Abstract
A head-up display system and a display apparatus are provided in this disclosure, which relates to a technical field of displaying. The head-up display system includes a display unit; a light splitting unit provided on a light emitting side of the display unit and configured to transmit a first linearly polarized light and block a second linearly polarized light, light emitted by the display unit being converted into the first linearly polarized light after passing through the light splitting unit; a light-transmitting substrate; a first imaging unit provided on an optical path from the light splitting unit to the light-transmitting substrate and configured to be able to transmit and reflect the first linearly polarized light; and a second imaging unit provided on a side of the light-transmitting substrate away from the first imaging unit, and configured to reflect the first linearly polarized light transmitted through the light-transmitting substrate.
