Definitions

  • the invention relates to a composite pane, in particular for a projection arrangement, its use in a vehicle, and a method for its production.
  • HMIs Human Machine Interfaces
  • human-machine interfaces and displays are essential and important topics and functionalities in the automotive sector.
  • the size and number of displays and display systems, especially in the cockpit of motor vehicles, is increasing more and more.
  • the display and playback of navigation, security and telecommunications information, as well as additional infotainment, is now an almost essential standard.
  • HUD head-up displays
  • imaging unit which uses an optical module and a projection surface to project an image that is perceived by the driver as a virtual image. For example, if this image is reflected on the vehicle windshield as a projection surface, important information can be displayed for the user, which significantly improves traffic safety.
  • the problem with the head-up displays described above is that the projector image is reflected on both surfaces of the windshield.
  • the driver not only perceives the desired main image, which is caused by the reflection on the interior surface of the windshield (primary reflection).
  • the driver also perceives a slightly offset, usually less intense secondary image, which is caused by the reflection on the outside surface of the windshield (secondary reflection).
  • the latter is also commonly referred to as ghosting or “ghost image”.
  • This problem is commonly solved by arranging the reflective surfaces at a deliberately chosen angle to one another so that the main image and ghost image are superimposed, whereby the ghost image is no longer disturbing.
  • the radiation from the head-up display projector is typically essentially s-polarized due to the better reflection characteristics of the windshield compared to p-polarization.
  • the driver wears polarization-selective sunglasses, which only or essentially p-polarized light is transmitted, he can hardly or not at all perceive the HUD image.
  • polarization-selective sunglasses which only or essentially p-polarized light is transmitted, he can hardly or not at all perceive the HUD image.
  • a solution to the problem in this context is therefore the use of projection arrangements that use p-polarized light.
  • DE102014220189A1 discloses a head-up display projection arrangement which is operated with p-polarized radiation to generate a head-up display image. Since the angle of incidence is typically close to the Brewster angle and p-polarized radiation is therefore only reflected to a small extent by the glass surfaces, the windshield has a reflective structure that can reflect p-polarized radiation in the direction of the driver.
  • the proposed reflective structure is a single metallic layer with a thickness of 5 nm to 9 nm, for example made of silver or aluminum, which is applied to the outside of the inner pane facing away from the interior of the car.
  • EP20200006.3 and EP20200009.7 show the use of a masking strip in the edge area of the windshield with a transparent element arranged in front of the masking strip, which reflects the image projected onto the element into the vehicle interior. Due to the opaque background, the image can be perceived with a higher contrast.

Alternatively, only the areas that are intended to conceal the outcoupling device can be formed as a semi-mirror layer.

One way to achieve this is to partially mask the pane during the coating step or alternatively to apply a carrier film used for the reflective layer to the pane.
