Embodiment Construction

[0029] In the following, if not stated otherwise, the same reference symbols are used for identical and identically acting elements.

[0030] figure 1 A schematic side view of a display system with a display D1 that emits display light directly into the eyes of an observer 3 by means of a sub-beam L1 is shown. The observer, for example the driver of the vehicle, his co-driver or an occupant in the rear seat of the vehicle, is always referred to below with the reference number 3, wherein in figure 1 The observer 3 is represented by the observer's eyes in the subsequent figures. A display or display device D1 is provided on the instrument panel / dashboard 1 . Display D1 can generate beamlets L1 from the display film in such a way that display D1 is translucent and observer 3 is only slightly affected with regard to his field of view. The windshield 2 of the vehicle has no role in such a display system according to the prior art. In particular, translucent displays are complex...

Abstract

The invention relates to a vehicle display system for displaying a virtual image and a method for displaying a virtual image. The display system has a projection device, which is configured to emit display light in order to generate an image, and a reflecting device, which is configured for a first reflection of display light of the projection device arranged above the reflecting device by way of the reflecting device attached in or on an instrument panel of the vehicle. The display light of the projection device incident on the reflecting device is substantially retro-reflected. The display system further includes a windshield of the vehicle, which windshield is configured for a second reflection of at least part of the display light, which was reflected by the reflecting device, to the eyes of an observer in the vehicle in order to allow the observer to see, behind the windshield, the virtual image of the image generated by the projection device. The invention further relates to a method for displaying a virtual image in the vehicle.

Description

technical field [0001] The present disclosure relates to a vehicle display system for displaying virtual images. The present disclosure also relates to a method for displaying a virtual image for a vehicle. Background technique [0002] Based on the development activities for virtual display systems in vehicles, some problems are known to be solved. Displays within the vehicle are often used to present driving-related information, such as information on navigation, range of travel, speed, etc., but increasingly also information on entertainment (also known as Entertaining), such as videos, cover art, etc. information. The display system can be divided into direct display and so-called head-up display, direct display such as liquid crystal display (LC-Display, LC: Liquid Crystal, liquid crystal), organic light-emitting semiconductor display (OLED-Display, OLED: Light-emitting semiconductors); the head-up display (HUD-Display, HUD: Head-Up-Display, i.e. head-up display devi...
