The pixel circuitry includes a storage element, a scan switch, a first control circuit and a second control circuit. The scan switch delivers a pixel signal to the storage element in response to a scan signal during a frame period.

The first control circuit selectively provides a reference voltage to one of the first and the second terminals of the storage element. The second control circuit selectively connects a pixel electrode to one of the first and the second terminals of the storage element. Under the control of the first and the second control circuits, the polarity of the pixel signal stored in the storage element can be changed by adjusting two terminal voltages of the storage element.
