Head-up display device

Abstract

The invention provides a head-up display device at least comprising an image display unit capable of generating one or more input images and a rotary mechanism, wherein at least one virtual image generating element is used for receiving the input images and generating at least one virtual image, and the rotary mechanism enables the virtual image generating element to change the projection angle of the virtual image so that the virtual image is projected to a plurality of perspective plane mirrors and correspondingly received and the virtual image of a large area is formed through reflection. The head-up display device can directly reduce the size of a lens or an optical element of a mirror, is miniaturized but has a large image display range. A required carrier information image is totally overlapped with an external image, and the problems that a single-light-path image display device is used in the past, images can only be displayed in a small area, and the images can not be displayed in a large area are solved.

Description

technical field [0001] The invention relates to an optical system architecture, in particular to a head-up display device suitable for a mobile vehicle. Background technique [0002] As we all know, the Head Up Display (HUD) in the past is a flight aid instrument used on aircraft, which allows the driver to see the information on the instrument without looking down, so as to avoid interruption and loss of attention The mastery of situation awareness (Situation Awareness), because the use of the head-up imaging device is very convenient and can improve flight safety, it can also be used on other types of mobile vehicles, not only civil aircraft, but even cars and Ships are also available. [0003] In the past, the head-up display function in the prior art only provides some simple instrument data information with a very small display range area within the driver's line of sight, so as to display any relevant information about the mobile vehicle. Key information, and most of...

Problems solved by technology

[0005] The main purpose of the present invention is to provide a head-up display device, which utilizes the rotating mechanism to divide the image signal into parts for individual projection, and then supplements the technical means of re-gathering and displaying the image. The present invention can use the same lens or mirror The size of the optical components can be used to produce a larger imaging area, or the size of the optical components of the lens or mirror can be reduced, thereby reducing the volume of the head-up display device, and a large-area imaging effect can be achieved in the limited installation space in the car , the information screen provided by the head-up display device can be completely superimposed with the external scene or the information screen can be displayed in conjunction with the corresponding scene, which can help the driver pay attention to the key information of the mobile vehicle, and effectively solve the problem of single optical path imaging in the past The problem that the device can only display in a small area
