以下是对本文详细描述的主题的概述。本概述并非是为了限制权利要求的保护范围。
在日常生活中，人们通过移动终端在公共场所使用QQ、微信等通信软件时，常常遇到屏幕上显示的内容容易被他人窥探的情形。对于该种情形，当用户在使用支付应用输入密码进行支付等保密环节，很容易因他人偷看造成信息泄露的隐患。而对于用户来说，此时刻意进行遮挡的话，操作是非常不方便的，而对于他人也是非常不友好的。

在阅读并理解了附图和详细描述后，可以明白其他方面。
附图概述

图2为本公开实施例所提供的移动终端显示方法的原理示意图；
图3为本公开实施例中LED配合光栅应用实例示意图；
图4为本公开实施例中所提供的移动终端的结构原理框图。
本公开的较佳实施方式
下面结合附图对本公开的实施方式进行描述。
方法实施例
如图1所示，本公开实施例所提供的移动终端显示方法，可以包括：
步骤101，检测用户的位置信息；
在该步骤中，移动终端可以通过摄像头来采集用户的面部信息，根据面部信息来确定用户的位置。可选地，移动终端中配置有双摄像头，该双摄像头可以固定设置于移动终端的前面板上，还可以为旋转式摄像头，通过旋转的方式可以将两个摄像头调整至前面板上。
在检测用户的位置信息时，可以通过双摄像头采集用户的面部图像，基于预设的图像识别算法来识别用户眼睛所在的位置。可以根据用户人眼所在图像位置确定用户的位置。可选地，基于人眼位置确定用户的位置信息时，本公开实施例通过如下方式实现：
获取两眼位置所在的中心位置；
确定中心位置与双摄像头中每个摄像头所在直线与双摄像头所在直线的夹角，以基于夹角表示用户所在位置。
这里，在实现时，由于双摄像头可以分别获得两眼的中心位置在每个采集图像中的位置。根据该位置信息以及双摄像头的焦距等参数可以直接获取上述直线的夹角信息。该夹角信息即为用户相对于移动终端屏幕的角度信息，根据该角度信息可以调整显示屏中的点亮位置。
可选地，当双摄像头检测移动终端前有多个人的人眼信息时，可以根据人眼位置确定移动终端的用户。这里，可以根据多个人中每个人的两眼中心位置到双摄像头所在的直线距离确定该用户，可选地，选取该距离最短的人为用户。该距离的计算，可以根据两眼的中心位置在每个采集图像中的位置、双摄像头的焦距以及双摄像头之间的间距来直接确定。对于双摄像头测距的实现已属于本领域技术人员所熟知的技术，例如，可以参考“双摄像头测距的开放源代码计算机视觉类库(Open source Computer Vision library，OpenCV)实现”(http://blog.csdn.net/scyscyao/article/details/5562024)，因此这里不再赘述。
步骤102，根据用户的位置信息调整显示屏中发光二级管(Light-Emitting  Diode，LED)阵列的点亮位置，以基于点亮位置的LED阵列将显示内容通过设置于显示屏表面的光栅投影至用户所在的位置。
在该步骤中，移动终端可以配置有LED阵列驱动、LCD显示屏、以及设置于LCD显示屏上的光栅膜。其中，LED阵列驱动可以驱动指定的位置的LED阵列点亮；LCD显示屏则可以设置为控制显示的特定内容；光栅膜可以控制将经LED阵列点亮而投射的显示内容在指定的空间区域中进行显示。
这里，在移动终端中可以预设位置信息与LED阵列点亮位置的映射表，在根据用户的位置信息调整显示屏中LED阵列的点亮位置时，根据该映射表可以直接获取与用户的位置信息相对应的LED阵列的点亮位置。这里，在映射表中用户位置和点亮的LED数量和位号可以是一一对应。通过预先存储的方式，可以方便随时调用，缩短从双摄像头捕获位置到驱动LED的时间，以便做到快速响应，提高处理速度。
如图2所示，图2中11为双摄像头，12为LED阵列，13为光栅，14为LCD显示屏。这里，假设LED阵列为一字排列，并且有21颗灯，间距为4mm，从右到左编号0至20号灯。在水平范围内，由一组角度坐标(α，β)可以唯一确定用户位置。其中，α,β分别为人眼中心位置与第一摄像头的连线，与双摄像头连线的夹角。该角度信息决定电亮的LED位置(这里1表示点亮，0表示熄灭)，因此对应表可以有此信息初步给出，形式可以如表1所示：
角度坐标(α，β) LED点亮位置(L1，L2，……L20)
(0，0) (0,0，……0)
(10，5) (1，1，0，0，……0，0，1，1)
(20，10) (1，0，1，0,……0，1，0，0)
…… ……
(α1，β1) (L1，L2，……L20)
(α2，β2) (L1’，L2’，……L20’)
(95，85) (0，0，……1，1，1，1，0,……，0)
表1
上述的映射表仅说明了在0至90°范围内的映射表，由于移动终端的对 称性，对于90°至180°范围的映射表与上述的映射表做对称处理即可，这里不再进行说明。但是可以说明的是，上述的映射表仅为示例。在实际使用时，可以根据用户的使用情况对点亮位置最相应的调整，做到整个移动过程中亮度合适均匀，即可完成映射表的调整。
在根据角度信息确定LED点亮的位置后，通过LED点亮指定区域，再通过光栅对光路做相应的处理，可以保证最终的光线投影至用户所在的位置，而其他未点亮的位置由于光栅的作用，则无法看到显示的内容。原理可以如下：
图3所示为LED配合光栅应用实例示意图。本公开实施例的光路相对于此图示复杂得多，在此做简单说明。其中，左侧三个圆圈为LED，发出的光线经过光栅透镜投影到右方，并将右方分割成许多菱形区域，其中只有标注方块的区域包含所有三个LED灯光源发出的光线，才能被人眼识别成清晰的图像，其他区域并未包含所有LED投射的光线，因此无法完全显示屏幕的内容，因此其他部分所见为模糊的图像。
基于上述可知，本公开实施例所提供的移动终端显示方法，通过对用户所在的位置进行检测，根据用户的位置可以确定点亮的LED阵列，只有相应的位置的LED阵列点亮后透过光栅的处理，可以确保只有用户所在的位置可以看到显示的内容。而当用户发生位置移动时，双摄像头重新捕获用户位置信息，并根据接收到新的位置信息时，再次重新调整点亮相应的LED阵列。因此，本公开实施例针对用户在水平范围内大范围移动时，能够跟踪用户位置，并根据用户的位置动态调整显示内容在空间的显示区域，从而避免显示内容被其他用户窥探的情形，有效保证用户的信息安全。
