Embodiment Construction

[0025] see figure 1 , a vehicle-mounted head-up projection display device, including a projection device 2 and a reflective screen 3 arranged in the cab, the projection device 2 is connected with the vehicle information system (omitted in the figure); the projection device 2 is arranged between the vehicle driver 1 and the front windshield between glass 4. The reflective screen 3 is made of other transparent materials such as glass, plexiglass or transparent film, which can transmit light and reflect light. The reflective screen is glass or plexiglass; Layer or multi-layer coating, or coating, or coating, or film; such as magnesium fluoride, aluminum oxide, zirconium oxide, titanium oxide, or cerium oxide coating with a thickness greater than 500 nm. The reflective screen 3 is arranged independently of the vehicle windshield 4 ; the projection device 2 projects an image onto the reflective screen 3 to be perceived by the driver 1 . And the focal length of the line of sight ...

Abstract

The invention provides vehicle-mounted head-up projection display equipment. The equipment comprises a projection device and a reflecting screen which are arranged in a driving cab, wherein the projection device is connected with a vehicle-mounted information system; information required by a driver is projected to the reflecting screen in an optical mode through an optical means by the projection device, so that the information is transferred to the driver or a passenger; the equipment is characterized in that: the reflecting screen is arranged independent of devices which are not arranged for the purpose of reflecting light and can transmit light, such as windshield, glass for vehicle window and the like of vehicles. The reflecting screen is glass or organic glass and is provided with one or more plating layers, plating films, coating layers or sticking films for enhancing visible light reflection. By using the equipment, the cost of the vehicle-mounted projection display equipment can be reduced, the driving safety can be improved, and the design flexibility of the vehicle-mounted projection display equipment can be improved.

Description

technical field [0001] The invention relates to a vehicle-mounted man-machine interaction interface technology, in particular to a vehicle-mounted head-up projection display device. [0002] Background technique [0003] Head Up Display (Head Up Display), hereinafter referred to as HUD, is a flight aid commonly used in aircraft. Head-up means that the pilot can see the important information he needs without looking down. The head-up display first appeared on military aircraft, reducing the frequency of pilots needing to look down at the instruments, avoiding interruption of attention and loss of control over situation awareness (Situation Awareness). Because of the convenience of the HUD and the ability to improve safety. With the development of science and technology, vehicle head-up display (HUD) emerges as the times require. [0004] Vehicle-mounted head-up display (HUD) currently uses the front windshield as a reflective screen. For example, due to the high requireme...
