应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步定义和解释。
下面结合附图，对本申请的一些实施方式作详细说明。在不冲突的情况下，下述的实施例及实施例中的特征可以相互组合。
现有技术中，平视显示器只有半透半反层，在强烈的阳光下，人眼无法看清楚平视显示器HUD反射过来的图像。驾驶员通过平视显示器HUD的半透半反层看到两个图像，一个是镜片反射的平视显示器HUD光源屏幕图像，一个是通过HUD半透半反层和汽车前档玻璃看到的前车窗外车前方道路上的图像。同一个区域看到两个图像，哪一个亮度高，则哪一个看得清晰。如果两个亮度都基本一样，则人眼焦距决定哪个图像可以看得清晰。如果一个图像亮度很低，另外一个图像亮度很高，则亮度低的一个图像，彻底无法被看清。
因为传统HUD的光源屏幕的亮度虽然很高，但是远远无法跟车窗外的阳光亮度相比。一般HUD的光源屏亮度大约1万cd/m 2左右，光线被HUD反射镜片反射后，驾驶员看到的亮度大约是几千cd/m 2。而白天汽车车窗外的光线大约是1万到30万cd/m 2，驾驶员眼睛穿过平视显示器的半透半反射镜片，在平视显示器上看到的车外道路亮度仍然为数万cd/m 2，远远高于平视显示器显示图像亮度。所以驾驶员在强烈的阳光下，根本无法看清楚平视显示器上的图像。
请参阅图1，图1为本申请实施例所提供的一种平视显示器100的结构示意图。
请结合参阅图2，图2为图1中区域A的结构示意图。本申请实施例中，所述平视显示器100包括显示屏幕，所述显示屏幕包括有半透半反层110和变色层120，所述半透半反层110与所述变色层120层叠设置。在白天强光的照射下可变色层120变化为暗色，大大削弱了车外光，导致透光率降低，从而实现平视显示器100的图像被驾驶员清晰地看到。
可选地，所述平视显示器100中的变色层120可以为电致变色材料，也可以为光致变色材料。电致变色材料需要配合光感和IC使用。光致变色材料在遇到强光时由于材料自身的特性，改变其透射率。因此，所述变色层120在遇到强光时，可以降低其透射率，使得平视显示器100在强光下显示效果仍然很好。
请结合参阅图3至图7，本申请实施例中，所述平视显示器100中的变色层120为变色镜121，所述半透半反层110为半透半反镜111。变色镜121部分，可以在阳光照射下导致变色，也可是对变色镜121片进行通电导致其变色。
可选地，所述变色层120为变色油漆122，所述半透半反层110为半透半反膜112与玻璃镜130组成。所述变色油漆122可以在阳光照射下导致变色，也可以对其通电导致其变色。
可选地，所述变色层120为变色镜121，所述半透半反层110为半透半反膜112。所述变色镜121可以在阳光照射下导致变色，也可以对其通电导致其变色。
可选地，所述变色层120为变色镜121，所述半透半反层110为半透半反膜112与玻璃镜130组成。所述变色镜121可以在阳光照射下导致变色，也可以对其通电导致其变色。
可选地，所述变色层120为变色膜，所述半透半反层110为半透半反膜112与玻璃镜130组成。所述变色膜可以在阳光照射下导致变色，也可以对其通电导致其变色。
可选地，所述半透半反层110与所述变色层120通过胶水贴和镀膜的方式进行层叠设置。
可选地，所述变色层120为胶体层123，所述半透半反层110为半透半反镜111与玻璃镜130，所述胶体层123设置于所述半透半反镜111与玻璃镜130之间。其中，胶体层123为电致变色胶体，不通电时透明，通电时颜色变深，透射率降低。胶体层123周围有封胶防止电致变色胶体流出来。半透半反镜只有在远离胶体一侧有反射镀层，靠近胶体的一侧没有反射作用。
本申请实施例中，夜间、傍晚和清晨，车前光线弱时，电路不给电致变色胶体通电，镜片透明。
白天车外有很强的光线强度，电路自动调节镜片透光率，以达到既保证镜片有一定的透光率，又可降低车前物体在透过镜片后的亮度，保证驾驶员可看清显示屏和透过镜片看到车前物体。
假设车前有一物体为A，有太阳时，物体A亮度远高于显示屏图像，工作时光电传感器给电致变色胶体通电，则镜片透光率变得很低，所以驾驶员看到的车前A物体亮度大大降低，而镜片的反射率未变化，显示屏反射亮度还是以前的亮度。这样驾驶员就可以看清车前方的场景。

综上所述，本申请实施例提供一种平视显示器及平视显示装置，所述平视显示器应用于车辆上，所述平视显示装置包括有支架部和平视显示器，所述平视显示器包括显示屏幕，所述显示屏幕包括半透半反层和变色层，所述半透半反层与所述变色层层叠设置，所述变色层在强光照射下可降低透光率。以使用户在强光的照射下依旧能看清平视显示器反射的图像，提高平视显示器的实用性。
车外光线，在透过HUD反光镜片(半透半反射)区域，进入驾驶员眼睛的时候，因为变色层，从高透明变化为暗色时导致透光率降低，大大削弱了车外光，导致车外光亮度大大降低，从而实现了平视显示器HUD屏幕的画面图像被驾驶员清晰地看到。
解决了白天车外强光对平视显示器HUD显示的干扰问题。虽然平视显示器HUD反光镜片因为变色镜片的变色，而导致透光率大大降低，但是因为车外光线非常强，所以仍然会有足够的光线进入驾驶员眼睛，使得其可以看到车前道路。
同时，在夜间、清晨或黄昏，当道路上光线较弱的时候，变色镜片会自动恢复为高透明状态，确保驾驶员可以透过镜片看到车前道路。
