Patent ID: 8482497

Claim:
A switch matrix of a display device, comprising M*N MEMS switches, wherein M is the number of rows and N is the number of columns, and MEMS switches in each row are controlled by a corresponding row drive signal to output respective column data signals, wherein each of the MEMS switches comprises: a first electrode comprising a first terminal to which a column data signal is input and a second terminal, and a first plate insulated from the first terminal and the second terminal; and a second electrode comprising an electrical conductor and a second plate insulated from the electrical conductor, wherein the row drive signal controls relative movement of the first electrode and the second electrode so that the electrical conductor of the second electrode connects the first terminal and the second terminal of the first electrode, wherein the first electrode is formed on a base which comprises a substrate and a first insulation layer arranged on a surface of the substrate, the first insulation layer having an opening, and the first plate of the first electrode is formed on the interface of the first insulation layer of the base, and the first terminal and the second terminal are formed respectively on sides of the opening of the first insulation layer of the base, and wherein the second plate of the second electrode is arranged facing the first plate of the first electrode; the second electrode further comprises a second insulation layer which is formed on the surface of the second plate facing the first plate and exposes the surface of the second plate facing the first plate; the second insulation layer is provided with an opening arranged to correspond to the opening of the first insulation layer; and the electrical conductor is formed in the opening of the second insulation layer.
