所述光学指纹感应器12，用于获取用户输入的指纹图案；
所述补光灯13，还用于在所述光学指纹感应器12获取输入的指纹图案的情况下，对所述指纹图案进行补光。
采用本公开实施例的补光灯模组进行指纹识别，能够提高补光灯的利用率，也无需提高生产成本，且补光灯模组结构简单，能够有效节约空间，利于终端设备的轻薄化设计，使得终端设备更为美观。
上述实施例中，所述电路板11可以为单独的电路板，与所述终端设备的主板连接；也可以为所述终端设备的主板，利于终端设备的轻薄化设计，本公开不作限定。
上述实施例中，所述电路板11可以为印制电路板(Printed Circuit Board， PCB)，也可以为柔性电路板(Flexible Printed Circuit，FPC)，本公开不作限定。
可选地，可使用表面组装技术(Surface Mount Technology，SMT)焊接工艺，或者，贴片(Die bonding)工艺和打线(Wire Bonding)工艺将所述光学指纹感应器12封装于所述电路板11上。
由于高屏占比的终端设备受到越来越多的用户的欢迎，因此，可选地，所述补光灯模组为后置补光灯模组。即，所述补光灯13为所述终端设备的后摄像头的闪光灯。从而，能够有效地节省空间，利于生产出更高屏占比的终端设备，给用户带来更好的视觉体验。
当然，所述补光灯模组也可以为前置补光灯模组，使得用户进行指纹识别时，操作简单，更加方便便捷。
可选地，所述补光灯为环形灯带，所述光学指纹感应器位于所述环形灯带内。
例如：参阅图2，所述补光灯13为发光二极管1301组成的环形灯带131，所述光学指纹感应器12位于所述环形灯带131的中央。
其中，所述补光灯13可以为多个发光二极管1301组成的环形灯带131，例如：8个发光二极管1301，可以根据实际情况，调整发光的发光二极管1301的数量、发光二极管1301发出的光线的颜色和色温，使得补光灯13发出合适亮度、颜色的光线，获取更清晰的指纹图案。
可选地，所述补光灯模组还包括控制器，与所述光学指纹感应器和所述补光灯连接，用于控制所述补光灯点亮和所述光学指纹感应器启动。
其中，所述控制器可以为单独的控制器，反应更为迅速。
当然，也可以由终端设备的处理器控制所述补光灯点亮和所述光学指纹感应器启动，更为节约空间。
可通过多种方式判断是否需要进行指纹识别，例如：可以通过检测压力值或电容值是否发生变化，来检测是否有手指按压，又如：可通过检测是否有用于进行指纹识别的语音信息(如：语音内容为“开启指纹识别”的语音信息)，来检测是否有手指按压。当检测到手指按压或用于进行指纹识别的语音信息时，判定需要进行指纹识别，控制补光灯点亮和光学指纹感应器启动。
参阅图3-4，图3是本公开实施例二的终端设备的示意图，图4是本公开实施例二的终端设备延中轴线的剖面示意图，该终端设备30具有摄像模组(图未示)，包括补光灯模组32，补光灯模组32为上述实施例中的补光灯模组，终端设备30上设置有指纹识别透光区域311，补光灯模组32对应所述指纹识别透光区域311设置。
采用本公开实施例的终端设备，通过光学指纹技术进行指纹识别，能够提高补光灯的利用率，也无需提高生产成本，且补光灯模组结构简单，能够有效地节约空间，利于终端设备的轻薄化设计，使得终端设备更为美观。
可选地，请继续参阅图3-4，所述补光灯模组32为后置补光灯模组，所述终端设备30还包括后盖31，所述后盖31上设置有所述指纹识别透光区域311。
下面，对本公开实施例的终端设备采集手指指纹的过程进行简要说明。
请参阅图5，图5是终端设备获取指纹图案的工作原理示意图。手指放置在指纹识别透光区域311，补光灯322发射的光线穿过指纹识别透光区域311，经手指51反射后，再次穿过指纹识别透光区域311，进入光学指纹感应器321，光学指纹感应器321检测到手指51的指纹反射的补光灯322的光线，根据检测结果生成指纹图案，从而获取到用户输入的指纹图案，完成手指指纹的采集。
在本公开的一些可选的实施例中，所述后盖31可以采用透明材料(如：玻璃、透明树脂等)制成，如图5所示。从而，无需在后盖开孔，也不会破坏后盖外观的一体性，终端设备的整体外观效果也更为美观，且进一步降低了加工难度和生产成本。
请参阅图6，当然，在本公开的另一些可选的实施例中，所述后盖31也可以采用不透明材料制成，所述后盖31上开设有开孔312，所述开孔312对应所述指纹识别透光区域311。
此时，光学指纹识别模组可以被设计为正好嵌入所述开孔312中，且光学指纹感应器321和补光灯322均覆盖有由透明材料制成的保护膜，能更快速地检测到手指按压，灵敏度更高，且能节约制作材料，进一步降低生产成本，也有利于终端设备的轻薄化设计，使得终端设备更为美观。
可选地，所述终端设备30还包括：透明盖板313，其设置在所述开孔312上，请参阅图7。从而，能够对补光灯模组起到保护作用，延长补光灯模组的寿命。
在本公开的一些可选的实施例中，所述终端设备还包括：
处理器，与所述光学指纹感应器连接，用于将所述光学指纹感应器获取的指纹图案与预存指纹图案进行比对，当比对出所述指纹图案与所述预存指纹图案匹配时，生成用于表示识别成功的第一信息，当比对出所述指纹图案与所述预存指纹图案不匹配时，生成用于表示识别失败的第二信息。
具体地，处理器可以将光学指纹感应器获取的指纹图案转换成数字信号，将数字信号与预存指纹图案进行比对，可根据比对结果执行不同的操作，例如：当比对出所述指纹图案与所述预存指纹图案匹配时，执行对应操作(如：解锁、支付或应用登录等)；当比对出所述指纹图案与所述预存指纹图案不匹配时，在终端设备的显示屏上显示“验证失败”的文字信息。
可选地，所述处理器，还用于根据所述终端设备周围环境的光线的强度和/或手指的信息，控制发光的发光二极管的数量和/或发光二极管发出的光线的颜色。
其中，所述手指的信息可以为以下至少之一：指纹的沟和脊的清晰度、手指的干燥度和手指的清洁度。从而，不仅能获取更清楚的指纹图案，还有利于节约能耗。
通过调整发光的发光二极管的数量(例如：控制部分或全部发光二极管点亮)、发光二极管发出的光线的颜色和色温，能够使得补光灯发出合适亮度、颜色的光线，获取更清晰的指纹图案。例如：可以按照从少到多的顺序控制发光二极管点亮，当发出的光线的亮度最优时，保持当前数量个发光二极管的点亮状态，进行指纹的采集。
在本公开的一些可选的实施例中，为保证手指放置的准确性，可采用CNC加工(精密加工)或蚀刻等工艺，对指纹识别透光区域和/或其周围进行加工，以使用户能感受到特殊的物理结构，从而引导用户迅速、准确地放置手指，提升获取的指纹的完整性。
在相关技术中，为了生产高屏占比的终端设备，往往会采用屏下光学指 纹识别方案。然而，要实现屏下光学指纹识别，只能在有机发光二极管(Organic Light-Emitting Diode，OLED)显示屏上进行屏下光学指纹识别，而仅有韩系、日系等几家供应商供应OLED显示屏，选择的局限性较大。而且，为实现光学屏下指纹识别，在显示屏背面对应光学指纹位置的遮蔽材料层上，需要进行开孔，会对显示屏的显示效果和外观效果产生负面影响。另外，OLED显示屏本身价格较高，还需要贴合显示屏与光学指纹识别组件，拉长了显示屏的加工制程，且显示屏与光学指纹识别组件贴合后，返修难度较大，会降低显示屏的整体良率，增加生产成本。
而采用本公开实施例的技术方案，不仅能提高补光灯的利用率，而且，对终端设备的显示屏不会产生任何影响，无需将显示屏与补光灯组件进行贴合，生产工艺简单，能够降低终端设备的生产成本，且能避免对显示屏结构的完整性造成破坏，降低因贴合而导致的显示屏的不良率。
