Abstract
We propose a 7T2C micro‐LED pixel circuit which uses a multimodal transistor (MMT) as driver for compact pulseamplitude and pulse‐width modulation (PAM + PWM) functionality. The LTPS circuit exploits the MMT's ability to maintain a constant drain current, controlled by its source gate, while the channel gate potential varies without interfering with the current magnitude. The MMT also affords a compact footprint and tolerance to large variations in drain‐source voltage caused by LED operating conditions or power supply I × R drops.
