具体实施方式
下面详细描述本申请的实施例，所述实施例的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。
在本申请的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”“内”、“外”、“轴向”、“径向”、“周向”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。此外，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征。在本申请的描述中，除非另有说明，“多个”的含义是两个或两个以上。
在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本申请中的具体含义。
下面参考附图描述根据本申请实施例的电子设备100，其包括壳体组件110和适于对指纹识别区111内的指纹进行指纹识别的指纹识别组件。需要说明的是，指纹识别组件可以为基于光学原理，例如光的折射和反射原理来实现的指纹识别组件；当然，指纹识别组件也可以基于射频或声波传递原理。例如利用超声波的反射原理来实现的指纹识别。
具体地，利用光学原理识别指纹的装置，可以称为光学传感器，它主要是利用光的折摄和反射原理，将手指放在光学镜片上，手指在内置光源照射下，光从底部射向三棱镜，并经棱镜射出，射出的光线在手指表面指纹凹凸不平的线纹上折射的角度及反射回去的光线明暗就会不一样。用棱镜将其投射在电荷耦合器件上CMOS或者CCD上，进而形成脊线(指纹图像中具有一定宽度和走向的纹线)呈黑色、谷线(纹线之间的凹陷部分)呈白色的数字化的、可被指纹设备算法处理的多灰度指纹图像。
利用射频或声波传递原理识别指纹的装置，可以称为射频/超声波传感器，其原理与探测海底物质的的声纳类似，是靠特定频率的信号反射来探知指纹的具体形态的。这一类指纹模块最大的优点便是手指无需与指纹模块相接触，因而不会对手机的外观造成太大影响。超声检测原理是相同的，就是依靠反射波的时间差探知脊和谷的距离差，根据这个距离差 绘制出指纹图像。
如图1所示，指纹传感器可以利用光学结构形成，例如一个或多个光发送器和一个或多个接收器光学采集指纹数据。壳体组件110具有1个或多个指纹识别区111和一光线传输通道112，指纹识别区111靠近光线传输通道112。指纹识别组件位于壳体组件110内，指纹识别组件靠近光线传输通道112，指纹识别组件发出的光线适于从光线传输通道112传递、经所述指纹识别区111反射后返回至指纹识别组件。
需要说明的是，指纹识别组件可以发出的光线，例如，指纹识别组件可以为利用红外光线识别指纹图形的指纹识别传感器，当手指覆盖指纹识别区111时，光线101照射到指纹识别区111，并被反射到光线传输通道112内，光线101再被指纹识别组件接收，指纹识别组件可以根据接收到的光线信息采集指纹信息。
根据本申请实施例的电子设备100，通过在壳体组件110内设置光线传输通道112可以利用光线的可传递性，将承载有指纹信息的光信号传递给指纹识别组件，以识别指纹信息，由此可以将指纹识别组件隐藏在壳体组件110内，避免将指纹识别组件设置在壳体组件110的外表面上，从而可以减少设置在壳体组件110外表面的部件，提升电子设备100的完整性。
根据本申请的一些实施例，电子设备100包括显示屏130，显示屏130可以用于向用户显示图像或文字信息，显示屏130位于壳体组件110内。壳体组件110包括盖板121，盖板121与显示屏130层叠设置，盖板121和显示屏130之间具有间隙131，间隙131构造成光线传输通道112，指纹识别区111设于盖板121。
可以理解的是，可以利用盖板121与显示屏130之间的间隙131构造成光线传输通道112，即可以充分利用电子设备100的现有部件，构造出指纹识别组件所需要的光线传输通道112，由此，不但可以减少电子设备100的部件数量，还可以节省壳体组件110的内部空间，便于优化电子设备100的内部空间。
在一些实施例中，如图1所示，盖板121的至少部分边缘超出显示屏130的边缘，盖板121的超出显示屏130的部分为反射部122，指纹识别组件与反射部122相对，光线传输通道112内的光线适于经反射部122反射后在光线传输通道112和指纹识别组件之间传递。由此可以利用反射部122、并结合光线反射特性，改变光线传输通道112的延伸方向，从而可以根据电子设备100的内部结构灵活放置指纹识别组件的位置。
图1所示，根据本申请的一些实施例，盖板121的超出显示屏130的部分弯折以构造成所述反射部122。可以理解的是，通过在盖板121上设置弯折的部分，并利用弯折的部分构造出反射部122，由反射部122构造出的光线传输通道112可以形成一个转弯，光线在光线传输通道112内反射时，转弯结构更容易使光线产生反射，从而可以提升光线的发射率， 进而可以使指纹识别组件采集到更多的指纹信息，提升指纹识别组件的识别效率和精度。
为了提升反射部122的反射效率，在本申请的一些实施例中，反射部122具有第一涂层123。进一步地，第一涂层123可以为铝层。更进一步地，第一涂层123的表面粗糙度为Ra≤10微米。在本申请的一些实施例中，盖板121可以为玻璃盖板121、蓝宝石盖板121。在一些实施例中，盖板121的红外光线的透过率可以大于等于80％。在一些实施例中，盖板121的厚度可以大于等于0.8mm，由此可以提升光线的穿过量，从而可以为指纹识别组件提供更多的指纹图像信息，进而可以提升指纹识别组件的指纹识别的准确率。在本申请的一些实施例中，显示屏130可以为OLED屏或LCD屏。
为了提升光线传输通道112的光线传输效率，根据本申请的一些实施例，光线传输通道112的至少部分内周壁设有第二涂层113。进一步地，第二涂层113可以为油墨层。需要说明的是，油墨内掺杂的扩散粒子少，可以提升光线的折射效率。
如图1所示，根据本申请的一些实施例，指纹识别组件可以包括信号发射件150和信号接收件160，其中，信号发射件150发射的光线适于进入光线传输通道112，且光线经过指纹识别区111后被信号接收件160接收。需要说明的是，信号发射件150和信号接收件160可以分开设置，例如信号发射件150和信号接收件160可以位于壳体组件110内部的不同位置，从而可以灵活设置指纹识别组件，占用较小的壳体组件110的内部空间，降低整体式指纹识别组件对容纳空间的要求，进而可以优化壳体组件110的部件的布局。
根据本申请的一些实施例，信号发射件150可以为主动式光源模组。需要说明的是，主动式光源模组可以提供近准直红外波段光源，而且主动式光源模组可弹性的选择指纹发光的时机，并不受限于屏幕亮度。进一步地，通过选用主动式光源模组，在设计电子设备100的外表面时，无需修改面板的设计，且不影响显示面的色域、饱和度、解析度及亮度。
根据本申请的一些实施例，指纹识别组件可以为多个。由此可以灵活选择指纹识别组建的个数、设计指纹识别组件的排布方式，从而可以提升电子设备100的多样性。
根据本申请的一些实施例，光线传输通道112内具有光纤。需要说明的是，光纤的内部介质可以构造成光线传输通道112，即光纤作为光线传输的载体，由此可以使光线在光纤内部迅速、高效地传输，降低光线的损失率。当然，光线传输通道112的形式并不限于此，例如，在本申请的一些实施例中，光线传输通道112内设有具有导光层，导光层可以为有具有导光性能的材料制成的结构，其可以形成为柱状，也可以形成为片状。
根据本申请的一些实施例，如图1所示，指纹识别区111可以为多个，由此可以提升指纹识别区111的设置灵活度，可以在壳体组件110的外表面上多点的位置进行选择。
根据本申请的一些实施例，如图2所示，电子设备100包括显示屏130，壳体组件110包括前壳114和后壳115，显示屏130嵌设于前壳114，后壳115与前壳114连接，光线传 输通道112位于显示屏130和后壳之间，指纹识别区111位于后壳115。由此可以在电子设备100的后壳上实现指纹识别。
如图1、图2所示，根据本申请实施例的电子设备100，包括外观件、显示屏130和指纹识别组件。
具体而言，外观件具有指纹识别区111，显示屏130与外观件层叠设置，显示屏130与外观件之间构造出光线传输通道112，光线传输通道112的部分侧壁由指纹识别区111构造出，指纹识别组件包括信号发射件150和信号接收件160，信号发射件150位于光线传输通道112的一端，信号接收件160位于光线传输通道112的另一端，信号发射件150发射的光线适于进入光线传输通道112，且光线经过指纹识别区111反射后被信号接收件160接收。
根据本申请实施例的电子设备100，通过利用外观件和显示屏130限定出光线传输通道112，且利用外观件的指纹识别区111构造出光线传输通道112的部分侧壁，以供指纹识别组件识别指纹信息，由此可以将指纹识别组件隐藏在电子设备100内，减少设置在电子设备外表面的部件，提升电子设备的完整性。
根据本申请的一些实施例，外观件可以为保护显示屏130的盖板，或者外观件为电子设备100的后壳。

信号发射件150和信号接收件160可以分开设置，例如信号发射件150和信号接收件160可以位于壳体组件110内部的不同位置，从而可以灵活设置指纹识别组件，占用较小的壳体组件110的内部空间，降低整体式指纹识别组件对容纳空间的要求，进而可以优化壳体组件110的部件的布局。
信号发射件150可以为主动式光源模组。需要说明的是，主动式光源模组可以提供近准直红外波段光源，而且主动式光源模组可弹性的选择指纹发光的时机，并不受限于屏幕亮度。进一步地，通过选用主动式光源模组，在设计电子设备100的外表面时，无需修改面板的设计，且不影响显示面的色域、饱和度、解析度及亮度。
