Claim Text:
1. A tri-state liquid crystal display panel, comprising: a first substrate; an insulation layer, disposed on the first substrate; a second substrate, disposed to face the first substrate; a liquid crystal layer, disposed between the first substrate and the second substrate; a first polarizer, disposed on the first substrate, wherein the first polarizer has a first polarization axis; a second polarizer, disposed on the second substrate, wherein the second polarizer has a second polarization axis; a first electrode, disposed between the first substrate and the insulation layer, wherein the first electrode receives a first voltage; a second electrode, disposed between the second substrate and the liquid crystal layer, wherein the second electrode receives a second voltage; a third patterned electrode, disposed between the insulation layer and the liquid crystal layer, wherein the third patterned electrode receives a third voltage; a fourth patterned electrode, disposed between the insulation layer and the liquid crystal layer, wherein the fourth patterned electrode receives a fourth voltage; a first active switching device connecting to a first data line and the first electrode, and providing the first voltage to the first electrode; a second active switching device connecting to a second data line and the third patterned electrode, and providing the third voltage to the third patterned electrode; and and a third active switching device connecting to a third data line and the fourth electrode, and providing the third patterned voltage to the fourth patterned electrode; wherein the tri-state liquid crystal display panel provides a first display mode, a second display mode, and a third display mode by manipulating the first voltage, the second voltage, the third voltage, and the fourth voltage independently.
