Abstract
A bidirectional switch includes a pair of transistors, with each transistor including a source connected via a degeneration resistance to a common source control node, a gate connected to a common gate control node, a drain connected to a respective channel or gate line and to a charge storage node, respectively, and a clamp diode connected between the source and the gate. This forms a single charge transfer path between gate lines sequentially activated by a scan driver of an LCD panel, and implements a charge sharing technique for reducing power dissipation.
