Abstract

The invention provides a display device based on a micro-electromechanical system (MEMS) light valve. The display device comprises a substrate, and an MEMS switch and the MEMS light valve which are arranged on the surface of the substrate, wherein the MEMS switch comprises a first electrode, a third electrode, and a second electrode which is arranged relative to the first electrode and the third electrode; the second electrode is provided with a contact protrusion relative to the third electrode; and when a potential difference exists between the first electrode and the second electrode, the second electrode approaches the third electrode under the action of an electrostatic force, so that the contact protrusion contacts the third electrode so as to control the MEMS light valve through the MEMS switch. The invention also provides a forming method for the display device based on the MEMS light valve. In the display device, the MEMS switch replaces a thin-film transistor (TFT) switch tocontrol a display signal of the display device; and the MEMS switch is simple in structure, so that a manufacturing process of the display device is simplified and the manufacturing cost of the display device is reduced.

Description
