摘要

A circuit for converting voltage levels for a liquid crystal display panel that comprises a signal including a first state of a first voltage level and a second state of a second voltage level, a first power supply providing the first voltage level, a first high-voltage transistor including a gate electrode coupled to the first power supply, a first electrode receiving the signal, and a second electrode coupled to a node, a second power supply providing a third voltage level, and a second high-voltage transistor including a first electrode coupled to the second power supply and a second electrode coupled to the node, wherein a voltage level at the node is pulled to approximately the third voltage level in response to the first state of the signal, and pulled to approximately the second voltage level in response to the second state of the signal.
