detailed description

FIG. 1 schematically shows an embodiment of a display device 6 according to the invention of a motor vehicle with two dials 1 for displaying the vehicle's speed and engine speed. The display device 6 is connected to a control device 5 which generates a control signal 5 a for controlling at least the two dials 1 and the reading markings 3 associated with the dials, for example pointer elements. With the aid of the control signal, the illumination of the dial or the dial part and the reading marks 3 can be switched on, the brightness of the dial 1 , the parts of the dial and the reading marks 3 can be changed and the movement of the reading marks 3 can additionally be controlled. In this exemplary embodiment, the control device 5 is designed in such a way that upon receipt of the start signal 4 a of the starter device 4 of the vehicle, a control signal 5 a is generated for generating a wake-up scene of the display device 6 . A change in the visually perceivable properties of the dial 1 and/or a change in the visually perceivable properties of the reading mark 3 is effected during this wake-up scenario.

Possible wake-up scenarios of the display device 6 are shown in FIGS. 2 a to 2 d. When starting the vehicle, the illumination of the dial 1 and the reading marking 3 are brightened or their illumination is switched on. The illumination of scale number 2 is not switched on or its brightness is not changed. The scale number 2 is then not or only very weakly illuminated ( FIG. 2 a ). In a second step or simultaneously with the illumination of the dial 1 or the intensification of the illumination, the reading mark or pointer 3 is moved along the dial 1 at a defined speed, wherein as the reading mark 3 moves from the initial position A along the The movement increases the brightness of the illuminated dial 1 , which preferably takes place steplessly. With the movement of reading mark 3 additionally a defined scale number 2 is switched on. If the reading mark 3 has reached a defined deflection position B, preferably the end position of the dial 1 and not only the dial 1 but also the numerals 2 have reached their running brightness (Fig. 2c), the reading marking 3 returns to its initial position A, the dial The resulting perceivable properties of 1 and scale number 2 are maintained and the operating and/or functional states, such as cooling water temperature, engine oil temperature, display of speed, function of the airbag and/or ABS are displayed in perceivable properties show.
