400 操作方法
S410-S490 步骤 具体实施方式
图 1及图 2为本发明一实施例的身份辨识装置 100于不同操作下的示意图。身份辨识 装置 100包含发光模块 110、 光感测模块 120、 脉搏扫描单元 130、 指纹扫描单元 140及 控制器 150。在图 1及图 2中, 发光模块 110可发出第一入射光 L1及第二入射光 L2至对 象 160。 光感测模块 120包含多个感光元件 122, 可用以根据对象 160反射第一入射光 L1 的第一反射光 Rl, 产生多个第一光电流 II, 及根据对象 160反射第二入射光 L2的第二反 射光 R2, 产生多个第二光电流 12。 其中多个感光元件 122中的每一感光元件是于相异的 时间感测第一反射光 R1及第二反射光 R2。在图 1的实施例中, 光感测模块 120还包含了
多条栅极线 Gn、 多条读出线 Lm以及栅极驱动电路 124, 其中 n及 m为正整数。 每一栅极 线 0是耦接于多个感光元件 122中位于第 n行的感光元件 122, 而每一条读出线 Lm则是 耦接于多个感光元件 122中位于第 m行的感光元件 122, 而多条栅极线 Gn及多条读出线 Lm是彼此交错排列。 当感光元件 122所连接的栅极线(^为导通时, 导通的读出线 Lm即 可读出其对应感光元件 122所产生的光电流。如此一来, 在栅极驱动电路 124轮流导通多 条栅极线 Gn时, 读出线 Lm即可依序读出栅极线 Gn所连接的第 m行感光元件 122所产生 的光电流。 脉搏扫描单元 130耦接于光感测模块 120, 并用以接收并根据多个第一光电流 II产生对象 160的电流变化数据。 指纹扫描单元 140耦接于光感测模块 120, 并用以接收 并根据多个第二光电流 12产生对象 160的指纹特征。控制器 150耦接于发光模块 110、脉 搏扫描单元 130及指纹扫描单元 140。 控制器 150可用以控制发光模块 110发出第一入射 光 Ll, 并于检测到对象 160的电流变化数据符合脉搏跳动特征时, 控制发光模块 110发 出第二入射光 L2, 并根据对象 160的指纹特征判断对象 160是否通过身份辨识。
此外,为了避免光电流同时流向脉搏扫描单元 130及指纹扫描单元 140而导致电路不 稳定的状况,身份辨识装置 100还包含第一组开关 170及第二组开关 172。第一组开关 170 耦接于多条读出线 Lm及脉搏扫描单元 130之间,用以控制多条读出线 Lm与脉搏扫描单元
130之间的电性连接。 第二组开关 172则是耦接于多条读出线 Lm及指纹扫描单元 140之 间, 用以控制多条读出线 Lm与指纹扫描单元 140之间的电性连接。
于本发明的一实施例中, 光感测模块 120中的感光元件、 多条栅极线 Gn、 多条读出 线 Lm、 栅极驱动电路 124, 以及第一组开关 170、 第二组开关 172 皆可利用薄膜晶体管 (thin-film transistor)的工艺,制作于透明板上,而发光模块 110可置于光感测模块 120的下 方,与光感测模块 120相迭。发光模块 110所发出的第一入射光 L1及第二入射光 L2可穿 过光感测模块 120到达对象 160, 如此即可减少身份辨识装置 100所需的空间。
在图 1中,控制器 150控制发光模块 110发出第一入射光 L1至对象 160,若对象 160 为使用者的手指, 则因为使用者的脉搏, 将导致使用者的手指透光率会随着血液流动而改 变, 如在心脏收缩时, 血管中的血液量增加, 因此透光率降低, 而当心脏舒张时, 血管中 的血液量则会减少, 导致透光率增加。 如此一来, 多个感光元件 122根据感测对象 160反 射第一入射光 L1的第一反射光 R1所产生的多个第一光电流 II也会随之变化。 此时即可 导通第一组开关 170并截止第二组开关 172使得脉搏扫描单元 140可接收根据多个第一光 电流 II的大小变化产生对象 160的电流变化数据。 而控制器 150即可判断电流变化数据 是否符合脉搏跳动特征。也即, 将电流变化数据中显示第一光电流的变化频率及第一光电
流变化的大小, 与生物脉搏的频率及变化量来比较, 即可作为电流变化数据是否符合脉搏 跳动特征的依据。在本发明的一实施例中, 身份辨识装置 100是利用栅极驱动电路 124来 控制第一组开关 170及第二组开关 172的截止及导通, 然而本发明并不以此为限, 在本发 明的其他实施例中,也可利用控制器 150来控制第一组开关 170及第二组开关 172的截止 及导通。
若电流变化数据符合脉搏跳动特征,则控制器 150可控制发光模块 110发出第二入射 光 L2以辨识对象 160的指纹特征, 如图 2所示。 栅极驱动电路 124可轮流导通多条栅极 线 0及读出线 Lm, 以依序读出每一个感光元件 122根据对象 160反射第二入射光 L2的 第二反射光 R2所产生的第二光电流 12。而对象 160表面上的纹路会造成每个感光元件 122 感测到不同大小的第二反射光 R2, 并产生大小不同的第二光电流 12。 此时即可导通第二 组开关 172并截止第一组开关 170使得指纹扫描单元 140可接收并根据这些大小不同的第 二光电流 12来产生对象 160的指纹特征,而控制器 150即可根据指纹特征来判断对象 160 表面上的纹路是否为使用者的指纹, 并依此判断对象 160是否通过身份辨识。 于一实施例 中, 对象 160的指纹特征包含了对象 160的纹路空间分布及纹路深浅, 而控制器 150即可 根据对象 160的指纹特征与事先存储的使用者指纹数据比对, 若两者具有相同的特征, 则 表示对象 160为使用者的手指, 因此判断对象 160通过身份辨识。
此外, 由于血液是红色的, 因此第一入射光 L1可为红外光, 以增加辨识脉搏的准确 度。 而由于第一入射光 L1的强度必需足以穿透对象 160的表面以检测其内部血管穿透率 的变化量, 而为能清楚表现对象 160表面上的纹路变化, 第二入射光 L2也可为红外光, 且第二入射光 L2的强度则不宜过强, 以免无法判断表面纹路的细节。 在本发明一实施例 中, 第一入射光 L1的强度可大于第二入射光 L2的强度。再者, 由于对象 160的透光率变 化是与对象 160的脉搏有关, 因此对象 160上各处的透光率变化皆相似, 因此第一组开关 170可同时导通 M条读出线 Lm与脉搏扫描单元 130间的电性连接,使得脉搏扫描单元 130 可同时接收多个第一光电流的大小变化, 而无须逐一扫描, 其中 M为小于或等于 m的正 整数。 如此一来, 即可使脉搏扫描单元 130的光电流变化亮增加,可使准确性上升,也可减 少后端放大电路是倍率, 同时噪声也会因放大倍率减少而减少。
根据上述本发明的实施例,个人电子装置可利用同一个光感测模块来检测对象的脉搏 信息及其指纹特征, 并依据对象的脉搏信息及指纹特征来判别使用者的身份, 来增强对个 人电子装置的保护, 而无须额外增加线路来感测脉搏, 并简化个人电子装置的设计。
图 3为本发明另一实施例的身份辨识装置 200的示意图。身份辨识装置 200与身份辨
识装置 100具有类似的架构,其差别在于身份辨识装置 200可利用解多路复用器 280来取 代身份辨识装置 100中第一组开关 170及第二组开关 172的功能。解多路复用器 280耦接 于多条读出线 Lm、 脉搏扫描单元 130及指纹扫描单元 140, 并用以控制多条读出线 Lm与 脉搏扫描单元 130及多条读出线 Lm与指纹扫描单元 140之间的电性连接, 以使脉搏扫描 单元 130和指纹扫描单元 140于不同时段内, 分别接收多个第一光电流 II及多个第二光 电流 12。如此一来, 身份辨识装置 200中的脉搏扫描单元 130及指纹扫描单元 140即可放 置于光感测模块 120的同一侧, 并可增加身份辨识装置 200于设计上的弹性。在本发明的 一实施例中, 身份辨识装置 200可利用控制器 150来控制解多路复用器 280。
图 4及图 5为本发明另一实施例的身份辨识装置 300于不同操作下的示意图。身份辨 识装置 300包含发光模块 310、 光感测模块 320、 脉搏扫描单元 330、 指纹扫描单元 340、 控制器 350、 解多路复用器 380、 多路复用器 390、 第一组无源元件 392、 第二组无源元件 394及放大器 396。 在图 4及图 5中, 发光模块 310可发出第一入射光 L1及第二入射光 L2至对象 360。 光感测模块 320包含多个感光元件 322、 多条栅极线 Gn及多条读出线 Lm 以及栅极驱动电路 324,其中 n及 m为正整数。每一栅极线 0是耦接于多个感光元件 322 中位于第 n行的感光元件 322, 而每一条读出线 Lm则是耦接于多个感光元件 322中位于 第 m行的感光元件 322, 而多条栅极线 Gn及多条读出线 Lm是彼此交错排列。 当栅极驱动 电路 324轮流导通栅极线 Gn时, 读出线 Lm可依序读出与栅极线 Gn所连接的第 m行感光 元件 322所产生的光电流。第一组无源元件 392耦接于多路复用器 390及多条读出线 Lm, 而第二组无源元件 394耦接于多路复用器 390及多条读出线 Lm。 放大器 390耦接于解多 路复用器 380及多路复用器 390。
在图 4中,控制器 350控制发光模块 310发出第一入射光 L1至对象 360,若对象 360 为使用者的手指, 则对象 360的透光率会随着使用者血液流动而改变。 多个感光元件 322 即可根据对象 360反射第一入射光 L1的第一反射光 R1所产生的多个第一光电流 II。 由 于第一光电流 II中可能含有许多环境造成的噪声,因此控制器 350可控制多路复用器 390 导通第一组无源元件 392与放大器 396之间的电性连接,使得放大器 396可利用第一组无 源元件 392来放大多个第一光电流 II 中具有特定频段的电流, 以减少噪声对身份辨识装 置 300的影响。 同时, 控制器 350可控制解多路复用器 380, 使脉搏扫描单元 330接收并 根据放大器 396放大多个第一光电流 II 中具有特定频段的电流, 来产生对象 360的电流 变化数据。 而控制器 350即可判断电流变化数据是否符合脉搏跳动特征。
若控制器 350判断对象 360具有脉搏,则控制器 350可控制发光模块 310发出第二入
射光 L2以辨识对象 360的指纹特征, 如图 5所示。 光感测模块 320可轮流导通多条栅极 线 0及读出线 Lm, 以依序读出每一个感光元件 322根据对象 360反射第二入射光 L2的 第二反射光 R2所产生的第二光电流 12。 由于第二光电流 12的强度较弱, 且所欲检测的纹 路特征不会随时间改变, 因此控制器 350可控制多路复用器 390 以导通第二组无源元件 394与放大器 396之间的电性连接, 使得放大器 396可利用第二组无源元件 394来产生多 个第二光电流 12的积分值。 同时, 控制器 350可控制解多路复用器 380, 使指纹扫描单元 340接收并根据放大器 396所产生多个第二光电流 12的积分值,来产生对象 360的指纹特 征, 以减少噪声对身份辨识装置 300的影响, 并突显对象 360表面纹路深浅所造成的多个 第二光电流 12间的差异。 而控制器 350即可根据对象 360的指纹特征来判断对象 360是 否通过身份辨识。
根据上述的实施例,通过解多路复用器 380及多路复用器 390来控制放大器 396与第 一组无源元件 392、 第二组无源元件 394、 脉搏扫描单元 330即指纹扫描单元 340之间的 电性连接, 即可在不同时段中利用放大器 396分别实现放大滤波器及积分器的功能, 而可 使脉搏扫描单元 330接收多个第一光电流 II 中具有特定频段的电流以产生对象 360的电 流变化数据, 并使指纹扫描单元 340接收多个第二光电流 12的积分值以产生对象 360的 指纹特征。 如此一来, 即可减少身份辨识装置 300所需的硬体元件, 并可增加于设计上的 弹性。
于上述实施例中, 光感测模块 120及 320 皆可利用低温多晶硅工艺 (low temperature poly-silicon, LTPS)制造于透明板上。 而无源元件 392、 无源元件 394、 多路复用器 390及 放大器 396也可利用低温多晶硅工艺 (low temperature poly-silicon, LTPS)与光感测模块 320 一同制造于透明板上, 以简化身份辨识装置 300的设计, 并可减少身份辨识装置 300所需 的空间。
根据上述本发明的实施例,个人电子装置可利用同一个光感测模块检测对象的脉搏信 息及其指纹特征, 并依据对象的脉搏信息及指纹特征来判别使用者的身份, 来增强对个人 电子装置的保护, 而无须额外增加线路来感测脉搏, 并简化个人电子装置的设计。
图 6为本发明一实施例的身份辨识装置 100的操作方法 400的流程图。身份辨识装置 100的操作方法 400包含以下步骤:
S410: 使发光模块 110发出第一入射光 L1至对象 160;

S480: 根据指纹特征判断对象 160 是否通过身份辨识, 若通过身份辨识则进入步骤 S490, 否则回到步骤 S410;
S490: 结束。
其中每一个感光元件 122是于相异的时间感测第一反射光 R1及第二反射光 R2。且根 据本发明的一实施例, 第一入射光 L1是为红外光。
根据上述本发明的实施例的操作方法,即可利用同一个光感测模块检测对象的脉搏信 息及其指纹特征, 并依据对象的脉搏信息及指纹特征来判别使用者的身份, 来增强对个人 电子装置的保护, 而无须额外增加线路来感测脉搏, 并简化个人电子装置的设计。
