说明书
近场通信系统和终端
技术领域
本发明涉及通信技术领域, 尤其涉及一种近场通信系统和终端。 背景技术
近场通信是一种短距离的高频无线通信方式, 终端之间可以通过近场通信 在大约十厘米的范围内进行非接触式点对点的数据传输。 在传统的具有近场通 信功能的电容式触摸屏终端中, 近场通信模块与触控检测模块分布在不同的集 成芯片上。 近场通信模块使用专用天线实现与其它终端的数据传输, 而触控检 测模块则通过触摸传感器上的驱动电极和感应电极来检测触终端的触摸屏上是 否有触发操作及触发操作的位置。 由于采用了两个集成芯片, 因而使得硬件电 路结构复杂且体积较大。
目前, 可以采用检测电场的方式在触控芯片上实现近场通信功能。 具体而 言, 具有第一电容式触摸屏的第一终端将待发送数据转换成二进制数据后, 对 第一电容式触摸屏上参与数据传输的电极施加电压, 形成相应的电场分布。 当 具有第二电容式触摸屏的第二终端接触第一终端时, 第二终端会检测出该电场 分布, 从而解析出相应的第一终端发送的数据。
目前存在的问题是, 由于是采用电场检测方式, 若第一电容式触摸屏和第 二电容式触摸屏之间尺寸差别较大, 则会引起通信质量下降, 造成数据无法传 输。 此外, 由于具有较大尺寸的电容式触摸屏的终端与具有较小尺寸的电容式 触摸屏的终端之间的不匹配,导致通信信号衰减较大,并且容易受到外界干扰, 同时也增加了检测的复杂度。

下面参考附图描述根据本发明实施例的跨终端通信的系统和终端。
目前, 终端之间在近场通信时, 第二终端的第一电容式触摸屏和第一终端 的第二电容式触摸屏之间尺寸往往相差很大, 因此会引起通信质量下降, 造成 数据无法传输。 例如, 如图 1所示, 笔记本电脑与手机进行近场通信时, 笔记 本电脑在打开屏幕的状态, 等待手机的靠近; 手机接近笔记本电脑的屏幕任意 位置均可实现数据传输。 虽然上述方式对用户的操作要求较低, 但是在应用上 存在一个较大的问题。 由于笔记本电脑中用于接收有效数据传输信号的面积较 小(接收有效数据信号的面积为不超过手机面积大小), 因此导致笔记本电脑的 其它接收区域不仅无法有效的接收数据传输信号, 而且会接收到噪声。 此外, 笔记本电脑中的接收区域的非有效部分 (如没有与手机发射区域对应的区域部 分) 还可能与手机中系统地 GND耦合, 因此, 会导致有效信号被抵消掉, 当手 机靠近笔记本电脑发射数据传输信号时, 笔记本电脑接收的信号较弱, 通信质 量较低, 难以实现稳定的传输。 因此, 如果可以通过减少笔记本电脑的接收面 积来增强数据传输的信号, 也就是说手机与笔记本电脑在笔记本电脑中指定的 通信区域进行通信, 由此可以减少信号衰减和外界干扰, 提高了通信质量。 为 此本发明提出了一种跨终端通信的系统。
图 2是根据本发明一个实施例的近场通信系统的结构示意图。如图 2所示, 该近场通信系统包括第一终端 100和第二终端 200, 其中, 第一终端 100包 括: 第一近场通信区域 110, 第二终端 200包括: 第二近场通信区域 210、 第一子单元 211和第二子单元 212。
具体地,第一终端 100具有第一近场通信区域 110,其中,第一终端 100 可为手机等。第二终端 200具有第二近场通信区域 210,其中,第二终端 200 可为笔记本电脑、 掌上电脑、 电视、 显示器等。 第二近场通信区域 210具有 第一子单元 211和第二子单元 212, 第一子单元 211和第二子单元 212, 或 者仅仅是第二子单元 212用于检测第一近场通信区域 110与第二近场通信区 域 210之间的距离是否小于等于预设距离,第二子单元 212用于在第一近场 通信区域 110与第二近场通信区域 210之间的距离小于等于预设距离时,与 第一近场通信区域 110建立通信, 其中, 第一近场通信区域 110和第二近场 通信区域 210的第二子单元 212可通过近场通信的方式进行通信。上述检测 第一近场通信区域 110与第二近场通信区域 210之间的距离是否小于等于预 设距离均可通过现有技术实现, 为了避免冗余, 此处不再详细介绍。
举例说明, 第一终端 100 (比如手机) 具有较小面积的近场通信区域, 第二终端 200 (比如笔记本电脑、平板电脑)具有较大面积的近场通信区域。 例如, 第一终端 100为手机, 第二终端 200为平板电脑; 或者第一终端 100 为掌上电脑, 第二终端 200为笔记本电脑等。 第一终端 100和第二终端 200 分别具有第一近场通信区域 110和第二近场通信区域 210。 例如, 第一近场 通信区域 110为手机的显示屏,第二近场通信区域 210为笔记本电脑的显示 屏, 或者第一近场通信区域 110 为手机的显示屏, 第二近场通信区域 210 为触摸板等。
可将第一终端 100和第二终端 200之间的通信过程拆分为接近检测和数 据通信; 接近检测是数据通信的准备阶段。 一般地, 触摸检测和接近检测分 时进行, 接近检测成功后才进入数据通信阶段。可以将触摸检测和接近检测 称之为第一检测阶段, 将数据近场通信称之为第二检测阶段。在第一检测阶 段中, 触摸设备可同时支持触摸功能和接近检测功能。 以下主要论述第一检 测阶段中的触摸检测, 接近检测的处理方式与触摸检测类似。
接近检测的目的是使第二终端 200感知是否存在与第二终端 200通信的 第一终端 100, 由于此时第二终端 200无需和第一终端 100进行数据传输, 因此对通信质量的要求较低。
具体地, 利用检测通道切换的方式, 可实现第二终端 200的第二近场通 信区域 210中不同区域的触摸检测和接近检测。 如图 3, 是根据本发明一个实施例的近场通信系统进行固定通道切换的 处理流程图, 具体流程为:
S102,首先对第一子单元 211和第二子单元 212组成的整屏进行触摸检测, 完成第一阶段检测的触摸检测;
S104, 对第一子单元 211和第二子单元 212组成的整屏进行接近检测, 完 成第一阶段检测的接近检测;
S106, 在接近检测阶段, 通过检测结果判断是否存在第一终端 100与第 二终端 200小于等于预设距离, 是则转向 S108, 否则转向 S110;
S108,通过第二子单元 212接近检测结果判断第一终端 100是否位于其 中, 是则转向 S114, 否则转向 S112;
S112,提示用户将第一终端 100移动到第二终端 200的第二子单元 212, 转向 S102; S114, 存在第一终端 100, 则通过第二子单元进行数据传输, 完 成通信;
S110,不存在第一终端 100,转向 S102 ,重新进行触摸检测和接近检测。 如图 3-1所示,第二终端 200的第二近场通信区域 210中可具有第一子 单元 211和第二子单元 212。 具体而言, 可采用软件分割的方式将第二近场 通信区域 210划分为大小不同的两个区域, 即第一子单元 211 (虚线框以外 区域) 和第二子单元 212 (虚线框内区域) 。 在检测到第一终端 100的第一 近场通信区域 110接近第二终端 200的第二近场通信区域 210时,通过第二 子单元 212和第一终端 100的第一近场通信区域 110建立通信。其中, 当第 二子单元 212与第一近场通信区域 110进行通信时,控制第二近场通信区域 210中的第一子单元 211 (其中的全部或部分通道) 停止工作。
具体的, 停止工作主要指通道保持对其他通道干扰较小的状态, 如断开 (悬浮) 状态或直流固定电平状态, 尤其指保持直流固定电平状态。
如图 3-1所示, ΥΓΥ7为纵向通道, ΧΓΧ9为横向通道, 这些电极用于作 为触摸和近场通信电极通道 (典型互容触摸屏 ΥΓΥ。为驱动通道, 1。〜 12为 感应通道; 应当理解的是, 也可以一个检测通道同时兼有驱动功能和感应功 能, 检测通道主要指带有感应功能的电极通道) 。 对于 ΥΓΥ7为驱动通道, Χ。〜Χ9为感应通道的第二近场通信区域 210来说,在对第二近场通信区域 210 进行第一阶段检测的触摸扫描时,应当对第二近场通信区域 210中的所有电 极通道均进行扫描。也就是说, 不仅对第一子单元 211中的所有驱动通道和 感应通道, 而且对第二子单元 212中的所有驱动通道和感应通道进行扫描。 此时将得到的数据用于对第二近场通信区域 210的触摸处理。应当理解的是 如果需要通过整屏进行接近检测,则可以依照上述触摸检测类似的处理方式 完成第一阶段的接近检测; 如果仅需要对第二子单元进行接近检测, 则仅对 指定第二子单元 212的所有驱动通道和部分感应通道(如图 3中虚线区域中 的通道 ΧΓ ) 进行扫描, 完成接近检测处理。
在对第二近场通信区域 210进行第二阶段检测的数据近场通信时,仅对 指定第二子单元 212的所有检测通道 (如图 3中虚线区域中的通道 ΧΓ ) 进行扫描,此时得到的数据用于对第二近场通信区域 210的通信处理。由此, 仅通过指定区域 (即第二子单元 212 ) 和第一终端 100进行近场通信的话, 第二终端 200用于接收有效信号的面积保持不变,而用于整体接收的面积减 小, 因此, 提高了信号的通信质量。
应当理解的是, 如果第二终端 200中 ΧΓΧ9同时兼有驱动和感应功能, 在数据传输时还可以仅使用第二子单元 212的 ΧΓΧ9通道来进行驱动和接收, 由此可以节省第二终端 200的电量。
第二终端 200既可支持固定的软件分割区域,将第二终端上指定区域的 检测通道 (如图 3 中的 ΧΓΧ9 ) 设为第二子单元, 剩下的检测通道设为第一 子单元,也可以动态的将第二终端上与第一近场通信区域重叠的检测通道设 为第二子单元, 剩下的检测通道设为第一子单元。
如图 3-2 所示为根据本发明一个实施例的第二终端显示屏自动检测分割 位置并进行通道切换的处理方法流程图, 该方法包括:
S202 ,首先对第一子单元 211和第二子单元 212组成的整屏进行触摸检测, 完成第一阶段检测的触摸检测;
S204,对第二近场通信区域 210上的所有通道分别进行接近检测扫描,完 成第一阶段检测的接近检测;
S206 , 在接近检测阶段, 通过检测结果判断第二子单元内是否存在第一 终端 100与第二终端 200小于等于预设距离,是则转向 S208 ,否则转向 S210 ;
S208 , 根据每个通道的扫描情况, 可以判断第一终端 100的接触位置;
S212 , 根据第一终端接近位置, 将两者重叠范围内的检测通道划分为第 二子单元 212, 用于进行后续的近场通信, 范围外的其他通道划分为第一子 单元 211 ;
S214, 根据 S212划分的区域, 第二终端 200通过第二子单元 212与第 一终端完成通信。 如图 3-3 (图中省略了 Y通道) , 在对第二近场通信区域 210进行第一 阶段的接近检测时,可以通过不同通道的差异情况了解第二终端 100的位置: 首先对整屏上所有通道进行接近检测扫描; 通过不同通道的数据差异, 可以 发现第一终端 100放置在 ΧΓΧ4附近。 如图 3-4, 了解到第二终端 100的放 置位置后, 第二终端 200 自动将第二通信区域 210的 Χ3、 Χ4划分为第二子单 元 212进行后续的近场通信, 此时其他的通道组成了第一子单元 211。 在通 信阶段时, 仅对图中指定第二子单元 212的部分通道进行扫描接收, 从而提 高了通信质量。
本发明实施例的近场通信系统, 通过采用软件分割的方式, 利用通道切 换将第二终端的近场通信区域中的指定区域作为专用的通信区域,在第二终 端检测到第一终端接近时, 通过该指定区域和第一终端进行近场通信, 减少 数据传输中信号衰减和外界干扰, 提高了通信质量。
虽然在上述实施例中通过通道切换可以较好的解决第一终端 100和第二终 端 200之间数据传输时信号较弱的问题, 但是在第二终端 200具有更加大近场 通信区域 (例如 20英寸或者大于 20英寸) 的情况下, 由于第二终端 200的第 二近场通信区域 210中驱动通道或感应通道之间的间距过长,导致第一终端 100 与第二终端 200在数据传输时仍然存在信号较弱的问题。 因此, 在下述实施例 中, 还可将第二终端 200中的第二近场通信区域 210通过硬件分割的方式分为 两块, 通过两块具有独立驱动通道和感应通道的电极区组成一个大的第二近场 通信区域 210。 由此, 可以更好地解决第一终端 100与第二终端 200在数据传 输时信号较弱的问题。
图 4是根据本发明另一个实施例的近场通信系统的结构示意图。如图 4所 示,该近场通信系统包括第一终端 100和第二终端 200,其中,第一终端 100 包括:第一近场通信区域 110,第二终端 200包括:第二近场通信区域 210、 第一子单元 211、 第二子单元 212。
具体地,第二近场通信区域 210包括第一子单元 211和第二子单元 212, 第一子单元 211和第二子单元 212, 或者仅仅是第二子单元 212用于检测第 一近场通信区域 110与第二近场通信区域 210之间的距离是否小于等于预设 距离,第二子单元 212用于在检测到第一近场通信区域 110与第二近场通信 区域 210之间的距离小于等于预设距离时,与第一近场通信区域 110建立通 信。
进一歩而言,第二终端 200在没有检测到第一近场通信区域 110与第二 近场通信区域 210之间的距离小于等于预设距离的时候,需要分时对第二终 端 200的第二近场通信区域 210进行触摸检测和接近检测,接近检测成功后 才进入数据通信阶段。 可以将触摸检测 +接近检测称之为第一阶段检测, 将 数据近场通信称之为第二阶段检测。
图 5是根据本发明一个实施例的将第二终端的显示屏分为两块的处理方法 流程图, 具体流程为:
S302 , 分别扫描第一子单元 211和第二子单元 212, 对数据进行拼接等处 理, 得到整屏数据后, 完成触摸检测;
S304, 分别扫描第一子单元 211和第二子单元 212, 对数据进行拼接等处 理, 得到整屏数据后, 完成接近检测;
S306 , 根据接近检测结果, 判断是否检测到第一终端 100的接近, 是则转 向 S308 , 否则转向 S310;
S310 , 不存在第一终端 100的接近, 则转向 S302 , 重新进行下一次触摸检 测和接近检测等;
S308 , 通过第二子单元 212接近检测结果判断第一终端 100是否位于其 中, 是则转向 S314 , 否则转向 S312 ;
S312 , 确定第一终端 100与第二终端 200的距离小于等于预设距离后, 通 过某种手段 (如标识符等) 提示用户将第一终端 100移动到第二子单元 212 ; 转向 S302 ; S314 , 第二终端 200通过第二子单元 212与第一终端 100进行通信 处理。
如图 5-1所示, 在本发明的实施例中, 第二终端 200的第二近场通信区域 210可分为两块, 即非通信区域的第一子单元 21 1 和通信区域的第二子单元 212。 与图 2不同的是, 第二子单元 212具有独立的电极通道(典型如 ΥΓΥ^ 为驱动通道, 为感应通道, 应当理解的是, 每个通道也可以同时兼有 驱动功能和感应功能) 。 也就是说, 第一子单元 211中的电极通道并没有覆 盖到第二子单元 212上,第二终端 200的第二近场通信区域 210相当于由两 个相互组合的电极区组成, 由此, 可以进一歩减小第二近场通信区域 210 与第一近场通信区域 110进行通信的区域的面积, 以提升通信质量。
如图 5-1所示, 在触摸检测时, 同时控制第一子单元 211和第二子单元 212中的驱动通道和感应通道, 分别获取两个电极区的数据, 然后对两个电 极区的数据进行拼接处理得到第二近场通信区域 210的数据,用于对第二近 场通信区域 210 的触摸处理。 在数据近场通信时, 仅需要控制第二子单元 212中的驱动通道和感应通道, 得到第二子单元 212的数据用于对第二近场 通信区域 210的通信处理。 具体地, 在进行第一阶段检测的触摸扫描时, 同 时对第一子单元 211和第二子单元 212中的所有通道进行扫描,并将两个电 极区的数据组合起来, 生成整个第二近场通信区域 210的数据。 例如, 在第 一阶段触摸检测时可以得到如表 1和表 2所示的两部分数据:
其中 Α(ΓΑ10、Β(ΓΒ10、Α' (Γ Α' 2……分别表示每个检测节点的采样数据。 典型如 Α(ΓΑ7表示 X。和 ΥΓΥ7的节点处理数据, A' (Γ A' 2表示 。与 。的 节点采样数据, 依此类推。

表 1为第一子单元 211的采样数据
Figure imgf000012_0002
表 2为第二子单元 212的采样数据 然后, 将表 1和表 2所示的数据组合起来, 计算出如表 3所示的整个第 二近场通信区域 210的数据。 由此, 可以完成对第二近场通信区域 210进行 触摸检测的数据采集流程。
应当理解的是, 如果需要通过整屏进行接近检测, 则可以依照上述触摸 检测类似的处理方式, 完成第一阶段的接近检测数据采集流程; 如果仅需要 对第二子单元进行接近检测,则仅对指定第二子单元 212的电极通道进行扫 描, 完成接近检测的数据采集处理。
Figure imgf000013_0002
Figure imgf000013_0001
在进行第二阶段检测的通信扫描时,仅对指定区域的电极通道进行扫描, 即图 5中, 仅对 Y Yi。和 。〜 2组成的区域进行扫描, 此时
对第二近场通信区域 210的通信处理。
图 5-2为强调中第二子单元 212 (省略图 5中第二子单元 211相关通道) 相关走线的结构示意图;
如图 3-1, 没有进行硬件分割时, 第二近场通信区域 210分别从 Y/X通 道的一端引出外围走线; 如图 5-1和图 5-2, 通过硬件分割方式, 分别在 Y 末端和 X末端截取一段, 组成第二子单元 212 ; 其中第二子单元 212从屏体 的一端走线, 如图中 ΥΓΥ。和 。 12; 第一子单元 211从屏体另一端走线, 如图中 ΥΓΥ7和 ΧΓ 。 在第一阶段检测阶段, 触摸检测时所有的通道 (包括 第一子单元 211和第二子单元 212 ) 均参与检测, 接近检测时所有通道 (包 括第一子单元 211和第二子单元 212 )或第二子单元 212内的通道参与检测; 而在第二阶段, 只有第二子单元 212内 Υ和 X通道参与近场通信, 从而达到 减小整体接收面积的作用。
在通信阶段时, 仅对图中指定第二子单元 212的通道进行扫描接收, 从 而提高了通信质量。
本发明实施例的近场通信系统, 通过采用硬件分割的方式, 将第二终端 的近场通信区域中的指定区域作为专用的通信区域,让其具有独立的电极通 道, 在第二终端检测到的第一终端接近时, 通过该指定区域和第一终端进行 数据传输。 由此, 可以进一歩减少数据传输中信号衰减和外界干扰, 提高了 通信质量。
图 6是根据本发明再一个实施例的近场通信系统的结构示意图。如图 6所 示,该近场通信系统包括第一终端 100和第二终端 200,其中,第一终端 100 包括:第一近场通信区域 110,第二终端 200包括:第二近场通信区域 210、 第一子单元 21 1和第二子单元 212。
具体地,第一终端 100具有第一近场通信区域 110,其中,第一终端 100 可为手机。
第二终端 200具有第二近场通信区域 210, 其中, 第二终端 200可为笔 记本电脑、 掌上电脑、 电视或者显示屏等, 第二近场通信区域 210具有第一 子单元 211和第二子单元 212, 第一子单元 21 1和第二子单元 212, 或者仅 仅是第二子单元 212用于检测第一近场通信区域 110与第二近场通信区域 210之间的距离是否小于等于预设距离, 第二子单元 212用于在第一近场通 信区域 1 10与第二近场通信区域 210之间的距离小于等于预设距离时,与第 一近场通信区域 1 10建立通信, 其中, 第一近场通信区域 110和第二近场通 信区域 210的第二子单元 212通过近场通信的方式进行通信。
在本发明的实施例中, 如果可以利用整屏进行接近检测, 第二近场通信 区域 210的第二子单元 212具有提示标识。当第二终端 200在判断第一近场 通信区域 110与第二近场通信区域 210之间的距离小于等于预设距离时,发 出将第一近场通信区域 110放置至第二子单元 212的提示。 具体而言, 如图 7所示, 在第二终端 200靠近第一终端 100时, 可通过用户界面 (UI, User Interface ) 提示用户将第一终端 100放置在第二子单元 212上。 例如, 可 在第二终端 200的第二子单元 212上(例如中间位置, 或者右下角)弹出近 场通信标识,显示给用户以进行提示。除了弹出近场通信标识提示用户以外, 在弹出近场通信标识的同时还可控制第二子单元 212进行闪烁,以进一歩提 示用户。
本发明实施例的近场通信系统, 通过在第二近场通信区域的第二子单元 中显示提示标识, 用户能够在任意位置将第一终端和第二终端进行接触, 同 时由第二子单元给予用户提示到固定位置进行通信, 由此, 可以提供一种友 好的交互方式, 提升了用户体验。 为了实现上述实施例, 本发明还提出一种终端。
图 8是根据本发明一个实施例的终端的结构示意图。如图 8所示,终端 200 包括近场通信区域 210, 其中, 近场通信区域 210包括第一子单元 211和第 二子单元 212。
具体地, 终端 200具有近场通信区域 210, 其中, 终端 200可为笔记本 电脑、 掌上电脑、 电视或者显示器等, 其它终端可为手机等。 近场通信区域 210具有第一子单元 211和第二子单元 212, 第一子单元 211和第二子单元 212,或者仅仅是第二子单元用于检测近场通信区域 21与其它终端的近场通 信区域之间的距离是否小于等于预设距离,第二子单元 212用于第一子单元 211检测近场通信区域 210与其它终端的近场通信区域之间的距离小于等于 预设距离时, 与其它终端的近场通信区域建立通信。 其中, 第二子单元 212 与其它终端的近场通信区域通过近场通信的方式进行通信。上述检测近场通 信区域 210 与其它终端的近场通信区域之间的距离是否小于等于预设距离 均可通过现有技术实现, 为了避免冗余, 此处不再详细介绍。
具体而言,终端 200相对于其它终端而言具有较大面积的近场通信区域 210 (例如大于 10英寸) 。 例如, 终端 200为平板电脑, 其它终端为手机; 或者终端 200为笔记本电脑, 其它终端为掌上电脑等。 例如, 终端 200的近 场通信区域 210为笔记本电脑的显示屏,其它终端的近场通信区域为手机的 显示屏, 或者终端 200的近场通信区域 210为触摸板, 其它终端的近场通信 区域为手机的显示屏等。
如图 3-1所示, 终端 200的近场通信区域 210中可具有第一子单元 211 和第二子单元 212。 具体而言, 可采用软件分割的方式将近场通信区域 210 划分为大小不同的两个区域, 即第一子单元 211 (虚线框以外区域) 和第二 子单元 212 (虚线框内区域) 。 应当理解的是, 第二子单元 212的面积小于 第一子单元 211 的面积。 在检测到其它终端的近场通信区域接近终端 200 的近场通信区域 210时,通过第二子单元 212和其它终端的通信体建立通信。 其中, 当第二子单元 212与其它终端的近场通信区域进行通信时, 近场通信 区域 210中的第一子单元 211 (其中的全部或部分通道) 停止工作。
具体的, 停止工作主要指通道保持对其他通道干扰较小的状态, 如断开 (悬浮) 状态或直流固定电平状态, 尤其指保持直流固定电平状态。
进一歩而言,可将其它终端和终端 200之间的通信过程拆分为两个部分, 即接近检测和数据通信; 接近检测是数据通信的准备阶段。 一般地, 触摸检 测和接近检测分时进行, 接近检测成功后才进入数据通信阶段。可以将触摸 检测 +接近检测称之为第一阶段检测, 将近场通信称之为第二阶段检测。 以 下主要论述触摸检测, 接近检测的处理方式与触摸检测类似。
接近检测的目的是使终端 200感知是否存在与终端 200通信的其它终端, 由于此时终端 200无需和其它终端进行数据传输,因此对通信质量的要求较 低。
具体地, 利用通道切换的方式, 可实现终端 200 的近场通信区域 210 中不同区域的触摸检测和近场通信。如图 3-1所示, ΥΓΥ7为纵向通道, ΧΓ 为横向通道(典型如 ΥΓΥ。为驱动通道, 为感应通道; 应当理解的是, 也可以一个通道同时兼有驱动功能和感应功能,检测通道主要指带有感应功 能的电极通道) 。 对于 Υ。〜Υ7为驱动通道, ΧΓ 为感应通道的近场通信区域 210来说, 在对近场通信区域 210进行第一阶段检测的触摸扫描时, 应当对 近场通信区域 210中的所有驱动通道和感应通道均进行扫描。也就是说, 不 仅对第一子单元 211中的所有驱动通道和感应通道, 而且对第二子单元 212 中的所有驱动通道和感应通道进行扫描。此时将得到的数据用于对近场通信 区域 210的触摸处理。 应当理解的是, 如果需要通过整屏进行接近检测, 则 可以依照上述触摸检测类似的处理方式, 完成第一阶段的接近检测; 如果仅 需要对第二子单元进行接近检测,则仅对指定第二子单元 212的所有驱动通 道和部分感应通道 (如图 3 中虚线区域中的通道 ΧΓ ) 进行扫描, 完成接 近检测处理。
在对近场通信区域 210进行第二阶段的通信扫描时,仅对指定第二子单 元 212的所有驱动通道和部分感应通道 (图 3中虚线区域中的通道 ΧΓ ) 进行扫描, 此时得到的数据用于对近场通信区域 210的通信处理。 由此, 仅 通过指定区域 (即第二子单元 212 ) 和其它终端进行通信的话, 终端 200用 于接收有效信号的面积保持不变, 而用于整体接收的面积减小, 因此, 提高 了信号的通信质量。
应当理解的是, 如果终端 200中 ΧΓΧ9同时兼有驱动和感应功能, 在数 据传输时还可以仅使用第二子单元 212 内的 ΧΓΧ9来进行驱动和接收, 由此 可以节省终端的电量。
本发明实施例的终端, 将终端的近场通信区域中的指定区域作为专用的 通信区域, 在终端检测到其它终端接近时, 通过该指定区域和其它终端进行 数据传输。由此,可以减少数据传输中信号衰减和外界干扰,提高了通信质量。 图 9是根据本发明一个具体实施例的终端的结构示意图。 如图 9所示, 终 端 200包括近场通信区域 210,其中,近场通信区域 210包括第一子单元 211、 第二子单元 212。
具体地,近场通信区域 210还可包括第一子单元 211和第二子单元 212, 第一子单元 211和第二子单元 212, 或者仅仅是第二子单元 212用于检测终 端 200的近场通信区域 210与其它终端的近场通信区域之间的距离是否小于 等于预设距离。第二子单元 212用于在检测到近场通信区域 210与其它终端 的近场通信区域之间的距离小于等于预设距离时,与其它终端的近场通信区 域建立通信。
如图 5-1所示, 在本发明的实施例中, 终端 200的近场通信区域 210可分 为两块, 即非通信区域的第一子单元 211和通信区域的第二子单元 212。 第二 子单元 212具有独立的电极通道 (典型如 ΥΓΥ。为驱动通道, 为感应 通道, 应当理解的是, 每个通道也可以同时兼有驱动功能和感应功能, 检测 通道主要指带有感应功能的电极通道) 。 也就是说, 第一子单元 211中的电 极通道并没有覆盖到第二子单元 212上,终端 200的近场通信区域 210相当 于由两个相互组合的电极区组成, 由此, 可以进一歩减小终端 200的近场通 信区域 210与其它终端的近场通信区域进行通信的区域的面积,提升通信质 进一歩而言,终端 200在没有检测到近场通信区域 210与其它终端的近 场通信区域之间的距离小于等于预设距离的时候,需要分时对其它终端的近 场通信区域进行触摸检测和接近检测。 可以将触摸检测 +接近检测称之为第 一阶段检测, 将近场通信称之为第二阶段检测。
在触摸检测时,同时控制第一子单元 211和第二子单元 212中的驱动通 道和感应通道, 分别获取两个电极区的数据, 然后对两个电极区的数据进行 拼接处理得到近场通信区域 210的数据,用于对近场通信区域 210的触摸处 理。 在近场通信时, 仅需要控制第二子单元 212中的驱动通道和感应通道, 得到第二子单元 212的数据用于对近场通信区域 210的通信处理。 具体地, 在进行第一阶段检测的触摸扫描时, 同时对第一子单元 211 和第二子单元 212中的所有通道进行扫描, 并将两个电极区的数据组合起来, 生成整个近 场通信区域 210的数据。例如, 在第一阶段触摸检测时可以得到如表 1和表 2所示的两部分数据: 其中 Α(ΓΑ10、Β(ΓΒ10、Α' (Γ Α' 2……分别表示每个检测节点的采样数据。 典型如 Α(ΓΑ7表示 X。和 Υ。〜Υ7的节点采样数据, A' (Γ A' 2表示 。与 。的 节点采样数据, 依此类推。

表 2为第二子单元 212的采样数据 然后, 将表 1和表 2所示的数据组合起来, 计算出如表 3所示的整个近 场通信区域 210的数据。 由此, 可以完成对近场通信区域 210进行触摸检测 的数据采集流程。
应当理解的是, 如果需要通过整屏进行接近检测, 则可以依照上述触摸 检测类似的处理方式, 可以完成第一阶段的接近检测数据采集流程; 如果仅 需要对第二子单元进行接近检测,则仅对指定第二子单元 212的电极通道进 行扫描, 完成接近检测的数据采集处理。

表 3为近场通信区域 210整个屏幕的组合数据 在进行第二阶段检测的通信扫描时,仅对指定区域的电极通道进行扫描, 即图 5-1中, 仅对 Y Yi。和 。〜 2组成的区域进行扫描, 此时得到的数据用 于对第二近场通信区域 210的通信处理。 由此, 通过采用硬件分割的方式, 将终端 200的近场通信区域 210中的指定区域作为专用的通信区域,让其具 有独立的电极通道, 在终端 200检测到其它终端接近时, 通过该指定区域和 其它终端进行数据传输。 由此, 可以进一歩减少数据传输中信号衰减和外界 干扰, 提高了通信质量。
在本发明的实施例中, 可以对整屏进行接近检测, 近场通信区域 210 的第二子单元 212具有提示标识。当终端 200在判断近场通信区域 210与其 他终端的近场通信区域之间的距离小于等于预设距离时,发出将其它终端的 近场通信区域放置至第二子单元 212的提示。 具体而言, 如图 7所示, 其它 终端靠近终端 200时, 终端 200可通过用户界面 (UI, User Interface ) 提 示用户将其它终端放置在第二子单元 212上。例如, 可在终端 200的第二子 单元 212内或其附近(例如中间位置, 或者右下角)弹出近场通信标识, 显 示给用户以进行提示。 除了弹出近场通信标识提示用户以外, 在弹出近场通 信标识的同时还可控制第二子单元 212进行闪烁,以进一歩提示用户。由此, 通过在近场通信区域 210的第二子单元 212中显示提示标识,用户能够在任 意位置将其它终端和终端 200进行接触,同时由第二子单元 212给予用户提 示到固定位置进行通信, 可以提供一种友好的交互方式, 提升了用户体验。
