Problems solved by technology
[0003] However, the field of view (FOV, Field of View) of the traditional HUD based on the free-form surface mirror is often very small, generally within 10 degrees, which leads to a small display size of the HUD image, and generally can only display vehicle speed or direction information. It is impossible to display richer content, such as navigation maps and complex safety information. The dimension and density of information presentation are low, which makes it difficult for drivers to receive and control various information during vehicle driving; to increase the display size, it is necessary to increase the The size of the HUD will greatly increase its power consumption, resulting in limited HUD display effect, unable to expand more applications, and limiting the further promotion and application of HUD

The invention provides head-up display equipment based on environment display. The head-up display equipment comprises an imaging device and a processor, wherein the imaging device is arranged on one side of a reflection imaging layer, and the imaging device comprises a backlight source part, a main optical axis adjusting component, a light beam expanding component and a liquid crystal panel; and the processor is used for obtaining external environment information, determining key information needing to be displayed currently according to the external environment information and controlling the imaging device to display the key information. According to the head-up display equipment based on environment display provided by the embodiment of the invention, the main optical axis adjusting component can converge the imaging light with different incident angles into the same preset area and diffuse the imaging light into the range of an eye box, so that the imaging brightness can be improved, and the imaging range can be ensured; and the imaging device can be arranged in a large range, so that a large-area directional imaging area is formed on the surface of the reflection imaging layer, large-range imaging is achieved, and the display effect of the reflection imaging layer can be improved.
Description
technical field [0001] The present invention relates to the technical field of safe driving, in particular to a head-up display device based on environment display. Background technique [0002] HUD (head up display, head up display) technology can avoid the driver's distraction caused by looking down at the dashboard during driving, which can improve driving safety and bring a better driving experience. Therefore, HUDs that use car windshields for imaging are receiving increasing attention. [0003] However, the field of view (FOV, Field of View) of the traditional HUD based on the free-form surface mirror is often very small, generally within 10 degrees, which leads to a small display size of the HUD image, and generally can only display vehicle speed or direction information. It is impossible to display richer content, such as navigation maps and complex safety information. The dimension and density of information presentation are low, which makes it difficult for driver...
