Problems solved by technology

[0005] There are two main problems in the above two schemes: 1. High cost: a complex optical system is required, which leads to high cost, especially scheme 1; 2: Display brightness is affected by ambient light: because transparent display schemes are used in the schemes, When the external ambient light is strong, it is almost difficult for human eyes to observe the displayed image

Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0021] A vehicle-mounted head-up display system, combined with image 3 , Figure 4 As shown, it includes a housing 1 with an opening on one side and a prism 2 and a display screen 3 installed inside the housing. The display screen 3 is installed on one side of the first surface 4 of the prism 2 in parallel. A virtual image 7 is formed on the side of the second surface 5 of the prism 2 , and the virtual image 7 can be observed by human eyes on the side of the thir...

Abstract

The invention provides a vehicle-mounted head-up display system. The system comprises a shell, one side of the shell is open, and the prism and the display screen are installed in the shell. The display screen is installed on one side of the first surface of the triangular prism in parallel, a picture of the display screen forms a virtual image on one side of the second surface of the triangular prism after being refracted by the triangular prism, the virtual image can be observed when human eyes are located on one side of the third surface of the triangular prism, and the opening of the shellcorresponds to the third surface of the triangular prism. The triple prism and the display screen are matched for imaging, the structure is simple, and the cost is low. In the technical scheme of theinvention, the formed virtual image has a very high contrast ratio in a dark environment, is not easily influenced by ambient light, and is clear in display.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted optical displays, in particular to a vehicle-mounted head-up display system. Background technique [0002] In traditional automobiles, some instrumentation information such as vehicle speed, temperature, and fuel level are generally displayed on the dashboard, while the dashboard of a car is generally located far below the driver's line of sight, which is not conducive to the driver's observation, and during the observation process In the middle of the road, the eyes of the driver will leave the road, which increases the risk of driving. In this case, the vehicle-mounted head-up display came into being. The vehicle-mounted head-up display can display instrumentation information directly in front of the driver or slightly below the driver's line of sight through physical optics, so that the driver's line of sight does not need to leave the road. You can understand the purpose of the releva...
