: Description of how the COF was measured, such as using a tribometer. cof data sheet

A (Chip-on-Film) is a technical document that outlines the electrical, mechanical, and functional specifications of a driver integrated circuit (IC) mounted on a flexible film substrate. These sheets are vital for engineers and technicians repairing LCD, LED, and OLED display panels, as they provide critical "pinout" data required for "flying line" repairs—restoring broken signals by bypassing damaged film traces.

This is the most crucial part of the document for repair work. it identifies the exact function of each pin on the driver IC, such as VGH (high gate voltage), VGL (low gate voltage), and VDD (operating voltage). Core Components of a COF Data Sheet This

COF technology is essential for modern electronics with "slim bezels" because the film can be folded, allowing the driver IC to be tucked behind the display panel.

A comprehensive data sheet for a Chip-on-Film component typically includes several key technical sections:
