Head-up display system and vehicle

Abstract

The embodiment of the invention discloses a head-up display system and a vehicle. The head-up display system comprises a control module, an image source module and an imaging module, the image source module comprises a display assembly and a dimming assembly, and the dimming assembly comprises a polarization state adjusting unit, a metal wire grating and a reflector which are sequentially arranged along the side away from the light emitting surface of the display assembly; the display assembly is electrically connected with the control module, and the display assembly is used for emitting imaging light under the control of the control module; and the polarization state adjusting unit is electrically connected with the control module, and the polarization state adjusting unit is used for modulating the imaging light into polarized light in the first polarization direction within the first display time period t1. In the second display time period t2, modulating the imaging light into polarized light in the second polarization direction. The imaging module is used for transmitting the polarized light in the first polarization direction or the polarized light in the second polarization direction to a windshield, and the windshield reflects the polarized light into human eyes for imaging. According to the embodiment of the invention, the size and cost of the head-up display system are reduced.

Description

technical field [0001] Embodiments of the present invention relate to head-up display technology, in particular to a head-up display system and a vehicle. Background technique [0002] Head Up Display (HUD) has gradually been widely used in the automotive field. The head-up display is to project the important information (such as vehicle speed, navigation, etc.) displayed on the instrument during the driving of the car onto the front windshield, so that the driver can see the information in the instrument without looking down, which can not only help the lack of speed judgment Experienced novices can control their speed to avoid violating regulations due to speeding on speed-limited roads. More importantly, it can enable the driver to read instantly without shifting the large field of view, and always maintain the best observation state. [0003] The existing head-up display system can present a double-layer virtual image, and the virtual image that the user can see is a tw...
