Abstract

The invention discloses a vehicle-mounted imaging display system and a method for eliminating real image ghosting. The vehicle-mounted imaging display system comprises a display device which is used for emitting an imaging light beam; the reflector is used for reflecting the imaging light beam to obtain a reflected light beam; the imaging assembly is used for processing the reflected light beam to obtain an emergent light beam; wherein after the emergent light beam is reflected by a front windshield of the vehicle, an aerial real image is formed in an aerial preset area in the vehicle. According to the vehicle-mounted imaging display system, the aerial imaging technology can be used for vehicle-mounted display.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted display, in particular to a vehicle-mounted imaging display system and a method for eliminating real image ghosting. Background technique [0002] In the field of in-vehicle display, image ghosting is generally generated when the front windshield is used for imaging, and most of the existing head-up display systems on the market that require front windshield imaging are used. Head-up display systems were originally used as flight aids on aircraft. Now, with the development of the economy and the automotive industry, people have begun to pursue better and better driving experience and higher driving safety. The head-up display in the automotive field is divided into windshield type and integrated display type, which can display important driving information on the glass, and the driver can observe the driving information without lowering his head, which greatly reduces the driver's line of ...
