Nt61219h-c6021a Cof Datasheet | ((link))

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:

The is a Gate or Source Driver IC manufactured by Novatek Microelectronics Corp. . It is a "Chip on Film" (COF) component, where the semiconductor die is bonded directly to a flexible substrate (film), allowing it to connect the T-Con board or PCB to the glass panel. 2.
