Want to now if screen is same material as iphone 4

Probably not; it’s a big marketing bullet point for the iPhone 4, as is the oleophobic (anti-fingerprint) coating. The LCD in the iPod Touch 4G uses a cheaper (non-IPS) technology, and the glass is probably also cheaper to bring the overall cost down.
