A device for controlling current useful for driving an organic light emitting diode (OLED) is disclosed which comprises a driver further comprising a switching circuit and a capacitor operatively connected to the switching circuit. The capacitor serves to maintain V<SUB>GS </SUB>for at least one component of the switching circuit. During operation of an exemplary embodiment, current to a pixel may be controlled by providing a sampling stage, during which the capacitor may be charged and/or discharged; providing a data current outputting stage during which summed current from each switching circuit may be provided to the pixel; and providing a pixel current reproducing stage during which each pixel is allowed to emit light in the presence of current in the data line. It is emphasized that this abstract is provided to comply with the rules requiring an abstract which will allow a searcher or other reader to quickly ascertain the subject matter of the technical disclosure. It is submitted with the understanding that it will not be used to interpret or limit the scope or meaning of the claims.
