Embodiment Construction

[0016] refer to figure 2 , image 3 and Figure 4 , which are respectively a schematic diagram of an optical path, a schematic diagram of a grating structure deflecting an optical image, and a first schematic diagram of a refracting surface refracting an optical image according to an embodiment of the head-up display device of the present invention. In the figure, the head-up display device includes a display module 21 , a polarizing component 22 and a reflective module 24 .

[0017] The display module 21 generates an optical image 211 , and the optical image 211 is projected from above the display module 21 . A power connection line (not shown) is electrically connected to the display module 21 to provide power required by the display module 21 . The polarizing component 22 is disposed above the display module 21 , the polarizing component 22 is an angle filter film and has a plurality of grating structures 221 .

[0018] When the optical image 211 is projected through t...

Abstract

The invention relates to a head-up display device, which comprises a display module, a light polarizing assembly and a reflection module. The display module generates an optical image; the light polarizing assembly is arranged on one side of the display module and limits the optical image to be projected through a preset route; and the reflection module reflects the optical image projected by the light polarizing assembly, wherein the light polarizing assembly is a grating film which enables the optical image to be projected only along the preset route so that a ghost image effect generated by the secondary reflection of the optical image due to a windscreen is avoided.

Description

technical field [0001] The invention relates to a head-up display device, in particular to a head-up display device capable of avoiding ghost images generated by the head-up display device and enabling drivers to see clear optical images. Background technique [0002] At present, the image display method of the Head Up Display (HUD) is to paste a reflective film on the windshield of the vehicle, so that the optical image projected by the head-up display is reflected by the optical reflective film such as thermal insulation paper and then projected to the driver's eyes. In the eyes, to inform the driver of the current speed and other information. Due to the use of the head-up display to display information, the driver does not need to swing his head to watch the speedometer, thereby increasing driving safety. [0003] However, the European Window Films Association (EWFA) or the German ABG specification (ALLGEMEINE BAUMASCHINEN-GMBH, ABG) in order to avoid the visible light t...
