We used ultraviolet picosecond lasers for etching experiments. It achieves high precision and non‐destructive etching of ink printing and high reflective coating. By adjusting laser power, laser energy density, scanning speed, scanning mode and other parameters, it meets the follow‐up process requirements of mini‐LED backlight.
