: A single dead or permanently high column output pin usually produces thin, pixel-wide vertical lines spanning from the top of the display to the bottom. nt61219h-c6021a cof datasheet
Quick checklist before production
You need a pulse heat bonding machine (ACF bonder), a microscope for alignment, and ACF tape (width matching the 35µm pitch). Manual soldering is impossible due to the fine pitch. The is a workhorse component in mid-to-large sized
Use conductive anti-static trays and grounded wrist straps. Do not bend the COF within 2mm of the IC edge.
: If the COF IC responsible for the main data lines fails, the entire screen or a large section may remain black. STMicroelectronics Community Repairing these components requires a COF bonding machine This link or copies made by others cannot be deleted
