Electrical characterization of metal electrodes deposited on flexible polydimethylsiloxane substrates for folding test

Abstract

The objective of this study is to present an electrical characterization of metal electrodes deposited on flexible substrates for folding test. In order to quantize folding conditions, flexiblecharacteristic inspection system (FCIS) [1] for folding function is utilized to control radii of curvature of the flexible substrates. As a result, the new technique successfully measures electrical characteristics of flexible polydimethylsiloxane (PDMS)/gold electrodes for analysis during the 0/m to 200/m curvature folding cycles. Inspection results of folding characteristics depicted on flexible displays help a designer or maker of flexible displays design useful and comfortable flexible electronic products.
