A High-Performance Micro Light-Emitting Diode Pixel Circuit Based on LTPO TFTs using a Pseudo Digital Driving Method

Late-News

Description:

This paper proposes a novel PWM pixel circuit for µLED modular displays using a pseudo digital driving method and external compensation. It simplifies the circuit with a stepwise signal and inverter, achieving stable operation (<1% error) under ±0.2V variations, <30 ns transient time, and 8-bit grayscale without internal compensation.
