反射型显示器是利用指向显示器正面的环境光作为照明光源不需要背光源，能耗较低。
近来，随着信息技术的发展，透明显示技术愈发引起人们的关注。透明显示器含有一定程度的穿透性，施加电压时可在显示屏上显示信息，在不施加电压时可透过显示屏看到显示画面后方的背景，适用于建筑与车辆窗户及商店橱窗。除原有的显示功能外，更具备提供资讯等未来显示器特色，因此受到市场关注，未来可能会取代部分使用显示器的市场。因而，本申请实施例提供了一种显示器及电子设备，可以在透明状态和反射状态之间切换，且不需要额外的背光源，有效降低能耗以及提升响应速度。
本申请实施例提供一种显示器及电子设备，该显示器可以集成在电子设备中，该电子设备包括但不限于智能穿戴设备、智能手机、平板电脑、智能电视、广告牌等设备。
请参阅图1，图1为本申请实施例提供的电子设备的结构示意图。该电子设备100可以包括显示器10、控制电路20、以及壳体30。需要说明的是，图1所示的电子设备100并不限于以上内容，其还可以包括其他器件，比如还可以包括摄像头、天线结构、纹解锁模块等。
其中，显示器10设置于壳体30上。
其中，该显示器10为柔性显示器，可根据电子设备100的产品需求进行变形或弯曲。
例如，壳体30可以形成电子设备100的外部轮廓。
在一些实施例中，显示器10可以固定到壳体30上，显示器10的显示区域的正后方无壳体部分，或者壳体为透明材料。壳体的其他部位可以容纳控制电路20等器件。
在一些实施例中，壳体30可以为由柔性材料制成，比如为塑胶壳体或者硅胶壳体等。
其中，该控制电路20安装在壳体30中，该控制电路20可以为电子设备10的主板，控制电路20上可以集成有电池、天线结构、麦克风、扬声器、耳机接口、通用串行总线接口、摄像头、距离传感器、环境光传感器、受话器以及处理器等功能组件中的一个、两个或多个。
其中，该显示器10安装在壳体30中，同时，该显示器10电连接至控制电路20上，以形成电子设备10的显示面。该显示器10可以包括显示区域和非显示区域。该显示区域可以用来显示电子设备10的画面或者供用户进行触摸操控等。该非显示区域的顶部区域可以开设供声音、及光线传导的开孔，该非显示区域底部上可以设置指纹模组、触控按键等功能组件。
请参阅图2及图3，图2为本申请实施例提供的显示器的结构示意图，图3为本申请实施例提供的显示器的另一结构示意图。该显示器10包括设置在基板101上的反射层11、设置在该反射层11上的隔离层12、设置在该隔离层12上的固态相变层13和设置在该固态相变层13上的覆盖层14。
其中，该反射层11用于根据施加于该显示器10的电力在透明状态和反射状态之间切换。
其中，该隔离层12、固态相变层13和覆盖层14为透明的膜层，当该反射层11处于透明状态时，可透过该反射层11透视该显示器10背后的景象；当该反射层11处于反射状态时，可通过该反射层11对环境光的反射，以使得该显示器10上的画面进行显示。
例如，该隔离层12、固态相变层13和覆盖层14都是透明的膜层，当反射层11处于反射状态时，环境光穿过覆盖层14、固态相变层13和隔离层12，再经由反射层11反射而出，通过光的干涉作用达到显示特定颜色的效果。
在一些实施例中，当该反射层11处于反射状态时，该环境光依次穿过该覆盖层14、固态相变层13和隔离层12，再经由该反射层11反射而出，以使得该显示器10上的画面进行显示。
在一些实施例中，该显示器10处于关闭状态时，该反射层11处于透明状态；该显示器10处于打开状态时，该反射层11处于反射状态。
例如，该显示器10处于关闭状态时，该显示器10没有被施加电力，即没有连上电流或者未施加电压，则该反射层11处于透明状态，用户可透过该反射层11查看到该显示器10背后的景象。该显示器10处于打开状态时，该显示器10有被施加电力，即连上电流或者施加电压，该反射层11处于反射状态，通过该反射层11对环境光的反射，以使得该显示器10上的画面进行显示，以得到一个可透明的反射型显示器10。
其中，该可透明的反射型显示器10包括一系列像素点，每个像素点上均包括该反射层11、隔离层12、固态相变层13和覆盖层14。当该反射层11处于反射状态时，外界的环境光依次穿过该覆盖层14、固态相变层13和隔离层12，再经由该反射层11反射而出，以使得该显示器10上的画面进行显示。
在一些实施例中，该反射层11由过渡金属或者多个过渡金属的合金组成，未施加电力时该反射层11呈现透明状态，施加预设电力时该反射层11变成反射状态。
例如，该反射层11由过渡金属可切换反射镜（TMSM）组成，该过渡金属可切换反射镜可以包括过渡金属或多个过渡金属的合金。
例如，该反射层11是一种基于过渡金属可切换反射镜的反射层，可以根据施加于该显示器10的电力，在透明状态和反射状态之间切换。其中，过渡金属可切换反射镜不加电时呈现透明状态，施加一定的电压时变成反射状态。过渡金属可切换反射镜可以包括如铁、镍、铜、钴等过渡金属，或者其他过渡金属，或者多个过渡金属的合金。
在一些实施例中，该隔离层12用于调节该显示器10的反射率，该显示器10的反射率由该隔离层12的厚度来确定。
例如，可以根据该显示器10的产品性能要求对应的反射率来设置该隔离层12的厚度。
在一些实施例中，该固态相变层13用于在电压驱动下使该显示器10中的像素点的颜色进行转换。
例如，该固态相变层13由相变材料组成，比如该固态相变层13可以由锗、锑、碲 (Ge、Sb、Te)合金组成，在电压驱动下该固态相变层13可以在晶态和非晶态之间可逆转变，引起相变材料折射率的变化，从而使得每个像素点的颜色发生改变。其中，被驱动的电压小于10V。
其中，相变材料还可以包括硫系化合物及其合金或过渡金属氧化物。
其中，该固态相变层13可以为超薄固态相变层，其厚度小于50纳米。
在一些实施例中，该覆盖层14用于接收外部施加的电压，该固态相变层13用于在通过该覆盖层14接收到的电压的驱动下使该显示器10中的像素点的颜色进行转换。
例如，该覆盖层14电性连接于该固态相变层13，该覆盖层14接收到的电压施加于该固态相变层13上。
在一些实施例中，该固态相变层13用于在电压驱动下在晶态和非晶态之间进行转变，以改变该固态相变层13的折射率，进而改变该显示器10中的每个像素点的颜色。
例如，该固态相变层13的折射率可以通过施加电压来发生可逆的改变。比如，对相变材料施加一个时间长且强度中等的电压，相变材料的温度可以升高到结晶温度以上熔化温度以下的温度区间，并保持一定的时间，晶格此时有序排列形成晶态，实现由非晶态向晶态的转变；比如，对相变材料施加一个时间短而强度高的电压，使相变材料温度可以升高到熔化温度以上，使晶态的晶格遭到破坏，施加的电压非常短导致相变材料经快速冷却至结晶温度以下，使相变材料固定于非晶态，实现由晶态向非晶态的转变，进而引起相变材料折射率的变化，从而使得每个像素点的颜色发生改变，以使得该显示器10上的画面进行显示。
在一些实施例中，该固态相变层13可以设计成多层结构，例如设计成双层结构、三层结构、四层结构或者其他多层结构，不同层之间可以设置不同的相变材料，可以单独控制每一层的相变材料的状态，通过对不同层的固态相变层施加不同的电压或者激光脉冲，可以使得不同层的相变材料呈现不同的状态，以使得显示器10实现多种不同颜色的显示，以丰富显示器10的显示色彩。
例如，如图3所示，该固态相变层13可以设计成三层结构，该固态相变层13包括第一固态相变层131，第二固态相变层132和第三固态相变层133。例如，第一固态相变层131相变材料为GeTe合金，第二固态相变层132的相变材料为SbTe合金，第三固态相变层133的相变材料为GeSbTe合金。三层结构的相变材料可以单独控制，以实现多种不同颜色的显示。
在一些实施例中，该显示器10中的所有像素点通过有序排列形成用于显示画面的显示阵列。
比如，通过垂直排列、水平排列、交错排列、堆叠排列等任一种或多种的有序排列以形成可以显示画面的显示阵列。
