We have studied ink-jet printing method for patterning conductive line on flexible plastic substrates. Synthesized silver nano-particles of ${\sim}$20nm were used for the conductive ink and the printed patterns exhibit a smooth line whose linewidth is below 100 ${\mu}m$. This ink-jet printing technique can be applied to flexible displays and electronics.

True electronic paper displays are being enabled by the development of two core technologies - plastic electronics for display backplanes and electrophoretic ink for use as the imaging layer. Electrophoretic ink developed by E Ink Corporation continues to advance performance along with parallel technology breakthroughs in flexible TFT backplanes. An overview of these advances in the ink imaging material will be discussed with special emphasis of the expected impact on the emerging flexible display applications.

Organic light emitting transistors (OLET) which are vertically combined with the organic static induction transistor (OSIT) and organic light emitting diode (OLED) are fabricated and the device characteristics are investigated. High luminance modulations by relatively low gate voltages are obtained. In order to realize the flexible electronic circuits and displays, we have fabricated OSIT on plastic substrates. The OSIT fabricated on plastic substrate show almost same characteristics comparing with those of nonflexible OSIT on glass substrate. The OLET described here is a suitable element for flexible sheet displays.

A buffer layer consisting of $SiO_x/Ta/Ti$ has been developed in order to overcome the adhesion and stress problems between poly-Si film and mica. Polycrystalline silicon thin film transistor was successfully fabricated on the mica and transferred to a flexible plastic substrate.

We have investigated printing techniques for processing organic light-emitting diodes (OLEDs). We succeeded to gravure print uniform organic thin films as well as screen print low work function cathode for OLED structure. Furthermore, by using roll-to-roll manufacturing methods, we have been able to fabricate all-printed flexible OLED demonstrator.

Sub 10-nm thick of Si plate is simulated with the software for Nanowire Field Effect Transistor (FET) device simulation. With usual single crystal Si technology, it is difficult to realize flexible electronic devices. Here, we suggest a FET device based on thinned Si layer. The simulation implied a practical limitation of the Si plate thickness for flexible devices as 2 nm. With around this thickness, Si plate may have much flexibility than existing bulk MOSFETs.

We investigated the crystalline and electrical properties of ZnO thin films for transparent electrode as a function of the oxygen pressures during the deposition. The ZnO thin films were deposited on a flexible teflon substrates by the pulsed laser deposition. From the X-ray diffraction, ZnO films showed c axis oriented ZnO(0002) crystal structure. The FWHM (full width at half maximum) values decreased from $0.51^{\circ}\;to\;0.34^{\circ}$ as the oxygen pressure increased from 0.1 mTorr to 10.0 mTorr showing the improvement of crystallinity. The resistivity and hall mobility of ZnO film deposited at the oxgen pressure of 0.1 mTorr at $200^{\circ}C$ was about $5\times10^{-4}\Omega{\cdot}cm\;and\;20cm^2/V{\cdot}s$, respectively. The optical transmittance of the ZnO films on flexible teflon substrate was found to be above $85\%$.
