以下将参照相关附图， 说明依本发明优选实施例的一种视觉接口装置及数 据传输***， 其中相同的元件将以相同的元件符号加以说明。
请参照图 1及图 2所示， 其中， 图 1为本发明优选实施例的一种数据传输 ***的功能方块示意图， 而图 2为图 1的接口模块 22的功能方块示意图。
如图 1所示， 本发明的数据传输***包括一操作装置 1 以及一视觉接口装 置 2，互相耦接，并例如可通过电磁耦合（例如电容或电感）的方式而电性耦接， 借此可传送数据或档案， 故为不须接线的数据或档案的传输， 还可称为无线方 式的数据或档案的传输。
操作装置 1可例如为一接收装置（例如为卡片阅读机或门禁***等）、 或一 芯片卡、 或为另一个具有视觉接口装置的电子装置、 或为具有执行其它功能的 电子装置。 另外， 操作装置 1及视觉接口装置 2内可分别具有处理控制***、 储存***或传送***等等功能性子***。 在此， 「***」 可通过硬件、 软件、 或 韧体、 或其组合所构成。
视觉接口装置 2包括一控制模块 21及一接口模块 22。 其中， 控制模块 21 可包括视觉接口装置 2 的核心控制组件， 并例如可包括至少一个中央处理器 ( central processing unit, CPU) 及一内存， 或包括其它控制硬件、 软件或 韧体， 控制模块 21可为一***主电路板。 另外， 接口模块 22可具有一驱动单 元 221及一显示面板 222。其中， 驱动单元 221可包括驱动显示面板 222的驱动 电路， 而显示面板 222可具有像素矩阵， 并可为一有源式矩阵（active matrix ) 或为一无源式矩阵式 （passive matrix ) 0 于此， 以有源式矩阵为例， 并例如可 为液晶显示面板、 有机发光二极管面板、 发光二极管面板、 电泳显示面板、 触 控显示面板、 或 MEMS显示面板等的矩阵基板。
请参照图 3所示， 其为一实施例的接口模块 22的功能方块示意图。 在此， 接口模块 22的显示面板 222以液晶显示面板为例。
在本实施例中， 显示面板 222为一液晶显示面板， 包括多个行电极、 多个 列电极及多个像素电极， 且所述行电极与所述列电极可交错设置 （图未显示）。 另外， 显示面板 222更可包括多个晶体管 （图未显示）， 且所述晶体管分别与所 述行电极、 所述列电极、 以及所述像素电极电性连接。 于此， 所述行电极以多 个扫描线 ^为例， 所述列电极以多个数据线 Dn为例， 当然也可以是所述行电极 为多个数据线 Dn， 而所述列电极为多个扫描线 Sm。
控制模块 21可将一显示数据 DD及一传输数据 TD传送到驱动单元 221， 而 驱动单元 221可接收处理后再将一画面数据 SD及一耦合数据 CD传送到显示面 板 222。 其中， 画面数据 SD及耦合数据 CD可分别对应含有显示数据 DD及传输 数据 TD的信息。 另外， 显示数据 DD及传输数据 TD可分别由视觉接口装置 2的 内部指令或外部指令所产生， 且其来源可由视觉接口装置 2 内的内存取得， 或 可由外部装置传输取得， 于此， 并不加以限制。 其中， 显示数据 DD可为显示面 板 222 的图框画面的灰阶数据， 而传输数据 TD 可为一数字数据串流 （data stream)或数字档案串流， 并可为触控信息、 指令信息、 识别信息、 交易信息、 广告信息、 优惠信息、 档案信息或其它信息等。 此外， 驱动单元 221 的处理可 包括串-并转换（series- to- paral lel conversion) ,加码、加密、加入档头（包 括有数据大小、 检查码、 序号、 追踪数据）、 传送起始标记及或结束标记等。 与 一般通讯传输模式不同在于， 接口模块 22可以利用显示面板 222上的不同电极 同时作为传输的发射源 （多通讯管道）， 以进行数据传输。 这些通讯管道间可以 利用空间隔离或调变技术等以同时传送并减少彼此间干扰。 需注意的是， 数据 的串-并转换方式可以是依序或为交错、 或是两者的组合。 于此， 画面数据 SD 及耦合数据 CD是表示有两种不同目的的数据传送到显示面板 222， 而非表示其 信号。 以液晶显示面板为例， 画面数据 SD是代表包括扫描信号 （Y方向驱动） 及数据信号 （X方向驱动） 两种， 而耦合数据 CD所代表的信号可以是独立的扫 描信号或数据信号、 或是并于画面数据 SD 的扫描信号、 或是并于画面数据 SD 的数据信号中等等不同态样。
控制模块 21可产生一第一标记以标示显示数据 DD,并可产生一第二标记以 标示传输数据 TD。换言之， 为了使驱动单元 221可区别显示数据 DD为显示用的 画面数据 SD， 而传输数据 TD为传输用的耦合数据 CD, 故控制模块 21可产生包 括至少一个控制信号或至少一个数据标记格式的不同标记加入显示数据 DD及传 输数据 TD， 以使驱动单元 221区别所述输入数据用以显示的画面数据 SD， 或为 用以耦合的耦合数据 CD。 其中， 驱动单元 221可依据具有第一标记的显示数据 DD输出画面数据 SD,以使显示面板 222显示一图框画面的至少部分画面。另外， 驱动单元 221可依据具有第二标记的传输数据 TD输出需要通过显示面板 222的 至少一个电极耦合到操作装置 1的耦合数据 CD。 其中， 显示面板 222的电极可 为一独立电极 （可为一条或多条电极）， 并独立于显示面板 222的像素矩阵外， 或为显示面板 222上的像素矩阵的多个行电极或多个列电极的至少其中之一。 当操作装置 1于显示面板 222的一显示面上操作时， 至少部分耦合数据 CD或全 部的耦合数据 CD可从显示面板 222耦合到操作装置 1。 于此， 操作装置 1于显 示面板 222的显示面上操作是指操作装置 1靠近或接触显示面板 222的显示面。 另外， 通过显示面板 222 的独立电极、 所述行电极或所述列电极的至少其中之 一， 将部分的耦合数据 CD耦合到操作装置 1。 此外， 同时通过多功能显示及传 输数据的接口模块 22， 可以整合显示数据 DD及传输数据 TD, 并用单一连接端 口以连接控制模块 21与接口模块 22，进而可简化视觉接口装置 2及数据传输系 统的整体设计。
值得注意的是， 上述除了使用第一标记及第二标记来区别显示数据 DD与传 输数据 TD夕卜， 还可使用时间标示来区别， 例如控制模块 21可固定于不同时间 分别将显示数据 DD及传输数据 TD分别传送到驱动单元 221，以利用时间差别来 区别显示数据 DD与传输数据 TD。 例如控制模块 21可与驱动单元 221约定以下 的交谈法则， 于一画面开始到最后一条扫描线结束之间 （第一时间） 传送的数 据为显示数据 DD， 而于最后一条扫描线结束到下一个画面开始前 （第二时间） 传送的数据为传输数据 TD;或是每一条扫描时间先传送传输数据 TD (第一时间）， 再传送显示数据 DD (第二时间） 等， 借此使驱动单元 221可区别那一种数据用 以显示图框画面的画面数据 SD， 而那一种数据用以传输到操作装置 1的耦合数 据 CD。
如图 3所示， 驱动单元 221可包括一控制电路与一驱动电路， 以液晶显示 面板为例， 此驱动电路包括一数据驱动电路 （Data driver ) 与一扫描驱动电路 ( Scan driver ) , 而两者的时序控制则由控制电路产生。 其中， 扫描驱动电路 与显示面板 222的扫描线 Sm电性连接， 数据驱动电路与显示面板 222的数据线 Dn电性连接。 而控制电路可将自外部接口所接收的显示数据 DD转换成画面数据 SD， 并包括产生扫描驱动电路及数据驱动电路所需的频率、 同歩信号及每一像 素所需的数据信号等。 由于驱动单元 221对于影像的显示驱动为已知技术， 于 此不再多作说明。
以数据线 Dn为例， 数据线 Dn (所述列电极） 除了可传送一般图框画面的画 面数据 SD外， 于此还可用以传送耦合数据 CD。 例如可将耦合数据 CD转换成一 高于画面数据 SD频率的信号并直接迭加于画面数据 SD的信号上， 或将耦合数 据 CD的信号穿插在画面数据 SD的信号之间传送， 并例如在所有扫描线 Sm扫描 完后在接续下一次画面扫描前的时间传送 （图框画面与图框画面之间的空档时 间）， 或是在一条扫描线 Sra扫描完成且在下一条开始扫描前传送， 或是在每一条 扫描线 描时间内通过缩短画面数据 SD并在传送画面数据 SD前传送等。
另外， 耦合数据 CD还可经由扫描线^传送， 例如转换成一不开启像素晶体 管的电平的信号等， 或是经由一非属数据线1)„与扫描线 ^的电极传送 （例如独 立电极传送）， 或是同时在数据线 1\与扫描线 ^上传送， 以加快传输速度， 又或 是将耦合数据 CD转成两个信号 (例如一正、 一负）， 同时传送到不同电极上 （如 数据线或扫描线），而操作装置 1通过同时接收此两个信号以还原出耦合数据 CD , 可提高传输的准确性等。
于此， 部分的耦合数据 CD的传送功能可通过控制电路与驱动电路（包括数 据驱动电路或扫描驱动电路） 来提供。
于传统中， 驱动单元 221对于影像的显示驱动， 在驱动电路中利用一移位 缓存器以将串流 （series ) 的数据转成一并流 （paral lel ) 的数据。 例如数据 驱动电路中利用移位缓存器将一个个输入的像素数据转换成 n条数据线的数据， 并在一扫描线时间同时输出。 另外， 扫描驱动电路中还利用一移位缓存器以将 前一笔输出位移到下一笔， 以达成循序扫描。 此为已知的方法。 在本实施例中， 数据驱动电路及扫描驱动电路的至少其中之一可具有一第一移位缓存器及一第 二移位缓存器 （图未显示）。 于此， 以耦合数据 CD经由数据线 Dn传送为例。 当 控制电路接收显示数据 DD及传输数据 TD并经处理后可得到画面数据 SD及耦合 数据 CD， 并例如可将画面数据 SD及耦合数据 CD分别对应传送到数据驱动电路 的第一移位缓存器及第二移位缓存器，以通过第一移位缓存器处理画面数据 SD, 并通过第二移位缓存器处理耦合数据 CD。 其中， 画面数据 SD可使显示面板 222 显示图框画面， 而耦合数据 CD可传送到显示面板 222的电极， 以通过电容或电 感耦合而传输到操作装置 1。
当画面数据 SD使显示面板 222显示的图框画面为多个时， 所述图框画面的 至少其中之一可含有准备将耦合数据 CD耦合到操作装置 1的讯息。 另外， 所述 图框画面的至少其中之一也可含有耦合数据 CD耦合到操作装置 1 的结果的讯 息。 换言之， 在显示面板 222开始传输耦合数据 CD前及传输结束后， 显示面板 222均可显示提示画面， 以提醒使用者注意。另外，在显示面板 222的传输期间， 显示面板 222还可以在显示画面中标示出用于传输的电极区域范围， 以方便操 作装置 1进行信号的耦合。
于此， 耦合以无线方式将数字信息（即 0或 1 ) 自视觉接口装置 2传输到操 作装置 1。 而操作装置 1接收自显示面板 222上传送的耦合数据 CD时， 操作装 置 1可通过所接收到的耦合数据 CD进行反向处理以得到传送的信息。 其中， 接 收数据的方式通过操作装置 1靠近或接触视觉接口装置 2的显示面板 222，以将 信号通过电磁作用耦合到操作装置 1。
另外， 若利用的是像素矩阵中的行电极或列电极来传送部分的耦合数据 CD 时， 则可与视觉接口装置 2的画面数据 SD分开于不同时间传送， 例如于一图框 画面传送结束后或于一图框画面传送开始前传送到操作装置 1。换言之，视觉接 口装置 2可于一个图框 （frame ) 画面结束后， 并于下一图框画面开始前， 或于 显示一个图框画面的期间，将耦合数据 CD开始传送到操作装置 1。需注意的是， 若是利用于像素矩阵外的独立电极来进行耦合数据 CD的传送时， 则可不用与图 框画面传送的时间配合。
另外， 请同时参照图 3及图 4所示， 其中， 图 4为图 3中的相邻两条扫描 线 （行电极） 与相邻两条数据线 （列电极） 的信号示意图。 在此， 以每一列晶 体管被开启进行显示时同时可进行部分耦合数据 CD的传送为例来说明。 要注意 的是， 晶体管被开启与否并非必要， 还可在晶体管关闭状态下进行耦合数据 CD 的传送， 此时部分的耦合数据 CD可分别传送于数据线或扫描在线。 其中， 扫描 线可分别传送扫描信号并依序使每一列的晶体管开启， 而在每一列晶体管被开 启的时间中， 各数据线可分别传送部分的耦合数据 CD与画面数据 SD。
在本实施例中，在扫描线 送其扫描信号 SSw时，全部的数据线 Dn传送 部分的耦合数据 CDk-1 ;在扫描线 Sk传送其扫描信号 SSk时，全部的数据线 Dn传送 部分的耦合数据 CDk。在图 4中，部分的耦合数据
Figure imgf000010_0001
SDk不同电压电平方式标示的， 实施时还可以相同的电平进行。 如此， 数据线 Dn 随着扫描线 ^传送扫描信号时可分别传送耦合数据 CD，以将耦合数据 CD的至少 一部分耦合到操作装置 1。
需补充说明的是， 图 4中显示的部分的耦合数据 CDk、 0^虽显示为高电平 的 1， 不过只是示意， 当然， 也可以使用低电平的 0。 另外， 为了避免产生信号 的极性问题， 部分的耦合数据 CDk、 CDH的信号本身可采用无直流成分的交流信 号。 再者， 部分的耦合数据 CDK、 CDH可分别包括一个位的数据或是多个位的数 据， 于此并不加以限制。 除了如图 4中所有的数据线 1)„于同一图框时间中均传 送相同部分的耦合数据 CDK、 CDH的态样外， 各数据线也可分别传送不同部分的 耦合数据， 还可以数条数据线为一组来传送同一个部分的耦合数据， 例如数据 线 Dt Ds都传送第一部分的耦合数据 CD1 而数据线 D4〜D6都传送第二部分的耦 合数据 CD2 ; 同样的原则还可适用于扫描线所传送的部分的耦合数据。 此外， 为 了确保耦合数据 CD传送的正确性， 也可于不同的时间重复传送相同部分的耦合 数据 CD， 也就是说， 如果发现异常时可以再次进行相同部分的耦合数据 CD的传 送， 以确保操作装置 1接收数据的正确性。
此外， 上述的调变方式为振幅调变 （Ampl i tude Modulati on ) 技术， 即是 以振幅的高低来表示数字信号的 1或 0， 不过， 也可使用频率调变 （Frequency Modulation )技术来表示数字信号的 1或 0，例如可定义单位时间内有 5个上下 振幅的变化是为 1， 其余则为 0; 或者使用相移调变 （Phase Shi ft Modulat ion ) 技术，例如定义一个高准位加上一个低准位为 0， 而一个低准位加上一个高准位 则为 1。 于此， 其调变方式并不加以限制。 另外， 为避免邻近电极之间的干扰， 不同电极之间可以采用分时、 分频、 分码等技术。
因此， 当使用者拿着操作装置 1于视觉接口装置 2的显示面板 222上操作 时（例如碰触到显示面板 222或靠近显示面板 222)，耦合数据 CD可从显示面板 222的显示面通过电容或电感耦合到操作装置 1。 由于本实施例以数据线传送耦 合数据 CD为例， 因此各数据线作为电容耦合的其中一个电极， 而操作装置 1上 具有电容耦合的另一电极。 在操作装置 1通过电容耦合接收到所有的部分耦合 数据 CD后， 操作装置 1可将接收的所有部分耦合数据 CD加以组合， 以得到完 整的耦合数据 CD， 并例如可为一文本文件、 图片档案或一视听档案等等。例如， 当操作装置 1为一门禁控制单元时， 即可通过视觉接口装置 2的显示面靠近操 作装置 1操作时， 使操作装置 1接收由视觉接口装置 2传送的开门或锁门的信 息， 借此可解除门禁或上锁； 当视觉接口装置 2 为一公众显示广告牌 （publ ic display) , 而操作装置 1为一手机或其它个人装置时， 可通过将操作装置 1靠 近视觉接口装置 2 的显示面， 而将如广告信息、 优惠信息、 地理信息等等传送 到个人装置带走。
综上所述， 因本发明的数据传输***及其视觉接口装置的控制模块可将显 示数据及传输数据传送到接口模块的驱动单元， 而驱动单元接收处理后可分别 传送画面数据及耦合数据到接口模块的显示面板， 且当操作装置于视觉接口装 置上操作时， 至少部分的耦合数据可从显示面板耦合到操作装置。 借此， 视觉 接口装置除了可用以显示影像画面外， 也可将数据或档案等传输数据通过无线 耦合的方式传送到操作装置， 故本发明通过整合显示数据与传输数据可以简化 接口模块与控制模块的连接， 还可达成无线连接的传输功能而扩大视觉接口装 置的应用层面。
以上所述仅是举例性， 而非限制性。 任何未脱离本发明的精神与范畴， 而 对其进行的等效修改或变更， 均应包括在权利要求所限定的范围内。
