Description:

Mixed-mode simulation of simple multimodal transistor (MMT)-based pixel circuits demonstrate the viability of LTPS-only implementations for low refresh rate active-matrix emissive displays down to 1 Hz. The MMT allows >20x longer image retention TFT-based designs, owing to the reduced off-current of the MMT switch, the minimal dependence of MMT drain current on input voltage, and the low transconductance of the MMT.
