What to salvage from an old pc monitor

I recently took apart an old pc monitor and a desoldered every single component off the circuit board, but I’m not sure what to do with all the strange (maybe plastic I don’t know) sheets. Any ideas on if their useful or not and what I can do with them?
Thank you,
Ben

You talking about the IC's or the PCB itself ?
