报告题目二:Proving Scalability of Fully Roll-to-Roll Gravure Printed Carbon Nanotube Based Active Matrix Backplanes for Smart Sensor Arrays and Digital Paper(No. PSLAB204-PS2015-07)

报告内容摘要:

  Over the last decade, roll-to-roll (R2R) printing has been pursued with the expectation of developing a commercially viable, high throughput technology to manufacture flexible, disposable and inexpensive printed electronics. However, in recent years, pessimism has emerged due to the barriers faced when attempting to fabricate and integrate thin film transistors (TFT) using R2R printing. In this presentation, we will report for the first time, 11 × 11, 20 × 20 and 40 × 40 TFT based active matrix backplanes with 9.3 dpi (dots per inch) resolution obtained using a fully R2R gravure printingprocess.Using single walled carbon nanotubes(SWCNT) as the semiconducting layer and poly(ethylene terephthalate) (PET) as the substrate we obtained a 99 % device yield and extracted the scalability factors needed for afeasible manufacturingprocess.  Smart sensor arraysor digital paper (signage)can be obtained bylaminating a pressure sensitive rubberor e-paper sheet to the TFT backplane. The R2R gravure printingprocess we have developed addresses several barriers in the fabrication and integration of printed TFTs, circumventing or surmounting challenges associated with the alignment ofsource-drain and gate electrodes, threshold voltage (Vth) shift, and overall device yield, proving that R2R printing is indeed a viable advanced manufacturing technology that can enable high throughput production of flexible, disposable and cutting edgeprinted electronics.

 Prof. Gyoujin Cho
 

 Gyoujin Cho received a Ph.D. degree from the University of Oklahoma, Norman, in 1995. In 1996, he joined the faculty of the Department of Chemical Engineering, Sunchon National University, Korea, and currently he is a faculty member in the Department of Printed Electronics Engineering, World Class University Program at Sunchon National University. Since 2002, he has focused his research on printed electronics and successfully demonstrated all-gravure printed 13.56 MHz RFID tags (4, 16, 32, and 96 bit). Recently, he is developing fully R2R gravure printed TFT backplane arrays for large area digital signage and wireless cyclic voltammetry tags as a platform for RF e-sensor based smart packaging.
