Patent ID: 7737934

Claim:
A driving method for activating an optical self-compensated birefringence mode liquid crystal device having plural pixel structures, plural substrates and a liquid crystal layer sandwiched between said plural substrates, wherein each of said plural pixel structures comprises a first electrode having a vertical edge and an opening, a second electrode having a plurality of vertical edges, and a pixel electrode, said edges of said first electrode and said second electrode are complementary to each other, said second electrode has a bend being a polygon with one shape selected from a group consisting of a triangle, a rectangle, an L shape, a stair shape and a meander shape, said opening contains said bend, and said driving method comprises steps of: providing a horizontal space between said vertical edge of said first electrode and a respective one of said plurality of vertical edges of said second electrode being the closest one to said vertical edge of said first electrode on one of said plural substrates to make said first and said second electrodes be separated from each other in a horizontal direction; providing a first potential difference between said first electrode and said second electrode to generate a first electric field; and performing an initialization process from a bend of said second electrode to transitioning an alignment state of said liquid crystal layer from a non-display alignment state to a display alignment state by said first electric field.
