Abstract

A motor vehicle key for locking or unlocking a door of a motor vehicle or for operating the motor vehicle includes a display configuration for displaying information which relates to the motor vehicle or for displaying the function of an operator control element of the motor vehicle key. The display configuration includes at least a MEMS display, a cholesteric display and/or an electrophoretic display.

Claims

1. In combination with a motor vehicle having a vehicle door, a motor vehicle key configuration, comprising:

a motor vehicle key configured for a function selected from the group consisting of locking the vehicle door, unlocking the vehicle door and operating the motor vehicle;

said motor vehicle key including an operator control element and a display configuration for displaying information selected from the group consisting of information related to the motor vehicle and information indicating a function of said operator control element; and

said display configuration including at least a display selected from the group consisting of a bistable MEMS display, a cholesteric display and an electrophoretic display.

2. The vehicle key configuration according to claim 1, wherein said display configuration has no light source for actively emitting light disposed underneath said display.

3. The vehicle key configuration according to claim 1, wherein said display is a bistable display.

4. The vehicle key configuration according to claim 1, wherein said display is a reflective display.

5. The vehicle key configuration according to claim 1, wherein said display is a pigment-free display.

6. In combination with a motor vehicle having a vehicle door, a motor vehicle key configuration, comprising:

a motor vehicle key configured for a function selected from the group consisting of locking the vehicle door, unlocking the vehicle door and operating the motor vehicle;

said motor vehicle key including an operator control element and a display configuration for displaying information selected from the group consisting of information related to the motor vehicle and information indicating a function of said operator control element; and

said display configuration including at least a quasistatic reflective display.

7. The vehicle key configuration according to claim 6, wherein said quasistatic reflective display is a pigment-free display.

8. The vehicle key configuration according to claim 6, wherein said quasistatic reflective display is a bistable display.

9. In combination with a motor vehicle having a vehicle door, a motor vehicle key configuration, comprising:

a motor vehicle key configured for a function selected from the group consisting of locking the vehicle door, unlocking the vehicle door and operating the motor vehicle;

said motor vehicle key including an operator control element and a display configuration for displaying information selected from the group consisting of information related to the motor vehicle and information indicating a function of said operator control element; and

said display configuration including at least a bistable display.
