图4为本公开实施例提供的识别方法的流程图。
具体实施方式
下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
为了更好的理解本公开，首先对本公开涉及的指纹识别技术的基本原理进行简要介绍：如图1所示，显示面板包括保护玻璃盖板101和OLED屏单元102，OLED屏单元102上设置有发射光源103，当手指按压在显示面板的保护玻璃盖板101上时，发射光源103发出的光线经过手指反射，穿过显示面板的保护玻璃盖板101和OLED屏单元102被内部的指纹识别模组104接 收从而实现指纹识别功能。但要想实现双屏幕均具有指纹识别功能，需要设置两个独立的指纹识别模组，大大增加了成本和占用空间。
在本公开的一些实施例中，参照图2所示，提供了一种移动终端，包括：
第一显示面板21，所述第一显示面板21为透光件；
第二显示面板22，所述第二显示面板22与所述第一显示面板21相背设置，所述第二显示面板22为透光件；
识别模组23，所述识别模组23设置在所述第一显示面板21和所述第二显示面板22之间；
光调节件24，所述光调节件24设置在所述第一显示面板21和所述第二显示面板22之间，所述光调节件24将从所述第一显示面板21和所述第二显示面板22进入的光线反射至所述识别模组23。
这里，第一显示面板21和第二显示面板22均采用透光材质，如此第一显示面板21和第二显示面板22均能够透过光线以实现生物识别信息的识别功能。其中，检测到生物识别信息输入时，可控制生物识别信息输入所施加的目标显示面板发射光线，目标显示面板为第一显示面板21和第二显示面板22中的其中一个，使得目标显示面板发射的光线经过生物体遮挡反射进目标显示面板，光调节件24将从目标显示面板进入的光线反射至识别模组23，识别模组23利用光调节件24反射的光线对当前的生物识别信息输入进行识别。从而利用一个识别模组实现两个显示面板上的生物识别信息的识别功能，降低了成本，且节约了占用的空间。
其中，识别模组23如可为指纹识别模组、人脸识别模组、瞳孔识别模组等，但不限于此。以指纹识别模组为例，当手指按压在第一显示面板21或第二显示面板22上，检测到指纹信息输入时，可控制指纹信息输入所施加的目标显示面板发射光线，目标显示面板发射的光线经过手指遮挡反射进目标显示面板，光调节件24将从目标显示面板进入的光线反射进指纹识别模组，指纹识别模组利用光调节件24反射的光线能够对当前的指纹信息输入进行指纹识别。从而利用一个识别模组实现两个显示面板上的指纹识别功能，降低了成本，且节约了占用的空间。
其中，第一显示面板21和第二显示面板22均可采用OLED(Organic  Light-Emitting Diode，有机发光二极管)显示面板，但不限于此。
其中，可利用第一显示面板21和第二显示面板22自身的发光单元作为发射光源，也可利用单独设置的发光单元作为发射光源。例如，第一显示面板21和第二显示面板22均采用OLED显示面板时，可利用OLED显示面板像素自发光单元作为发射光源，当检测到生物识别信息输入时，控制生物识别信息输入所施加的目标显示面板上的发射光源发射光线，发射光源发出的光线经过生物体遮挡反射进目标显示面板。
例如，假设识别模组23为指纹识别模组，如图2所示，当手指按压在第一显示面板21上时，第一显示面板21上的发射光源25发出的光线经过第一显示面板21上的手指遮挡反射进第一显示面板21，光调节件24改变从第一显示面板21进入的光线的传输路径，将从第一显示面板21进入的光线反射至识别模组23，识别模组23利用光调节件24反射的光线进行指纹识别。
同理，当手指按压在第二显示面板22上时，第二显示面板22上的发射光源25发出的光线经过第二显示面板22上的手指遮挡反射进第二显示面板22，光调节件24改变从第二显示面板22进入的光线的传输路径，将从第二显示面板22进入的光线反射至识别模组23，识别模组23利用光调节件24反射的光线进行指纹识别。
本公开实施例的移动终端，通过光调节件24将从第一显示面板21和第二显示面板22进入的光线发射至识别模组，从而可以利用一个识别模组实现两个显示面板上的生物识别信息的识别功能(如指纹识别功能)，降低了成本，且节约了占用的空间。
可选地，所述光调节件24包括第一反射面241和第二反射面242，所述第一反射面241朝向所述第一显示面板21倾斜设置，所述第一反射面241将从所述第一显示面板21进入的光线反射至所述识别模组23；所述第二发射面242朝向所述第二显示面板22倾斜设置，所述第二反射面242将从所述第二显示面板22进入的光线反射至所述识别模组23。
此时，如图2所示，光调节件24包括两个反射面，第一反射面241朝向第一显示面板21倾斜设置，利用第一反射面241能够改变从第一显示面板21进入的光线的传输路径，将从第一显示面板21进入的光线反射至识别模组 23，实现第一显示面板21上的生物识别信息的识别功能(如指纹识别功能)。第二反射面242朝向第二显示面板22倾斜设置，利用第二反射面242能够改变从第二显示面板22进入的光线的传输路径，将从第二显示面板22进入的光线反射至识别模组23，实现第二显示面板22上的生物识别信息的识别功能(如指纹识别功能)。从而可以利用一个识别模组实现两个显示面板上的生物识别信息的识别功能(如指纹识别功能)，降低了成本，且节约了占用的空间。
可选地，所述识别模组23为指纹识别模组。所述指纹识别模组包括光学透镜231和指纹传感器232，所述光学透镜231和所述指纹传感器232设置在所述第一显示面板21和所述第二显示面板22之间；所述光调节件24将从所述第一显示面板21和所述第二显示面板22进入的光线反射至所述光学透镜231。
此时，如图2所示，光调节件24将从第一显示面板21和第二显示面板22进入的光线反射至光学透镜231，光学透镜231再将光调节件24反射的光线传输至指纹传感器232，指纹传感器232利用光学透镜231传输的光线进行指纹识别，从而可以利用一个指纹识别模组实现双屏幕的指纹识别功能。
其中，本公开对指纹传感器232利用光线进行指纹识别的方法不做限定，可采用任意合理的方法，只要能实现指纹识别即可。
可选地，第一反射面241与第一显示面板21之间的夹角为锐角(如45°、60°等)，以保证第一反射面241能够将从第一显示面板21进入的光线反射至位于第一反射面241和第二反射面242一侧的识别模组23。可选地，第二反射面242与第二显示面板22之间的夹角也为锐角(如45°、60°等)，以保证第二反射面242能够将从第二显示面板22进入的光线反射至位于第一反射面241和第二反射面242一侧的识别模组23。
例如，如图2所示，移动终端包括相背设置的第一显示面板21和第二显示面板22，第一显示面板21和第二显示面板22均采用OLED面板，第一反射面241与第一显示面板21之间的夹角为45°，第二反射面242与第二显示面板22之间的夹角也为45°，识别模组23为指纹识别模组，指纹识别模组的光学透镜231和指纹传感器232设置于第一反射面241和第二反射面242的 一侧。此时当手指按在第一显示面板21或第二显示面板22上的时候，第一显示面板21或第二显示面板22的像素发光单元经过手指指纹遮挡反射回来的光线，经过第一反射面241或第二反射面242反射至光学透镜231，最终在指纹传感器232上实现指纹成像，从而利用一个指纹识别模组实现了第一显示面板21和第二显示面板22双屏幕的指纹识别功能，降低了成本，且节约了占用的空间。
可选地，如图3所示，所述第一反射面241和所述第二反射面242上分别设置有反光材料层26。
此时，利用第一反射面241和第二反射面242上的反光材料层26，能够将从第一显示面板和第二显示面板进入的光线反射出去，以改变光线的传输路径，将从第一显示面板和第二显示面板进入的光线反射至识别模组，从而利用一个识别模组实现两个显示面板上生物识别信息的识别功能(如指纹识别功能)。
可选地，所述反光材料层26采用的材料为铝或水银，但不限于此。
可选地，所述第一反射面241和所述第二反射面242在所述反光材料层26上还分别设置有透光材料层27。
此时，透光材料层27能够对反光材料层26起到保护作用，且透光材料层27具有透光效果，使从第一显示面板进入的光线能够穿过第一反射面241上的透光材料层27，被第一反射面241底层的反光材料层26反射出去，同样从第二显示面板进入的光线能够穿过第二反射面242上的透光材料层27，被第二反射面242底层的反光材料层26反射出去，不影响第一反射面241和第二反射面242具有的改变光路传输路径的效果。
可选地，所述透光材料层27采用的材料为玻璃，但不限于此。
可选地，如图2所示，所述光调节件24还包括底面243，所述第一反射面241、所述底面243和所述第二反射面242依次相连。
此时，第一反射面241、底面243和第二反射面242构成一个整体，具有一定的稳固性，且利于安装和拆卸。
可选地，所述第一反射面241、所述第二反射面242和所述底面243构成等腰三角形。
此时，第一反射面241、第二反射面242和底面243构成等腰三角形，进一步加强了结构的稳固性，且第一反射面241和第二反射面242保持对称，有利于第一反射面241和第二反射面242反射光线的均匀性。
可选地，所述第一反射面241和第二反射面242之间为空心结构。
此时，第一反射面241和第二反射面242之间为空心结构，减轻了结构质量，有利于终端轻量化设计。
或者所述第一反射面241和第二反射面242之间设置有填充物质。
此时，第一反射面241和第二反射面242之间设置有填充物质，进一步保证了结构的稳定性。
可选地，所述填充物质为树脂，但不限于此。
其中，可选用面积足够大的光学透镜231，以保证光学透镜231能够将第一反射面241和第二反射面242反射的所有光线均传输至光传感器232。如至少选用光学透镜231的面积大于第一反射面241在光学透镜231所在平面上的投影面积，且大于第二反射面242在光学透镜231所在平面上的投影面积。
下面对本公开实施例的移动终端的一具体应用实例举例说明如下。
如图2所示，移动终端包括相背设置的第一显示面板21和第二显示面板22，第一显示面板21和第二显示面板22均采用OLED面板。光调节件24包括第一反射面241、第二反射面242和底面243，三者构成等腰三角形(三角棱镜)，三角棱镜内部采用空心棱镜或者填充物质如树脂支撑。第一反射面241与第一显示面板21之间的夹角为45°，第二反射面242与第二显示面板22之间的夹角也为45°。第一反射面241、第二反射面242上分别依次设置有反光材料层26和透光材料层27，反光材料层26采用反光能力较强的铝。识别模组23为指纹识别模组，指纹识别模组的光学透镜231和指纹传感器232设置于光调节件24的一侧，且光学透镜231的面积大于第一反射面241在光学透镜231所在平面上的投影面积，且大于第二反射面242在光学透镜231所在平面上的投影面积。
如图2所示，当手指按压在第一显示面板21上，第一显示面板21上的像素发光单元发射的光线经过手指指纹遮挡反射进终端内，第一反射面241 改变从第一显示面板21进入的光线的传输路径，将其反射至光学透镜231，最终在指纹传感器232上实现指纹成像。同样的，当手指按压在第二显示面板22上时，第二显示面板22上的像素发光单元发射的光线经过手指指纹遮挡反射进终端内，第二反射面242从第二显示面板22进入的光线的传输路径，将其传输至光学透镜231，最终在指纹传感器232上实现指纹成像。从而利用一个指纹识别模组实现了双屏幕的指纹识别功能。
综上，本公开实施例的移动终端，通过光调节件将从第一显示面板和第二显示面板进入的光线发射至识别模组，从而可以利用一个识别模组实现两个显示面板上的生物识别信息的识别功能(如指纹识别功能)，降低了成本，且节约了占用的空间。

由于识别模组能够接收从第一显示面板和第二显示面板双屏幕进入的光线，当识别通过时，需要判断生物识别信息输入来源于哪个显示面板，这里，通过判断生物识别信息输入所施加的目标显示面板，能够准确、快速地确定出生物识别信息输入来源于哪个显示面板。
步骤403：在所述目标显示面板上执行识别通过对应的操作功能。
这里，用户在第一显示面板上进行生物识别信息输入时，第一显示面板为目标显示面板，用户在第二显示面板上进行生物识别信息输入时，第二显示面板为目标显示面板，在识别通过时，在目标显示面板(第一显示面板或第二显示面板)上执行识别通过对应的操作功能(如解锁屏幕)，从而利用一个识别模组实现了双屏幕的生物识别信息识别功能以及对双屏幕的控制功能。
