AR-HUD as one of the core configurations of the intelligent networked car of ADAS information display can combine virtual icons with road reality to achieve AR real scene navigation, compared with the traditional instrument + large screen solution, AR HUD can interact with the road environment, intuitive and timely display information, is the development direction of intelligent cockpit.

      Laser Scanning Projection (LBS) technology, known as Laser Beam Scanning, is a "MEMS micro laser projection" scheme. Due to the use of laser light source, it has the advantages of wide color gamut, large brightness and high contrast display. In addition, this technical solution can also achieve a large field of view FOV, while the structure is simple, the size is small, and it has a good application scenario in AR HUD.

      The director of this summit introduced the PGU module scheme of the vehicle AR-HUD LBS and shared how to optimize the disadvantages of the LBS laser solution such as backlight, speckle problem, and sunlight back irrigation. In addition, according to reports, the current on-board application of LBS technology is expected to advance rapidly: laser chips and modules are passing the car rules as soon as possible, and they also have their own advantages in terms of cost and safety.
