Claims

[1] Display arrangement for a vehicle, comprising a windshield (1) of the vehicle, a head-up display of the vehicle with a first display screen (3) of the head-up display arranged behind the windshield (1) with respect to an x-direction (4) of the vehicle and a second display screen of the head-up display arranged between the windshield (1) and the first display screen (3) with respect to the x-direction (4), and a defrosting system (2) of the vehicle assigned to the windshield (1) with an air nozzle (20) which is aligned with a reflection region (10) of an inner surface of the windshield (1) assigned to the first display screen (3) and the second display screen and is arranged next to the second display screen with respect to a y-direction (5) of the vehicle. [2] Display arrangement according to claim 1, wherein the air nozzle (20) is arranged in front of the first display screen (3) with respect to the x-direction (5). [3] Display arrangement according to claim 2, wherein the defrosting system (2) comprises a plurality of air nozzles (20) arranged side by side. [4] Display arrangement according to claim 3, wherein an orientation of the air nozzles (20) varies such that an angle of incidence formed with the inner surface of an air flow (6) blown out by the air nozzles (20) decreases gradually with an increasing distance from the reflection region (10). [5] Display arrangement according to one of claims 1 to 4, wherein the defrosting system (2) comprises at least two air nozzles (20) which are arranged on opposite sides of the reflection area (10) with respect to the y-direction (5). [6] Display arrangement according to claim 5, wherein the defrosting system (2) comprises an air duct (7) connecting the at least two air nozzles (20) and extending behind the first display screen (3) with respect to the x-direction (4). [7] Display arrangement according to one of claims 1 to 6, wherein the reflection area (10) comprises a black print area of the windshield (1) reflecting the second display screen. [8] Display arrangement according to one of claims 1 to 7, in which the defrosting system (2) comprises a window heater integrated at least in the reflection area (10). [9] A vehicle comprising a display arrangement according to any one of claims 1 to 8.
