Abstract

The idea of having flexible, very thin, light, low power and even low cost display devices implemented using new materials and technologies is very exciting. Nowadays we can talk about more than just concepts, such devices exist, and they are part of an emerging concept: FOLAE (Flexible Organic and Large Area Electronics). Among the advantages of electrochromic devices are the low power consumption (they are non-emissive, i.e. passive) and the aspect like ink on paper with good viewing angle. Some studies are still necessary for further development, before proper performances are met and the functional behavior can be predicted. This paper presents the results of the research activity conducted to develop electric characterization platform for the organic electronics display devices, especially electrochromic displays, to permit a thorough study. The hardware part of platform permits the measuring of different electric and optical parameters. Charging/discharging a display element presents high interest for optimal driving circuitry. In this sense, the corresponding waveforms are presented. The contrast of the display is also measured for different operation conditions as driving voltage levels and duration. The effect of temperature on electrical and optical parameters (contrast) of the display will be also presented.
