Embodiment Construction

[0031] figure 1 A vehicle 1 is shown in which a projection display device 2 according to the invention is installed at the driver's seat. A control unit 5 generating image signals and an optical imaging unit 4 are installed in a dashboard 9 . The combination element 3 is placed directly in front of the windshield glass 6 from the driver's line of sight, wherein the installation method of the combination element is figure 1 not shown in . The upper edge of the composite element 3 is located below the driver's eye level, which can be seen from the line of sight 12 . In this case, the combination element 3 covers the visual field between the sight lines 10a and 10c in the vertical direction. Reflective surface 3 is reflective over its entire surface facing the driver. Thus, the image points of the display to be imaged can be seen through the viewing angle lying between rays 10 a and 10 c. The line 11 describes the beam path of such an image point by way of example.

Abstract

The present invention relates to a projection display device for vehicles, having a flat combined element, and capable of improving sensuality of information to be showed and visible circumference landscape behind the combined element. To this end, the combined element is provided with an area, by which an interferential contour or light reflection can be blocked.

Description

technical field [0001] The invention relates to a projection display device for a vehicle according to the preamble of claim 1 and a vehicle with a projection display device according to claim 14 and to a projection display device according to the preamble of claim 15 A method for operating a projection display device. Background technique [0002] Projection displays for vehicles, also known as head-up displays (head-up displays), display information by reflection on transparent surfaces, for example vehicle windows. Here, the displayed information is projected into the observer's eyes as a virtual image and can be perceived simultaneously with the surroundings visible behind the reflective surface. Combined projection display devices, so-called combined head-up displays, have their own transparent reflective surfaces. The projection display device is arranged in the vehicle interior as an additional device element, referred to below as a combination element, in the direc...
