DISPLAY DEVICE
The invention relates to a display device for emission parameters of an internal combustion engine with a linear representation of a value range, wherein a first and a second part region are provided for the display of difference values with differing sign relative to a given set value.
1 . A display device for emission parameters of an internal combustion engine, comprising:
a line providing a linearly displayed value range;
a marker that is movable along the line; and
a marker that is fixed along the line,
wherein the value range comprises a first subrange for displaying positive values and a second subrange for displaying negative values.
2 . The display device as claimed in claim 1 , characterized in that the movable marker is formed by the tip of a pointer that is physically present or embodied as a graphic symbol.
3 . The display device as claimed in claim 1 , wherein the movable marker is embodied by influencing an optical property of one or more neighboring elements that are provided in a fashion fixed along the value range line.
4 . The display device as claimed in claim 1 , wherein the fixed marker is arranged at the division point between the subranges of the value range.
5 . The display device as claimed in claim 1 , wherein the value range has scaling.
6 . The display device as claimed in claim 5 , the scaling is implemented either proportionally or non-proportionally or as a mixed form composed of these two possibilities.
7 . The display device as claimed in claim 5 , wherein the scaling is designed in a way that can be altered.
8 . The display device as claimed in claim 6 , wherein the scaling is designed in a way that can be altered.
