Abstract
A system for removing dust from a touchscreen of a vehicle is provided. The system includes the touchscreen and a dust controller. The touchscreen includes at least one panel having a driving circuit and a sensing circuit, and a cover covering the at least one panel. The dust controller is operably connected to the touchscreen for applying a first voltage signal having a first polarity to at least one of the driving circuit and the sensing circuit for ionizing dust on the cover of the touchscreen, and then applying a second voltage signal having a second polarity opposite of the first polarity to at least one of the driving circuit and the sensing circuit to repel the ionized dust from the cover.

A system for removing dust from a touchscreen of a vehicle, the system comprising:
- a touchscreen including at least one panel having a driving circuit and a sensing circuit, and a cover covering the at least one panel;
- and
- a dust controller operably connected to the touchscreen for applying a first voltage signal having a first polarity to at least one of the driving circuit and the sensing circuit for ionizing dust on the cover of the touchscreen, and then applying a second voltage signal having a second polarity opposite of the first polarity to at least one of the driving circuit and the sensing circuit to repel the ionized dust from the cover.
A system for removing dust from a touchscreen of a vehicle, the system comprising:
- a touchscreen including at least one panel having a driving circuit and a sensing circuit, and a cover covering the at least one panel;
- a dust controller operably connected to the touchscreen for applying a first voltage signal having a first polarity to at least one of the driving circuit and the sensing circuit for ionizing dust on the cover of the touchscreen, and then applying a second voltage signal having a second polarity opposite of the first polarity to at least one of the driving circuit and the sensing circuit to repel the ionized dust from the cover;
- an occupant detector for determining whether an occupant is within the vehicle;
- and
- a controller in communication with the dust controller and the occupant detector, wherein the controller disables the dust controller upon detection by the occupant detector of an occupant within the vehicle.
A method of removing dust from a touchscreen of a vehicle, the touchscreen including at least one panel having a driving circuit and a sensing circuit, and a cover covering the at least one panel, the method comprising:
- determining whether an occupant is within the vehicle;
- and
- if it is determined that an occupant is not within the vehicle, applying a first voltage signal having a first polarity to at least one of the driving circuit and the sensing circuit for ionizing dust on the cover of the touchscreen, and then applying a second voltage signal having a second polarity opposite of the first polarity to at least one of the driving circuit and the sensing circuit to repel the ionized dust from the cover.
