(Invited) Oxide TFT Applications: Principles and Challenges

Abstract

Oxide thin film transistors are emerging devices in high-speed, low- power active matrix displays. There are many other applications of this kind of device. The author analyzed these applications and categorized TFTs into three functions: as a control or readout unit for the attached device, as a switching device in circuits, and as a functional element itself in sensors. Examples on each function are shown and discussed. Future applications and challenges on oxide TFTs are presented.

Integrated Water-Level Sensor Using Thin-Film Transistor Technology

“…These TFTs are commonly integrated with TFTs on a glass substrate, forming an essential component of the display system. , Furthermore, TFTs have demonstrated their versatility in the development of diverse sensor types, including photo, fingerprint, temperature, gas, infrared (IR), and ultraviolet (UV) sensors. This is attributable to their compact form factor, energy efficiency, and scalability, making TFTs an ideal choice for sensor applications requiring miniaturization, low power consumption, and adaptability. − Consequently, the significance of TFTs is steadily rising in the realm of emerging technologies, notably, flexible electronics, medical devices, and wearable technology. Their distinctive properties offer new possibilities for innovation and growth. , …”
