In accordance with the present invention, there is provided a system and method for dark noise reduction in pulse width modulated displays. The control interface is configured to receive control information from one or more control sources coupled to it, and the local controller is further coupled to the at least one LED driver for controlling its operation by determining one or more LED driving parameters of the pulsed output power, based on the control information. A drive shaft extends through an opening in the spring bracket to drive the wheel assembly.
