In this paper, we study the electronic performance of the inkjet-printed electrochromic (EC) display which uses Poly (3,4-ethylenedioxythiophene) (PEDOT) doped with poly (styrenesulfonate) (PSS) as the active material, and extract its equivalent RC model. Results show that by charging PEDOT:PSS with 1.8V for averagely 10s, it can be switched from transparent (oxidation state) to blue (reduced state) and keeps the color for an average of 300s in the absence of energy supply, consuming much lower power than other flexible display technologies. However, it suffers from significant crosstalk effects in passive-matrix addressing and from performance variation as sample changes or time goes on. Based on the results, we design a programmable digital display driver with two different operation modes, and analyze the feasibility to integrate such display function in passive intelligent packaging systems. System simulation results prove it as a promising solution from evaluation of power budget and driving ability with printed interconnections and offchip conductors.
