Abstract
A head-up display system includes a housing, a liquid crystal display disposed within the housing and configured for emitting a first ray of light, and a reflector stack disposed adjacent the liquid crystal display within the housing. The reflector stack is configured for transmitting therethrough the first ray of light and includes a retardation plate and an optical film disposed on the retardation plate and facing the liquid crystal display. The head-up display system also includes a radiative heat sink disposed on the housing and a turn mirror spaced apart from the reflector stack. The turn mirror is configured for directing a first solar ray to the reflector stack such that the first solar ray reflects off the reflector stack to the radiative heat sink as a second solar ray.
