Simulation of organic light-emitting diode-based inkjet printing using a piezoelectric fluid structural interaction model
Abstract Organic/quantum dot light-emitting diode displays have recently been manufactured using inkjet printers, which require stable ink drops and strict control during the printing process. Combining Ansys Fluent and Ansys Mechanical simulations, this research establishes the conditions that stab...

| description | Abstract Organic/quantum dot light-emitting diode displays have recently been manufactured using inkjet printers, which require stable ink drops and strict control during the printing process. Combining Ansys Fluent and Ansys Mechanical simulations, this research establishes the conditions that stabilize the ink droplets. The feasibility of this approach is verified through a jetting simulation of Newtonian fluids with almost constant viscosity and a comparison of the simulation and experimental results. Then, a commercial non-Newtonian ink with a shear-rate-dependent viscosity is simulated, and the simulation and experimental results are again compared. The study then evaluates why the experimental and simulation outcomes of non-Newtonian fluids differ under the same voltage conditions. Besides finding the stable drop conditions, the performed inkjet simulations reveal the pressure changes in the inkjet nozzle. |
