Abstract
A gear stage display device of a vehicle is provided and includes a light-emitting unit that is configured to generate light with different brightnesses. In addition, a first brightness controller is connected to the light-emitting unit and is configured to adjust the light-emitting unit to a first brightness. A second brightness controller is connected in parallel to the first brightness controller and is configured to adjust the light-emitting unit to a second brightness. In response to receiving a brightness control signal and a gear stage selection signal, one of the first brightness controller and the second brightness controller is configured to adjust the light-emitting unit.
Claims18
A gear stage display device of a vehicle, comprising:
- a light-emitting unit configured to generate light with different brightnesses;
- a first brightness controller connected to the light-emitting unit and configured to adjust the light-emitting unit to a first brightness;
- and
- a second brightness controller connected in parallel to the first brightness controller and configured to adjust the light-emitting unit to a second brightness,
- wherein in response to receiving a brightness control signal and a gear stage selection signal, one of the first brightness controller and the second brightness controller is operated to adjust the light-emitting unit to one of the first brightness and the second brightness, and
- wherein the first brightness controller includes:
- a first switching device connected to the light-emitting unit;
- a first signal input terminal configured to receive a first brightness control signal and transmit the first brightness control signal to the first switching device;
- a second switching device connected to the first switching device;
- and a second signal input terminal configured to receive the gear stage selection signal and transmit the gear stage selection signal to the second switching device.
