Chip-on-film panel structure

A chip-on-film panel structure comprising a panel body, a plurality of fan-out leads mounted on the panel body, a plurality of first metal sheets mounted on the panel body and used to be connected to the fan-out leads, a plurality of array leads mounted on the panel body and a plurality of second metal sheets mounted on the panel body and used to be connected to the array leads, characterized in that:

• the array leads are disposed at two sides of the fan-out leads, the second metal sheets are disposed at two sides of the first metal sheets, the length of each of the second metal sheets is less than the length of each of the first metal sheets to form a lead-out area, and the array leads are led out from the second metal sheets via the lead-out area;
• the first metal sheets and the second metal sheets are mounted parallel to each other, and each of the metal sheets has a first end and a second end, wherein the first ends of the first metal sheets are connected to the fan-out leads, the first ends of the second metal sheets are aligned with the first ends of the first metal sheets, and the lead-out area is positioned beside the second ends of the second metal sheets;
• the array leads are led out from the second ends of the second metal sheets;
• the length of each of the second metal sheets is ⅓ up to ⅔ of the length of each of the first metal sheets;
• the width of each of the second metal sheets is greater than the width of each of the first metal sheets;
• and
• the area of each of the second metal sheets is determined by the area of each of the first metal sheets.
