Vehicle pane for a head-up display
A vehicle pane for a head-up display having an outer face that faces external surroundings in the installed state and an inner face that faces a vehicle interior, includes at least one transparent pane; at least one masking strip in an edge region of the pane, and at least one reflection layer for reflecting light which is applied by printing, which is arranged in the region of the masking strip, on the vehicle-interior side of the masking strip.
1. A vehicle pane for a head-up display having an outer face that faces external surroundings in an installed state and an inner face that faces a vehicle interior, comprising:
at least one transparent pane,
at least one masking strip in an edge region of the pane,
at least one reflection layer for reflecting light, the at least one reflection layer being a coating covering a portion of a face of the vehicle pane and arranged in a region of the masking strip, on a vehicle-interior side of the masking strip so as to overlap the at least masking strip in said region.
2. The vehicle pane according to claim 1 , which is implemented in the form of a composite pane and comprises a first pane with an outer face facing the external surroundings in the installed state and an inner face and a second pane with an outer face that faces the vehicle interior in the installed state and an inner face, which first and second panes are fixedly joined to one another by at least one thermoplastic intermediate layer.
3. The vehicle pane according to claim 2 , wherein the at least one masking strip is applied to the inner face of the first pane.
4. The vehicle pane according to claim 3 , wherein the reflection layer is attached on the outer face of the second pane.
5. The vehicle pane according to claim 3 , wherein the reflection layer is attached on the inner face of the second pane.
6. The vehicle pane according to claim 3 , wherein the reflection layer is attached on the inner face of the first pane on the masking layer.
7. The vehicle pane according to claim 2 , wherein the at least one masking strip is arranged on the inner face of the first pane and at least one further masking strip is arranged on the inner face of the second pane and/or on the outer face of the second pane.
8. The vehicle pane according to claim 1 , wherein the at least one masking strip is formed circumferentially as a frame and has, in a section that overlaps the reflection layer, a greater width than in sections different therefrom.
9. The vehicle pane according to claim 1 , wherein the reflection layer contains at least one elemental metal or one metal oxide.
10. The vehicle pane according to claim 9 , wherein the metal is selected from the group consisting of aluminum, tin, titanium, copper, chromium, cobalt, iron, manganese, zirconium, cerium, yttrium, silver, gold, platinum, palladium, and mixtures thereof.
11. The vehicle pane according to claim 9 , wherein the reflection layer is produced by printing a paste containing an elemental metal or a metal oxide onto the pane and then baking the paste.
12. The vehicle pane according to claim 1 , wherein the reflection layer has reflectivity of p-polarized light in the visible wavelength range, measured at an angle of incidence of 65° relative to the normal, of greater than 5%.
13. The vehicle pane according to claim 12 , wherein the reflection layer has reflectivity of p-polarized light in the visible wavelength range, measured at an angle of incidence of 65° relative to the normal, of greater than 15%.
14. A head-up display, comprising:
a vehicle pane according to claim 1 ,
an image display device associated with the reflection layer and having an image display directed at the reflection layer, the image of which is reflected by the reflection layer into the vehicle interior.
15. A vehicle with a head-up display according to claim 14 .
16. A method for producing a vehicle pane according to claim 1 , comprising:
applying at least one masking strip in an edge region of the at least one pane,
arranging a reflection layer for reflecting light in the region of the masking strip, on the vehicle-interior side of the masking strip.
17. A method comprising providing a vehicle pane according to claim 1 in a vehicle for traffic on land, in the air, or on water.
18. The method according to claim 17 , wherein the vehicle pane is a vehicle windshield.
19. The vehicle pane according to claim 1 , wherein the at least one reflection layer for reflecting light is applied by printing.
20. The vehicle pane according to claim 1 , wherein the reflecting layer is adapted to reflect light of an image display device of the head-up display.
