具体实施方式
下面将结合本申请实施方式中的附图，对本申请实施方式中的技术方案进行清楚、完整地描述。
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至图4，本申请提供的一种移动终端100，该移动终端100包括显示装置10。显示装置10包括显示屏1、指纹识别模组2和感应件3，指纹识别模组2设置于显示屏1上，指纹识别模组2具有指纹接触面21a，显示屏1的像素结构11具有多个用于显示屏1显示的像素单元111和多个用于照射待识别指纹20识别用光的备用像素112，相邻两个像素单元111之间设置有间隙，多个备用像素112分别位于多个间隙中，感应件3电连接于显示屏1，以使得备用像素112在待识别指纹20接近指纹接触面21a时发光。
通过在显示屏1的像素结构11上增设多个备用像素112并通过感应件3感应待识别指纹20的接触启动备用像素112来作为识别指纹用光，使得指纹识别模组2工作时所需的光源无需使用像素单元111的光，影响显示屏1的寿命。
本实施例中，请参照图3，显示屏1为OLED(Organic Light-Emitting Diode, 有机发光二极管)屏，其具有较薄的厚度和较佳的挠性，利于移动终端100的轻薄。显示屏1具有相背设置的正面1a和背面1b，正面1a具有用于显示图像的 显示区域D1和非显示图像的非显示区域D2。当然，在其他实施例中，显示屏1还可以LED(Light-Emitting Diode，发光二极管)屏。
其中，请参照图2，显示屏1的多个像素单元111阵列排布，且各个像素单元111之间设置有间距，以便于规律且均匀的为显示屏1上的各个位置提供显示图像所需的光。可以理解的，像素单元111包括红像素点、绿像素点和蓝像素点。上述三种像素点的颜色组合能够为显示屏1形成较佳的色度，便于人眼观看显示屏1。
请参照图2，多个备用像素112分别位于多个间隙中，以不干扰像素单元111的发光，影响显示屏1的显示。可以理解的，备用像素112为绿色像素点。绿色光源能够进一步保护用户的眼睛，进一步提高了移动终端100的可靠性。当然，在其它实施例中，备用像素112还可以为红色像素点或蓝色像素点等。
本实施例中，请参照图3，指纹识别模组2设置于显示屏1上，使得移动终端100具有指纹识别的功能。具体的，指纹识别模组2靠近显示屏1的一面为指纹接触面21a，以便于用户在显示屏1进行指纹按压。
可以理解的，指纹识别模组2包括封装在一起的棱镜21、图像传感器22和指纹控制器23，棱镜21靠近显示屏1设置，且棱镜21靠近显示屏1的一面为指纹接触面21a，备用像素112发出的光线照射至压有待识别指纹20的指纹接触面21a上并与待识别指纹20发生全反射，全反射的光线经棱镜21入射至图像传感器22，图像传感器22根据全反射的光线获取指纹图像，指纹控制器23识别图像传感器22发送的指纹图像。
具体的，指纹识别模组2中的棱镜21、图像传感器22和指纹控制器23由于封装在一起，故指纹识别模组2整体呈块状。棱镜21、图像传感器22和指纹控制器23通过EMC(环氧塑封料)塑料封装在一起。其中，指纹识别模组2的封装工艺不会影响棱镜21等光学器件的正常工作。
用户可以通过将指纹按压于棱镜21的指纹接触面21a上来进行指纹识别。图像传感器22和指纹控制器23位于棱镜21的下方，即图像传感器22和指纹控制器23远离指纹识别模组的指纹接触面21a，以便于图像传感器22获取反射至棱镜21上的光线，从而将光信号转换为电信号传递给指纹控制器23进行处理。
本实施例中，请参照图3，感应件3电连接于显示屏1，以使得备用像素112在待识别指纹20接近指纹接触面21a时发光。可以理解的，感应件3为接近传感 器。接近传感器靠近棱镜21设置，并与显示屏1电连接，当用户将待识别指纹20按压于显示屏1之正对指纹接触面21a上或直接按压于指纹接触面21a上时，感应件3感知信号，显示屏1的多个备用像素112发射光线与待识别指纹20发生全反射，全反射的光线经棱镜21入射至图像传感器22，图像传感器22根据全反射的光线获取指纹图像，指纹控制器23识别图像传感器22发送的指纹图像。并且，在用户的待识别指纹20离开后，感应件3感应不到信号，显示屏1的多个备用像素112停止发光。通过在显示屏1的显示结构上增设多个备用像素112并通过感应件3感应待识别指纹20的接触启动备用像素112来作为识别指纹用光，使得指纹识别模组2工作时所需的光源无需使用像素单元111的光，影响显示屏1的寿命。当然，在其它实施例中，感应件3还可以为距离传感器或压电传感器等。
为了更进一步的改进，请参照图3，指纹识别模组2设置于背面1b，指纹识别模组2于显示屏1上的正投影区域位于显示区域D1的内部。具体的，封装的整个指纹识别模组2通过高温热压于显示屏1的背面1b上。其中，棱镜21的指纹接触面21a热压于显示屏1的背面1b上。可以理解的，由于指纹识别模组2为光学指纹识别器件，故显示屏1的背面1b上对应设置有该指纹识别模组2的位置去除遮光材料，便于光线射入棱镜21中。当然，在其它实施例中，请参照图4，显示屏1设置中空槽2a，指纹识别模组2容置于显示屏1的中空槽2a内。
可以理解的，进行指纹识别操作时，只需要在指纹识别模组2于显示屏1上的正投影区域按压待识别指纹20，即可进行指纹识别操作。为了便于叙述，将该正投影区域定义为指纹识别区域D3。通过将指纹识别模组2设置于显示屏1的背面1b，即将指纹识别模组2容置于移动终端100的内部，并且指纹识别模组2还位于显示屏1的显示区域D1内，从而使得在指纹识别模组2不进行指纹识别时，指纹识别区域D3还可以进行显示，提高了显示装置10的屏占比。
为了更进一步的改进，请参照图2，多个备用像素112集中于指纹识别模组2在显示屏1的正投影区域即指纹识别区域D3内。本实施例中，多个备用像素112均匀间隔排列于指纹识别区域D3内，保证进行指纹识别操作时具有较佳的光线能够进行指纹识别，从而提高指纹识别的精度。具体的，多个备用像素112排列而成的形状与指纹接触面21a的形状相同。当然，在其它实施例中，多个备用像素112还可以均匀排布于显示屏1的各个位置。该移动终端100使用时， 需要将指纹识别组件热压于显示屏1的背面1b，感应件3靠近指纹识别组件设置于移动终端100的内部。用户将待识别指纹20按压于显示屏1之正对指纹接触面21a上或直接按压于指纹接触面21a上时，感应件3感知信号，显示屏1的多个备用像素112发射光线与待识别指纹20发生全反射，全反射的光线经棱镜21入射至图像传感器22，图像传感器22根据全反射的光线获取指纹图像，指纹控制器23识别图像传感器22发送的指纹图像；并且，在用户的待识别指纹20离开后，感应件3感应不到信号，显示屏1的多个备用像素112停止发光。
本申请提供的显示装置10和移动终端100通过在显示屏1的显示结构上增设多个备用像素112并通过感应件3感应待识别指纹20的接触启动备用像素112来作为识别指纹用光，使得指纹识别模组2工作时所需的光源无需使用像素单元111的光，影响显示屏1的寿命。
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。
