Publication number: 20110316930Abstract: A modular micro-fluid ejection device includes a carrier frame supporting pluralities of micro-fluid ejection modules. Each of the modules has a plate of nozzles defining a plane. Adjacent nozzle plates are substantially coplanar and registered with one another across the entirety of the carrier frame. Methods to mount the modules to the frame include, first, temporarily mounting one module and then another, and then permanently mounting both with a durable adhesive. Manufacturing systems include suction devices to hold a first module in place on a fixture while later modules are suctioned and registered to each other. Once set in place, a carrier frame is commonly contacted to the modules and the suction to released. Adhesives between the frame and modules cause the modules to separate from the fixture and transfer to the frame. All remain properly registered upon transfer.Type: ApplicationFiled: June 29, 2010Publication date: December 29, 2011Inventors: Richard E. Corley, Michael J. Dixon, Jiandong Fang, Jeanne Marie Saldanha Singh

Patent number: 7425795Abstract: This invention addresses how an end user can create an electroluminescent device (1, 31) using basic components obtained by the end user as retail items. The layers or subassemblies (15, 17) are created first. Then the layers are assembled to form a completed device customized as selected by the end user. The subassemblies may be created layer-by-layer by thermal inkjet. Elements used typically will be made by manufacturers and sold commercially separately. This encompasses the printing of conductive patterns for electroluminescence on paper. In one aspect a display has a main body that may be permanent and useful indefinitely, while a part carrying the conductive pattern defining the display is readily removed and is replaced by another such part on which a new conductive pattern is printed. For tight contact with the main body, the display provides releasable pressure. Air pockets are minimized with a thin layer of highly viscous dielectric liquid.Type: GrantFiled: August 23, 2005Date of Patent: September 16, 2008Assignee: Lexmark International, Inc.Inventors: Frank Edward Anderson, Michael John Dixon, James Paul Drummond, Bryan Dale McKinley, Amanda Kay Plakosh-Angeles, Jerry Randall Reed, Jeanne Marie Saldanha Singh, George Nelson Woolcott
