可是顺序排布的。 本发明实施例中， 优选乱序排布显示的字符， 以提高安 全性。
进一步的， 本发明一些实施例中控制器 2可在收到启动密码输入装置的 启动指令时， 控制各触摸显示屏 1随机显示字符， 在不使用 （例如处于待机 状态） 时， 则可不显示字符， 以节省资源。
更进一步的， 本发明一些实施例中控制器 2可在每次收到启动指令时， 控制各触摸显示屏显示的字符， 与上一次接收到启动指令时触摸显示屏上显 示的字符的排布方式不同。 例如， 每次更换密码输入者时， 需要重新启动密 码输入装置， 此时控制器 2控制触摸显示屏 1显示与上一次显示的字符不同 的字符， 以进一步提高安全性。
本发明一些实施例中， 处理器 3还可在检测到触控操作后， 向控制器 2 发送通知消息， 控制器 2可在接收到处理器 3发送的通知消息后， 更新触摸 显示屏上显示的字符， 以进一步提供安全性。
较佳的， 本发明一些实施例中控制器 2可在接收到处理器 3发送的通知 消息后， 将全部触摸显示屏上显示的字符都进行更新， 或者可以只更新部分 触摸显示屏上显示的字符。 控制方式可以是灵活的， 本发明不限于此。
优选的， 本发明一些实施例中， 控制器 2还可在密码输入者完成设定个 数的字符输入后， 更新各触摸显示屏上显示的字符， 例如可在用户完成输入 一个作为密码的字符后， 控制器就控制各触摸显示屏上显示与最近一次显示 的作为密码的字符不同的字符， 以更新各触摸显示屏上显示的字符。 本发明 一些实施例中该设定个数的字符可以根据密码输入者即将要输入的密码个数 进行设定， 例如密码输入者需要输入的密码个数为 6个， 则可设定完成 3个 或 4个作为密码的字符输入后，甚至可以是完成 6个座位密码的字符输入后， 更新各触摸显示屏上显示的作为密码的字符的排布方式，以更方便用户操作。
较佳的， 本发明一些实施例中， 处理器 3还可用于检测到触控操作， 并 确定受到触控操作的对应触摸显示屏上当前显示的字符为完成密码输入的确 认字符时， 向控制器 2发送完成密码输入的确认指令； 控制器 2可在接收到 处理器 3发送的完成密码输入的确认指令时，更新触摸显示屏上显示的字符， 以使密码输入装置在每次完成一次密码输入时， 能够及时更新字符， 避免非 密码输入者在记住了密码输入者输入密码的手型， 而在密码输入者离开后看 到密码的排布方式， 得知密码输入者输入的密码。
当然， 本发明一些实施例中， 控制器 2可在接收到处理器 3发送的通知 消息后， 将全部触摸显示屏上显示的字符都进行更新， 也可只更新部分触摸 显示屏上显示的字符， 控制方式灵活。
进一步的， 本发明的另一些实施例中， 控制器 2还用于： 以设定的周期 时长， 周期性更新各触摸显示屏上显示的字符， 以进一步提高安全性。
基于上述实施例提供的密码输入装置， 本发明的至少一个实施例提供一 种密码输入过程的实现流程， 如图 4所示， 包括：
S101: 启动密码输入装置。
本发明一些实施例中， 为了启动密码输入装置， 可在密码输入装置上的 功能键上设置相应的启动功能键， 通过该启动功能键输入启动指令， 以启动 密码输入装置。 当然还可根据密码输入装置连接的其它设备启动该密码输入 装置，例如在银行系统中使用的 ATM机上，可通过 ATM机识别到用户插入 银行卡时， 启动密码输入装置。
S102: 控制器控制各触摸显示屏上进行随机显示字符。
本发明一些实施例中控制器可通过例如软件程序方式实现控制各字符分 别在触摸显示屏上进行随机显示。 本发明实施例中每一触摸显示屏上显示的 字符为一个字符， 该字符例如可以是 "0-9" 这十个数字之一， 也可以是 "确 认" 字符以及 "取消" 字符。
本发明一些实施例中控制器控制各字符在各触摸显示屏上后， 整体的排 布方式以乱序形式进行显示， 以提高安全性， 防止非密码输入者通过分析密 码输入者输入密码的手型获取到密码输入者输入的字符。
S103: 处理器检测到触摸显示屏受到触控操作后， 确定受到触控操作的 对应触摸显示屏上当前显示的字符， 并按照触控操作的先后顺序， 确定出用 户输入的字符串， 将该字符串作为用户输入的密码。
例如， 本发明一些实施例中每个功能键对应的触摸显示屏中设置有能够 对触控操作进行感应的感应器。 因此， 当触摸显示屏受到触控操作时， 感应 器能够感应到该触控操作， 并由处理器检测具体是哪个感应器感应到触控操 作， 进而检测到受到触控操作的触摸显示屏， 并将受到触控操作的触摸显示 屏上当前显示的字符作为需要输入的字符， 进行输入。
优选的， 本发明一些实施例中控制器可在每次接收到启动密码输入装置 的启动指令时， 更新各触摸显示屏上显示的字符。 例如在 ATM机上， 当每 次有用户插入银行卡时， 控制器就控制各触摸显示屏上显示与最近一次显示 的字符不同的字符， 以更新各触摸显示屏上显示的字符的排布方式。
优选的， 本发明一些实施例中控制器还可在密码输入者完成设定个数的 密码字符输入后， 更新各触摸显示屏上显示的字符。 例如， 可在用户完成输 入一个密码字符后， 控制器就控制触摸显示屏上显示与最近一次显示的密码 字符不同的字符， 以更新各触摸显示屏上显示的字符。 本发明一些实施例中 该设定个数的字符可以根据密码输入者即将要输入的密码个数进行设定， 例 如密码输入者需要输入的密码个数为 6个， 则可设定完成 3个、 4个或 6个 密码字符输入后， 更新各触摸显示屏上显示的字符， 以更方便用户操作。
优选的， 本发明一些实施例中还可以设定的周期时长， 周期性的更新各 触摸显示屏上显示的字符的排布方式， 使密码输入装置使用达到一定的时间 后，使各触摸显示屏上显示的字符的排布方式得到变化，进一步提高安全性。
本发明一些实施例中控制器根据不同的情况， 能够控制各触摸显示屏上 随机显示的字符进行更新， 故能够使作为密码的字符整体的排布方式灵活多 变， 进一步提高密码输入的安全性。 发明的精神和范围。 这样， 倘若本发明的这些修改和变型属于本发明权利要 求及其等同技术的范围之内， 则本发明也意图包含这些改动和变型在内。 本申请要求于 2014年 1月 22日递交的中国专利申请第 201410030868.6 号的优先权， 在此全文引用上述中国专利申请公开的内容以作为本申请的一 部分。
