Abstract:
1. A patterning method for manufacturing a device including a first electrode, a second electrode, an insulator material positioned between the first and second electrodes, and a first light emissive polymer material positioned between the first and second electrodes so that a current flows between the first and second electrodes via the first light emissive polymer material, the insulator material being a non-emissive insulator polymer material and the first light emissive polymer material being surrounded by a first ridge area of the insulator material, the method comprising: forming the insulator material on the first electrode; discharging a first droplet onto a first portion of the insulator material, the first droplet including the first light emissive polymer material, the first droplet dissolving the first portion of the insulator material, the insulator material and the first light emissive polymer material being separated by a phase separation phenomenon such that the first light emissive polymer material is surrounded by the first ridge area of the insulator material after the phase separation phenomenon occurs; and forming a second electrode on the insulator material and the first light emissive polymer material.
