图 2 为根据本发明实施例提供的电磁式电子书阅读器选通扫描天线阵列的方法 流程；
图 3为根据本发明实施例提供的电磁感应天线板天线阵列的划分示意图； 图 4为根据本发明实施例提供的电磁式电子书阅读器的工作流程图。 具体实施方式
以下结合附图和实施例进一步清楚、 完整的说明本发明的技术方案。
本发明提供的电子书阅读器基于电子书阅读器的阅读模式按区域划分电磁感应 天线板内的天线阵列， 这样， 电子书阅读器的各个功能阅读模式的用户界面映射某个 或某几个天线阵列区域， 在相应的功能阅读模式下， 仅扫描该用户界面映射的天线阵 列区域， 极大地降低了带电磁感应功能的电子书阅读器的功耗。
如图 1所示， 本发明提供的电子书阅读器， 包含电子纸显示屏 1和与电子纸显示屏 电连接的主控制模块 2。 电子纸显示屏 1的一面为显示信息的显示面， 紧贴电子纸显示 屏另一面设置有电磁感应组件 4， 该电磁感应组件 4包括电磁感应触摸屏 401和电磁感 应控制模块 402， 电磁感应触摸屏 401是由感应线圈纵横交错并行排列形成的一层电磁 感应天线板。 电磁感应触摸屏 401与电磁感应控制模块 402电连接， 用于感应电磁笔 3 输入的轨迹信息并以波形的形式将电磁笔轨迹信息和压感信息传送给电磁感应控制 模块 402。 电磁感应控制模块 402与主控制模块 2电连接， 用于将获得的电磁笔轨迹信 息和压感信息进行模数转换得到数字信号， 并将该数字信号传送给主控制模块 2。
主控制模块 2包含主处理器 202、 显示驱动模块 201和存储器 203。 主处理器 202给 电磁感应控制模块 402发送开通或关闭某个或某些扫描区域的命令， 电磁感应控制模 块 402控制电磁感应天线板 401执行相应的命令扫描感应线圈发送电磁波， 并将获得的 电磁笔信息发送给主处理器。 主处理器 202将获得的电磁笔信息发送给显示驱动模块 201 , 由显示驱动模块 201驱动电子纸显示屏 1显示电磁笔信息。 存储器 203用于存储用 户界面信息、 电磁笔书写的轨迹信息、 压感信息以及其他数据信息。
如图 2所示， 本发明实施例提供的电磁式电子书阅读器选通扫描天线阵列的方法 包括如下步骤：
S101 , 根据电磁式电子书阅读器的用户界面将电磁感应天线板的天线阵列进行划 分， 形成多个独立的天线阵列区域； S 102 , 建立电磁式电子书阅读器用户界面与各个独立的天线阵列区域的映射关 系；
S 103， 根据电磁式电子书阅读器用户界面与各个独立的天线阵列区域的映射关 系确定需要扫描的天线阵列区域。
上述 S 101中， 电磁式电子书阅读器的用户界面根据用户的操作需求设计有相应 的功能区域。 电磁感应天线板的天线阵列根据用户界面上设置的功能区域进行划分， 本实施例中， 电磁感应天线板划分成 7个独立的天线阵列区域， 如图 3所示， 分别是 A1天线阵列区域、 A2天线阵列区域、 A3天线阵列区域、 A4天线阵列区域、 A天线 5 阵列区域、 A6天线阵列区域和 A7天线阵列区域。
S 102中， 建立电磁式电子书阅读器的用户界面与各个独立的天线阵列区域的映 射关系， 是由电磁式电子书阅读器在不同工作模式下呈现的各个用户界面与各个独立 的天线阵列区域中的至少一个独立的天线阵列区域进行映射的。 电磁式电子书阅读器 在不同的工作模式下， 会有不同的用户界面， 各个用户界面具有各自不同的功能操作 需求并据此在用户界面上形成功能区域。 如在电磁式电子书阅读器处于阅读模式时， 假设用户在阅读模式下只需要点击菜单键、 关闭当前页面键和选择页码键， 点击菜单 键、 关闭当前页面键和选择页码键在用户界面上所处的区域即为功能区域。 用户界面 与独立天线阵列区域映射关系的建立， 即是由这些功能区域分别映射各自的独立天线 阵列区域完成的。
本实施例中， 菜单键功能区域映射 A1天线阵列区域， 关闭当前页面键功能区域映 射 A3天线阵列区域， 选择页码键功能区域映射 A2天线阵列区域， 内容显示功能区域映 射 A4、 A5、 A6天线阵列区域， 翻页滚动条功能区域映射 A7天线阵列区域。
电磁式电子书阅读器的用户界面信息存储在主控制模块内置的存储器中， 用户界 面信息包括用户界面上的功能区域信息以及功能区域与天线阵列区域映射关系的信 息等。
S 103 中， 由主控制模块内置的主处理器根据存储器发送的信息控制天线阵列区 域的开通与关闭， 存储器发送的信息包括电磁式电子书阅读器所处的用户界面、 该用 户界面的功能区域与天线阵列区域的映射关系以及需要操作哪些功能区域等信息。 在 电磁式电子书阅读器打开某个用户界面时， 如阅读模式的用户界面， 假设阅读模式的 用户界面只需要操作菜单键、 选择页码键和关闭当前页面键， 主控制模块控制开通分 别与菜单键、 选择页码键和关闭当前页面键功能区域映射的 A1天线阵列区域、 A2天 线阵列区域和 A3 天线阵列区域并进行扫描， 由于不需要操作内容显示功能区域和翻 页滚动条功能区域， 主控制模块控制关闭与内容显示功能区域映射的 A4、 A5、 A6天 线阵列区域以及控制关闭与翻页滚动条功能区域映射的 A7 天线阵列区域。 这样， A1 天线阵列区域、 A2天线阵列区域和 A3天线阵列区域内的感应线圈在主控制模块的控 制下处于开通状态即不断发射电磁波的工作状态， 而 A4天线阵列区域、 A5天线阵列 区域、 A6天线阵列区域、 A7 天线阵列区域内的感应线圈在主控制模块的控制下处于 关闭状态即停止发射电磁波。
本实施例中， 电磁感应天线板天线阵列区域的划分和电磁式电子书阅读器功能区 域的划分是为了方便说明本实施例的技术方案而进行的简单划分。 具体实施过程中， 可根据实际需要任意划分天线阵列区域并建立其与电磁式电子书阅读器功能区域之 间的映射关系。
如图 4所示， 在电磁式电子书阅读器处于正常阅读状态、 手写批注状态和直接跳 页状态三种状态时， 电磁感应天线板 4001选通天线阵列区域进行扫描。 在此结合图 1 予以详细说明， 电磁式电子书阅读器处于正常阅读模式时， 存储器 203向主控制模块 2 内置的主处理器 202发送该模式下的用户界面信息， 主处理器根据所获得的用户界面 信息， 向电磁感应控制模块 402发出开通与关闭相应天线阵列区域的指令， 电磁感应 控制模块控制电磁感应天线板开通与关闭相应的天线阵列区域。 具体而言， 在电磁式 电子书阅读器处于正常阅读模式下， 主控制模块 2控制电磁感应天线板开通 A1天线阵 列区域扫描、 A3天线阵列区域扫描， 关闭 A2、 A4、 A5、 A6、 A7天线阵列区域。 试验数 据证明， 只开通 Al、 A3阵列区域扫描感应线圈一次所需要的时间大概为 20毫秒， 而扫 描一次整个电磁感应天线板所需要的时间大概为 150毫秒， 此时的功耗可以达到全屏 扫描的 1/7左右， 大大降低了电磁式电子书阅读器的功耗。
当电磁式电子书阅读器处于直接跳页状态时， 开通 A7天线阵列区域扫描， 关闭其 他天线阵列区域扫描。 在阅读模式需要进行批注时， 点击菜单键的图标， 在下拉菜单 中选择 "添加批注" 的选项， 点击该选项后， 电磁式电子书阅读器从阅读模式进入批 注模式。 在批注模式下， 根据显示内容选择打开 A4天线阵列区域、 A5天线阵列区域、 A6天线阵列区域进行扫描。
电磁式电子书阅读器处于不同工作模式下各个独立的天线阵列区域的开通或关 闭， 可以是由主控制模块控制完成， 也可以是通过设置在电磁式电子书阅读器上的按 钮手动选择需要开通或关闭的天线阵列区域， 或者通过调出电磁式电子书阅读器上的 虚拟按键进行选择。
