ABSTRACT:
A data current sample and hold circuit having an input terminal of a current source type and an output terminal of a current sink type. The sample and hold circuit includes a first transistor, a capacitor, and a plurality of switches, for sampling and holding the data current sunk to an output terminal of a data driver. When the sampled and held data current is applied to the data line, the data current is sunk to an output terminal of the sample and hold circuit. The sample and hold circuit is used together with a data driver having an output terminal of the current sink type.
