Definitions
- the invention relates to a vehicle pane for a head-up display, a method for its production and its use, and a head-up display with the vehicle pane and a vehicle equipped accordingly.
- Head-up displays are provided for displaying image information for a viewer or driver.
- a projector as an image generator, for example in the area of the dashboard or in the roof area, images are projected onto the windshield, reflected there and perceived by the driver as a virtual image behind the windshield.
- important information can be projected into the driver's field of vision, for example the current driving speed, navigation or warning information, which the driver can perceive without having to take his eyes off the road. Head-up displays can thus make a significant contribution to increasing traffic safety.
- Vehicle windshields usually consist of two panes of glass which are laminated to one another via at least one thermoplastic film.
- the head-up display described above has a problem that the projected 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 secondary image, which is usually of weaker intensity, which is caused by the reflection on the outside surface of the windshield (secondary reflection).
- This problem is commonly solved by arranging the reflective surfaces at a deliberately selected angle to one another, so that the main image and sub-image are superimposed, so that the sub-image is no longer distracting.
- head-up displays Another problem with head-up displays is the polarization of the light reflected from the laminated pane.
- s-polarized the proportion of light that is polarized perpendicularly to the plane of incidence
- the sunglasses must therefore be removed.
- the object of the present invention is to provide an improved head-up display with which these disadvantages can be avoided. It would be desirable to have a head-up display in which no unwanted secondary images occur and whose arrangement in the vehicle can be implemented relatively easily with good visibility and sufficient brightness and contrast of the displayed image information. In addition, the energy consumption should be relatively low and the HUD display should also be visible with sunglasses with polarized lenses. Furthermore, the head-up display should be easy and inexpensive to produce in the industrial series production of vehicles.
- a vehicle window is shown, which is used to separate a vehicle interior from the exterior of the vehicle.
- the vehicle pane includes at least one transparent pane.
- the vehicle window can have any be formed, in particular as thermally toughened single-pane safety glass or as a laminated pane.
- the vehicle window preferably serves as a vehicle windshield.
- the vehicle pane according to the invention in particular a vehicle windshield, is preferably designed as a composite pane and comprises a first pane with an outside and inside and a second pane with an inside and outside, which are firmly connected to one another by at least one thermoplastic intermediate layer (adhesive layer).
- the first pane can also be referred to as the outer pane, the second pane as the inner pane.
- the surfaces or sides of the two individual panes are usually referred to as side I, side II, side III and side IV from the outside to the inside.
- the vehicle pane according to the invention When installed in the vehicle, the vehicle pane according to the invention has an outside facing the external environment and an inside facing the vehicle interior.
- the outside of the first pane is the outside of the vehicle pane and the inside of the second pane is the inside of the vehicle pane.
- the vehicle pane according to the invention has at least one masking strip in an edge region which typically adjoins the edge of the pane.
- the at least one masking strip is a coating of one or more layers and is used to mask structures that are otherwise recognizable through the pane in the installed state.
- the masking strip is used to mask an adhesive bead for gluing the windshield into a vehicle body, i.e. it prevents the outward view of the adhesive bead, which is usually applied irregularly, so that the windshield creates a harmonious overall impression.
- the masking strip serves as UV protection for the adhesive material used. Continuous exposure to UV light damages the adhesive material and would loosen the connection between the pane and the vehicle body over time.
- the at least one masking strip comprises a colored, preferably black, colored material, which can preferably be burned into the pane.
- the at least one masking strip is preferably opaque in order to serve in particular as visual and UV protection, for example for a bead of adhesive.
- the masking strip can also be used, for example, to cover busbars and/or connection elements.
- transparent means that the total transmission of the vehicle pane corresponds to the legal provisions for windshields and preferably has a transmittance of more than 70% and in particular more than 75%, for example more than 95%, for visible light.
- "opaque” means a light transmission of less than 30%, in particular less than 25%, for example less than 5%, in particular 0%.
- the vehicle pane according to the invention also comprises at least one reflection layer (mirror layer) for reflecting light into the vehicle interior. It is essential here that the reflection layer is arranged in the region of the masking strip, on the vehicle interior side of the masking strip. In view of the inside of the vehicle window, the reflection layer is therefore in front of the masking strip.
- a reflection layer for reflecting light into the vehicle interior.
- the expression "in the region of the masking strip” means that the reflective layer is arranged in a vertical view through the vehicle window or in an orthogonal projection through the window in a covering or overlapping relationship with the masking strip.
- the reflection layer and the at least one masking strip can be arranged on different sides of the vehicle window or on the same side of the vehicle window.
- the reflective layer has no portion which is not overlapped with the masking stripe, i.e. the reflective layer is formed only where it is in front of the masking stripe as viewed from the inside of the vehicle glass.
- the expression "reflection of light into the vehicle interior” refers to the condition of the vehicle window installed in the vehicle. The reflected light leaves the vehicle window on the inside.
- the at least one reflection layer is assigned an image display device arranged in the interior of the vehicle.
- the image display device includes an image display whose image impinges on the reflective layer and is reflected by the reflective layer into the vehicle interior.
- the image display device can also be referred to as a display and can be in the form of a TFT display, LED display, OLED display, EL display, pLED display or the like.
- the reflective layer is suitably formed to reflect light of the image display device.
- the reflection layer is a coating of the pane that reflects the incident light and preferably comprises or consists of at least one elemental metal and/or at least one metal oxide.
- the metal is preferably selected from the group consisting of aluminum, tin, titanium, copper, chromium, cobalt, iron, manganese, zirconium, cerium, yttrium, silver, gold, platinum and palladium, or mixtures thereof.
- a paste is applied to the pane, for example by a vapor deposition method such as a CVD method, an atmospheric pressure plasma coating method, spraying (spray coating), or by a sol/gel method and, if necessary a subsequent baking or tempering.
- the paste is preferably applied to the pane in a printing process, in particular by means of screen printing, pad printing or offset printing.
- the applied paste is then burnt in, i.e. compacted by heat treatment.
- the applied paste is advantageously dried at a temperature of 50.degree. C. to 180.degree. C. and calcined at a temperature of 200.degree. C. to 1000.degree. C., in particular from 400.degree. C. to 700.degree.
- the paste comprises a printable metal solution, with at least one metal being predominantly bound as a complex.
- the paste can further comprise a solvent, preferably selected from alcohols, glycols, polypropylene glycols and derivatives thereof, and/or a thickening agent, preferably a cellulose derivative or polyacrylic acid.
- Such pastes for producing reflection layers are commercially available, for example from Ferro GmbH.
- such coatings are known from the patent literature, see for example WO 2005/063645.
- the reflective layer consists of at least one metal oxide, optionally at least one solvent and/or at least one thickener, and unavoidable impurities whose proportion in the reflective layer is less than 5% by weight, preferably less than 1% by weight.
- the content of metal oxide in the reflection layer is preferably at least 70%, preferably at least 80%, in particular at least 90%.
- the properties of the reflected light can be improved by the reflection layer compared to a mere reflection of the light on the pane.
- the reflection layer has a total reflectivity of light ( ⁇ ) in the visible wavelength range, measured at an angle of incidence of 65° to the normal, of greater than 15%, preferably greater than or equal to 25%.
- the light here preferably includes s-polarized and p-polarized light in the visible wavelength range.
- the proportion of reflected light is therefore comparatively high, with the reflectivity of light (RL) being approximately 25%, for example.
- the reflection layer has a reflectivity of p-polarized light (R P .L) in the visible wavelength range, measured at an angle of incidence of 65° to the normal, of greater than 5%, preferably greater than 15%.
- the visible wavelength range in the context of the present invention is preferably 380 nm to 780 nm.
- the reflection values mentioned above apply particularly preferably to s- and p-polarized light or to p-polarized light in the wavelength range used by the light source.
- the present invention is based on the finding that a reflective layer covering the at least one, typically opaque, masking strip enables a good image display with high contrast to the masking strip, so that it appears bright and is therefore also excellently recognizable. This advantageously enables a reduction in the performance of the image display device and thus reduced energy consumption. This is a great advantage of the invention.
- the head-up display according to the invention can be implemented cost-effectively and in a technically simple manner, with in particular only a relatively small area of the vehicle window having to be equipped with the reflection layer.
- the at least one masking strip is preferably applied to the at least one pane using a printing process, in particular a screen printing process.
- the ink will be on the Printed disc and then dried or baked at up to 700 °C, for example.
- the ink is preferably permanently lightfast, solvent and abrasion resistant.

- the at least one masking strip can be applied to each side of the pane.
- this is preferably applied to the inside (side II) of the first pane or to the inside (side III) of the second pane, where it is protected from external influences. It is particularly preferably applied to the inside (side II) of the first pane.
- the reflective layer is attached to the outside (side IV) of the second pane, which enables particularly simple manufacture.
- the proportion of reflected light is particularly high in this arrangement.
- disturbing secondary images can be avoided.
- the reflective layer is generally very stable to weathering, the reflective layer can be covered by a cover layer, in particular a polymer layer or a glass layer, in order to protect it from external influences.
- the glass layer can be attached to the laminated pane in particular by means of a thermoplastic intermediate layer.
- the reflection layer is on the inside (side III) attached to the second pane, which has the advantage that the reflective layer is protected from external influences.
- the reflection layer is applied to the inside (side II) of the first pane on or above the (opaque) masking layer.
- the proportion of the reflected light with p-polarization is particularly high in this arrangement, which has the advantage that the HUD display is also clearly visible with sunglasses with polarized glasses.
- One or more further layers can be arranged between the masking layer and the reflection layer.
- the reflection layer can be applied directly to the masking layer.
- the vehicle window in addition to the (opaque) masking strip on the inside (side II) of the first window, there is at least one further masking strip on the inside (III) of the second window and/or on the outside (IV) arranged on the second disc.
- the further masking strip is used to improve adhesion of the panes and is preferably mixed with ceramic particles that give the masking strip a rough and adhesive surface, which on page IV, for example, supports the gluing of the vehicle pane into the vehicle body. On side III, this supports the laminating of the two individual panes of the compound pane.
- the masking strip arranged on side II is preferably also mixed with ceramic particles.
- a further masking strip applied to the outside of the second pane (side IV) can also be provided for aesthetic reasons, for example in order to conceal the edge of the reflection layer or to design the edge of the transition to the transparent area.
- the masking strip is preferably provided with a broadening, i.e. has a greater width (dimension perpendicular to the extension) than in other sections. In this way, the masking stripe can be suitably adapted to the dimensions of the reflection layer.
- the at least one pane preferably contains or consists of glass, particularly preferably flat glass, float glass, quartz glass, borosilicate glass, soda-lime glass, alumino-silicate glass, or clear plastics, preferably rigid clear plastics, in particular polyethylene, polypropylene len, polycarbonate, polymethyl methacrylate, polystyrene, polyamide, polyester, polyvinyl chloride and/or mixtures thereof.

- Other plasticizers are preferably aliphatic diesters of triethylene or tetraethylene glycol. Particular preference is given to using 3G7, 3G8 or 4G7 as the plasticizer, the first digit denoting the number of ethylene glycol units and the last digit denoting the number of carbon atoms in the carboxylic acid part of the compound.

- the reflective layer 9 is arranged in a vertical view through the vehicle window 1 in overlap with the first masking strip 5, the first masking strip 5 covering the reflective layer 9 completely, ie the reflective layer 9 has no section that does not overlap with the first masking strip 5.
- the reflection layer 9 is arranged here, for example, only in the lower (engine-side) section 1 T of the edge area 11 of the vehicle window 1 .
- several reflective layers 9 could be provided, for example in the lower (engine-side) section 1T and in the upper (roof-side ) Section 11" of the margin empire 11 are arranged.
- the reflection layers 9 could be arranged in such a way that a (partially) circulating image is generated.
- the first masking strip 5 is widened in the lower (engine-side) section 1 T of the edge area 11, i.e. the first masking strip 5 has a greater width in the lower (engine-side) section 1 T of the edge area 11 than in the upper (roof-side) section 11" of the edge area 11 (as well as in the lateral sections of the edge region 11 that cannot be seen in Figure 1) of the vehicle window 1.
- “Width” is understood to mean the dimension of the first masking strip 5 perpendicular to its extension.
- the reflection layer 9 is arranged here, for example, above the second masking strip 6 (i.e. not in overlap), although it would be equally possible for there to be an overlap for aesthetic reasons.
- the head-up display 100 also has an image display device 8 arranged in the dashboard 7 as an image generator.
- the image display device 8 serves to generate light 10 (image information), which is directed onto the reflective layer 9 and is reflected by the reflective layer 9 as reflected light 10' into the vehicle interior 12, where it can be seen by an observer, e.g. driver.
- the reflection layer 9 is formed to reflect the light of the image display device, i.e. an image of the image display. It would also be possible, for example, to arrange the image display device 8 in the A-pillar of a motor vehicle or on the roof (in each case on the vehicle interior side), if the reflection layer 9 is positioned in a suitable manner for this purpose.
- a separate image display device 8 can be assigned to each reflection layer 9, i.e. several image display devices 8 can be arranged. It would also be possible, for example, for the vehicle window 1 to be a roof window, side window or rear window.
- the reflection layer 9 is shown extending along the lower section 1T of the edge area 11.
- FIGS. 3 to 4 correspond to the section line AA in the lower section 1T of the edge region 11 of the vehicle window 1, as indicated in FIG.
- the first (opaque) masking strip 5 is on the inside (side II) of the first pane 2.
- the reflection layer 9 is applied to the outside (side IV) of the second pane 3.
- Light 10 from the image display device 8 is reflected by the reflection layer 9 into the vehicle interior 12 as reflected light 10'.
- the polarizations of the light 10, 10' (s-polarization, p-polarization) are illustrated schematically.
- This variant has the advantage that a relatively large proportion of the incident light 10 is reflected.
- the image is easily recognizable against the background of the opaque (first) masking layer 5 with high contrast.
- the variant of the vehicle window 1 shown in FIG. 4 differs from the variant in FIG. 3 only in that the reflection layer 9 is applied to the (first) masking layer 5 .
- This variant has the particular advantage that a relatively large proportion of the incident light 10 is reflected with p-polarization.
- the image is easily recognizable against the background of the opaque (first) masking layer 5 with high contrast.
- the reflection layer 9 is well protected from external influences on the inside of the laminated pane.
- the reflective layer 9 is arranged on the vehicle interior side of the first masking strip 5, i.e. when looking at the inside of the vehicle window 1, the reflective layer 9 is located in front of the first masking strip 5.
- the measured total reflectivity R (in % of the incident light) as a function of the wavelength (nm) for various vehicle windows (composite windows) is shown in a diagram.
- the measurements were made at an angle of incidence of 65° to the normal.
- the curves F3B, F3C and F3D relate in this order to a vehicle window 1 with a reflection layer 9 on side IV and without masking layer 5 (F3B), a vehicle window 1 with a reflection layer 9 on side IV and with masking layer 5 (F3C), and a vehicle pane 1 with a reflective layer 9 on side II and with a masking layer 5, the reflective layer being arranged on the masking layer 5 (F3D).
- the total reflectivity is highest in the arrangement F3B, the total reflectivity in the arrangement F3C being lower but still comparatively good. In the case of the F3D arrangement, the total reflectivity is lower.
- the measured total reflectivity R (in % of the incident light) as a function of the wavelength (nm) is shown in a diagram for different vehicle windows according to Arrangements F3B, F3C and F3D are shown, with the total reflectivity R also being shown as a function of the s-polarization (s-pol) and p-polarization (p-pol) of the reflected light. These measurements were also made at an angle of incidence of 65° to the normal.
- the proportion of the s-polarized reflected light is particularly high in the arrangement F3B.
- the assemblies F3B, F3C and F3d have a higher total reflectivity in the p-polarization than the combination reflective foil.
- the proportion of the p-polarized reflected light is particularly high in the arrangement F3D and in particular higher than in the arrangements F3B and F3C.
- FIG. 7 uses a flowchart to illustrate the method according to the invention.
- a first step I at least one masking strip 5 is applied in the edge region 11 of the at least one pane 2, 3.
- at least one reflection layer 9 for reflecting light into the vehicle interior for displaying image information is arranged in the region of the masking strip 5, on the vehicle interior side of the masking strip 5.
- the invention provides an improved vehicle window or a head-up display equipped with it, which enables a good image display with high contrast to the masking strip. Unwanted secondary images can be avoided.
- the head-up display according to the invention can be produced simply and inexpensively using known production methods.
