Problems solved by technology
Due to the different height of each driver and the fact that more and more cars are equipped with multiple HUDs with different display distances or functions, the middle bonding layer pair with a single wedge angle value weakens the projection onto the front windshield. The secondary image does not work well, resulting in a poor quality HUD image projected onto the windshield

Abstract
The invention provides a head-up display system and a design method of the head-up display system. The head-up display system comprises laminated glass and a projection assembly. The laminated glass comprises a first transparent substrate, a second transparent substrate and a middle bonding layer, wherein the middle bonding layer is used for bonding the first transparent substrate and the second transparent substrate; the laminated glass is provided with a plurality of projection display areas, and each projection display area is provided with a wedge-shaped section shape that the thickness of the upper side edge is larger than that of the lower side edge when the laminated glass is installed on a vehicle. Wherein the plurality of projection display areas comprise at least one first projection display area; the projection assembly comprises at least one projection light source capable of projecting to the plurality of projection display areas, the projection light source enters the first projection display area to form a first projection image, and the virtual image distance of the first projection image is 7-100 m. The head-up display system provided by the invention can improve the quality of the head-up display image.
Description
technical field [0001] The present application relates to the field of automobiles, and in particular, to a head-up display system and a design method of the head-up display system. Background technique [0002] With the development of automobile intelligence, more and more Head Up Display (HUD) systems are used in automobiles, and images, such as driving information, are displayed in front of the front windshield in real time through the HUD system. The front windshield is usually laminated glass, and an intermediate adhesive layer with a wedge angle is required to eliminate the secondary image projected onto the front windshield. Due to the different height of each driver and the increasing number of HUDs with different display distances or functions on more and more cars, the intermediate bonding layer with a single wedge angle value weakens the projection of the front windshield. The effect of the secondary image is not good, resulting in a poor quality head-up display ...
