Patent number: 8062984Abstract: A method of fabricating an electronic device, the device including a plurality of layers on a substrate, the layers including an upper conductive layer and at least one patterned underlying layer between said conductive layer and said substrate. The method includes patterning said underlying layer, and patterning said upper conductive layer by laser ablation using a stepwise process in which successive areas of said upper conductive layer are ablated by successively applied laser patterns. The successively applied laser patterns overlap one another in an overlap region. The method further includes configuring a said laser pattern and said patterned underlying layer with respect to one another such that in a said overlap region said patterned underlying layer is substantially undamaged by said stepwise laser ablation.Type: GrantFiled: August 31, 2006Date of Patent: November 22, 2011Assignee: Plastics Logic LimitedInventors: Paul A. Caln, Carl Hayton

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
