Definitions
- the invention is based on a display device for a vehicle for displaying at least two display sizes assigned to one another with kilometers of scale segments.
- Display devices of the type mentioned here serve, for example, to regulate the driving speed of a motor vehicle.
- the programmable setting variable for the speed control referred to as the desired speed
- This setting speed is generally not displayed.
- the desired setting speed is shown by a separate display which is separate from the conventional speed display device.
- the display device according to the invention with the features mentioned in claim 1 has the advantage over the fact that the driver of the vehicle can easily detect two display sizes assigned to one another, here the current driving speed and the desired speed, so that driving safety is significantly increased.
- two separate lighting devices are provided, one of which is assigned to a plurality of scale segments of the display device and the other has individual lighting elements each belonging to a single scale segment.
- the display of the current speed can be displayed continuously, while the speed value which corresponds to the desired speed can be raised by the second lighting device.
- the scale segments, which represent the target speed can be clearly distinguished by color, contrast and / or brightness compared to the scale segments with which the current speed is displayed.
- FIG. 3 shows a schematic section through a further embodiment of a display device
- FIG. 4 shows a plan view of part of a display device according to FIG. 3;
- Figure 8 shows a detail of the display device shown in Figure 7.
- the display device described below serves to display two display sizes assigned to one another with the aid of scale segments.
- the display device shown here is a display of an automatic speed control.
- the display shows the current driving speed and, on the other hand, a set variable that can be programmed by the driver, namely the target speed.
- the sectional illustration shown in FIG. 1 shows a first embodiment of a display device 1, which shows two display sizes assigned to one another, namely the actual speed and the desired speed.
- Scale segments 3 and 5 are provided to represent the two display sizes.
- the first scale segment 3 is used, for example, to display the actual size, while the second scale segment 5 is used to display the desired size.
- the display device 1 has two lighting devices 7 and 9, of which the first lighting device 7 has the scale segments 3 and the second lighting device 9 is assigned to the scale segments 5.
- the first lighting tung ⁇ Rhein 7 can be realized by any tel Leuchtmit ⁇ , bei ⁇ pielswei ⁇ e by LED ' ⁇ , incandescent lamps, or Kaltkatodenfluore ⁇ zenslampen der ⁇ same.
- the illuminants emit light which passes through a light disk 11 and strikes a display surface 13, for example also a dial of a multiple display device of a vehicle.
- the display area 13 is provided with openings which form the scale segments 3 and 5.
- the first scale segments 3 are thus illuminated by the first lighting device 7.
- the second lighting device 9 has individual lighting elements 15, each of which is assigned to a single scale segment 5.
- the scale segments 5 are part of an accompanying scale, which serve to display the display size associated with the actual speed, namely the target speed.
- the set speed can be displayed by assigning a corresponding scale segment, for example scale segment 5 ', to display the set speed 60 km / h.
- the scale segments 3 can, for example, be backlit in white, while the scale segments 5 light up in a different color to indicate the set size or setpoint speed. As shown in FIG.
- the light beams of the individual lighting elements 15 are arranged in a light shaft 19 which is optically separated from the first lighting device 7 and which can have, for example, a light guiding element 21 through which the light emitting element 15 emanates Light, as shown by arrows, is passed on to scale segment 5.
- the individual lighting element 15 can be realized as a light-emitting diode (LED) or by a suitable other small light source.
- LED light-emitting diode
- FIG. 3 shows a further embodiment of a display device.
- device 10 which in turn has two lighting devices 7 and 9. Identical parts are provided with the same reference numerals, so that reference can be made to the description given for FIG. 1.
- the first lighting device 7 corresponds to that explained with reference to FIG. 1. It has the task of illuminating a series of scale segments 3 which serve to display a first display size, for example the actual speed.
- the scale segments 3 are in turn realized by cutouts in a display area 13 which is underlaid with a light-emitting disk 11.
- the light disk 11 and the dial or the display surface 13 of the display device 10 are used by a holding and light shaft device 23 which, like the lighting device 7-, is arranged on a base plate 25.
- the second lighting device 9 is provided, which in turn comprises single lighting elements 15, each of which is assigned to a single scale segment. It shows that the individual lighting elements 15 do not illuminate separate scale segments 5 here. Rather, the light rays of the individual lighting elements 15 indicated by arrows fall through the scale segments 3 and can thus be perceived by an observer or a driver.
- FIG. 4 shows a plan view of a section of the display device 10. It is characteristic that a single scale segment group is provided here, which is formed by the scale segments 3. Numbers 17 can also be provided here, which serve to read both the actual and the desired speed.
- the scale formed by the scale segments 3 is backlit by the first lighting device 7, for example white.
- a single scale segment for example the scale segment 3 ', is additionally illuminated by the associated individual lighting element 15, so that there is an increased brightness, but preferably a different color than that of the other scale segments 3 is given.
- the driver can thus read the set size or the set speed at a glance without having to look at a speed display other than that desired, as in conventional devices.
- the current speed is on the scale segments 3 displayed with the help of a pointer, not shown here.
- FIG. 5 shows a further embodiment of the display device 100, which is distinguished by the fact that only a single lighting device 7 is provided, which illuminates scale segments 3 provided in a display area 13 and realized as cutouts. Lines indicate that the entire display area 13 is penetrated by the light, so that backlighting is implemented by the lighting device 7.
- the lighting device 7 is accommodated in a light shaft 190 acting as a reflector box, the inner surface of which can, for example, have a reflective coating.
- the lighting device 7 is implemented in a known manner, as explained with reference to FIG. 1.
- a liquid crystal layer 27 Below the display surface 13 serving as the dial there is a liquid crystal layer 27, each of which has a switching device under a scale segment 3, which is implemented by switching fields 29.
- the switch panels 29 serve as transit switches. They therefore influence the permeability of the liquid-crystal layer 27 in the area of the scale segments 3. While the light from the lighting device 7 can penetrate the display area 13 unhindered when the switching field is switched off, shadowing takes place when the switching field 29 is switched on.
- FIG. 6 which shows a top view of part of the display device 100, shows that a scale field 3 'appears darker than the other scale segments 3 of the display device 100.
- the same parts in FIGS. 5 and 6 are provided with the same reference numbers, so that their detailed description can be dispensed with.
- the lighting device 7 shown in dashed lines can be straight and that the scale segments 3 can be curved along a circular line.
- the embodiment of the display device 1000 shown in FIGS. 7 and 8 is distinguished by the fact that the lighting device device 7 can be realized relatively cheaply, since here no curved light sources have to be used, as is necessary in the exemplary embodiment which was explained with reference to FIG. 5.
- FIG. 8 shows that the light exit area of the light guide device 33 appears dark when the associated switching fields 29 are activated. It is therefore possible to implement a display device 1000 which has a continuous row of scale segments 3, at least one of which appears optically separated by pressing a set key. It is possible to darken all of the scale segments 3 of a display device 1000 and to make only a single one appear bright by deactivating the associated control panel in order to make a desired setpoint value of the speed easily recognizable. The opposite implementation may also be possible: only the desired scale segment of the target speed selected by the driver is darkened, while all other scale segments appear bright. Finally, it is also possible to use the switch fields to lift off, ie darken or lighten, all of the scale segments present at the desired speed.
- the exemplary embodiments of the display devices 100 and 1000 which are explained with reference to FIGS. 5 to 8, only have a single lighting device. Accordingly, the scales of these display devices 100 and 1000 have a single scale, which is realized by scale segments 3. Within the series of scale segments, individual ones can be highlighted by a deviation in the brightness. The brightness differences are set by switching fields 29 which are assigned to each individual scale segment 3.
- the switching fields 29 can - as shown in FIG. 5 - be directly assigned to a scale segment 3 or - as explained with reference to FIG. 7 - a light guide device 33 which supplies the light coming from the lighting device 7 to a scale segment 3.
