Abstract
A pixel circuit arranged in an electrophoretic display is provided. The pixel circuit includes a first transistor, a storage capacitor, and an output stage. A first terminal of the first transistor is coupled to a data line. A control terminal of the first transistor is coupled to a scan line. The storage capacitor is coupled to a second terminal of the first transistor. The output stage is coupled to the second terminal of the first transistor and the storage capacitor. The output stage receives a first voltage and a second voltage. The output stage selectively outputs the first voltage or the second voltage to a pixel electrode of the electrophoretic display according to a data voltage provided by the storage capacitor.
