    An automotive head-up-display (HUD) can display information exactly in the sight of a driver. Drivers get all the important information such as speed, warning signals and indicator arrows for navigation without looking down to the instrument cluster or the secondary display. So HUD can lengthen the time of the drivers spending on viewing the road situation for safer driving and reduce the eye strain for more comfortable driving. For next generation HUD, it is expected the virtual image can cover the full windshield and be adjustable at different distances. While traditional HUD technologies have limitations to realize this kind of HUD, such as high power consumption, bulky packaging size, and non-possibility to provide virtual image at variable distance, holographic projection display shows great potential for next generation HUD due to its ultra high efficiency and capability for adjusting the virtual image distance. In this project, we are going to develop high efficient holographic HUD (HHUD) with large field-of-view (FOV) and compact volume for next generation automotive application. We will use sub-pixelated liquid-crystal-on-silicon (LCoS) phase modulator, which will be realized by stabilized multi-domain photo-alignment process, to increase the holographic HUD’s FOV. And we will use reflective total-internal-reflection (R-TIR) type projection engine and waveguide type optical system design to reduce the holographic HUD’s volume. The technology yielded from this project will be implanted in automotive HUD and other see-through displays, which can be widely applied in automotives, aviation, education, medical, manufacturing and other industries. The global head-up display market is estimated to worth 9.02 billion USD by 2020. The project is committed to advance the development of Hong Kong and the Pearl River Delta to become the R&D center of automotive HUD products and technologies, and the manufacturing center of automotive core components. Furthermore, this project will benefit local industries and bolster industrial upgrading.
