Definitions

  • Glazing with an operating device and method for manufacturing the glazing
  • the invention relates to glazing with an operating device, in particular in motor vehicles, and to a method for producing the glazing.
  • roof glazing is used in vehicles in a section of the body.
  • This glazing can be designed as classic glazing or as non-transparent glazing.
  • non-transparent glazing for example, printed or coated panes are used, which have a metallic appearance, for example.
  • An interior lighting device for a motor vehicle is known from DE 20 2005 014 791 U1.
  • an OLED screen is designed as a light source in such a way that it radiates into the interior of the vehicle.
  • the OLED screen can be arranged in the headliner of a motor vehicle, e.g. in a roof module.
  • the roof module can be designed as a transparent or partially transparent roof module, with the OLED screen being transparent or partially transparent when switched off, so that a roof module can function as a transparent or partially transparent sunroof despite the provision of the OLED screen.
  • Known OLED screens have a limited service life when exposed to sunlight or large temperature fluctuations.
  • DE 19927683 C1 discloses a composite glass pane made of at least two glass panes and a transparent composite layer connecting them and with a sun protection layer that reflects rays outside the visible spectrum of solar radiation, in particular infrared rays.
  • the laminated glass pane is provided on its surface facing an interior space with a further, transparent coating (low-E coating) that is spatially separate from the sun protection layer and essentially reflects heat rays.
  • Windshields are also known in which a sun visor is integrated in the form of a functional element with electrically controllable optical properties, in particular with electrically controllable transmission or scattering behavior. This allows the driver to control the transmission behavior of the windshield himself with regard to solar radiation, making the conventional mechanical sun visor unnecessary. Electrically controllable sun visors are also used in glass roofs of motor vehicles. Particularly in the case of large-area panoramic glass panes, there is a need to variably control the transmission of the pane. Depending on the position of the sun, it is only necessary to shade off partial areas of the pane, or to switch the entire surface opaque as a privacy screen in the parked vehicle.
  • Such an electrically switchable functional element for realizing controllable sun visors is a so-called PDLC (polymer dispersed liquid crystal) functional element.
  • the active layer contains liquid crystals embedded in a polymer matrix. If no voltage is applied, the liquid crystals are aligned in a disorderly manner, which leads to strong scattering of the light passing through the active layer. If a voltage is applied to the surface electrodes, the liquid crystals align in a common direction and the transmission of light through the active layer is increased.
  • the PDLC functional element works less by reducing the overall transmission than by increasing the scatter in order to ensure anti-glare protection.
  • Windshields with electrically controllable sun visors are known, for example, from DE 102013001334 A1, DE 102005049081 B3, DE 102005007427 A1 and DE 102007027296 A1.
  • DE 102010021563A1 describes a windshield with an electrically controllable sun visor that can be switched in some areas, with the darkening of the individual elements being controllable via a capacitive sensor arrangement in the edge area of the sun visor.
  • bus bars which are applied to the surface electrodes in the edge area of the functional element and contact them in an electrically conductive manner.
  • an external voltage source for example via flat conductors attached to the bus bars, a voltage is applied to the surface electrodes and the active layer of the functional element is switched.
  • US 8,519,362 B2 to Saint-Gobain describes a HUD system to be installed in a car. It is based on a laminated windshield where the HUD function comes from a layer of luminophore material.
  • US Pat. No. 7,230,767 B2 describes a display system in a car window pane, in which a light-emitting Material is used that projects the image to the driver. The image is a virtual image focused meters away from the driver's eyes and the windshield.
  • WO 2020/143996 A1 discloses a device and a method for displaying a digital image on a geometric and photometric non-trivial surface.
  • the document discloses projecting an image onto a windshield comprising laminated glazing with a switchable liquid crystal layer.
