An active artificial iris controlled by a 25-μW flexible thin-film driver
2016 Edition, December 1, 2016 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

We show an active artificial iris based on solely thin-film components, wherein several LCD elements are controlled a metal-oxide TFT and by powered by thin-film photovoltaics (TFPV). Key aspects for the...

A High-Reliability Carry-Free Gate Driver for Flexible Displays Using a-IGZO TFTs
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Most thin-film transistor (TFT) gate drivers integrated on the display panel use the carry signals between the stages. In our previous works, we found that these carry-type gate drivers are subject to the reliability problem in a flexible display, since the...

High-Resolution Flexible AMOLED Display Integrating Gate Driver by Metal–Oxide TFTs
2018 Edition, Volume 39, November 1, 2018 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

This letter proposes a high-resolution [200 (RGB) * 600, 282 PPI) flexible active matrix organic light emitting display (AMOLED) integrating a new gate driver, of which the substrate is a polyimide material. Flexible In-Zn-O thin-film...

Process Design Kit and Design Automation for Flexible Hybrid Electronics
2019 Edition, April 1, 2019 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

High-performance low-cost flexible hybrid electronics (FHE) are desirable for applications such as internet of things (IoT) and wearable electronics. Carbon-nanotube (CNT) thin-film transistor (TFT) is a promising candidate for high-performance FHE, because of its high...

A High-Reliability Carry-Free Gate Driver for Flexible Displays Using a-IGZO TFTs
2018 Edition, Volume 65, August 1, 2018 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Most thin-film transistor (TFT) gate drivers integrated on the display panel use the carry signals between the stages. In our previous works, we found that these carry-type gate drivers are subject to the reliability problem in a flexible display, since the...

Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

The maturity of metal-oxide thin-film transistors (TFT) highlights opportunities to develop robust and low-cost electronics on flexible and stretchable substrates over large area in an industry-compatible technology. Internet-of-Everything applications with sensor nodes...

Amorphous-InGaZnO Thin-Film Transistors Operating Beyond 1 GHz Achieved by Optimizing the Channel and Gate Dimensions
Volume PP - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Amorphous indium-gallium-zinc oxide (a-InGaZnO or a-IGZO) has already started replacing amorphous silicon in backplane driver transistors for large-area displays. However, hardly any progress has been made to commercialize a-IGZO for electronic circuit applications...

Active surface shaping for artificial skins
2011 Edition, October 1, 2011 - IEEE - Institute of Electrical and Electronics Engineers, Inc.

Artificial skins exhibit different mechanical properties in compare to natural skins. This drawback makes physical interaction with artificial skins to be different from natural skin. Increasing the performance of the artificial skins for robotic hands and medical applications...
