其中，显示装置100可以为液晶显示装置(Liquid Crystal Display，简称LCD)；显示装置100也可以为电致发光显示装置或光致发光显示装置。在 显示装置100为电致发光显示装置的情况下，电致发光显示装置可以为有机电致发光显示装置(Organic Light-Emitting Diode，简称OLED)或量子点电致发光显示装置(Quantum Dot Light Emitting Diodes，简称QLED)。在显示装置100为光致发光显示装置的情况下，光致发光显示装置可以为量子点光致发光显示装置。

在一些实施例中，如图2所示，沿镜面切换屏2指向显示模组1的方向，显示模组1依次包括第二吸收型偏光片3和显示面板12等其它电子配件。在显示装置100为液晶显示装置的情况下，显示装置100还包括背光组件，背光组件被配置为向显示面板12提供显示画面所需要的光线。
其中，显示面板12在参考面上的正投影，位于镜面切换屏2在参考面上的正投影内。需要说明的是，参考面为镜面切换屏2远离显示面板12的表面所在的平面。
在一些实施例中，如图5所示，显示面板12包括显示区A1和位于显示区A1至少一侧的周边区A2。
此处，显示区A1为显示图像的区域，显示区A1被配置为设置亚像素P。周边区A2为不显示图像的区域，周边区A2可以被配置为布置显示画面所需要的各种信号线；周边区A2也可以被配置为布置向显示区A1的亚像素P输出扫描信号的栅极驱动电路、以及向显示区A1的亚像素P输出数据信号的源极驱动电路等。

在一些实施例中，如图6所示，显示基板121还包括设置于薄膜晶体管1210和阳极1211之间的平坦层1215。
在一些实施例中，如图6所示，显示基板121还包括第一保护层1216，第一保护层1216设置于阴极1213背离第一衬底Sub1的一侧。
在一些实施例中，显示面板12为液晶显示面板，如图7所示，液晶显示面板包括相对设置的阵列基板123和对盒基板124、以及设置于阵列基板123和对盒基板124之间的液晶盒125。
阵列基板123的每个亚像素P(参阅图5)均包括位于第一衬底Sub1上的薄膜晶体管1230和像素电极1231。像素电极1231与薄膜晶体管1230的源极或漏极电连接，图7中以像素电极1231和薄膜晶体管1230的漏极电连接进行示意。
在一些实施例中，如图7所示，阵列基板123还包括公共电极1232，公共电极1232设置于第一衬底Sub1上。
示例性地，像素电极1231和公共电极1232可以设置于同一层，在此情况下，像素电极1231和公共电极1232均为包括多个条状子电极的梳齿结构。
示例性地，像素电极1231和公共电极1232也可以设置于不同层，在此情况下，如图7所示，像素电极1231和公共电极1232之间设置有第一绝缘层1233。
此外，在公共电极1232设置于薄膜晶体管1230和像素电极1231之间的情况下，如图7所示，公共电极1232与薄膜晶体管1230之间设置有第二绝缘层1234。
在另一些实施例中，对盒基板14包括第二衬底Sub2和公共电极1232，公共电极1232设置于第二衬底Sub2上。
如图7所示，液晶显示面板还包括彩色滤光层CF和黑矩阵图案BM。其中，彩色滤光层CF至少包括设置于红色亚像素中的红色光阻单元、设置于绿色亚像素中的绿色光阻单元以及设置于蓝色亚像素中的蓝色光阻单元。黑矩阵图案BM被配置为将从不同亚像素发出的光间隔开，并且具有减少外界环境光进入液晶显示面板内部后产生反射光线的作用。
如图7所示，液晶显示面板还包括设置于对盒基板124远离液晶盒125一侧的上偏光片126，以及设置于阵列基板123远离液晶盒127一侧的下偏光片127。
需要说明的是，上偏光片126(参阅图7)与第二吸收型偏光片3(参阅图2)可以为同一偏光片。此外，液晶盒125包括配向膜、封框胶和液晶分子，配向膜用于配置液晶分子的初始排列方式，封框胶用于防止液晶分子泄露、支撑并连接第一衬底Sub1和第二衬底Sub2，本公开在此不做详细说明。
在一些实施例中，如图2所示，沿显示面板12指向镜面切换屏2的方向，镜面切换屏2包括依次设置的反射型偏光片21、第一透明基板22、第一透明电极层23、第一配向膜24、液晶层25、第二配向膜26、第二透明电极层27、第二透明基板28和第一吸收型偏光片29。
需要说明的是，液晶层25包括封框胶251和位于封框胶251、第一配向膜24和第二配向膜26之间的液晶分子，本公开在此不做详细说明。
此处，在形成液晶层25的过程中，需要先形成封框胶251以及、第一配向膜24和第二配向膜26，其中，封框胶251上设有灌晶口，通过灌晶口将液晶分子灌入至封框胶251、第一配向膜24和第二配向膜26之间，最后通过封孔胶将灌晶口封住，防止液晶分子流出。需要说明的是，封框胶251可以设有多个灌晶口，以提高生产效率；示例性地，封框胶251上设有两个灌晶口。
其中，反射型偏光片21包括多层膜反射式偏光片(Advance polarizer film，简称：APF)、反射式偏光镜(Reflector polarizer mirror，简称：RPM)、光学增亮膜片(Dual brightness enhancement film，简称：DBEF)或金属网丝反射型偏光膜中的任一种。
示例性地，反射型偏光片21的透过轴与第一吸收型偏光片29的吸收轴大致垂直，第一配向膜24的取向方向与反射型偏光片21的透过轴大致平行，第二配向膜26的取向方向与第一吸收型偏光片29的吸收轴大致平行。也就是说，液晶层25靠近第一配向膜24的液晶分子的长轴方向与反射型偏光片 21的透过轴大致平行，液晶层25靠近第二配向膜26的液晶分子的长轴方向与第一吸收型偏光片29的吸收轴大致平行，液晶分子呈层状排列，层内分子排列方向相同，层与层之间的液晶分子排列方向相错位，整体分子结构呈现螺旋状。
其中，镜面切换屏2远离显示面板12的一侧的非偏振光以及显示面板12所发出的非偏振光，均可以被分解为偏振方向相互垂直的第一偏振光和第二偏振光，第一偏振光的偏振方向与第一吸收型偏光片29的吸收轴大致平行，即与反射型偏光片21的透过轴大致垂直，第二偏振光的偏振方向与第一吸收型偏光片29的吸收轴大致垂直，即与反射型偏光片21的透过轴大致平行。
在显示装置100处于自然状态(第一透明电极层23和第二透明电极层27之间没有产生电场)下，镜面切换屏2远离显示面板12的一侧的非偏振光，射向第一吸收型偏光片29，该非偏振光的第一偏振光被第一吸收型偏光片29吸收，第二偏振光透过第一吸收型偏光片29、第二配向膜26进入液晶层25，穿过液晶层25后，第二偏振光的偏振方向偏转90°转化为第一偏振光，该第一偏振光的偏振方向与反射型偏光片21的透过轴大致垂直，第一偏振光透过第一配向膜24被反射型偏光片21反射回液晶层25，再次穿过液晶层25后，第一偏振光的偏振方向偏转90°转化为第二偏振光，该第二偏振光透过第二配向膜26、第一吸收型偏光片29射向外界。此时，如果各层均为理想的介质材料，光的衰减会趋向于零，镜面切换屏2的反射率达到最高，反射率大于或等于40％，镜面切换屏2处于反射率最高的镜面状态。
在显示装置100处于显示状态(第一透明电极层23和第二透明电极层27之间具有较强的电场)下，液晶分子沿着电场方向排列，例如，液晶分子克服第一配向膜24和第二配向膜26锚定作用力，呈现大致垂直排列的情况下(液晶分子的长轴方向与镜面切换屏2的厚度方向大致平行)，液晶分子的旋光性消失，即液晶层25对偏振光的调制不起作用，偏振光仍以原来的方向经过。在这种情况下，显示面板12所发出的非偏振光，射向反射型偏光片21，该非偏振光的第一偏振光被反射型偏光片21反射，第二偏振光透过反射型偏光片21、第一配向膜24进入液晶层25，穿过液晶层25后，第二偏振光的偏振方向不变，第二偏振光透过第二配向膜26、第一吸收型偏光片29射向外界。此时，如果各层均为理想的介质材料，光的衰减会趋向于零，镜面切换屏2的透射率达到最高，透射率大于或等于90％，镜面切换屏2处于透射率最高的透明状态。
由上述可知，反射型偏光片21的透过轴与第一吸收型偏光片29的吸收 轴大致垂直，第一配向膜24的取向方向与反射型偏光片21的透过轴大致平行，第二配向膜26的取向方向与第一吸收型偏光片29的吸收轴大致平行。以这种方式设置，在自然状态下，镜面切换屏2呈现反射率最高的镜面状态，显示装置100可以清晰的呈现外界环境的镜像；在显示画面时，镜面切换屏2呈现透射率最高的透明状态，显示装置100可以清晰的呈现显示画面，耗电量较低。
此外，为了避免显示面板12反射的光与显示面板12发出的光产生干扰，在一些实施例中，如图2所示，上述显示装置100还包括第二吸收型偏光片3，第二吸收型偏光片3设置于显示面板12与镜面切换屏2之间，第二吸收型偏光片3的吸收轴与反射型偏光片21的透过轴大致垂直。在这种情况下，在显示装置100处于显示状态下，显示面板12所发出的非偏振光的第一偏振光被第二吸收型偏光片3吸收，第二偏振光依次穿过第二吸收型偏光片3、反射型偏光片21、第一配向膜24、液晶层25、第二配向膜26以及第一吸收型偏光片29射向外界，避免显示面板12所发出的非偏振光的第一偏振光被反射型偏光片21反射到显示面板12上，再次反射对显示画面造成干扰，影响显示效果。
需要说明的是，在显示面板12为液晶显示面板的情况下，图7中的上偏光片126与图2中的第二吸收型偏光片3可以为同一偏光片。在显示面板12为电致发光显示面板的情况下，第二吸收型偏光片3可以为电致发光显示面板出光侧的圆偏光片。
其中，在安装偏光片(包括第一吸收型偏光片29、第二吸收型偏光片3、反射型偏光片21等)的过程中，偏光片相对的两个主表面分别设有包括粘接膜和保护膜，保护膜的上设有延伸出保护膜外的操作贴片。在安装偏光片时，操作员可以捏住操作贴片，将偏光片对位粘接到载体上，最后揭掉操作贴片及保护膜，即可形成偏光片，操作简单，工艺难度低。
在一些实施例中，如图8和图9所示，显示装置100还包括第一光敏传感器41和驱动板5。
其中，第一光敏传感器41被配置为实时感测镜面切换屏2远离显示面板12的一侧的环境光的光线强度。驱动板5与第一光敏传感器41和镜面切换屏2电连接。
在一些实施例中，驱动板5被配置为，在第一光敏传感器41感测的光线强度大于或等于第一预设光线强度的情况下，向镜面切换屏2发送第一控制信号，以降低镜面切换屏2的反射率，从而达到防眩目的目的。
需要说明的是，第一预设光线强度可以根据实际情况进行设定，本公开不做具体限定。
在另一些实施例中，驱动板5还可以被配置为，在镜面切换屏2远离显示面板12的一侧的环境光的光线强度，与显示面板12远离镜面切换屏2的一侧的环境光的光线强度之差，大于或等于第二预设光线强度的情况下，向镜面切换屏2发送相应的控制信号，以降低镜面切换屏2的反射率，从而达到防眩目的。
示例性地，如图2和图8所示，显示装置100还包括第二光敏传感器42，第二光敏传感器42设置于显示面板12远离镜面切换屏2的一侧。其中，第二光敏传感器42被配置为实时感测显示面板12的背光侧的环境光的光线强度。驱动板5还与第二光敏传感器42电连接，驱动板5还被配置为，在第二光敏传感器42感测的光线强度与第一光敏传感器41感测的光线强度之差，大于或等于第二预设光线强度的情况下，向镜面切换屏2发送第三控制信号，以降低镜面切换屏2的反射率，从而达到防眩目的。
需要说明的是，第二预设光线强度可以根据实际情况进行设定，本公开不做具体限定。
此外，上述驱动板5还可以针对第一光敏传感器41感测的光线强度与多个预设光线强度进行多次判断，每次判断的过程为，判断第一光敏传感器41感测的光线强度是否大于或等于相应的预设光线强度，并在第一光敏传感器41感测的光线强度大于或等于相应的预设光线强度的情况下，发送相应的控制信号，以将镜面切换屏2的反射率降低至相应的范围内。
在一些实施例中，如图1、图2和图9所示，显示装置100还包括第一柔性电路板6，第一柔性电路板6包括绑定部61、元器件部62和走线部63，绑定部61与镜面切换屏2电连接，第一光敏传感器41设置于元器件部62靠近镜面切换屏2的表面，走线部63设有与绑定部61的绑定焊盘610和第一光敏传感器41电连接的走线，该走线被配置为传输镜面切换屏2的控制信号以及第一光敏传感器41的感测信号的走线，及驱动板5通过第一柔性电路板6的走线部63分别与第一光敏传感器41及镜面切换屏2电连接。在这种情况下，第一光敏传感器41及其与驱动板5连接的电路走线、镜面切换屏2与驱动板5连接的电路走线集成在同一柔性电路板上，可以节省电路走线的布置空间，降低物料成本。
需要说明的是，第一柔性电路板6的走线部63远离镜面切换屏2的一端设有第一连接部631，第一连接部631与驱动板5对应的接口电连接。其中， 驱动板5能够通过第一柔性电路板6弯折至显示面板12远离镜面切换屏2的一侧。
其中，绑定部61、元器件部62以及走线部63的相对位置关系并不唯一。示例性地，如图1和图9所示，绑定部61与元器件部62均位于走线部63靠近镜面切换屏2的端部，这样可以提高电路走线排布的规律性，提高走线部63的规整性，降低走线部63所占用面积。在此基础上，绑定部61与元器件部62之间具有缝隙SL，以使绑定部61与元器件部62相互分离。这样的话，在将绑定部61与镜面切换屏2通过压接工艺绑定的过程中，元器件部62受到压接工艺的影响较小；并且，在绑定部61与镜面切换屏2绑定连接后，可以降低第一光敏传感器41与镜面切换屏2之间的挤压力，提高可靠性。
示例性地，绑定部61靠近元器件部62的边界，与元器件部62靠近绑定部61的边界之间的最小距离为25.55mm～25.95mm。例如，绑定部61靠近元器件部62的边界，与元器件部62靠近绑定部61的边界之间的最小距离为25.55mm、25.65mm、25.75mm、25.85mm和25.95mm中的任一者。
在一些实施例中，参阅图2和图9，上述第一透明基板22在参考面上的正投影，位于第二透明基板28在参考面上的正投影内。其中，第二透明基板28超出第一透明基板22的边缘部分形成第一台阶280，第一台阶280靠近显示面板12的一侧设有绑定引脚，第一柔性电路板6的绑定部61设有绑定焊盘610，绑定焊盘610与绑定引脚电连接。
在此基础上，第一光敏传感器41与第一台阶280靠近显示面板12的表面连接。示例性地，如图2、图9和图11所示，第一光敏传感器41包括基座411和光敏芯片412，基座411的第一表面411A设有安装槽，光敏芯片412设置于安装槽内，基座411的第二表面411B设有感光孔413，光敏芯片412被配置为，通过感光孔413感测镜面切换屏2远离显示面板12的一侧的环境光的光线强度。第一表面411A和第二表面411B为基座411相对的两个表面。
其中，基座411的第一表面411A与第一柔性电路板6连接，基座411的第二表面411B与第一台阶280靠近显示面板12的一侧粘接。此处，粘接避让开上述感光孔413，以保证光敏芯片412感测镜面切换屏2远离显示面板12的一侧的环境光的光线强度的精度。
这里，镜面切换屏2包括感光区，第一光敏传感器41在镜面切换屏2的正投影与感光区至少部分重合。
示例性地，镜面切换屏2的第一台阶280对应的区域中至少部分为感光区，即第二透明基板28超出第一透明基板22的边缘部分中至少部分区域不 做任何处理以确保透光性，例如在该区域仅设置有第二透明基板本身，第一光敏传感器41在镜面切换屏2的正投影位于感光区内。
示例性地，第一台阶280上设有通光孔，该通光孔对应的区域为感光区，即在第二透明基板28超出第一透明基板22的边缘部分上进行开孔，形成通光孔作为感光区；第一光敏传感器41包括基座411和光敏芯片412，基座411上的感光孔413的边界在镜面切换屏2的正投影，与通光孔的边界近似重合。
在此基础上，上述感光区可以设置导光结构，导光结构被配置为，将镜面切换屏2远离显示面板12的一侧的环境光，传导至第一光敏传感器41的光敏芯片412。例如，导光结构设置于上述通光孔内，以将镜面切换屏2远离显示面板12的一侧的环境光传导至第一光敏传感器41的光敏芯片412，降低环境光传导过程中的损失，保证光敏芯片412感测镜面切换屏2远离显示面板12的一侧的环境光的光线强度的精度。
由于第一光敏传感器41需要接收外界环境光，显示装置100的显示侧可以直观的看到第一光敏传感器41，为了提高显示装置100的规整性，如图1和图9所示，第一光敏传感器41在参考面上的正投影的中心，与第一台阶280在参考面上的正投影的中心大致重合。这样的话，显示装置100在第一光敏传感器41的左右两侧对称分布，整体结构规整，更加美观。
在一些实施例中，如图1和图2所示，上述显示面板12和镜面切换屏2在参考面的正投影大致为梯形，该梯形相互平行的两条边中最长的边为第一边界。在此基础上，第二透明基板28靠近第一边界的边缘部分超出第一透明基板22靠近第一边界的边缘部分，形成第一台阶280。以这种方式设置，第一台阶280的区域较大，便于设置第一光敏传感器41以及便于绑定部61与镜面切换屏2的电连接。
需要说明的是，“大致为梯形”是指，显示面板12和镜面切换屏2在参考面的正投影的形状整体上呈梯形形状，但是并不局限为标准的梯形。即，这里的“梯形”不但包括基本梯形的形状，而且考虑到工艺条件，还包括类似于梯形的形状。例如，梯形的拐角处为弯曲状，即拐角处平滑，使得显示面板12和镜面切换屏2在参考面的正投影在平面图的形状为圆角梯形。
示例性地，显示装置100应用于汽车的后视镜10(参阅图10)，后视镜10的外轮廓大致为梯形，其下边界即为第一边界。也就是说，第一台阶280对应位于镜面切换屏2的下边缘，柔性电路板6在镜面切换屏2的下侧与镜面切换屏2电连接。
在一些实施例中，如图2所示，第二吸收型偏光片3在参考面上的正投 影，位于显示面板12在参考面上的正投影内，显示面板12超出第二吸收型偏光片3的边缘部分形成第二台阶120，且第一台阶280在参考面上的正投影，与第二台阶120在参考面上的正投影至少部分重合。例如，第一台阶280在参考面上的正投影，与第二台阶120在参考面上的正投影大致重合。其中，第一柔性电路板6在第一台阶280与第二台阶120重合的区域与第一台阶280绑定电连接。在这种情况下，显示装置100还包括支撑件9，支撑件9的一端至少与第一柔性电路板6抵靠，另一端与第二台阶120抵靠，以对第一柔性电路板6起到支撑的作用。示例性地，支撑件9的一端可以与第一柔性电路板6以及第一台阶280抵靠，另一端与第二台阶120抵靠，这样支撑件9对第一柔性电路板6提供的支撑力较大，支撑效果较高。
需要说明的是，在显示面板12为液晶显示面板的情况下，对盒基板124和液晶盒125在参考面上的正投影，可以与第二吸收型偏光片3在参考面上的正投影大致重合；对盒基板124和液晶盒125在参考面上的正投影，位于阵列基板123在参考面上的正投影内，且阵列基板123超出第二吸收型偏光片3的边缘部分形成第二台阶120。在显示面板12为电致发光显示面板的情况下，显示面板12超出第二吸收型偏光片3，且显示面板12超出第二吸收型偏光片3边缘部分形成第二台阶120。其中，图2中以显示面板12为液晶显示面板为例进行示意(图2中未示意出液晶盒125)。
在此基础上，如图2所示，支撑件9的材料可以是不透光的材料，也可以在支撑件9的侧壁上设有遮光膜。这样的话，支撑件9在保证支撑性能的同时，还可以有效避免漏光。
其中，支撑件9的弹性模量大于或等于3GPa。示例性地，支撑件9的材料包括泡棉、聚酰亚胺(Polyimide，简称PI)和聚对苯二甲酸类(Polyethylene terephthalate，简称PET)塑料中的至少一种。
此外，参阅图2，上述第一柔性电路板6在支撑件9远离第二吸收型偏光片3的一侧延伸至显示面板12的背光侧，结构简单，便于制作。
在一些实施例中，参阅图8，驱动板5还与显示面板12电连接，驱动板5还被配置为，响应于操作者指示显示影像的操作，驱动显示面板12显示；以及，向镜面切换屏2发送第二控制信号，以使镜面切换屏2透射显示面板12的显示画面。在这种情况下，用于驱动显示面板12显示的控制电路、以及用于驱动镜面切换屏2状态切换的控制电路均集成在同一驱动板5上，这样可以进一步地节省电路走线的布置空间，降低物料成本。
在此基础上，如图8所示，显示装置100还包括第二柔性电路板7，第二 柔性电路板7与显示面板12和驱动板5电连接。其中，通过弯折工艺将第二柔性电路板7弯折，可以使驱动板5位于显示面板12远离镜面切换屏2的一侧，以缩减显示面板12的边框。
需要说明的是，部分集成电路也可以设置在第二柔性电路板7上，例如，时序控制电路设置在第二柔性电路板7，本公开不限于此。此外，第二柔性电路板7远离显示面板12的端部设有第二连接部71，第二连接部71与驱动板5对应的接口电连接。
可以理解的是，如图1和图2所示，镜面切换屏2包括显示区B1和位于显示区B1的至少一侧的周边区B2，附图5以周边区B2包围显示区B1为例进行示意。
此处，显示区B1为镜面切换屏2的透光区域，显示区B1被配置为设置液晶层25中液晶分子。周边区B2可以被配置为布置镜面切换屏2所需的各种信号线以及封框胶251等。
其中，封框胶251的形状相对不规则，会大大影响视觉效果。基于此，为了提升视觉效果，如图1和图2所示，上述显示装置100还包括遮光层8，遮光层8设置于第二透明基板28远离显示面板1的一侧。
示例性地，如图2所示，遮光层8设置于第二透明基板28和第一吸收型偏光片29之间，第一吸收型偏光片29至少部分覆盖遮光层8，例如，第一吸收型偏光片29完全覆盖遮光层8。其中，遮光层8覆盖镜面切换屏2的周边区B2，以防止漏光。此外，遮光层8设置于第二透明基板28和第一吸收型偏光片29之间，不影响第一吸收型偏光片29远离显示面板12一侧的平整性，且遮光层8通过丝网印刷工艺形成在第二透明基板28远离显示面板12的表面，遮光层8与第二透明基板28之间的附着力更强，遮光层8不易脱落，可靠性更高。
示例性地，如图3所示，遮光层8和第一吸收型偏光片29均设置于第二透明基板28远离显示面板1的表面，遮光层8在参考面上的正投影与第一吸收型偏光片29在参考面上的正投影相互靠近的两边界近似重合，或遮光层8在参考面上的正投影与第一吸收型偏光片29在参考面上的正投影相互靠近的两边界之间具有间隙。其中，遮光层8覆盖镜面切换屏2的周边区B2，以防止漏光。
示例性地，如图4所示，遮光层8设置于第一吸收型偏光片29远离显示面板1的一侧。其中，遮光层8覆盖镜面切换屏2的周边区B2，以防止漏光。
这里，遮光层8可以通过丝网印刷工艺或溅射工艺形成在第二透明基板 28远离显示面板12的表面，以实现显示装置100的窄边框设计。遮光层8的材料包括油墨和/或金属。示例性地，遮光层8的材料为镜面银油墨或金属色油墨。以这种方式设置，在镜面切换屏2处于高反射状态下，采用镜面银油墨或金属色油墨均可以使得遮光层8与镜面切换屏2的显示区B1保持基本一致，镜面显示效果更佳。
例如，遮光层8的材料为挥发性干燥油墨。详细地，将高分子物质溶解于溶剂并印刷至第二透明基板28远离显示面板12的表面，形成墨膜；墨膜中的溶剂因蒸汽压的作用扩散在大气中，在墨膜表面形成液膜，然后通过液膜挥发。其中，在干燥的过程中，可以通过吹风加速干燥。这里，遮光层8的材料采用挥发性干燥油墨，工艺简单，生产速度快。
例如，遮光层8的材料为紫外光固化型油墨。详细地，将紫外光固化型油墨印刷至第二透明基板28远离显示面板12的表面；经过紫外线照射，紫外线油墨产生光化学反应，在几秒钟之内，即可完全固化。这里，紫外光固化型油墨的材料可以包括光聚合树脂、引发剂、色料及助剂。
又例如，遮光层8的材料为氧化干燥型油墨。详细地，将氧化干燥型油墨印刷至第二透明基板28远离显示面板12的表面；由于氧化干燥型油墨含有分子量较小的聚合物，在空气中氧化，通过热、光或反应性物质的化学反应而固化，形成高分子膜(遮光层8)。
在一些实施例中，上述遮光层8的厚度为6.5μm～7.5μm。这样，可以以在保证遮光的情况下，降低增加遮光层8对显示装置100整体厚度的影响。示例性地，上述遮光层8的厚度为6.5μm、7μm和7.5μm中的任一种。
在一些实施例中，参阅图1，遮光层8的最小宽度S2为4.3mm～4.7mm，遮光层8的最大宽度S1为8.89mm～9.29mm。示例性地，遮光层8的最小宽度S2为4.3mm、4.4mm、4.5mm、4.6mm和4.7mm中的任一者，遮光层8的最大宽度S1为8.89mm、8.99mm、9.09mm、9.19mm和9.29mm中的任一者。
需要说明的是，在限定宽度方向时，宽度方向根据遮光层8的所在位置不同而不同。示例性地，遮光层8在参考面上的正投影为条状，上述宽度方向指的是平行于参考面，且垂直于遮光层8的延伸方向的方向。例如，遮光层8可以由多段条状的子遮光图案相接形成如图1中所示的封闭环形，每个子遮光图案沿一个方向延伸，并对应镜面切换屏2的一个边界设置。此时。不同的子遮光图案的延伸方向不同，对应宽度方向也不同。
例如，显示装置100应用于汽车的后视镜10(参阅图10)，第一台阶280 对应位于显示装置100的下边界。显示装置100的下边界对应的遮光层8的宽度为8.89mm～9.29mm，显示装置100其余的边界对应的遮光层8的宽度为4.3mm～4.7mm。
可以理解的是，如图1和图9所示，上述遮光层8设有避让孔81，光敏传感器41在参考面的正投影，与避让孔81在参考面的正投影至少部分交叠，以保证光敏传感器41可以接收到外界的环境光。示例性地，光敏传感器41在参考面的正投影，位于避让孔81在参考面的正投影内，以避免遮光层8对第一光敏传感器41感测镜面切换屏2远离显示面板12的一侧的环境光的光线强度造成影响。其中，避让孔81的直径为2.5mm～2.9mm。例如，避让孔81的直径为2.5mm、2.6mm、2.7mm、2.8mm和2.9mm中的任一者。
在一些实施例中，参阅图1，沿第一方向X，显示装置100的最大尺寸L的范围为239.64mm～240.04mm。第一方向X与显示装置100的侧边大致平行。示例性地，沿第一方向X，显示装置100的最大尺寸L的范围为239.64mm、239.74mm、239.84mm、239.94mm和240.04mm中的任一者。
在一些实施例中，参阅图1，沿第二方向Y，显示装置100的最大尺寸W的范围为61.2mm～61.6mm。第二方向Y与第一方向X大致垂直。示例性地，沿第二方向Y，显示装置100的最大尺寸W的范围为61.2mm、61.3mm、61.4mm、61.5mm和61.6mm中的任一者。
例如，参阅图1和图10，显示装置100应用于汽车的后视镜10，后视镜10的外轮廓大致为梯形，显示装置100下边界的尺寸大于上边界的尺寸，第一方向X与显示装置100的下边界大致平行。此时，沿第一方向X，显示装置100的尺寸L为239.84mm，沿第二方向Y，显示装置100的尺寸W为61.4mm。
需要说明的是，“大致为梯形”是指，后视镜10的外轮廓的形状整体上呈梯形形状，但是并不局限为标准的梯形。即，这里的“梯形”不但包括基本梯形的形状，而且考虑到工艺条件，还包括类似于梯形的形状。例如，梯形的拐角处为弯曲状，即拐角处平滑，使得后视镜10的外轮廓在平面图的形状为圆角梯形。
本公开的一些实施例还提供一种显示装置，该显示装置包括显示面板、第一光敏传感器、第一电路板和驱动板。
这里，显示面板的出光侧能够在高透射状态和高反射状态之间切换。其中，当显示面板的出光侧处于高透射状态下，显示画面可以透射出显示面板，实现显示功能；当显示面板的出光侧处于高反射状态下，外界的光由显示面板反射呈现镜像。
需要说明的是，本公开实施例所提供的显示装置的显示面板可以包括上述实施例所述的显示装置100的显示面板12和镜面切换屏2，具体特征、结构可以参考上文，本公开在此不做赘述。
其中，第一电路板包括绑定部、元器件部和走线部，第一光敏传感器设置于元器件部，走线部设有与绑定部的绑定焊盘和第一光敏传感器电连接的走线。驱动板通过第一电路板的走线部与显示面板电连接。
需要说明的是，本公开实施例所提供的显示装置的第一电路板可以包括上述实施例所述的显示装置100的第一柔性电路板6，具体特征、结构可以参考上文，本公开在此不做赘述。此外，本公开实施例所提供的显示装置的驱动板可以包括上述实施例所述的显示装置100的驱动板5，具体特征、结构可以参考上文，本公开在此不做赘述。

如图8和图10所示，本公开的一些实施例还提供一种后视镜10，该后视镜10包括上述任一实施例所述的显示装置100。
以上所述，仅为本公开的具体实施方式，但本公开的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本公开揭露的技术范围内，想到变化或替换，都应涵盖在本公开的保护范围之内。因此，本公开的保护范围应以所述权利要求的保护范围为准。
