Description

一种具有显示仪表功能的后视镜及其控制系统
本申请要求于2018年02月06日提交中国专利局，申请号为CN 201810122117.5，发明名称为“一种具有显示仪表功能的后视镜及其控制系统”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及汽车零部件技术领域，尤其是涉及一种具有显示仪表功能的后视镜及其控制系统。
背景技术
现有的汽车为了让驾驶员知道车速、转速、油量等状况，常常要将各个参数显示在仪表盘上。
现有的仪表盘位置在驾驶员正前方偏下，观看时需要将视线拉回来看，有时还会因为方向盘遮挡，导致看不清。不利于行车安全和对车辆状况的了解。
传统的汽车内后视镜，采用将小型的LED屏，或VFD等屏幕嵌入内后视镜中，这种屏幕显示面积小，而且显示的内容无法到达后视镜的边缘，显示效果不绚丽。所以目前极少有采用这种方法。
另外一些传统后视镜，内嵌TFT液晶屏，这种屏因为价格贵，而且因为液晶屏边缘都一定宽度的非工作区域，所以显示的内容无法到达后视镜最边缘处，视觉上不美观。
还有一些后视镜，在前壳LED屏四周边缘密布LED字符，用以表达车速和转速等信息，但是，通常情况下，LED字符距离前壳边缘较远，显示区域过小。
