Invited; TFT circuits for driving sensors and actuators on flat panels
Conference Dates
May 15-18, 2023
Abstract
Thin-film transistor (TFT) technology is critical for the fabrication of modern flat panel displays. TFT technology can be used in many more emerging applications. In previous work, we demonstrated the capabilities of a-IGZO TFTs in the fields of NFC tags, temperature sensor readout, touch screen communication, active pixel X-ray detectors, fingerprint detectors, memory blocks and microprocessors [1]. Amorphous oxide semiconductors like a-IGZO have two main limitations, however: only n-type devices exist, and the mobility is quite limited. In addition, in the past, no stable and reliable TFT FAB technology was available. In this paper, we improve on these previous demonstrations by using LTPS transistors, available as fab service [2,3]
