本实施例提供的显示装置，将显示屏300设置在壳体100内，在显示屏300发出的光线的传播路径上设置有第一导光件400，光偏转件将特定方向的光线遮挡，使得显示屏300 显示出来的图像信息仅能够供驾驶室位置的驾驶员观察。在匪情发生时，将显示屏300显示的信息传输给警方，警方通过驾驶员传输的信息可以有效判断现场情况，并指示驾驶员进行相应操作，警方指示驾驶员的操作显示在显示屏300上，而由于显示屏300的位置以及传播光线的设置，使得驾驶员能够清楚知道显示屏300上的信息，匪徒却不易察觉，这样的结构设计，大大提高了驾驶员的安全性，也利于协助警方控制匪徒。
请参阅图5和图7，本实施例中，可选的，壳体100包括有前壳110、后壳120、第一安装件130、第二安装件150以及硅胶垫140。前壳110为具有安装开口111的环形结构，安装开口111大致呈矩形开口，与后视镜玻璃200的形状匹配。后壳120为弧形壳，后壳120为一端敞口的槽结构，后壳120的敞口所在一侧与前壳110通过卡扣结构扣合连接。例如，前壳110沿其安装开口111的轴线方向具有第一安装侧和第二安装侧，前壳110的第二安装侧上设置有至少两个卡接槽113，至少两个卡接槽113围绕前壳110的周向间隔排布，在后壳120的敞口所在一侧的内壁上设置有至少两个卡接凸起121，至少两个卡接凸起121围绕后壳120的周向间隔排布，前壳110的第二安装侧对准后壳120的敞口，两者相互靠近运动，使至少两个卡接槽113与至少两个卡接凸起121一一对应卡接，实现前壳110和后壳120的安装。在前壳110的第一安装侧具有内翻的遮挡环112，遮挡环112与后壳120的敞口所在一侧具有间隙，将后视镜玻璃200卡接在间隙中，依靠遮挡环112进行限位，防止后视镜玻璃200从第一安装侧处滑出。前壳110和后壳120扣合时，硅胶垫140位于前壳110和后壳120之间，硅胶垫140可以为柱形，硅胶垫140的一端卡接在后壳120的内壁上，硅胶垫140的另一端抵接在后视镜玻璃200上，后视镜不易振动损坏。进一步的，硅胶垫140的一端具有“十字”卡槽，在后壳120的内壁上具有“十字”凸起，硅胶垫140通过卡槽卡接在凸起外。
需要说明的是，硅胶垫140的数量按需设置，本实施例中，硅胶垫140设置有两个，两个硅胶垫140分别位于壳体100长度方向的两侧。其它实施例中，硅胶垫140也可以设置三个或者四个。
请参阅图6和图7，可选的，第一安装件130包括第一安装板131以及第二安装板132，第一安装板131和第二安装板132相对设置，第一安装板131大致为U形板。具体的，第一安装板131具有呈矩形状的第一直板部1311和呈矩形状的第一折弯板部，第一折弯部1312为两个，两个第一折弯板部安装在第一直板部1311的两侧，第一直板部1311的一侧和两个第一折弯板部的一侧均安装在后壳120上，第一直板部1311远离后壳120的一侧设置有第一卡槽1313，第一卡槽1313的截面形状为L形，第一折弯部1312板远离后壳120的一侧设置有第二卡槽1314，第二卡槽1314的截面形状为L形，两条第二卡槽1314与第一卡槽1313连通。第二安装板132大致为U形板，第二安装板132包括矩形状的第二直板 部1321和矩形状的第二折弯板部，第二折弯部1322为两个，两个第二折弯部1322安装在第二直板部1321的两侧，第二直板部1321一侧与两个第二折弯部1322的一侧安装在后壳120上，第一折弯部1312与对应的第二折弯部1322间隔设置形成条形的缺口134，第一安装板131和第二安装板132之间具有两条缺口134，第二折弯部1322远离后壳120的一侧设置有第三卡槽1323，第三卡槽1323的截面形状为L形，第一卡槽1313、第三卡槽1323以及两条第二卡槽1314构成卡口133。

需要说明的是，显示屏300采用现有技术即可，本实施例中未对其结构和功能进行改进，为了避免叙述重复累赘，对于显示屏300的结构和原理不进行详细说明。
本实施例中，可选的，显示屏300可以是矩形板状，能够显示的图像信息更加全面，便于观察。显示屏300卡接在第一安装件130上的卡口133内。由于第一安装件130具有缺口134，便于显示屏300的拆卸与维修。
请参阅图8，本实施例中，第一导光件400可以是中空的柱形结构，采用不透光材料制成。第一导光件400可以是导光筒，导光筒为矩形筒状，即第一导光筒的垂直于其轴线方向的截面形状为矩形环，导光筒的两端分别为第一导光口420和第二导光口430，第一导光口420所在一端插接在卡口133中，第一导光件400罩住显示屏300，第一导光口420的形状与显示屏300的形状匹配，显示屏300传播出来的光线可以完全从第一导光口420进入到第一导光通道410中，不易丢失图像，然后从第二导光口430传播出来，第一导光件400的第二导光口430所在端面贴合在后视镜玻璃200的半透区域上，第一导光件400的遮挡效果更好，不易被除驾驶员以外的人看到显示屏300上显示的信息，驾驶员通过后视镜玻璃200接收到从第二导光口430传播出来的光线，进而观察到显示屏300显示的信息。第二导光口430所在端面与第一导光口420所在端面倾斜设置，便于第二导光口430贴合在后视镜玻璃200上。其中，后视镜玻璃200的半透区域是指，外部光线可以进到后视镜内部，后视镜内部光线也可以射出，即可以看到屏幕内容。在后视镜玻璃的半透区域以外的区域一般进行镀银处理，不易透光，便于利用后视镜观察后方情况。驾驶员从半透区域观看到显示屏上显示的影像。
本实施例中，可选的，显示屏300发出的光线通过第一导光件400后，只有特定方向的光线传播到后视镜玻璃200上被驾驶员看到。为了更加清楚描述仅供驾驶员看到的后视镜玻璃200上的显示位置，设定，后视镜玻璃200具有沿其长度方向的第一侧210和第二侧220以及沿其宽度方向的第三侧230和第四侧240，第一侧210、第三侧230、第二侧220 和第四侧240依次首尾连接，后视镜安装完毕后，第一侧210为驾驶员的左侧，第二侧220为驾驶员的右侧，第三侧230为车顶所在一侧，第四侧240为车底所在一侧。显示屏上显示的影像为显示影像，后视镜玻璃上的影像为视觉影像，视觉影像相对于显示影像由第三侧230向第四侧240的方向偏转，即显示屏300显示的影像在驾驶员的位置仰视才能够看到。
或者，在其他实施例中，视觉影像相对于显示影像由第三侧230向第四侧240的方向偏转以及由第二侧220向第一侧210的方向偏转，即显示屏300显示的影像在驾驶员位置视线朝向右上方才能够看到。显示屏300的隐蔽性更高，不易被车内除驾驶位置的其他人员发现，防匪效果好。
需要说明的是，视觉影像并不是表示在后视镜玻璃上成像，而是指通过后视镜玻璃上的可视区域(半透区域)能够观察到显示屏上显示的影像，利用视觉影像的位置表示可视区域的位置。
需要说明的是，后视镜玻璃200的材质按需选择即可，同时，显示屏300的尺寸根据不同后视镜的尺寸进行相应调整。

需要说明的是，显示装置工作时，表示摄像头600能够采集图像信息且传输至控制器进行储存，而显示屏300可以处于关闭状态。显示屏300处于关闭状态时，驾驶员利用后视镜玻璃观察后方情况时更加方便，投射在后视镜玻璃中的内容更加清晰。
