HUD trends
From the early reflective HUD, then Combiner Type HUD, Windshield Type HUD, to AR HUD, with the update of automotive electronic technology, HUD applications in automobiles are becoming more and more common. Compared with the Combiner Type HUD and the reflective HUD, the Windshield Type HUD can not only be hidden in the car body, but the virtual image of the displayed image is several meters in front of the driver, which perfectly integrates the vision of the car. In order to meet the longer projection distance and wider projection image, finally based on the characteristics of Windshield Type HUD, a more powerful AR HUD is extended.
AR HUD technical problems
AR HUD also has its technical problems. First, the AR HUD needs to be buried in front of the dashboard, but the wide projection of the AR HUD requires a large-size panel, which makes the AR HUD larger in size and not directly applicable to every car model.The configuration of automobile parts requires special design; the imaging principle of AR HUD, if it is directly applied to a general automobile windshield, it will cause ghost image, which is commonly known, so the windshield needs to use wedge glass, which increases the cost. The above two points have caused an increase in the time and money cost of AR HUD development, and it is not easy to introduce. At the same time, AR HUD has high power consumption due to large panel, which in turn leads to high product operating temperatures and increases heat dissipation problems.
The introduction of MAVE technology into AR HUD will solve the technical problems of AR HUD, but the introduction of MAVE and mass production are difficult, and UniMax has become a rare company in the world with this technical capability.
Flat type AR HUD(MAVE)
UniMax HUD series products have excellent internal light path design, both low power consumption and low heat dissipation. The optical design of AR HUD has successfully introduced advanced MAVE technology, so that the external light path can be imaged by penetration and reflection, such as blinds, Can project wide images without a large panel. From the perspective of the light guide structure in the external light path, the brightness efficiency of other brands using Hologram technology is about 1%, while the brightness efficiency of MAVE used by UniMax can reach at least 8%, and even up to 30%. Become the only industry leader that can introduce this technology and mass production at present.
Thanks to the MAVE imaging technology, the AR HUD can be reduced in size by at least 30%, and can be easily embedded in the interior space in front of the dashboard, and is suitable for most cars on the market; imaging in the general windshield will not cause ghosting problems. Special wedge-shaped glass is required, which is easier to import and cost-saving. Coupled with the high-efficiency and low-power image generation unit (PGU), common technical problems can be solved at once.
