This invention provides a novel light field AR-HUD device integrating dual-focal-plane and triple-focal-plane displays. In this invention, light from three different virtual image distances is emitted from the same image source. The light from the farthest focal plane passes through an adjustable optical path device and is transmitted together with the light from the intermediate focal plane to a small freeform surface mirror. The light from the closest focal plane is emitted by the PGU and transmitted to the small freeform surface mirror. Then, the light from all three focal planes is projected onto a large freeform surface mirror and reflected by the car windshield into the driver's eyes, allowing the driver to simultaneously see images from three different distances. This invention uses a single PGU and, through its optical structure, can achieve switching between dual-focal-plane and triple-focal-plane light field AR-HUD displays, meeting the needs of more driving scenarios, resulting in more layered images and superior display effects, while avoiding a significant increase in cost, providing a new solution for the development of HUD technology.

This utility model provides an indoor unit for an air conditioner, including a housing and a voice module. The housing has a support frame and a decorative panel disposed on the front side of the support frame. The decorative panel has a voice through hole, and the support frame has a clearance space corresponding to the position of the voice through hole. Because the sound receiving hole or sound output hole of the voice module is correspondingly arranged with the voice through hole, and the voice module is fixedly mounted on the decorative panel, and the clearance space is provided within the support frame, the voice module is located within the clearance space. Therefore, the voice module will move synchronously with the decorative panel and will not be blocked by the support frame.
