Abstract

An identifier for identifying a source driver of a chip-on-glass liquid crystal display and an identifying method thereof are provided. The identifier includes a comparator for receiving a chip identity and a target identity, and generates a triggering signal to activate the source driver if the chip identity coincides with the target identity.
