Head-up display and control method thereof

The invention provides a head-up display and a control method thereof, and relates to the technical field of image display. According to the specific implementation scheme, the head-up display comprises a shell, a reflecting mirror, an image generation unit and a driving part, wherein the reflecting mirror is arranged in the shell; the image generation unit is arranged in the shell and comprises a body and a display screen which are connected with each other, and an image output by the display screen forms a virtual image seen by a user on a windshield of the vehicle through a light path between the image generation unit and the reflector; the driving part is connected with the image generation unit and used for driving the image generation unit to move. According to the scheme, the pose of the focal plane of the virtual image can be changed. 本公开提供了抬头显示器及其控制方法，涉及图像显示技术领域。具体实现方案为：抬头显示器包括壳体、反射镜、图像生成单元和驱动部，反射镜设置于壳体内；图像生成单元设置于壳体内，包括相互连接的本体和显示屏，显示屏输出的图像通过图像生成单元与反射镜之间的光路，形成用户在车辆风挡玻璃上所视的虚像；驱动部与图像生成单元连接，用于驱动图像生成单元运动。
