本申请实施例涉及的移动终端100可以是任何具备通信和存储功能的设备，例如：平板电脑、手机、电子阅读器、遥控器、个人计算机(Personal Computer，PC)、笔记本电脑、车载设备、网络电视、可穿戴设备等具有网络功能的智能设备。
请参照图1和图2，本申请第一实施例提供的一种移动终端100，移动终端100包括显示装置1，显示装置1包括显示屏11、指纹识别模组12和间隔件13，所述显示屏11具有相对设置的显示面111和背面112，所述显示面111具有用于显示图像的显示区域111a，所述间隔件13设置于所述显示屏11的背面112上，且所述间隔件13用以使所述指纹识别模组12与所述显示屏11的背面112相隔设置，所述指纹识别模组12用于识别在所述显示区域111a内所输入的指纹信息。
可以理解的，若将指纹识别模组12直接安装在显示屏11的背面112上，由于指纹识别模组12中的芯片存在，需要较高的温度将指纹识别模组12热压于显示屏11上，热压的工艺可能会损坏显示屏11，并且导致显示屏11与指纹识别模组12安装后，两者之间的连接处存在褶皱，影响两者之间的平行。当显示屏11为柔性屏比如OLED(Organic Light-Emitting Diode，有机激光显示)屏时，该问题愈加突显。由于柔性屏较软，指纹识别模组12与柔性屏的安装，更容易导致柔性屏与指纹识别模组12的连接处产生褶皱，使得柔性屏与指纹识别模组12之间存在较大的夹角，若指纹识别模组12为需要柔性屏与指纹识别模组12具有较小夹角才能够保证指纹识别模组12的准确采集的器件如光学指纹识别器件，则导致指纹识别的精度较低。因此采用间隔件13使指纹识别模组12与显示屏11的背面112相隔设置即指纹识别模组12既能够固定于移动终端100的内部来识 别在显示区域111a内所输入的指纹信息，还能够不与显示屏11直接接触，保证指纹识别模组12与显示屏11的平行，来提高指纹识别的精度。
可以理解的，本实施例中的显示屏11主要以能够进行柔性弯折的柔性屏来进行应用讲解。当然，在其它实施例中，显示屏11还可以为硬屏如液晶显示屏11。
本实施例中，请参照图1和图2，显示屏11定义为能够进行图像的显示和触摸来进行指令的输入，即显示屏11具有显示功能和触摸功能。显示屏11的显示面111具有用于显示图像的显示区域111a和非显示区域111b，而由于显示区域111a亦能够进行指纹信息的输入，故非显示区域111b于显示面111上的占比较低，反之，显示区域111a于显示面111上的占比极大的提高。当然，在其它实施例中，显示屏11可以只具有显示功能。
可以理解的，请参照图2，指纹识别模组12为光学指纹识别器件，光学指纹识别器件能够经显示屏11向外界发射感应光线，并接受从显示屏11上输入的指纹触摸而对应反射回来的感应光线，反应回来的感应光线即指纹信息。其中，指纹识别模组12在显示区域111a上的正投影区域即用户能够输入指纹信息的区域，此处将该区域定义为指纹输入区域111c。用户可以通过在指纹输入区域111c按压指纹来供指纹识别模组12识别，以对移动终端100进行控制，比如解锁。当然，在其它实施例中，指纹识别模组12还可以为超声波指纹识别器件，超声波指纹识别器件通过发射和接受超声波来进行指纹的收集和识别。
为了更进一步的改进，请参照图2，所述指纹识别模组12与所述显示屏11的背面112之间的间距d1大于或等于0.1mm。具体的，指纹识别模组12与显示屏11的背面112之间的间距d1为0.2mm，申请人经过大量的实验研究发现，指纹识别模组12与显示屏11的背面112之间的间距d1控制在0.2mm之间在使指纹识别模组12不直接连接在显示屏11上的同时，还能够更好的保证指纹识别模组12对显示区域111a所输入的指纹信息的采集。当然，在其它实施例中，指纹识别模组12与显示屏11之间的间距d1还可以为0.1mm、0.3mm等等。
在本实施例中，请参照图2，所述间隔件13设置于所述显示屏11的背面112上，且所述间隔件13用以使所述指纹识别模组12与所述显示屏11的背面112相隔设置。具体的，所述间隔件13包括相背设置的第一端面13a和第二端面13b，此处将间隔件13朝向显示屏11的背面112的一端面定义为第一端面13a，将间隔 件13朝向指纹识别模组12的一端面定义为第二端面13b。其中，所述第一端面13a固定于所述显示屏11的背面112上，所述第二端面13b设置有所述指纹识别模组12，即间隔件13的高度与指纹识别模组12与显示屏11的背面112之间的间距d1对应，间隔件13多高，指纹识别模组12与显示屏11的背面112之间的间距d1则多大。
可以理解的，所述间隔件13与所述背面112连接的端面与所述间隔件13与所述指纹识别模组12连接的端面之间形成小于5°的夹角。即第一端面13a与第二端面13b之间形成小于5°的夹角。具体的，第一端面13a与第二端面13b之间的夹角为0°，即第一端面13a平行于第二端面13b，从而保证指纹信息的准确采集和识别。
一种实施例中，请参照图3，所述间隔件13包括透明的隔板131，所述间隔件13设置于所述显示屏11的背面112和所述指纹识别模组12之间，通过透明的隔板131设置于显示屏11的背面112和指纹识别模组12之间，使得指纹识别模组12不与显示屏11直接接触，保证指纹识别模组12与显示屏11的平行，提高指纹识别模组12的指纹识别的精度。
具体的，隔板131为矩形的薄板，隔板131具有一定强度，隔板131的厚度可以为0.2mm，即隔板131将显示屏11的背面112与指纹识别模组12隔开0.2mm。透明的隔板131保证指纹识别模组12能够将感应光线依次经隔板131、显示屏11发射出去，并且反射回来感应光线能够依次经显示屏11、隔板131到指纹识别模组12上。
隔板131的第一端面13a通过低温热压于显示屏11的背面112上，指纹识别模组12通过高温热压于间隔件13的第二端面13b上，由于隔板131具有一定的硬度，故显示屏11在柔性弯折时，对应设置有隔板131的部位不会产生弯折而导致褶皱的产生，并且指纹识别模组12高温设置于间隔件13上不会使得隔板131产生褶皱，因此只需要保证隔板131的第一端面13a和第二端面13b平行设置，即可保证指纹识别模组12与显示屏11的背面112的平行，从而保证指纹信息的准确采集和识别。当然，在其它实施例中，指纹识别模组12还可以利用移动终端100内部的各个器件的位置关系直接抵接于隔板131的第二端面13b上。
进一步的，请参照图3，所述间隔件13还包括多个凸点132，所述多个凸点132设置于所述隔板131朝向所述显示屏11的背面112的一端面(第一端面13a) 上上，和/或；所述多个凸点132设置于所述隔板131朝向所述指纹识别模组12的一端面(第二端面13b)上。
通过在隔板131上设置多个凸点132，减少隔板131分别与显示屏11的背面112和/或指纹识别模组12的接触面积，进一步保证显示屏11的背面112与指纹识别模组12之间的平行，进一步提高指纹识别模组12的识别精度。
具体的，凸点132为柱形凸点，多个凸点132分别设置于隔板131的第一端面13a和隔板131的第二端面13b上，如此隔板131与显示屏11的背面112和指纹识别模组12的接触面积大大的较少，则显示屏11日常使用时需要弯折时，显示屏11的背面112与隔板131的连接处之间亦不会产生较大的褶皱，影响指纹信息的采集。
可以理解的，请参照图4，多个凸点132还可以只设置于隔板131的第一端面13a；请参照图5，多个凸点132还可以只设置于隔板131的第二端面13b。
另一种实施例中，请参照图6，所述间隔件13包括多个透明的间隔柱133，所述多个间隔柱133设置于所述显示屏11的背面112和所述指纹识别模组12之间，所述多个间隔柱133均匀间隔排列。
具体的，间隔柱133为圆柱形的柱体，每个间隔柱133的直径为0.1mm，间隔柱133的高度为0.2mm。间隔柱133与显示屏11的背面112靠近的一面为第一端面13a，间隔柱133与指纹识别模组12靠近的一面为第二端面13b，间隔柱133的第一端面13a通过低温热压于显示屏11的背面112上，指纹识别模组12通过高温热压于间隔柱133的第二端面13b上。通过将间隔件13设置为多个透明的间隔柱133，使得间隔件13与显示屏11和指纹识别模组12接触为点面接触，多个间隔柱133与显示屏11的背面112和指纹识别模组12的接触面积较小，则显示屏11日常使用时需要弯折时，显示屏11的背面112与间隔柱133的连接处之间亦不会产生较大的褶皱，影响指纹信息的采集。
当移动终端100开始装配时，将间隔件13(上述两个间隔件13的结构皆可)的第一端面13a对应热压于显示屏11的背面112上，指纹识别模组12固定于间隔件13的第二端面13b上，如此由于间隔件13具有一定的硬度，故显示屏11在柔性弯折时，对应设置有间隔件13的部位不会产生弯折而导致褶皱的产生，并且指纹识别模组12高温设置于间隔件13上不会使得间隔件13产生褶皱，因此只需要保证间隔件13的第一端面13a和第二端面13b平行设置，即可保证指纹识别模 组12与显示屏11的背面112的平行，从而保证指纹信息的准确采集和识别。用户使用该移动终端100时，只需要在对应的指纹输入区域111c输入指纹，既可实现指纹的识别，并且移动终端100弯折时，设置有间隔件13的显示屏11对应部位不会进行弯折，保证了指纹识别模组12与显示屏11的平行，从而保证了指纹识别模组12的识别精度。
本申请提供的显示装置1和移动终端100通过将指纹识别模组12设置在显示屏11的背面112，使得用户既可通过显示屏11的显示区域111a输入指纹信息，又提高了移动终端100的屏占比，并且通过间隔件13使指纹识别模组12与显示屏11的背面112相隔设置，使得指纹识别模组12不直接与显示屏11接触，避免指纹识别模组12与显示屏11之间的接触影响指纹识别的精度，即提高了指纹识别的精度。
请参照图7，为申请第二实施例提供的一种移动终端200，该移动终端200与第一实施例的移动终端100基本相同，其不同之处在于间隔件23朝向指纹识别模组12的一端面(此处将该端面定义为第二端面23b)开设凹槽23c，所述指纹识别模组22容置于所述间隔件23的凹槽23c中。
具体的，间隔件23为一矩形块，间隔件23的凹槽23c与指纹识别模组22的尺寸大致相同，凹槽23c的底面23d与间隔件23朝向显示屏11的背面112的一端面(此处将该端面定义为第一端面23a)平行设置，使得指纹识别模组22容置于凹槽23c中时，指纹识别模组22仍与显示屏21的背面212平行，保证较佳的指纹识别精度。而间隔件23的第一端面23a至凹槽23c的底面23d的距离即指纹识别模组22与显示屏21的背面212的间距d2。该间隔件23将指纹识别模组23收容于自身的凹槽23c中，节省了移动终端200内部的空间，进一步优化了移动终端200的结构。
可以理解的，本申请第一实施例所列举的间隔件13与显示屏11的背面112的连接方式、连接结构与方式同样能够使用本申请第二实施例，在此不做赘述。
以上是本申请的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也视为本申请的保护范围。
