Publication number: 20110095999Abstract: We describe an architecture for a large-area, touch-sensitive electronic document reading device which is able to tolerate bending. In broad terms, a control circuit board is mounted behind a flexible display structure in the housing and at respective points of attachment of first and second laminar connectors to the control circuit board each laminar connector has a plurality of electrical connections running along a longitudinal direction of the laminar connector and disposed alongside one another in a transverse direction across the laminar connector. At the respective points of attachment of the first and second laminar connectors to the control circuit board the longitudinal directions of the laminar connectors are aligned such that, when said device is flexed, a relative displacement in said longitudinal direction between said control circuit board and of said display structure can be tolerated without damage to the control electronics, touch sensitive display screen or connections therebetween.Type: ApplicationFiled: December 28, 2009Publication date: April 28, 2011Applicant: PLASTIC LOGIC LIMITEDInventor: Carl Hayton

Patent number: 7867686Abstract: A method for electroless plating of metal on a laser-patterned substrate. A substrate is provided on which both a thermal imaging layer and catalytic layer are deposited. On exposure to a laser beam, sufficient levels of radiation are converted to heat in the thermal imaging layer to render the exposed regions of the adjacent catalytic layer inactive. The laser-patterned substrate is then exposed to a reaction solution which initiates the growth of a metal film on the unexposed regions of the catalytic layer.Type: GrantFiled: February 10, 2005Date of Patent: January 11, 2011Assignees: Plastic Logic Limited, Conductive Inkjet Technology LimitedInventors: Michael J.
