Display device and control system for potentially dangerous technical systems

2:

• The display device according to claim 1, wherein the representation or information visualized cumulatively by the first and the at least one second display (21, 22) is formed by at least one symbol (27), which symbol (27) is provided for manual operation and/or monitoring of technical systems which can be controlled and influenced manually.

3:

• The display device according to claim 2, wherein the at least one symbol (27) is formed by a symbol for a machine operation, in particular according to standard EN 60204-1 or IEC 60417.

4:

• The display device according to claim 1, wherein the first display (21) and the at least one second display (22) are configured to generate, by subtractive or additive color mixing of a first color (33) as first display content (24) or for the first display content (24), and a second color (34) as second display content (26) or for the second display content (26), a mixed color (35) which can be perceived by a user as plausible or planned.

5:

• The display device according to claim 1, wherein the first display (21) and the at least one second display (22) are configured to display at least a portion of the representation or information to be visualized on the first display (21) and the at least one completing portion of the representation or information to be visualized on the at least one second display (22).

6:

• The display device according to claim 1, wherein a touch-sensitive, transparent or at least partially translucent input means (32) for the manual input of control or operating commands is arranged upstream of the at least one second display (22) in the normal direction to its second display surface (25).

7:

• The display device according to claim 1, wherein the at least one second display (22) is configured as an OLED display.

8:

• The display device according to claim 1, wherein the first display (21) is configured as an LCD display with backlighting.

9:

• The display device according to claim 1, wherein a common display control device (28) and/or a first and at least one second display control device (29, 30) is/are configured, which is/are configured to respectively proportionally display the color representations on the first and the at least one second display (21, 22) and/or to mutually supplement or complete the overall graphic representations to be displayed on the first and the at least one second display (21, 22).

11:

• A use of the display device (20) according to claim 1 as fail-safe display means in control systems (1) of potentially dangerous technical systems, such as industrial plants, machines or motor vehicles.

13:

• The method according to claim 12, wherein the information cumulatively visualized by the first display (21) and the at least one second display (22) is formed by at least one symbol (27), which symbol (27) is used for manual operation and/or monitoring of technical systems which can be manually controlled and influenced.

14:

• The method according to claim 12, wherein the first display (21) and the at least one second display (22) are used in such a way that a mixed color (35) is generated by subtractive or additive color mixing of a first color (33) as first display content (24) or for the first display content (24), and a second color (34) as second display content (26) or for the second display content (26), which mixed color can be perceived by a user as plausible or planned.

15:

• The method according to claim 12, wherein the first display (21) and the at least one second display (22) are used such that at least a portion of the information or representation to be visualized is displayed on the first display (21) and at least a completing portion of the information or representation to be visualized is displayed on the at least one second display (22).

16:

• The method according to claim 12, wherein a touch-sensitive, transparent or partially translucent input means (32) is arranged upstream of the at least one second display (22) in the direction normal to the second display surface (25), via which input means (32) control or operating commands desired by a user can be entered manually and are used for operating and/or monitoring potentially dangerous technical systems, such as industrial plants, machines or motor vehicles.
