Embodiment Construction

[0033] The present invention can be applied to segmenting multiple groups of images, and the following is an example of segmenting two images for illustration, but is not limited thereto; please refer to figure 1 and figure 2 . The present invention includes a display unit 10, which generates at least one image, which includes at least one external signal and at least one vehicle signal. The external signal is a signal related to vehicle safety such as lane lines, horizontal lines, obstacle outlines, and the distance between vehicles in front or the like. Image; vehicle signals include vehicle operating temperature, rotational speed, speed per hour, guidance information, tire pressure, shift reminder, steering, reverse reminder, obstacle warning, flight altitude, flight speed, heading, vertical speed change, vehicle Bank angle, wind direction information, signals of vehicle traveling or idling. The above image is refracted by a refraction element 12. The refraction element ...

Abstract

The invention discloses an image segmentation type virtual image display device comprising a display unit, a refraction element and a virtual image generation module; the refraction element is positioned between the display unit and the virtual image generation module. Firstly, the display unit generates at least one image, and the image is refracted by the refraction element and segmented into a plurality of sub-images. Finally, the light of the sub-images is reflected by the virtual image generation module so as to generate one large area virtual image or a plurality of amplified virtual images. The image segmentation technical method can be employed to reduce the element size of the virtual image generation module, and different display information is provided.

Description

technical field [0001] The present invention relates to a display device, in particular to an image split virtual image display device. Background technique [0002] Head Up Display (HUD) is the earliest flight aid instrument implemented on aircraft, which allows the driver to see the information on the instrument without looking down, so as to avoid interruption of attention and loss of state awareness ( Situation Awareness), because the use of the head-up display device is not only convenient but also can improve flight safety, and can be used on any kind of mobile vehicle, not only civil aircraft, but also cars and ships. [0003] Most of the prior art or existing products belong to a single optical path system, which can only display information within a fixed range. The screen is small and can only provide simple speed information, small arrow guidance system or vehicle information. In addition, in 2012, Audi announced the concept prototype of a head-up display system ...
