附图说明
图1是本发明的原理示意框图;
图2为本发明实施例一的终端的结构示意图;
图3为本发明的纳米悬浮层的局部放大图。
具体实施方式
为使本发明的发明目的、技术方案和有益效果更加清楚明了,下面结合附图对本发明的实施例进行说明,需要说明的是,在不冲突的情况下,本申请中的实施例和实施例中的特征可以相互任意组合。
纳米材料和技术成为新世纪最热门的应用科学之一。研究重点在于纳米规模的物质和设备的设计方法、组成、特性以及应用,尤其是由微观的自组织通向宏观尺度的应用。片状的纳米结构在外场(光场、磁场等)的驱动下,加上范德瓦耳斯力等微观力的组织,可以联接成大片宏观上非常平整的面。而撤去外场后纳米材料形成其他组织结构,这个宏观面又会可逆地消失。
如图2所示,本发明实施例提供一种具有镜子功能的显示屏,包括屏幕镜片20、液晶屏22和纳米悬浮层21,
所述纳米悬浮层21设置在所述屏幕镜片20和液晶屏22之间。
其中,屏幕镜片20和液晶屏22为现有技术的屏幕镜片20和液晶屏22,显示器的尺寸则可以根据效果优化,不做限定。
优选地,如图2所示,所述纳米悬浮层21包括上极板210、纳米材料层211和接地极板212,所述上极板210设置在所述屏幕镜片20和所述纳米材料层211之间,所述接地极板212设置在所述液晶屏22和所述纳米材料层211之间。
优选地,所述显示屏还包括磁性层23,所述磁性层23设置在所述液晶屏22的背面。
所述纳米悬浮层21的纳米材料为片状纳米材料。
所述片状纳米材料在厚度方向上的分布可以重叠,也可以不重叠。
如权利要求4所述的显示屏,其特征在于:所述片状纳米材料的厚度小于或者等于100nm。
所述片状纳米材料石墨烯片,所述悬浮液为十二烷基硫酸钠溶液。
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,
所述第一触发器,用于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,用于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,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;用于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;用于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现有采用的3V、5V、9V、12V,可以不单独为本发明所使用的上极板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。
实施例一
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。具体地,这里使用两侧各镀有10nm厚银的石墨烯片(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。如图3中片状纳米材料悬浮层21的局部放大图,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),在纳米材料层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。
实施例二
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。
虽然本发明所揭示的实施方式如上,但其内容只是为了便于理解本发明的技术方案而采用的实施方式,并非用于限定本发明。任何本发明所属技术领域内的技术人员,在不脱离本发明所揭示的核心技术方案的前提下,可以在实施的形式和细节上做任何修改与变化,但本发明所限定的保护范围,仍须以所附的权利要求书限定的范围为准。
