Description

Technical Field

[0001] The present invention relates to the technical field of display enhancement, and in particular to a vehicle-mounted holographic projection system with enhanced display. Background Art

[0002] With the development of technology, most cars are equipped with in-car navigation and driving computers, which greatly facilitate the travel of car owners. However, in actual application, for safety reasons, many drivers dare not pay too much attention to the navigation screen and the car dashboard. When using in-car navigation, most drivers will only concentrate on listening to the voice navigation instructions of the machine, which may cause them to take the wrong road due to missing a voice instruction or different semantic understanding, which may lead to taking the wrong road.

[0003] At the same time, many drivers tend to look down at the dashboard or multimedia screen too much during driving, which can lead to traffic accidents. To solve this problem, head-up displays (also known as HUDs) have emerged. Head-up displays mean that drivers can see the important information they need without looking down. Head-up displays can reduce the frequency of drivers looking down at the dashboard and screen, avoiding accidents caused by frequent diversion of attention.

[0004] However, during the use of the current in-vehicle holographic projection system, since the driver needs to turn on the air conditioner in winter and in summer while driving to ensure the internal temperature of the vehicle, it will cause a large temperature difference between the inside and outside of the vehicle, causing the window to deform, thus affecting the projection quality, and easily causing ghosting and excessive projection brightness affecting the driver's vision.
