The wider, more robust copper traces on one side of the film receive low-voltage control signals and power from the source PCB.

The COF receives serialized video data, deserializes it via a shift register, latches one horizontal line, applies gamma correction (via internal resistor ladder or external references), and drives the pixel capacitors at high voltage. The wider, more robust copper traces on one

But to fix it, Elias needs more than just a spare part. He needs the —the "map" of the chip's soul. In the quiet of his shop, he searches for the specific voltage points that make the chip breathe:
