Problems solved by technology

[0008] 1. In the above-mentioned prior patents, some of them use a single projection device to project vertical cutting images, but the disadvantage is that the projected standard distance images are too short, and the driver is prone to visual dizziness when watching, which affects to driving safety
[0009] 2. Although some prior patents can project standard-distance images and longer-distance images through two or more projection devi

Example

[0037] Such as figure 2 Shown is the first embodiment of the head-up display device for remote imaging provided by the present invention, including:

[0038] An image projection module 1 is arranged above the instrument panel A under the windshield W of a vehicle, and projects an image. The image projection module 1 is a digital light processing (Digital Light Processing, abbreviated as DLP). The projection device 1 uses a display technology used in projectors and rear projection televisions);

[0039] A reflective diffuser 2 is arranged at the junction of the ceiling C of the vehicle and the windshield W. The light path L of the output light source of the image projection module 1 is projected to the reflective diffuser 2, and is placed on the reflective diffuser 2. 2, the reflective diffuser 2 becomes a screen for displaying images. The reflective diffuser 2 also includes a rotating shaft 21. The position of the image projected under the windshield W can be adjusted by the rotat...

Abstract

The invention discloses a head-up display device for remote image displaying. The head-up display device comprises an image projection module, a reflective diffusion sheet and a concave mirror module.On the basis of cooperation of the reflective diffusion sheet and the concave mirror module, the reflection distance is increased to obtain a long optical path distance. A virtual image at a long projection distance can be obtained under the same concave mirror amplification factor, so that the visual dizzy feeling of the driver is reduced and the optimal visual effect is obtained and thus the driving safety is enhanced.

Description

technical field [0001] The invention relates to a head-up display device for long-distance imaging, especially a head-up display device that can reduce the driver's visual dizziness. It uses a reflective diffuser and a concave mirror module to increase the reflection distance to obtain a longer distance. With a long optical distance, a virtual image with a longer projection distance can be obtained under the same magnification of the concave mirror, so as to reduce the driver's visual dizziness and obtain the best visual effect, thereby improving driving safety. Background technique [0002] At present, the HUD technology used in automobiles is not as complicated as that used in aircraft; it is an optical system, generally composed of two main devices: a projector and an image mirror. The projector is composed of a signal light source, a The projection mirror is composed of other optical components. The signal light source of the projector is composed of an LCD liquid crysta...
