Product Description:
This HDMI to eDP driver board is designed for 10‑inch to 18.4‑inch laptop LCD panels (eDP interface, 30‑pin or 40‑pin). No firmware programming needed– it automatically adapts to multiple resolutions. Features a scroll wheel for brightness adjustment (10%–100%) and on/off, with brightness memory after power‑off.
