在本实施例中，所述LED装置发出的光线经过内部反光膜的反射最终汇合到油墨层2的开口位置射出，光线通过所述油墨层2的底色和所述开口可以形成预先设定的光亮形状或图案，在黑暗的环境中用以引导用户的操作，提升用户的使用体验。
实施例二
在第一实施例的基础上，参阅图2所示，为本申请所述传感器装置第二实施例的结构示意图，所述传感器装置还包括接收模块8，用于接收发光模块4发出的，经用户手指反射回的光线。在所述发光模块4和所述接收模块8的中间设置有隔光层9，所述隔光层9位于油墨层2和传感器5之间，且油墨层2、隔光层9和传感器5三者间无间隙，所述隔光层9由不透光的材质制成，用于隔离光线，防止所述发光模块4发出的光直接被所述接收模块8接收。
通过分析用户手指反射回的光线，可以实现心率检测等功能。此外，在传感器5是指纹传感器的情况下，利用接收模块8接收的反射光线，还可以实现用户的活体检测，杜绝使用伪造指纹通过检测的可能，提高指纹识别的安全性。
本实施例中，传感器5，发光模块4以及接受模块8合并封装在一起，所述传感器5的上表面覆盖有下反光膜6，所述下反光膜6在所述发光模块4顶端、接收模块8顶端对应的位置开口，所述开口形状与所述发光模块4顶端、接收模块8顶端与传感器接触面的形状一致。在其他实施例中，传感器5也可以单独封装，发光模块4和接收模块8为独立于传感器封装的结构。
在本实施例中，加入了接收模块8，接收用户手指反射回的光线，在提供发光引导的同时还可以实现活体检测、心率检测等功能。
实施例三
在前两个实施例的基础上，参阅图3所示，为本申请所述传感器装置第三实施例的结构示意图，所述传感器装置还包括套环10、柔性电路板11以及补强板12。
所述套环10设置于所述传感器装置的***，并将所述盖板1以及所述传感器装置内其他组件包裹在内，在本实施例中，所述套环10是金属环，但不限于金属环，在其他实施方式中，也可以是其他材质；所述套环10在所述盖板1正面上形成的形状包括矩形、圆形等。
所述传感器装置并排设置在柔性电路板(FPC)11的上方，所述柔性电路板11的下方还可以固定设置补强板12，用以提升所述柔性电路板11的韧性强度。
传感器装置的具体结构可参阅前两个实施例，本实施例中不再赘述。
实施例四
在前述实施例中公开的传感器装置的基础上，本实施例公开一种移动终端，包括前述实施例公开的传感器装置，以在移动终端上实现用户指纹检测、心率检测，以及活体检测等功能。
本实施例中的移动终端包括但不限于智能手机、笔记本电脑、平板电脑等。
上述实施例为本申请较佳的实施方式，但本申请的实施方式并不受上述实施例的限制，其他的任何未背离本申请的精神实质与原理下所作的改变、修饰、替代、组合、简化，均应为等效的置换方式，都包含在本申请的保护范围之内。
