Contrary to conventional design principles, current-driven pixel drivers based on source-gated transistors (SGTs) achieve their optimal drive current and speed with a deliberate 5–10- $\mu \text{m}$ gate–source overlap. Total pixel circuit area need not increase, as the additional device area can be compensated by reducing the pixel storage capacitor. The numerical simulations demonstrate the viability of SGTs for emissive pixel drivers and high gain, low power, and robust circuits for emerging sensor arrays.
