Publication number: 20150351207Abstract: This disclosure provides apparatus and methods for mitigating electrostatic discharge (ESD) in display devices. In one aspect, a display device includes an encapsulation substrates having an anti-static coating on one or more of surfaces of the encapsulation substrate. The display devices can include transparent substrates having display elements thereon such that the encapsulation substrate that covers the display elements. The anti-static coating on one or more surfaces of the encapsulation substrate can dissipate charge that may build up during fabrication or operation of the display device. The anti-static coating can be conductive and transparent, with examples of such coatings including transparent conducting oxides (TCOs), thin metal films, thin carbon films, and networks of conductive nanostructures.Type: ApplicationFiled: May 29, 2014Publication date: December 3, 2015Applicant: QUALCOMM MEMS Technologies, Inc.Inventors: Ming-Hau Tung, Nassim Khonsari, Edward Keat Leem Chan, Ion Bita, William J. Cummings, Alan G. Lewis

Publication number: 20140177188Abstract: This disclosure provides systems, methods and apparatus for packaging of dissimilar devices using electromagnetic radiation from a laser. In one aspect, an apparatus can include a first substrate, a second substrate, and a first device and a second device disposed on the second substrate. A first metal ring on the first substrate contacts a second metal ring on a second substrate, and is heated by a first electromagnetic radiation from a laser to enclose a first cavity containing the first device. A third metal ring on the first substrate contacts a fourth metal ring on the second substrate, and is heated by a second electromagnetic radiation to enclose a second cavity containing the second device. Enclosing the first cavity may be performed under a first atmosphere, and the enclosing the second cavity may be performed under a second, different atmosphere.Type: ApplicationFiled: December 26, 2012Publication date: June 26, 2014Applicant: QUALCOMM MEMS TECHNOLOGIES, INC.Inventors: Philip Jason Stephanou, Ravindra V.

Patent number: 8310758Abstract: A static interferometric image device including a plurality of solidified liquid layers is formed over a substrate by an inkjet process such that the layers are lateral to one another. In some embodiments, the substrate includes pre-defined cavities, and the liquid layers are formed in the cavities. In other embodiments, the substrate includes a substantially planar, stepped, or continuously transitioning surface, and the solidified liquid layers are formed on the surface. Optical fillers or spacers are provided for defining interferometric gaps between absorbers and reflectors in the display device, based at least partially on an image that the display device is designed to display.Type: GrantFiled: August 11, 2011Date of Patent: November 13, 2012Assignee: Qualcomm Mems Technologies, Inc.Inventors: Mark W. Miles, Brian W. Arbuckle, Ion Bita, Manish Kothari, Patrick F. Brinkley, Gang Xu, Nassim Khonsari, Jonathan C. Griffiths

Patent number: 7826127Abstract: A microelectromechanical systems device having a transparent substrate joined to a planar backplate with a raised perimeter structure forming a recessed cavity or cell. The raised perimeter structure is formed by applying a first layer around the peripheral area of the backplate to form a recessed cell. A second layer is applied over the first layer. The first layer is thicker than the second layer. The thicker layer comprises a viscous material. A second layer is a thinner adhesive layer, and is applied over the thicker layer to join the backplate to the transparent substrate to encapsulate the microelectromechanical systems device formed on the transparent substrate.Type: GrantFiled: June 20, 2007Date of Patent: November 2, 2010Assignee: QUALCOMM MEMS Technologies, Inc.Inventors: Nassim Khonsari, Clarence Chui
