TFTs are basic building blocks of display pixel circuits. For instance, they control the electrical charging of liquid crystal cells or produce the driving current of light-emitting diodes. Our group investigates both the fundamental operating mechanism and the technological application of emerging TFTs.
Organic, perovskite, quantum-dot and micro LEDs are the key drivers of display front plane technology. Our group uses advanced impedance spectroscopy to probe voltage and frequency sensitive capacitive and resistive features of LEDs and correlate these features with internal photon and carrier dynamics.
We use analytical equations, finite-element computer-aided design tools and integrated circuit simulators to model our display hardware. These models deepen our fundamental understanding, provide practical engineering guidelines and improve the accuracy of circuit and system performance prediction.
