Abstract
An LCD pixel includes a first conductive segment connected to a first bus, a first insulator segment on the first conductive segment, a second conductive segment on the first insulator segment, a liquid crystal material on the second conductive segment, a third conductive segment on the liquid crystal material, and a thin film transistor having a control terminal, a first power terminal and second power terminal connected to a second bus, a third bus and the second conductive segment, respectively. In response to application of a suitable signal on the second bus when reference voltages are present on the first bus and on the third conductive segment, and a voltage is applied to the third bus, the thin film transistor is operative for charging a capacitor formed by the first conductive segment, the first insulator segment and the second conductive segment and for activating the liquid crystal material.
