Description:

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 will do a feasibility study of thermal stability of liquid crystal on silicon (LCoS) phase modulator for next generation automotive holographic HUD application. We will develop surface stabilized photo-alignment process by surface polymerization to increase the thermal stability. The technology developed in this project can be used for LCoS phase modulator as well as conventional LCoS panel, which can be widely applied in automotives, aviation, education, medical, manufacturing and other industries.
