【0039】 好適には、制御装置は、助手席が空いている場合には、その助手席に割当てられている表示領域の輝度を自動的に低減させるか、又はこの表示領域における照明を完全にデアクティブ状態にするように構成されている。これによって、車両運転手には無関係の表示領域の輝度が自動的に低減される。つまり、車両運転手は同乗者に割当てられている表示領域によって気を逸らされることは少なくなり、更には、この表示領域の輝度の手動の調整に意識を集中する必要はない。これによって、車両運転手は運転プロセスに認知的に意識を集中させることができるので、道路交通における安全性が更に改善される。

Abstract
Claims
1. A display device (1) includes a display surface (2), a plurality of pixel elements arranged within the display surface (2), a plurality of light-emitting elements arranged within the display surface (2), and a control unit (3) for controlling the pixel elements and the light-emitting elements, The light-emitting element is positioned behind the pixel element when viewed from the line of sight to the display surface (2) in order to illuminate the pixel element from behind, or the light-emitting element is formed by the pixel element itself, and the display surface (2) is divisible into at least two separate display areas (2.1, 2.2). The display device (1) is characterized in that the control unit (3) is configured to individually change the brightness of the display areas (2.1, 2.2, 2.3, 2.4) by individually controlling each light-emitting element.
2. The display device (1) according to claim 1, characterized in that the control unit (3) is configured to distribute the display areas (2.1, 2.2, 2.3, 2.4) having different brightness levels to the display surface (2) independently of the image content reproduced on the display surface (2).
3. The display device (1) according to claim 1 or 2, characterized in that the control unit (3) is configured to change the number and / or distribution of the display areas (2.1, 2.2, 2.3, 2.4) having different brightness levels.
4. The display device (1) according to any one of claims 1 to 3, characterized in that the control unit (3) is configured to receive commands from an external content source (4) for controlling the pixel elements and / or the light-emitting elements, the commands include the image content to be reproduced and define the division of the display surface (2) into the display areas (2.1, 2.2, 2.3, 2.4).
5. The display device (1) according to claim 4, characterized in that the control unit (3) is configured to receive the image content to be reproduced and the definition of the division of the display surface (2) via the same data line (5).
6. The control unit (3) is configured to provide at least one transition region (6) between two adjacent display regions (2.1, 2.2), wherein the brightness in the transition region (6) gradually increases, and the start value and end value correspond to the brightness of the adjacent display regions (2.1, 2.2), characterized in that the display device (1) is as described in any one of claims 1 to 5.
7. The display device (1) according to any one of claims 1 to 6, characterized in that the control unit (3) is configured to set the brightness of all display areas (2.1, 2.2, 2.3, 2.4) to a common reference value in response to an error.
8. The display device (1) according to claim 7, characterized in that the common reference value corresponds to the brightness of the reference display area.
9. The display device (1) according to any one of claims 1 to 8, characterized in that, when the display surface (2) is divided into two or more display areas (2.1, 2.2, 2.3, 2.4), the control unit (3) receives a command to set the brightness of all display areas (2.1, 2.2, 2.3, 2.4) to a uniform target value (7), and then sets the brightness of the display areas (2.1, 2.2, 2.3, 2.4) in order to gradually adjust to the target value (7) according to the difference from the target value (7).
10. The control unit (3) is configured to first change the brightness (H3) of the display area (2.3) with the largest difference (Δ3) from the target value (7), and when it reaches the brightness difference (Δ1) of the display area (2.1) with the next largest difference, it changes the brightness (H1, H3) of all display areas (2.1, 2.2, 2.3) together until all of them reach the target value (7), and the control unit (3) is configured to only start changing the brightness (H1) of the display area (2.1) with a relatively small difference (Δ1) from the target value (7) when the brightness (H3) change of the display area (2.3) has already started to reach the brightness (H1) of the display area (2.1) with a relatively small difference (Δ1), the display device (1) according to claim 9.
11. A vehicle characterized by being provided with a display device (1) according to any one of claims 1 to 10.
12. The vehicle according to claim 11, characterized in that the display device (1) is integrated into the dashboard (9), extends continuously across the dashboard (9) in the direction of the vehicle's transverse axis from the driver's side to the passenger's side, the display surface (2) is divided into at least three display areas (2.1, 2.2, 2.3), the first display area (2.1) is provided in front of the driver's seat in the direction of the vehicle's longitudinal axis, the second display area (2.2) is provided in front of the passenger seat, and the third display area (2.3) is provided between the first display area (2.1) and the second display area (2.2) in the direction of the vehicle's transverse axis.
13. A vehicle according to claim 11 or 12, characterized in that a presence determination means and a control device are provided, the control device is configured to read sensor data from the presence determination means to identify whether or not a vehicle occupant is present on a vehicle seat and on which vehicle seat, and to change the display of an adjustment means for adjusting the brightness of the display areas (2.1, 2.2, 2.3) in the display surface (2) and / or to automatically change the brightness of at least one display area (2.1, 2.2, 2.3).
14. The vehicle according to claim 13, characterized in that the control device is configured to automatically reduce the brightness of the display area (2.2) assigned to the passenger seat when the passenger seat is empty, or to completely deactivate the lighting in the display area (2.2).
