Patent number: 9620732Abstract: A method of forming a light-emitting device comprises: forming patterned portions of precursor material over a substrate, the edges of the patterned portions defining sidewalls; performing a shaping control process on the patterned portions of precursor material to control the sidewall profile to reduce the angle the sidewalls of the precursor material make with the substrate to less than 15 degrees; selectively applying from solution a conductive coating onto the portions of shaped precursor material so as to form a plurality of first conducting contacts such that an upper surface of said conductive coating follows the sidewall profile of the precursor material; forming a light-emitting layer over the conductive contacts and substrate, and forming a plurality of second conducting contacts over the light-emitting layer. The precursor material may comprises an activator catalyst and the conductive coating comprises a metal selectively applied to the shaped precursor material by electroless plating.Type: GrantFiled: January 12, 2016Date of Patent: April 11, 2017Assignee: Cambridge Display Technology, Ltd.Inventors: Surama Malik, Colin Baker, Laurence Scullion

Patent number: 9054042Abstract: This invention generally relates to planarisation of a surface of a substrate. In an embodiment of planarising a surface region of a substrate, the substrate having a body on a portion of said surface region, the method comprises: modifying the wetability of a surface of said body with respect to a liquid planariser composition by providing a surface modifying layer such as a self-assembled monolayer thereon; and then depositing the liquid planariser composition on said substrate and said body such that the planariser composition wets said surface region, wherein said surface modifying layer determines a contact angle of said liquid planariser composition to said surface of said body such that the deposited liquid planariser composition is repelled from said surface of said body.Type: GrantFiled: March 21, 2012Date of Patent: June 9, 2015Assignee: CAMBRIDGE DISPLAY TECHNOLOGY LIMITEDInventors: Arne Fleissner, Surama Malik, Colin Baker, Laurence Scullion, Jeremy Burroughes
