Abstract

The invention provides a head-up display device, a control method thereof and a vehicle. The head-up display device comprises a display component, a first optical component, a second optical componentand a composite component. The first optical component transmits or reflects light in different polarization directions or polarization states to realize light separation of state information projection and augmented reality information projection, and two-layer display is realized. For example, augmented reality information can be displayed at a distance far from the eyes of a driver. The focallength of the human eyes is not adjusted frequently during a driving process, which makes viewing more comfortable and eliminates safety hazards.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a head-up display device, a control method thereof, and a vehicle. Background technique [0002] Head up display (head up display, HUD), also known as head-up display, has gradually been widely used in the automotive field. The head-up display projects the important information displayed on the instrument (such as vehicle speed), navigation and other information on the front windshield glass during the driving process of the car, so that the driver can see the information in the instrument without looking down. This can not only help novices who are inexperienced in speed judgment to control their speed, but more importantly, it can enable the driver to read instantly without shifting the large field of vision, preventing the driver from looking down at the instrument display or watching the audio display. It is too late to take effective measures in case of emergency. [0003...
