Definitions

  • the invention relates to a composite pane and a projection arrangement for a head-up display.
  • Suitable coatings include conductive, metallic layers based on silver. Since these layers are susceptible to corrosion, it is common to apply them to the intermediate layer facing surface of the outer pane or the inner pane, so that they have no contact with the atmosphere.
  • Silver-containing transparent coatings are known, for example, from WO 03/024155, US 2007/0082219 A1, US 2007/0020465 A1, WO2013 / 104438 or WO2013 / 104439.
  • WO02007015861A2 and WO2013104439A1 disclose further composite panes with a heatable coating comprising three electrically conductive layers.
  • the electrically conductive coating should have the lowest possible sheet resistance.
  • the lowering of the sheet resistance is possible in particular by an increase in the amount of conductive material, that is, by a thicker configuration of the electrically conductive layers or a higher number of electrically conductive layers.
  • HUDs head-up displays
  • the driver not only perceives the desired main image caused by the reflection on the inside surface of the windshield (primary reflection).
  • the driver also perceives a slightly offset, generally low-intensity sub-picture, which is caused by the reflection on the outside surface of the windshield (secondary reflection).
  • the latter is commonly referred to as a ghost ("ghost").
  • This problem is commonly solved by arranging the reflective surfaces at a deliberately chosen angle to each other so that the main image and the ghost image are superimposed, whereby the ghost image is no longer distracting.
  • Windshields consist of two glass panes, which are laminated together via a thermoplastic film. If the surfaces of the glass sheets are to be arranged at an angle as described, it is customary to use a thermoplastic film of non-constant thickness.
  • a thermoplastic film of non-constant thickness One speaks of a wedge-shaped foil or wedge foil. The angle between the two surfaces of the film is called the wedge angle.
  • the wedge angle can be constant over the entire film (linear change in thickness) or change in a position-dependent manner (nonlinear change in thickness).
  • Laminated glasses with wedge foils are known, for example, from W02009 / 071135A1, EP1800855B1 or EP1880243A2.
  • WO2017157660A1 discloses a composite pane with an electrically conductive coating as a projection surface for a HUD. The layer ghosting is reduced by the use of a very thin inner pane. Requirements for the coating are not disclosed.
  • WO2017198363A1 also discloses a composite pane having an electrically conductive coating as a projection surface for a HUD.
  • the coating has four electrically conductive layers, with a total thickness of 57 nm.
  • US6068914A discloses a composite disk with an antireflection coating.
  • the invention has for its object to provide an improved composite disc with electrically conductive coating.
  • the composite disk should have a low sheet resistance despite a high transmission and be particularly suitable for a head-up display (HUD).
  • HUD head-up display
  • the advantages of the composite pane according to the invention are based on the combination of an electrically conductive coating with an antireflection coating.
  • the antireflection coating reduces the reflection of the composite disc, which increases its transmission in the visible spectral range.
  • the amount of the conductive material of the electrically conductive coating can be increased, in particular the layer thickness of the conductive layers contained, without the transparency being reduced to such an extent that the composite pane would no longer be suitable as a vehicle windshield.
  • increasing the amount of conductive material lowers the sheet resistance of the coating, thereby increasing its heating power at a given supply voltage.
  • the invention therefore enables the production of heated windshield with increased heating power.
  • the composite pane according to the invention comprises an outer pane and an inner pane, which are connected to one another via a thermoplastic intermediate layer.
  • the composite pane is intended, in a window opening, in particular the window opening of a vehicle, the interior space with respect to the external environment separate.
  • inner pane in the sense of the invention, the interior of the interior (in particular vehicle interior) facing disc of the composite pane is called.
  • outer pane the outer environment facing disc is called.
  • the composite pane is preferably a vehicle windshield (in particular the windshield of a motor vehicle, for example a passenger or heavy goods vehicle).
  • the composite disc has an upper edge and a lower edge and two side edges extending therebetween. With the upper edge that edge is referred to, which is intended to point in the installed position upwards.
  • the lower edge is the edge which is intended to point downwards in the installed position.
  • the upper edge is often referred to as the roof edge and the lower edge as the engine edge.
  • the outer pane and the inner pane each have an outer side and an inner side surface and an intervening, circumferential side edge.
  • the outside surface is that main surface which is intended to face the outside environment in the installed position.
  • interior side surface is referred to in the sense of the invention, that main surface, which is intended to be facing the interior in the installed position.
  • the inner side surface of the outer disk and the outer side surface of the inner disk face each other and connected to each other through the thermoplastic intermediate layer.
  • the composite pane is provided in a preferred embodiment for a head-up display and has a so-called HUD area.
  • the HUD area is the area that can be irradiated by a HUD projector.
  • the HUD area is intended to be irradiated by a projector for generating the HUD image. There, the radiation is reflected in the direction of the viewer (driver), whereby a virtual image is generated, which the viewer perceives seen from behind the windshield.
  • the composite pane also has a transparent, electrically conductive coating.
  • the electrically conductive coating is preferably applied to the outer surface of the inner pane facing towards the intermediate layer or on the inner side surface of the outer pane facing the intermediate layer.
  • the coating may alternatively be disposed within the intermediate layer.
  • This is the Coating typically applied to a carrier foil, for example of polyethylene terephthalate (PET) with a thickness of about 50 pm, which is arranged between two layers of thermoplastic material, for example between two polymer films.
  • PET polyethylene terephthalate
  • a transparent coating is understood as meaning a coating which has an average transmission in the visible spectral range of at least 70%, preferably at least 75%, which therefore does not significantly limit the viewing through the pane.
  • the composite pane also has an antireflection coating, which is applied on the interior side surface of the inner pane facing away from the intermediate layer.
  • the invention provides a composite disk with a high transmission in the visible spectral range and with a low sheet resistance of the conductive coating, which allows a high heating power.
  • composite disks with a transmission in the visible spectral range of at least 70% can be realized and with a sheet resistance of the electrically conductive coating of at most 0.65 W / p, preferably at most 0.60 W / p.
  • the transmission in the visible spectral range is determined according to the procedure defined by ECE-R 43, Annex 3, ⁇ 9.1 for testing the light transmission of vehicle windows.
  • the transmission in the visible spectral range is preferably at least 70.5%, more preferably at least 71%.
  • the electrically conductive coating can be provided, for example, as an IR-reflecting sunscreen coating or as a heatable coating, which is electrically contacted and heated when the current flows through.
  • at least 80% of the disk surface is provided with the coating according to the invention.
  • the composite disk is provided with the coating over its entire area, with the exception of a peripheral edge region and optionally local area, which are intended as communications, sensor or camera windows to ensure the transmission of electromagnetic radiation through the composite disk and are therefore not provided with the coating.
  • the circumferential uncoated edge region has, for example, a width of up to 20 cm. It prevents direct contact of the coating with the surrounding atmosphere, so that the coating inside the composite pane is protected against corrosion and damage.
  • the electrically conductive coating When the electrically conductive coating is provided as a heatable coating, it is typically provided with busbars connected to connecting cables which extend beyond the side edge of the composite disk.
