Novel Modeling of Correlation between Two-Dimensional Registers in Large-Area Multilayered Roll-to-Roll Printed Electronics

Abstract

We present and discuss theoretical techniques that considerably increase the power of dynamical LEED calculations, particularly i n the layer treatment of surfaces. Their wide applicability makes them especially suitable for surface structural determination. The layer doubling method is an efficient and accurate way of calculating reflectivities off a stack of identical atomic layers requiring only finite absorption for convergence. Layer summation over surface-induced sublattices avoids the repetition of lengthy summations when the surface has a different two-dimensional unit cell than the substrate. The exploitation of symmetry finally can give spectacular reductions in computing time.

A Decoupling Control Strategy for Multilayer Register System in Printed Electronic Equipment

“…Register errors directly reflect the register accuracy, including two kinds [2,3]: machine directional register errors and cross directional register errors. In general, cross directional register errors can be ignored because the lateral jitter of a moving web is very small.…”

Machine Directional Register System Modeling for Shaft-Less Drive Gravure Printing Machines

“…The CDR errors are controlled by the lateral motion of printing rollers, which is greatly different from the control of MDR errors. In addition, initial works of modeling and control in correlation between MDR and CDR errors were researched in [10,11]. However, the in-depth research on the MDR system model based on shaft-less drive mode is still not enough in gravure printing machines.…”
