STRUCTURED POLMER SUBSTRATE FOR INK-JET PRINTING OF AN OLED MATRIX

摘要

The present invention provides a matrix substrate for controlling liquids printed on the substrate and a method of fabrication of such. According to the invention, a substrate holding a matrix of pixels for receiving and holding printed liquids is fabricated in a deformable and flexible polymeric material which allows for raised structures (barriers) separating the pixels to be formed in the substrate material itself. This renders possible a number of new methods of fabrication for the fabrication of matrix substrates, e.g. for use in polyLED displays. The materials and methods of fabrication according to the invention further remove a number of limitations in the freedom of design known from materials and methods of fabrication according to the prior art. This leads to the possibility of barrier profiles with overhanging structures, improved resolution and new dimension ranges.
