Example 1

As shown in fig. 1 and 2: in the present embodiment, the HUD applied to the automobile is used to display 2 images, and it is assumed that A, B are displayed for each of the two images.

Firstly, a projector 1 is installed, then a reflection wheel 2 is installed, a reflecting mirror 3 is installed, and the reflection wheel 2 is installed between the projector 1 and the reflecting mirror 3. Then the reflective wheel 2 (see fig. 2) is divided into 6 parts, wherein three parts are made of reflective mirror materials and are blank parts or hollow parts through which images can pass. These projector 1, reflection wheel 2 and mirror 3 are located below the windshield 4. The reflective wheel 2 is then connected to a motor driven by the motor.

When playing the image, the projector displays (A B) ^ n two groups of images in sequence according to time sequence, the reflective wheel rotates according to a certain frequency, the projector plays AB picture with YHz, and the reflective wheel rotates. When the projector displays an image A, the mirror part of the reflection wheel is positioned in the light path, the image A is reflected to the position A of the windshield and then reflected to human eyes, a virtual image A 'is formed outside the windshield, when the projector displays an image B, the blank part of the reflection wheel is positioned in the light path, light rays penetrate through the reflection wheel to irradiate the reflection mirror, the image B is reflected to the position B of the windshield and then reflected to the human eyes, and a virtual image B' is formed outside the windshield. Thus, a dual-screen display effect is achieved.

Example 2

As shown in fig. 2, 3, and 4, in the present embodiment, 3 images are displayed on the HUD applied to the automobile as an example, and first, it is assumed that A, B, C are displayed for each of the two images.
