本发明实施例还提供一种具有镜子功能的显示屏的控制装置，包括：上述显示屏、第一触发器、第二触发器和控制器，其中：
所述第一触发器，设置为在满足第一预定条件时，向所示控制器发送开启触发信号；
所述第二触发器，设置为在满足第二预定条件时，向所示控制器发送关闭触发信号；
所述控制器，设置为在接收到所述关闭触发信号时，控制所述磁性层23提供垂直于所述显示屏的静磁场；以及设置为在接收到所述开启触发信号时，控制所述上极板提供电压，或者，控制所述上极板提供电压并且控制所述磁性层23提供垂直于所述显示屏的静磁场。
本发明实施例的显示屏在屏幕镜片20和液晶屏22之间加上一层片状纳米材料悬浮层21，所述片状纳米材料对光有高的反射率。通过控制器加外场(磁场、电场等)调控使使片状纳米材料分布变化。实现镜面功能时，通过控制器加外场调控使片状纳米材料平行于显示屏平铺分布，组成反射镜面，显示屏会自然成为一面镜子。当终端屏幕显示工作时，控制器收到指令，通过外场的改变，将片状纳米材料调控为垂直于显示屏呈阵列分布，此时，阵列密度比较小，占空比比较低，以至于对光透过的影响比较小(在20％以下)，显示光线从阵列空隙间正常透过，不被片状纳米材料阻挡。
其中，所述第一预定条件可以为亮屏信号或者解锁信号或者用户输入的镜面功能关闭信号，所述第二预定条件可以为黑屏信号或者锁屏信号或者接收到用户输入的镜面功能开启信号。
如图1所示，本发明实施例的具有镜子功能的显示屏的控制方法，包括：
在接收到所述关闭触发信号时，控制所述磁性层23提供垂直于所述显示屏的静磁场；在接收到所述开启触发信号时，控制所述上极板210提供电压，或者，控制所述上极板210提供电压并且控制所述磁性层23提供垂直于所述显示屏的静磁场。
所述上极板210提供的电压和所述磁性层23提供的静磁场根据以下的一项或者多项确定：
采用的纳米材料、所述纳米材料的面积、所述纳米材料的厚度、切换灵敏度。
所述上极板210提供的电压一般为1-12V，其中，可以采用手机内部芯片或者单元已经采用的3V、5V、9V、12V，可以不单独为本发明实施例所使用的上极板210变压。终端屏幕显示功能和镜面功能的切换灵敏度也是确定上极板提供的电压大小和所述磁性层23提供的静磁场大小的一个因素。
应用示例一
如图1和2所示，在屏幕镜片20与液晶屏22之间，夹着片状纳米材料悬浮层21。如图3中片状纳米材料悬浮层21的局部放大图，片状纳米材料悬浮层21包括透明上极板210、纳米材料悬浮液(即为上述纳米材料层)211和透明接地极板212，其中，纳米材料悬浮液211被透明上极板210和透明接地极板212所夹(透明极板是氧化铟锡透明导电膜)，在终端屏幕显示光透时，在上极板210上加一定电压(例如3V)，在纳米材料悬浮液211中形成垂直于显示屏表面的电场，此电场可以驱动片状纳米材料垂直于两极板之间。其中，纳米材料悬浮液211包括纳米材料和悬浮液，这里使用两侧分别镀有10nm厚银(镀银的厚度此处仅为示例，只要能反射即可)的石墨烯片(尺寸1um-10um之间)做片状纳米材料，溶有SDS(十二烷基硫酸钠，一种分散液)的水做溶剂，SDS是为避免石墨烯片的凝聚。在实现镜面功能时，底部磁性层23提供垂直于面的静磁场。在此静磁场的作用下，石墨烯片由于其抗磁性而垂直于磁场排布，呈平行于显示屏表面水平平铺分布，组成一个反射面。
应用示例二
如图1和2所示，本实施例中底部磁层23总是存在，片状纳米材料悬浮层21的缺省状态就是一面镜子。这样，在手机黑屏，甚至关断电源时，屏幕会是一面银反射镜，而当显示屏被唤醒，对片状纳米材料悬浮层21的上极板210加电压，屏幕又会正常透光。
此时可以减少切换外场的。由于电场的影响比磁场的影响可以大很多，其扭转力矩比可超过104，所以终端屏幕显示光透时，磁场的效果几乎被完全抵消，片状纳米材料可以形成直立性很好的阵列分布，本实施例中片状纳米材料的厚度约20nm，相对它的面尺寸1um-10um来说非常小，所以相对来说竖直阵列的密度是很小的，占空比极低(0.5％以下)，对于从显示屏射出的光来说，透过几乎不会受其影响。
本领域普通技术人员可以理解上述方法中的全部或部分步骤可通过程序来指令相关硬件完成，上述程序可以存储于计算机可读存储介质中，如只读存储器、磁盘或光盘等。可选地，上述实施例的全部或部分步骤也可以使用一个或多个集成电路来实现。相应地，上述实施例中的各模块/单元可以采用硬件的形式实现，也可以采用软件功能模块的形式实现。本发明实施例不限制于任何特定形式的硬件和软件的结合。
工业实用性
本发明实施例利用纳米材料的自组织技术提供一种将显示屏在黑屏时切换成一面镜子使用的方案，在显示屏恢复显示时又不影响到显示屏光的透过。
