In this paper, a novel gate driver using 8-phase clock signals with seven-eighths overlapping, capacitorless, 1-to-4 noise-free sharing architecture, and bidirectional scanning function are applied in the circuit design. The reliability verification result shows good performance after 800 hours stress at 85oC measurement.
