10‐4: Late‐News Paper: Precise Compensation of Device Variability in IGZO‐based Ferroelectric Thin‐Film Transistors for Enhanced Transparent Display Performance

We demonstrate the compensation of device‐to‐device variation in threshold voltage using programmable ferroelectric indium‐gallium‐zinc‐oxide thin‐film transistors. Furthermore, degradationinduced threshold voltage shift can be mitigated by programming, setting the characteristics back to their pris...

Description
Summary:We demonstrate the compensation of device‐to‐device variation in threshold voltage using programmable ferroelectric indium‐gallium‐zinc‐oxide thin‐film transistors. Furthermore, degradationinduced threshold voltage shift can be mitigated by programming, setting the characteristics back to their pristine state. This can be a promising alternative for the replacement of complex VT compensation circuits in display applications.
