Opis projektu
Organic and large-area electronics, visualisation and display systems
The aim of this project is to research the materials, processing technology (including encapsulation) and substrate handling procedures to make organic light-emitting color displays (OLED) on very thin plastic foils and driven by organic thin-film driving transistors. This proposal builds further on FLEXIDIS, where (mechanically flexible) active matrix backplanes were researched. The new project considers to advance the state of the art for a particular class of displays, namely high-information OLED displays for nomadic applications that can be rolled up repeatedly to a radius of 1 cm. The organic TFT backplane and OLED layers are processed directly on plastic substrates. The rationale for this choice is:- A rollable, full-color, video-speed OLED display is the ultimate visual experience provider for next-generation portable, lightweight applications;- Rollability requires the substrate to be plastic with thickness of 100 micron or less;- Direct fabrication onto plastic substrates is undoubtedly most cost-effective in the longer term;- OLEDs on plastic substrates have been shown, but further research is needed to encapsulate OLEDs (and the underlying OTFTs) in a flexible, rollable application;- Organic transistors are highly compatible with plastic substrates, because of their low processing temperatures and similarity in thermal expansion coefficients. Furthermore, Europe is frontrunner in this new technology. This in contrast with amorphous and polycrystalline silicon, which are dominated by the Far East;- Preliminary results indicate that the bias stress instability of organic transistors may be less severe than for amorphous silicon, making them particularly attractive for OLED displays that are current-driven.The consortium consists of the minimum set of needed partners for this ambitious research plan: three research institutes with world state of the art OTFT and OLED technologies and an SME end user for manufacturing rollable displays.
