An organic light emitting diode display is provided. In combination the signal processor is operationally situated between the vehicle mounted electronic device and the electronic media storage device. In readout, the switch circuits are turned on to read memory cell data to the sense amplifiers while the sense amplifiers are turned off, and the switch circuits are then turned off once. The motor unit is configured to be releasably connected to the base unit. A control surface located adjacent to the cutting edge in the forward region enables a precise control of the cutter. Dither pickoff signals are sampled during the dither input signal cycle at points where error is more prevalent in the dither pickoff signal.
